micro-based explanation for monetary nonneutrality Secondeven small menu costs may be sufcient to generate substantialaggregate nominal rigidity and large business cycles1 Conse-quently menu costs have received considerable attention in thetheoretical macroeconomics literature as many predictions gener-ated by traditional Keynesian and more recent new Keynesianmodels crucially depend on the existence of some form of pricerigidity2

Despite the theoretical importance of menu costs howeverlittle is known about their actual magnitude as the above quota-tion from Blinder succinctly reects Because of the practical dif-culty of measuring menu costs directly a common feature of theexisting empirical studies of menu costs is that they all provideindirect evidence3 Yet many authors including Blinder [1994]Kashyap [1995] and Slade [1996a] have emphasized the impor-tance of assessing the empirical relevance of menu costs at thelevel of individual rms For example according to Slade [1996ap 19] ldquoGiven the large number of theoretical papers that evalu-ate the implications of [price] adjustment costs obtaining directevidence that such costs are present seems crucialrdquo

Our primary contribution in this paper is providing directmeasures of menu costs at ve large U S retail supermarketchains Using a unique store-level data set we show that chang-ing prices in these establishments is a complex process requiringdozens of steps and a nontrivial amount of resources The menucosts reported in this study are made up of (1) the labor cost ofchanging shelf prices (2) the costs of printing and delivering newprice tags (3) the costs of mistakes made during the price changeprocess and (4) the cost of in-store supervision of the pricechange process4 We nd that the measurable components ofmenu costs for the four chains that are not subject to an item

QUARTERLY JOURNAL OF ECONOMICS792

price law average $105887 annually per store In relative termsthese menu costs comprise 070 percent of revenues 352 percentof net margins and $052 per price change on average

Our second major contribution in this paper is providing evi-dence that these menu costs can form a barrier to price changeactivity at these chains offering direct support for the relation-ship between menu costs and store-level individual price rigidityWe present three types of evidence that these menu costs form abarrier to price change activity at these rms First we contrastthe price change activity of a chain that operates in a state withan item pricing law with the rst four chains that operate instates not subject to such laws Item pricing laws require that aseparate price tag be placed on each individual item sold (in addi-tion to the shelf price tag) We show that the average menu costper price change for the chain subject to the item pricing law is$133 over two and a half times the corresponding gure for theother four chains ($052) These larger menu costs lead to verydifferent levels of price change activity by these chains Specifi-cally the four supermarket chains that are not subject to itempricing laws on average change prices on 156 percent of the prod-ucts they carry each week In contrast the chain that is subjectto the item pricing law (and therefore faces higher menu costs)changes prices on only 63 percent of the products it carrieswhich is less than half the average of the other four chains

Second within the chain facing the item pricing law thereare 400 products that are exempt from this law and thereby facelower menu costs For these products the chain each weekchanges the prices of 21 percent of the products on average whichis over three times more frequently than for products subject tothe item pricing law Third we provide evidence from the super-market chains that the menu costs they incur form a barrier tocertain cost-based price adjustments Specically we show thatthe chains not subject to item pricing laws each week experiencecost increases on about 800ndash1000 products they sell Yet they ad-just prices of only about 70ndash80 percent of these products Theremaining 20ndash30 percent of the prices are not adjusted immedi-ately because the existing menu costs make the necessary priceadjustment unprotable Considering all three of these ndingstogether we conclude that menu costs can indeed affect pricechange activity at the level of the individual rmmdashoffering directevidence that these menu costs are relevant to marginal pricechange decisions Finally on a related macroeconomic issue we

THE MAGNITUDE OF MENU COSTS 793

provide empirical evidence which suggests that the price changeprocess in these supermarket chains has a strong time-dependent element

Relating our ndings to the existing theoretical models weconclude that the magnitude of the menu costs we nd is largeenough to be capable of having macroeconomic signicance Firstrecall that according to the studies of Akerlof and Yellen [1985]Mankiw [1985] Parkin [1986] and Caplin and Leahy [1997] evensmall menu costs can be relevant since they may be sufcient togenerate substantial aggregate nominal rigidity and thus largebusiness cycles Second when considered in the context of thetheoretical menu cost models of Blanchard and Kiyotaki [1987]and Ball and Romer [1990] we nd that the menu cost gureswe report are ldquonontrivialrdquo and their relative magnitudes cross theminimum theoretical threshold needed to form a barrier to priceadjustments

Although in this paper we provide direct measurements ofthe marginal costs associated with changing prices it should bementioned that there are still many aspects of menu costs we areunable to measure In particular we do not provide measure-ments of the marginal benets associated with changing priceswhich can be signicant [Lieberman and Zilberfarb 1985 She-shinski and Weiss 1977] At the local level this industry is ex-tremely competitive [Calatone et al 1989 Progressive GrocerNovember 1992 p 50 Chevalier 1995] In such a competitive in-dustry the benets of frequently changing prices can be high asunmatched price cuts or consumer perceptions of higher pricescan lead to signicant losses in sales5 This helps explain whydespite the magnitude of the menu costs we found we still ob-serve frequent weekly price change activity by the chains westudy For example stores change an average of 15ndash16 percent oftheir prices each week Also they seem to adjust the prices of70ndash80 percent of the products for which they experience cost in-creases6 Thus although we have evidence that the menu costswe report in this study clearly matter in the sense that they cre-

5 Also changing prices frequently can make it more difcult for customersto compare prices of branded items across supermarkets because of higher searchcosts [Carlton 1986] which is valuable for creating differentiation between retailoutlets [Bergen Dutta and Shugan 1996]

6 This level of price change activity is similar to that found in other studiesof U S supermarket prices [Dutta Bergen and Levy 1995] although the pricereaction to cost changes can be signicantly more rigid depending on the natureof the cost changes the retailer faces [Levy Dutta and Bergen 1996]

ate some barriers to price change activity at these retail super-market outlets they are not large enough to prevent a signicantshare of prices to adjust

The paper is organized as follows In Section II we describethe data In Section III we discuss the price change process insupermarket chains and report absolute measures of menu costsIn Section IV we assess the effect of item pricing laws on menucosts In Section V we discuss the signicance of the menu costsWe end with conclusions and suggestions for future research

II DATA DESCRIPTION

The data come from a company that sells electronic shelf la-bel (ESL) systems These systems allow retailers to change theshelf prices electronically from a central computer (where pricechanges are actually done) via a wireless communication systemand thus reduce the physical costs and lead times currently asso-ciated with changing shelf prices In order to sell the product thecompany needed to validate what the existing costs of changingshelf prices were in supermarket chains ie the existing levelsof menu costs This company received access from corporate head-quarters at each of the ve chains in our sample to go to represen-tative stores and carefully record the exact steps involved in theprice change process These studies considered the entire pricechange process in each chain For this detailed work-ow sche-matics of each task in the price change process was developedObservations of the process were conducted in multiple stores ofthe chains (at least two representative stores for each chain) toverify its accuracy Information received from chainsrsquo pricing sys-tems in-store observations in-store counts and in-store timemeasurements (with a stopwatch) were used to determine thevolume of work performed in each step of the tasks weekly fre-quency of each step performed and the exact amount of time re-quired to perform one unit of the work After computing the totalhours per task this information was reconciled with the knowntotal hours spent each week This allowed for task level compari-sons for the existing and test process Each study required hun-dreds of man-hours to create The studies were conducted duringthe years 1991ndash1992

Although we believe the menu costs reported in this paperare representative of menu costs in the U S supermarket indus-try we should mention that they may be biased upward because

THE MAGNITUDE OF MENU COSTS 795

the rm had an incentive to overestimate the magnitude of themenu costs in order to sell the ESL system We think howeverthat the menu cost measures we report in this paper are not sub-ject to signicant biases of this sort for a number of reasonsFirst the ESL people measured and documented all price changeactivities jointly with the supermarket employees using the wagegures provided by the supermarket management Second timeand motion measurements of the type used for measuring themenu costs we report here are routinely done by supermarketchains themselves in order to assess the efciency of their pricechange processes The supermarket managers compared theirgures to the ESL company gures and found them to be similarFurther these gures were presented to upper management ofthese chains and were found to be representative of their coststructures In fact the validity of the menu cost measures con-structed by the ESL company was never disputed If there wasany disagreement between the ESL company and the supermar-ket chains it was about the size of the savings the ESL systemwould provide not about the accuracy of the menu cost measure-ments7 Further we looked at these reports and searched for g-ures that could be biased upward There were a few such as lossof goodwill costs and inventory holding costs and to be on theconservative side we did not include them in our measures ofmenu costs Thus we only report gures for which we could seeno upward bias Finally note that the menu cost gures we reportare clearly biased downward because we were unable to measurein dollar terms several components of menu costs and thus theyare not included in our gures (see subsection III5 for details)

Table I displays some general information about the super-market chains we study their pricing strategy and informationabout the frequency of weekly price changes the stores under-take The chains involved in this study are all large U S super-market chains from different regions in the United Statesranging from the Northeast to the West Coast and operating anaverage of 400 stores each At the request of these retailers wewill keep the companies in this study anonymous but they areall large multistore chains that seem reasonably representativeof large supermarket chains currently selling in the United

a HL (HighLow) and EDLP (Every Day Low Price) refer to the general pricing strategy followed by theretail chain Under the EDLP strategy the retailer rsquos prices are low for extended periods of time and there-fore it will offer fewer promotional sales or discounts Under the HL pricing strategy in contrast the retail-errsquos prices are higher and the retailer tends to offer more frequent discounts through sales and promotionsSee the text for more details

b The share of products for which prices change on an average week is the ratio of number of pricechanges per store per week to 25000 The latter is the average number of products carried per store eachweek

States These chains are similar in the variety selection andquantity of the products they carry Supermarket chains of thistype make up $310146666000 in total annual sales which is863 percent of total supermarket chain sales in 1992 [Supermar-ket Business 1993] so the chains in our sample are representativeof a major class of the retail grocery trade

According to the second row in Table I the number of weeklyprice changes in Chains AndashD ranges from 3223 to 4316 for anaverage of 3916 per store8 The variation in the number of weeklyprice changes across the chains is due in large part to their choiceof pricing strategy Chains A and B follow a highlow (HL) pricestrategy while Chains C and D follow an everyday-low-pricestrategy (EDLP) Under the EDLP strategy the retailerrsquos pricesare low for an extended period of time and therefore it will offerfewer promotional sales or discounts Under the HL pricing strat-egy in contrast the retailerrsquos prices are higher and the retailertends to offer more frequent discounts through sales and promo-tions The pricing strategy therefore will have an effect on thefrequency of price changes observed In particular we would ex-

pect EDLP stores to have less frequent price changes in compari-son to the HL stores Indeed according to Table I Chains A andB tend to have a higher number of weekly price changes (4278and 4316 respectively) than Chains C and D (3846 and 3223respectively)

Supermarkets of the size we study tend to carry around25000 different items on a regular basis9 The last row in thetable presents the share of the 25000 products for which the su-permarket chains change their prices in a period of one weekThe average share for the four chains is 1566 percent

III ABSOLUTE MEASURES OF MENU COSTS

There are four components of menu costs that we are able tomeasure in dollar terms10 These are (1) the cost of labor requiredto change the shelf price tags (2) the cost of printing and deliv-ering new price tags (3) the cost of mistakes made during theprocess of changing prices and (4) the cost of in-store supervisiontime spent on implementing price changes

III1 Costs of the Labor Required to Change Shelf Prices

Figure I displays an overview of the steps involved in chang-ing prices at Chain A There are three main components in thelabor costs incurred by the chains (a) labor cost of tag changepreparation (b) labor cost of the tag change itself and (c) laborcost of verifying whether the price changes are done correctlywhich include tag change verication in-store resolution of pricemistakes and zone and corporate resolution of price mistakes11

9 The supermarkets often have about 40000 UPC codes in their computerdatabase records but internal studies undertaken by the ESL company indicatethat the supermarkets usually carry no more than 25000 products at any giventime The extra UPC codes are for seasonal or promotional sizes and packages ofproducts and for discontinued products

10 In this paper we only report measures of the marginal cost of changingprices The costs of putting a price tag for the rst time and other costs thatwould be included in the average cost are not included in the gures we reportOnly when discussing Chain E which is the chain subject to item pricing lawsdid we face the issue of cost of pricing (at the rst time) versus the cost of changinga price Since there was no clear way of separating the two types of costs thereported cost gure ($44168 in the second paragraph of Section IV) was excludedaltogether from our calculations Also see footnote 13

11 For a detailed description of the entire price change process with ow-charts documenting the specic steps undertaken in this process and the exacttime period spent on each step see Levy Dutta Bergen and Venable [1997] Anappendix reporting computational details are contained in a working paper ver-sion of this paper which is available upon request

Standard price tag changes which include the steps outlined onthe left-hand side of Figure I make up the majority of pricechanges in these chains Some price changes also require addi-tional price signs to be placed at different locations in the storesuch as on an end of aisle display or near the shelf12 These sign

Table II lists each stage of the price change process the totalamount of time spent on each stage each week on average andthe number of tasks performed In addition the table identiessome of the main tasks performed in each stage as well as thefour most time-consuming tasks in each stage To compute thetotal labor time used in changing prices on a weekly basis wecombine the data collected through in-store time and motion ob-servations with information on the volume of products for whichprices are changed These weekly hours are multiplied by thewage rates (adjusted for fringe benets) of the employees used inthe price change process to get the total costs of labor required tochange prices

For the four supermarket chains in our study the total an-nual labor cost of changing the shelf price tags ranges from$40027 to $61414 per store for an average of $52084 (see therst row in Table III making up about 49 percent of the totalmenu costs on average The labor cost of changing the price signsrange from $16411 to $27955 per store for an average of$22183 (see the second row in Table III) making up almost 21percent of the menu costs on average Thus for the four super-market chains the total annual menu costs associated with thelabor required to change prices (shelf price tags and price signscombined) range from $62210 to $81703 per store for an annualaverage of $74267 This is the single largest component of themenu costs we report in this study making up about 701 percentof the total menu costs for these chains on average This shouldnot be surprising given that the most signicant portion of retail

are longer because they are in less standard locations and (ii) there are fewersign changes than standard shelf price tag changes

13 The menu cost measures we report do not include the cost of changingprices in cases where items are moved from shelf to shelf or where shelf space isreallocated by increasing the shelf space for some products at the expense of oth-ers However they do include the cost of pricing new products when they are rstintroduced While this could bias the menu cost measures upward since it reallycaptures the cost of pricing rather than the cost of changing price the size of thisbias is marginal due to the small number of new products For example accordingto ESL company executives the number of new products introduced at thesechains each week ranges from 20 to 100 approximately In comparison to the num-ber of products for which prices are changed each week (3223ndash4316) the biasis negligible

grocery operating expenses is labor costs [Hoch Dreze andPurk 1994]14

III2 Costs of Printing and Delivering New Price Tags

There are direct costs associated with printing and deliv-ering the price and sign tags The order must be recorded andprocessed at the chain sent to the printer recorded and pro-cessed at the printer printed packaged and then delivered toeach store The cost per tag is usually quite low $0017 per tagat Chain A which includes stock costs of $00118 per tag impres-sion and data center operator costs of $00037 per tag and mailroom handling costs of $00010 per tag There are however manyprice changes undertaken each week In total the costs of print-ing and delivering the price and sign tags range from $3048 to$10018 averaging $6014 per store per year (see Table III)These costs comprise less than 6 percent of the total menu costswe report

III3 Costs of Mistakes Made in the Process of Changing Prices

Despite the labor put into checking to make sure that theprice changes are done correctly there are still many price mis-takes that are not caught until customers discover them through-out the week and these mistakes impose costs on the chainClearly the costs associated with these errors must be consideredwhen deciding whether to change prices or not and therefore area relevant dimension of menu costs These mistakes can occur sooften that they were a feature of a Dateline segment on U Ssupermarket chains [NBC April 1992] and an article in MoneyMagazine [April 1993] Both the Money Magazine article andGoodstein [1994] report that on average 10 percent of the prod-ucts they examined had price mistakes A more recent study bythe Federal Trade Commission [1996] reports a total error rate ofabout 5 percent

The menu costs associated with these mistakes include lost

14 Our measure of labor cost may overstate the true costs of changing pricesif supermarkets hoard labor to save hiring and ring costs However this is notlikely to be the case for several reasons First the labor costs of changing priceswe report are based on actual measurements of the minimum amount of time andlabor required to accomplish the task rather than on the number of employeeshired to change prices at the store Second the adjustment in the amount of laboris usually done through hours worked which makes cost of hiring and ring lessrelevant And third the workers on the oor are routinely moved from task totask according to the need These tasks include stocking cleaning price changingcustomer service etc The workers employed by supermarket chains are alwaysbusy and so the opportunity cost of changing price is not zero Therefore laborhoarding is not likely to be an important factor in our measurements

QUARTERLY JOURNAL OF ECONOMICS806

cashier time to correct the errors scan guarantee refunds andinventory mistakes associated with incorrect price tags15 Lostcashier time is measured here in terms of wage payments Scanguarantee refunds are additional price reductions beyond the er-ror or additional items given away for free because of the mis-take Finally the inventory mistakes costs we report include onlythe cost of stockouts which occur when shelf price is lower thanintended

The mistake costs were available at Chains A C and D andthey range from $19135 to $20692 for an average of $20140 perstore annually (see Table III) These costs are the second largestcomponent of menu costs in our study comprising about 19 per-cent of the total

III4 Costs of In-Store Supervision Time Spent on ImplementingPrice Changes

Managers at the store level spend time overseeing imple-menting and troubleshooting the price change process OnlyChains A and B had a measure of the menu costs associated withthis in-store supervision time and both of these came from a self-reported number of hours spent on changing prices by the manag-ers at these chains The hours spent on changing prices were thesame across the chains approximately ve hours per week Thusthe menu costs for in-store supervision time came to $4241 and$6692 per store annually for Chains A and B respectively (seeTable III) These costs comprise less than 6 percent of the totalmenu costs we report in this paper However notice that thesemeasures do not include the cost of the management time spenton price change decisions made at corporate headquarters whichis discussed next

III5 Components of Menu Costs We Are Unable to Measure inDollar Terms

Our data set does not contain the exact dollar measures ofsome menu cost components One such component is the cost ofcorporate management time spent on price change decisions16 In

15 Other likely costs of price mistakes that we do not consider explicitlybecause we are unable to measure them in dollar terms are legal problems (whenthe scanner price is higher than the shelf price) loss in customer goodwill anddecreased protability (when the scanner price is lower than the shelf price)

16 It has been suggested that the cost of managerial decisions is one of themost important components of menu cost See for example Ball and Mankiw[1994] Kashyap [1995] and Meltzer [1995] Since the ESL system was not de-

THE MAGNITUDE OF MENU COSTS 807

the supermarket chains we study prices are generally set at cor-porate headquarters in a weekly meeting where the manager incharge of setting prices looks at a variety of information including(a) any manufacturer wholesale price changes promotions andother related issues (b) past sales for this product and (c) com-petitorsrsquo prices Based on this information and on discussionswith other managers the price-setting manager decides whetherto change prices and if so by how much

To estimate the magnitude of these managerial componentsof the menu costs consider the following In an average chainthere is at least one executive of merchandising who devotesmost of hisher time to pricing decisions In addition there areup to three senior managers who would deal with pricing andto whom category managers report There are also ten-to-twelvecategory managers who are responsible for setting prices on allthe products within their category An additional two-to-fourpeople spend full time handling the implementation of pricechanges across retail outlets coordinating the printing and deliv-ery of price tags and handling pricing problems in the systemAnother ve-to-seven workers gather the data on competitorsrsquoprices and analyse both the competitorsrsquo data and the storersquos ownscanner data to put it in a form useable by managers makingpricing decisions Thus in total there are about 21ndash27 peopleworking at the corporate headquarters on price change decisionsAssuming $150000 as the average annual salary of the executiveof merchandising and senior managers $100000 for categorymanagers and $50000 for the rest the chainwide managerialcost falls in the neighborhood of $23ndash$29 million a year whichseems a substantial amount However note that these pricing de-cision are made for the entire chain and therefore the costs perstore are signicantly less especially for the larger chains Forexample using $29 million as the upper bound the additionalannual menu cost per store for Chains AndashD which on averageoperate about 400 stores each averages about $7250 which ismuch lower than expected and is due to the centralization of theprice change decisions in the chains we study17

signed to save the costs of corporate headquarter managerial time spent on pricechange decisions the ESL company did not measure this component of menucosts The estimates reported in this section are based on the information receivedfrom the ESL company executives

17 A decentralization of the price change process say by allowing the store-level managers to make price change decisions can change these gures tremen-dously For example consider the following thought experiment conducted using

QUARTERLY JOURNAL OF ECONOMICS808

Our menu cost measures also do not include the cost ofchanging prices of direct store delivery (DSD) products Theseproducts are almost completely handled by manufacturers in-cluding stocking monitoring inventories and setting and chang-ing prices18 We have data on the weekly frequency of pricechanges of DSD products in Chain E In an average week thereare 174 price changes of DSD products which is about 10 percentof the supermarketrsquos total weekly price changes Using the costof changing the price of a regular product $133 (see Section IVfor details) the annual cost of changing prices of the DSD prod-ucts in this chain roughly equals $1203419 Our menu cost mea-sures do not include these gures since we do not have similardata for the other chains20

III6 Total Menu Costs

The total annual menu costs reported for each chain perstore are listed in the last row of Table III As the table indicatesthe menu costs range from $91416 to $114188 for an average of$105887 per store per year21 Note that these menu cost mea-

the average annual per store gures for Chains AndashD Suppose that the supermar-ket chains decentralize the price change process by hiring for each store only one-quarter of the price change managing team while at the same time they com-pletely eliminate the corporate level team The resulting annual menu cost perstore would be $830887 ( 5 $105887 1 $725000) which would dwarf any of themeasurable menu cost gures we report in this study Even if the average storeonly hired just the merchandising manager at the annual cost of $150000 itwould still incur annual managerial cost of about $255887 ( 5 $105887 1$150000) In other words such a trivial decentralization would double the store-level menu costs This would indeed make the cost of price change decisions themost important component of menu cost

18 DSD products usually are high-volume fast-moving or perishable prod-ucts such as milk soda eggs bread dairy snacks etc In the chains we studyabout 10ndash20 percent of the products are of a DSD type but that share may reachas much as 40 percent of the products carried [Direct Store Delivery Work Groupet al 1995]

19 The process of changing prices of DSD and of regular products is similarBut with DSD products there are additional costs of the time spent on driving tothe store parking and setting up the price change process at each store

20 Our measures of menu cost also do not incorporate the cost of informingconsumers about price changes which can take a variety of forms such as newspa-per ads and inserts TV and radio ads in-store promotion signs etc Finally wehave no data on lost customer goodwill and damaged reputation caused by dis-crepancies between price tag and cash register [Okun 1981 Carlton and Perloff1994 Haddock and McChesney 1994]

21 The variation in the menu costs across the chains is mostly due to wagerate and labor-efciency variations Also note that since the supermarket chainsin our sample are similar in the size of their stores carry similar sets of productsand follow similar processes of price change and price change decisions it is rea-sonable to believe that the chains incur similar types of costs Therefore as notedunderneath Table III these menu cost measures are computed by replacing theunreported gures by the averages of the available values from the other chains

THE MAGNITUDE OF MENU COSTS 809

sures include only the components we could accurately measurein dollar terms which are discussed in subsections III1ndashIII4

IV ITEM PRICING LAWS AND MENU COSTS

In this section we provide evidence on the menu costs for anadditional chain (Chain E) which unlike the other four chainsoperates in a state with an item pricing law The most importantaspect of item pricing laws is that they require a price tag on eachindividual item sold not just on the shelf which is what the otherfour chains in our sample do For example the item pricing lawin Connecticut requires that the grocers ldquoshall mark or cause tobe marked each consumer commodity which bears a UniversalProduct Code with its retail pricerdquo 22 From a menu cost perspec-tive the requirement of posting prices on every item (in additionto the shelf price tag) introduces additional costs in the processof changing prices

Although most of the steps involved in changing prices arethe same for both types of chains stores that are subject to itempricing laws have to undertake additional steps to obey this law23

The labor cost component of menu costs in Chain E totals $75127a year of which $49710 is the cost of the labor time spent onchanging the prices of individual items $3234 is the cost of thelabor time spent on shelf tag replacements and $22183 is thecost of the labor time spent on sign changes (see Table III)24 Anadditional $44168 is spent annually putting prices on new itemsas they are brought to the shelves Although we do not includethis last gure in our menu cost measures because we do not haveinformation on how much of it is due to price change activity andhow much due to just pricingmdashthese costs are clearly a directconsequence of the item pricing law The printing and deliverycost of price tags and price signs are $7644 and the mistake

22 Public Act No 75ndash391 An Act Concerning Pricing of Consumer Merchan-dise [Public Acts of the State of Connecticut 1975 Vol 1 p 390]

23 These steps which are in addition to the regular steps undertaken toreplace price tags on the shelves include (1) obtaining item price tags (2) settingup workstations (3) locating the product (4) removing an item from the shelf (5)removing old price tag (6) setting marking gun (7) applying new price tag and(8) returning the item back to the shelf

24 Since we do not have a measure of the cost of labor time spent on signchanges and the cost of in-store managerial supervision time for this chain weuse the average of the chains that report them (A and D) Note also that thehourly wage rate of $907 paid by Chain E is lower than the hourly wage of about$1400ndash$2000 paid by Chains AndashD

QUARTERLY JOURNAL OF ECONOMICS810

25 Further note that the chains with smaller menu costs are likely tochange their prices more frequently which suggests that the gures of the totalannual menu costs understate the differences between Chain E and the otherchains Indeed despite the large difference in the menu cost per price change thetotal annual menu costs per store for Chain E ($109036) are more comparable tothose of Chains AndashD ($105887)

26 In calculations that follow we use industry averages because (1) thechains did not share this proprietary information with us and (2) we were re-quired to keep the identity of these chains condential as some of these numbersare detailed enough to enable some readers to identify the chains under study

costs are $20799 These gures along with the amount of $5466for the cost of in-store managerial supervision time yield totalannual menu costs of $109036 per store

Although the magnitude of the total annual menu costs seemsimilar to the other four chains note that the average weeklyfrequency of price changes in Chain E is only 1578 which is only403 ( 5 15783916) percent of the price changes made by theother four chains Thus the average menu cost per price changefor Chain E is $133 (see Table IV last row) In contrast the corre-sponding gures for Chains AndashD average $052 Hence the menucosts per price change incurred by the supermarket chain facingitem pricing laws are more than two and a half times the amountincurred by chains that are not subject to this law25 Overallthese ndings suggest that legal restrictions of the type of itempricing laws can have a signicant impact on the menu costs in-curred by sellers

V SIGNIFICANCE OF THE MENU COSTS

The next natural question to ask is how important are thesecosts To address this question we (1) provide several relativemeasures of the menu costs (2) discuss the effect of the menucosts on supermarketsrsquo price change activity and (3) discuss mac-roeconomic implications by relating our ndings to the existingtheoretical models of menu costs In each case we provide addi-tional evidence to help assess the importance of these menu costs

V1 Relative Measures of the Menu Costs

In order to assess the relative magnitude of the menu costsreported in Section IV we now present the menu cost gures rela-tive to the average store-level revenues and net prot margins26

In addition we present the menu cost gures per price changeThe annual average revenues of a large U S supermarket

chain of the type and size included in our sample is $15052716

per store27 According to the second row of Table IV the ratio ofmenu costs to revenues for Chains AndashD ranges between 061ndash076percent averaging 070 percent28 We relate the size of thesegures to the existing theoretical menu cost models in sub-section V3

Net prot margin which measures the revenues minus allcosts is approximately 1ndash3 percent of revenues for these chains[Montgomery 1994] so we use 2 percent as a working averageThe reason for the low prot rate in this industry is the intensecompetition [Calatone et al 1989] especially at the regional level[Chevalier 1995] which has been increasing since the early 1990s[Progressive Grocer November 1992 p 50] It follows that theaverage store protability for these chains equals $301054 peryear Therefore the ratio of total menu cost to net margin forChains AndashD ranges between 304ndash379 percent for an average of352 percent Thus the menu costs we report in this study repre-sent a signicant share of supermarketsrsquo prots

Another way to look at the menu cost gures we report is toexpress them relative to the frequency of price changes In thelast row of Table IV we present the menu cost gures per pricechange for each chain As the table indicates the cost of changinga price in Chains AndashD ranges between $046ndash$068 for an averageof $052 For Chain E the gure is substantially larger $133 perprice change29 These gures are lower than the estimated cost of

27 This is the average of two different estimates $12945432 and$17160000 The source of the rst gure is internal record of a supermarketchain of the type and size studied here The second gure comes from Supermar-ket Business [1993 p 52]

28 We also measured the menu costs in terms of controllable operating ex-penses (which are the portion of costs that the retailer has direct control over andtherefore are often the costs that the retailer is most focused on managing) andgross margins (which measure the supermarket revenues minus direct cost of theproducts it sells) We nd that the menu costs comprise 313 percent of controlla-ble operating expenses and 281 percent of gross margins at these chains on aver-age Finally if we measure the menu costs relative to the number of productscarried per store (about 25000) then we nd that the menu costs per productaverage $423 for Chains AndashD See Table IV and its footnotes for details

29 We can also try to express the menu cost gures relative to the numberof individual items sold by these chains each year (Note the difference betweennumber of products carried and number of items sold As an example a TartarControl Crest 8oz would be considered a product carried and 300 units of themsold per year would be considered number of items sold) Using $170 as the aver-age price of all the products sold we nd that the menu cost per item sold for thefour chains is in the range of $00103ndash$00129 for an average of $00119 (see TableIV second to last row) To see the relative magnitude of these gures note thataccording to Berkowitz Kerin and Rudelius [1986 p 319] the goal of the super-market chains of the type we study ldquo is to make 1 penny of prot on each dollarof salesrdquo Thus menu cost per item sold when adjusted for the average price

THE MAGNITUDE OF MENU COSTS 813

$200ndash$300 per price change reported by Slade [1996a] Thereare several possible reasons for this (1) our menu cost gures arebased on actual measurements of the resources that go into theprice change process whereas she estimates menu costs econo-metrically as model coefcients using a mix of store-level priceand aggregate cost data (2) we cover 25000 products that thesupermarkets carry rather than a single product category (3) ourmenu cost gures do not include all components of menu costsand (4) there could be differences in wage rates that may be im-portant given the signicance of the labor cost component inmenu costs

V2 The Effect of Menu Costs on the Price Change Activity of theSupermarkets

In this section we present evidence which suggests that thesemenu costs may be forming a barrier to price change activity Tobegin with consider the effect of the item pricing law on the pricechange activity of Chain E The data on the weekly frequency ofprice changes in each chain are displayed in the last two rows ofTable I According to these gures the average weekly frequencyof price changes in Chain E is only 1578 Thus on average ChainE changes the prices of only 631 percent of its products eachweek In contrast the average weekly frequency of price changesat Chains AndashD ranges from 3223 to 4316 for the four-chain aver-age of 3916 price changes weekly So Chains AndashD change priceson 1289 to 1726 percent of their products each week yielding afour-chain average of 1566 percent Thus Chain E which facesthe item pricing law changes prices only about one-third timesas frequently as do Chains AndashD30

Moreover within Chain E there are 400 products that areexempt from the item pricing law and thereby face lower menucosts We nd that there are an average of 83 weekly pricechanges for these products yielding 21 percent of these productschanging prices So within Chain E they change prices over threetimes as frequently for products with lower menu costs than for

roughly equals one-half of their target net prot per item which seemssubstantial

30 However note that our comparison of the two types of chains may not becompletely ceteris paribus because these stores are located in different states andtherefore there may be other chain-specic factors (in addition to item pricinglaws) that distinguish these stores We do not have any specic information onthese differences We do know however that the stores in these chains are similarin size and carry similar sets of products

QUARTERLY JOURNAL OF ECONOMICS814

the products with higher menu costs Note that this nding is onthe price change activity within the same chain offering almost anatural experiment on the impact of menu costs on the chainrsquospricing behavior Hence we provide evidence both across chainsas well as across products within a chain that as the costs ofchanging price go up the frequency of price changes goes downThus the menu costs we nd are signicant enough to affect thechainrsquos price change practice

We also have additional evidence from Chains A B and Dabout these menu costs being a barrier to certain price changesand it is summarized in Table V According to the Price Manage-ment Department of Chain A the chain experiences cost in-creases on 860 products in an average week to which it wouldlike to react with a price increase31 However on average 22 per-cent of these price increases are not implemented immediatelybecause the cost of changing prices for these products is too highto make it economically worthwhile Figures of the same magni-tude were reported by other chains For example Chain D experi-ences cost increases for 961 products in an average week Out ofthese the chain adjusts prices of only 633 products The re-maining 34 percent of the prices are left unadjusted because ofthe menu costs Similarly Chain B nds it economically ineffi-cient to adjust prices of 508 ie 30 percent of its products eachweek because of menu costs This provides additional evidencethat the menu costs incurred by these chains are preventing priceadjustments to some costs changes leading to price rigidities ofthe products involved32 Note that although we do not have simi-lar data for Chain E we would expect signicantly lower num-bers on this measure at that chain These gures also suggest anupper bound on the benet of complete price exibility under thecurrent pricing practice of weekly price adjustments Howeverif new technologies (eg ESL systems) and new pricing prac-tices (eg a decentralization of the price change decisions) are

31 Our data contain information only on the frequency of cost increasesAlthough it is more than likely that the supermarkets are experiencing cost de-creases as well our data set contained no information on such decreases

32 Menu costs may even be playing a role in the observed movement towardpricing strategies that rely on fewer price changes such as EDLP [Blattberg andNeslin 1989 Lattin and Ortmeyer 1991 Marketing News April 13 1992 p 8]According to Progressive Grocer [November 1992 p 50] ldquoA growing number ofoperators say they have switched from high-low pricing [to EDLP] They cite theinefciencies of making frequent price changes rdquo Similarly Hoch Dreze andPurk [1994 p 16] state that EDLP lowers operating costs by lowering ldquo in-store labor costs because of less frequent changeovers in special displaysrdquo

adopted allowing a fundamental change in the way the pricingmechanism is currently set the managers could consider morefrequent price change activity (eg multiple times each week) asmenu costs go down

In this paper we measure the menu costs at the chainsrsquo cur-rent level of price change activity It may be worthwhile to specu-late on the shape of the cost function relating menu costs to thefrequency of price changes by assessing how these costs wouldchange if the price change activity were to increase or to decreaseIt seems likely that many of the costs we report in this paper will(approximately) change linearly with additional price changeswithin the current range of price changes the chains are under-taking (plus or minus perhaps a thousand per week) For ex-ample the labor costs associated with changing a shelf price tagcosts of verifying price changes and the costs of mistakes oc-curring during this process all increase linearly with the fre-quency of price changes This is because most of the time-consuming steps involved in the price change process must berepeated each time an additional shelf price tag is changed (seeTable II) Further we were unable to nd many tasks that gener-ated signicant returns to scale It is unclear what cost savingsare available if the price change activity drops substantially be-

QUARTERLY JOURNAL OF ECONOMICS816

low the levels it is at now Clearly if price changes were nearzero or done less frequently than weekly (say monthly) therecould be major differences in these costs

What is less clear is how these costs would change at moreextreme levels of price change activity With less frequent pricechanges the menu costs could probably be reduced signicantlyalthough the cost of deciding what prices to set initially and thecost of putting the initial shelf price tags would still remain as alower bound of the menu cost However for achieving more priceexibility by changing prices more frequently (ie multiple timeseach week) substantial changes must be undertaken At presentthe supermarket chains are set up to make the majority of theirprice changes on a weekly basis with the appropriate systems inplace to make this process most efcient For example in orderto save costs and to have higher quality price tags (eg withcolor more details greater clarity glossy etc) the chains oftensend new price tag requests to a printing shop which takes threedays to print and deliver the labels to each store Then giventhe large number of price changes taking place and the goals ofminimizing customer disruptions and labor costs (such as over-time pay) and coordinating with advertised price promotions theprices are changed in the store over a two-to-three-day period (seeTable VI) The combination of these schedule and built-in lags isacceptable under the current practice of changing prices weeklybut would have to be adjusted dramatically to allow for signifi-cantly more frequent price changes on a regular basis

Perhaps even more imposing are the costs of changing themanagerial costs associated with the current weekly system ofprice changes The process of pricing at this organizational levelis not a self-contained activity taking place in isolation from otheroperations of the supermarket management Rather it is a partof a larger system of business decisions and operations The cur-rent process of operations (such as data collection and theiranalysis management meetings coordination of the decisionsacross functional areas etc) is set up to function on a weeklybasis33 Further these management accounting and logisticssystems are currently built around a tremendous amount of in-

35 If the supermarket chains indeed restructure the entire price change pro-cess and begin to change prices much more frequently (say two-to-three times aweek) on a regular basis then the shape of this cost function could change in anunpredictable way

V3 Relating Our Findings to the Existing Theoretical Models ofMenu Costs

In order to assess the magnitude of these menu cost guresin the context of the existing theoretical menu cost literatureconsider the following calculation experiments done within theframework of two theoretical menu cost models Blanchard andKiyotaki [1987] study a general equilibrium menu cost modelwith monopolistic competition and with unit elasticity of aggre-gate demand with respect to real money balances According totheir calculations menu costs of the magnitude of 008 percent ofrevenues which they consider ldquovery smallrdquo may be sufcient toprevent adjustment of prices Ball and Romer [1990] conductsimilar calculations in the framework of a model with imperfectcompetition and menu costs They nd that for plausible markupand labor elasticity parameter values menu costs needed to pre-vent price adjustment are 070 percent of revenues which as theysuggest are nonnegligible For smaller menu costs eg 004 per-cent of the revenue which Ball and Romer consider ldquotrivialrdquo im-plausibly large values of markup and labor elasticity parametersare needed to prevent price adjustment to monetary shocks

According to the gures in Table IV the reported menu costto revenues ratio for Chains AndashD averages 070 percent rangingfrom 061 percent to 076 percent These are signicantly largerthan the ldquotrivialrdquo 004 or 008 percent gures mentioned abovesuggesting that the menu cost gures we nd here are nontrivialFurther under the model and parameter values considered byBlanchard and Kiyotaki [1987] the menu cost gures we nd arehigher than the theoretical minimum needed to form a barrier toprice adjustments Under the model and parameter values con-sidered by Ball and Romer [1990] the reported menu costreve-nue ratio for all but one chain reaches or crosses the theoreticalthreshold of 070 needed to form a barrier to price adjustmentsThe existence of numerous unmeasured menu cost componentsdiscussed in subsection III5 also raises the possibility that theactual menu costs incurred by these chains are signicantlyhigher than that threshold This suggests that the menu costs wereport may be large enough to form a barrier to nominal priceadjustments when interpreted in the context of these models

An issue of interest in this literature is time-dependent ver-sus state-dependent pricing rules (see for example Caplin andLeahy [1991]) The evidence from our data set on the timing of

THE MAGNITUDE OF MENU COSTS 819

price changes suggests that the price change decisions in thesesupermarkets have a strong time-dependent price-setting ele-ment36 For example according to Table VI the prices in Chain Aare changed weekly according to the following schedule the pricechanges of general merchandise that is advertised is done Satur-day nights grocery and produce prices are changed Sundaynights the rest of the general merchandise prices are changed onMonday nights and the prices of advertised grocery items arechanged on Tuesday nights Thus as the gures in Table VI indi-cate over 96 percent of the price changes are done during Sundayand Monday nights However this does not imply that state-dependent pricing rules are unimportant Even if price changesacross product categories follow a prescheduled weekly time ta-ble the prices of which products to change is likely to be a state-dependent decision For example it could depend on changes insupply and demand conditions such as competitorsrsquo price changedecisions Indeed Levy Dutta and Bergen [1996] use retailstore-level orange juice price and cost data to demonstrate thatthe extent of price response to cost shocks that is the extent ofprice rigidity may depend on the nature of supply shocks37

We do not want to overstate the usefulness of our data fordirectly addressing the issue of monetary nonneutrality On onehand authors such as Caplin and Spulber [1987] have demon-strated that under certain conditions individual price rigiditymay not be sufcient for aggregate price rigidity but unfortu-nately our data do not speak directly to this issue38 On the otherhand authors such as Akerlof and Yellen [1985] Mankiw [1985]Parkin [1986] and Caplin and Leahy [1997] have shown that even

36 Danziger [1983] Caballero [1989] and Ball and Mankiw [1994] suggestthat time-dependent price adjustment of the type documented here can be optimalif the cost of gathering information about the state exceeds the cost of making theprice adjustment itself

37 We also considered the possibility of convexities in the cost of changingprices Our data do not suggest many convexities since the labor time spent inthe price tag change process the cost of printing and delivering price tags andin-store supervision time do not change with the size of a price change The onlymeasurable component of menu costs that could be convex is the cost of mistakesmade the larger the price change the higher the probability of a customer notic-ing the mistake and the larger the amount required to be refunded as compensa-tion Among the unmeasured components of menu cost the cost of corporatemanagerial time may increase with the size of a price change because larger pricechanges may require more serious consideration

38 Also see Balke and Wynne [1996] and Bryan and Cecchetti [1996] Sincewe do not have measures of how menu costs change over time our data also havelittle to say about time variation in menu costs or about the relationship betweenmenu costs and ination which during the period of the data collection (1991ndash1992) averaged about 3 percent annually

QUARTERLY JOURNAL OF ECONOMICS820

small menu costs can be relevant since they may be sufcient togenerate substantial aggregate nominal rigidity and thus largebusiness cycles Therefore as Blinder [1994] Kashyap [1995]and Slade [1996a] emphasize it is important to search for directevidence that such costs are indeed present at the micro level Bydirectly identifying documenting and measuring the magnitudeof menu costs at the store level we are taking an important stepin that direction

VI CONCLUSION AND FUTURE RESEARCH

Our main contribution is that we provide direct microeco-nomic evidence on the actual magnitude of menu costs for fourlarge U S retail supermarket chains The annual menu costs perstore at these chains average $105887 comprising 070 percentof revenues 352 percent of net prot margins and $052 perprice change on average

Further we provide evidence which suggests that thesemenu costs may be forming a barrier to price changes Specifi-cally we show that (1) supermarket chains not subject to itempricing law change prices two and a half times more frequentlythan the chain that is subject to the law (2) within the chain thatis subject to the item pricing law they change prices over threetimes as frequently for products that are exempt from this lawthan for the products which are subject to this law and (3) wend that these chains do not adjust prices of up to one-third ofthe products for which they face cost increases because of menucost considerations

When we relate these ndings to the existing theoreticalmodels of menu costs we conclude that the magnitude of menucosts we nd is large enough to be capable of having macroeco-nomic signicance Specically when considered in the context ofthe theoretical menu cost models of Blanchard and Kiyotaki[1987] and Ball and Romer [1990] we nd that the menu costgures we report are ldquonontrivialrdquo and their relative magnitudescross the minimum theoretical threshold needed to form a barrierto price adjustments

Despite the high relative magnitude of the marginal cost ofchanging price that we found the data still indicate frequentweekly price changes This is because of the high marginal bene-t of changing price which is due to the erce competition foundin the retail supermarket industry That marginal benets may

THE MAGNITUDE OF MENU COSTS 821

outweigh the marginal costs of changing prices in this industryhowever does not rule out the possibility that menu costs of themagnitude we nd here can create substantial nominal rigidityin other industries or markets In less competitive industries andmarkets menu costs of the type and magnitude we documenthere are likely to have a bigger impact on the frequency of priceadjustment and consequently on the degree of price rigidity

At a minimum the direct dollar measures of menu costs wereport here can be used as a starting point for future research onmeasuring their magnitude in other industries and establish-ments We anticipate that these menu costs will be similar inother markets which rely on posted prices (such as drugstoresdepartment stores etc) because the steps involved in the pricechange process are likely to be similar What may differ are thefrequency of price changes and the labor wage rates at thesestores For example since supermarket chains change thousandsof prices each week the total annual menu costs incurred bythese chains per store are likely to be high in comparison to otherretail formats such as chain drugstores or department storesThere are however a variety of industries for which the stepsinvolved in changing prices would be signicantly different fromthose reported in our study For example business-to-businesssales which often rely on a sales force will require changes in thelist price sheets changes in the instructions to the sales forcewhich may include education and discussion with the salespeoplein the company and so forth These business-to-business pricesalso often have more complex pricing schemes including quantitydiscounts bundling and individually negotiated prices As an-other example the composition of the cost of changing the news-stand prices of magazines [Cecchetti 1986] or the prices ofproducts sold through catalogs [Kashyap 1995] are different frommany of the menu cost components we discuss here Further thending that a centralization of pricing decisions makes the store-level managerial component of menu cost relatively small sug-gests that the managerial menu costs likely are highest insettings where price change decisions are decentralized Thus fu-ture empirical work should look at menu cost and its compositionin a variety of other industries markets and products with bothcentralized as well as decentralized price change decisions in or-der to see whether the magnitude of these costs can be general-ized and benchmarks can be established Further there aretechnological changes taking place in this and other industries

that promise to alter the structure of menu costs which deserveattention At the theoretical level our ndings suggest that it maybe worthwhile to explore models which incorporate the idea ofitem pricing laws as an additional component of menu costs

THE MAGNITUDE OF MENU COSTS 825

micro-based explanation for monetary nonneutrality Secondeven small menu costs may be sufcient to generate substantialaggregate nominal rigidity and large business cycles1 Conse-quently menu costs have received considerable attention in thetheoretical macroeconomics literature as many predictions gener-ated by traditional Keynesian and more recent new Keynesianmodels crucially depend on the existence of some form of pricerigidity2

Despite the theoretical importance of menu costs howeverlittle is known about their actual magnitude as the above quota-tion from Blinder succinctly reects Because of the practical dif-culty of measuring menu costs directly a common feature of theexisting empirical studies of menu costs is that they all provideindirect evidence3 Yet many authors including Blinder [1994]Kashyap [1995] and Slade [1996a] have emphasized the impor-tance of assessing the empirical relevance of menu costs at thelevel of individual rms For example according to Slade [1996ap 19] ldquoGiven the large number of theoretical papers that evalu-ate the implications of [price] adjustment costs obtaining directevidence that such costs are present seems crucialrdquo

Our primary contribution in this paper is providing directmeasures of menu costs at ve large U S retail supermarketchains Using a unique store-level data set we show that chang-ing prices in these establishments is a complex process requiringdozens of steps and a nontrivial amount of resources The menucosts reported in this study are made up of (1) the labor cost ofchanging shelf prices (2) the costs of printing and delivering newprice tags (3) the costs of mistakes made during the price changeprocess and (4) the cost of in-store supervision of the pricechange process4 We nd that the measurable components ofmenu costs for the four chains that are not subject to an item

QUARTERLY JOURNAL OF ECONOMICS792

price law average $105887 annually per store In relative termsthese menu costs comprise 070 percent of revenues 352 percentof net margins and $052 per price change on average

Our second major contribution in this paper is providing evi-dence that these menu costs can form a barrier to price changeactivity at these chains offering direct support for the relation-ship between menu costs and store-level individual price rigidityWe present three types of evidence that these menu costs form abarrier to price change activity at these rms First we contrastthe price change activity of a chain that operates in a state withan item pricing law with the rst four chains that operate instates not subject to such laws Item pricing laws require that aseparate price tag be placed on each individual item sold (in addi-tion to the shelf price tag) We show that the average menu costper price change for the chain subject to the item pricing law is$133 over two and a half times the corresponding gure for theother four chains ($052) These larger menu costs lead to verydifferent levels of price change activity by these chains Specifi-cally the four supermarket chains that are not subject to itempricing laws on average change prices on 156 percent of the prod-ucts they carry each week In contrast the chain that is subjectto the item pricing law (and therefore faces higher menu costs)changes prices on only 63 percent of the products it carrieswhich is less than half the average of the other four chains

Second within the chain facing the item pricing law thereare 400 products that are exempt from this law and thereby facelower menu costs For these products the chain each weekchanges the prices of 21 percent of the products on average whichis over three times more frequently than for products subject tothe item pricing law Third we provide evidence from the super-market chains that the menu costs they incur form a barrier tocertain cost-based price adjustments Specically we show thatthe chains not subject to item pricing laws each week experiencecost increases on about 800ndash1000 products they sell Yet they ad-just prices of only about 70ndash80 percent of these products Theremaining 20ndash30 percent of the prices are not adjusted immedi-ately because the existing menu costs make the necessary priceadjustment unprotable Considering all three of these ndingstogether we conclude that menu costs can indeed affect pricechange activity at the level of the individual rmmdashoffering directevidence that these menu costs are relevant to marginal pricechange decisions Finally on a related macroeconomic issue we

THE MAGNITUDE OF MENU COSTS 793

provide empirical evidence which suggests that the price changeprocess in these supermarket chains has a strong time-dependent element

Relating our ndings to the existing theoretical models weconclude that the magnitude of the menu costs we nd is largeenough to be capable of having macroeconomic signicance Firstrecall that according to the studies of Akerlof and Yellen [1985]Mankiw [1985] Parkin [1986] and Caplin and Leahy [1997] evensmall menu costs can be relevant since they may be sufcient togenerate substantial aggregate nominal rigidity and thus largebusiness cycles Second when considered in the context of thetheoretical menu cost models of Blanchard and Kiyotaki [1987]and Ball and Romer [1990] we nd that the menu cost gureswe report are ldquonontrivialrdquo and their relative magnitudes cross theminimum theoretical threshold needed to form a barrier to priceadjustments

Although in this paper we provide direct measurements ofthe marginal costs associated with changing prices it should bementioned that there are still many aspects of menu costs we areunable to measure In particular we do not provide measure-ments of the marginal benets associated with changing priceswhich can be signicant [Lieberman and Zilberfarb 1985 She-shinski and Weiss 1977] At the local level this industry is ex-tremely competitive [Calatone et al 1989 Progressive GrocerNovember 1992 p 50 Chevalier 1995] In such a competitive in-dustry the benets of frequently changing prices can be high asunmatched price cuts or consumer perceptions of higher pricescan lead to signicant losses in sales5 This helps explain whydespite the magnitude of the menu costs we found we still ob-serve frequent weekly price change activity by the chains westudy For example stores change an average of 15ndash16 percent oftheir prices each week Also they seem to adjust the prices of70ndash80 percent of the products for which they experience cost in-creases6 Thus although we have evidence that the menu costswe report in this study clearly matter in the sense that they cre-

5 Also changing prices frequently can make it more difcult for customersto compare prices of branded items across supermarkets because of higher searchcosts [Carlton 1986] which is valuable for creating differentiation between retailoutlets [Bergen Dutta and Shugan 1996]

6 This level of price change activity is similar to that found in other studiesof U S supermarket prices [Dutta Bergen and Levy 1995] although the pricereaction to cost changes can be signicantly more rigid depending on the natureof the cost changes the retailer faces [Levy Dutta and Bergen 1996]

QUARTERLY JOURNAL OF ECONOMICS794

ate some barriers to price change activity at these retail super-market outlets they are not large enough to prevent a signicantshare of prices to adjust

The paper is organized as follows In Section II we describethe data In Section III we discuss the price change process insupermarket chains and report absolute measures of menu costsIn Section IV we assess the effect of item pricing laws on menucosts In Section V we discuss the signicance of the menu costsWe end with conclusions and suggestions for future research

II DATA DESCRIPTION

The data come from a company that sells electronic shelf la-bel (ESL) systems These systems allow retailers to change theshelf prices electronically from a central computer (where pricechanges are actually done) via a wireless communication systemand thus reduce the physical costs and lead times currently asso-ciated with changing shelf prices In order to sell the product thecompany needed to validate what the existing costs of changingshelf prices were in supermarket chains ie the existing levelsof menu costs This company received access from corporate head-quarters at each of the ve chains in our sample to go to represen-tative stores and carefully record the exact steps involved in theprice change process These studies considered the entire pricechange process in each chain For this detailed work-ow sche-matics of each task in the price change process was developedObservations of the process were conducted in multiple stores ofthe chains (at least two representative stores for each chain) toverify its accuracy Information received from chainsrsquo pricing sys-tems in-store observations in-store counts and in-store timemeasurements (with a stopwatch) were used to determine thevolume of work performed in each step of the tasks weekly fre-quency of each step performed and the exact amount of time re-quired to perform one unit of the work After computing the totalhours per task this information was reconciled with the knowntotal hours spent each week This allowed for task level compari-sons for the existing and test process Each study required hun-dreds of man-hours to create The studies were conducted duringthe years 1991ndash1992

Although we believe the menu costs reported in this paperare representative of menu costs in the U S supermarket indus-try we should mention that they may be biased upward because

THE MAGNITUDE OF MENU COSTS 795

the rm had an incentive to overestimate the magnitude of themenu costs in order to sell the ESL system We think howeverthat the menu cost measures we report in this paper are not sub-ject to signicant biases of this sort for a number of reasonsFirst the ESL people measured and documented all price changeactivities jointly with the supermarket employees using the wagegures provided by the supermarket management Second timeand motion measurements of the type used for measuring themenu costs we report here are routinely done by supermarketchains themselves in order to assess the efciency of their pricechange processes The supermarket managers compared theirgures to the ESL company gures and found them to be similarFurther these gures were presented to upper management ofthese chains and were found to be representative of their coststructures In fact the validity of the menu cost measures con-structed by the ESL company was never disputed If there wasany disagreement between the ESL company and the supermar-ket chains it was about the size of the savings the ESL systemwould provide not about the accuracy of the menu cost measure-ments7 Further we looked at these reports and searched for g-ures that could be biased upward There were a few such as lossof goodwill costs and inventory holding costs and to be on theconservative side we did not include them in our measures ofmenu costs Thus we only report gures for which we could seeno upward bias Finally note that the menu cost gures we reportare clearly biased downward because we were unable to measurein dollar terms several components of menu costs and thus theyare not included in our gures (see subsection III5 for details)

Table I displays some general information about the super-market chains we study their pricing strategy and informationabout the frequency of weekly price changes the stores under-take The chains involved in this study are all large U S super-market chains from different regions in the United Statesranging from the Northeast to the West Coast and operating anaverage of 400 stores each At the request of these retailers wewill keep the companies in this study anonymous but they areall large multistore chains that seem reasonably representativeof large supermarket chains currently selling in the United

a HL (HighLow) and EDLP (Every Day Low Price) refer to the general pricing strategy followed by theretail chain Under the EDLP strategy the retailer rsquos prices are low for extended periods of time and there-fore it will offer fewer promotional sales or discounts Under the HL pricing strategy in contrast the retail-errsquos prices are higher and the retailer tends to offer more frequent discounts through sales and promotionsSee the text for more details

b The share of products for which prices change on an average week is the ratio of number of pricechanges per store per week to 25000 The latter is the average number of products carried per store eachweek

States These chains are similar in the variety selection andquantity of the products they carry Supermarket chains of thistype make up $310146666000 in total annual sales which is863 percent of total supermarket chain sales in 1992 [Supermar-ket Business 1993] so the chains in our sample are representativeof a major class of the retail grocery trade

According to the second row in Table I the number of weeklyprice changes in Chains AndashD ranges from 3223 to 4316 for anaverage of 3916 per store8 The variation in the number of weeklyprice changes across the chains is due in large part to their choiceof pricing strategy Chains A and B follow a highlow (HL) pricestrategy while Chains C and D follow an everyday-low-pricestrategy (EDLP) Under the EDLP strategy the retailerrsquos pricesare low for an extended period of time and therefore it will offerfewer promotional sales or discounts Under the HL pricing strat-egy in contrast the retailerrsquos prices are higher and the retailertends to offer more frequent discounts through sales and promo-tions The pricing strategy therefore will have an effect on thefrequency of price changes observed In particular we would ex-

THE MAGNITUDE OF MENU COSTS 797

pect EDLP stores to have less frequent price changes in compari-son to the HL stores Indeed according to Table I Chains A andB tend to have a higher number of weekly price changes (4278and 4316 respectively) than Chains C and D (3846 and 3223respectively)

Supermarkets of the size we study tend to carry around25000 different items on a regular basis9 The last row in thetable presents the share of the 25000 products for which the su-permarket chains change their prices in a period of one weekThe average share for the four chains is 1566 percent

III ABSOLUTE MEASURES OF MENU COSTS

There are four components of menu costs that we are able tomeasure in dollar terms10 These are (1) the cost of labor requiredto change the shelf price tags (2) the cost of printing and deliv-ering new price tags (3) the cost of mistakes made during theprocess of changing prices and (4) the cost of in-store supervisiontime spent on implementing price changes

III1 Costs of the Labor Required to Change Shelf Prices

Figure I displays an overview of the steps involved in chang-ing prices at Chain A There are three main components in thelabor costs incurred by the chains (a) labor cost of tag changepreparation (b) labor cost of the tag change itself and (c) laborcost of verifying whether the price changes are done correctlywhich include tag change verication in-store resolution of pricemistakes and zone and corporate resolution of price mistakes11

9 The supermarkets often have about 40000 UPC codes in their computerdatabase records but internal studies undertaken by the ESL company indicatethat the supermarkets usually carry no more than 25000 products at any giventime The extra UPC codes are for seasonal or promotional sizes and packages ofproducts and for discontinued products

10 In this paper we only report measures of the marginal cost of changingprices The costs of putting a price tag for the rst time and other costs thatwould be included in the average cost are not included in the gures we reportOnly when discussing Chain E which is the chain subject to item pricing lawsdid we face the issue of cost of pricing (at the rst time) versus the cost of changinga price Since there was no clear way of separating the two types of costs thereported cost gure ($44168 in the second paragraph of Section IV) was excludedaltogether from our calculations Also see footnote 13

11 For a detailed description of the entire price change process with ow-charts documenting the specic steps undertaken in this process and the exacttime period spent on each step see Levy Dutta Bergen and Venable [1997] Anappendix reporting computational details are contained in a working paper ver-sion of this paper which is available upon request

FIGURE IOverview of the Price Change Process

POS denotes Point of Sale and refers to the cash register or the database itis connected to or both For information on the various steps undertaken in eachstage of the price change process and the amount of the labor time spent on mosttime-consuming steps see Table II

Standard price tag changes which include the steps outlined onthe left-hand side of Figure I make up the majority of pricechanges in these chains Some price changes also require addi-tional price signs to be placed at different locations in the storesuch as on an end of aisle display or near the shelf12 These sign

12 These are usually related to the product being on promotion feature ad-vertising display or in-store sale such as ldquomanagerrsquos specialrdquo ldquotodayrsquos specialrdquoetc The steps involved in making sign changes are similar to price changes Themain differences are that (i) the time required for each of the steps in sign changes

changes add to the menu costs and they are outlined on theright-hand side of Figure I the sign change preparation actualsign changes and sign change verication boxes The bottom twoboxes in Figure I are additional menu costs related to the extrasteps taken in these stores to make sure the tag and sign changeshave been done correctly13

Table II lists each stage of the price change process the totalamount of time spent on each stage each week on average andthe number of tasks performed In addition the table identiessome of the main tasks performed in each stage as well as thefour most time-consuming tasks in each stage To compute thetotal labor time used in changing prices on a weekly basis wecombine the data collected through in-store time and motion ob-servations with information on the volume of products for whichprices are changed These weekly hours are multiplied by thewage rates (adjusted for fringe benets) of the employees used inthe price change process to get the total costs of labor required tochange prices

For the four supermarket chains in our study the total an-nual labor cost of changing the shelf price tags ranges from$40027 to $61414 per store for an average of $52084 (see therst row in Table III making up about 49 percent of the totalmenu costs on average The labor cost of changing the price signsrange from $16411 to $27955 per store for an average of$22183 (see the second row in Table III) making up almost 21percent of the menu costs on average Thus for the four super-market chains the total annual menu costs associated with thelabor required to change prices (shelf price tags and price signscombined) range from $62210 to $81703 per store for an annualaverage of $74267 This is the single largest component of themenu costs we report in this study making up about 701 percentof the total menu costs for these chains on average This shouldnot be surprising given that the most signicant portion of retail

are longer because they are in less standard locations and (ii) there are fewersign changes than standard shelf price tag changes

13 The menu cost measures we report do not include the cost of changingprices in cases where items are moved from shelf to shelf or where shelf space isreallocated by increasing the shelf space for some products at the expense of oth-ers However they do include the cost of pricing new products when they are rstintroduced While this could bias the menu cost measures upward since it reallycaptures the cost of pricing rather than the cost of changing price the size of thisbias is marginal due to the small number of new products For example accordingto ESL company executives the number of new products introduced at thesechains each week ranges from 20 to 100 approximately In comparison to the num-ber of products for which prices are changed each week (3223ndash4316) the biasis negligible

grocery operating expenses is labor costs [Hoch Dreze andPurk 1994]14

III2 Costs of Printing and Delivering New Price Tags

There are direct costs associated with printing and deliv-ering the price and sign tags The order must be recorded andprocessed at the chain sent to the printer recorded and pro-cessed at the printer printed packaged and then delivered toeach store The cost per tag is usually quite low $0017 per tagat Chain A which includes stock costs of $00118 per tag impres-sion and data center operator costs of $00037 per tag and mailroom handling costs of $00010 per tag There are however manyprice changes undertaken each week In total the costs of print-ing and delivering the price and sign tags range from $3048 to$10018 averaging $6014 per store per year (see Table III)These costs comprise less than 6 percent of the total menu costswe report

III3 Costs of Mistakes Made in the Process of Changing Prices

Despite the labor put into checking to make sure that theprice changes are done correctly there are still many price mis-takes that are not caught until customers discover them through-out the week and these mistakes impose costs on the chainClearly the costs associated with these errors must be consideredwhen deciding whether to change prices or not and therefore area relevant dimension of menu costs These mistakes can occur sooften that they were a feature of a Dateline segment on U Ssupermarket chains [NBC April 1992] and an article in MoneyMagazine [April 1993] Both the Money Magazine article andGoodstein [1994] report that on average 10 percent of the prod-ucts they examined had price mistakes A more recent study bythe Federal Trade Commission [1996] reports a total error rate ofabout 5 percent

The menu costs associated with these mistakes include lost

14 Our measure of labor cost may overstate the true costs of changing pricesif supermarkets hoard labor to save hiring and ring costs However this is notlikely to be the case for several reasons First the labor costs of changing priceswe report are based on actual measurements of the minimum amount of time andlabor required to accomplish the task rather than on the number of employeeshired to change prices at the store Second the adjustment in the amount of laboris usually done through hours worked which makes cost of hiring and ring lessrelevant And third the workers on the oor are routinely moved from task totask according to the need These tasks include stocking cleaning price changingcustomer service etc The workers employed by supermarket chains are alwaysbusy and so the opportunity cost of changing price is not zero Therefore laborhoarding is not likely to be an important factor in our measurements

QUARTERLY JOURNAL OF ECONOMICS806

cashier time to correct the errors scan guarantee refunds andinventory mistakes associated with incorrect price tags15 Lostcashier time is measured here in terms of wage payments Scanguarantee refunds are additional price reductions beyond the er-ror or additional items given away for free because of the mis-take Finally the inventory mistakes costs we report include onlythe cost of stockouts which occur when shelf price is lower thanintended

The mistake costs were available at Chains A C and D andthey range from $19135 to $20692 for an average of $20140 perstore annually (see Table III) These costs are the second largestcomponent of menu costs in our study comprising about 19 per-cent of the total

III4 Costs of In-Store Supervision Time Spent on ImplementingPrice Changes

Managers at the store level spend time overseeing imple-menting and troubleshooting the price change process OnlyChains A and B had a measure of the menu costs associated withthis in-store supervision time and both of these came from a self-reported number of hours spent on changing prices by the manag-ers at these chains The hours spent on changing prices were thesame across the chains approximately ve hours per week Thusthe menu costs for in-store supervision time came to $4241 and$6692 per store annually for Chains A and B respectively (seeTable III) These costs comprise less than 6 percent of the totalmenu costs we report in this paper However notice that thesemeasures do not include the cost of the management time spenton price change decisions made at corporate headquarters whichis discussed next

III5 Components of Menu Costs We Are Unable to Measure inDollar Terms

Our data set does not contain the exact dollar measures ofsome menu cost components One such component is the cost ofcorporate management time spent on price change decisions16 In

15 Other likely costs of price mistakes that we do not consider explicitlybecause we are unable to measure them in dollar terms are legal problems (whenthe scanner price is higher than the shelf price) loss in customer goodwill anddecreased protability (when the scanner price is lower than the shelf price)

16 It has been suggested that the cost of managerial decisions is one of themost important components of menu cost See for example Ball and Mankiw[1994] Kashyap [1995] and Meltzer [1995] Since the ESL system was not de-

THE MAGNITUDE OF MENU COSTS 807

the supermarket chains we study prices are generally set at cor-porate headquarters in a weekly meeting where the manager incharge of setting prices looks at a variety of information including(a) any manufacturer wholesale price changes promotions andother related issues (b) past sales for this product and (c) com-petitorsrsquo prices Based on this information and on discussionswith other managers the price-setting manager decides whetherto change prices and if so by how much

To estimate the magnitude of these managerial componentsof the menu costs consider the following In an average chainthere is at least one executive of merchandising who devotesmost of hisher time to pricing decisions In addition there areup to three senior managers who would deal with pricing andto whom category managers report There are also ten-to-twelvecategory managers who are responsible for setting prices on allthe products within their category An additional two-to-fourpeople spend full time handling the implementation of pricechanges across retail outlets coordinating the printing and deliv-ery of price tags and handling pricing problems in the systemAnother ve-to-seven workers gather the data on competitorsrsquoprices and analyse both the competitorsrsquo data and the storersquos ownscanner data to put it in a form useable by managers makingpricing decisions Thus in total there are about 21ndash27 peopleworking at the corporate headquarters on price change decisionsAssuming $150000 as the average annual salary of the executiveof merchandising and senior managers $100000 for categorymanagers and $50000 for the rest the chainwide managerialcost falls in the neighborhood of $23ndash$29 million a year whichseems a substantial amount However note that these pricing de-cision are made for the entire chain and therefore the costs perstore are signicantly less especially for the larger chains Forexample using $29 million as the upper bound the additionalannual menu cost per store for Chains AndashD which on averageoperate about 400 stores each averages about $7250 which ismuch lower than expected and is due to the centralization of theprice change decisions in the chains we study17

signed to save the costs of corporate headquarter managerial time spent on pricechange decisions the ESL company did not measure this component of menucosts The estimates reported in this section are based on the information receivedfrom the ESL company executives

17 A decentralization of the price change process say by allowing the store-level managers to make price change decisions can change these gures tremen-dously For example consider the following thought experiment conducted using

QUARTERLY JOURNAL OF ECONOMICS808

Our menu cost measures also do not include the cost ofchanging prices of direct store delivery (DSD) products Theseproducts are almost completely handled by manufacturers in-cluding stocking monitoring inventories and setting and chang-ing prices18 We have data on the weekly frequency of pricechanges of DSD products in Chain E In an average week thereare 174 price changes of DSD products which is about 10 percentof the supermarketrsquos total weekly price changes Using the costof changing the price of a regular product $133 (see Section IVfor details) the annual cost of changing prices of the DSD prod-ucts in this chain roughly equals $1203419 Our menu cost mea-sures do not include these gures since we do not have similardata for the other chains20

III6 Total Menu Costs

The total annual menu costs reported for each chain perstore are listed in the last row of Table III As the table indicatesthe menu costs range from $91416 to $114188 for an average of$105887 per store per year21 Note that these menu cost mea-

the average annual per store gures for Chains AndashD Suppose that the supermar-ket chains decentralize the price change process by hiring for each store only one-quarter of the price change managing team while at the same time they com-pletely eliminate the corporate level team The resulting annual menu cost perstore would be $830887 ( 5 $105887 1 $725000) which would dwarf any of themeasurable menu cost gures we report in this study Even if the average storeonly hired just the merchandising manager at the annual cost of $150000 itwould still incur annual managerial cost of about $255887 ( 5 $105887 1$150000) In other words such a trivial decentralization would double the store-level menu costs This would indeed make the cost of price change decisions themost important component of menu cost

18 DSD products usually are high-volume fast-moving or perishable prod-ucts such as milk soda eggs bread dairy snacks etc In the chains we studyabout 10ndash20 percent of the products are of a DSD type but that share may reachas much as 40 percent of the products carried [Direct Store Delivery Work Groupet al 1995]

19 The process of changing prices of DSD and of regular products is similarBut with DSD products there are additional costs of the time spent on driving tothe store parking and setting up the price change process at each store

20 Our measures of menu cost also do not incorporate the cost of informingconsumers about price changes which can take a variety of forms such as newspa-per ads and inserts TV and radio ads in-store promotion signs etc Finally wehave no data on lost customer goodwill and damaged reputation caused by dis-crepancies between price tag and cash register [Okun 1981 Carlton and Perloff1994 Haddock and McChesney 1994]

21 The variation in the menu costs across the chains is mostly due to wagerate and labor-efciency variations Also note that since the supermarket chainsin our sample are similar in the size of their stores carry similar sets of productsand follow similar processes of price change and price change decisions it is rea-sonable to believe that the chains incur similar types of costs Therefore as notedunderneath Table III these menu cost measures are computed by replacing theunreported gures by the averages of the available values from the other chains

THE MAGNITUDE OF MENU COSTS 809

sures include only the components we could accurately measurein dollar terms which are discussed in subsections III1ndashIII4

IV ITEM PRICING LAWS AND MENU COSTS

In this section we provide evidence on the menu costs for anadditional chain (Chain E) which unlike the other four chainsoperates in a state with an item pricing law The most importantaspect of item pricing laws is that they require a price tag on eachindividual item sold not just on the shelf which is what the otherfour chains in our sample do For example the item pricing lawin Connecticut requires that the grocers ldquoshall mark or cause tobe marked each consumer commodity which bears a UniversalProduct Code with its retail pricerdquo 22 From a menu cost perspec-tive the requirement of posting prices on every item (in additionto the shelf price tag) introduces additional costs in the processof changing prices

Although most of the steps involved in changing prices arethe same for both types of chains stores that are subject to itempricing laws have to undertake additional steps to obey this law23

The labor cost component of menu costs in Chain E totals $75127a year of which $49710 is the cost of the labor time spent onchanging the prices of individual items $3234 is the cost of thelabor time spent on shelf tag replacements and $22183 is thecost of the labor time spent on sign changes (see Table III)24 Anadditional $44168 is spent annually putting prices on new itemsas they are brought to the shelves Although we do not includethis last gure in our menu cost measures because we do not haveinformation on how much of it is due to price change activity andhow much due to just pricingmdashthese costs are clearly a directconsequence of the item pricing law The printing and deliverycost of price tags and price signs are $7644 and the mistake

22 Public Act No 75ndash391 An Act Concerning Pricing of Consumer Merchan-dise [Public Acts of the State of Connecticut 1975 Vol 1 p 390]

23 These steps which are in addition to the regular steps undertaken toreplace price tags on the shelves include (1) obtaining item price tags (2) settingup workstations (3) locating the product (4) removing an item from the shelf (5)removing old price tag (6) setting marking gun (7) applying new price tag and(8) returning the item back to the shelf

24 Since we do not have a measure of the cost of labor time spent on signchanges and the cost of in-store managerial supervision time for this chain weuse the average of the chains that report them (A and D) Note also that thehourly wage rate of $907 paid by Chain E is lower than the hourly wage of about$1400ndash$2000 paid by Chains AndashD

QUARTERLY JOURNAL OF ECONOMICS810

25 Further note that the chains with smaller menu costs are likely tochange their prices more frequently which suggests that the gures of the totalannual menu costs understate the differences between Chain E and the otherchains Indeed despite the large difference in the menu cost per price change thetotal annual menu costs per store for Chain E ($109036) are more comparable tothose of Chains AndashD ($105887)

26 In calculations that follow we use industry averages because (1) thechains did not share this proprietary information with us and (2) we were re-quired to keep the identity of these chains condential as some of these numbersare detailed enough to enable some readers to identify the chains under study

costs are $20799 These gures along with the amount of $5466for the cost of in-store managerial supervision time yield totalannual menu costs of $109036 per store

Although the magnitude of the total annual menu costs seemsimilar to the other four chains note that the average weeklyfrequency of price changes in Chain E is only 1578 which is only403 ( 5 15783916) percent of the price changes made by theother four chains Thus the average menu cost per price changefor Chain E is $133 (see Table IV last row) In contrast the corre-sponding gures for Chains AndashD average $052 Hence the menucosts per price change incurred by the supermarket chain facingitem pricing laws are more than two and a half times the amountincurred by chains that are not subject to this law25 Overallthese ndings suggest that legal restrictions of the type of itempricing laws can have a signicant impact on the menu costs in-curred by sellers

V SIGNIFICANCE OF THE MENU COSTS

The next natural question to ask is how important are thesecosts To address this question we (1) provide several relativemeasures of the menu costs (2) discuss the effect of the menucosts on supermarketsrsquo price change activity and (3) discuss mac-roeconomic implications by relating our ndings to the existingtheoretical models of menu costs In each case we provide addi-tional evidence to help assess the importance of these menu costs

V1 Relative Measures of the Menu Costs

In order to assess the relative magnitude of the menu costsreported in Section IV we now present the menu cost gures rela-tive to the average store-level revenues and net prot margins26

In addition we present the menu cost gures per price changeThe annual average revenues of a large U S supermarket

chain of the type and size included in our sample is $15052716

per store27 According to the second row of Table IV the ratio ofmenu costs to revenues for Chains AndashD ranges between 061ndash076percent averaging 070 percent28 We relate the size of thesegures to the existing theoretical menu cost models in sub-section V3

Net prot margin which measures the revenues minus allcosts is approximately 1ndash3 percent of revenues for these chains[Montgomery 1994] so we use 2 percent as a working averageThe reason for the low prot rate in this industry is the intensecompetition [Calatone et al 1989] especially at the regional level[Chevalier 1995] which has been increasing since the early 1990s[Progressive Grocer November 1992 p 50] It follows that theaverage store protability for these chains equals $301054 peryear Therefore the ratio of total menu cost to net margin forChains AndashD ranges between 304ndash379 percent for an average of352 percent Thus the menu costs we report in this study repre-sent a signicant share of supermarketsrsquo prots

Another way to look at the menu cost gures we report is toexpress them relative to the frequency of price changes In thelast row of Table IV we present the menu cost gures per pricechange for each chain As the table indicates the cost of changinga price in Chains AndashD ranges between $046ndash$068 for an averageof $052 For Chain E the gure is substantially larger $133 perprice change29 These gures are lower than the estimated cost of

27 This is the average of two different estimates $12945432 and$17160000 The source of the rst gure is internal record of a supermarketchain of the type and size studied here The second gure comes from Supermar-ket Business [1993 p 52]

28 We also measured the menu costs in terms of controllable operating ex-penses (which are the portion of costs that the retailer has direct control over andtherefore are often the costs that the retailer is most focused on managing) andgross margins (which measure the supermarket revenues minus direct cost of theproducts it sells) We nd that the menu costs comprise 313 percent of controlla-ble operating expenses and 281 percent of gross margins at these chains on aver-age Finally if we measure the menu costs relative to the number of productscarried per store (about 25000) then we nd that the menu costs per productaverage $423 for Chains AndashD See Table IV and its footnotes for details

29 We can also try to express the menu cost gures relative to the numberof individual items sold by these chains each year (Note the difference betweennumber of products carried and number of items sold As an example a TartarControl Crest 8oz would be considered a product carried and 300 units of themsold per year would be considered number of items sold) Using $170 as the aver-age price of all the products sold we nd that the menu cost per item sold for thefour chains is in the range of $00103ndash$00129 for an average of $00119 (see TableIV second to last row) To see the relative magnitude of these gures note thataccording to Berkowitz Kerin and Rudelius [1986 p 319] the goal of the super-market chains of the type we study ldquo is to make 1 penny of prot on each dollarof salesrdquo Thus menu cost per item sold when adjusted for the average price

THE MAGNITUDE OF MENU COSTS 813

$200ndash$300 per price change reported by Slade [1996a] Thereare several possible reasons for this (1) our menu cost gures arebased on actual measurements of the resources that go into theprice change process whereas she estimates menu costs econo-metrically as model coefcients using a mix of store-level priceand aggregate cost data (2) we cover 25000 products that thesupermarkets carry rather than a single product category (3) ourmenu cost gures do not include all components of menu costsand (4) there could be differences in wage rates that may be im-portant given the signicance of the labor cost component inmenu costs

V2 The Effect of Menu Costs on the Price Change Activity of theSupermarkets

In this section we present evidence which suggests that thesemenu costs may be forming a barrier to price change activity Tobegin with consider the effect of the item pricing law on the pricechange activity of Chain E The data on the weekly frequency ofprice changes in each chain are displayed in the last two rows ofTable I According to these gures the average weekly frequencyof price changes in Chain E is only 1578 Thus on average ChainE changes the prices of only 631 percent of its products eachweek In contrast the average weekly frequency of price changesat Chains AndashD ranges from 3223 to 4316 for the four-chain aver-age of 3916 price changes weekly So Chains AndashD change priceson 1289 to 1726 percent of their products each week yielding afour-chain average of 1566 percent Thus Chain E which facesthe item pricing law changes prices only about one-third timesas frequently as do Chains AndashD30

Moreover within Chain E there are 400 products that areexempt from the item pricing law and thereby face lower menucosts We nd that there are an average of 83 weekly pricechanges for these products yielding 21 percent of these productschanging prices So within Chain E they change prices over threetimes as frequently for products with lower menu costs than for

roughly equals one-half of their target net prot per item which seemssubstantial

30 However note that our comparison of the two types of chains may not becompletely ceteris paribus because these stores are located in different states andtherefore there may be other chain-specic factors (in addition to item pricinglaws) that distinguish these stores We do not have any specic information onthese differences We do know however that the stores in these chains are similarin size and carry similar sets of products

QUARTERLY JOURNAL OF ECONOMICS814

the products with higher menu costs Note that this nding is onthe price change activity within the same chain offering almost anatural experiment on the impact of menu costs on the chainrsquospricing behavior Hence we provide evidence both across chainsas well as across products within a chain that as the costs ofchanging price go up the frequency of price changes goes downThus the menu costs we nd are signicant enough to affect thechainrsquos price change practice

We also have additional evidence from Chains A B and Dabout these menu costs being a barrier to certain price changesand it is summarized in Table V According to the Price Manage-ment Department of Chain A the chain experiences cost in-creases on 860 products in an average week to which it wouldlike to react with a price increase31 However on average 22 per-cent of these price increases are not implemented immediatelybecause the cost of changing prices for these products is too highto make it economically worthwhile Figures of the same magni-tude were reported by other chains For example Chain D experi-ences cost increases for 961 products in an average week Out ofthese the chain adjusts prices of only 633 products The re-maining 34 percent of the prices are left unadjusted because ofthe menu costs Similarly Chain B nds it economically ineffi-cient to adjust prices of 508 ie 30 percent of its products eachweek because of menu costs This provides additional evidencethat the menu costs incurred by these chains are preventing priceadjustments to some costs changes leading to price rigidities ofthe products involved32 Note that although we do not have simi-lar data for Chain E we would expect signicantly lower num-bers on this measure at that chain These gures also suggest anupper bound on the benet of complete price exibility under thecurrent pricing practice of weekly price adjustments Howeverif new technologies (eg ESL systems) and new pricing prac-tices (eg a decentralization of the price change decisions) are

31 Our data contain information only on the frequency of cost increasesAlthough it is more than likely that the supermarkets are experiencing cost de-creases as well our data set contained no information on such decreases

32 Menu costs may even be playing a role in the observed movement towardpricing strategies that rely on fewer price changes such as EDLP [Blattberg andNeslin 1989 Lattin and Ortmeyer 1991 Marketing News April 13 1992 p 8]According to Progressive Grocer [November 1992 p 50] ldquoA growing number ofoperators say they have switched from high-low pricing [to EDLP] They cite theinefciencies of making frequent price changes rdquo Similarly Hoch Dreze andPurk [1994 p 16] state that EDLP lowers operating costs by lowering ldquo in-store labor costs because of less frequent changeovers in special displaysrdquo

adopted allowing a fundamental change in the way the pricingmechanism is currently set the managers could consider morefrequent price change activity (eg multiple times each week) asmenu costs go down

In this paper we measure the menu costs at the chainsrsquo cur-rent level of price change activity It may be worthwhile to specu-late on the shape of the cost function relating menu costs to thefrequency of price changes by assessing how these costs wouldchange if the price change activity were to increase or to decreaseIt seems likely that many of the costs we report in this paper will(approximately) change linearly with additional price changeswithin the current range of price changes the chains are under-taking (plus or minus perhaps a thousand per week) For ex-ample the labor costs associated with changing a shelf price tagcosts of verifying price changes and the costs of mistakes oc-curring during this process all increase linearly with the fre-quency of price changes This is because most of the time-consuming steps involved in the price change process must berepeated each time an additional shelf price tag is changed (seeTable II) Further we were unable to nd many tasks that gener-ated signicant returns to scale It is unclear what cost savingsare available if the price change activity drops substantially be-

QUARTERLY JOURNAL OF ECONOMICS816

low the levels it is at now Clearly if price changes were nearzero or done less frequently than weekly (say monthly) therecould be major differences in these costs

What is less clear is how these costs would change at moreextreme levels of price change activity With less frequent pricechanges the menu costs could probably be reduced signicantlyalthough the cost of deciding what prices to set initially and thecost of putting the initial shelf price tags would still remain as alower bound of the menu cost However for achieving more priceexibility by changing prices more frequently (ie multiple timeseach week) substantial changes must be undertaken At presentthe supermarket chains are set up to make the majority of theirprice changes on a weekly basis with the appropriate systems inplace to make this process most efcient For example in orderto save costs and to have higher quality price tags (eg withcolor more details greater clarity glossy etc) the chains oftensend new price tag requests to a printing shop which takes threedays to print and deliver the labels to each store Then giventhe large number of price changes taking place and the goals ofminimizing customer disruptions and labor costs (such as over-time pay) and coordinating with advertised price promotions theprices are changed in the store over a two-to-three-day period (seeTable VI) The combination of these schedule and built-in lags isacceptable under the current practice of changing prices weeklybut would have to be adjusted dramatically to allow for signifi-cantly more frequent price changes on a regular basis

Perhaps even more imposing are the costs of changing themanagerial costs associated with the current weekly system ofprice changes The process of pricing at this organizational levelis not a self-contained activity taking place in isolation from otheroperations of the supermarket management Rather it is a partof a larger system of business decisions and operations The cur-rent process of operations (such as data collection and theiranalysis management meetings coordination of the decisionsacross functional areas etc) is set up to function on a weeklybasis33 Further these management accounting and logisticssystems are currently built around a tremendous amount of in-

35 If the supermarket chains indeed restructure the entire price change pro-cess and begin to change prices much more frequently (say two-to-three times aweek) on a regular basis then the shape of this cost function could change in anunpredictable way

V3 Relating Our Findings to the Existing Theoretical Models ofMenu Costs

In order to assess the magnitude of these menu cost guresin the context of the existing theoretical menu cost literatureconsider the following calculation experiments done within theframework of two theoretical menu cost models Blanchard andKiyotaki [1987] study a general equilibrium menu cost modelwith monopolistic competition and with unit elasticity of aggre-gate demand with respect to real money balances According totheir calculations menu costs of the magnitude of 008 percent ofrevenues which they consider ldquovery smallrdquo may be sufcient toprevent adjustment of prices Ball and Romer [1990] conductsimilar calculations in the framework of a model with imperfectcompetition and menu costs They nd that for plausible markupand labor elasticity parameter values menu costs needed to pre-vent price adjustment are 070 percent of revenues which as theysuggest are nonnegligible For smaller menu costs eg 004 per-cent of the revenue which Ball and Romer consider ldquotrivialrdquo im-plausibly large values of markup and labor elasticity parametersare needed to prevent price adjustment to monetary shocks

According to the gures in Table IV the reported menu costto revenues ratio for Chains AndashD averages 070 percent rangingfrom 061 percent to 076 percent These are signicantly largerthan the ldquotrivialrdquo 004 or 008 percent gures mentioned abovesuggesting that the menu cost gures we nd here are nontrivialFurther under the model and parameter values considered byBlanchard and Kiyotaki [1987] the menu cost gures we nd arehigher than the theoretical minimum needed to form a barrier toprice adjustments Under the model and parameter values con-sidered by Ball and Romer [1990] the reported menu costreve-nue ratio for all but one chain reaches or crosses the theoreticalthreshold of 070 needed to form a barrier to price adjustmentsThe existence of numerous unmeasured menu cost componentsdiscussed in subsection III5 also raises the possibility that theactual menu costs incurred by these chains are signicantlyhigher than that threshold This suggests that the menu costs wereport may be large enough to form a barrier to nominal priceadjustments when interpreted in the context of these models

An issue of interest in this literature is time-dependent ver-sus state-dependent pricing rules (see for example Caplin andLeahy [1991]) The evidence from our data set on the timing of

THE MAGNITUDE OF MENU COSTS 819

price changes suggests that the price change decisions in thesesupermarkets have a strong time-dependent price-setting ele-ment36 For example according to Table VI the prices in Chain Aare changed weekly according to the following schedule the pricechanges of general merchandise that is advertised is done Satur-day nights grocery and produce prices are changed Sundaynights the rest of the general merchandise prices are changed onMonday nights and the prices of advertised grocery items arechanged on Tuesday nights Thus as the gures in Table VI indi-cate over 96 percent of the price changes are done during Sundayand Monday nights However this does not imply that state-dependent pricing rules are unimportant Even if price changesacross product categories follow a prescheduled weekly time ta-ble the prices of which products to change is likely to be a state-dependent decision For example it could depend on changes insupply and demand conditions such as competitorsrsquo price changedecisions Indeed Levy Dutta and Bergen [1996] use retailstore-level orange juice price and cost data to demonstrate thatthe extent of price response to cost shocks that is the extent ofprice rigidity may depend on the nature of supply shocks37

We do not want to overstate the usefulness of our data fordirectly addressing the issue of monetary nonneutrality On onehand authors such as Caplin and Spulber [1987] have demon-strated that under certain conditions individual price rigiditymay not be sufcient for aggregate price rigidity but unfortu-nately our data do not speak directly to this issue38 On the otherhand authors such as Akerlof and Yellen [1985] Mankiw [1985]Parkin [1986] and Caplin and Leahy [1997] have shown that even

36 Danziger [1983] Caballero [1989] and Ball and Mankiw [1994] suggestthat time-dependent price adjustment of the type documented here can be optimalif the cost of gathering information about the state exceeds the cost of making theprice adjustment itself

37 We also considered the possibility of convexities in the cost of changingprices Our data do not suggest many convexities since the labor time spent inthe price tag change process the cost of printing and delivering price tags andin-store supervision time do not change with the size of a price change The onlymeasurable component of menu costs that could be convex is the cost of mistakesmade the larger the price change the higher the probability of a customer notic-ing the mistake and the larger the amount required to be refunded as compensa-tion Among the unmeasured components of menu cost the cost of corporatemanagerial time may increase with the size of a price change because larger pricechanges may require more serious consideration

38 Also see Balke and Wynne [1996] and Bryan and Cecchetti [1996] Sincewe do not have measures of how menu costs change over time our data also havelittle to say about time variation in menu costs or about the relationship betweenmenu costs and ination which during the period of the data collection (1991ndash1992) averaged about 3 percent annually

QUARTERLY JOURNAL OF ECONOMICS820

small menu costs can be relevant since they may be sufcient togenerate substantial aggregate nominal rigidity and thus largebusiness cycles Therefore as Blinder [1994] Kashyap [1995]and Slade [1996a] emphasize it is important to search for directevidence that such costs are indeed present at the micro level Bydirectly identifying documenting and measuring the magnitudeof menu costs at the store level we are taking an important stepin that direction

VI CONCLUSION AND FUTURE RESEARCH

Our main contribution is that we provide direct microeco-nomic evidence on the actual magnitude of menu costs for fourlarge U S retail supermarket chains The annual menu costs perstore at these chains average $105887 comprising 070 percentof revenues 352 percent of net prot margins and $052 perprice change on average

Further we provide evidence which suggests that thesemenu costs may be forming a barrier to price changes Specifi-cally we show that (1) supermarket chains not subject to itempricing law change prices two and a half times more frequentlythan the chain that is subject to the law (2) within the chain thatis subject to the item pricing law they change prices over threetimes as frequently for products that are exempt from this lawthan for the products which are subject to this law and (3) wend that these chains do not adjust prices of up to one-third ofthe products for which they face cost increases because of menucost considerations

When we relate these ndings to the existing theoreticalmodels of menu costs we conclude that the magnitude of menucosts we nd is large enough to be capable of having macroeco-nomic signicance Specically when considered in the context ofthe theoretical menu cost models of Blanchard and Kiyotaki[1987] and Ball and Romer [1990] we nd that the menu costgures we report are ldquonontrivialrdquo and their relative magnitudescross the minimum theoretical threshold needed to form a barrierto price adjustments

Despite the high relative magnitude of the marginal cost ofchanging price that we found the data still indicate frequentweekly price changes This is because of the high marginal bene-t of changing price which is due to the erce competition foundin the retail supermarket industry That marginal benets may

THE MAGNITUDE OF MENU COSTS 821

outweigh the marginal costs of changing prices in this industryhowever does not rule out the possibility that menu costs of themagnitude we nd here can create substantial nominal rigidityin other industries or markets In less competitive industries andmarkets menu costs of the type and magnitude we documenthere are likely to have a bigger impact on the frequency of priceadjustment and consequently on the degree of price rigidity

At a minimum the direct dollar measures of menu costs wereport here can be used as a starting point for future research onmeasuring their magnitude in other industries and establish-ments We anticipate that these menu costs will be similar inother markets which rely on posted prices (such as drugstoresdepartment stores etc) because the steps involved in the pricechange process are likely to be similar What may differ are thefrequency of price changes and the labor wage rates at thesestores For example since supermarket chains change thousandsof prices each week the total annual menu costs incurred bythese chains per store are likely to be high in comparison to otherretail formats such as chain drugstores or department storesThere are however a variety of industries for which the stepsinvolved in changing prices would be signicantly different fromthose reported in our study For example business-to-businesssales which often rely on a sales force will require changes in thelist price sheets changes in the instructions to the sales forcewhich may include education and discussion with the salespeoplein the company and so forth These business-to-business pricesalso often have more complex pricing schemes including quantitydiscounts bundling and individually negotiated prices As an-other example the composition of the cost of changing the news-stand prices of magazines [Cecchetti 1986] or the prices ofproducts sold through catalogs [Kashyap 1995] are different frommany of the menu cost components we discuss here Further thending that a centralization of pricing decisions makes the store-level managerial component of menu cost relatively small sug-gests that the managerial menu costs likely are highest insettings where price change decisions are decentralized Thus fu-ture empirical work should look at menu cost and its compositionin a variety of other industries markets and products with bothcentralized as well as decentralized price change decisions in or-der to see whether the magnitude of these costs can be general-ized and benchmarks can be established Further there aretechnological changes taking place in this and other industries

that promise to alter the structure of menu costs which deserveattention At the theoretical level our ndings suggest that it maybe worthwhile to explore models which incorporate the idea ofitem pricing laws as an additional component of menu costs

THE MAGNITUDE OF MENU COSTS 825

price law average $105887 annually per store In relative termsthese menu costs comprise 070 percent of revenues 352 percentof net margins and $052 per price change on average

Our second major contribution in this paper is providing evi-dence that these menu costs can form a barrier to price changeactivity at these chains offering direct support for the relation-ship between menu costs and store-level individual price rigidityWe present three types of evidence that these menu costs form abarrier to price change activity at these rms First we contrastthe price change activity of a chain that operates in a state withan item pricing law with the rst four chains that operate instates not subject to such laws Item pricing laws require that aseparate price tag be placed on each individual item sold (in addi-tion to the shelf price tag) We show that the average menu costper price change for the chain subject to the item pricing law is$133 over two and a half times the corresponding gure for theother four chains ($052) These larger menu costs lead to verydifferent levels of price change activity by these chains Specifi-cally the four supermarket chains that are not subject to itempricing laws on average change prices on 156 percent of the prod-ucts they carry each week In contrast the chain that is subjectto the item pricing law (and therefore faces higher menu costs)changes prices on only 63 percent of the products it carrieswhich is less than half the average of the other four chains

Second within the chain facing the item pricing law thereare 400 products that are exempt from this law and thereby facelower menu costs For these products the chain each weekchanges the prices of 21 percent of the products on average whichis over three times more frequently than for products subject tothe item pricing law Third we provide evidence from the super-market chains that the menu costs they incur form a barrier tocertain cost-based price adjustments Specically we show thatthe chains not subject to item pricing laws each week experiencecost increases on about 800ndash1000 products they sell Yet they ad-just prices of only about 70ndash80 percent of these products Theremaining 20ndash30 percent of the prices are not adjusted immedi-ately because the existing menu costs make the necessary priceadjustment unprotable Considering all three of these ndingstogether we conclude that menu costs can indeed affect pricechange activity at the level of the individual rmmdashoffering directevidence that these menu costs are relevant to marginal pricechange decisions Finally on a related macroeconomic issue we

THE MAGNITUDE OF MENU COSTS 793

provide empirical evidence which suggests that the price changeprocess in these supermarket chains has a strong time-dependent element

Relating our ndings to the existing theoretical models weconclude that the magnitude of the menu costs we nd is largeenough to be capable of having macroeconomic signicance Firstrecall that according to the studies of Akerlof and Yellen [1985]Mankiw [1985] Parkin [1986] and Caplin and Leahy [1997] evensmall menu costs can be relevant since they may be sufcient togenerate substantial aggregate nominal rigidity and thus largebusiness cycles Second when considered in the context of thetheoretical menu cost models of Blanchard and Kiyotaki [1987]and Ball and Romer [1990] we nd that the menu cost gureswe report are ldquonontrivialrdquo and their relative magnitudes cross theminimum theoretical threshold needed to form a barrier to priceadjustments

Although in this paper we provide direct measurements ofthe marginal costs associated with changing prices it should bementioned that there are still many aspects of menu costs we areunable to measure In particular we do not provide measure-ments of the marginal benets associated with changing priceswhich can be signicant [Lieberman and Zilberfarb 1985 She-shinski and Weiss 1977] At the local level this industry is ex-tremely competitive [Calatone et al 1989 Progressive GrocerNovember 1992 p 50 Chevalier 1995] In such a competitive in-dustry the benets of frequently changing prices can be high asunmatched price cuts or consumer perceptions of higher pricescan lead to signicant losses in sales5 This helps explain whydespite the magnitude of the menu costs we found we still ob-serve frequent weekly price change activity by the chains westudy For example stores change an average of 15ndash16 percent oftheir prices each week Also they seem to adjust the prices of70ndash80 percent of the products for which they experience cost in-creases6 Thus although we have evidence that the menu costswe report in this study clearly matter in the sense that they cre-

5 Also changing prices frequently can make it more difcult for customersto compare prices of branded items across supermarkets because of higher searchcosts [Carlton 1986] which is valuable for creating differentiation between retailoutlets [Bergen Dutta and Shugan 1996]

6 This level of price change activity is similar to that found in other studiesof U S supermarket prices [Dutta Bergen and Levy 1995] although the pricereaction to cost changes can be signicantly more rigid depending on the natureof the cost changes the retailer faces [Levy Dutta and Bergen 1996]

QUARTERLY JOURNAL OF ECONOMICS794

ate some barriers to price change activity at these retail super-market outlets they are not large enough to prevent a signicantshare of prices to adjust

The paper is organized as follows In Section II we describethe data In Section III we discuss the price change process insupermarket chains and report absolute measures of menu costsIn Section IV we assess the effect of item pricing laws on menucosts In Section V we discuss the signicance of the menu costsWe end with conclusions and suggestions for future research

II DATA DESCRIPTION

The data come from a company that sells electronic shelf la-bel (ESL) systems These systems allow retailers to change theshelf prices electronically from a central computer (where pricechanges are actually done) via a wireless communication systemand thus reduce the physical costs and lead times currently asso-ciated with changing shelf prices In order to sell the product thecompany needed to validate what the existing costs of changingshelf prices were in supermarket chains ie the existing levelsof menu costs This company received access from corporate head-quarters at each of the ve chains in our sample to go to represen-tative stores and carefully record the exact steps involved in theprice change process These studies considered the entire pricechange process in each chain For this detailed work-ow sche-matics of each task in the price change process was developedObservations of the process were conducted in multiple stores ofthe chains (at least two representative stores for each chain) toverify its accuracy Information received from chainsrsquo pricing sys-tems in-store observations in-store counts and in-store timemeasurements (with a stopwatch) were used to determine thevolume of work performed in each step of the tasks weekly fre-quency of each step performed and the exact amount of time re-quired to perform one unit of the work After computing the totalhours per task this information was reconciled with the knowntotal hours spent each week This allowed for task level compari-sons for the existing and test process Each study required hun-dreds of man-hours to create The studies were conducted duringthe years 1991ndash1992

Although we believe the menu costs reported in this paperare representative of menu costs in the U S supermarket indus-try we should mention that they may be biased upward because

THE MAGNITUDE OF MENU COSTS 795

the rm had an incentive to overestimate the magnitude of themenu costs in order to sell the ESL system We think howeverthat the menu cost measures we report in this paper are not sub-ject to signicant biases of this sort for a number of reasonsFirst the ESL people measured and documented all price changeactivities jointly with the supermarket employees using the wagegures provided by the supermarket management Second timeand motion measurements of the type used for measuring themenu costs we report here are routinely done by supermarketchains themselves in order to assess the efciency of their pricechange processes The supermarket managers compared theirgures to the ESL company gures and found them to be similarFurther these gures were presented to upper management ofthese chains and were found to be representative of their coststructures In fact the validity of the menu cost measures con-structed by the ESL company was never disputed If there wasany disagreement between the ESL company and the supermar-ket chains it was about the size of the savings the ESL systemwould provide not about the accuracy of the menu cost measure-ments7 Further we looked at these reports and searched for g-ures that could be biased upward There were a few such as lossof goodwill costs and inventory holding costs and to be on theconservative side we did not include them in our measures ofmenu costs Thus we only report gures for which we could seeno upward bias Finally note that the menu cost gures we reportare clearly biased downward because we were unable to measurein dollar terms several components of menu costs and thus theyare not included in our gures (see subsection III5 for details)

Table I displays some general information about the super-market chains we study their pricing strategy and informationabout the frequency of weekly price changes the stores under-take The chains involved in this study are all large U S super-market chains from different regions in the United Statesranging from the Northeast to the West Coast and operating anaverage of 400 stores each At the request of these retailers wewill keep the companies in this study anonymous but they areall large multistore chains that seem reasonably representativeof large supermarket chains currently selling in the United

7 Indeed four out of the ve chains included in our sample have purchasedESL systems three of the four actually purchased multiple systems (between twoand twenty systems) and Chain E is considering buying 50 more

a HL (HighLow) and EDLP (Every Day Low Price) refer to the general pricing strategy followed by theretail chain Under the EDLP strategy the retailer rsquos prices are low for extended periods of time and there-fore it will offer fewer promotional sales or discounts Under the HL pricing strategy in contrast the retail-errsquos prices are higher and the retailer tends to offer more frequent discounts through sales and promotionsSee the text for more details

b The share of products for which prices change on an average week is the ratio of number of pricechanges per store per week to 25000 The latter is the average number of products carried per store eachweek

States These chains are similar in the variety selection andquantity of the products they carry Supermarket chains of thistype make up $310146666000 in total annual sales which is863 percent of total supermarket chain sales in 1992 [Supermar-ket Business 1993] so the chains in our sample are representativeof a major class of the retail grocery trade

According to the second row in Table I the number of weeklyprice changes in Chains AndashD ranges from 3223 to 4316 for anaverage of 3916 per store8 The variation in the number of weeklyprice changes across the chains is due in large part to their choiceof pricing strategy Chains A and B follow a highlow (HL) pricestrategy while Chains C and D follow an everyday-low-pricestrategy (EDLP) Under the EDLP strategy the retailerrsquos pricesare low for an extended period of time and therefore it will offerfewer promotional sales or discounts Under the HL pricing strat-egy in contrast the retailerrsquos prices are higher and the retailertends to offer more frequent discounts through sales and promo-tions The pricing strategy therefore will have an effect on thefrequency of price changes observed In particular we would ex-

THE MAGNITUDE OF MENU COSTS 797

pect EDLP stores to have less frequent price changes in compari-son to the HL stores Indeed according to Table I Chains A andB tend to have a higher number of weekly price changes (4278and 4316 respectively) than Chains C and D (3846 and 3223respectively)

Supermarkets of the size we study tend to carry around25000 different items on a regular basis9 The last row in thetable presents the share of the 25000 products for which the su-permarket chains change their prices in a period of one weekThe average share for the four chains is 1566 percent

III ABSOLUTE MEASURES OF MENU COSTS

There are four components of menu costs that we are able tomeasure in dollar terms10 These are (1) the cost of labor requiredto change the shelf price tags (2) the cost of printing and deliv-ering new price tags (3) the cost of mistakes made during theprocess of changing prices and (4) the cost of in-store supervisiontime spent on implementing price changes

III1 Costs of the Labor Required to Change Shelf Prices

Figure I displays an overview of the steps involved in chang-ing prices at Chain A There are three main components in thelabor costs incurred by the chains (a) labor cost of tag changepreparation (b) labor cost of the tag change itself and (c) laborcost of verifying whether the price changes are done correctlywhich include tag change verication in-store resolution of pricemistakes and zone and corporate resolution of price mistakes11

9 The supermarkets often have about 40000 UPC codes in their computerdatabase records but internal studies undertaken by the ESL company indicatethat the supermarkets usually carry no more than 25000 products at any giventime The extra UPC codes are for seasonal or promotional sizes and packages ofproducts and for discontinued products

10 In this paper we only report measures of the marginal cost of changingprices The costs of putting a price tag for the rst time and other costs thatwould be included in the average cost are not included in the gures we reportOnly when discussing Chain E which is the chain subject to item pricing lawsdid we face the issue of cost of pricing (at the rst time) versus the cost of changinga price Since there was no clear way of separating the two types of costs thereported cost gure ($44168 in the second paragraph of Section IV) was excludedaltogether from our calculations Also see footnote 13

11 For a detailed description of the entire price change process with ow-charts documenting the specic steps undertaken in this process and the exacttime period spent on each step see Levy Dutta Bergen and Venable [1997] Anappendix reporting computational details are contained in a working paper ver-sion of this paper which is available upon request

FIGURE IOverview of the Price Change Process

POS denotes Point of Sale and refers to the cash register or the database itis connected to or both For information on the various steps undertaken in eachstage of the price change process and the amount of the labor time spent on mosttime-consuming steps see Table II

Standard price tag changes which include the steps outlined onthe left-hand side of Figure I make up the majority of pricechanges in these chains Some price changes also require addi-tional price signs to be placed at different locations in the storesuch as on an end of aisle display or near the shelf12 These sign

12 These are usually related to the product being on promotion feature ad-vertising display or in-store sale such as ldquomanagerrsquos specialrdquo ldquotodayrsquos specialrdquoetc The steps involved in making sign changes are similar to price changes Themain differences are that (i) the time required for each of the steps in sign changes

changes add to the menu costs and they are outlined on theright-hand side of Figure I the sign change preparation actualsign changes and sign change verication boxes The bottom twoboxes in Figure I are additional menu costs related to the extrasteps taken in these stores to make sure the tag and sign changeshave been done correctly13

Table II lists each stage of the price change process the totalamount of time spent on each stage each week on average andthe number of tasks performed In addition the table identiessome of the main tasks performed in each stage as well as thefour most time-consuming tasks in each stage To compute thetotal labor time used in changing prices on a weekly basis wecombine the data collected through in-store time and motion ob-servations with information on the volume of products for whichprices are changed These weekly hours are multiplied by thewage rates (adjusted for fringe benets) of the employees used inthe price change process to get the total costs of labor required tochange prices

For the four supermarket chains in our study the total an-nual labor cost of changing the shelf price tags ranges from$40027 to $61414 per store for an average of $52084 (see therst row in Table III making up about 49 percent of the totalmenu costs on average The labor cost of changing the price signsrange from $16411 to $27955 per store for an average of$22183 (see the second row in Table III) making up almost 21percent of the menu costs on average Thus for the four super-market chains the total annual menu costs associated with thelabor required to change prices (shelf price tags and price signscombined) range from $62210 to $81703 per store for an annualaverage of $74267 This is the single largest component of themenu costs we report in this study making up about 701 percentof the total menu costs for these chains on average This shouldnot be surprising given that the most signicant portion of retail

are longer because they are in less standard locations and (ii) there are fewersign changes than standard shelf price tag changes

13 The menu cost measures we report do not include the cost of changingprices in cases where items are moved from shelf to shelf or where shelf space isreallocated by increasing the shelf space for some products at the expense of oth-ers However they do include the cost of pricing new products when they are rstintroduced While this could bias the menu cost measures upward since it reallycaptures the cost of pricing rather than the cost of changing price the size of thisbias is marginal due to the small number of new products For example accordingto ESL company executives the number of new products introduced at thesechains each week ranges from 20 to 100 approximately In comparison to the num-ber of products for which prices are changed each week (3223ndash4316) the biasis negligible

grocery operating expenses is labor costs [Hoch Dreze andPurk 1994]14

III2 Costs of Printing and Delivering New Price Tags

There are direct costs associated with printing and deliv-ering the price and sign tags The order must be recorded andprocessed at the chain sent to the printer recorded and pro-cessed at the printer printed packaged and then delivered toeach store The cost per tag is usually quite low $0017 per tagat Chain A which includes stock costs of $00118 per tag impres-sion and data center operator costs of $00037 per tag and mailroom handling costs of $00010 per tag There are however manyprice changes undertaken each week In total the costs of print-ing and delivering the price and sign tags range from $3048 to$10018 averaging $6014 per store per year (see Table III)These costs comprise less than 6 percent of the total menu costswe report

III3 Costs of Mistakes Made in the Process of Changing Prices

Despite the labor put into checking to make sure that theprice changes are done correctly there are still many price mis-takes that are not caught until customers discover them through-out the week and these mistakes impose costs on the chainClearly the costs associated with these errors must be consideredwhen deciding whether to change prices or not and therefore area relevant dimension of menu costs These mistakes can occur sooften that they were a feature of a Dateline segment on U Ssupermarket chains [NBC April 1992] and an article in MoneyMagazine [April 1993] Both the Money Magazine article andGoodstein [1994] report that on average 10 percent of the prod-ucts they examined had price mistakes A more recent study bythe Federal Trade Commission [1996] reports a total error rate ofabout 5 percent

The menu costs associated with these mistakes include lost

14 Our measure of labor cost may overstate the true costs of changing pricesif supermarkets hoard labor to save hiring and ring costs However this is notlikely to be the case for several reasons First the labor costs of changing priceswe report are based on actual measurements of the minimum amount of time andlabor required to accomplish the task rather than on the number of employeeshired to change prices at the store Second the adjustment in the amount of laboris usually done through hours worked which makes cost of hiring and ring lessrelevant And third the workers on the oor are routinely moved from task totask according to the need These tasks include stocking cleaning price changingcustomer service etc The workers employed by supermarket chains are alwaysbusy and so the opportunity cost of changing price is not zero Therefore laborhoarding is not likely to be an important factor in our measurements

QUARTERLY JOURNAL OF ECONOMICS806

cashier time to correct the errors scan guarantee refunds andinventory mistakes associated with incorrect price tags15 Lostcashier time is measured here in terms of wage payments Scanguarantee refunds are additional price reductions beyond the er-ror or additional items given away for free because of the mis-take Finally the inventory mistakes costs we report include onlythe cost of stockouts which occur when shelf price is lower thanintended

The mistake costs were available at Chains A C and D andthey range from $19135 to $20692 for an average of $20140 perstore annually (see Table III) These costs are the second largestcomponent of menu costs in our study comprising about 19 per-cent of the total

III4 Costs of In-Store Supervision Time Spent on ImplementingPrice Changes

Managers at the store level spend time overseeing imple-menting and troubleshooting the price change process OnlyChains A and B had a measure of the menu costs associated withthis in-store supervision time and both of these came from a self-reported number of hours spent on changing prices by the manag-ers at these chains The hours spent on changing prices were thesame across the chains approximately ve hours per week Thusthe menu costs for in-store supervision time came to $4241 and$6692 per store annually for Chains A and B respectively (seeTable III) These costs comprise less than 6 percent of the totalmenu costs we report in this paper However notice that thesemeasures do not include the cost of the management time spenton price change decisions made at corporate headquarters whichis discussed next

III5 Components of Menu Costs We Are Unable to Measure inDollar Terms

Our data set does not contain the exact dollar measures ofsome menu cost components One such component is the cost ofcorporate management time spent on price change decisions16 In

15 Other likely costs of price mistakes that we do not consider explicitlybecause we are unable to measure them in dollar terms are legal problems (whenthe scanner price is higher than the shelf price) loss in customer goodwill anddecreased protability (when the scanner price is lower than the shelf price)

16 It has been suggested that the cost of managerial decisions is one of themost important components of menu cost See for example Ball and Mankiw[1994] Kashyap [1995] and Meltzer [1995] Since the ESL system was not de-

THE MAGNITUDE OF MENU COSTS 807

the supermarket chains we study prices are generally set at cor-porate headquarters in a weekly meeting where the manager incharge of setting prices looks at a variety of information including(a) any manufacturer wholesale price changes promotions andother related issues (b) past sales for this product and (c) com-petitorsrsquo prices Based on this information and on discussionswith other managers the price-setting manager decides whetherto change prices and if so by how much

To estimate the magnitude of these managerial componentsof the menu costs consider the following In an average chainthere is at least one executive of merchandising who devotesmost of hisher time to pricing decisions In addition there areup to three senior managers who would deal with pricing andto whom category managers report There are also ten-to-twelvecategory managers who are responsible for setting prices on allthe products within their category An additional two-to-fourpeople spend full time handling the implementation of pricechanges across retail outlets coordinating the printing and deliv-ery of price tags and handling pricing problems in the systemAnother ve-to-seven workers gather the data on competitorsrsquoprices and analyse both the competitorsrsquo data and the storersquos ownscanner data to put it in a form useable by managers makingpricing decisions Thus in total there are about 21ndash27 peopleworking at the corporate headquarters on price change decisionsAssuming $150000 as the average annual salary of the executiveof merchandising and senior managers $100000 for categorymanagers and $50000 for the rest the chainwide managerialcost falls in the neighborhood of $23ndash$29 million a year whichseems a substantial amount However note that these pricing de-cision are made for the entire chain and therefore the costs perstore are signicantly less especially for the larger chains Forexample using $29 million as the upper bound the additionalannual menu cost per store for Chains AndashD which on averageoperate about 400 stores each averages about $7250 which ismuch lower than expected and is due to the centralization of theprice change decisions in the chains we study17

signed to save the costs of corporate headquarter managerial time spent on pricechange decisions the ESL company did not measure this component of menucosts The estimates reported in this section are based on the information receivedfrom the ESL company executives

17 A decentralization of the price change process say by allowing the store-level managers to make price change decisions can change these gures tremen-dously For example consider the following thought experiment conducted using

QUARTERLY JOURNAL OF ECONOMICS808

Our menu cost measures also do not include the cost ofchanging prices of direct store delivery (DSD) products Theseproducts are almost completely handled by manufacturers in-cluding stocking monitoring inventories and setting and chang-ing prices18 We have data on the weekly frequency of pricechanges of DSD products in Chain E In an average week thereare 174 price changes of DSD products which is about 10 percentof the supermarketrsquos total weekly price changes Using the costof changing the price of a regular product $133 (see Section IVfor details) the annual cost of changing prices of the DSD prod-ucts in this chain roughly equals $1203419 Our menu cost mea-sures do not include these gures since we do not have similardata for the other chains20

III6 Total Menu Costs

The total annual menu costs reported for each chain perstore are listed in the last row of Table III As the table indicatesthe menu costs range from $91416 to $114188 for an average of$105887 per store per year21 Note that these menu cost mea-

the average annual per store gures for Chains AndashD Suppose that the supermar-ket chains decentralize the price change process by hiring for each store only one-quarter of the price change managing team while at the same time they com-pletely eliminate the corporate level team The resulting annual menu cost perstore would be $830887 ( 5 $105887 1 $725000) which would dwarf any of themeasurable menu cost gures we report in this study Even if the average storeonly hired just the merchandising manager at the annual cost of $150000 itwould still incur annual managerial cost of about $255887 ( 5 $105887 1$150000) In other words such a trivial decentralization would double the store-level menu costs This would indeed make the cost of price change decisions themost important component of menu cost

18 DSD products usually are high-volume fast-moving or perishable prod-ucts such as milk soda eggs bread dairy snacks etc In the chains we studyabout 10ndash20 percent of the products are of a DSD type but that share may reachas much as 40 percent of the products carried [Direct Store Delivery Work Groupet al 1995]

19 The process of changing prices of DSD and of regular products is similarBut with DSD products there are additional costs of the time spent on driving tothe store parking and setting up the price change process at each store

20 Our measures of menu cost also do not incorporate the cost of informingconsumers about price changes which can take a variety of forms such as newspa-per ads and inserts TV and radio ads in-store promotion signs etc Finally wehave no data on lost customer goodwill and damaged reputation caused by dis-crepancies between price tag and cash register [Okun 1981 Carlton and Perloff1994 Haddock and McChesney 1994]

21 The variation in the menu costs across the chains is mostly due to wagerate and labor-efciency variations Also note that since the supermarket chainsin our sample are similar in the size of their stores carry similar sets of productsand follow similar processes of price change and price change decisions it is rea-sonable to believe that the chains incur similar types of costs Therefore as notedunderneath Table III these menu cost measures are computed by replacing theunreported gures by the averages of the available values from the other chains

THE MAGNITUDE OF MENU COSTS 809

sures include only the components we could accurately measurein dollar terms which are discussed in subsections III1ndashIII4

IV ITEM PRICING LAWS AND MENU COSTS

In this section we provide evidence on the menu costs for anadditional chain (Chain E) which unlike the other four chainsoperates in a state with an item pricing law The most importantaspect of item pricing laws is that they require a price tag on eachindividual item sold not just on the shelf which is what the otherfour chains in our sample do For example the item pricing lawin Connecticut requires that the grocers ldquoshall mark or cause tobe marked each consumer commodity which bears a UniversalProduct Code with its retail pricerdquo 22 From a menu cost perspec-tive the requirement of posting prices on every item (in additionto the shelf price tag) introduces additional costs in the processof changing prices

Although most of the steps involved in changing prices arethe same for both types of chains stores that are subject to itempricing laws have to undertake additional steps to obey this law23

The labor cost component of menu costs in Chain E totals $75127a year of which $49710 is the cost of the labor time spent onchanging the prices of individual items $3234 is the cost of thelabor time spent on shelf tag replacements and $22183 is thecost of the labor time spent on sign changes (see Table III)24 Anadditional $44168 is spent annually putting prices on new itemsas they are brought to the shelves Although we do not includethis last gure in our menu cost measures because we do not haveinformation on how much of it is due to price change activity andhow much due to just pricingmdashthese costs are clearly a directconsequence of the item pricing law The printing and deliverycost of price tags and price signs are $7644 and the mistake

22 Public Act No 75ndash391 An Act Concerning Pricing of Consumer Merchan-dise [Public Acts of the State of Connecticut 1975 Vol 1 p 390]

23 These steps which are in addition to the regular steps undertaken toreplace price tags on the shelves include (1) obtaining item price tags (2) settingup workstations (3) locating the product (4) removing an item from the shelf (5)removing old price tag (6) setting marking gun (7) applying new price tag and(8) returning the item back to the shelf

24 Since we do not have a measure of the cost of labor time spent on signchanges and the cost of in-store managerial supervision time for this chain weuse the average of the chains that report them (A and D) Note also that thehourly wage rate of $907 paid by Chain E is lower than the hourly wage of about$1400ndash$2000 paid by Chains AndashD

QUARTERLY JOURNAL OF ECONOMICS810

25 Further note that the chains with smaller menu costs are likely tochange their prices more frequently which suggests that the gures of the totalannual menu costs understate the differences between Chain E and the otherchains Indeed despite the large difference in the menu cost per price change thetotal annual menu costs per store for Chain E ($109036) are more comparable tothose of Chains AndashD ($105887)

26 In calculations that follow we use industry averages because (1) thechains did not share this proprietary information with us and (2) we were re-quired to keep the identity of these chains condential as some of these numbersare detailed enough to enable some readers to identify the chains under study

costs are $20799 These gures along with the amount of $5466for the cost of in-store managerial supervision time yield totalannual menu costs of $109036 per store

Although the magnitude of the total annual menu costs seemsimilar to the other four chains note that the average weeklyfrequency of price changes in Chain E is only 1578 which is only403 ( 5 15783916) percent of the price changes made by theother four chains Thus the average menu cost per price changefor Chain E is $133 (see Table IV last row) In contrast the corre-sponding gures for Chains AndashD average $052 Hence the menucosts per price change incurred by the supermarket chain facingitem pricing laws are more than two and a half times the amountincurred by chains that are not subject to this law25 Overallthese ndings suggest that legal restrictions of the type of itempricing laws can have a signicant impact on the menu costs in-curred by sellers

V SIGNIFICANCE OF THE MENU COSTS

The next natural question to ask is how important are thesecosts To address this question we (1) provide several relativemeasures of the menu costs (2) discuss the effect of the menucosts on supermarketsrsquo price change activity and (3) discuss mac-roeconomic implications by relating our ndings to the existingtheoretical models of menu costs In each case we provide addi-tional evidence to help assess the importance of these menu costs

V1 Relative Measures of the Menu Costs

In order to assess the relative magnitude of the menu costsreported in Section IV we now present the menu cost gures rela-tive to the average store-level revenues and net prot margins26

In addition we present the menu cost gures per price changeThe annual average revenues of a large U S supermarket

chain of the type and size included in our sample is $15052716

per store27 According to the second row of Table IV the ratio ofmenu costs to revenues for Chains AndashD ranges between 061ndash076percent averaging 070 percent28 We relate the size of thesegures to the existing theoretical menu cost models in sub-section V3

Net prot margin which measures the revenues minus allcosts is approximately 1ndash3 percent of revenues for these chains[Montgomery 1994] so we use 2 percent as a working averageThe reason for the low prot rate in this industry is the intensecompetition [Calatone et al 1989] especially at the regional level[Chevalier 1995] which has been increasing since the early 1990s[Progressive Grocer November 1992 p 50] It follows that theaverage store protability for these chains equals $301054 peryear Therefore the ratio of total menu cost to net margin forChains AndashD ranges between 304ndash379 percent for an average of352 percent Thus the menu costs we report in this study repre-sent a signicant share of supermarketsrsquo prots

Another way to look at the menu cost gures we report is toexpress them relative to the frequency of price changes In thelast row of Table IV we present the menu cost gures per pricechange for each chain As the table indicates the cost of changinga price in Chains AndashD ranges between $046ndash$068 for an averageof $052 For Chain E the gure is substantially larger $133 perprice change29 These gures are lower than the estimated cost of

27 This is the average of two different estimates $12945432 and$17160000 The source of the rst gure is internal record of a supermarketchain of the type and size studied here The second gure comes from Supermar-ket Business [1993 p 52]

28 We also measured the menu costs in terms of controllable operating ex-penses (which are the portion of costs that the retailer has direct control over andtherefore are often the costs that the retailer is most focused on managing) andgross margins (which measure the supermarket revenues minus direct cost of theproducts it sells) We nd that the menu costs comprise 313 percent of controlla-ble operating expenses and 281 percent of gross margins at these chains on aver-age Finally if we measure the menu costs relative to the number of productscarried per store (about 25000) then we nd that the menu costs per productaverage $423 for Chains AndashD See Table IV and its footnotes for details

29 We can also try to express the menu cost gures relative to the numberof individual items sold by these chains each year (Note the difference betweennumber of products carried and number of items sold As an example a TartarControl Crest 8oz would be considered a product carried and 300 units of themsold per year would be considered number of items sold) Using $170 as the aver-age price of all the products sold we nd that the menu cost per item sold for thefour chains is in the range of $00103ndash$00129 for an average of $00119 (see TableIV second to last row) To see the relative magnitude of these gures note thataccording to Berkowitz Kerin and Rudelius [1986 p 319] the goal of the super-market chains of the type we study ldquo is to make 1 penny of prot on each dollarof salesrdquo Thus menu cost per item sold when adjusted for the average price

THE MAGNITUDE OF MENU COSTS 813

$200ndash$300 per price change reported by Slade [1996a] Thereare several possible reasons for this (1) our menu cost gures arebased on actual measurements of the resources that go into theprice change process whereas she estimates menu costs econo-metrically as model coefcients using a mix of store-level priceand aggregate cost data (2) we cover 25000 products that thesupermarkets carry rather than a single product category (3) ourmenu cost gures do not include all components of menu costsand (4) there could be differences in wage rates that may be im-portant given the signicance of the labor cost component inmenu costs

V2 The Effect of Menu Costs on the Price Change Activity of theSupermarkets

In this section we present evidence which suggests that thesemenu costs may be forming a barrier to price change activity Tobegin with consider the effect of the item pricing law on the pricechange activity of Chain E The data on the weekly frequency ofprice changes in each chain are displayed in the last two rows ofTable I According to these gures the average weekly frequencyof price changes in Chain E is only 1578 Thus on average ChainE changes the prices of only 631 percent of its products eachweek In contrast the average weekly frequency of price changesat Chains AndashD ranges from 3223 to 4316 for the four-chain aver-age of 3916 price changes weekly So Chains AndashD change priceson 1289 to 1726 percent of their products each week yielding afour-chain average of 1566 percent Thus Chain E which facesthe item pricing law changes prices only about one-third timesas frequently as do Chains AndashD30

Moreover within Chain E there are 400 products that areexempt from the item pricing law and thereby face lower menucosts We nd that there are an average of 83 weekly pricechanges for these products yielding 21 percent of these productschanging prices So within Chain E they change prices over threetimes as frequently for products with lower menu costs than for

roughly equals one-half of their target net prot per item which seemssubstantial

30 However note that our comparison of the two types of chains may not becompletely ceteris paribus because these stores are located in different states andtherefore there may be other chain-specic factors (in addition to item pricinglaws) that distinguish these stores We do not have any specic information onthese differences We do know however that the stores in these chains are similarin size and carry similar sets of products

QUARTERLY JOURNAL OF ECONOMICS814

the products with higher menu costs Note that this nding is onthe price change activity within the same chain offering almost anatural experiment on the impact of menu costs on the chainrsquospricing behavior Hence we provide evidence both across chainsas well as across products within a chain that as the costs ofchanging price go up the frequency of price changes goes downThus the menu costs we nd are signicant enough to affect thechainrsquos price change practice

We also have additional evidence from Chains A B and Dabout these menu costs being a barrier to certain price changesand it is summarized in Table V According to the Price Manage-ment Department of Chain A the chain experiences cost in-creases on 860 products in an average week to which it wouldlike to react with a price increase31 However on average 22 per-cent of these price increases are not implemented immediatelybecause the cost of changing prices for these products is too highto make it economically worthwhile Figures of the same magni-tude were reported by other chains For example Chain D experi-ences cost increases for 961 products in an average week Out ofthese the chain adjusts prices of only 633 products The re-maining 34 percent of the prices are left unadjusted because ofthe menu costs Similarly Chain B nds it economically ineffi-cient to adjust prices of 508 ie 30 percent of its products eachweek because of menu costs This provides additional evidencethat the menu costs incurred by these chains are preventing priceadjustments to some costs changes leading to price rigidities ofthe products involved32 Note that although we do not have simi-lar data for Chain E we would expect signicantly lower num-bers on this measure at that chain These gures also suggest anupper bound on the benet of complete price exibility under thecurrent pricing practice of weekly price adjustments Howeverif new technologies (eg ESL systems) and new pricing prac-tices (eg a decentralization of the price change decisions) are

31 Our data contain information only on the frequency of cost increasesAlthough it is more than likely that the supermarkets are experiencing cost de-creases as well our data set contained no information on such decreases

32 Menu costs may even be playing a role in the observed movement towardpricing strategies that rely on fewer price changes such as EDLP [Blattberg andNeslin 1989 Lattin and Ortmeyer 1991 Marketing News April 13 1992 p 8]According to Progressive Grocer [November 1992 p 50] ldquoA growing number ofoperators say they have switched from high-low pricing [to EDLP] They cite theinefciencies of making frequent price changes rdquo Similarly Hoch Dreze andPurk [1994 p 16] state that EDLP lowers operating costs by lowering ldquo in-store labor costs because of less frequent changeovers in special displaysrdquo

adopted allowing a fundamental change in the way the pricingmechanism is currently set the managers could consider morefrequent price change activity (eg multiple times each week) asmenu costs go down

In this paper we measure the menu costs at the chainsrsquo cur-rent level of price change activity It may be worthwhile to specu-late on the shape of the cost function relating menu costs to thefrequency of price changes by assessing how these costs wouldchange if the price change activity were to increase or to decreaseIt seems likely that many of the costs we report in this paper will(approximately) change linearly with additional price changeswithin the current range of price changes the chains are under-taking (plus or minus perhaps a thousand per week) For ex-ample the labor costs associated with changing a shelf price tagcosts of verifying price changes and the costs of mistakes oc-curring during this process all increase linearly with the fre-quency of price changes This is because most of the time-consuming steps involved in the price change process must berepeated each time an additional shelf price tag is changed (seeTable II) Further we were unable to nd many tasks that gener-ated signicant returns to scale It is unclear what cost savingsare available if the price change activity drops substantially be-

low the levels it is at now Clearly if price changes were nearzero or done less frequently than weekly (say monthly) therecould be major differences in these costs

What is less clear is how these costs would change at moreextreme levels of price change activity With less frequent pricechanges the menu costs could probably be reduced signicantlyalthough the cost of deciding what prices to set initially and thecost of putting the initial shelf price tags would still remain as alower bound of the menu cost However for achieving more priceexibility by changing prices more frequently (ie multiple timeseach week) substantial changes must be undertaken At presentthe supermarket chains are set up to make the majority of theirprice changes on a weekly basis with the appropriate systems inplace to make this process most efcient For example in orderto save costs and to have higher quality price tags (eg withcolor more details greater clarity glossy etc) the chains oftensend new price tag requests to a printing shop which takes threedays to print and deliver the labels to each store Then giventhe large number of price changes taking place and the goals ofminimizing customer disruptions and labor costs (such as over-time pay) and coordinating with advertised price promotions theprices are changed in the store over a two-to-three-day period (seeTable VI) The combination of these schedule and built-in lags isacceptable under the current practice of changing prices weeklybut would have to be adjusted dramatically to allow for signifi-cantly more frequent price changes on a regular basis

Perhaps even more imposing are the costs of changing themanagerial costs associated with the current weekly system ofprice changes The process of pricing at this organizational levelis not a self-contained activity taking place in isolation from otheroperations of the supermarket management Rather it is a partof a larger system of business decisions and operations The cur-rent process of operations (such as data collection and theiranalysis management meetings coordination of the decisionsacross functional areas etc) is set up to function on a weeklybasis33 Further these management accounting and logisticssystems are currently built around a tremendous amount of in-

33 For example the data are analyzed and presented to managers on Mon-day and Tuesday with meetings set for Thursday and Friday to make pricingdecisions for the next week in coordination with all other business functions ofthe chain

35 If the supermarket chains indeed restructure the entire price change pro-cess and begin to change prices much more frequently (say two-to-three times aweek) on a regular basis then the shape of this cost function could change in anunpredictable way

V3 Relating Our Findings to the Existing Theoretical Models ofMenu Costs

In order to assess the magnitude of these menu cost guresin the context of the existing theoretical menu cost literatureconsider the following calculation experiments done within theframework of two theoretical menu cost models Blanchard andKiyotaki [1987] study a general equilibrium menu cost modelwith monopolistic competition and with unit elasticity of aggre-gate demand with respect to real money balances According totheir calculations menu costs of the magnitude of 008 percent ofrevenues which they consider ldquovery smallrdquo may be sufcient toprevent adjustment of prices Ball and Romer [1990] conductsimilar calculations in the framework of a model with imperfectcompetition and menu costs They nd that for plausible markupand labor elasticity parameter values menu costs needed to pre-vent price adjustment are 070 percent of revenues which as theysuggest are nonnegligible For smaller menu costs eg 004 per-cent of the revenue which Ball and Romer consider ldquotrivialrdquo im-plausibly large values of markup and labor elasticity parametersare needed to prevent price adjustment to monetary shocks

According to the gures in Table IV the reported menu costto revenues ratio for Chains AndashD averages 070 percent rangingfrom 061 percent to 076 percent These are signicantly largerthan the ldquotrivialrdquo 004 or 008 percent gures mentioned abovesuggesting that the menu cost gures we nd here are nontrivialFurther under the model and parameter values considered byBlanchard and Kiyotaki [1987] the menu cost gures we nd arehigher than the theoretical minimum needed to form a barrier toprice adjustments Under the model and parameter values con-sidered by Ball and Romer [1990] the reported menu costreve-nue ratio for all but one chain reaches or crosses the theoreticalthreshold of 070 needed to form a barrier to price adjustmentsThe existence of numerous unmeasured menu cost componentsdiscussed in subsection III5 also raises the possibility that theactual menu costs incurred by these chains are signicantlyhigher than that threshold This suggests that the menu costs wereport may be large enough to form a barrier to nominal priceadjustments when interpreted in the context of these models

An issue of interest in this literature is time-dependent ver-sus state-dependent pricing rules (see for example Caplin andLeahy [1991]) The evidence from our data set on the timing of

THE MAGNITUDE OF MENU COSTS 819

price changes suggests that the price change decisions in thesesupermarkets have a strong time-dependent price-setting ele-ment36 For example according to Table VI the prices in Chain Aare changed weekly according to the following schedule the pricechanges of general merchandise that is advertised is done Satur-day nights grocery and produce prices are changed Sundaynights the rest of the general merchandise prices are changed onMonday nights and the prices of advertised grocery items arechanged on Tuesday nights Thus as the gures in Table VI indi-cate over 96 percent of the price changes are done during Sundayand Monday nights However this does not imply that state-dependent pricing rules are unimportant Even if price changesacross product categories follow a prescheduled weekly time ta-ble the prices of which products to change is likely to be a state-dependent decision For example it could depend on changes insupply and demand conditions such as competitorsrsquo price changedecisions Indeed Levy Dutta and Bergen [1996] use retailstore-level orange juice price and cost data to demonstrate thatthe extent of price response to cost shocks that is the extent ofprice rigidity may depend on the nature of supply shocks37

We do not want to overstate the usefulness of our data fordirectly addressing the issue of monetary nonneutrality On onehand authors such as Caplin and Spulber [1987] have demon-strated that under certain conditions individual price rigiditymay not be sufcient for aggregate price rigidity but unfortu-nately our data do not speak directly to this issue38 On the otherhand authors such as Akerlof and Yellen [1985] Mankiw [1985]Parkin [1986] and Caplin and Leahy [1997] have shown that even

36 Danziger [1983] Caballero [1989] and Ball and Mankiw [1994] suggestthat time-dependent price adjustment of the type documented here can be optimalif the cost of gathering information about the state exceeds the cost of making theprice adjustment itself

37 We also considered the possibility of convexities in the cost of changingprices Our data do not suggest many convexities since the labor time spent inthe price tag change process the cost of printing and delivering price tags andin-store supervision time do not change with the size of a price change The onlymeasurable component of menu costs that could be convex is the cost of mistakesmade the larger the price change the higher the probability of a customer notic-ing the mistake and the larger the amount required to be refunded as compensa-tion Among the unmeasured components of menu cost the cost of corporatemanagerial time may increase with the size of a price change because larger pricechanges may require more serious consideration

38 Also see Balke and Wynne [1996] and Bryan and Cecchetti [1996] Sincewe do not have measures of how menu costs change over time our data also havelittle to say about time variation in menu costs or about the relationship betweenmenu costs and ination which during the period of the data collection (1991ndash1992) averaged about 3 percent annually

QUARTERLY JOURNAL OF ECONOMICS820

small menu costs can be relevant since they may be sufcient togenerate substantial aggregate nominal rigidity and thus largebusiness cycles Therefore as Blinder [1994] Kashyap [1995]and Slade [1996a] emphasize it is important to search for directevidence that such costs are indeed present at the micro level Bydirectly identifying documenting and measuring the magnitudeof menu costs at the store level we are taking an important stepin that direction

VI CONCLUSION AND FUTURE RESEARCH

Our main contribution is that we provide direct microeco-nomic evidence on the actual magnitude of menu costs for fourlarge U S retail supermarket chains The annual menu costs perstore at these chains average $105887 comprising 070 percentof revenues 352 percent of net prot margins and $052 perprice change on average

Further we provide evidence which suggests that thesemenu costs may be forming a barrier to price changes Specifi-cally we show that (1) supermarket chains not subject to itempricing law change prices two and a half times more frequentlythan the chain that is subject to the law (2) within the chain thatis subject to the item pricing law they change prices over threetimes as frequently for products that are exempt from this lawthan for the products which are subject to this law and (3) wend that these chains do not adjust prices of up to one-third ofthe products for which they face cost increases because of menucost considerations

When we relate these ndings to the existing theoreticalmodels of menu costs we conclude that the magnitude of menucosts we nd is large enough to be capable of having macroeco-nomic signicance Specically when considered in the context ofthe theoretical menu cost models of Blanchard and Kiyotaki[1987] and Ball and Romer [1990] we nd that the menu costgures we report are ldquonontrivialrdquo and their relative magnitudescross the minimum theoretical threshold needed to form a barrierto price adjustments

Despite the high relative magnitude of the marginal cost ofchanging price that we found the data still indicate frequentweekly price changes This is because of the high marginal bene-t of changing price which is due to the erce competition foundin the retail supermarket industry That marginal benets may

THE MAGNITUDE OF MENU COSTS 821

outweigh the marginal costs of changing prices in this industryhowever does not rule out the possibility that menu costs of themagnitude we nd here can create substantial nominal rigidityin other industries or markets In less competitive industries andmarkets menu costs of the type and magnitude we documenthere are likely to have a bigger impact on the frequency of priceadjustment and consequently on the degree of price rigidity

At a minimum the direct dollar measures of menu costs wereport here can be used as a starting point for future research onmeasuring their magnitude in other industries and establish-ments We anticipate that these menu costs will be similar inother markets which rely on posted prices (such as drugstoresdepartment stores etc) because the steps involved in the pricechange process are likely to be similar What may differ are thefrequency of price changes and the labor wage rates at thesestores For example since supermarket chains change thousandsof prices each week the total annual menu costs incurred bythese chains per store are likely to be high in comparison to otherretail formats such as chain drugstores or department storesThere are however a variety of industries for which the stepsinvolved in changing prices would be signicantly different fromthose reported in our study For example business-to-businesssales which often rely on a sales force will require changes in thelist price sheets changes in the instructions to the sales forcewhich may include education and discussion with the salespeoplein the company and so forth These business-to-business pricesalso often have more complex pricing schemes including quantitydiscounts bundling and individually negotiated prices As an-other example the composition of the cost of changing the news-stand prices of magazines [Cecchetti 1986] or the prices ofproducts sold through catalogs [Kashyap 1995] are different frommany of the menu cost components we discuss here Further thending that a centralization of pricing decisions makes the store-level managerial component of menu cost relatively small sug-gests that the managerial menu costs likely are highest insettings where price change decisions are decentralized Thus fu-ture empirical work should look at menu cost and its compositionin a variety of other industries markets and products with bothcentralized as well as decentralized price change decisions in or-der to see whether the magnitude of these costs can be general-ized and benchmarks can be established Further there aretechnological changes taking place in this and other industries

that promise to alter the structure of menu costs which deserveattention At the theoretical level our ndings suggest that it maybe worthwhile to explore models which incorporate the idea ofitem pricing laws as an additional component of menu costs

provide empirical evidence which suggests that the price changeprocess in these supermarket chains has a strong time-dependent element

Relating our ndings to the existing theoretical models weconclude that the magnitude of the menu costs we nd is largeenough to be capable of having macroeconomic signicance Firstrecall that according to the studies of Akerlof and Yellen [1985]Mankiw [1985] Parkin [1986] and Caplin and Leahy [1997] evensmall menu costs can be relevant since they may be sufcient togenerate substantial aggregate nominal rigidity and thus largebusiness cycles Second when considered in the context of thetheoretical menu cost models of Blanchard and Kiyotaki [1987]and Ball and Romer [1990] we nd that the menu cost gureswe report are ldquonontrivialrdquo and their relative magnitudes cross theminimum theoretical threshold needed to form a barrier to priceadjustments

Although in this paper we provide direct measurements ofthe marginal costs associated with changing prices it should bementioned that there are still many aspects of menu costs we areunable to measure In particular we do not provide measure-ments of the marginal benets associated with changing priceswhich can be signicant [Lieberman and Zilberfarb 1985 She-shinski and Weiss 1977] At the local level this industry is ex-tremely competitive [Calatone et al 1989 Progressive GrocerNovember 1992 p 50 Chevalier 1995] In such a competitive in-dustry the benets of frequently changing prices can be high asunmatched price cuts or consumer perceptions of higher pricescan lead to signicant losses in sales5 This helps explain whydespite the magnitude of the menu costs we found we still ob-serve frequent weekly price change activity by the chains westudy For example stores change an average of 15ndash16 percent oftheir prices each week Also they seem to adjust the prices of70ndash80 percent of the products for which they experience cost in-creases6 Thus although we have evidence that the menu costswe report in this study clearly matter in the sense that they cre-

5 Also changing prices frequently can make it more difcult for customersto compare prices of branded items across supermarkets because of higher searchcosts [Carlton 1986] which is valuable for creating differentiation between retailoutlets [Bergen Dutta and Shugan 1996]

6 This level of price change activity is similar to that found in other studiesof U S supermarket prices [Dutta Bergen and Levy 1995] although the pricereaction to cost changes can be signicantly more rigid depending on the natureof the cost changes the retailer faces [Levy Dutta and Bergen 1996]

ate some barriers to price change activity at these retail super-market outlets they are not large enough to prevent a signicantshare of prices to adjust

The paper is organized as follows In Section II we describethe data In Section III we discuss the price change process insupermarket chains and report absolute measures of menu costsIn Section IV we assess the effect of item pricing laws on menucosts In Section V we discuss the signicance of the menu costsWe end with conclusions and suggestions for future research

II DATA DESCRIPTION

The data come from a company that sells electronic shelf la-bel (ESL) systems These systems allow retailers to change theshelf prices electronically from a central computer (where pricechanges are actually done) via a wireless communication systemand thus reduce the physical costs and lead times currently asso-ciated with changing shelf prices In order to sell the product thecompany needed to validate what the existing costs of changingshelf prices were in supermarket chains ie the existing levelsof menu costs This company received access from corporate head-quarters at each of the ve chains in our sample to go to represen-tative stores and carefully record the exact steps involved in theprice change process These studies considered the entire pricechange process in each chain For this detailed work-ow sche-matics of each task in the price change process was developedObservations of the process were conducted in multiple stores ofthe chains (at least two representative stores for each chain) toverify its accuracy Information received from chainsrsquo pricing sys-tems in-store observations in-store counts and in-store timemeasurements (with a stopwatch) were used to determine thevolume of work performed in each step of the tasks weekly fre-quency of each step performed and the exact amount of time re-quired to perform one unit of the work After computing the totalhours per task this information was reconciled with the knowntotal hours spent each week This allowed for task level compari-sons for the existing and test process Each study required hun-dreds of man-hours to create The studies were conducted duringthe years 1991ndash1992

Although we believe the menu costs reported in this paperare representative of menu costs in the U S supermarket indus-try we should mention that they may be biased upward because

THE MAGNITUDE OF MENU COSTS 795

the rm had an incentive to overestimate the magnitude of themenu costs in order to sell the ESL system We think howeverthat the menu cost measures we report in this paper are not sub-ject to signicant biases of this sort for a number of reasonsFirst the ESL people measured and documented all price changeactivities jointly with the supermarket employees using the wagegures provided by the supermarket management Second timeand motion measurements of the type used for measuring themenu costs we report here are routinely done by supermarketchains themselves in order to assess the efciency of their pricechange processes The supermarket managers compared theirgures to the ESL company gures and found them to be similarFurther these gures were presented to upper management ofthese chains and were found to be representative of their coststructures In fact the validity of the menu cost measures con-structed by the ESL company was never disputed If there wasany disagreement between the ESL company and the supermar-ket chains it was about the size of the savings the ESL systemwould provide not about the accuracy of the menu cost measure-ments7 Further we looked at these reports and searched for g-ures that could be biased upward There were a few such as lossof goodwill costs and inventory holding costs and to be on theconservative side we did not include them in our measures ofmenu costs Thus we only report gures for which we could seeno upward bias Finally note that the menu cost gures we reportare clearly biased downward because we were unable to measurein dollar terms several components of menu costs and thus theyare not included in our gures (see subsection III5 for details)

Table I displays some general information about the super-market chains we study their pricing strategy and informationabout the frequency of weekly price changes the stores under-take The chains involved in this study are all large U S super-market chains from different regions in the United Statesranging from the Northeast to the West Coast and operating anaverage of 400 stores each At the request of these retailers wewill keep the companies in this study anonymous but they areall large multistore chains that seem reasonably representativeof large supermarket chains currently selling in the United

7 Indeed four out of the ve chains included in our sample have purchasedESL systems three of the four actually purchased multiple systems (between twoand twenty systems) and Chain E is considering buying 50 more

a HL (HighLow) and EDLP (Every Day Low Price) refer to the general pricing strategy followed by theretail chain Under the EDLP strategy the retailer rsquos prices are low for extended periods of time and there-fore it will offer fewer promotional sales or discounts Under the HL pricing strategy in contrast the retail-errsquos prices are higher and the retailer tends to offer more frequent discounts through sales and promotionsSee the text for more details

b The share of products for which prices change on an average week is the ratio of number of pricechanges per store per week to 25000 The latter is the average number of products carried per store eachweek

States These chains are similar in the variety selection andquantity of the products they carry Supermarket chains of thistype make up $310146666000 in total annual sales which is863 percent of total supermarket chain sales in 1992 [Supermar-ket Business 1993] so the chains in our sample are representativeof a major class of the retail grocery trade

According to the second row in Table I the number of weeklyprice changes in Chains AndashD ranges from 3223 to 4316 for anaverage of 3916 per store8 The variation in the number of weeklyprice changes across the chains is due in large part to their choiceof pricing strategy Chains A and B follow a highlow (HL) pricestrategy while Chains C and D follow an everyday-low-pricestrategy (EDLP) Under the EDLP strategy the retailerrsquos pricesare low for an extended period of time and therefore it will offerfewer promotional sales or discounts Under the HL pricing strat-egy in contrast the retailerrsquos prices are higher and the retailertends to offer more frequent discounts through sales and promo-tions The pricing strategy therefore will have an effect on thefrequency of price changes observed In particular we would ex-

THE MAGNITUDE OF MENU COSTS 797

pect EDLP stores to have less frequent price changes in compari-son to the HL stores Indeed according to Table I Chains A andB tend to have a higher number of weekly price changes (4278and 4316 respectively) than Chains C and D (3846 and 3223respectively)

Supermarkets of the size we study tend to carry around25000 different items on a regular basis9 The last row in thetable presents the share of the 25000 products for which the su-permarket chains change their prices in a period of one weekThe average share for the four chains is 1566 percent

III ABSOLUTE MEASURES OF MENU COSTS

There are four components of menu costs that we are able tomeasure in dollar terms10 These are (1) the cost of labor requiredto change the shelf price tags (2) the cost of printing and deliv-ering new price tags (3) the cost of mistakes made during theprocess of changing prices and (4) the cost of in-store supervisiontime spent on implementing price changes

III1 Costs of the Labor Required to Change Shelf Prices

Figure I displays an overview of the steps involved in chang-ing prices at Chain A There are three main components in thelabor costs incurred by the chains (a) labor cost of tag changepreparation (b) labor cost of the tag change itself and (c) laborcost of verifying whether the price changes are done correctlywhich include tag change verication in-store resolution of pricemistakes and zone and corporate resolution of price mistakes11

9 The supermarkets often have about 40000 UPC codes in their computerdatabase records but internal studies undertaken by the ESL company indicatethat the supermarkets usually carry no more than 25000 products at any giventime The extra UPC codes are for seasonal or promotional sizes and packages ofproducts and for discontinued products

10 In this paper we only report measures of the marginal cost of changingprices The costs of putting a price tag for the rst time and other costs thatwould be included in the average cost are not included in the gures we reportOnly when discussing Chain E which is the chain subject to item pricing lawsdid we face the issue of cost of pricing (at the rst time) versus the cost of changinga price Since there was no clear way of separating the two types of costs thereported cost gure ($44168 in the second paragraph of Section IV) was excludedaltogether from our calculations Also see footnote 13

11 For a detailed description of the entire price change process with ow-charts documenting the specic steps undertaken in this process and the exacttime period spent on each step see Levy Dutta Bergen and Venable [1997] Anappendix reporting computational details are contained in a working paper ver-sion of this paper which is available upon request

FIGURE IOverview of the Price Change Process

POS denotes Point of Sale and refers to the cash register or the database itis connected to or both For information on the various steps undertaken in eachstage of the price change process and the amount of the labor time spent on mosttime-consuming steps see Table II

Standard price tag changes which include the steps outlined onthe left-hand side of Figure I make up the majority of pricechanges in these chains Some price changes also require addi-tional price signs to be placed at different locations in the storesuch as on an end of aisle display or near the shelf12 These sign

12 These are usually related to the product being on promotion feature ad-vertising display or in-store sale such as ldquomanagerrsquos specialrdquo ldquotodayrsquos specialrdquoetc The steps involved in making sign changes are similar to price changes Themain differences are that (i) the time required for each of the steps in sign changes

THE MAGNITUDE OF MENU COSTS 799

changes add to the menu costs and they are outlined on theright-hand side of Figure I the sign change preparation actualsign changes and sign change verication boxes The bottom twoboxes in Figure I are additional menu costs related to the extrasteps taken in these stores to make sure the tag and sign changeshave been done correctly13

Table II lists each stage of the price change process the totalamount of time spent on each stage each week on average andthe number of tasks performed In addition the table identiessome of the main tasks performed in each stage as well as thefour most time-consuming tasks in each stage To compute thetotal labor time used in changing prices on a weekly basis wecombine the data collected through in-store time and motion ob-servations with information on the volume of products for whichprices are changed These weekly hours are multiplied by thewage rates (adjusted for fringe benets) of the employees used inthe price change process to get the total costs of labor required tochange prices

For the four supermarket chains in our study the total an-nual labor cost of changing the shelf price tags ranges from$40027 to $61414 per store for an average of $52084 (see therst row in Table III making up about 49 percent of the totalmenu costs on average The labor cost of changing the price signsrange from $16411 to $27955 per store for an average of$22183 (see the second row in Table III) making up almost 21percent of the menu costs on average Thus for the four super-market chains the total annual menu costs associated with thelabor required to change prices (shelf price tags and price signscombined) range from $62210 to $81703 per store for an annualaverage of $74267 This is the single largest component of themenu costs we report in this study making up about 701 percentof the total menu costs for these chains on average This shouldnot be surprising given that the most signicant portion of retail

are longer because they are in less standard locations and (ii) there are fewersign changes than standard shelf price tag changes

13 The menu cost measures we report do not include the cost of changingprices in cases where items are moved from shelf to shelf or where shelf space isreallocated by increasing the shelf space for some products at the expense of oth-ers However they do include the cost of pricing new products when they are rstintroduced While this could bias the menu cost measures upward since it reallycaptures the cost of pricing rather than the cost of changing price the size of thisbias is marginal due to the small number of new products For example accordingto ESL company executives the number of new products introduced at thesechains each week ranges from 20 to 100 approximately In comparison to the num-ber of products for which prices are changed each week (3223ndash4316) the biasis negligible

grocery operating expenses is labor costs [Hoch Dreze andPurk 1994]14

III2 Costs of Printing and Delivering New Price Tags

There are direct costs associated with printing and deliv-ering the price and sign tags The order must be recorded andprocessed at the chain sent to the printer recorded and pro-cessed at the printer printed packaged and then delivered toeach store The cost per tag is usually quite low $0017 per tagat Chain A which includes stock costs of $00118 per tag impres-sion and data center operator costs of $00037 per tag and mailroom handling costs of $00010 per tag There are however manyprice changes undertaken each week In total the costs of print-ing and delivering the price and sign tags range from $3048 to$10018 averaging $6014 per store per year (see Table III)These costs comprise less than 6 percent of the total menu costswe report

III3 Costs of Mistakes Made in the Process of Changing Prices

Despite the labor put into checking to make sure that theprice changes are done correctly there are still many price mis-takes that are not caught until customers discover them through-out the week and these mistakes impose costs on the chainClearly the costs associated with these errors must be consideredwhen deciding whether to change prices or not and therefore area relevant dimension of menu costs These mistakes can occur sooften that they were a feature of a Dateline segment on U Ssupermarket chains [NBC April 1992] and an article in MoneyMagazine [April 1993] Both the Money Magazine article andGoodstein [1994] report that on average 10 percent of the prod-ucts they examined had price mistakes A more recent study bythe Federal Trade Commission [1996] reports a total error rate ofabout 5 percent

The menu costs associated with these mistakes include lost

14 Our measure of labor cost may overstate the true costs of changing pricesif supermarkets hoard labor to save hiring and ring costs However this is notlikely to be the case for several reasons First the labor costs of changing priceswe report are based on actual measurements of the minimum amount of time andlabor required to accomplish the task rather than on the number of employeeshired to change prices at the store Second the adjustment in the amount of laboris usually done through hours worked which makes cost of hiring and ring lessrelevant And third the workers on the oor are routinely moved from task totask according to the need These tasks include stocking cleaning price changingcustomer service etc The workers employed by supermarket chains are alwaysbusy and so the opportunity cost of changing price is not zero Therefore laborhoarding is not likely to be an important factor in our measurements

QUARTERLY JOURNAL OF ECONOMICS806

cashier time to correct the errors scan guarantee refunds andinventory mistakes associated with incorrect price tags15 Lostcashier time is measured here in terms of wage payments Scanguarantee refunds are additional price reductions beyond the er-ror or additional items given away for free because of the mis-take Finally the inventory mistakes costs we report include onlythe cost of stockouts which occur when shelf price is lower thanintended

The mistake costs were available at Chains A C and D andthey range from $19135 to $20692 for an average of $20140 perstore annually (see Table III) These costs are the second largestcomponent of menu costs in our study comprising about 19 per-cent of the total

III4 Costs of In-Store Supervision Time Spent on ImplementingPrice Changes

Managers at the store level spend time overseeing imple-menting and troubleshooting the price change process OnlyChains A and B had a measure of the menu costs associated withthis in-store supervision time and both of these came from a self-reported number of hours spent on changing prices by the manag-ers at these chains The hours spent on changing prices were thesame across the chains approximately ve hours per week Thusthe menu costs for in-store supervision time came to $4241 and$6692 per store annually for Chains A and B respectively (seeTable III) These costs comprise less than 6 percent of the totalmenu costs we report in this paper However notice that thesemeasures do not include the cost of the management time spenton price change decisions made at corporate headquarters whichis discussed next

III5 Components of Menu Costs We Are Unable to Measure inDollar Terms

Our data set does not contain the exact dollar measures ofsome menu cost components One such component is the cost ofcorporate management time spent on price change decisions16 In

15 Other likely costs of price mistakes that we do not consider explicitlybecause we are unable to measure them in dollar terms are legal problems (whenthe scanner price is higher than the shelf price) loss in customer goodwill anddecreased protability (when the scanner price is lower than the shelf price)

16 It has been suggested that the cost of managerial decisions is one of themost important components of menu cost See for example Ball and Mankiw[1994] Kashyap [1995] and Meltzer [1995] Since the ESL system was not de-

THE MAGNITUDE OF MENU COSTS 807

the supermarket chains we study prices are generally set at cor-porate headquarters in a weekly meeting where the manager incharge of setting prices looks at a variety of information including(a) any manufacturer wholesale price changes promotions andother related issues (b) past sales for this product and (c) com-petitorsrsquo prices Based on this information and on discussionswith other managers the price-setting manager decides whetherto change prices and if so by how much

To estimate the magnitude of these managerial componentsof the menu costs consider the following In an average chainthere is at least one executive of merchandising who devotesmost of hisher time to pricing decisions In addition there areup to three senior managers who would deal with pricing andto whom category managers report There are also ten-to-twelvecategory managers who are responsible for setting prices on allthe products within their category An additional two-to-fourpeople spend full time handling the implementation of pricechanges across retail outlets coordinating the printing and deliv-ery of price tags and handling pricing problems in the systemAnother ve-to-seven workers gather the data on competitorsrsquoprices and analyse both the competitorsrsquo data and the storersquos ownscanner data to put it in a form useable by managers makingpricing decisions Thus in total there are about 21ndash27 peopleworking at the corporate headquarters on price change decisionsAssuming $150000 as the average annual salary of the executiveof merchandising and senior managers $100000 for categorymanagers and $50000 for the rest the chainwide managerialcost falls in the neighborhood of $23ndash$29 million a year whichseems a substantial amount However note that these pricing de-cision are made for the entire chain and therefore the costs perstore are signicantly less especially for the larger chains Forexample using $29 million as the upper bound the additionalannual menu cost per store for Chains AndashD which on averageoperate about 400 stores each averages about $7250 which ismuch lower than expected and is due to the centralization of theprice change decisions in the chains we study17

signed to save the costs of corporate headquarter managerial time spent on pricechange decisions the ESL company did not measure this component of menucosts The estimates reported in this section are based on the information receivedfrom the ESL company executives

17 A decentralization of the price change process say by allowing the store-level managers to make price change decisions can change these gures tremen-dously For example consider the following thought experiment conducted using

QUARTERLY JOURNAL OF ECONOMICS808

Our menu cost measures also do not include the cost ofchanging prices of direct store delivery (DSD) products Theseproducts are almost completely handled by manufacturers in-cluding stocking monitoring inventories and setting and chang-ing prices18 We have data on the weekly frequency of pricechanges of DSD products in Chain E In an average week thereare 174 price changes of DSD products which is about 10 percentof the supermarketrsquos total weekly price changes Using the costof changing the price of a regular product $133 (see Section IVfor details) the annual cost of changing prices of the DSD prod-ucts in this chain roughly equals $1203419 Our menu cost mea-sures do not include these gures since we do not have similardata for the other chains20

III6 Total Menu Costs

The total annual menu costs reported for each chain perstore are listed in the last row of Table III As the table indicatesthe menu costs range from $91416 to $114188 for an average of$105887 per store per year21 Note that these menu cost mea-

the average annual per store gures for Chains AndashD Suppose that the supermar-ket chains decentralize the price change process by hiring for each store only one-quarter of the price change managing team while at the same time they com-pletely eliminate the corporate level team The resulting annual menu cost perstore would be $830887 ( 5 $105887 1 $725000) which would dwarf any of themeasurable menu cost gures we report in this study Even if the average storeonly hired just the merchandising manager at the annual cost of $150000 itwould still incur annual managerial cost of about $255887 ( 5 $105887 1$150000) In other words such a trivial decentralization would double the store-level menu costs This would indeed make the cost of price change decisions themost important component of menu cost

18 DSD products usually are high-volume fast-moving or perishable prod-ucts such as milk soda eggs bread dairy snacks etc In the chains we studyabout 10ndash20 percent of the products are of a DSD type but that share may reachas much as 40 percent of the products carried [Direct Store Delivery Work Groupet al 1995]

19 The process of changing prices of DSD and of regular products is similarBut with DSD products there are additional costs of the time spent on driving tothe store parking and setting up the price change process at each store

20 Our measures of menu cost also do not incorporate the cost of informingconsumers about price changes which can take a variety of forms such as newspa-per ads and inserts TV and radio ads in-store promotion signs etc Finally wehave no data on lost customer goodwill and damaged reputation caused by dis-crepancies between price tag and cash register [Okun 1981 Carlton and Perloff1994 Haddock and McChesney 1994]

21 The variation in the menu costs across the chains is mostly due to wagerate and labor-efciency variations Also note that since the supermarket chainsin our sample are similar in the size of their stores carry similar sets of productsand follow similar processes of price change and price change decisions it is rea-sonable to believe that the chains incur similar types of costs Therefore as notedunderneath Table III these menu cost measures are computed by replacing theunreported gures by the averages of the available values from the other chains

THE MAGNITUDE OF MENU COSTS 809

sures include only the components we could accurately measurein dollar terms which are discussed in subsections III1ndashIII4

IV ITEM PRICING LAWS AND MENU COSTS

In this section we provide evidence on the menu costs for anadditional chain (Chain E) which unlike the other four chainsoperates in a state with an item pricing law The most importantaspect of item pricing laws is that they require a price tag on eachindividual item sold not just on the shelf which is what the otherfour chains in our sample do For example the item pricing lawin Connecticut requires that the grocers ldquoshall mark or cause tobe marked each consumer commodity which bears a UniversalProduct Code with its retail pricerdquo 22 From a menu cost perspec-tive the requirement of posting prices on every item (in additionto the shelf price tag) introduces additional costs in the processof changing prices

Although most of the steps involved in changing prices arethe same for both types of chains stores that are subject to itempricing laws have to undertake additional steps to obey this law23

The labor cost component of menu costs in Chain E totals $75127a year of which $49710 is the cost of the labor time spent onchanging the prices of individual items $3234 is the cost of thelabor time spent on shelf tag replacements and $22183 is thecost of the labor time spent on sign changes (see Table III)24 Anadditional $44168 is spent annually putting prices on new itemsas they are brought to the shelves Although we do not includethis last gure in our menu cost measures because we do not haveinformation on how much of it is due to price change activity andhow much due to just pricingmdashthese costs are clearly a directconsequence of the item pricing law The printing and deliverycost of price tags and price signs are $7644 and the mistake

22 Public Act No 75ndash391 An Act Concerning Pricing of Consumer Merchan-dise [Public Acts of the State of Connecticut 1975 Vol 1 p 390]

23 These steps which are in addition to the regular steps undertaken toreplace price tags on the shelves include (1) obtaining item price tags (2) settingup workstations (3) locating the product (4) removing an item from the shelf (5)removing old price tag (6) setting marking gun (7) applying new price tag and(8) returning the item back to the shelf

24 Since we do not have a measure of the cost of labor time spent on signchanges and the cost of in-store managerial supervision time for this chain weuse the average of the chains that report them (A and D) Note also that thehourly wage rate of $907 paid by Chain E is lower than the hourly wage of about$1400ndash$2000 paid by Chains AndashD

QUARTERLY JOURNAL OF ECONOMICS810

25 Further note that the chains with smaller menu costs are likely tochange their prices more frequently which suggests that the gures of the totalannual menu costs understate the differences between Chain E and the otherchains Indeed despite the large difference in the menu cost per price change thetotal annual menu costs per store for Chain E ($109036) are more comparable tothose of Chains AndashD ($105887)

26 In calculations that follow we use industry averages because (1) thechains did not share this proprietary information with us and (2) we were re-quired to keep the identity of these chains condential as some of these numbersare detailed enough to enable some readers to identify the chains under study

costs are $20799 These gures along with the amount of $5466for the cost of in-store managerial supervision time yield totalannual menu costs of $109036 per store

Although the magnitude of the total annual menu costs seemsimilar to the other four chains note that the average weeklyfrequency of price changes in Chain E is only 1578 which is only403 ( 5 15783916) percent of the price changes made by theother four chains Thus the average menu cost per price changefor Chain E is $133 (see Table IV last row) In contrast the corre-sponding gures for Chains AndashD average $052 Hence the menucosts per price change incurred by the supermarket chain facingitem pricing laws are more than two and a half times the amountincurred by chains that are not subject to this law25 Overallthese ndings suggest that legal restrictions of the type of itempricing laws can have a signicant impact on the menu costs in-curred by sellers

V SIGNIFICANCE OF THE MENU COSTS

The next natural question to ask is how important are thesecosts To address this question we (1) provide several relativemeasures of the menu costs (2) discuss the effect of the menucosts on supermarketsrsquo price change activity and (3) discuss mac-roeconomic implications by relating our ndings to the existingtheoretical models of menu costs In each case we provide addi-tional evidence to help assess the importance of these menu costs

V1 Relative Measures of the Menu Costs

In order to assess the relative magnitude of the menu costsreported in Section IV we now present the menu cost gures rela-tive to the average store-level revenues and net prot margins26

In addition we present the menu cost gures per price changeThe annual average revenues of a large U S supermarket

chain of the type and size included in our sample is $15052716

per store27 According to the second row of Table IV the ratio ofmenu costs to revenues for Chains AndashD ranges between 061ndash076percent averaging 070 percent28 We relate the size of thesegures to the existing theoretical menu cost models in sub-section V3

Net prot margin which measures the revenues minus allcosts is approximately 1ndash3 percent of revenues for these chains[Montgomery 1994] so we use 2 percent as a working averageThe reason for the low prot rate in this industry is the intensecompetition [Calatone et al 1989] especially at the regional level[Chevalier 1995] which has been increasing since the early 1990s[Progressive Grocer November 1992 p 50] It follows that theaverage store protability for these chains equals $301054 peryear Therefore the ratio of total menu cost to net margin forChains AndashD ranges between 304ndash379 percent for an average of352 percent Thus the menu costs we report in this study repre-sent a signicant share of supermarketsrsquo prots

Another way to look at the menu cost gures we report is toexpress them relative to the frequency of price changes In thelast row of Table IV we present the menu cost gures per pricechange for each chain As the table indicates the cost of changinga price in Chains AndashD ranges between $046ndash$068 for an averageof $052 For Chain E the gure is substantially larger $133 perprice change29 These gures are lower than the estimated cost of

27 This is the average of two different estimates $12945432 and$17160000 The source of the rst gure is internal record of a supermarketchain of the type and size studied here The second gure comes from Supermar-ket Business [1993 p 52]

28 We also measured the menu costs in terms of controllable operating ex-penses (which are the portion of costs that the retailer has direct control over andtherefore are often the costs that the retailer is most focused on managing) andgross margins (which measure the supermarket revenues minus direct cost of theproducts it sells) We nd that the menu costs comprise 313 percent of controlla-ble operating expenses and 281 percent of gross margins at these chains on aver-age Finally if we measure the menu costs relative to the number of productscarried per store (about 25000) then we nd that the menu costs per productaverage $423 for Chains AndashD See Table IV and its footnotes for details

29 We can also try to express the menu cost gures relative to the numberof individual items sold by these chains each year (Note the difference betweennumber of products carried and number of items sold As an example a TartarControl Crest 8oz would be considered a product carried and 300 units of themsold per year would be considered number of items sold) Using $170 as the aver-age price of all the products sold we nd that the menu cost per item sold for thefour chains is in the range of $00103ndash$00129 for an average of $00119 (see TableIV second to last row) To see the relative magnitude of these gures note thataccording to Berkowitz Kerin and Rudelius [1986 p 319] the goal of the super-market chains of the type we study ldquo is to make 1 penny of prot on each dollarof salesrdquo Thus menu cost per item sold when adjusted for the average price

THE MAGNITUDE OF MENU COSTS 813

$200ndash$300 per price change reported by Slade [1996a] Thereare several possible reasons for this (1) our menu cost gures arebased on actual measurements of the resources that go into theprice change process whereas she estimates menu costs econo-metrically as model coefcients using a mix of store-level priceand aggregate cost data (2) we cover 25000 products that thesupermarkets carry rather than a single product category (3) ourmenu cost gures do not include all components of menu costsand (4) there could be differences in wage rates that may be im-portant given the signicance of the labor cost component inmenu costs

V2 The Effect of Menu Costs on the Price Change Activity of theSupermarkets

In this section we present evidence which suggests that thesemenu costs may be forming a barrier to price change activity Tobegin with consider the effect of the item pricing law on the pricechange activity of Chain E The data on the weekly frequency ofprice changes in each chain are displayed in the last two rows ofTable I According to these gures the average weekly frequencyof price changes in Chain E is only 1578 Thus on average ChainE changes the prices of only 631 percent of its products eachweek In contrast the average weekly frequency of price changesat Chains AndashD ranges from 3223 to 4316 for the four-chain aver-age of 3916 price changes weekly So Chains AndashD change priceson 1289 to 1726 percent of their products each week yielding afour-chain average of 1566 percent Thus Chain E which facesthe item pricing law changes prices only about one-third timesas frequently as do Chains AndashD30

Moreover within Chain E there are 400 products that areexempt from the item pricing law and thereby face lower menucosts We nd that there are an average of 83 weekly pricechanges for these products yielding 21 percent of these productschanging prices So within Chain E they change prices over threetimes as frequently for products with lower menu costs than for

roughly equals one-half of their target net prot per item which seemssubstantial

30 However note that our comparison of the two types of chains may not becompletely ceteris paribus because these stores are located in different states andtherefore there may be other chain-specic factors (in addition to item pricinglaws) that distinguish these stores We do not have any specic information onthese differences We do know however that the stores in these chains are similarin size and carry similar sets of products

the products with higher menu costs Note that this nding is onthe price change activity within the same chain offering almost anatural experiment on the impact of menu costs on the chainrsquospricing behavior Hence we provide evidence both across chainsas well as across products within a chain that as the costs ofchanging price go up the frequency of price changes goes downThus the menu costs we nd are signicant enough to affect thechainrsquos price change practice

We also have additional evidence from Chains A B and Dabout these menu costs being a barrier to certain price changesand it is summarized in Table V According to the Price Manage-ment Department of Chain A the chain experiences cost in-creases on 860 products in an average week to which it wouldlike to react with a price increase31 However on average 22 per-cent of these price increases are not implemented immediatelybecause the cost of changing prices for these products is too highto make it economically worthwhile Figures of the same magni-tude were reported by other chains For example Chain D experi-ences cost increases for 961 products in an average week Out ofthese the chain adjusts prices of only 633 products The re-maining 34 percent of the prices are left unadjusted because ofthe menu costs Similarly Chain B nds it economically ineffi-cient to adjust prices of 508 ie 30 percent of its products eachweek because of menu costs This provides additional evidencethat the menu costs incurred by these chains are preventing priceadjustments to some costs changes leading to price rigidities ofthe products involved32 Note that although we do not have simi-lar data for Chain E we would expect signicantly lower num-bers on this measure at that chain These gures also suggest anupper bound on the benet of complete price exibility under thecurrent pricing practice of weekly price adjustments Howeverif new technologies (eg ESL systems) and new pricing prac-tices (eg a decentralization of the price change decisions) are

31 Our data contain information only on the frequency of cost increasesAlthough it is more than likely that the supermarkets are experiencing cost de-creases as well our data set contained no information on such decreases

32 Menu costs may even be playing a role in the observed movement towardpricing strategies that rely on fewer price changes such as EDLP [Blattberg andNeslin 1989 Lattin and Ortmeyer 1991 Marketing News April 13 1992 p 8]According to Progressive Grocer [November 1992 p 50] ldquoA growing number ofoperators say they have switched from high-low pricing [to EDLP] They cite theinefciencies of making frequent price changes rdquo Similarly Hoch Dreze andPurk [1994 p 16] state that EDLP lowers operating costs by lowering ldquo in-store labor costs because of less frequent changeovers in special displaysrdquo

adopted allowing a fundamental change in the way the pricingmechanism is currently set the managers could consider morefrequent price change activity (eg multiple times each week) asmenu costs go down

In this paper we measure the menu costs at the chainsrsquo cur-rent level of price change activity It may be worthwhile to specu-late on the shape of the cost function relating menu costs to thefrequency of price changes by assessing how these costs wouldchange if the price change activity were to increase or to decreaseIt seems likely that many of the costs we report in this paper will(approximately) change linearly with additional price changeswithin the current range of price changes the chains are under-taking (plus or minus perhaps a thousand per week) For ex-ample the labor costs associated with changing a shelf price tagcosts of verifying price changes and the costs of mistakes oc-curring during this process all increase linearly with the fre-quency of price changes This is because most of the time-consuming steps involved in the price change process must berepeated each time an additional shelf price tag is changed (seeTable II) Further we were unable to nd many tasks that gener-ated signicant returns to scale It is unclear what cost savingsare available if the price change activity drops substantially be-

QUARTERLY JOURNAL OF ECONOMICS816

low the levels it is at now Clearly if price changes were nearzero or done less frequently than weekly (say monthly) therecould be major differences in these costs

What is less clear is how these costs would change at moreextreme levels of price change activity With less frequent pricechanges the menu costs could probably be reduced signicantlyalthough the cost of deciding what prices to set initially and thecost of putting the initial shelf price tags would still remain as alower bound of the menu cost However for achieving more priceexibility by changing prices more frequently (ie multiple timeseach week) substantial changes must be undertaken At presentthe supermarket chains are set up to make the majority of theirprice changes on a weekly basis with the appropriate systems inplace to make this process most efcient For example in orderto save costs and to have higher quality price tags (eg withcolor more details greater clarity glossy etc) the chains oftensend new price tag requests to a printing shop which takes threedays to print and deliver the labels to each store Then giventhe large number of price changes taking place and the goals ofminimizing customer disruptions and labor costs (such as over-time pay) and coordinating with advertised price promotions theprices are changed in the store over a two-to-three-day period (seeTable VI) The combination of these schedule and built-in lags isacceptable under the current practice of changing prices weeklybut would have to be adjusted dramatically to allow for signifi-cantly more frequent price changes on a regular basis

Perhaps even more imposing are the costs of changing themanagerial costs associated with the current weekly system ofprice changes The process of pricing at this organizational levelis not a self-contained activity taking place in isolation from otheroperations of the supermarket management Rather it is a partof a larger system of business decisions and operations The cur-rent process of operations (such as data collection and theiranalysis management meetings coordination of the decisionsacross functional areas etc) is set up to function on a weeklybasis33 Further these management accounting and logisticssystems are currently built around a tremendous amount of in-

35 If the supermarket chains indeed restructure the entire price change pro-cess and begin to change prices much more frequently (say two-to-three times aweek) on a regular basis then the shape of this cost function could change in anunpredictable way

V3 Relating Our Findings to the Existing Theoretical Models ofMenu Costs

In order to assess the magnitude of these menu cost guresin the context of the existing theoretical menu cost literatureconsider the following calculation experiments done within theframework of two theoretical menu cost models Blanchard andKiyotaki [1987] study a general equilibrium menu cost modelwith monopolistic competition and with unit elasticity of aggre-gate demand with respect to real money balances According totheir calculations menu costs of the magnitude of 008 percent ofrevenues which they consider ldquovery smallrdquo may be sufcient toprevent adjustment of prices Ball and Romer [1990] conductsimilar calculations in the framework of a model with imperfectcompetition and menu costs They nd that for plausible markupand labor elasticity parameter values menu costs needed to pre-vent price adjustment are 070 percent of revenues which as theysuggest are nonnegligible For smaller menu costs eg 004 per-cent of the revenue which Ball and Romer consider ldquotrivialrdquo im-plausibly large values of markup and labor elasticity parametersare needed to prevent price adjustment to monetary shocks

According to the gures in Table IV the reported menu costto revenues ratio for Chains AndashD averages 070 percent rangingfrom 061 percent to 076 percent These are signicantly largerthan the ldquotrivialrdquo 004 or 008 percent gures mentioned abovesuggesting that the menu cost gures we nd here are nontrivialFurther under the model and parameter values considered byBlanchard and Kiyotaki [1987] the menu cost gures we nd arehigher than the theoretical minimum needed to form a barrier toprice adjustments Under the model and parameter values con-sidered by Ball and Romer [1990] the reported menu costreve-nue ratio for all but one chain reaches or crosses the theoreticalthreshold of 070 needed to form a barrier to price adjustmentsThe existence of numerous unmeasured menu cost componentsdiscussed in subsection III5 also raises the possibility that theactual menu costs incurred by these chains are signicantlyhigher than that threshold This suggests that the menu costs wereport may be large enough to form a barrier to nominal priceadjustments when interpreted in the context of these models

An issue of interest in this literature is time-dependent ver-sus state-dependent pricing rules (see for example Caplin andLeahy [1991]) The evidence from our data set on the timing of

THE MAGNITUDE OF MENU COSTS 819

price changes suggests that the price change decisions in thesesupermarkets have a strong time-dependent price-setting ele-ment36 For example according to Table VI the prices in Chain Aare changed weekly according to the following schedule the pricechanges of general merchandise that is advertised is done Satur-day nights grocery and produce prices are changed Sundaynights the rest of the general merchandise prices are changed onMonday nights and the prices of advertised grocery items arechanged on Tuesday nights Thus as the gures in Table VI indi-cate over 96 percent of the price changes are done during Sundayand Monday nights However this does not imply that state-dependent pricing rules are unimportant Even if price changesacross product categories follow a prescheduled weekly time ta-ble the prices of which products to change is likely to be a state-dependent decision For example it could depend on changes insupply and demand conditions such as competitorsrsquo price changedecisions Indeed Levy Dutta and Bergen [1996] use retailstore-level orange juice price and cost data to demonstrate thatthe extent of price response to cost shocks that is the extent ofprice rigidity may depend on the nature of supply shocks37

We do not want to overstate the usefulness of our data fordirectly addressing the issue of monetary nonneutrality On onehand authors such as Caplin and Spulber [1987] have demon-strated that under certain conditions individual price rigiditymay not be sufcient for aggregate price rigidity but unfortu-nately our data do not speak directly to this issue38 On the otherhand authors such as Akerlof and Yellen [1985] Mankiw [1985]Parkin [1986] and Caplin and Leahy [1997] have shown that even

36 Danziger [1983] Caballero [1989] and Ball and Mankiw [1994] suggestthat time-dependent price adjustment of the type documented here can be optimalif the cost of gathering information about the state exceeds the cost of making theprice adjustment itself

37 We also considered the possibility of convexities in the cost of changingprices Our data do not suggest many convexities since the labor time spent inthe price tag change process the cost of printing and delivering price tags andin-store supervision time do not change with the size of a price change The onlymeasurable component of menu costs that could be convex is the cost of mistakesmade the larger the price change the higher the probability of a customer notic-ing the mistake and the larger the amount required to be refunded as compensa-tion Among the unmeasured components of menu cost the cost of corporatemanagerial time may increase with the size of a price change because larger pricechanges may require more serious consideration

38 Also see Balke and Wynne [1996] and Bryan and Cecchetti [1996] Sincewe do not have measures of how menu costs change over time our data also havelittle to say about time variation in menu costs or about the relationship betweenmenu costs and ination which during the period of the data collection (1991ndash1992) averaged about 3 percent annually

QUARTERLY JOURNAL OF ECONOMICS820

small menu costs can be relevant since they may be sufcient togenerate substantial aggregate nominal rigidity and thus largebusiness cycles Therefore as Blinder [1994] Kashyap [1995]and Slade [1996a] emphasize it is important to search for directevidence that such costs are indeed present at the micro level Bydirectly identifying documenting and measuring the magnitudeof menu costs at the store level we are taking an important stepin that direction

VI CONCLUSION AND FUTURE RESEARCH

Our main contribution is that we provide direct microeco-nomic evidence on the actual magnitude of menu costs for fourlarge U S retail supermarket chains The annual menu costs perstore at these chains average $105887 comprising 070 percentof revenues 352 percent of net prot margins and $052 perprice change on average

Further we provide evidence which suggests that thesemenu costs may be forming a barrier to price changes Specifi-cally we show that (1) supermarket chains not subject to itempricing law change prices two and a half times more frequentlythan the chain that is subject to the law (2) within the chain thatis subject to the item pricing law they change prices over threetimes as frequently for products that are exempt from this lawthan for the products which are subject to this law and (3) wend that these chains do not adjust prices of up to one-third ofthe products for which they face cost increases because of menucost considerations

When we relate these ndings to the existing theoreticalmodels of menu costs we conclude that the magnitude of menucosts we nd is large enough to be capable of having macroeco-nomic signicance Specically when considered in the context ofthe theoretical menu cost models of Blanchard and Kiyotaki[1987] and Ball and Romer [1990] we nd that the menu costgures we report are ldquonontrivialrdquo and their relative magnitudescross the minimum theoretical threshold needed to form a barrierto price adjustments

Despite the high relative magnitude of the marginal cost ofchanging price that we found the data still indicate frequentweekly price changes This is because of the high marginal bene-t of changing price which is due to the erce competition foundin the retail supermarket industry That marginal benets may

THE MAGNITUDE OF MENU COSTS 821

outweigh the marginal costs of changing prices in this industryhowever does not rule out the possibility that menu costs of themagnitude we nd here can create substantial nominal rigidityin other industries or markets In less competitive industries andmarkets menu costs of the type and magnitude we documenthere are likely to have a bigger impact on the frequency of priceadjustment and consequently on the degree of price rigidity

At a minimum the direct dollar measures of menu costs wereport here can be used as a starting point for future research onmeasuring their magnitude in other industries and establish-ments We anticipate that these menu costs will be similar inother markets which rely on posted prices (such as drugstoresdepartment stores etc) because the steps involved in the pricechange process are likely to be similar What may differ are thefrequency of price changes and the labor wage rates at thesestores For example since supermarket chains change thousandsof prices each week the total annual menu costs incurred bythese chains per store are likely to be high in comparison to otherretail formats such as chain drugstores or department storesThere are however a variety of industries for which the stepsinvolved in changing prices would be signicantly different fromthose reported in our study For example business-to-businesssales which often rely on a sales force will require changes in thelist price sheets changes in the instructions to the sales forcewhich may include education and discussion with the salespeoplein the company and so forth These business-to-business pricesalso often have more complex pricing schemes including quantitydiscounts bundling and individually negotiated prices As an-other example the composition of the cost of changing the news-stand prices of magazines [Cecchetti 1986] or the prices ofproducts sold through catalogs [Kashyap 1995] are different frommany of the menu cost components we discuss here Further thending that a centralization of pricing decisions makes the store-level managerial component of menu cost relatively small sug-gests that the managerial menu costs likely are highest insettings where price change decisions are decentralized Thus fu-ture empirical work should look at menu cost and its compositionin a variety of other industries markets and products with bothcentralized as well as decentralized price change decisions in or-der to see whether the magnitude of these costs can be general-ized and benchmarks can be established Further there aretechnological changes taking place in this and other industries

that promise to alter the structure of menu costs which deserveattention At the theoretical level our ndings suggest that it maybe worthwhile to explore models which incorporate the idea ofitem pricing laws as an additional component of menu costs

ate some barriers to price change activity at these retail super-market outlets they are not large enough to prevent a signicantshare of prices to adjust

The paper is organized as follows In Section II we describethe data In Section III we discuss the price change process insupermarket chains and report absolute measures of menu costsIn Section IV we assess the effect of item pricing laws on menucosts In Section V we discuss the signicance of the menu costsWe end with conclusions and suggestions for future research

II DATA DESCRIPTION

The data come from a company that sells electronic shelf la-bel (ESL) systems These systems allow retailers to change theshelf prices electronically from a central computer (where pricechanges are actually done) via a wireless communication systemand thus reduce the physical costs and lead times currently asso-ciated with changing shelf prices In order to sell the product thecompany needed to validate what the existing costs of changingshelf prices were in supermarket chains ie the existing levelsof menu costs This company received access from corporate head-quarters at each of the ve chains in our sample to go to represen-tative stores and carefully record the exact steps involved in theprice change process These studies considered the entire pricechange process in each chain For this detailed work-ow sche-matics of each task in the price change process was developedObservations of the process were conducted in multiple stores ofthe chains (at least two representative stores for each chain) toverify its accuracy Information received from chainsrsquo pricing sys-tems in-store observations in-store counts and in-store timemeasurements (with a stopwatch) were used to determine thevolume of work performed in each step of the tasks weekly fre-quency of each step performed and the exact amount of time re-quired to perform one unit of the work After computing the totalhours per task this information was reconciled with the knowntotal hours spent each week This allowed for task level compari-sons for the existing and test process Each study required hun-dreds of man-hours to create The studies were conducted duringthe years 1991ndash1992

Although we believe the menu costs reported in this paperare representative of menu costs in the U S supermarket indus-try we should mention that they may be biased upward because

THE MAGNITUDE OF MENU COSTS 795

the rm had an incentive to overestimate the magnitude of themenu costs in order to sell the ESL system We think howeverthat the menu cost measures we report in this paper are not sub-ject to signicant biases of this sort for a number of reasonsFirst the ESL people measured and documented all price changeactivities jointly with the supermarket employees using the wagegures provided by the supermarket management Second timeand motion measurements of the type used for measuring themenu costs we report here are routinely done by supermarketchains themselves in order to assess the efciency of their pricechange processes The supermarket managers compared theirgures to the ESL company gures and found them to be similarFurther these gures were presented to upper management ofthese chains and were found to be representative of their coststructures In fact the validity of the menu cost measures con-structed by the ESL company was never disputed If there wasany disagreement between the ESL company and the supermar-ket chains it was about the size of the savings the ESL systemwould provide not about the accuracy of the menu cost measure-ments7 Further we looked at these reports and searched for g-ures that could be biased upward There were a few such as lossof goodwill costs and inventory holding costs and to be on theconservative side we did not include them in our measures ofmenu costs Thus we only report gures for which we could seeno upward bias Finally note that the menu cost gures we reportare clearly biased downward because we were unable to measurein dollar terms several components of menu costs and thus theyare not included in our gures (see subsection III5 for details)

Table I displays some general information about the super-market chains we study their pricing strategy and informationabout the frequency of weekly price changes the stores under-take The chains involved in this study are all large U S super-market chains from different regions in the United Statesranging from the Northeast to the West Coast and operating anaverage of 400 stores each At the request of these retailers wewill keep the companies in this study anonymous but they areall large multistore chains that seem reasonably representativeof large supermarket chains currently selling in the United

a HL (HighLow) and EDLP (Every Day Low Price) refer to the general pricing strategy followed by theretail chain Under the EDLP strategy the retailer rsquos prices are low for extended periods of time and there-fore it will offer fewer promotional sales or discounts Under the HL pricing strategy in contrast the retail-errsquos prices are higher and the retailer tends to offer more frequent discounts through sales and promotionsSee the text for more details

b The share of products for which prices change on an average week is the ratio of number of pricechanges per store per week to 25000 The latter is the average number of products carried per store eachweek

States These chains are similar in the variety selection andquantity of the products they carry Supermarket chains of thistype make up $310146666000 in total annual sales which is863 percent of total supermarket chain sales in 1992 [Supermar-ket Business 1993] so the chains in our sample are representativeof a major class of the retail grocery trade

According to the second row in Table I the number of weeklyprice changes in Chains AndashD ranges from 3223 to 4316 for anaverage of 3916 per store8 The variation in the number of weeklyprice changes across the chains is due in large part to their choiceof pricing strategy Chains A and B follow a highlow (HL) pricestrategy while Chains C and D follow an everyday-low-pricestrategy (EDLP) Under the EDLP strategy the retailerrsquos pricesare low for an extended period of time and therefore it will offerfewer promotional sales or discounts Under the HL pricing strat-egy in contrast the retailerrsquos prices are higher and the retailertends to offer more frequent discounts through sales and promo-tions The pricing strategy therefore will have an effect on thefrequency of price changes observed In particular we would ex-

8 Since Chain E is subject to an item pricing law it is discussed separatelyin Section IV

THE MAGNITUDE OF MENU COSTS 797

pect EDLP stores to have less frequent price changes in compari-son to the HL stores Indeed according to Table I Chains A andB tend to have a higher number of weekly price changes (4278and 4316 respectively) than Chains C and D (3846 and 3223respectively)

Supermarkets of the size we study tend to carry around25000 different items on a regular basis9 The last row in thetable presents the share of the 25000 products for which the su-permarket chains change their prices in a period of one weekThe average share for the four chains is 1566 percent

III ABSOLUTE MEASURES OF MENU COSTS

There are four components of menu costs that we are able tomeasure in dollar terms10 These are (1) the cost of labor requiredto change the shelf price tags (2) the cost of printing and deliv-ering new price tags (3) the cost of mistakes made during theprocess of changing prices and (4) the cost of in-store supervisiontime spent on implementing price changes

III1 Costs of the Labor Required to Change Shelf Prices

Figure I displays an overview of the steps involved in chang-ing prices at Chain A There are three main components in thelabor costs incurred by the chains (a) labor cost of tag changepreparation (b) labor cost of the tag change itself and (c) laborcost of verifying whether the price changes are done correctlywhich include tag change verication in-store resolution of pricemistakes and zone and corporate resolution of price mistakes11

9 The supermarkets often have about 40000 UPC codes in their computerdatabase records but internal studies undertaken by the ESL company indicatethat the supermarkets usually carry no more than 25000 products at any giventime The extra UPC codes are for seasonal or promotional sizes and packages ofproducts and for discontinued products

10 In this paper we only report measures of the marginal cost of changingprices The costs of putting a price tag for the rst time and other costs thatwould be included in the average cost are not included in the gures we reportOnly when discussing Chain E which is the chain subject to item pricing lawsdid we face the issue of cost of pricing (at the rst time) versus the cost of changinga price Since there was no clear way of separating the two types of costs thereported cost gure ($44168 in the second paragraph of Section IV) was excludedaltogether from our calculations Also see footnote 13

11 For a detailed description of the entire price change process with ow-charts documenting the specic steps undertaken in this process and the exacttime period spent on each step see Levy Dutta Bergen and Venable [1997] Anappendix reporting computational details are contained in a working paper ver-sion of this paper which is available upon request

FIGURE IOverview of the Price Change Process

POS denotes Point of Sale and refers to the cash register or the database itis connected to or both For information on the various steps undertaken in eachstage of the price change process and the amount of the labor time spent on mosttime-consuming steps see Table II

Standard price tag changes which include the steps outlined onthe left-hand side of Figure I make up the majority of pricechanges in these chains Some price changes also require addi-tional price signs to be placed at different locations in the storesuch as on an end of aisle display or near the shelf12 These sign

12 These are usually related to the product being on promotion feature ad-vertising display or in-store sale such as ldquomanagerrsquos specialrdquo ldquotodayrsquos specialrdquoetc The steps involved in making sign changes are similar to price changes Themain differences are that (i) the time required for each of the steps in sign changes

THE MAGNITUDE OF MENU COSTS 799

changes add to the menu costs and they are outlined on theright-hand side of Figure I the sign change preparation actualsign changes and sign change verication boxes The bottom twoboxes in Figure I are additional menu costs related to the extrasteps taken in these stores to make sure the tag and sign changeshave been done correctly13

Table II lists each stage of the price change process the totalamount of time spent on each stage each week on average andthe number of tasks performed In addition the table identiessome of the main tasks performed in each stage as well as thefour most time-consuming tasks in each stage To compute thetotal labor time used in changing prices on a weekly basis wecombine the data collected through in-store time and motion ob-servations with information on the volume of products for whichprices are changed These weekly hours are multiplied by thewage rates (adjusted for fringe benets) of the employees used inthe price change process to get the total costs of labor required tochange prices

For the four supermarket chains in our study the total an-nual labor cost of changing the shelf price tags ranges from$40027 to $61414 per store for an average of $52084 (see therst row in Table III making up about 49 percent of the totalmenu costs on average The labor cost of changing the price signsrange from $16411 to $27955 per store for an average of$22183 (see the second row in Table III) making up almost 21percent of the menu costs on average Thus for the four super-market chains the total annual menu costs associated with thelabor required to change prices (shelf price tags and price signscombined) range from $62210 to $81703 per store for an annualaverage of $74267 This is the single largest component of themenu costs we report in this study making up about 701 percentof the total menu costs for these chains on average This shouldnot be surprising given that the most signicant portion of retail

are longer because they are in less standard locations and (ii) there are fewersign changes than standard shelf price tag changes

13 The menu cost measures we report do not include the cost of changingprices in cases where items are moved from shelf to shelf or where shelf space isreallocated by increasing the shelf space for some products at the expense of oth-ers However they do include the cost of pricing new products when they are rstintroduced While this could bias the menu cost measures upward since it reallycaptures the cost of pricing rather than the cost of changing price the size of thisbias is marginal due to the small number of new products For example accordingto ESL company executives the number of new products introduced at thesechains each week ranges from 20 to 100 approximately In comparison to the num-ber of products for which prices are changed each week (3223ndash4316) the biasis negligible

III2 Costs of Printing and Delivering New Price Tags

There are direct costs associated with printing and deliv-ering the price and sign tags The order must be recorded andprocessed at the chain sent to the printer recorded and pro-cessed at the printer printed packaged and then delivered toeach store The cost per tag is usually quite low $0017 per tagat Chain A which includes stock costs of $00118 per tag impres-sion and data center operator costs of $00037 per tag and mailroom handling costs of $00010 per tag There are however manyprice changes undertaken each week In total the costs of print-ing and delivering the price and sign tags range from $3048 to$10018 averaging $6014 per store per year (see Table III)These costs comprise less than 6 percent of the total menu costswe report

Despite the labor put into checking to make sure that theprice changes are done correctly there are still many price mis-takes that are not caught until customers discover them through-out the week and these mistakes impose costs on the chainClearly the costs associated with these errors must be consideredwhen deciding whether to change prices or not and therefore area relevant dimension of menu costs These mistakes can occur sooften that they were a feature of a Dateline segment on U Ssupermarket chains [NBC April 1992] and an article in MoneyMagazine [April 1993] Both the Money Magazine article andGoodstein [1994] report that on average 10 percent of the prod-ucts they examined had price mistakes A more recent study bythe Federal Trade Commission [1996] reports a total error rate ofabout 5 percent

The menu costs associated with these mistakes include lost

14 Our measure of labor cost may overstate the true costs of changing pricesif supermarkets hoard labor to save hiring and ring costs However this is notlikely to be the case for several reasons First the labor costs of changing priceswe report are based on actual measurements of the minimum amount of time andlabor required to accomplish the task rather than on the number of employeeshired to change prices at the store Second the adjustment in the amount of laboris usually done through hours worked which makes cost of hiring and ring lessrelevant And third the workers on the oor are routinely moved from task totask according to the need These tasks include stocking cleaning price changingcustomer service etc The workers employed by supermarket chains are alwaysbusy and so the opportunity cost of changing price is not zero Therefore laborhoarding is not likely to be an important factor in our measurements

cashier time to correct the errors scan guarantee refunds andinventory mistakes associated with incorrect price tags15 Lostcashier time is measured here in terms of wage payments Scanguarantee refunds are additional price reductions beyond the er-ror or additional items given away for free because of the mis-take Finally the inventory mistakes costs we report include onlythe cost of stockouts which occur when shelf price is lower thanintended

The mistake costs were available at Chains A C and D andthey range from $19135 to $20692 for an average of $20140 perstore annually (see Table III) These costs are the second largestcomponent of menu costs in our study comprising about 19 per-cent of the total

III4 Costs of In-Store Supervision Time Spent on ImplementingPrice Changes

Managers at the store level spend time overseeing imple-menting and troubleshooting the price change process OnlyChains A and B had a measure of the menu costs associated withthis in-store supervision time and both of these came from a self-reported number of hours spent on changing prices by the manag-ers at these chains The hours spent on changing prices were thesame across the chains approximately ve hours per week Thusthe menu costs for in-store supervision time came to $4241 and$6692 per store annually for Chains A and B respectively (seeTable III) These costs comprise less than 6 percent of the totalmenu costs we report in this paper However notice that thesemeasures do not include the cost of the management time spenton price change decisions made at corporate headquarters whichis discussed next

III5 Components of Menu Costs We Are Unable to Measure inDollar Terms

Our data set does not contain the exact dollar measures ofsome menu cost components One such component is the cost ofcorporate management time spent on price change decisions16 In

15 Other likely costs of price mistakes that we do not consider explicitlybecause we are unable to measure them in dollar terms are legal problems (whenthe scanner price is higher than the shelf price) loss in customer goodwill anddecreased protability (when the scanner price is lower than the shelf price)

16 It has been suggested that the cost of managerial decisions is one of themost important components of menu cost See for example Ball and Mankiw[1994] Kashyap [1995] and Meltzer [1995] Since the ESL system was not de-

THE MAGNITUDE OF MENU COSTS 807

the supermarket chains we study prices are generally set at cor-porate headquarters in a weekly meeting where the manager incharge of setting prices looks at a variety of information including(a) any manufacturer wholesale price changes promotions andother related issues (b) past sales for this product and (c) com-petitorsrsquo prices Based on this information and on discussionswith other managers the price-setting manager decides whetherto change prices and if so by how much

To estimate the magnitude of these managerial componentsof the menu costs consider the following In an average chainthere is at least one executive of merchandising who devotesmost of hisher time to pricing decisions In addition there areup to three senior managers who would deal with pricing andto whom category managers report There are also ten-to-twelvecategory managers who are responsible for setting prices on allthe products within their category An additional two-to-fourpeople spend full time handling the implementation of pricechanges across retail outlets coordinating the printing and deliv-ery of price tags and handling pricing problems in the systemAnother ve-to-seven workers gather the data on competitorsrsquoprices and analyse both the competitorsrsquo data and the storersquos ownscanner data to put it in a form useable by managers makingpricing decisions Thus in total there are about 21ndash27 peopleworking at the corporate headquarters on price change decisionsAssuming $150000 as the average annual salary of the executiveof merchandising and senior managers $100000 for categorymanagers and $50000 for the rest the chainwide managerialcost falls in the neighborhood of $23ndash$29 million a year whichseems a substantial amount However note that these pricing de-cision are made for the entire chain and therefore the costs perstore are signicantly less especially for the larger chains Forexample using $29 million as the upper bound the additionalannual menu cost per store for Chains AndashD which on averageoperate about 400 stores each averages about $7250 which ismuch lower than expected and is due to the centralization of theprice change decisions in the chains we study17

signed to save the costs of corporate headquarter managerial time spent on pricechange decisions the ESL company did not measure this component of menucosts The estimates reported in this section are based on the information receivedfrom the ESL company executives

17 A decentralization of the price change process say by allowing the store-level managers to make price change decisions can change these gures tremen-dously For example consider the following thought experiment conducted using

QUARTERLY JOURNAL OF ECONOMICS808

Our menu cost measures also do not include the cost ofchanging prices of direct store delivery (DSD) products Theseproducts are almost completely handled by manufacturers in-cluding stocking monitoring inventories and setting and chang-ing prices18 We have data on the weekly frequency of pricechanges of DSD products in Chain E In an average week thereare 174 price changes of DSD products which is about 10 percentof the supermarketrsquos total weekly price changes Using the costof changing the price of a regular product $133 (see Section IVfor details) the annual cost of changing prices of the DSD prod-ucts in this chain roughly equals $1203419 Our menu cost mea-sures do not include these gures since we do not have similardata for the other chains20

III6 Total Menu Costs

The total annual menu costs reported for each chain perstore are listed in the last row of Table III As the table indicatesthe menu costs range from $91416 to $114188 for an average of$105887 per store per year21 Note that these menu cost mea-

the average annual per store gures for Chains AndashD Suppose that the supermar-ket chains decentralize the price change process by hiring for each store only one-quarter of the price change managing team while at the same time they com-pletely eliminate the corporate level team The resulting annual menu cost perstore would be $830887 ( 5 $105887 1 $725000) which would dwarf any of themeasurable menu cost gures we report in this study Even if the average storeonly hired just the merchandising manager at the annual cost of $150000 itwould still incur annual managerial cost of about $255887 ( 5 $105887 1$150000) In other words such a trivial decentralization would double the store-level menu costs This would indeed make the cost of price change decisions themost important component of menu cost

18 DSD products usually are high-volume fast-moving or perishable prod-ucts such as milk soda eggs bread dairy snacks etc In the chains we studyabout 10ndash20 percent of the products are of a DSD type but that share may reachas much as 40 percent of the products carried [Direct Store Delivery Work Groupet al 1995]

19 The process of changing prices of DSD and of regular products is similarBut with DSD products there are additional costs of the time spent on driving tothe store parking and setting up the price change process at each store

20 Our measures of menu cost also do not incorporate the cost of informingconsumers about price changes which can take a variety of forms such as newspa-per ads and inserts TV and radio ads in-store promotion signs etc Finally wehave no data on lost customer goodwill and damaged reputation caused by dis-crepancies between price tag and cash register [Okun 1981 Carlton and Perloff1994 Haddock and McChesney 1994]

21 The variation in the menu costs across the chains is mostly due to wagerate and labor-efciency variations Also note that since the supermarket chainsin our sample are similar in the size of their stores carry similar sets of productsand follow similar processes of price change and price change decisions it is rea-sonable to believe that the chains incur similar types of costs Therefore as notedunderneath Table III these menu cost measures are computed by replacing theunreported gures by the averages of the available values from the other chains

THE MAGNITUDE OF MENU COSTS 809

sures include only the components we could accurately measurein dollar terms which are discussed in subsections III1ndashIII4

IV ITEM PRICING LAWS AND MENU COSTS

In this section we provide evidence on the menu costs for anadditional chain (Chain E) which unlike the other four chainsoperates in a state with an item pricing law The most importantaspect of item pricing laws is that they require a price tag on eachindividual item sold not just on the shelf which is what the otherfour chains in our sample do For example the item pricing lawin Connecticut requires that the grocers ldquoshall mark or cause tobe marked each consumer commodity which bears a UniversalProduct Code with its retail pricerdquo 22 From a menu cost perspec-tive the requirement of posting prices on every item (in additionto the shelf price tag) introduces additional costs in the processof changing prices

Although most of the steps involved in changing prices arethe same for both types of chains stores that are subject to itempricing laws have to undertake additional steps to obey this law23

The labor cost component of menu costs in Chain E totals $75127a year of which $49710 is the cost of the labor time spent onchanging the prices of individual items $3234 is the cost of thelabor time spent on shelf tag replacements and $22183 is thecost of the labor time spent on sign changes (see Table III)24 Anadditional $44168 is spent annually putting prices on new itemsas they are brought to the shelves Although we do not includethis last gure in our menu cost measures because we do not haveinformation on how much of it is due to price change activity andhow much due to just pricingmdashthese costs are clearly a directconsequence of the item pricing law The printing and deliverycost of price tags and price signs are $7644 and the mistake

22 Public Act No 75ndash391 An Act Concerning Pricing of Consumer Merchan-dise [Public Acts of the State of Connecticut 1975 Vol 1 p 390]

23 These steps which are in addition to the regular steps undertaken toreplace price tags on the shelves include (1) obtaining item price tags (2) settingup workstations (3) locating the product (4) removing an item from the shelf (5)removing old price tag (6) setting marking gun (7) applying new price tag and(8) returning the item back to the shelf

24 Since we do not have a measure of the cost of labor time spent on signchanges and the cost of in-store managerial supervision time for this chain weuse the average of the chains that report them (A and D) Note also that thehourly wage rate of $907 paid by Chain E is lower than the hourly wage of about$1400ndash$2000 paid by Chains AndashD

QUARTERLY JOURNAL OF ECONOMICS810

25 Further note that the chains with smaller menu costs are likely tochange their prices more frequently which suggests that the gures of the totalannual menu costs understate the differences between Chain E and the otherchains Indeed despite the large difference in the menu cost per price change thetotal annual menu costs per store for Chain E ($109036) are more comparable tothose of Chains AndashD ($105887)

26 In calculations that follow we use industry averages because (1) thechains did not share this proprietary information with us and (2) we were re-quired to keep the identity of these chains condential as some of these numbersare detailed enough to enable some readers to identify the chains under study

costs are $20799 These gures along with the amount of $5466for the cost of in-store managerial supervision time yield totalannual menu costs of $109036 per store

Although the magnitude of the total annual menu costs seemsimilar to the other four chains note that the average weeklyfrequency of price changes in Chain E is only 1578 which is only403 ( 5 15783916) percent of the price changes made by theother four chains Thus the average menu cost per price changefor Chain E is $133 (see Table IV last row) In contrast the corre-sponding gures for Chains AndashD average $052 Hence the menucosts per price change incurred by the supermarket chain facingitem pricing laws are more than two and a half times the amountincurred by chains that are not subject to this law25 Overallthese ndings suggest that legal restrictions of the type of itempricing laws can have a signicant impact on the menu costs in-curred by sellers

V SIGNIFICANCE OF THE MENU COSTS

The next natural question to ask is how important are thesecosts To address this question we (1) provide several relativemeasures of the menu costs (2) discuss the effect of the menucosts on supermarketsrsquo price change activity and (3) discuss mac-roeconomic implications by relating our ndings to the existingtheoretical models of menu costs In each case we provide addi-tional evidence to help assess the importance of these menu costs

V1 Relative Measures of the Menu Costs

In order to assess the relative magnitude of the menu costsreported in Section IV we now present the menu cost gures rela-tive to the average store-level revenues and net prot margins26

In addition we present the menu cost gures per price changeThe annual average revenues of a large U S supermarket

chain of the type and size included in our sample is $15052716

per store27 According to the second row of Table IV the ratio ofmenu costs to revenues for Chains AndashD ranges between 061ndash076percent averaging 070 percent28 We relate the size of thesegures to the existing theoretical menu cost models in sub-section V3

Net prot margin which measures the revenues minus allcosts is approximately 1ndash3 percent of revenues for these chains[Montgomery 1994] so we use 2 percent as a working averageThe reason for the low prot rate in this industry is the intensecompetition [Calatone et al 1989] especially at the regional level[Chevalier 1995] which has been increasing since the early 1990s[Progressive Grocer November 1992 p 50] It follows that theaverage store protability for these chains equals $301054 peryear Therefore the ratio of total menu cost to net margin forChains AndashD ranges between 304ndash379 percent for an average of352 percent Thus the menu costs we report in this study repre-sent a signicant share of supermarketsrsquo prots

Another way to look at the menu cost gures we report is toexpress them relative to the frequency of price changes In thelast row of Table IV we present the menu cost gures per pricechange for each chain As the table indicates the cost of changinga price in Chains AndashD ranges between $046ndash$068 for an averageof $052 For Chain E the gure is substantially larger $133 perprice change29 These gures are lower than the estimated cost of

27 This is the average of two different estimates $12945432 and$17160000 The source of the rst gure is internal record of a supermarketchain of the type and size studied here The second gure comes from Supermar-ket Business [1993 p 52]

28 We also measured the menu costs in terms of controllable operating ex-penses (which are the portion of costs that the retailer has direct control over andtherefore are often the costs that the retailer is most focused on managing) andgross margins (which measure the supermarket revenues minus direct cost of theproducts it sells) We nd that the menu costs comprise 313 percent of controlla-ble operating expenses and 281 percent of gross margins at these chains on aver-age Finally if we measure the menu costs relative to the number of productscarried per store (about 25000) then we nd that the menu costs per productaverage $423 for Chains AndashD See Table IV and its footnotes for details

29 We can also try to express the menu cost gures relative to the numberof individual items sold by these chains each year (Note the difference betweennumber of products carried and number of items sold As an example a TartarControl Crest 8oz would be considered a product carried and 300 units of themsold per year would be considered number of items sold) Using $170 as the aver-age price of all the products sold we nd that the menu cost per item sold for thefour chains is in the range of $00103ndash$00129 for an average of $00119 (see TableIV second to last row) To see the relative magnitude of these gures note thataccording to Berkowitz Kerin and Rudelius [1986 p 319] the goal of the super-market chains of the type we study ldquo is to make 1 penny of prot on each dollarof salesrdquo Thus menu cost per item sold when adjusted for the average price

THE MAGNITUDE OF MENU COSTS 813

$200ndash$300 per price change reported by Slade [1996a] Thereare several possible reasons for this (1) our menu cost gures arebased on actual measurements of the resources that go into theprice change process whereas she estimates menu costs econo-metrically as model coefcients using a mix of store-level priceand aggregate cost data (2) we cover 25000 products that thesupermarkets carry rather than a single product category (3) ourmenu cost gures do not include all components of menu costsand (4) there could be differences in wage rates that may be im-portant given the signicance of the labor cost component inmenu costs

V2 The Effect of Menu Costs on the Price Change Activity of theSupermarkets

In this section we present evidence which suggests that thesemenu costs may be forming a barrier to price change activity Tobegin with consider the effect of the item pricing law on the pricechange activity of Chain E The data on the weekly frequency ofprice changes in each chain are displayed in the last two rows ofTable I According to these gures the average weekly frequencyof price changes in Chain E is only 1578 Thus on average ChainE changes the prices of only 631 percent of its products eachweek In contrast the average weekly frequency of price changesat Chains AndashD ranges from 3223 to 4316 for the four-chain aver-age of 3916 price changes weekly So Chains AndashD change priceson 1289 to 1726 percent of their products each week yielding afour-chain average of 1566 percent Thus Chain E which facesthe item pricing law changes prices only about one-third timesas frequently as do Chains AndashD30

Moreover within Chain E there are 400 products that areexempt from the item pricing law and thereby face lower menucosts We nd that there are an average of 83 weekly pricechanges for these products yielding 21 percent of these productschanging prices So within Chain E they change prices over threetimes as frequently for products with lower menu costs than for

roughly equals one-half of their target net prot per item which seemssubstantial

30 However note that our comparison of the two types of chains may not becompletely ceteris paribus because these stores are located in different states andtherefore there may be other chain-specic factors (in addition to item pricinglaws) that distinguish these stores We do not have any specic information onthese differences We do know however that the stores in these chains are similarin size and carry similar sets of products

QUARTERLY JOURNAL OF ECONOMICS814

the products with higher menu costs Note that this nding is onthe price change activity within the same chain offering almost anatural experiment on the impact of menu costs on the chainrsquospricing behavior Hence we provide evidence both across chainsas well as across products within a chain that as the costs ofchanging price go up the frequency of price changes goes downThus the menu costs we nd are signicant enough to affect thechainrsquos price change practice

We also have additional evidence from Chains A B and Dabout these menu costs being a barrier to certain price changesand it is summarized in Table V According to the Price Manage-ment Department of Chain A the chain experiences cost in-creases on 860 products in an average week to which it wouldlike to react with a price increase31 However on average 22 per-cent of these price increases are not implemented immediatelybecause the cost of changing prices for these products is too highto make it economically worthwhile Figures of the same magni-tude were reported by other chains For example Chain D experi-ences cost increases for 961 products in an average week Out ofthese the chain adjusts prices of only 633 products The re-maining 34 percent of the prices are left unadjusted because ofthe menu costs Similarly Chain B nds it economically ineffi-cient to adjust prices of 508 ie 30 percent of its products eachweek because of menu costs This provides additional evidencethat the menu costs incurred by these chains are preventing priceadjustments to some costs changes leading to price rigidities ofthe products involved32 Note that although we do not have simi-lar data for Chain E we would expect signicantly lower num-bers on this measure at that chain These gures also suggest anupper bound on the benet of complete price exibility under thecurrent pricing practice of weekly price adjustments Howeverif new technologies (eg ESL systems) and new pricing prac-tices (eg a decentralization of the price change decisions) are

31 Our data contain information only on the frequency of cost increasesAlthough it is more than likely that the supermarkets are experiencing cost de-creases as well our data set contained no information on such decreases

32 Menu costs may even be playing a role in the observed movement towardpricing strategies that rely on fewer price changes such as EDLP [Blattberg andNeslin 1989 Lattin and Ortmeyer 1991 Marketing News April 13 1992 p 8]According to Progressive Grocer [November 1992 p 50] ldquoA growing number ofoperators say they have switched from high-low pricing [to EDLP] They cite theinefciencies of making frequent price changes rdquo Similarly Hoch Dreze andPurk [1994 p 16] state that EDLP lowers operating costs by lowering ldquo in-store labor costs because of less frequent changeovers in special displaysrdquo

adopted allowing a fundamental change in the way the pricingmechanism is currently set the managers could consider morefrequent price change activity (eg multiple times each week) asmenu costs go down

In this paper we measure the menu costs at the chainsrsquo cur-rent level of price change activity It may be worthwhile to specu-late on the shape of the cost function relating menu costs to thefrequency of price changes by assessing how these costs wouldchange if the price change activity were to increase or to decreaseIt seems likely that many of the costs we report in this paper will(approximately) change linearly with additional price changeswithin the current range of price changes the chains are under-taking (plus or minus perhaps a thousand per week) For ex-ample the labor costs associated with changing a shelf price tagcosts of verifying price changes and the costs of mistakes oc-curring during this process all increase linearly with the fre-quency of price changes This is because most of the time-consuming steps involved in the price change process must berepeated each time an additional shelf price tag is changed (seeTable II) Further we were unable to nd many tasks that gener-ated signicant returns to scale It is unclear what cost savingsare available if the price change activity drops substantially be-

low the levels it is at now Clearly if price changes were nearzero or done less frequently than weekly (say monthly) therecould be major differences in these costs

What is less clear is how these costs would change at moreextreme levels of price change activity With less frequent pricechanges the menu costs could probably be reduced signicantlyalthough the cost of deciding what prices to set initially and thecost of putting the initial shelf price tags would still remain as alower bound of the menu cost However for achieving more priceexibility by changing prices more frequently (ie multiple timeseach week) substantial changes must be undertaken At presentthe supermarket chains are set up to make the majority of theirprice changes on a weekly basis with the appropriate systems inplace to make this process most efcient For example in orderto save costs and to have higher quality price tags (eg withcolor more details greater clarity glossy etc) the chains oftensend new price tag requests to a printing shop which takes threedays to print and deliver the labels to each store Then giventhe large number of price changes taking place and the goals ofminimizing customer disruptions and labor costs (such as over-time pay) and coordinating with advertised price promotions theprices are changed in the store over a two-to-three-day period (seeTable VI) The combination of these schedule and built-in lags isacceptable under the current practice of changing prices weeklybut would have to be adjusted dramatically to allow for signifi-cantly more frequent price changes on a regular basis

Perhaps even more imposing are the costs of changing themanagerial costs associated with the current weekly system ofprice changes The process of pricing at this organizational levelis not a self-contained activity taking place in isolation from otheroperations of the supermarket management Rather it is a partof a larger system of business decisions and operations The cur-rent process of operations (such as data collection and theiranalysis management meetings coordination of the decisionsacross functional areas etc) is set up to function on a weeklybasis33 Further these management accounting and logisticssystems are currently built around a tremendous amount of in-

35 If the supermarket chains indeed restructure the entire price change pro-cess and begin to change prices much more frequently (say two-to-three times aweek) on a regular basis then the shape of this cost function could change in anunpredictable way

V3 Relating Our Findings to the Existing Theoretical Models ofMenu Costs

In order to assess the magnitude of these menu cost guresin the context of the existing theoretical menu cost literatureconsider the following calculation experiments done within theframework of two theoretical menu cost models Blanchard andKiyotaki [1987] study a general equilibrium menu cost modelwith monopolistic competition and with unit elasticity of aggre-gate demand with respect to real money balances According totheir calculations menu costs of the magnitude of 008 percent ofrevenues which they consider ldquovery smallrdquo may be sufcient toprevent adjustment of prices Ball and Romer [1990] conductsimilar calculations in the framework of a model with imperfectcompetition and menu costs They nd that for plausible markupand labor elasticity parameter values menu costs needed to pre-vent price adjustment are 070 percent of revenues which as theysuggest are nonnegligible For smaller menu costs eg 004 per-cent of the revenue which Ball and Romer consider ldquotrivialrdquo im-plausibly large values of markup and labor elasticity parametersare needed to prevent price adjustment to monetary shocks

According to the gures in Table IV the reported menu costto revenues ratio for Chains AndashD averages 070 percent rangingfrom 061 percent to 076 percent These are signicantly largerthan the ldquotrivialrdquo 004 or 008 percent gures mentioned abovesuggesting that the menu cost gures we nd here are nontrivialFurther under the model and parameter values considered byBlanchard and Kiyotaki [1987] the menu cost gures we nd arehigher than the theoretical minimum needed to form a barrier toprice adjustments Under the model and parameter values con-sidered by Ball and Romer [1990] the reported menu costreve-nue ratio for all but one chain reaches or crosses the theoreticalthreshold of 070 needed to form a barrier to price adjustmentsThe existence of numerous unmeasured menu cost componentsdiscussed in subsection III5 also raises the possibility that theactual menu costs incurred by these chains are signicantlyhigher than that threshold This suggests that the menu costs wereport may be large enough to form a barrier to nominal priceadjustments when interpreted in the context of these models

An issue of interest in this literature is time-dependent ver-sus state-dependent pricing rules (see for example Caplin andLeahy [1991]) The evidence from our data set on the timing of

THE MAGNITUDE OF MENU COSTS 819

price changes suggests that the price change decisions in thesesupermarkets have a strong time-dependent price-setting ele-ment36 For example according to Table VI the prices in Chain Aare changed weekly according to the following schedule the pricechanges of general merchandise that is advertised is done Satur-day nights grocery and produce prices are changed Sundaynights the rest of the general merchandise prices are changed onMonday nights and the prices of advertised grocery items arechanged on Tuesday nights Thus as the gures in Table VI indi-cate over 96 percent of the price changes are done during Sundayand Monday nights However this does not imply that state-dependent pricing rules are unimportant Even if price changesacross product categories follow a prescheduled weekly time ta-ble the prices of which products to change is likely to be a state-dependent decision For example it could depend on changes insupply and demand conditions such as competitorsrsquo price changedecisions Indeed Levy Dutta and Bergen [1996] use retailstore-level orange juice price and cost data to demonstrate thatthe extent of price response to cost shocks that is the extent ofprice rigidity may depend on the nature of supply shocks37

We do not want to overstate the usefulness of our data fordirectly addressing the issue of monetary nonneutrality On onehand authors such as Caplin and Spulber [1987] have demon-strated that under certain conditions individual price rigiditymay not be sufcient for aggregate price rigidity but unfortu-nately our data do not speak directly to this issue38 On the otherhand authors such as Akerlof and Yellen [1985] Mankiw [1985]Parkin [1986] and Caplin and Leahy [1997] have shown that even

36 Danziger [1983] Caballero [1989] and Ball and Mankiw [1994] suggestthat time-dependent price adjustment of the type documented here can be optimalif the cost of gathering information about the state exceeds the cost of making theprice adjustment itself

37 We also considered the possibility of convexities in the cost of changingprices Our data do not suggest many convexities since the labor time spent inthe price tag change process the cost of printing and delivering price tags andin-store supervision time do not change with the size of a price change The onlymeasurable component of menu costs that could be convex is the cost of mistakesmade the larger the price change the higher the probability of a customer notic-ing the mistake and the larger the amount required to be refunded as compensa-tion Among the unmeasured components of menu cost the cost of corporatemanagerial time may increase with the size of a price change because larger pricechanges may require more serious consideration

38 Also see Balke and Wynne [1996] and Bryan and Cecchetti [1996] Sincewe do not have measures of how menu costs change over time our data also havelittle to say about time variation in menu costs or about the relationship betweenmenu costs and ination which during the period of the data collection (1991ndash1992) averaged about 3 percent annually

QUARTERLY JOURNAL OF ECONOMICS820

small menu costs can be relevant since they may be sufcient togenerate substantial aggregate nominal rigidity and thus largebusiness cycles Therefore as Blinder [1994] Kashyap [1995]and Slade [1996a] emphasize it is important to search for directevidence that such costs are indeed present at the micro level Bydirectly identifying documenting and measuring the magnitudeof menu costs at the store level we are taking an important stepin that direction

VI CONCLUSION AND FUTURE RESEARCH

Our main contribution is that we provide direct microeco-nomic evidence on the actual magnitude of menu costs for fourlarge U S retail supermarket chains The annual menu costs perstore at these chains average $105887 comprising 070 percentof revenues 352 percent of net prot margins and $052 perprice change on average

Further we provide evidence which suggests that thesemenu costs may be forming a barrier to price changes Specifi-cally we show that (1) supermarket chains not subject to itempricing law change prices two and a half times more frequentlythan the chain that is subject to the law (2) within the chain thatis subject to the item pricing law they change prices over threetimes as frequently for products that are exempt from this lawthan for the products which are subject to this law and (3) wend that these chains do not adjust prices of up to one-third ofthe products for which they face cost increases because of menucost considerations

When we relate these ndings to the existing theoreticalmodels of menu costs we conclude that the magnitude of menucosts we nd is large enough to be capable of having macroeco-nomic signicance Specically when considered in the context ofthe theoretical menu cost models of Blanchard and Kiyotaki[1987] and Ball and Romer [1990] we nd that the menu costgures we report are ldquonontrivialrdquo and their relative magnitudescross the minimum theoretical threshold needed to form a barrierto price adjustments

Despite the high relative magnitude of the marginal cost ofchanging price that we found the data still indicate frequentweekly price changes This is because of the high marginal bene-t of changing price which is due to the erce competition foundin the retail supermarket industry That marginal benets may

THE MAGNITUDE OF MENU COSTS 821

outweigh the marginal costs of changing prices in this industryhowever does not rule out the possibility that menu costs of themagnitude we nd here can create substantial nominal rigidityin other industries or markets In less competitive industries andmarkets menu costs of the type and magnitude we documenthere are likely to have a bigger impact on the frequency of priceadjustment and consequently on the degree of price rigidity

At a minimum the direct dollar measures of menu costs wereport here can be used as a starting point for future research onmeasuring their magnitude in other industries and establish-ments We anticipate that these menu costs will be similar inother markets which rely on posted prices (such as drugstoresdepartment stores etc) because the steps involved in the pricechange process are likely to be similar What may differ are thefrequency of price changes and the labor wage rates at thesestores For example since supermarket chains change thousandsof prices each week the total annual menu costs incurred bythese chains per store are likely to be high in comparison to otherretail formats such as chain drugstores or department storesThere are however a variety of industries for which the stepsinvolved in changing prices would be signicantly different fromthose reported in our study For example business-to-businesssales which often rely on a sales force will require changes in thelist price sheets changes in the instructions to the sales forcewhich may include education and discussion with the salespeoplein the company and so forth These business-to-business pricesalso often have more complex pricing schemes including quantitydiscounts bundling and individually negotiated prices As an-other example the composition of the cost of changing the news-stand prices of magazines [Cecchetti 1986] or the prices ofproducts sold through catalogs [Kashyap 1995] are different frommany of the menu cost components we discuss here Further thending that a centralization of pricing decisions makes the store-level managerial component of menu cost relatively small sug-gests that the managerial menu costs likely are highest insettings where price change decisions are decentralized Thus fu-ture empirical work should look at menu cost and its compositionin a variety of other industries markets and products with bothcentralized as well as decentralized price change decisions in or-der to see whether the magnitude of these costs can be general-ized and benchmarks can be established Further there aretechnological changes taking place in this and other industries

that promise to alter the structure of menu costs which deserveattention At the theoretical level our ndings suggest that it maybe worthwhile to explore models which incorporate the idea ofitem pricing laws as an additional component of menu costs

THE MAGNITUDE OF MENU COSTS 825

the rm had an incentive to overestimate the magnitude of themenu costs in order to sell the ESL system We think howeverthat the menu cost measures we report in this paper are not sub-ject to signicant biases of this sort for a number of reasonsFirst the ESL people measured and documented all price changeactivities jointly with the supermarket employees using the wagegures provided by the supermarket management Second timeand motion measurements of the type used for measuring themenu costs we report here are routinely done by supermarketchains themselves in order to assess the efciency of their pricechange processes The supermarket managers compared theirgures to the ESL company gures and found them to be similarFurther these gures were presented to upper management ofthese chains and were found to be representative of their coststructures In fact the validity of the menu cost measures con-structed by the ESL company was never disputed If there wasany disagreement between the ESL company and the supermar-ket chains it was about the size of the savings the ESL systemwould provide not about the accuracy of the menu cost measure-ments7 Further we looked at these reports and searched for g-ures that could be biased upward There were a few such as lossof goodwill costs and inventory holding costs and to be on theconservative side we did not include them in our measures ofmenu costs Thus we only report gures for which we could seeno upward bias Finally note that the menu cost gures we reportare clearly biased downward because we were unable to measurein dollar terms several components of menu costs and thus theyare not included in our gures (see subsection III5 for details)

Table I displays some general information about the super-market chains we study their pricing strategy and informationabout the frequency of weekly price changes the stores under-take The chains involved in this study are all large U S super-market chains from different regions in the United Statesranging from the Northeast to the West Coast and operating anaverage of 400 stores each At the request of these retailers wewill keep the companies in this study anonymous but they areall large multistore chains that seem reasonably representativeof large supermarket chains currently selling in the United

a HL (HighLow) and EDLP (Every Day Low Price) refer to the general pricing strategy followed by theretail chain Under the EDLP strategy the retailer rsquos prices are low for extended periods of time and there-fore it will offer fewer promotional sales or discounts Under the HL pricing strategy in contrast the retail-errsquos prices are higher and the retailer tends to offer more frequent discounts through sales and promotionsSee the text for more details

b The share of products for which prices change on an average week is the ratio of number of pricechanges per store per week to 25000 The latter is the average number of products carried per store eachweek

States These chains are similar in the variety selection andquantity of the products they carry Supermarket chains of thistype make up $310146666000 in total annual sales which is863 percent of total supermarket chain sales in 1992 [Supermar-ket Business 1993] so the chains in our sample are representativeof a major class of the retail grocery trade

According to the second row in Table I the number of weeklyprice changes in Chains AndashD ranges from 3223 to 4316 for anaverage of 3916 per store8 The variation in the number of weeklyprice changes across the chains is due in large part to their choiceof pricing strategy Chains A and B follow a highlow (HL) pricestrategy while Chains C and D follow an everyday-low-pricestrategy (EDLP) Under the EDLP strategy the retailerrsquos pricesare low for an extended period of time and therefore it will offerfewer promotional sales or discounts Under the HL pricing strat-egy in contrast the retailerrsquos prices are higher and the retailertends to offer more frequent discounts through sales and promo-tions The pricing strategy therefore will have an effect on thefrequency of price changes observed In particular we would ex-

pect EDLP stores to have less frequent price changes in compari-son to the HL stores Indeed according to Table I Chains A andB tend to have a higher number of weekly price changes (4278and 4316 respectively) than Chains C and D (3846 and 3223respectively)

Supermarkets of the size we study tend to carry around25000 different items on a regular basis9 The last row in thetable presents the share of the 25000 products for which the su-permarket chains change their prices in a period of one weekThe average share for the four chains is 1566 percent

III ABSOLUTE MEASURES OF MENU COSTS

There are four components of menu costs that we are able tomeasure in dollar terms10 These are (1) the cost of labor requiredto change the shelf price tags (2) the cost of printing and deliv-ering new price tags (3) the cost of mistakes made during theprocess of changing prices and (4) the cost of in-store supervisiontime spent on implementing price changes

III1 Costs of the Labor Required to Change Shelf Prices

Figure I displays an overview of the steps involved in chang-ing prices at Chain A There are three main components in thelabor costs incurred by the chains (a) labor cost of tag changepreparation (b) labor cost of the tag change itself and (c) laborcost of verifying whether the price changes are done correctlywhich include tag change verication in-store resolution of pricemistakes and zone and corporate resolution of price mistakes11

9 The supermarkets often have about 40000 UPC codes in their computerdatabase records but internal studies undertaken by the ESL company indicatethat the supermarkets usually carry no more than 25000 products at any giventime The extra UPC codes are for seasonal or promotional sizes and packages ofproducts and for discontinued products

10 In this paper we only report measures of the marginal cost of changingprices The costs of putting a price tag for the rst time and other costs thatwould be included in the average cost are not included in the gures we reportOnly when discussing Chain E which is the chain subject to item pricing lawsdid we face the issue of cost of pricing (at the rst time) versus the cost of changinga price Since there was no clear way of separating the two types of costs thereported cost gure ($44168 in the second paragraph of Section IV) was excludedaltogether from our calculations Also see footnote 13

FIGURE IOverview of the Price Change Process

POS denotes Point of Sale and refers to the cash register or the database itis connected to or both For information on the various steps undertaken in eachstage of the price change process and the amount of the labor time spent on mosttime-consuming steps see Table II

Standard price tag changes which include the steps outlined onthe left-hand side of Figure I make up the majority of pricechanges in these chains Some price changes also require addi-tional price signs to be placed at different locations in the storesuch as on an end of aisle display or near the shelf12 These sign

12 These are usually related to the product being on promotion feature ad-vertising display or in-store sale such as ldquomanagerrsquos specialrdquo ldquotodayrsquos specialrdquoetc The steps involved in making sign changes are similar to price changes Themain differences are that (i) the time required for each of the steps in sign changes

changes add to the menu costs and they are outlined on theright-hand side of Figure I the sign change preparation actualsign changes and sign change verication boxes The bottom twoboxes in Figure I are additional menu costs related to the extrasteps taken in these stores to make sure the tag and sign changeshave been done correctly13

Table II lists each stage of the price change process the totalamount of time spent on each stage each week on average andthe number of tasks performed In addition the table identiessome of the main tasks performed in each stage as well as thefour most time-consuming tasks in each stage To compute thetotal labor time used in changing prices on a weekly basis wecombine the data collected through in-store time and motion ob-servations with information on the volume of products for whichprices are changed These weekly hours are multiplied by thewage rates (adjusted for fringe benets) of the employees used inthe price change process to get the total costs of labor required tochange prices

For the four supermarket chains in our study the total an-nual labor cost of changing the shelf price tags ranges from$40027 to $61414 per store for an average of $52084 (see therst row in Table III making up about 49 percent of the totalmenu costs on average The labor cost of changing the price signsrange from $16411 to $27955 per store for an average of$22183 (see the second row in Table III) making up almost 21percent of the menu costs on average Thus for the four super-market chains the total annual menu costs associated with thelabor required to change prices (shelf price tags and price signscombined) range from $62210 to $81703 per store for an annualaverage of $74267 This is the single largest component of themenu costs we report in this study making up about 701 percentof the total menu costs for these chains on average This shouldnot be surprising given that the most signicant portion of retail

are longer because they are in less standard locations and (ii) there are fewersign changes than standard shelf price tag changes

13 The menu cost measures we report do not include the cost of changingprices in cases where items are moved from shelf to shelf or where shelf space isreallocated by increasing the shelf space for some products at the expense of oth-ers However they do include the cost of pricing new products when they are rstintroduced While this could bias the menu cost measures upward since it reallycaptures the cost of pricing rather than the cost of changing price the size of thisbias is marginal due to the small number of new products For example accordingto ESL company executives the number of new products introduced at thesechains each week ranges from 20 to 100 approximately In comparison to the num-ber of products for which prices are changed each week (3223ndash4316) the biasis negligible

grocery operating expenses is labor costs [Hoch Dreze andPurk 1994]14

III2 Costs of Printing and Delivering New Price Tags

There are direct costs associated with printing and deliv-ering the price and sign tags The order must be recorded andprocessed at the chain sent to the printer recorded and pro-cessed at the printer printed packaged and then delivered toeach store The cost per tag is usually quite low $0017 per tagat Chain A which includes stock costs of $00118 per tag impres-sion and data center operator costs of $00037 per tag and mailroom handling costs of $00010 per tag There are however manyprice changes undertaken each week In total the costs of print-ing and delivering the price and sign tags range from $3048 to$10018 averaging $6014 per store per year (see Table III)These costs comprise less than 6 percent of the total menu costswe report

III3 Costs of Mistakes Made in the Process of Changing Prices

Despite the labor put into checking to make sure that theprice changes are done correctly there are still many price mis-takes that are not caught until customers discover them through-out the week and these mistakes impose costs on the chainClearly the costs associated with these errors must be consideredwhen deciding whether to change prices or not and therefore area relevant dimension of menu costs These mistakes can occur sooften that they were a feature of a Dateline segment on U Ssupermarket chains [NBC April 1992] and an article in MoneyMagazine [April 1993] Both the Money Magazine article andGoodstein [1994] report that on average 10 percent of the prod-ucts they examined had price mistakes A more recent study bythe Federal Trade Commission [1996] reports a total error rate ofabout 5 percent

The menu costs associated with these mistakes include lost

14 Our measure of labor cost may overstate the true costs of changing pricesif supermarkets hoard labor to save hiring and ring costs However this is notlikely to be the case for several reasons First the labor costs of changing priceswe report are based on actual measurements of the minimum amount of time andlabor required to accomplish the task rather than on the number of employeeshired to change prices at the store Second the adjustment in the amount of laboris usually done through hours worked which makes cost of hiring and ring lessrelevant And third the workers on the oor are routinely moved from task totask according to the need These tasks include stocking cleaning price changingcustomer service etc The workers employed by supermarket chains are alwaysbusy and so the opportunity cost of changing price is not zero Therefore laborhoarding is not likely to be an important factor in our measurements

QUARTERLY JOURNAL OF ECONOMICS806

cashier time to correct the errors scan guarantee refunds andinventory mistakes associated with incorrect price tags15 Lostcashier time is measured here in terms of wage payments Scanguarantee refunds are additional price reductions beyond the er-ror or additional items given away for free because of the mis-take Finally the inventory mistakes costs we report include onlythe cost of stockouts which occur when shelf price is lower thanintended

The mistake costs were available at Chains A C and D andthey range from $19135 to $20692 for an average of $20140 perstore annually (see Table III) These costs are the second largestcomponent of menu costs in our study comprising about 19 per-cent of the total

III4 Costs of In-Store Supervision Time Spent on ImplementingPrice Changes

Managers at the store level spend time overseeing imple-menting and troubleshooting the price change process OnlyChains A and B had a measure of the menu costs associated withthis in-store supervision time and both of these came from a self-reported number of hours spent on changing prices by the manag-ers at these chains The hours spent on changing prices were thesame across the chains approximately ve hours per week Thusthe menu costs for in-store supervision time came to $4241 and$6692 per store annually for Chains A and B respectively (seeTable III) These costs comprise less than 6 percent of the totalmenu costs we report in this paper However notice that thesemeasures do not include the cost of the management time spenton price change decisions made at corporate headquarters whichis discussed next

III5 Components of Menu Costs We Are Unable to Measure inDollar Terms

Our data set does not contain the exact dollar measures ofsome menu cost components One such component is the cost ofcorporate management time spent on price change decisions16 In

15 Other likely costs of price mistakes that we do not consider explicitlybecause we are unable to measure them in dollar terms are legal problems (whenthe scanner price is higher than the shelf price) loss in customer goodwill anddecreased protability (when the scanner price is lower than the shelf price)

16 It has been suggested that the cost of managerial decisions is one of themost important components of menu cost See for example Ball and Mankiw[1994] Kashyap [1995] and Meltzer [1995] Since the ESL system was not de-

THE MAGNITUDE OF MENU COSTS 807

the supermarket chains we study prices are generally set at cor-porate headquarters in a weekly meeting where the manager incharge of setting prices looks at a variety of information including(a) any manufacturer wholesale price changes promotions andother related issues (b) past sales for this product and (c) com-petitorsrsquo prices Based on this information and on discussionswith other managers the price-setting manager decides whetherto change prices and if so by how much

To estimate the magnitude of these managerial componentsof the menu costs consider the following In an average chainthere is at least one executive of merchandising who devotesmost of hisher time to pricing decisions In addition there areup to three senior managers who would deal with pricing andto whom category managers report There are also ten-to-twelvecategory managers who are responsible for setting prices on allthe products within their category An additional two-to-fourpeople spend full time handling the implementation of pricechanges across retail outlets coordinating the printing and deliv-ery of price tags and handling pricing problems in the systemAnother ve-to-seven workers gather the data on competitorsrsquoprices and analyse both the competitorsrsquo data and the storersquos ownscanner data to put it in a form useable by managers makingpricing decisions Thus in total there are about 21ndash27 peopleworking at the corporate headquarters on price change decisionsAssuming $150000 as the average annual salary of the executiveof merchandising and senior managers $100000 for categorymanagers and $50000 for the rest the chainwide managerialcost falls in the neighborhood of $23ndash$29 million a year whichseems a substantial amount However note that these pricing de-cision are made for the entire chain and therefore the costs perstore are signicantly less especially for the larger chains Forexample using $29 million as the upper bound the additionalannual menu cost per store for Chains AndashD which on averageoperate about 400 stores each averages about $7250 which ismuch lower than expected and is due to the centralization of theprice change decisions in the chains we study17

signed to save the costs of corporate headquarter managerial time spent on pricechange decisions the ESL company did not measure this component of menucosts The estimates reported in this section are based on the information receivedfrom the ESL company executives

17 A decentralization of the price change process say by allowing the store-level managers to make price change decisions can change these gures tremen-dously For example consider the following thought experiment conducted using

QUARTERLY JOURNAL OF ECONOMICS808

Our menu cost measures also do not include the cost ofchanging prices of direct store delivery (DSD) products Theseproducts are almost completely handled by manufacturers in-cluding stocking monitoring inventories and setting and chang-ing prices18 We have data on the weekly frequency of pricechanges of DSD products in Chain E In an average week thereare 174 price changes of DSD products which is about 10 percentof the supermarketrsquos total weekly price changes Using the costof changing the price of a regular product $133 (see Section IVfor details) the annual cost of changing prices of the DSD prod-ucts in this chain roughly equals $1203419 Our menu cost mea-sures do not include these gures since we do not have similardata for the other chains20

III6 Total Menu Costs

The total annual menu costs reported for each chain perstore are listed in the last row of Table III As the table indicatesthe menu costs range from $91416 to $114188 for an average of$105887 per store per year21 Note that these menu cost mea-

the average annual per store gures for Chains AndashD Suppose that the supermar-ket chains decentralize the price change process by hiring for each store only one-quarter of the price change managing team while at the same time they com-pletely eliminate the corporate level team The resulting annual menu cost perstore would be $830887 ( 5 $105887 1 $725000) which would dwarf any of themeasurable menu cost gures we report in this study Even if the average storeonly hired just the merchandising manager at the annual cost of $150000 itwould still incur annual managerial cost of about $255887 ( 5 $105887 1$150000) In other words such a trivial decentralization would double the store-level menu costs This would indeed make the cost of price change decisions themost important component of menu cost

18 DSD products usually are high-volume fast-moving or perishable prod-ucts such as milk soda eggs bread dairy snacks etc In the chains we studyabout 10ndash20 percent of the products are of a DSD type but that share may reachas much as 40 percent of the products carried [Direct Store Delivery Work Groupet al 1995]

19 The process of changing prices of DSD and of regular products is similarBut with DSD products there are additional costs of the time spent on driving tothe store parking and setting up the price change process at each store

20 Our measures of menu cost also do not incorporate the cost of informingconsumers about price changes which can take a variety of forms such as newspa-per ads and inserts TV and radio ads in-store promotion signs etc Finally wehave no data on lost customer goodwill and damaged reputation caused by dis-crepancies between price tag and cash register [Okun 1981 Carlton and Perloff1994 Haddock and McChesney 1994]

21 The variation in the menu costs across the chains is mostly due to wagerate and labor-efciency variations Also note that since the supermarket chainsin our sample are similar in the size of their stores carry similar sets of productsand follow similar processes of price change and price change decisions it is rea-sonable to believe that the chains incur similar types of costs Therefore as notedunderneath Table III these menu cost measures are computed by replacing theunreported gures by the averages of the available values from the other chains

sures include only the components we could accurately measurein dollar terms which are discussed in subsections III1ndashIII4

IV ITEM PRICING LAWS AND MENU COSTS

In this section we provide evidence on the menu costs for anadditional chain (Chain E) which unlike the other four chainsoperates in a state with an item pricing law The most importantaspect of item pricing laws is that they require a price tag on eachindividual item sold not just on the shelf which is what the otherfour chains in our sample do For example the item pricing lawin Connecticut requires that the grocers ldquoshall mark or cause tobe marked each consumer commodity which bears a UniversalProduct Code with its retail pricerdquo 22 From a menu cost perspec-tive the requirement of posting prices on every item (in additionto the shelf price tag) introduces additional costs in the processof changing prices

Although most of the steps involved in changing prices arethe same for both types of chains stores that are subject to itempricing laws have to undertake additional steps to obey this law23

The labor cost component of menu costs in Chain E totals $75127a year of which $49710 is the cost of the labor time spent onchanging the prices of individual items $3234 is the cost of thelabor time spent on shelf tag replacements and $22183 is thecost of the labor time spent on sign changes (see Table III)24 Anadditional $44168 is spent annually putting prices on new itemsas they are brought to the shelves Although we do not includethis last gure in our menu cost measures because we do not haveinformation on how much of it is due to price change activity andhow much due to just pricingmdashthese costs are clearly a directconsequence of the item pricing law The printing and deliverycost of price tags and price signs are $7644 and the mistake

22 Public Act No 75ndash391 An Act Concerning Pricing of Consumer Merchan-dise [Public Acts of the State of Connecticut 1975 Vol 1 p 390]

23 These steps which are in addition to the regular steps undertaken toreplace price tags on the shelves include (1) obtaining item price tags (2) settingup workstations (3) locating the product (4) removing an item from the shelf (5)removing old price tag (6) setting marking gun (7) applying new price tag and(8) returning the item back to the shelf

24 Since we do not have a measure of the cost of labor time spent on signchanges and the cost of in-store managerial supervision time for this chain weuse the average of the chains that report them (A and D) Note also that thehourly wage rate of $907 paid by Chain E is lower than the hourly wage of about$1400ndash$2000 paid by Chains AndashD

QUARTERLY JOURNAL OF ECONOMICS810

25 Further note that the chains with smaller menu costs are likely tochange their prices more frequently which suggests that the gures of the totalannual menu costs understate the differences between Chain E and the otherchains Indeed despite the large difference in the menu cost per price change thetotal annual menu costs per store for Chain E ($109036) are more comparable tothose of Chains AndashD ($105887)

26 In calculations that follow we use industry averages because (1) thechains did not share this proprietary information with us and (2) we were re-quired to keep the identity of these chains condential as some of these numbersare detailed enough to enable some readers to identify the chains under study

costs are $20799 These gures along with the amount of $5466for the cost of in-store managerial supervision time yield totalannual menu costs of $109036 per store

Although the magnitude of the total annual menu costs seemsimilar to the other four chains note that the average weeklyfrequency of price changes in Chain E is only 1578 which is only403 ( 5 15783916) percent of the price changes made by theother four chains Thus the average menu cost per price changefor Chain E is $133 (see Table IV last row) In contrast the corre-sponding gures for Chains AndashD average $052 Hence the menucosts per price change incurred by the supermarket chain facingitem pricing laws are more than two and a half times the amountincurred by chains that are not subject to this law25 Overallthese ndings suggest that legal restrictions of the type of itempricing laws can have a signicant impact on the menu costs in-curred by sellers

V SIGNIFICANCE OF THE MENU COSTS

The next natural question to ask is how important are thesecosts To address this question we (1) provide several relativemeasures of the menu costs (2) discuss the effect of the menucosts on supermarketsrsquo price change activity and (3) discuss mac-roeconomic implications by relating our ndings to the existingtheoretical models of menu costs In each case we provide addi-tional evidence to help assess the importance of these menu costs

V1 Relative Measures of the Menu Costs

In order to assess the relative magnitude of the menu costsreported in Section IV we now present the menu cost gures rela-tive to the average store-level revenues and net prot margins26

In addition we present the menu cost gures per price changeThe annual average revenues of a large U S supermarket

chain of the type and size included in our sample is $15052716

per store27 According to the second row of Table IV the ratio ofmenu costs to revenues for Chains AndashD ranges between 061ndash076percent averaging 070 percent28 We relate the size of thesegures to the existing theoretical menu cost models in sub-section V3

Net prot margin which measures the revenues minus allcosts is approximately 1ndash3 percent of revenues for these chains[Montgomery 1994] so we use 2 percent as a working averageThe reason for the low prot rate in this industry is the intensecompetition [Calatone et al 1989] especially at the regional level[Chevalier 1995] which has been increasing since the early 1990s[Progressive Grocer November 1992 p 50] It follows that theaverage store protability for these chains equals $301054 peryear Therefore the ratio of total menu cost to net margin forChains AndashD ranges between 304ndash379 percent for an average of352 percent Thus the menu costs we report in this study repre-sent a signicant share of supermarketsrsquo prots

Another way to look at the menu cost gures we report is toexpress them relative to the frequency of price changes In thelast row of Table IV we present the menu cost gures per pricechange for each chain As the table indicates the cost of changinga price in Chains AndashD ranges between $046ndash$068 for an averageof $052 For Chain E the gure is substantially larger $133 perprice change29 These gures are lower than the estimated cost of

27 This is the average of two different estimates $12945432 and$17160000 The source of the rst gure is internal record of a supermarketchain of the type and size studied here The second gure comes from Supermar-ket Business [1993 p 52]

28 We also measured the menu costs in terms of controllable operating ex-penses (which are the portion of costs that the retailer has direct control over andtherefore are often the costs that the retailer is most focused on managing) andgross margins (which measure the supermarket revenues minus direct cost of theproducts it sells) We nd that the menu costs comprise 313 percent of controlla-ble operating expenses and 281 percent of gross margins at these chains on aver-age Finally if we measure the menu costs relative to the number of productscarried per store (about 25000) then we nd that the menu costs per productaverage $423 for Chains AndashD See Table IV and its footnotes for details

29 We can also try to express the menu cost gures relative to the numberof individual items sold by these chains each year (Note the difference betweennumber of products carried and number of items sold As an example a TartarControl Crest 8oz would be considered a product carried and 300 units of themsold per year would be considered number of items sold) Using $170 as the aver-age price of all the products sold we nd that the menu cost per item sold for thefour chains is in the range of $00103ndash$00129 for an average of $00119 (see TableIV second to last row) To see the relative magnitude of these gures note thataccording to Berkowitz Kerin and Rudelius [1986 p 319] the goal of the super-market chains of the type we study ldquo is to make 1 penny of prot on each dollarof salesrdquo Thus menu cost per item sold when adjusted for the average price

THE MAGNITUDE OF MENU COSTS 813

$200ndash$300 per price change reported by Slade [1996a] Thereare several possible reasons for this (1) our menu cost gures arebased on actual measurements of the resources that go into theprice change process whereas she estimates menu costs econo-metrically as model coefcients using a mix of store-level priceand aggregate cost data (2) we cover 25000 products that thesupermarkets carry rather than a single product category (3) ourmenu cost gures do not include all components of menu costsand (4) there could be differences in wage rates that may be im-portant given the signicance of the labor cost component inmenu costs

V2 The Effect of Menu Costs on the Price Change Activity of theSupermarkets

In this section we present evidence which suggests that thesemenu costs may be forming a barrier to price change activity Tobegin with consider the effect of the item pricing law on the pricechange activity of Chain E The data on the weekly frequency ofprice changes in each chain are displayed in the last two rows ofTable I According to these gures the average weekly frequencyof price changes in Chain E is only 1578 Thus on average ChainE changes the prices of only 631 percent of its products eachweek In contrast the average weekly frequency of price changesat Chains AndashD ranges from 3223 to 4316 for the four-chain aver-age of 3916 price changes weekly So Chains AndashD change priceson 1289 to 1726 percent of their products each week yielding afour-chain average of 1566 percent Thus Chain E which facesthe item pricing law changes prices only about one-third timesas frequently as do Chains AndashD30

Moreover within Chain E there are 400 products that areexempt from the item pricing law and thereby face lower menucosts We nd that there are an average of 83 weekly pricechanges for these products yielding 21 percent of these productschanging prices So within Chain E they change prices over threetimes as frequently for products with lower menu costs than for

roughly equals one-half of their target net prot per item which seemssubstantial

30 However note that our comparison of the two types of chains may not becompletely ceteris paribus because these stores are located in different states andtherefore there may be other chain-specic factors (in addition to item pricinglaws) that distinguish these stores We do not have any specic information onthese differences We do know however that the stores in these chains are similarin size and carry similar sets of products

QUARTERLY JOURNAL OF ECONOMICS814

the products with higher menu costs Note that this nding is onthe price change activity within the same chain offering almost anatural experiment on the impact of menu costs on the chainrsquospricing behavior Hence we provide evidence both across chainsas well as across products within a chain that as the costs ofchanging price go up the frequency of price changes goes downThus the menu costs we nd are signicant enough to affect thechainrsquos price change practice

We also have additional evidence from Chains A B and Dabout these menu costs being a barrier to certain price changesand it is summarized in Table V According to the Price Manage-ment Department of Chain A the chain experiences cost in-creases on 860 products in an average week to which it wouldlike to react with a price increase31 However on average 22 per-cent of these price increases are not implemented immediatelybecause the cost of changing prices for these products is too highto make it economically worthwhile Figures of the same magni-tude were reported by other chains For example Chain D experi-ences cost increases for 961 products in an average week Out ofthese the chain adjusts prices of only 633 products The re-maining 34 percent of the prices are left unadjusted because ofthe menu costs Similarly Chain B nds it economically ineffi-cient to adjust prices of 508 ie 30 percent of its products eachweek because of menu costs This provides additional evidencethat the menu costs incurred by these chains are preventing priceadjustments to some costs changes leading to price rigidities ofthe products involved32 Note that although we do not have simi-lar data for Chain E we would expect signicantly lower num-bers on this measure at that chain These gures also suggest anupper bound on the benet of complete price exibility under thecurrent pricing practice of weekly price adjustments Howeverif new technologies (eg ESL systems) and new pricing prac-tices (eg a decentralization of the price change decisions) are

31 Our data contain information only on the frequency of cost increasesAlthough it is more than likely that the supermarkets are experiencing cost de-creases as well our data set contained no information on such decreases

32 Menu costs may even be playing a role in the observed movement towardpricing strategies that rely on fewer price changes such as EDLP [Blattberg andNeslin 1989 Lattin and Ortmeyer 1991 Marketing News April 13 1992 p 8]According to Progressive Grocer [November 1992 p 50] ldquoA growing number ofoperators say they have switched from high-low pricing [to EDLP] They cite theinefciencies of making frequent price changes rdquo Similarly Hoch Dreze andPurk [1994 p 16] state that EDLP lowers operating costs by lowering ldquo in-store labor costs because of less frequent changeovers in special displaysrdquo

adopted allowing a fundamental change in the way the pricingmechanism is currently set the managers could consider morefrequent price change activity (eg multiple times each week) asmenu costs go down

In this paper we measure the menu costs at the chainsrsquo cur-rent level of price change activity It may be worthwhile to specu-late on the shape of the cost function relating menu costs to thefrequency of price changes by assessing how these costs wouldchange if the price change activity were to increase or to decreaseIt seems likely that many of the costs we report in this paper will(approximately) change linearly with additional price changeswithin the current range of price changes the chains are under-taking (plus or minus perhaps a thousand per week) For ex-ample the labor costs associated with changing a shelf price tagcosts of verifying price changes and the costs of mistakes oc-curring during this process all increase linearly with the fre-quency of price changes This is because most of the time-consuming steps involved in the price change process must berepeated each time an additional shelf price tag is changed (seeTable II) Further we were unable to nd many tasks that gener-ated signicant returns to scale It is unclear what cost savingsare available if the price change activity drops substantially be-

QUARTERLY JOURNAL OF ECONOMICS816

low the levels it is at now Clearly if price changes were nearzero or done less frequently than weekly (say monthly) therecould be major differences in these costs

What is less clear is how these costs would change at moreextreme levels of price change activity With less frequent pricechanges the menu costs could probably be reduced signicantlyalthough the cost of deciding what prices to set initially and thecost of putting the initial shelf price tags would still remain as alower bound of the menu cost However for achieving more priceexibility by changing prices more frequently (ie multiple timeseach week) substantial changes must be undertaken At presentthe supermarket chains are set up to make the majority of theirprice changes on a weekly basis with the appropriate systems inplace to make this process most efcient For example in orderto save costs and to have higher quality price tags (eg withcolor more details greater clarity glossy etc) the chains oftensend new price tag requests to a printing shop which takes threedays to print and deliver the labels to each store Then giventhe large number of price changes taking place and the goals ofminimizing customer disruptions and labor costs (such as over-time pay) and coordinating with advertised price promotions theprices are changed in the store over a two-to-three-day period (seeTable VI) The combination of these schedule and built-in lags isacceptable under the current practice of changing prices weeklybut would have to be adjusted dramatically to allow for signifi-cantly more frequent price changes on a regular basis

Perhaps even more imposing are the costs of changing themanagerial costs associated with the current weekly system ofprice changes The process of pricing at this organizational levelis not a self-contained activity taking place in isolation from otheroperations of the supermarket management Rather it is a partof a larger system of business decisions and operations The cur-rent process of operations (such as data collection and theiranalysis management meetings coordination of the decisionsacross functional areas etc) is set up to function on a weeklybasis33 Further these management accounting and logisticssystems are currently built around a tremendous amount of in-

34 For example under the current system a chainwide category manageroperating at the corporate headquarters needs to study and assess numerouspieces of detailed information such as competitorsrsquo price and sale information fromthe last week the past weekrsquos sales at the own chain manufacturersupplier pro-motions wholesale price reductions coop allowances new product offerings shelfspace decisions coordination with newspaper advertising logistics at the ware-houses as well as at each store store differences in terms of customer characteris-tics and competitive environments productshelf selection and layout etc

35 If the supermarket chains indeed restructure the entire price change pro-cess and begin to change prices much more frequently (say two-to-three times aweek) on a regular basis then the shape of this cost function could change in anunpredictable way

V3 Relating Our Findings to the Existing Theoretical Models ofMenu Costs

In order to assess the magnitude of these menu cost guresin the context of the existing theoretical menu cost literatureconsider the following calculation experiments done within theframework of two theoretical menu cost models Blanchard andKiyotaki [1987] study a general equilibrium menu cost modelwith monopolistic competition and with unit elasticity of aggre-gate demand with respect to real money balances According totheir calculations menu costs of the magnitude of 008 percent ofrevenues which they consider ldquovery smallrdquo may be sufcient toprevent adjustment of prices Ball and Romer [1990] conductsimilar calculations in the framework of a model with imperfectcompetition and menu costs They nd that for plausible markupand labor elasticity parameter values menu costs needed to pre-vent price adjustment are 070 percent of revenues which as theysuggest are nonnegligible For smaller menu costs eg 004 per-cent of the revenue which Ball and Romer consider ldquotrivialrdquo im-plausibly large values of markup and labor elasticity parametersare needed to prevent price adjustment to monetary shocks

According to the gures in Table IV the reported menu costto revenues ratio for Chains AndashD averages 070 percent rangingfrom 061 percent to 076 percent These are signicantly largerthan the ldquotrivialrdquo 004 or 008 percent gures mentioned abovesuggesting that the menu cost gures we nd here are nontrivialFurther under the model and parameter values considered byBlanchard and Kiyotaki [1987] the menu cost gures we nd arehigher than the theoretical minimum needed to form a barrier toprice adjustments Under the model and parameter values con-sidered by Ball and Romer [1990] the reported menu costreve-nue ratio for all but one chain reaches or crosses the theoreticalthreshold of 070 needed to form a barrier to price adjustmentsThe existence of numerous unmeasured menu cost componentsdiscussed in subsection III5 also raises the possibility that theactual menu costs incurred by these chains are signicantlyhigher than that threshold This suggests that the menu costs wereport may be large enough to form a barrier to nominal priceadjustments when interpreted in the context of these models

An issue of interest in this literature is time-dependent ver-sus state-dependent pricing rules (see for example Caplin andLeahy [1991]) The evidence from our data set on the timing of

THE MAGNITUDE OF MENU COSTS 819

price changes suggests that the price change decisions in thesesupermarkets have a strong time-dependent price-setting ele-ment36 For example according to Table VI the prices in Chain Aare changed weekly according to the following schedule the pricechanges of general merchandise that is advertised is done Satur-day nights grocery and produce prices are changed Sundaynights the rest of the general merchandise prices are changed onMonday nights and the prices of advertised grocery items arechanged on Tuesday nights Thus as the gures in Table VI indi-cate over 96 percent of the price changes are done during Sundayand Monday nights However this does not imply that state-dependent pricing rules are unimportant Even if price changesacross product categories follow a prescheduled weekly time ta-ble the prices of which products to change is likely to be a state-dependent decision For example it could depend on changes insupply and demand conditions such as competitorsrsquo price changedecisions Indeed Levy Dutta and Bergen [1996] use retailstore-level orange juice price and cost data to demonstrate thatthe extent of price response to cost shocks that is the extent ofprice rigidity may depend on the nature of supply shocks37

We do not want to overstate the usefulness of our data fordirectly addressing the issue of monetary nonneutrality On onehand authors such as Caplin and Spulber [1987] have demon-strated that under certain conditions individual price rigiditymay not be sufcient for aggregate price rigidity but unfortu-nately our data do not speak directly to this issue38 On the otherhand authors such as Akerlof and Yellen [1985] Mankiw [1985]Parkin [1986] and Caplin and Leahy [1997] have shown that even

36 Danziger [1983] Caballero [1989] and Ball and Mankiw [1994] suggestthat time-dependent price adjustment of the type documented here can be optimalif the cost of gathering information about the state exceeds the cost of making theprice adjustment itself

37 We also considered the possibility of convexities in the cost of changingprices Our data do not suggest many convexities since the labor time spent inthe price tag change process the cost of printing and delivering price tags andin-store supervision time do not change with the size of a price change The onlymeasurable component of menu costs that could be convex is the cost of mistakesmade the larger the price change the higher the probability of a customer notic-ing the mistake and the larger the amount required to be refunded as compensa-tion Among the unmeasured components of menu cost the cost of corporatemanagerial time may increase with the size of a price change because larger pricechanges may require more serious consideration

38 Also see Balke and Wynne [1996] and Bryan and Cecchetti [1996] Sincewe do not have measures of how menu costs change over time our data also havelittle to say about time variation in menu costs or about the relationship betweenmenu costs and ination which during the period of the data collection (1991ndash1992) averaged about 3 percent annually

QUARTERLY JOURNAL OF ECONOMICS820

small menu costs can be relevant since they may be sufcient togenerate substantial aggregate nominal rigidity and thus largebusiness cycles Therefore as Blinder [1994] Kashyap [1995]and Slade [1996a] emphasize it is important to search for directevidence that such costs are indeed present at the micro level Bydirectly identifying documenting and measuring the magnitudeof menu costs at the store level we are taking an important stepin that direction

VI CONCLUSION AND FUTURE RESEARCH

Our main contribution is that we provide direct microeco-nomic evidence on the actual magnitude of menu costs for fourlarge U S retail supermarket chains The annual menu costs perstore at these chains average $105887 comprising 070 percentof revenues 352 percent of net prot margins and $052 perprice change on average

Further we provide evidence which suggests that thesemenu costs may be forming a barrier to price changes Specifi-cally we show that (1) supermarket chains not subject to itempricing law change prices two and a half times more frequentlythan the chain that is subject to the law (2) within the chain thatis subject to the item pricing law they change prices over threetimes as frequently for products that are exempt from this lawthan for the products which are subject to this law and (3) wend that these chains do not adjust prices of up to one-third ofthe products for which they face cost increases because of menucost considerations

When we relate these ndings to the existing theoreticalmodels of menu costs we conclude that the magnitude of menucosts we nd is large enough to be capable of having macroeco-nomic signicance Specically when considered in the context ofthe theoretical menu cost models of Blanchard and Kiyotaki[1987] and Ball and Romer [1990] we nd that the menu costgures we report are ldquonontrivialrdquo and their relative magnitudescross the minimum theoretical threshold needed to form a barrierto price adjustments

Despite the high relative magnitude of the marginal cost ofchanging price that we found the data still indicate frequentweekly price changes This is because of the high marginal bene-t of changing price which is due to the erce competition foundin the retail supermarket industry That marginal benets may

THE MAGNITUDE OF MENU COSTS 821

outweigh the marginal costs of changing prices in this industryhowever does not rule out the possibility that menu costs of themagnitude we nd here can create substantial nominal rigidityin other industries or markets In less competitive industries andmarkets menu costs of the type and magnitude we documenthere are likely to have a bigger impact on the frequency of priceadjustment and consequently on the degree of price rigidity

At a minimum the direct dollar measures of menu costs wereport here can be used as a starting point for future research onmeasuring their magnitude in other industries and establish-ments We anticipate that these menu costs will be similar inother markets which rely on posted prices (such as drugstoresdepartment stores etc) because the steps involved in the pricechange process are likely to be similar What may differ are thefrequency of price changes and the labor wage rates at thesestores For example since supermarket chains change thousandsof prices each week the total annual menu costs incurred bythese chains per store are likely to be high in comparison to otherretail formats such as chain drugstores or department storesThere are however a variety of industries for which the stepsinvolved in changing prices would be signicantly different fromthose reported in our study For example business-to-businesssales which often rely on a sales force will require changes in thelist price sheets changes in the instructions to the sales forcewhich may include education and discussion with the salespeoplein the company and so forth These business-to-business pricesalso often have more complex pricing schemes including quantitydiscounts bundling and individually negotiated prices As an-other example the composition of the cost of changing the news-stand prices of magazines [Cecchetti 1986] or the prices ofproducts sold through catalogs [Kashyap 1995] are different frommany of the menu cost components we discuss here Further thending that a centralization of pricing decisions makes the store-level managerial component of menu cost relatively small sug-gests that the managerial menu costs likely are highest insettings where price change decisions are decentralized Thus fu-ture empirical work should look at menu cost and its compositionin a variety of other industries markets and products with bothcentralized as well as decentralized price change decisions in or-der to see whether the magnitude of these costs can be general-ized and benchmarks can be established Further there aretechnological changes taking place in this and other industries

that promise to alter the structure of menu costs which deserveattention At the theoretical level our ndings suggest that it maybe worthwhile to explore models which incorporate the idea ofitem pricing laws as an additional component of menu costs

a HL (HighLow) and EDLP (Every Day Low Price) refer to the general pricing strategy followed by theretail chain Under the EDLP strategy the retailer rsquos prices are low for extended periods of time and there-fore it will offer fewer promotional sales or discounts Under the HL pricing strategy in contrast the retail-errsquos prices are higher and the retailer tends to offer more frequent discounts through sales and promotionsSee the text for more details

b The share of products for which prices change on an average week is the ratio of number of pricechanges per store per week to 25000 The latter is the average number of products carried per store eachweek

States These chains are similar in the variety selection andquantity of the products they carry Supermarket chains of thistype make up $310146666000 in total annual sales which is863 percent of total supermarket chain sales in 1992 [Supermar-ket Business 1993] so the chains in our sample are representativeof a major class of the retail grocery trade

According to the second row in Table I the number of weeklyprice changes in Chains AndashD ranges from 3223 to 4316 for anaverage of 3916 per store8 The variation in the number of weeklyprice changes across the chains is due in large part to their choiceof pricing strategy Chains A and B follow a highlow (HL) pricestrategy while Chains C and D follow an everyday-low-pricestrategy (EDLP) Under the EDLP strategy the retailerrsquos pricesare low for an extended period of time and therefore it will offerfewer promotional sales or discounts Under the HL pricing strat-egy in contrast the retailerrsquos prices are higher and the retailertends to offer more frequent discounts through sales and promo-tions The pricing strategy therefore will have an effect on thefrequency of price changes observed In particular we would ex-

pect EDLP stores to have less frequent price changes in compari-son to the HL stores Indeed according to Table I Chains A andB tend to have a higher number of weekly price changes (4278and 4316 respectively) than Chains C and D (3846 and 3223respectively)

Supermarkets of the size we study tend to carry around25000 different items on a regular basis9 The last row in thetable presents the share of the 25000 products for which the su-permarket chains change their prices in a period of one weekThe average share for the four chains is 1566 percent

III ABSOLUTE MEASURES OF MENU COSTS

There are four components of menu costs that we are able tomeasure in dollar terms10 These are (1) the cost of labor requiredto change the shelf price tags (2) the cost of printing and deliv-ering new price tags (3) the cost of mistakes made during theprocess of changing prices and (4) the cost of in-store supervisiontime spent on implementing price changes

III1 Costs of the Labor Required to Change Shelf Prices

Figure I displays an overview of the steps involved in chang-ing prices at Chain A There are three main components in thelabor costs incurred by the chains (a) labor cost of tag changepreparation (b) labor cost of the tag change itself and (c) laborcost of verifying whether the price changes are done correctlywhich include tag change verication in-store resolution of pricemistakes and zone and corporate resolution of price mistakes11

9 The supermarkets often have about 40000 UPC codes in their computerdatabase records but internal studies undertaken by the ESL company indicatethat the supermarkets usually carry no more than 25000 products at any giventime The extra UPC codes are for seasonal or promotional sizes and packages ofproducts and for discontinued products

10 In this paper we only report measures of the marginal cost of changingprices The costs of putting a price tag for the rst time and other costs thatwould be included in the average cost are not included in the gures we reportOnly when discussing Chain E which is the chain subject to item pricing lawsdid we face the issue of cost of pricing (at the rst time) versus the cost of changinga price Since there was no clear way of separating the two types of costs thereported cost gure ($44168 in the second paragraph of Section IV) was excludedaltogether from our calculations Also see footnote 13

11 For a detailed description of the entire price change process with ow-charts documenting the specic steps undertaken in this process and the exacttime period spent on each step see Levy Dutta Bergen and Venable [1997] Anappendix reporting computational details are contained in a working paper ver-sion of this paper which is available upon request

FIGURE IOverview of the Price Change Process

POS denotes Point of Sale and refers to the cash register or the database itis connected to or both For information on the various steps undertaken in eachstage of the price change process and the amount of the labor time spent on mosttime-consuming steps see Table II

Standard price tag changes which include the steps outlined onthe left-hand side of Figure I make up the majority of pricechanges in these chains Some price changes also require addi-tional price signs to be placed at different locations in the storesuch as on an end of aisle display or near the shelf12 These sign

12 These are usually related to the product being on promotion feature ad-vertising display or in-store sale such as ldquomanagerrsquos specialrdquo ldquotodayrsquos specialrdquoetc The steps involved in making sign changes are similar to price changes Themain differences are that (i) the time required for each of the steps in sign changes

changes add to the menu costs and they are outlined on theright-hand side of Figure I the sign change preparation actualsign changes and sign change verication boxes The bottom twoboxes in Figure I are additional menu costs related to the extrasteps taken in these stores to make sure the tag and sign changeshave been done correctly13

Table II lists each stage of the price change process the totalamount of time spent on each stage each week on average andthe number of tasks performed In addition the table identiessome of the main tasks performed in each stage as well as thefour most time-consuming tasks in each stage To compute thetotal labor time used in changing prices on a weekly basis wecombine the data collected through in-store time and motion ob-servations with information on the volume of products for whichprices are changed These weekly hours are multiplied by thewage rates (adjusted for fringe benets) of the employees used inthe price change process to get the total costs of labor required tochange prices

For the four supermarket chains in our study the total an-nual labor cost of changing the shelf price tags ranges from$40027 to $61414 per store for an average of $52084 (see therst row in Table III making up about 49 percent of the totalmenu costs on average The labor cost of changing the price signsrange from $16411 to $27955 per store for an average of$22183 (see the second row in Table III) making up almost 21percent of the menu costs on average Thus for the four super-market chains the total annual menu costs associated with thelabor required to change prices (shelf price tags and price signscombined) range from $62210 to $81703 per store for an annualaverage of $74267 This is the single largest component of themenu costs we report in this study making up about 701 percentof the total menu costs for these chains on average This shouldnot be surprising given that the most signicant portion of retail

are longer because they are in less standard locations and (ii) there are fewersign changes than standard shelf price tag changes

13 The menu cost measures we report do not include the cost of changingprices in cases where items are moved from shelf to shelf or where shelf space isreallocated by increasing the shelf space for some products at the expense of oth-ers However they do include the cost of pricing new products when they are rstintroduced While this could bias the menu cost measures upward since it reallycaptures the cost of pricing rather than the cost of changing price the size of thisbias is marginal due to the small number of new products For example accordingto ESL company executives the number of new products introduced at thesechains each week ranges from 20 to 100 approximately In comparison to the num-ber of products for which prices are changed each week (3223ndash4316) the biasis negligible

grocery operating expenses is labor costs [Hoch Dreze andPurk 1994]14

III2 Costs of Printing and Delivering New Price Tags

There are direct costs associated with printing and deliv-ering the price and sign tags The order must be recorded andprocessed at the chain sent to the printer recorded and pro-cessed at the printer printed packaged and then delivered toeach store The cost per tag is usually quite low $0017 per tagat Chain A which includes stock costs of $00118 per tag impres-sion and data center operator costs of $00037 per tag and mailroom handling costs of $00010 per tag There are however manyprice changes undertaken each week In total the costs of print-ing and delivering the price and sign tags range from $3048 to$10018 averaging $6014 per store per year (see Table III)These costs comprise less than 6 percent of the total menu costswe report

III3 Costs of Mistakes Made in the Process of Changing Prices

Despite the labor put into checking to make sure that theprice changes are done correctly there are still many price mis-takes that are not caught until customers discover them through-out the week and these mistakes impose costs on the chainClearly the costs associated with these errors must be consideredwhen deciding whether to change prices or not and therefore area relevant dimension of menu costs These mistakes can occur sooften that they were a feature of a Dateline segment on U Ssupermarket chains [NBC April 1992] and an article in MoneyMagazine [April 1993] Both the Money Magazine article andGoodstein [1994] report that on average 10 percent of the prod-ucts they examined had price mistakes A more recent study bythe Federal Trade Commission [1996] reports a total error rate ofabout 5 percent

The menu costs associated with these mistakes include lost

14 Our measure of labor cost may overstate the true costs of changing pricesif supermarkets hoard labor to save hiring and ring costs However this is notlikely to be the case for several reasons First the labor costs of changing priceswe report are based on actual measurements of the minimum amount of time andlabor required to accomplish the task rather than on the number of employeeshired to change prices at the store Second the adjustment in the amount of laboris usually done through hours worked which makes cost of hiring and ring lessrelevant And third the workers on the oor are routinely moved from task totask according to the need These tasks include stocking cleaning price changingcustomer service etc The workers employed by supermarket chains are alwaysbusy and so the opportunity cost of changing price is not zero Therefore laborhoarding is not likely to be an important factor in our measurements

QUARTERLY JOURNAL OF ECONOMICS806

cashier time to correct the errors scan guarantee refunds andinventory mistakes associated with incorrect price tags15 Lostcashier time is measured here in terms of wage payments Scanguarantee refunds are additional price reductions beyond the er-ror or additional items given away for free because of the mis-take Finally the inventory mistakes costs we report include onlythe cost of stockouts which occur when shelf price is lower thanintended

The mistake costs were available at Chains A C and D andthey range from $19135 to $20692 for an average of $20140 perstore annually (see Table III) These costs are the second largestcomponent of menu costs in our study comprising about 19 per-cent of the total

III4 Costs of In-Store Supervision Time Spent on ImplementingPrice Changes

Managers at the store level spend time overseeing imple-menting and troubleshooting the price change process OnlyChains A and B had a measure of the menu costs associated withthis in-store supervision time and both of these came from a self-reported number of hours spent on changing prices by the manag-ers at these chains The hours spent on changing prices were thesame across the chains approximately ve hours per week Thusthe menu costs for in-store supervision time came to $4241 and$6692 per store annually for Chains A and B respectively (seeTable III) These costs comprise less than 6 percent of the totalmenu costs we report in this paper However notice that thesemeasures do not include the cost of the management time spenton price change decisions made at corporate headquarters whichis discussed next

III5 Components of Menu Costs We Are Unable to Measure inDollar Terms

Our data set does not contain the exact dollar measures ofsome menu cost components One such component is the cost ofcorporate management time spent on price change decisions16 In

15 Other likely costs of price mistakes that we do not consider explicitlybecause we are unable to measure them in dollar terms are legal problems (whenthe scanner price is higher than the shelf price) loss in customer goodwill anddecreased protability (when the scanner price is lower than the shelf price)

16 It has been suggested that the cost of managerial decisions is one of themost important components of menu cost See for example Ball and Mankiw[1994] Kashyap [1995] and Meltzer [1995] Since the ESL system was not de-

THE MAGNITUDE OF MENU COSTS 807

the supermarket chains we study prices are generally set at cor-porate headquarters in a weekly meeting where the manager incharge of setting prices looks at a variety of information including(a) any manufacturer wholesale price changes promotions andother related issues (b) past sales for this product and (c) com-petitorsrsquo prices Based on this information and on discussionswith other managers the price-setting manager decides whetherto change prices and if so by how much

To estimate the magnitude of these managerial componentsof the menu costs consider the following In an average chainthere is at least one executive of merchandising who devotesmost of hisher time to pricing decisions In addition there areup to three senior managers who would deal with pricing andto whom category managers report There are also ten-to-twelvecategory managers who are responsible for setting prices on allthe products within their category An additional two-to-fourpeople spend full time handling the implementation of pricechanges across retail outlets coordinating the printing and deliv-ery of price tags and handling pricing problems in the systemAnother ve-to-seven workers gather the data on competitorsrsquoprices and analyse both the competitorsrsquo data and the storersquos ownscanner data to put it in a form useable by managers makingpricing decisions Thus in total there are about 21ndash27 peopleworking at the corporate headquarters on price change decisionsAssuming $150000 as the average annual salary of the executiveof merchandising and senior managers $100000 for categorymanagers and $50000 for the rest the chainwide managerialcost falls in the neighborhood of $23ndash$29 million a year whichseems a substantial amount However note that these pricing de-cision are made for the entire chain and therefore the costs perstore are signicantly less especially for the larger chains Forexample using $29 million as the upper bound the additionalannual menu cost per store for Chains AndashD which on averageoperate about 400 stores each averages about $7250 which ismuch lower than expected and is due to the centralization of theprice change decisions in the chains we study17

signed to save the costs of corporate headquarter managerial time spent on pricechange decisions the ESL company did not measure this component of menucosts The estimates reported in this section are based on the information receivedfrom the ESL company executives

17 A decentralization of the price change process say by allowing the store-level managers to make price change decisions can change these gures tremen-dously For example consider the following thought experiment conducted using

QUARTERLY JOURNAL OF ECONOMICS808

Our menu cost measures also do not include the cost ofchanging prices of direct store delivery (DSD) products Theseproducts are almost completely handled by manufacturers in-cluding stocking monitoring inventories and setting and chang-ing prices18 We have data on the weekly frequency of pricechanges of DSD products in Chain E In an average week thereare 174 price changes of DSD products which is about 10 percentof the supermarketrsquos total weekly price changes Using the costof changing the price of a regular product $133 (see Section IVfor details) the annual cost of changing prices of the DSD prod-ucts in this chain roughly equals $1203419 Our menu cost mea-sures do not include these gures since we do not have similardata for the other chains20

III6 Total Menu Costs

The total annual menu costs reported for each chain perstore are listed in the last row of Table III As the table indicatesthe menu costs range from $91416 to $114188 for an average of$105887 per store per year21 Note that these menu cost mea-

the average annual per store gures for Chains AndashD Suppose that the supermar-ket chains decentralize the price change process by hiring for each store only one-quarter of the price change managing team while at the same time they com-pletely eliminate the corporate level team The resulting annual menu cost perstore would be $830887 ( 5 $105887 1 $725000) which would dwarf any of themeasurable menu cost gures we report in this study Even if the average storeonly hired just the merchandising manager at the annual cost of $150000 itwould still incur annual managerial cost of about $255887 ( 5 $105887 1$150000) In other words such a trivial decentralization would double the store-level menu costs This would indeed make the cost of price change decisions themost important component of menu cost

18 DSD products usually are high-volume fast-moving or perishable prod-ucts such as milk soda eggs bread dairy snacks etc In the chains we studyabout 10ndash20 percent of the products are of a DSD type but that share may reachas much as 40 percent of the products carried [Direct Store Delivery Work Groupet al 1995]

19 The process of changing prices of DSD and of regular products is similarBut with DSD products there are additional costs of the time spent on driving tothe store parking and setting up the price change process at each store

20 Our measures of menu cost also do not incorporate the cost of informingconsumers about price changes which can take a variety of forms such as newspa-per ads and inserts TV and radio ads in-store promotion signs etc Finally wehave no data on lost customer goodwill and damaged reputation caused by dis-crepancies between price tag and cash register [Okun 1981 Carlton and Perloff1994 Haddock and McChesney 1994]

21 The variation in the menu costs across the chains is mostly due to wagerate and labor-efciency variations Also note that since the supermarket chainsin our sample are similar in the size of their stores carry similar sets of productsand follow similar processes of price change and price change decisions it is rea-sonable to believe that the chains incur similar types of costs Therefore as notedunderneath Table III these menu cost measures are computed by replacing theunreported gures by the averages of the available values from the other chains

THE MAGNITUDE OF MENU COSTS 809

sures include only the components we could accurately measurein dollar terms which are discussed in subsections III1ndashIII4

IV ITEM PRICING LAWS AND MENU COSTS

In this section we provide evidence on the menu costs for anadditional chain (Chain E) which unlike the other four chainsoperates in a state with an item pricing law The most importantaspect of item pricing laws is that they require a price tag on eachindividual item sold not just on the shelf which is what the otherfour chains in our sample do For example the item pricing lawin Connecticut requires that the grocers ldquoshall mark or cause tobe marked each consumer commodity which bears a UniversalProduct Code with its retail pricerdquo 22 From a menu cost perspec-tive the requirement of posting prices on every item (in additionto the shelf price tag) introduces additional costs in the processof changing prices

Although most of the steps involved in changing prices arethe same for both types of chains stores that are subject to itempricing laws have to undertake additional steps to obey this law23

The labor cost component of menu costs in Chain E totals $75127a year of which $49710 is the cost of the labor time spent onchanging the prices of individual items $3234 is the cost of thelabor time spent on shelf tag replacements and $22183 is thecost of the labor time spent on sign changes (see Table III)24 Anadditional $44168 is spent annually putting prices on new itemsas they are brought to the shelves Although we do not includethis last gure in our menu cost measures because we do not haveinformation on how much of it is due to price change activity andhow much due to just pricingmdashthese costs are clearly a directconsequence of the item pricing law The printing and deliverycost of price tags and price signs are $7644 and the mistake

22 Public Act No 75ndash391 An Act Concerning Pricing of Consumer Merchan-dise [Public Acts of the State of Connecticut 1975 Vol 1 p 390]

23 These steps which are in addition to the regular steps undertaken toreplace price tags on the shelves include (1) obtaining item price tags (2) settingup workstations (3) locating the product (4) removing an item from the shelf (5)removing old price tag (6) setting marking gun (7) applying new price tag and(8) returning the item back to the shelf

24 Since we do not have a measure of the cost of labor time spent on signchanges and the cost of in-store managerial supervision time for this chain weuse the average of the chains that report them (A and D) Note also that thehourly wage rate of $907 paid by Chain E is lower than the hourly wage of about$1400ndash$2000 paid by Chains AndashD

QUARTERLY JOURNAL OF ECONOMICS810

25 Further note that the chains with smaller menu costs are likely tochange their prices more frequently which suggests that the gures of the totalannual menu costs understate the differences between Chain E and the otherchains Indeed despite the large difference in the menu cost per price change thetotal annual menu costs per store for Chain E ($109036) are more comparable tothose of Chains AndashD ($105887)

26 In calculations that follow we use industry averages because (1) thechains did not share this proprietary information with us and (2) we were re-quired to keep the identity of these chains condential as some of these numbersare detailed enough to enable some readers to identify the chains under study

costs are $20799 These gures along with the amount of $5466for the cost of in-store managerial supervision time yield totalannual menu costs of $109036 per store

Although the magnitude of the total annual menu costs seemsimilar to the other four chains note that the average weeklyfrequency of price changes in Chain E is only 1578 which is only403 ( 5 15783916) percent of the price changes made by theother four chains Thus the average menu cost per price changefor Chain E is $133 (see Table IV last row) In contrast the corre-sponding gures for Chains AndashD average $052 Hence the menucosts per price change incurred by the supermarket chain facingitem pricing laws are more than two and a half times the amountincurred by chains that are not subject to this law25 Overallthese ndings suggest that legal restrictions of the type of itempricing laws can have a signicant impact on the menu costs in-curred by sellers

V SIGNIFICANCE OF THE MENU COSTS

The next natural question to ask is how important are thesecosts To address this question we (1) provide several relativemeasures of the menu costs (2) discuss the effect of the menucosts on supermarketsrsquo price change activity and (3) discuss mac-roeconomic implications by relating our ndings to the existingtheoretical models of menu costs In each case we provide addi-tional evidence to help assess the importance of these menu costs

V1 Relative Measures of the Menu Costs

In order to assess the relative magnitude of the menu costsreported in Section IV we now present the menu cost gures rela-tive to the average store-level revenues and net prot margins26

In addition we present the menu cost gures per price changeThe annual average revenues of a large U S supermarket

chain of the type and size included in our sample is $15052716

per store27 According to the second row of Table IV the ratio ofmenu costs to revenues for Chains AndashD ranges between 061ndash076percent averaging 070 percent28 We relate the size of thesegures to the existing theoretical menu cost models in sub-section V3

Net prot margin which measures the revenues minus allcosts is approximately 1ndash3 percent of revenues for these chains[Montgomery 1994] so we use 2 percent as a working averageThe reason for the low prot rate in this industry is the intensecompetition [Calatone et al 1989] especially at the regional level[Chevalier 1995] which has been increasing since the early 1990s[Progressive Grocer November 1992 p 50] It follows that theaverage store protability for these chains equals $301054 peryear Therefore the ratio of total menu cost to net margin forChains AndashD ranges between 304ndash379 percent for an average of352 percent Thus the menu costs we report in this study repre-sent a signicant share of supermarketsrsquo prots

Another way to look at the menu cost gures we report is toexpress them relative to the frequency of price changes In thelast row of Table IV we present the menu cost gures per pricechange for each chain As the table indicates the cost of changinga price in Chains AndashD ranges between $046ndash$068 for an averageof $052 For Chain E the gure is substantially larger $133 perprice change29 These gures are lower than the estimated cost of

27 This is the average of two different estimates $12945432 and$17160000 The source of the rst gure is internal record of a supermarketchain of the type and size studied here The second gure comes from Supermar-ket Business [1993 p 52]

28 We also measured the menu costs in terms of controllable operating ex-penses (which are the portion of costs that the retailer has direct control over andtherefore are often the costs that the retailer is most focused on managing) andgross margins (which measure the supermarket revenues minus direct cost of theproducts it sells) We nd that the menu costs comprise 313 percent of controlla-ble operating expenses and 281 percent of gross margins at these chains on aver-age Finally if we measure the menu costs relative to the number of productscarried per store (about 25000) then we nd that the menu costs per productaverage $423 for Chains AndashD See Table IV and its footnotes for details

29 We can also try to express the menu cost gures relative to the numberof individual items sold by these chains each year (Note the difference betweennumber of products carried and number of items sold As an example a TartarControl Crest 8oz would be considered a product carried and 300 units of themsold per year would be considered number of items sold) Using $170 as the aver-age price of all the products sold we nd that the menu cost per item sold for thefour chains is in the range of $00103ndash$00129 for an average of $00119 (see TableIV second to last row) To see the relative magnitude of these gures note thataccording to Berkowitz Kerin and Rudelius [1986 p 319] the goal of the super-market chains of the type we study ldquo is to make 1 penny of prot on each dollarof salesrdquo Thus menu cost per item sold when adjusted for the average price

THE MAGNITUDE OF MENU COSTS 813

$200ndash$300 per price change reported by Slade [1996a] Thereare several possible reasons for this (1) our menu cost gures arebased on actual measurements of the resources that go into theprice change process whereas she estimates menu costs econo-metrically as model coefcients using a mix of store-level priceand aggregate cost data (2) we cover 25000 products that thesupermarkets carry rather than a single product category (3) ourmenu cost gures do not include all components of menu costsand (4) there could be differences in wage rates that may be im-portant given the signicance of the labor cost component inmenu costs

V2 The Effect of Menu Costs on the Price Change Activity of theSupermarkets

In this section we present evidence which suggests that thesemenu costs may be forming a barrier to price change activity Tobegin with consider the effect of the item pricing law on the pricechange activity of Chain E The data on the weekly frequency ofprice changes in each chain are displayed in the last two rows ofTable I According to these gures the average weekly frequencyof price changes in Chain E is only 1578 Thus on average ChainE changes the prices of only 631 percent of its products eachweek In contrast the average weekly frequency of price changesat Chains AndashD ranges from 3223 to 4316 for the four-chain aver-age of 3916 price changes weekly So Chains AndashD change priceson 1289 to 1726 percent of their products each week yielding afour-chain average of 1566 percent Thus Chain E which facesthe item pricing law changes prices only about one-third timesas frequently as do Chains AndashD30

Moreover within Chain E there are 400 products that areexempt from the item pricing law and thereby face lower menucosts We nd that there are an average of 83 weekly pricechanges for these products yielding 21 percent of these productschanging prices So within Chain E they change prices over threetimes as frequently for products with lower menu costs than for

roughly equals one-half of their target net prot per item which seemssubstantial

30 However note that our comparison of the two types of chains may not becompletely ceteris paribus because these stores are located in different states andtherefore there may be other chain-specic factors (in addition to item pricinglaws) that distinguish these stores We do not have any specic information onthese differences We do know however that the stores in these chains are similarin size and carry similar sets of products

QUARTERLY JOURNAL OF ECONOMICS814

the products with higher menu costs Note that this nding is onthe price change activity within the same chain offering almost anatural experiment on the impact of menu costs on the chainrsquospricing behavior Hence we provide evidence both across chainsas well as across products within a chain that as the costs ofchanging price go up the frequency of price changes goes downThus the menu costs we nd are signicant enough to affect thechainrsquos price change practice

We also have additional evidence from Chains A B and Dabout these menu costs being a barrier to certain price changesand it is summarized in Table V According to the Price Manage-ment Department of Chain A the chain experiences cost in-creases on 860 products in an average week to which it wouldlike to react with a price increase31 However on average 22 per-cent of these price increases are not implemented immediatelybecause the cost of changing prices for these products is too highto make it economically worthwhile Figures of the same magni-tude were reported by other chains For example Chain D experi-ences cost increases for 961 products in an average week Out ofthese the chain adjusts prices of only 633 products The re-maining 34 percent of the prices are left unadjusted because ofthe menu costs Similarly Chain B nds it economically ineffi-cient to adjust prices of 508 ie 30 percent of its products eachweek because of menu costs This provides additional evidencethat the menu costs incurred by these chains are preventing priceadjustments to some costs changes leading to price rigidities ofthe products involved32 Note that although we do not have simi-lar data for Chain E we would expect signicantly lower num-bers on this measure at that chain These gures also suggest anupper bound on the benet of complete price exibility under thecurrent pricing practice of weekly price adjustments Howeverif new technologies (eg ESL systems) and new pricing prac-tices (eg a decentralization of the price change decisions) are

31 Our data contain information only on the frequency of cost increasesAlthough it is more than likely that the supermarkets are experiencing cost de-creases as well our data set contained no information on such decreases

32 Menu costs may even be playing a role in the observed movement towardpricing strategies that rely on fewer price changes such as EDLP [Blattberg andNeslin 1989 Lattin and Ortmeyer 1991 Marketing News April 13 1992 p 8]According to Progressive Grocer [November 1992 p 50] ldquoA growing number ofoperators say they have switched from high-low pricing [to EDLP] They cite theinefciencies of making frequent price changes rdquo Similarly Hoch Dreze andPurk [1994 p 16] state that EDLP lowers operating costs by lowering ldquo in-store labor costs because of less frequent changeovers in special displaysrdquo

adopted allowing a fundamental change in the way the pricingmechanism is currently set the managers could consider morefrequent price change activity (eg multiple times each week) asmenu costs go down

In this paper we measure the menu costs at the chainsrsquo cur-rent level of price change activity It may be worthwhile to specu-late on the shape of the cost function relating menu costs to thefrequency of price changes by assessing how these costs wouldchange if the price change activity were to increase or to decreaseIt seems likely that many of the costs we report in this paper will(approximately) change linearly with additional price changeswithin the current range of price changes the chains are under-taking (plus or minus perhaps a thousand per week) For ex-ample the labor costs associated with changing a shelf price tagcosts of verifying price changes and the costs of mistakes oc-curring during this process all increase linearly with the fre-quency of price changes This is because most of the time-consuming steps involved in the price change process must berepeated each time an additional shelf price tag is changed (seeTable II) Further we were unable to nd many tasks that gener-ated signicant returns to scale It is unclear what cost savingsare available if the price change activity drops substantially be-

low the levels it is at now Clearly if price changes were nearzero or done less frequently than weekly (say monthly) therecould be major differences in these costs

What is less clear is how these costs would change at moreextreme levels of price change activity With less frequent pricechanges the menu costs could probably be reduced signicantlyalthough the cost of deciding what prices to set initially and thecost of putting the initial shelf price tags would still remain as alower bound of the menu cost However for achieving more priceexibility by changing prices more frequently (ie multiple timeseach week) substantial changes must be undertaken At presentthe supermarket chains are set up to make the majority of theirprice changes on a weekly basis with the appropriate systems inplace to make this process most efcient For example in orderto save costs and to have higher quality price tags (eg withcolor more details greater clarity glossy etc) the chains oftensend new price tag requests to a printing shop which takes threedays to print and deliver the labels to each store Then giventhe large number of price changes taking place and the goals ofminimizing customer disruptions and labor costs (such as over-time pay) and coordinating with advertised price promotions theprices are changed in the store over a two-to-three-day period (seeTable VI) The combination of these schedule and built-in lags isacceptable under the current practice of changing prices weeklybut would have to be adjusted dramatically to allow for signifi-cantly more frequent price changes on a regular basis

Perhaps even more imposing are the costs of changing themanagerial costs associated with the current weekly system ofprice changes The process of pricing at this organizational levelis not a self-contained activity taking place in isolation from otheroperations of the supermarket management Rather it is a partof a larger system of business decisions and operations The cur-rent process of operations (such as data collection and theiranalysis management meetings coordination of the decisionsacross functional areas etc) is set up to function on a weeklybasis33 Further these management accounting and logisticssystems are currently built around a tremendous amount of in-

33 For example the data are analyzed and presented to managers on Mon-day and Tuesday with meetings set for Thursday and Friday to make pricingdecisions for the next week in coordination with all other business functions ofthe chain

35 If the supermarket chains indeed restructure the entire price change pro-cess and begin to change prices much more frequently (say two-to-three times aweek) on a regular basis then the shape of this cost function could change in anunpredictable way

V3 Relating Our Findings to the Existing Theoretical Models ofMenu Costs

In order to assess the magnitude of these menu cost guresin the context of the existing theoretical menu cost literatureconsider the following calculation experiments done within theframework of two theoretical menu cost models Blanchard andKiyotaki [1987] study a general equilibrium menu cost modelwith monopolistic competition and with unit elasticity of aggre-gate demand with respect to real money balances According totheir calculations menu costs of the magnitude of 008 percent ofrevenues which they consider ldquovery smallrdquo may be sufcient toprevent adjustment of prices Ball and Romer [1990] conductsimilar calculations in the framework of a model with imperfectcompetition and menu costs They nd that for plausible markupand labor elasticity parameter values menu costs needed to pre-vent price adjustment are 070 percent of revenues which as theysuggest are nonnegligible For smaller menu costs eg 004 per-cent of the revenue which Ball and Romer consider ldquotrivialrdquo im-plausibly large values of markup and labor elasticity parametersare needed to prevent price adjustment to monetary shocks

According to the gures in Table IV the reported menu costto revenues ratio for Chains AndashD averages 070 percent rangingfrom 061 percent to 076 percent These are signicantly largerthan the ldquotrivialrdquo 004 or 008 percent gures mentioned abovesuggesting that the menu cost gures we nd here are nontrivialFurther under the model and parameter values considered byBlanchard and Kiyotaki [1987] the menu cost gures we nd arehigher than the theoretical minimum needed to form a barrier toprice adjustments Under the model and parameter values con-sidered by Ball and Romer [1990] the reported menu costreve-nue ratio for all but one chain reaches or crosses the theoreticalthreshold of 070 needed to form a barrier to price adjustmentsThe existence of numerous unmeasured menu cost componentsdiscussed in subsection III5 also raises the possibility that theactual menu costs incurred by these chains are signicantlyhigher than that threshold This suggests that the menu costs wereport may be large enough to form a barrier to nominal priceadjustments when interpreted in the context of these models

An issue of interest in this literature is time-dependent ver-sus state-dependent pricing rules (see for example Caplin andLeahy [1991]) The evidence from our data set on the timing of

THE MAGNITUDE OF MENU COSTS 819

price changes suggests that the price change decisions in thesesupermarkets have a strong time-dependent price-setting ele-ment36 For example according to Table VI the prices in Chain Aare changed weekly according to the following schedule the pricechanges of general merchandise that is advertised is done Satur-day nights grocery and produce prices are changed Sundaynights the rest of the general merchandise prices are changed onMonday nights and the prices of advertised grocery items arechanged on Tuesday nights Thus as the gures in Table VI indi-cate over 96 percent of the price changes are done during Sundayand Monday nights However this does not imply that state-dependent pricing rules are unimportant Even if price changesacross product categories follow a prescheduled weekly time ta-ble the prices of which products to change is likely to be a state-dependent decision For example it could depend on changes insupply and demand conditions such as competitorsrsquo price changedecisions Indeed Levy Dutta and Bergen [1996] use retailstore-level orange juice price and cost data to demonstrate thatthe extent of price response to cost shocks that is the extent ofprice rigidity may depend on the nature of supply shocks37

We do not want to overstate the usefulness of our data fordirectly addressing the issue of monetary nonneutrality On onehand authors such as Caplin and Spulber [1987] have demon-strated that under certain conditions individual price rigiditymay not be sufcient for aggregate price rigidity but unfortu-nately our data do not speak directly to this issue38 On the otherhand authors such as Akerlof and Yellen [1985] Mankiw [1985]Parkin [1986] and Caplin and Leahy [1997] have shown that even

36 Danziger [1983] Caballero [1989] and Ball and Mankiw [1994] suggestthat time-dependent price adjustment of the type documented here can be optimalif the cost of gathering information about the state exceeds the cost of making theprice adjustment itself

37 We also considered the possibility of convexities in the cost of changingprices Our data do not suggest many convexities since the labor time spent inthe price tag change process the cost of printing and delivering price tags andin-store supervision time do not change with the size of a price change The onlymeasurable component of menu costs that could be convex is the cost of mistakesmade the larger the price change the higher the probability of a customer notic-ing the mistake and the larger the amount required to be refunded as compensa-tion Among the unmeasured components of menu cost the cost of corporatemanagerial time may increase with the size of a price change because larger pricechanges may require more serious consideration

38 Also see Balke and Wynne [1996] and Bryan and Cecchetti [1996] Sincewe do not have measures of how menu costs change over time our data also havelittle to say about time variation in menu costs or about the relationship betweenmenu costs and ination which during the period of the data collection (1991ndash1992) averaged about 3 percent annually

QUARTERLY JOURNAL OF ECONOMICS820

small menu costs can be relevant since they may be sufcient togenerate substantial aggregate nominal rigidity and thus largebusiness cycles Therefore as Blinder [1994] Kashyap [1995]and Slade [1996a] emphasize it is important to search for directevidence that such costs are indeed present at the micro level Bydirectly identifying documenting and measuring the magnitudeof menu costs at the store level we are taking an important stepin that direction

VI CONCLUSION AND FUTURE RESEARCH

Our main contribution is that we provide direct microeco-nomic evidence on the actual magnitude of menu costs for fourlarge U S retail supermarket chains The annual menu costs perstore at these chains average $105887 comprising 070 percentof revenues 352 percent of net prot margins and $052 perprice change on average

Further we provide evidence which suggests that thesemenu costs may be forming a barrier to price changes Specifi-cally we show that (1) supermarket chains not subject to itempricing law change prices two and a half times more frequentlythan the chain that is subject to the law (2) within the chain thatis subject to the item pricing law they change prices over threetimes as frequently for products that are exempt from this lawthan for the products which are subject to this law and (3) wend that these chains do not adjust prices of up to one-third ofthe products for which they face cost increases because of menucost considerations

When we relate these ndings to the existing theoreticalmodels of menu costs we conclude that the magnitude of menucosts we nd is large enough to be capable of having macroeco-nomic signicance Specically when considered in the context ofthe theoretical menu cost models of Blanchard and Kiyotaki[1987] and Ball and Romer [1990] we nd that the menu costgures we report are ldquonontrivialrdquo and their relative magnitudescross the minimum theoretical threshold needed to form a barrierto price adjustments

Despite the high relative magnitude of the marginal cost ofchanging price that we found the data still indicate frequentweekly price changes This is because of the high marginal bene-t of changing price which is due to the erce competition foundin the retail supermarket industry That marginal benets may

THE MAGNITUDE OF MENU COSTS 821

outweigh the marginal costs of changing prices in this industryhowever does not rule out the possibility that menu costs of themagnitude we nd here can create substantial nominal rigidityin other industries or markets In less competitive industries andmarkets menu costs of the type and magnitude we documenthere are likely to have a bigger impact on the frequency of priceadjustment and consequently on the degree of price rigidity

At a minimum the direct dollar measures of menu costs wereport here can be used as a starting point for future research onmeasuring their magnitude in other industries and establish-ments We anticipate that these menu costs will be similar inother markets which rely on posted prices (such as drugstoresdepartment stores etc) because the steps involved in the pricechange process are likely to be similar What may differ are thefrequency of price changes and the labor wage rates at thesestores For example since supermarket chains change thousandsof prices each week the total annual menu costs incurred bythese chains per store are likely to be high in comparison to otherretail formats such as chain drugstores or department storesThere are however a variety of industries for which the stepsinvolved in changing prices would be signicantly different fromthose reported in our study For example business-to-businesssales which often rely on a sales force will require changes in thelist price sheets changes in the instructions to the sales forcewhich may include education and discussion with the salespeoplein the company and so forth These business-to-business pricesalso often have more complex pricing schemes including quantitydiscounts bundling and individually negotiated prices As an-other example the composition of the cost of changing the news-stand prices of magazines [Cecchetti 1986] or the prices ofproducts sold through catalogs [Kashyap 1995] are different frommany of the menu cost components we discuss here Further thending that a centralization of pricing decisions makes the store-level managerial component of menu cost relatively small sug-gests that the managerial menu costs likely are highest insettings where price change decisions are decentralized Thus fu-ture empirical work should look at menu cost and its compositionin a variety of other industries markets and products with bothcentralized as well as decentralized price change decisions in or-der to see whether the magnitude of these costs can be general-ized and benchmarks can be established Further there aretechnological changes taking place in this and other industries

that promise to alter the structure of menu costs which deserveattention At the theoretical level our ndings suggest that it maybe worthwhile to explore models which incorporate the idea ofitem pricing laws as an additional component of menu costs

THE MAGNITUDE OF MENU COSTS 825

pect EDLP stores to have less frequent price changes in compari-son to the HL stores Indeed according to Table I Chains A andB tend to have a higher number of weekly price changes (4278and 4316 respectively) than Chains C and D (3846 and 3223respectively)

Supermarkets of the size we study tend to carry around25000 different items on a regular basis9 The last row in thetable presents the share of the 25000 products for which the su-permarket chains change their prices in a period of one weekThe average share for the four chains is 1566 percent

III ABSOLUTE MEASURES OF MENU COSTS

There are four components of menu costs that we are able tomeasure in dollar terms10 These are (1) the cost of labor requiredto change the shelf price tags (2) the cost of printing and deliv-ering new price tags (3) the cost of mistakes made during theprocess of changing prices and (4) the cost of in-store supervisiontime spent on implementing price changes

III1 Costs of the Labor Required to Change Shelf Prices

Figure I displays an overview of the steps involved in chang-ing prices at Chain A There are three main components in thelabor costs incurred by the chains (a) labor cost of tag changepreparation (b) labor cost of the tag change itself and (c) laborcost of verifying whether the price changes are done correctlywhich include tag change verication in-store resolution of pricemistakes and zone and corporate resolution of price mistakes11

9 The supermarkets often have about 40000 UPC codes in their computerdatabase records but internal studies undertaken by the ESL company indicatethat the supermarkets usually carry no more than 25000 products at any giventime The extra UPC codes are for seasonal or promotional sizes and packages ofproducts and for discontinued products

10 In this paper we only report measures of the marginal cost of changingprices The costs of putting a price tag for the rst time and other costs thatwould be included in the average cost are not included in the gures we reportOnly when discussing Chain E which is the chain subject to item pricing lawsdid we face the issue of cost of pricing (at the rst time) versus the cost of changinga price Since there was no clear way of separating the two types of costs thereported cost gure ($44168 in the second paragraph of Section IV) was excludedaltogether from our calculations Also see footnote 13

11 For a detailed description of the entire price change process with ow-charts documenting the specic steps undertaken in this process and the exacttime period spent on each step see Levy Dutta Bergen and Venable [1997] Anappendix reporting computational details are contained in a working paper ver-sion of this paper which is available upon request

FIGURE IOverview of the Price Change Process

POS denotes Point of Sale and refers to the cash register or the database itis connected to or both For information on the various steps undertaken in eachstage of the price change process and the amount of the labor time spent on mosttime-consuming steps see Table II

Standard price tag changes which include the steps outlined onthe left-hand side of Figure I make up the majority of pricechanges in these chains Some price changes also require addi-tional price signs to be placed at different locations in the storesuch as on an end of aisle display or near the shelf12 These sign

12 These are usually related to the product being on promotion feature ad-vertising display or in-store sale such as ldquomanagerrsquos specialrdquo ldquotodayrsquos specialrdquoetc The steps involved in making sign changes are similar to price changes Themain differences are that (i) the time required for each of the steps in sign changes

THE MAGNITUDE OF MENU COSTS 799

changes add to the menu costs and they are outlined on theright-hand side of Figure I the sign change preparation actualsign changes and sign change verication boxes The bottom twoboxes in Figure I are additional menu costs related to the extrasteps taken in these stores to make sure the tag and sign changeshave been done correctly13

Table II lists each stage of the price change process the totalamount of time spent on each stage each week on average andthe number of tasks performed In addition the table identiessome of the main tasks performed in each stage as well as thefour most time-consuming tasks in each stage To compute thetotal labor time used in changing prices on a weekly basis wecombine the data collected through in-store time and motion ob-servations with information on the volume of products for whichprices are changed These weekly hours are multiplied by thewage rates (adjusted for fringe benets) of the employees used inthe price change process to get the total costs of labor required tochange prices

For the four supermarket chains in our study the total an-nual labor cost of changing the shelf price tags ranges from$40027 to $61414 per store for an average of $52084 (see therst row in Table III making up about 49 percent of the totalmenu costs on average The labor cost of changing the price signsrange from $16411 to $27955 per store for an average of$22183 (see the second row in Table III) making up almost 21percent of the menu costs on average Thus for the four super-market chains the total annual menu costs associated with thelabor required to change prices (shelf price tags and price signscombined) range from $62210 to $81703 per store for an annualaverage of $74267 This is the single largest component of themenu costs we report in this study making up about 701 percentof the total menu costs for these chains on average This shouldnot be surprising given that the most signicant portion of retail

are longer because they are in less standard locations and (ii) there are fewersign changes than standard shelf price tag changes

13 The menu cost measures we report do not include the cost of changingprices in cases where items are moved from shelf to shelf or where shelf space isreallocated by increasing the shelf space for some products at the expense of oth-ers However they do include the cost of pricing new products when they are rstintroduced While this could bias the menu cost measures upward since it reallycaptures the cost of pricing rather than the cost of changing price the size of thisbias is marginal due to the small number of new products For example accordingto ESL company executives the number of new products introduced at thesechains each week ranges from 20 to 100 approximately In comparison to the num-ber of products for which prices are changed each week (3223ndash4316) the biasis negligible

grocery operating expenses is labor costs [Hoch Dreze andPurk 1994]14

III2 Costs of Printing and Delivering New Price Tags

There are direct costs associated with printing and deliv-ering the price and sign tags The order must be recorded andprocessed at the chain sent to the printer recorded and pro-cessed at the printer printed packaged and then delivered toeach store The cost per tag is usually quite low $0017 per tagat Chain A which includes stock costs of $00118 per tag impres-sion and data center operator costs of $00037 per tag and mailroom handling costs of $00010 per tag There are however manyprice changes undertaken each week In total the costs of print-ing and delivering the price and sign tags range from $3048 to$10018 averaging $6014 per store per year (see Table III)These costs comprise less than 6 percent of the total menu costswe report

III3 Costs of Mistakes Made in the Process of Changing Prices

Despite the labor put into checking to make sure that theprice changes are done correctly there are still many price mis-takes that are not caught until customers discover them through-out the week and these mistakes impose costs on the chainClearly the costs associated with these errors must be consideredwhen deciding whether to change prices or not and therefore area relevant dimension of menu costs These mistakes can occur sooften that they were a feature of a Dateline segment on U Ssupermarket chains [NBC April 1992] and an article in MoneyMagazine [April 1993] Both the Money Magazine article andGoodstein [1994] report that on average 10 percent of the prod-ucts they examined had price mistakes A more recent study bythe Federal Trade Commission [1996] reports a total error rate ofabout 5 percent

The menu costs associated with these mistakes include lost

14 Our measure of labor cost may overstate the true costs of changing pricesif supermarkets hoard labor to save hiring and ring costs However this is notlikely to be the case for several reasons First the labor costs of changing priceswe report are based on actual measurements of the minimum amount of time andlabor required to accomplish the task rather than on the number of employeeshired to change prices at the store Second the adjustment in the amount of laboris usually done through hours worked which makes cost of hiring and ring lessrelevant And third the workers on the oor are routinely moved from task totask according to the need These tasks include stocking cleaning price changingcustomer service etc The workers employed by supermarket chains are alwaysbusy and so the opportunity cost of changing price is not zero Therefore laborhoarding is not likely to be an important factor in our measurements

cashier time to correct the errors scan guarantee refunds andinventory mistakes associated with incorrect price tags15 Lostcashier time is measured here in terms of wage payments Scanguarantee refunds are additional price reductions beyond the er-ror or additional items given away for free because of the mis-take Finally the inventory mistakes costs we report include onlythe cost of stockouts which occur when shelf price is lower thanintended

The mistake costs were available at Chains A C and D andthey range from $19135 to $20692 for an average of $20140 perstore annually (see Table III) These costs are the second largestcomponent of menu costs in our study comprising about 19 per-cent of the total

III4 Costs of In-Store Supervision Time Spent on ImplementingPrice Changes

Managers at the store level spend time overseeing imple-menting and troubleshooting the price change process OnlyChains A and B had a measure of the menu costs associated withthis in-store supervision time and both of these came from a self-reported number of hours spent on changing prices by the manag-ers at these chains The hours spent on changing prices were thesame across the chains approximately ve hours per week Thusthe menu costs for in-store supervision time came to $4241 and$6692 per store annually for Chains A and B respectively (seeTable III) These costs comprise less than 6 percent of the totalmenu costs we report in this paper However notice that thesemeasures do not include the cost of the management time spenton price change decisions made at corporate headquarters whichis discussed next

III5 Components of Menu Costs We Are Unable to Measure inDollar Terms

Our data set does not contain the exact dollar measures ofsome menu cost components One such component is the cost ofcorporate management time spent on price change decisions16 In

15 Other likely costs of price mistakes that we do not consider explicitlybecause we are unable to measure them in dollar terms are legal problems (whenthe scanner price is higher than the shelf price) loss in customer goodwill anddecreased protability (when the scanner price is lower than the shelf price)

16 It has been suggested that the cost of managerial decisions is one of themost important components of menu cost See for example Ball and Mankiw[1994] Kashyap [1995] and Meltzer [1995] Since the ESL system was not de-

THE MAGNITUDE OF MENU COSTS 807

the supermarket chains we study prices are generally set at cor-porate headquarters in a weekly meeting where the manager incharge of setting prices looks at a variety of information including(a) any manufacturer wholesale price changes promotions andother related issues (b) past sales for this product and (c) com-petitorsrsquo prices Based on this information and on discussionswith other managers the price-setting manager decides whetherto change prices and if so by how much

To estimate the magnitude of these managerial componentsof the menu costs consider the following In an average chainthere is at least one executive of merchandising who devotesmost of hisher time to pricing decisions In addition there areup to three senior managers who would deal with pricing andto whom category managers report There are also ten-to-twelvecategory managers who are responsible for setting prices on allthe products within their category An additional two-to-fourpeople spend full time handling the implementation of pricechanges across retail outlets coordinating the printing and deliv-ery of price tags and handling pricing problems in the systemAnother ve-to-seven workers gather the data on competitorsrsquoprices and analyse both the competitorsrsquo data and the storersquos ownscanner data to put it in a form useable by managers makingpricing decisions Thus in total there are about 21ndash27 peopleworking at the corporate headquarters on price change decisionsAssuming $150000 as the average annual salary of the executiveof merchandising and senior managers $100000 for categorymanagers and $50000 for the rest the chainwide managerialcost falls in the neighborhood of $23ndash$29 million a year whichseems a substantial amount However note that these pricing de-cision are made for the entire chain and therefore the costs perstore are signicantly less especially for the larger chains Forexample using $29 million as the upper bound the additionalannual menu cost per store for Chains AndashD which on averageoperate about 400 stores each averages about $7250 which ismuch lower than expected and is due to the centralization of theprice change decisions in the chains we study17

signed to save the costs of corporate headquarter managerial time spent on pricechange decisions the ESL company did not measure this component of menucosts The estimates reported in this section are based on the information receivedfrom the ESL company executives

17 A decentralization of the price change process say by allowing the store-level managers to make price change decisions can change these gures tremen-dously For example consider the following thought experiment conducted using

QUARTERLY JOURNAL OF ECONOMICS808

Our menu cost measures also do not include the cost ofchanging prices of direct store delivery (DSD) products Theseproducts are almost completely handled by manufacturers in-cluding stocking monitoring inventories and setting and chang-ing prices18 We have data on the weekly frequency of pricechanges of DSD products in Chain E In an average week thereare 174 price changes of DSD products which is about 10 percentof the supermarketrsquos total weekly price changes Using the costof changing the price of a regular product $133 (see Section IVfor details) the annual cost of changing prices of the DSD prod-ucts in this chain roughly equals $1203419 Our menu cost mea-sures do not include these gures since we do not have similardata for the other chains20

III6 Total Menu Costs

The total annual menu costs reported for each chain perstore are listed in the last row of Table III As the table indicatesthe menu costs range from $91416 to $114188 for an average of$105887 per store per year21 Note that these menu cost mea-

the average annual per store gures for Chains AndashD Suppose that the supermar-ket chains decentralize the price change process by hiring for each store only one-quarter of the price change managing team while at the same time they com-pletely eliminate the corporate level team The resulting annual menu cost perstore would be $830887 ( 5 $105887 1 $725000) which would dwarf any of themeasurable menu cost gures we report in this study Even if the average storeonly hired just the merchandising manager at the annual cost of $150000 itwould still incur annual managerial cost of about $255887 ( 5 $105887 1$150000) In other words such a trivial decentralization would double the store-level menu costs This would indeed make the cost of price change decisions themost important component of menu cost

18 DSD products usually are high-volume fast-moving or perishable prod-ucts such as milk soda eggs bread dairy snacks etc In the chains we studyabout 10ndash20 percent of the products are of a DSD type but that share may reachas much as 40 percent of the products carried [Direct Store Delivery Work Groupet al 1995]

19 The process of changing prices of DSD and of regular products is similarBut with DSD products there are additional costs of the time spent on driving tothe store parking and setting up the price change process at each store

20 Our measures of menu cost also do not incorporate the cost of informingconsumers about price changes which can take a variety of forms such as newspa-per ads and inserts TV and radio ads in-store promotion signs etc Finally wehave no data on lost customer goodwill and damaged reputation caused by dis-crepancies between price tag and cash register [Okun 1981 Carlton and Perloff1994 Haddock and McChesney 1994]

21 The variation in the menu costs across the chains is mostly due to wagerate and labor-efciency variations Also note that since the supermarket chainsin our sample are similar in the size of their stores carry similar sets of productsand follow similar processes of price change and price change decisions it is rea-sonable to believe that the chains incur similar types of costs Therefore as notedunderneath Table III these menu cost measures are computed by replacing theunreported gures by the averages of the available values from the other chains

sures include only the components we could accurately measurein dollar terms which are discussed in subsections III1ndashIII4

IV ITEM PRICING LAWS AND MENU COSTS

In this section we provide evidence on the menu costs for anadditional chain (Chain E) which unlike the other four chainsoperates in a state with an item pricing law The most importantaspect of item pricing laws is that they require a price tag on eachindividual item sold not just on the shelf which is what the otherfour chains in our sample do For example the item pricing lawin Connecticut requires that the grocers ldquoshall mark or cause tobe marked each consumer commodity which bears a UniversalProduct Code with its retail pricerdquo 22 From a menu cost perspec-tive the requirement of posting prices on every item (in additionto the shelf price tag) introduces additional costs in the processof changing prices

Although most of the steps involved in changing prices arethe same for both types of chains stores that are subject to itempricing laws have to undertake additional steps to obey this law23

The labor cost component of menu costs in Chain E totals $75127a year of which $49710 is the cost of the labor time spent onchanging the prices of individual items $3234 is the cost of thelabor time spent on shelf tag replacements and $22183 is thecost of the labor time spent on sign changes (see Table III)24 Anadditional $44168 is spent annually putting prices on new itemsas they are brought to the shelves Although we do not includethis last gure in our menu cost measures because we do not haveinformation on how much of it is due to price change activity andhow much due to just pricingmdashthese costs are clearly a directconsequence of the item pricing law The printing and deliverycost of price tags and price signs are $7644 and the mistake

22 Public Act No 75ndash391 An Act Concerning Pricing of Consumer Merchan-dise [Public Acts of the State of Connecticut 1975 Vol 1 p 390]

23 These steps which are in addition to the regular steps undertaken toreplace price tags on the shelves include (1) obtaining item price tags (2) settingup workstations (3) locating the product (4) removing an item from the shelf (5)removing old price tag (6) setting marking gun (7) applying new price tag and(8) returning the item back to the shelf

24 Since we do not have a measure of the cost of labor time spent on signchanges and the cost of in-store managerial supervision time for this chain weuse the average of the chains that report them (A and D) Note also that thehourly wage rate of $907 paid by Chain E is lower than the hourly wage of about$1400ndash$2000 paid by Chains AndashD

QUARTERLY JOURNAL OF ECONOMICS810

25 Further note that the chains with smaller menu costs are likely tochange their prices more frequently which suggests that the gures of the totalannual menu costs understate the differences between Chain E and the otherchains Indeed despite the large difference in the menu cost per price change thetotal annual menu costs per store for Chain E ($109036) are more comparable tothose of Chains AndashD ($105887)

26 In calculations that follow we use industry averages because (1) thechains did not share this proprietary information with us and (2) we were re-quired to keep the identity of these chains condential as some of these numbersare detailed enough to enable some readers to identify the chains under study

costs are $20799 These gures along with the amount of $5466for the cost of in-store managerial supervision time yield totalannual menu costs of $109036 per store

Although the magnitude of the total annual menu costs seemsimilar to the other four chains note that the average weeklyfrequency of price changes in Chain E is only 1578 which is only403 ( 5 15783916) percent of the price changes made by theother four chains Thus the average menu cost per price changefor Chain E is $133 (see Table IV last row) In contrast the corre-sponding gures for Chains AndashD average $052 Hence the menucosts per price change incurred by the supermarket chain facingitem pricing laws are more than two and a half times the amountincurred by chains that are not subject to this law25 Overallthese ndings suggest that legal restrictions of the type of itempricing laws can have a signicant impact on the menu costs in-curred by sellers

V SIGNIFICANCE OF THE MENU COSTS

The next natural question to ask is how important are thesecosts To address this question we (1) provide several relativemeasures of the menu costs (2) discuss the effect of the menucosts on supermarketsrsquo price change activity and (3) discuss mac-roeconomic implications by relating our ndings to the existingtheoretical models of menu costs In each case we provide addi-tional evidence to help assess the importance of these menu costs

V1 Relative Measures of the Menu Costs

In order to assess the relative magnitude of the menu costsreported in Section IV we now present the menu cost gures rela-tive to the average store-level revenues and net prot margins26

In addition we present the menu cost gures per price changeThe annual average revenues of a large U S supermarket

chain of the type and size included in our sample is $15052716

per store27 According to the second row of Table IV the ratio ofmenu costs to revenues for Chains AndashD ranges between 061ndash076percent averaging 070 percent28 We relate the size of thesegures to the existing theoretical menu cost models in sub-section V3

Net prot margin which measures the revenues minus allcosts is approximately 1ndash3 percent of revenues for these chains[Montgomery 1994] so we use 2 percent as a working averageThe reason for the low prot rate in this industry is the intensecompetition [Calatone et al 1989] especially at the regional level[Chevalier 1995] which has been increasing since the early 1990s[Progressive Grocer November 1992 p 50] It follows that theaverage store protability for these chains equals $301054 peryear Therefore the ratio of total menu cost to net margin forChains AndashD ranges between 304ndash379 percent for an average of352 percent Thus the menu costs we report in this study repre-sent a signicant share of supermarketsrsquo prots

Another way to look at the menu cost gures we report is toexpress them relative to the frequency of price changes In thelast row of Table IV we present the menu cost gures per pricechange for each chain As the table indicates the cost of changinga price in Chains AndashD ranges between $046ndash$068 for an averageof $052 For Chain E the gure is substantially larger $133 perprice change29 These gures are lower than the estimated cost of

27 This is the average of two different estimates $12945432 and$17160000 The source of the rst gure is internal record of a supermarketchain of the type and size studied here The second gure comes from Supermar-ket Business [1993 p 52]

28 We also measured the menu costs in terms of controllable operating ex-penses (which are the portion of costs that the retailer has direct control over andtherefore are often the costs that the retailer is most focused on managing) andgross margins (which measure the supermarket revenues minus direct cost of theproducts it sells) We nd that the menu costs comprise 313 percent of controlla-ble operating expenses and 281 percent of gross margins at these chains on aver-age Finally if we measure the menu costs relative to the number of productscarried per store (about 25000) then we nd that the menu costs per productaverage $423 for Chains AndashD See Table IV and its footnotes for details

29 We can also try to express the menu cost gures relative to the numberof individual items sold by these chains each year (Note the difference betweennumber of products carried and number of items sold As an example a TartarControl Crest 8oz would be considered a product carried and 300 units of themsold per year would be considered number of items sold) Using $170 as the aver-age price of all the products sold we nd that the menu cost per item sold for thefour chains is in the range of $00103ndash$00129 for an average of $00119 (see TableIV second to last row) To see the relative magnitude of these gures note thataccording to Berkowitz Kerin and Rudelius [1986 p 319] the goal of the super-market chains of the type we study ldquo is to make 1 penny of prot on each dollarof salesrdquo Thus menu cost per item sold when adjusted for the average price

THE MAGNITUDE OF MENU COSTS 813

$200ndash$300 per price change reported by Slade [1996a] Thereare several possible reasons for this (1) our menu cost gures arebased on actual measurements of the resources that go into theprice change process whereas she estimates menu costs econo-metrically as model coefcients using a mix of store-level priceand aggregate cost data (2) we cover 25000 products that thesupermarkets carry rather than a single product category (3) ourmenu cost gures do not include all components of menu costsand (4) there could be differences in wage rates that may be im-portant given the signicance of the labor cost component inmenu costs

V2 The Effect of Menu Costs on the Price Change Activity of theSupermarkets

In this section we present evidence which suggests that thesemenu costs may be forming a barrier to price change activity Tobegin with consider the effect of the item pricing law on the pricechange activity of Chain E The data on the weekly frequency ofprice changes in each chain are displayed in the last two rows ofTable I According to these gures the average weekly frequencyof price changes in Chain E is only 1578 Thus on average ChainE changes the prices of only 631 percent of its products eachweek In contrast the average weekly frequency of price changesat Chains AndashD ranges from 3223 to 4316 for the four-chain aver-age of 3916 price changes weekly So Chains AndashD change priceson 1289 to 1726 percent of their products each week yielding afour-chain average of 1566 percent Thus Chain E which facesthe item pricing law changes prices only about one-third timesas frequently as do Chains AndashD30

Moreover within Chain E there are 400 products that areexempt from the item pricing law and thereby face lower menucosts We nd that there are an average of 83 weekly pricechanges for these products yielding 21 percent of these productschanging prices So within Chain E they change prices over threetimes as frequently for products with lower menu costs than for

roughly equals one-half of their target net prot per item which seemssubstantial

30 However note that our comparison of the two types of chains may not becompletely ceteris paribus because these stores are located in different states andtherefore there may be other chain-specic factors (in addition to item pricinglaws) that distinguish these stores We do not have any specic information onthese differences We do know however that the stores in these chains are similarin size and carry similar sets of products

QUARTERLY JOURNAL OF ECONOMICS814

the products with higher menu costs Note that this nding is onthe price change activity within the same chain offering almost anatural experiment on the impact of menu costs on the chainrsquospricing behavior Hence we provide evidence both across chainsas well as across products within a chain that as the costs ofchanging price go up the frequency of price changes goes downThus the menu costs we nd are signicant enough to affect thechainrsquos price change practice

We also have additional evidence from Chains A B and Dabout these menu costs being a barrier to certain price changesand it is summarized in Table V According to the Price Manage-ment Department of Chain A the chain experiences cost in-creases on 860 products in an average week to which it wouldlike to react with a price increase31 However on average 22 per-cent of these price increases are not implemented immediatelybecause the cost of changing prices for these products is too highto make it economically worthwhile Figures of the same magni-tude were reported by other chains For example Chain D experi-ences cost increases for 961 products in an average week Out ofthese the chain adjusts prices of only 633 products The re-maining 34 percent of the prices are left unadjusted because ofthe menu costs Similarly Chain B nds it economically ineffi-cient to adjust prices of 508 ie 30 percent of its products eachweek because of menu costs This provides additional evidencethat the menu costs incurred by these chains are preventing priceadjustments to some costs changes leading to price rigidities ofthe products involved32 Note that although we do not have simi-lar data for Chain E we would expect signicantly lower num-bers on this measure at that chain These gures also suggest anupper bound on the benet of complete price exibility under thecurrent pricing practice of weekly price adjustments Howeverif new technologies (eg ESL systems) and new pricing prac-tices (eg a decentralization of the price change decisions) are

31 Our data contain information only on the frequency of cost increasesAlthough it is more than likely that the supermarkets are experiencing cost de-creases as well our data set contained no information on such decreases

32 Menu costs may even be playing a role in the observed movement towardpricing strategies that rely on fewer price changes such as EDLP [Blattberg andNeslin 1989 Lattin and Ortmeyer 1991 Marketing News April 13 1992 p 8]According to Progressive Grocer [November 1992 p 50] ldquoA growing number ofoperators say they have switched from high-low pricing [to EDLP] They cite theinefciencies of making frequent price changes rdquo Similarly Hoch Dreze andPurk [1994 p 16] state that EDLP lowers operating costs by lowering ldquo in-store labor costs because of less frequent changeovers in special displaysrdquo

adopted allowing a fundamental change in the way the pricingmechanism is currently set the managers could consider morefrequent price change activity (eg multiple times each week) asmenu costs go down

In this paper we measure the menu costs at the chainsrsquo cur-rent level of price change activity It may be worthwhile to specu-late on the shape of the cost function relating menu costs to thefrequency of price changes by assessing how these costs wouldchange if the price change activity were to increase or to decreaseIt seems likely that many of the costs we report in this paper will(approximately) change linearly with additional price changeswithin the current range of price changes the chains are under-taking (plus or minus perhaps a thousand per week) For ex-ample the labor costs associated with changing a shelf price tagcosts of verifying price changes and the costs of mistakes oc-curring during this process all increase linearly with the fre-quency of price changes This is because most of the time-consuming steps involved in the price change process must berepeated each time an additional shelf price tag is changed (seeTable II) Further we were unable to nd many tasks that gener-ated signicant returns to scale It is unclear what cost savingsare available if the price change activity drops substantially be-

low the levels it is at now Clearly if price changes were nearzero or done less frequently than weekly (say monthly) therecould be major differences in these costs

What is less clear is how these costs would change at moreextreme levels of price change activity With less frequent pricechanges the menu costs could probably be reduced signicantlyalthough the cost of deciding what prices to set initially and thecost of putting the initial shelf price tags would still remain as alower bound of the menu cost However for achieving more priceexibility by changing prices more frequently (ie multiple timeseach week) substantial changes must be undertaken At presentthe supermarket chains are set up to make the majority of theirprice changes on a weekly basis with the appropriate systems inplace to make this process most efcient For example in orderto save costs and to have higher quality price tags (eg withcolor more details greater clarity glossy etc) the chains oftensend new price tag requests to a printing shop which takes threedays to print and deliver the labels to each store Then giventhe large number of price changes taking place and the goals ofminimizing customer disruptions and labor costs (such as over-time pay) and coordinating with advertised price promotions theprices are changed in the store over a two-to-three-day period (seeTable VI) The combination of these schedule and built-in lags isacceptable under the current practice of changing prices weeklybut would have to be adjusted dramatically to allow for signifi-cantly more frequent price changes on a regular basis

Perhaps even more imposing are the costs of changing themanagerial costs associated with the current weekly system ofprice changes The process of pricing at this organizational levelis not a self-contained activity taking place in isolation from otheroperations of the supermarket management Rather it is a partof a larger system of business decisions and operations The cur-rent process of operations (such as data collection and theiranalysis management meetings coordination of the decisionsacross functional areas etc) is set up to function on a weeklybasis33 Further these management accounting and logisticssystems are currently built around a tremendous amount of in-

33 For example the data are analyzed and presented to managers on Mon-day and Tuesday with meetings set for Thursday and Friday to make pricingdecisions for the next week in coordination with all other business functions ofthe chain

34 For example under the current system a chainwide category manageroperating at the corporate headquarters needs to study and assess numerouspieces of detailed information such as competitorsrsquo price and sale information fromthe last week the past weekrsquos sales at the own chain manufacturersupplier pro-motions wholesale price reductions coop allowances new product offerings shelfspace decisions coordination with newspaper advertising logistics at the ware-houses as well as at each store store differences in terms of customer characteris-tics and competitive environments productshelf selection and layout etc

35 If the supermarket chains indeed restructure the entire price change pro-cess and begin to change prices much more frequently (say two-to-three times aweek) on a regular basis then the shape of this cost function could change in anunpredictable way

V3 Relating Our Findings to the Existing Theoretical Models ofMenu Costs

In order to assess the magnitude of these menu cost guresin the context of the existing theoretical menu cost literatureconsider the following calculation experiments done within theframework of two theoretical menu cost models Blanchard andKiyotaki [1987] study a general equilibrium menu cost modelwith monopolistic competition and with unit elasticity of aggre-gate demand with respect to real money balances According totheir calculations menu costs of the magnitude of 008 percent ofrevenues which they consider ldquovery smallrdquo may be sufcient toprevent adjustment of prices Ball and Romer [1990] conductsimilar calculations in the framework of a model with imperfectcompetition and menu costs They nd that for plausible markupand labor elasticity parameter values menu costs needed to pre-vent price adjustment are 070 percent of revenues which as theysuggest are nonnegligible For smaller menu costs eg 004 per-cent of the revenue which Ball and Romer consider ldquotrivialrdquo im-plausibly large values of markup and labor elasticity parametersare needed to prevent price adjustment to monetary shocks

According to the gures in Table IV the reported menu costto revenues ratio for Chains AndashD averages 070 percent rangingfrom 061 percent to 076 percent These are signicantly largerthan the ldquotrivialrdquo 004 or 008 percent gures mentioned abovesuggesting that the menu cost gures we nd here are nontrivialFurther under the model and parameter values considered byBlanchard and Kiyotaki [1987] the menu cost gures we nd arehigher than the theoretical minimum needed to form a barrier toprice adjustments Under the model and parameter values con-sidered by Ball and Romer [1990] the reported menu costreve-nue ratio for all but one chain reaches or crosses the theoreticalthreshold of 070 needed to form a barrier to price adjustmentsThe existence of numerous unmeasured menu cost componentsdiscussed in subsection III5 also raises the possibility that theactual menu costs incurred by these chains are signicantlyhigher than that threshold This suggests that the menu costs wereport may be large enough to form a barrier to nominal priceadjustments when interpreted in the context of these models

An issue of interest in this literature is time-dependent ver-sus state-dependent pricing rules (see for example Caplin andLeahy [1991]) The evidence from our data set on the timing of

THE MAGNITUDE OF MENU COSTS 819

price changes suggests that the price change decisions in thesesupermarkets have a strong time-dependent price-setting ele-ment36 For example according to Table VI the prices in Chain Aare changed weekly according to the following schedule the pricechanges of general merchandise that is advertised is done Satur-day nights grocery and produce prices are changed Sundaynights the rest of the general merchandise prices are changed onMonday nights and the prices of advertised grocery items arechanged on Tuesday nights Thus as the gures in Table VI indi-cate over 96 percent of the price changes are done during Sundayand Monday nights However this does not imply that state-dependent pricing rules are unimportant Even if price changesacross product categories follow a prescheduled weekly time ta-ble the prices of which products to change is likely to be a state-dependent decision For example it could depend on changes insupply and demand conditions such as competitorsrsquo price changedecisions Indeed Levy Dutta and Bergen [1996] use retailstore-level orange juice price and cost data to demonstrate thatthe extent of price response to cost shocks that is the extent ofprice rigidity may depend on the nature of supply shocks37

We do not want to overstate the usefulness of our data fordirectly addressing the issue of monetary nonneutrality On onehand authors such as Caplin and Spulber [1987] have demon-strated that under certain conditions individual price rigiditymay not be sufcient for aggregate price rigidity but unfortu-nately our data do not speak directly to this issue38 On the otherhand authors such as Akerlof and Yellen [1985] Mankiw [1985]Parkin [1986] and Caplin and Leahy [1997] have shown that even

36 Danziger [1983] Caballero [1989] and Ball and Mankiw [1994] suggestthat time-dependent price adjustment of the type documented here can be optimalif the cost of gathering information about the state exceeds the cost of making theprice adjustment itself

37 We also considered the possibility of convexities in the cost of changingprices Our data do not suggest many convexities since the labor time spent inthe price tag change process the cost of printing and delivering price tags andin-store supervision time do not change with the size of a price change The onlymeasurable component of menu costs that could be convex is the cost of mistakesmade the larger the price change the higher the probability of a customer notic-ing the mistake and the larger the amount required to be refunded as compensa-tion Among the unmeasured components of menu cost the cost of corporatemanagerial time may increase with the size of a price change because larger pricechanges may require more serious consideration

38 Also see Balke and Wynne [1996] and Bryan and Cecchetti [1996] Sincewe do not have measures of how menu costs change over time our data also havelittle to say about time variation in menu costs or about the relationship betweenmenu costs and ination which during the period of the data collection (1991ndash1992) averaged about 3 percent annually

QUARTERLY JOURNAL OF ECONOMICS820

small menu costs can be relevant since they may be sufcient togenerate substantial aggregate nominal rigidity and thus largebusiness cycles Therefore as Blinder [1994] Kashyap [1995]and Slade [1996a] emphasize it is important to search for directevidence that such costs are indeed present at the micro level Bydirectly identifying documenting and measuring the magnitudeof menu costs at the store level we are taking an important stepin that direction

VI CONCLUSION AND FUTURE RESEARCH

Our main contribution is that we provide direct microeco-nomic evidence on the actual magnitude of menu costs for fourlarge U S retail supermarket chains The annual menu costs perstore at these chains average $105887 comprising 070 percentof revenues 352 percent of net prot margins and $052 perprice change on average

Further we provide evidence which suggests that thesemenu costs may be forming a barrier to price changes Specifi-cally we show that (1) supermarket chains not subject to itempricing law change prices two and a half times more frequentlythan the chain that is subject to the law (2) within the chain thatis subject to the item pricing law they change prices over threetimes as frequently for products that are exempt from this lawthan for the products which are subject to this law and (3) wend that these chains do not adjust prices of up to one-third ofthe products for which they face cost increases because of menucost considerations

When we relate these ndings to the existing theoreticalmodels of menu costs we conclude that the magnitude of menucosts we nd is large enough to be capable of having macroeco-nomic signicance Specically when considered in the context ofthe theoretical menu cost models of Blanchard and Kiyotaki[1987] and Ball and Romer [1990] we nd that the menu costgures we report are ldquonontrivialrdquo and their relative magnitudescross the minimum theoretical threshold needed to form a barrierto price adjustments

Despite the high relative magnitude of the marginal cost ofchanging price that we found the data still indicate frequentweekly price changes This is because of the high marginal bene-t of changing price which is due to the erce competition foundin the retail supermarket industry That marginal benets may

THE MAGNITUDE OF MENU COSTS 821

outweigh the marginal costs of changing prices in this industryhowever does not rule out the possibility that menu costs of themagnitude we nd here can create substantial nominal rigidityin other industries or markets In less competitive industries andmarkets menu costs of the type and magnitude we documenthere are likely to have a bigger impact on the frequency of priceadjustment and consequently on the degree of price rigidity

At a minimum the direct dollar measures of menu costs wereport here can be used as a starting point for future research onmeasuring their magnitude in other industries and establish-ments We anticipate that these menu costs will be similar inother markets which rely on posted prices (such as drugstoresdepartment stores etc) because the steps involved in the pricechange process are likely to be similar What may differ are thefrequency of price changes and the labor wage rates at thesestores For example since supermarket chains change thousandsof prices each week the total annual menu costs incurred bythese chains per store are likely to be high in comparison to otherretail formats such as chain drugstores or department storesThere are however a variety of industries for which the stepsinvolved in changing prices would be signicantly different fromthose reported in our study For example business-to-businesssales which often rely on a sales force will require changes in thelist price sheets changes in the instructions to the sales forcewhich may include education and discussion with the salespeoplein the company and so forth These business-to-business pricesalso often have more complex pricing schemes including quantitydiscounts bundling and individually negotiated prices As an-other example the composition of the cost of changing the news-stand prices of magazines [Cecchetti 1986] or the prices ofproducts sold through catalogs [Kashyap 1995] are different frommany of the menu cost components we discuss here Further thending that a centralization of pricing decisions makes the store-level managerial component of menu cost relatively small sug-gests that the managerial menu costs likely are highest insettings where price change decisions are decentralized Thus fu-ture empirical work should look at menu cost and its compositionin a variety of other industries markets and products with bothcentralized as well as decentralized price change decisions in or-der to see whether the magnitude of these costs can be general-ized and benchmarks can be established Further there aretechnological changes taking place in this and other industries

that promise to alter the structure of menu costs which deserveattention At the theoretical level our ndings suggest that it maybe worthwhile to explore models which incorporate the idea ofitem pricing laws as an additional component of menu costs

THE MAGNITUDE OF MENU COSTS 825

FIGURE IOverview of the Price Change Process

POS denotes Point of Sale and refers to the cash register or the database itis connected to or both For information on the various steps undertaken in eachstage of the price change process and the amount of the labor time spent on mosttime-consuming steps see Table II

Standard price tag changes which include the steps outlined onthe left-hand side of Figure I make up the majority of pricechanges in these chains Some price changes also require addi-tional price signs to be placed at different locations in the storesuch as on an end of aisle display or near the shelf12 These sign

12 These are usually related to the product being on promotion feature ad-vertising display or in-store sale such as ldquomanagerrsquos specialrdquo ldquotodayrsquos specialrdquoetc The steps involved in making sign changes are similar to price changes Themain differences are that (i) the time required for each of the steps in sign changes

changes add to the menu costs and they are outlined on theright-hand side of Figure I the sign change preparation actualsign changes and sign change verication boxes The bottom twoboxes in Figure I are additional menu costs related to the extrasteps taken in these stores to make sure the tag and sign changeshave been done correctly13

Table II lists each stage of the price change process the totalamount of time spent on each stage each week on average andthe number of tasks performed In addition the table identiessome of the main tasks performed in each stage as well as thefour most time-consuming tasks in each stage To compute thetotal labor time used in changing prices on a weekly basis wecombine the data collected through in-store time and motion ob-servations with information on the volume of products for whichprices are changed These weekly hours are multiplied by thewage rates (adjusted for fringe benets) of the employees used inthe price change process to get the total costs of labor required tochange prices

For the four supermarket chains in our study the total an-nual labor cost of changing the shelf price tags ranges from$40027 to $61414 per store for an average of $52084 (see therst row in Table III making up about 49 percent of the totalmenu costs on average The labor cost of changing the price signsrange from $16411 to $27955 per store for an average of$22183 (see the second row in Table III) making up almost 21percent of the menu costs on average Thus for the four super-market chains the total annual menu costs associated with thelabor required to change prices (shelf price tags and price signscombined) range from $62210 to $81703 per store for an annualaverage of $74267 This is the single largest component of themenu costs we report in this study making up about 701 percentof the total menu costs for these chains on average This shouldnot be surprising given that the most signicant portion of retail

are longer because they are in less standard locations and (ii) there are fewersign changes than standard shelf price tag changes

13 The menu cost measures we report do not include the cost of changingprices in cases where items are moved from shelf to shelf or where shelf space isreallocated by increasing the shelf space for some products at the expense of oth-ers However they do include the cost of pricing new products when they are rstintroduced While this could bias the menu cost measures upward since it reallycaptures the cost of pricing rather than the cost of changing price the size of thisbias is marginal due to the small number of new products For example accordingto ESL company executives the number of new products introduced at thesechains each week ranges from 20 to 100 approximately In comparison to the num-ber of products for which prices are changed each week (3223ndash4316) the biasis negligible

grocery operating expenses is labor costs [Hoch Dreze andPurk 1994]14

III2 Costs of Printing and Delivering New Price Tags

There are direct costs associated with printing and deliv-ering the price and sign tags The order must be recorded andprocessed at the chain sent to the printer recorded and pro-cessed at the printer printed packaged and then delivered toeach store The cost per tag is usually quite low $0017 per tagat Chain A which includes stock costs of $00118 per tag impres-sion and data center operator costs of $00037 per tag and mailroom handling costs of $00010 per tag There are however manyprice changes undertaken each week In total the costs of print-ing and delivering the price and sign tags range from $3048 to$10018 averaging $6014 per store per year (see Table III)These costs comprise less than 6 percent of the total menu costswe report

III3 Costs of Mistakes Made in the Process of Changing Prices

Despite the labor put into checking to make sure that theprice changes are done correctly there are still many price mis-takes that are not caught until customers discover them through-out the week and these mistakes impose costs on the chainClearly the costs associated with these errors must be consideredwhen deciding whether to change prices or not and therefore area relevant dimension of menu costs These mistakes can occur sooften that they were a feature of a Dateline segment on U Ssupermarket chains [NBC April 1992] and an article in MoneyMagazine [April 1993] Both the Money Magazine article andGoodstein [1994] report that on average 10 percent of the prod-ucts they examined had price mistakes A more recent study bythe Federal Trade Commission [1996] reports a total error rate ofabout 5 percent

The menu costs associated with these mistakes include lost

14 Our measure of labor cost may overstate the true costs of changing pricesif supermarkets hoard labor to save hiring and ring costs However this is notlikely to be the case for several reasons First the labor costs of changing priceswe report are based on actual measurements of the minimum amount of time andlabor required to accomplish the task rather than on the number of employeeshired to change prices at the store Second the adjustment in the amount of laboris usually done through hours worked which makes cost of hiring and ring lessrelevant And third the workers on the oor are routinely moved from task totask according to the need These tasks include stocking cleaning price changingcustomer service etc The workers employed by supermarket chains are alwaysbusy and so the opportunity cost of changing price is not zero Therefore laborhoarding is not likely to be an important factor in our measurements

QUARTERLY JOURNAL OF ECONOMICS806

cashier time to correct the errors scan guarantee refunds andinventory mistakes associated with incorrect price tags15 Lostcashier time is measured here in terms of wage payments Scanguarantee refunds are additional price reductions beyond the er-ror or additional items given away for free because of the mis-take Finally the inventory mistakes costs we report include onlythe cost of stockouts which occur when shelf price is lower thanintended

The mistake costs were available at Chains A C and D andthey range from $19135 to $20692 for an average of $20140 perstore annually (see Table III) These costs are the second largestcomponent of menu costs in our study comprising about 19 per-cent of the total

III4 Costs of In-Store Supervision Time Spent on ImplementingPrice Changes

Managers at the store level spend time overseeing imple-menting and troubleshooting the price change process OnlyChains A and B had a measure of the menu costs associated withthis in-store supervision time and both of these came from a self-reported number of hours spent on changing prices by the manag-ers at these chains The hours spent on changing prices were thesame across the chains approximately ve hours per week Thusthe menu costs for in-store supervision time came to $4241 and$6692 per store annually for Chains A and B respectively (seeTable III) These costs comprise less than 6 percent of the totalmenu costs we report in this paper However notice that thesemeasures do not include the cost of the management time spenton price change decisions made at corporate headquarters whichis discussed next

III5 Components of Menu Costs We Are Unable to Measure inDollar Terms

Our data set does not contain the exact dollar measures ofsome menu cost components One such component is the cost ofcorporate management time spent on price change decisions16 In

15 Other likely costs of price mistakes that we do not consider explicitlybecause we are unable to measure them in dollar terms are legal problems (whenthe scanner price is higher than the shelf price) loss in customer goodwill anddecreased protability (when the scanner price is lower than the shelf price)

16 It has been suggested that the cost of managerial decisions is one of themost important components of menu cost See for example Ball and Mankiw[1994] Kashyap [1995] and Meltzer [1995] Since the ESL system was not de-

THE MAGNITUDE OF MENU COSTS 807

the supermarket chains we study prices are generally set at cor-porate headquarters in a weekly meeting where the manager incharge of setting prices looks at a variety of information including(a) any manufacturer wholesale price changes promotions andother related issues (b) past sales for this product and (c) com-petitorsrsquo prices Based on this information and on discussionswith other managers the price-setting manager decides whetherto change prices and if so by how much

To estimate the magnitude of these managerial componentsof the menu costs consider the following In an average chainthere is at least one executive of merchandising who devotesmost of hisher time to pricing decisions In addition there areup to three senior managers who would deal with pricing andto whom category managers report There are also ten-to-twelvecategory managers who are responsible for setting prices on allthe products within their category An additional two-to-fourpeople spend full time handling the implementation of pricechanges across retail outlets coordinating the printing and deliv-ery of price tags and handling pricing problems in the systemAnother ve-to-seven workers gather the data on competitorsrsquoprices and analyse both the competitorsrsquo data and the storersquos ownscanner data to put it in a form useable by managers makingpricing decisions Thus in total there are about 21ndash27 peopleworking at the corporate headquarters on price change decisionsAssuming $150000 as the average annual salary of the executiveof merchandising and senior managers $100000 for categorymanagers and $50000 for the rest the chainwide managerialcost falls in the neighborhood of $23ndash$29 million a year whichseems a substantial amount However note that these pricing de-cision are made for the entire chain and therefore the costs perstore are signicantly less especially for the larger chains Forexample using $29 million as the upper bound the additionalannual menu cost per store for Chains AndashD which on averageoperate about 400 stores each averages about $7250 which ismuch lower than expected and is due to the centralization of theprice change decisions in the chains we study17

signed to save the costs of corporate headquarter managerial time spent on pricechange decisions the ESL company did not measure this component of menucosts The estimates reported in this section are based on the information receivedfrom the ESL company executives

17 A decentralization of the price change process say by allowing the store-level managers to make price change decisions can change these gures tremen-dously For example consider the following thought experiment conducted using

QUARTERLY JOURNAL OF ECONOMICS808

Our menu cost measures also do not include the cost ofchanging prices of direct store delivery (DSD) products Theseproducts are almost completely handled by manufacturers in-cluding stocking monitoring inventories and setting and chang-ing prices18 We have data on the weekly frequency of pricechanges of DSD products in Chain E In an average week thereare 174 price changes of DSD products which is about 10 percentof the supermarketrsquos total weekly price changes Using the costof changing the price of a regular product $133 (see Section IVfor details) the annual cost of changing prices of the DSD prod-ucts in this chain roughly equals $1203419 Our menu cost mea-sures do not include these gures since we do not have similardata for the other chains20

III6 Total Menu Costs

The total annual menu costs reported for each chain perstore are listed in the last row of Table III As the table indicatesthe menu costs range from $91416 to $114188 for an average of$105887 per store per year21 Note that these menu cost mea-

the average annual per store gures for Chains AndashD Suppose that the supermar-ket chains decentralize the price change process by hiring for each store only one-quarter of the price change managing team while at the same time they com-pletely eliminate the corporate level team The resulting annual menu cost perstore would be $830887 ( 5 $105887 1 $725000) which would dwarf any of themeasurable menu cost gures we report in this study Even if the average storeonly hired just the merchandising manager at the annual cost of $150000 itwould still incur annual managerial cost of about $255887 ( 5 $105887 1$150000) In other words such a trivial decentralization would double the store-level menu costs This would indeed make the cost of price change decisions themost important component of menu cost

18 DSD products usually are high-volume fast-moving or perishable prod-ucts such as milk soda eggs bread dairy snacks etc In the chains we studyabout 10ndash20 percent of the products are of a DSD type but that share may reachas much as 40 percent of the products carried [Direct Store Delivery Work Groupet al 1995]

19 The process of changing prices of DSD and of regular products is similarBut with DSD products there are additional costs of the time spent on driving tothe store parking and setting up the price change process at each store

20 Our measures of menu cost also do not incorporate the cost of informingconsumers about price changes which can take a variety of forms such as newspa-per ads and inserts TV and radio ads in-store promotion signs etc Finally wehave no data on lost customer goodwill and damaged reputation caused by dis-crepancies between price tag and cash register [Okun 1981 Carlton and Perloff1994 Haddock and McChesney 1994]

21 The variation in the menu costs across the chains is mostly due to wagerate and labor-efciency variations Also note that since the supermarket chainsin our sample are similar in the size of their stores carry similar sets of productsand follow similar processes of price change and price change decisions it is rea-sonable to believe that the chains incur similar types of costs Therefore as notedunderneath Table III these menu cost measures are computed by replacing theunreported gures by the averages of the available values from the other chains

THE MAGNITUDE OF MENU COSTS 809

sures include only the components we could accurately measurein dollar terms which are discussed in subsections III1ndashIII4

IV ITEM PRICING LAWS AND MENU COSTS

In this section we provide evidence on the menu costs for anadditional chain (Chain E) which unlike the other four chainsoperates in a state with an item pricing law The most importantaspect of item pricing laws is that they require a price tag on eachindividual item sold not just on the shelf which is what the otherfour chains in our sample do For example the item pricing lawin Connecticut requires that the grocers ldquoshall mark or cause tobe marked each consumer commodity which bears a UniversalProduct Code with its retail pricerdquo 22 From a menu cost perspec-tive the requirement of posting prices on every item (in additionto the shelf price tag) introduces additional costs in the processof changing prices

Although most of the steps involved in changing prices arethe same for both types of chains stores that are subject to itempricing laws have to undertake additional steps to obey this law23

The labor cost component of menu costs in Chain E totals $75127a year of which $49710 is the cost of the labor time spent onchanging the prices of individual items $3234 is the cost of thelabor time spent on shelf tag replacements and $22183 is thecost of the labor time spent on sign changes (see Table III)24 Anadditional $44168 is spent annually putting prices on new itemsas they are brought to the shelves Although we do not includethis last gure in our menu cost measures because we do not haveinformation on how much of it is due to price change activity andhow much due to just pricingmdashthese costs are clearly a directconsequence of the item pricing law The printing and deliverycost of price tags and price signs are $7644 and the mistake

22 Public Act No 75ndash391 An Act Concerning Pricing of Consumer Merchan-dise [Public Acts of the State of Connecticut 1975 Vol 1 p 390]

23 These steps which are in addition to the regular steps undertaken toreplace price tags on the shelves include (1) obtaining item price tags (2) settingup workstations (3) locating the product (4) removing an item from the shelf (5)removing old price tag (6) setting marking gun (7) applying new price tag and(8) returning the item back to the shelf

24 Since we do not have a measure of the cost of labor time spent on signchanges and the cost of in-store managerial supervision time for this chain weuse the average of the chains that report them (A and D) Note also that thehourly wage rate of $907 paid by Chain E is lower than the hourly wage of about$1400ndash$2000 paid by Chains AndashD

QUARTERLY JOURNAL OF ECONOMICS810

25 Further note that the chains with smaller menu costs are likely tochange their prices more frequently which suggests that the gures of the totalannual menu costs understate the differences between Chain E and the otherchains Indeed despite the large difference in the menu cost per price change thetotal annual menu costs per store for Chain E ($109036) are more comparable tothose of Chains AndashD ($105887)

26 In calculations that follow we use industry averages because (1) thechains did not share this proprietary information with us and (2) we were re-quired to keep the identity of these chains condential as some of these numbersare detailed enough to enable some readers to identify the chains under study

costs are $20799 These gures along with the amount of $5466for the cost of in-store managerial supervision time yield totalannual menu costs of $109036 per store

Although the magnitude of the total annual menu costs seemsimilar to the other four chains note that the average weeklyfrequency of price changes in Chain E is only 1578 which is only403 ( 5 15783916) percent of the price changes made by theother four chains Thus the average menu cost per price changefor Chain E is $133 (see Table IV last row) In contrast the corre-sponding gures for Chains AndashD average $052 Hence the menucosts per price change incurred by the supermarket chain facingitem pricing laws are more than two and a half times the amountincurred by chains that are not subject to this law25 Overallthese ndings suggest that legal restrictions of the type of itempricing laws can have a signicant impact on the menu costs in-curred by sellers

V SIGNIFICANCE OF THE MENU COSTS

The next natural question to ask is how important are thesecosts To address this question we (1) provide several relativemeasures of the menu costs (2) discuss the effect of the menucosts on supermarketsrsquo price change activity and (3) discuss mac-roeconomic implications by relating our ndings to the existingtheoretical models of menu costs In each case we provide addi-tional evidence to help assess the importance of these menu costs

V1 Relative Measures of the Menu Costs

In order to assess the relative magnitude of the menu costsreported in Section IV we now present the menu cost gures rela-tive to the average store-level revenues and net prot margins26

In addition we present the menu cost gures per price changeThe annual average revenues of a large U S supermarket

chain of the type and size included in our sample is $15052716

per store27 According to the second row of Table IV the ratio ofmenu costs to revenues for Chains AndashD ranges between 061ndash076percent averaging 070 percent28 We relate the size of thesegures to the existing theoretical menu cost models in sub-section V3

Net prot margin which measures the revenues minus allcosts is approximately 1ndash3 percent of revenues for these chains[Montgomery 1994] so we use 2 percent as a working averageThe reason for the low prot rate in this industry is the intensecompetition [Calatone et al 1989] especially at the regional level[Chevalier 1995] which has been increasing since the early 1990s[Progressive Grocer November 1992 p 50] It follows that theaverage store protability for these chains equals $301054 peryear Therefore the ratio of total menu cost to net margin forChains AndashD ranges between 304ndash379 percent for an average of352 percent Thus the menu costs we report in this study repre-sent a signicant share of supermarketsrsquo prots

Another way to look at the menu cost gures we report is toexpress them relative to the frequency of price changes In thelast row of Table IV we present the menu cost gures per pricechange for each chain As the table indicates the cost of changinga price in Chains AndashD ranges between $046ndash$068 for an averageof $052 For Chain E the gure is substantially larger $133 perprice change29 These gures are lower than the estimated cost of

27 This is the average of two different estimates $12945432 and$17160000 The source of the rst gure is internal record of a supermarketchain of the type and size studied here The second gure comes from Supermar-ket Business [1993 p 52]

28 We also measured the menu costs in terms of controllable operating ex-penses (which are the portion of costs that the retailer has direct control over andtherefore are often the costs that the retailer is most focused on managing) andgross margins (which measure the supermarket revenues minus direct cost of theproducts it sells) We nd that the menu costs comprise 313 percent of controlla-ble operating expenses and 281 percent of gross margins at these chains on aver-age Finally if we measure the menu costs relative to the number of productscarried per store (about 25000) then we nd that the menu costs per productaverage $423 for Chains AndashD See Table IV and its footnotes for details

29 We can also try to express the menu cost gures relative to the numberof individual items sold by these chains each year (Note the difference betweennumber of products carried and number of items sold As an example a TartarControl Crest 8oz would be considered a product carried and 300 units of themsold per year would be considered number of items sold) Using $170 as the aver-age price of all the products sold we nd that the menu cost per item sold for thefour chains is in the range of $00103ndash$00129 for an average of $00119 (see TableIV second to last row) To see the relative magnitude of these gures note thataccording to Berkowitz Kerin and Rudelius [1986 p 319] the goal of the super-market chains of the type we study ldquo is to make 1 penny of prot on each dollarof salesrdquo Thus menu cost per item sold when adjusted for the average price

THE MAGNITUDE OF MENU COSTS 813

$200ndash$300 per price change reported by Slade [1996a] Thereare several possible reasons for this (1) our menu cost gures arebased on actual measurements of the resources that go into theprice change process whereas she estimates menu costs econo-metrically as model coefcients using a mix of store-level priceand aggregate cost data (2) we cover 25000 products that thesupermarkets carry rather than a single product category (3) ourmenu cost gures do not include all components of menu costsand (4) there could be differences in wage rates that may be im-portant given the signicance of the labor cost component inmenu costs

V2 The Effect of Menu Costs on the Price Change Activity of theSupermarkets

In this section we present evidence which suggests that thesemenu costs may be forming a barrier to price change activity Tobegin with consider the effect of the item pricing law on the pricechange activity of Chain E The data on the weekly frequency ofprice changes in each chain are displayed in the last two rows ofTable I According to these gures the average weekly frequencyof price changes in Chain E is only 1578 Thus on average ChainE changes the prices of only 631 percent of its products eachweek In contrast the average weekly frequency of price changesat Chains AndashD ranges from 3223 to 4316 for the four-chain aver-age of 3916 price changes weekly So Chains AndashD change priceson 1289 to 1726 percent of their products each week yielding afour-chain average of 1566 percent Thus Chain E which facesthe item pricing law changes prices only about one-third timesas frequently as do Chains AndashD30

Moreover within Chain E there are 400 products that areexempt from the item pricing law and thereby face lower menucosts We nd that there are an average of 83 weekly pricechanges for these products yielding 21 percent of these productschanging prices So within Chain E they change prices over threetimes as frequently for products with lower menu costs than for

roughly equals one-half of their target net prot per item which seemssubstantial

30 However note that our comparison of the two types of chains may not becompletely ceteris paribus because these stores are located in different states andtherefore there may be other chain-specic factors (in addition to item pricinglaws) that distinguish these stores We do not have any specic information onthese differences We do know however that the stores in these chains are similarin size and carry similar sets of products

QUARTERLY JOURNAL OF ECONOMICS814

the products with higher menu costs Note that this nding is onthe price change activity within the same chain offering almost anatural experiment on the impact of menu costs on the chainrsquospricing behavior Hence we provide evidence both across chainsas well as across products within a chain that as the costs ofchanging price go up the frequency of price changes goes downThus the menu costs we nd are signicant enough to affect thechainrsquos price change practice

We also have additional evidence from Chains A B and Dabout these menu costs being a barrier to certain price changesand it is summarized in Table V According to the Price Manage-ment Department of Chain A the chain experiences cost in-creases on 860 products in an average week to which it wouldlike to react with a price increase31 However on average 22 per-cent of these price increases are not implemented immediatelybecause the cost of changing prices for these products is too highto make it economically worthwhile Figures of the same magni-tude were reported by other chains For example Chain D experi-ences cost increases for 961 products in an average week Out ofthese the chain adjusts prices of only 633 products The re-maining 34 percent of the prices are left unadjusted because ofthe menu costs Similarly Chain B nds it economically ineffi-cient to adjust prices of 508 ie 30 percent of its products eachweek because of menu costs This provides additional evidencethat the menu costs incurred by these chains are preventing priceadjustments to some costs changes leading to price rigidities ofthe products involved32 Note that although we do not have simi-lar data for Chain E we would expect signicantly lower num-bers on this measure at that chain These gures also suggest anupper bound on the benet of complete price exibility under thecurrent pricing practice of weekly price adjustments Howeverif new technologies (eg ESL systems) and new pricing prac-tices (eg a decentralization of the price change decisions) are

31 Our data contain information only on the frequency of cost increasesAlthough it is more than likely that the supermarkets are experiencing cost de-creases as well our data set contained no information on such decreases

32 Menu costs may even be playing a role in the observed movement towardpricing strategies that rely on fewer price changes such as EDLP [Blattberg andNeslin 1989 Lattin and Ortmeyer 1991 Marketing News April 13 1992 p 8]According to Progressive Grocer [November 1992 p 50] ldquoA growing number ofoperators say they have switched from high-low pricing [to EDLP] They cite theinefciencies of making frequent price changes rdquo Similarly Hoch Dreze andPurk [1994 p 16] state that EDLP lowers operating costs by lowering ldquo in-store labor costs because of less frequent changeovers in special displaysrdquo

adopted allowing a fundamental change in the way the pricingmechanism is currently set the managers could consider morefrequent price change activity (eg multiple times each week) asmenu costs go down

In this paper we measure the menu costs at the chainsrsquo cur-rent level of price change activity It may be worthwhile to specu-late on the shape of the cost function relating menu costs to thefrequency of price changes by assessing how these costs wouldchange if the price change activity were to increase or to decreaseIt seems likely that many of the costs we report in this paper will(approximately) change linearly with additional price changeswithin the current range of price changes the chains are under-taking (plus or minus perhaps a thousand per week) For ex-ample the labor costs associated with changing a shelf price tagcosts of verifying price changes and the costs of mistakes oc-curring during this process all increase linearly with the fre-quency of price changes This is because most of the time-consuming steps involved in the price change process must berepeated each time an additional shelf price tag is changed (seeTable II) Further we were unable to nd many tasks that gener-ated signicant returns to scale It is unclear what cost savingsare available if the price change activity drops substantially be-

QUARTERLY JOURNAL OF ECONOMICS816

low the levels it is at now Clearly if price changes were nearzero or done less frequently than weekly (say monthly) therecould be major differences in these costs

What is less clear is how these costs would change at moreextreme levels of price change activity With less frequent pricechanges the menu costs could probably be reduced signicantlyalthough the cost of deciding what prices to set initially and thecost of putting the initial shelf price tags would still remain as alower bound of the menu cost However for achieving more priceexibility by changing prices more frequently (ie multiple timeseach week) substantial changes must be undertaken At presentthe supermarket chains are set up to make the majority of theirprice changes on a weekly basis with the appropriate systems inplace to make this process most efcient For example in orderto save costs and to have higher quality price tags (eg withcolor more details greater clarity glossy etc) the chains oftensend new price tag requests to a printing shop which takes threedays to print and deliver the labels to each store Then giventhe large number of price changes taking place and the goals ofminimizing customer disruptions and labor costs (such as over-time pay) and coordinating with advertised price promotions theprices are changed in the store over a two-to-three-day period (seeTable VI) The combination of these schedule and built-in lags isacceptable under the current practice of changing prices weeklybut would have to be adjusted dramatically to allow for signifi-cantly more frequent price changes on a regular basis

Perhaps even more imposing are the costs of changing themanagerial costs associated with the current weekly system ofprice changes The process of pricing at this organizational levelis not a self-contained activity taking place in isolation from otheroperations of the supermarket management Rather it is a partof a larger system of business decisions and operations The cur-rent process of operations (such as data collection and theiranalysis management meetings coordination of the decisionsacross functional areas etc) is set up to function on a weeklybasis33 Further these management accounting and logisticssystems are currently built around a tremendous amount of in-

35 If the supermarket chains indeed restructure the entire price change pro-cess and begin to change prices much more frequently (say two-to-three times aweek) on a regular basis then the shape of this cost function could change in anunpredictable way

V3 Relating Our Findings to the Existing Theoretical Models ofMenu Costs

In order to assess the magnitude of these menu cost guresin the context of the existing theoretical menu cost literatureconsider the following calculation experiments done within theframework of two theoretical menu cost models Blanchard andKiyotaki [1987] study a general equilibrium menu cost modelwith monopolistic competition and with unit elasticity of aggre-gate demand with respect to real money balances According totheir calculations menu costs of the magnitude of 008 percent ofrevenues which they consider ldquovery smallrdquo may be sufcient toprevent adjustment of prices Ball and Romer [1990] conductsimilar calculations in the framework of a model with imperfectcompetition and menu costs They nd that for plausible markupand labor elasticity parameter values menu costs needed to pre-vent price adjustment are 070 percent of revenues which as theysuggest are nonnegligible For smaller menu costs eg 004 per-cent of the revenue which Ball and Romer consider ldquotrivialrdquo im-plausibly large values of markup and labor elasticity parametersare needed to prevent price adjustment to monetary shocks

According to the gures in Table IV the reported menu costto revenues ratio for Chains AndashD averages 070 percent rangingfrom 061 percent to 076 percent These are signicantly largerthan the ldquotrivialrdquo 004 or 008 percent gures mentioned abovesuggesting that the menu cost gures we nd here are nontrivialFurther under the model and parameter values considered byBlanchard and Kiyotaki [1987] the menu cost gures we nd arehigher than the theoretical minimum needed to form a barrier toprice adjustments Under the model and parameter values con-sidered by Ball and Romer [1990] the reported menu costreve-nue ratio for all but one chain reaches or crosses the theoreticalthreshold of 070 needed to form a barrier to price adjustmentsThe existence of numerous unmeasured menu cost componentsdiscussed in subsection III5 also raises the possibility that theactual menu costs incurred by these chains are signicantlyhigher than that threshold This suggests that the menu costs wereport may be large enough to form a barrier to nominal priceadjustments when interpreted in the context of these models

An issue of interest in this literature is time-dependent ver-sus state-dependent pricing rules (see for example Caplin andLeahy [1991]) The evidence from our data set on the timing of

THE MAGNITUDE OF MENU COSTS 819

price changes suggests that the price change decisions in thesesupermarkets have a strong time-dependent price-setting ele-ment36 For example according to Table VI the prices in Chain Aare changed weekly according to the following schedule the pricechanges of general merchandise that is advertised is done Satur-day nights grocery and produce prices are changed Sundaynights the rest of the general merchandise prices are changed onMonday nights and the prices of advertised grocery items arechanged on Tuesday nights Thus as the gures in Table VI indi-cate over 96 percent of the price changes are done during Sundayand Monday nights However this does not imply that state-dependent pricing rules are unimportant Even if price changesacross product categories follow a prescheduled weekly time ta-ble the prices of which products to change is likely to be a state-dependent decision For example it could depend on changes insupply and demand conditions such as competitorsrsquo price changedecisions Indeed Levy Dutta and Bergen [1996] use retailstore-level orange juice price and cost data to demonstrate thatthe extent of price response to cost shocks that is the extent ofprice rigidity may depend on the nature of supply shocks37

We do not want to overstate the usefulness of our data fordirectly addressing the issue of monetary nonneutrality On onehand authors such as Caplin and Spulber [1987] have demon-strated that under certain conditions individual price rigiditymay not be sufcient for aggregate price rigidity but unfortu-nately our data do not speak directly to this issue38 On the otherhand authors such as Akerlof and Yellen [1985] Mankiw [1985]Parkin [1986] and Caplin and Leahy [1997] have shown that even

36 Danziger [1983] Caballero [1989] and Ball and Mankiw [1994] suggestthat time-dependent price adjustment of the type documented here can be optimalif the cost of gathering information about the state exceeds the cost of making theprice adjustment itself

37 We also considered the possibility of convexities in the cost of changingprices Our data do not suggest many convexities since the labor time spent inthe price tag change process the cost of printing and delivering price tags andin-store supervision time do not change with the size of a price change The onlymeasurable component of menu costs that could be convex is the cost of mistakesmade the larger the price change the higher the probability of a customer notic-ing the mistake and the larger the amount required to be refunded as compensa-tion Among the unmeasured components of menu cost the cost of corporatemanagerial time may increase with the size of a price change because larger pricechanges may require more serious consideration

38 Also see Balke and Wynne [1996] and Bryan and Cecchetti [1996] Sincewe do not have measures of how menu costs change over time our data also havelittle to say about time variation in menu costs or about the relationship betweenmenu costs and ination which during the period of the data collection (1991ndash1992) averaged about 3 percent annually

QUARTERLY JOURNAL OF ECONOMICS820

small menu costs can be relevant since they may be sufcient togenerate substantial aggregate nominal rigidity and thus largebusiness cycles Therefore as Blinder [1994] Kashyap [1995]and Slade [1996a] emphasize it is important to search for directevidence that such costs are indeed present at the micro level Bydirectly identifying documenting and measuring the magnitudeof menu costs at the store level we are taking an important stepin that direction

VI CONCLUSION AND FUTURE RESEARCH

Our main contribution is that we provide direct microeco-nomic evidence on the actual magnitude of menu costs for fourlarge U S retail supermarket chains The annual menu costs perstore at these chains average $105887 comprising 070 percentof revenues 352 percent of net prot margins and $052 perprice change on average

Further we provide evidence which suggests that thesemenu costs may be forming a barrier to price changes Specifi-cally we show that (1) supermarket chains not subject to itempricing law change prices two and a half times more frequentlythan the chain that is subject to the law (2) within the chain thatis subject to the item pricing law they change prices over threetimes as frequently for products that are exempt from this lawthan for the products which are subject to this law and (3) wend that these chains do not adjust prices of up to one-third ofthe products for which they face cost increases because of menucost considerations

When we relate these ndings to the existing theoreticalmodels of menu costs we conclude that the magnitude of menucosts we nd is large enough to be capable of having macroeco-nomic signicance Specically when considered in the context ofthe theoretical menu cost models of Blanchard and Kiyotaki[1987] and Ball and Romer [1990] we nd that the menu costgures we report are ldquonontrivialrdquo and their relative magnitudescross the minimum theoretical threshold needed to form a barrierto price adjustments

Despite the high relative magnitude of the marginal cost ofchanging price that we found the data still indicate frequentweekly price changes This is because of the high marginal bene-t of changing price which is due to the erce competition foundin the retail supermarket industry That marginal benets may

THE MAGNITUDE OF MENU COSTS 821

outweigh the marginal costs of changing prices in this industryhowever does not rule out the possibility that menu costs of themagnitude we nd here can create substantial nominal rigidityin other industries or markets In less competitive industries andmarkets menu costs of the type and magnitude we documenthere are likely to have a bigger impact on the frequency of priceadjustment and consequently on the degree of price rigidity

At a minimum the direct dollar measures of menu costs wereport here can be used as a starting point for future research onmeasuring their magnitude in other industries and establish-ments We anticipate that these menu costs will be similar inother markets which rely on posted prices (such as drugstoresdepartment stores etc) because the steps involved in the pricechange process are likely to be similar What may differ are thefrequency of price changes and the labor wage rates at thesestores For example since supermarket chains change thousandsof prices each week the total annual menu costs incurred bythese chains per store are likely to be high in comparison to otherretail formats such as chain drugstores or department storesThere are however a variety of industries for which the stepsinvolved in changing prices would be signicantly different fromthose reported in our study For example business-to-businesssales which often rely on a sales force will require changes in thelist price sheets changes in the instructions to the sales forcewhich may include education and discussion with the salespeoplein the company and so forth These business-to-business pricesalso often have more complex pricing schemes including quantitydiscounts bundling and individually negotiated prices As an-other example the composition of the cost of changing the news-stand prices of magazines [Cecchetti 1986] or the prices ofproducts sold through catalogs [Kashyap 1995] are different frommany of the menu cost components we discuss here Further thending that a centralization of pricing decisions makes the store-level managerial component of menu cost relatively small sug-gests that the managerial menu costs likely are highest insettings where price change decisions are decentralized Thus fu-ture empirical work should look at menu cost and its compositionin a variety of other industries markets and products with bothcentralized as well as decentralized price change decisions in or-der to see whether the magnitude of these costs can be general-ized and benchmarks can be established Further there aretechnological changes taking place in this and other industries

that promise to alter the structure of menu costs which deserveattention At the theoretical level our ndings suggest that it maybe worthwhile to explore models which incorporate the idea ofitem pricing laws as an additional component of menu costs

THE MAGNITUDE OF MENU COSTS 825

changes add to the menu costs and they are outlined on theright-hand side of Figure I the sign change preparation actualsign changes and sign change verication boxes The bottom twoboxes in Figure I are additional menu costs related to the extrasteps taken in these stores to make sure the tag and sign changeshave been done correctly13

Table II lists each stage of the price change process the totalamount of time spent on each stage each week on average andthe number of tasks performed In addition the table identiessome of the main tasks performed in each stage as well as thefour most time-consuming tasks in each stage To compute thetotal labor time used in changing prices on a weekly basis wecombine the data collected through in-store time and motion ob-servations with information on the volume of products for whichprices are changed These weekly hours are multiplied by thewage rates (adjusted for fringe benets) of the employees used inthe price change process to get the total costs of labor required tochange prices

For the four supermarket chains in our study the total an-nual labor cost of changing the shelf price tags ranges from$40027 to $61414 per store for an average of $52084 (see therst row in Table III making up about 49 percent of the totalmenu costs on average The labor cost of changing the price signsrange from $16411 to $27955 per store for an average of$22183 (see the second row in Table III) making up almost 21percent of the menu costs on average Thus for the four super-market chains the total annual menu costs associated with thelabor required to change prices (shelf price tags and price signscombined) range from $62210 to $81703 per store for an annualaverage of $74267 This is the single largest component of themenu costs we report in this study making up about 701 percentof the total menu costs for these chains on average This shouldnot be surprising given that the most signicant portion of retail

are longer because they are in less standard locations and (ii) there are fewersign changes than standard shelf price tag changes

13 The menu cost measures we report do not include the cost of changingprices in cases where items are moved from shelf to shelf or where shelf space isreallocated by increasing the shelf space for some products at the expense of oth-ers However they do include the cost of pricing new products when they are rstintroduced While this could bias the menu cost measures upward since it reallycaptures the cost of pricing rather than the cost of changing price the size of thisbias is marginal due to the small number of new products For example accordingto ESL company executives the number of new products introduced at thesechains each week ranges from 20 to 100 approximately In comparison to the num-ber of products for which prices are changed each week (3223ndash4316) the biasis negligible

Despite the labor put into checking to make sure that theprice changes are done correctly there are still many price mis-takes that are not caught until customers discover them through-out the week and these mistakes impose costs on the chainClearly the costs associated with these errors must be consideredwhen deciding whether to change prices or not and therefore area relevant dimension of menu costs These mistakes can occur sooften that they were a feature of a Dateline segment on U Ssupermarket chains [NBC April 1992] and an article in MoneyMagazine [April 1993] Both the Money Magazine article andGoodstein [1994] report that on average 10 percent of the prod-ucts they examined had price mistakes A more recent study bythe Federal Trade Commission [1996] reports a total error rate ofabout 5 percent

The menu costs associated with these mistakes include lost

14 Our measure of labor cost may overstate the true costs of changing pricesif supermarkets hoard labor to save hiring and ring costs However this is notlikely to be the case for several reasons First the labor costs of changing priceswe report are based on actual measurements of the minimum amount of time andlabor required to accomplish the task rather than on the number of employeeshired to change prices at the store Second the adjustment in the amount of laboris usually done through hours worked which makes cost of hiring and ring lessrelevant And third the workers on the oor are routinely moved from task totask according to the need These tasks include stocking cleaning price changingcustomer service etc The workers employed by supermarket chains are alwaysbusy and so the opportunity cost of changing price is not zero Therefore laborhoarding is not likely to be an important factor in our measurements

cashier time to correct the errors scan guarantee refunds andinventory mistakes associated with incorrect price tags15 Lostcashier time is measured here in terms of wage payments Scanguarantee refunds are additional price reductions beyond the er-ror or additional items given away for free because of the mis-take Finally the inventory mistakes costs we report include onlythe cost of stockouts which occur when shelf price is lower thanintended

The mistake costs were available at Chains A C and D andthey range from $19135 to $20692 for an average of $20140 perstore annually (see Table III) These costs are the second largestcomponent of menu costs in our study comprising about 19 per-cent of the total

III4 Costs of In-Store Supervision Time Spent on ImplementingPrice Changes

Managers at the store level spend time overseeing imple-menting and troubleshooting the price change process OnlyChains A and B had a measure of the menu costs associated withthis in-store supervision time and both of these came from a self-reported number of hours spent on changing prices by the manag-ers at these chains The hours spent on changing prices were thesame across the chains approximately ve hours per week Thusthe menu costs for in-store supervision time came to $4241 and$6692 per store annually for Chains A and B respectively (seeTable III) These costs comprise less than 6 percent of the totalmenu costs we report in this paper However notice that thesemeasures do not include the cost of the management time spenton price change decisions made at corporate headquarters whichis discussed next

III5 Components of Menu Costs We Are Unable to Measure inDollar Terms

Our data set does not contain the exact dollar measures ofsome menu cost components One such component is the cost ofcorporate management time spent on price change decisions16 In

15 Other likely costs of price mistakes that we do not consider explicitlybecause we are unable to measure them in dollar terms are legal problems (whenthe scanner price is higher than the shelf price) loss in customer goodwill anddecreased protability (when the scanner price is lower than the shelf price)

16 It has been suggested that the cost of managerial decisions is one of themost important components of menu cost See for example Ball and Mankiw[1994] Kashyap [1995] and Meltzer [1995] Since the ESL system was not de-

THE MAGNITUDE OF MENU COSTS 807

the supermarket chains we study prices are generally set at cor-porate headquarters in a weekly meeting where the manager incharge of setting prices looks at a variety of information including(a) any manufacturer wholesale price changes promotions andother related issues (b) past sales for this product and (c) com-petitorsrsquo prices Based on this information and on discussionswith other managers the price-setting manager decides whetherto change prices and if so by how much

To estimate the magnitude of these managerial componentsof the menu costs consider the following In an average chainthere is at least one executive of merchandising who devotesmost of hisher time to pricing decisions In addition there areup to three senior managers who would deal with pricing andto whom category managers report There are also ten-to-twelvecategory managers who are responsible for setting prices on allthe products within their category An additional two-to-fourpeople spend full time handling the implementation of pricechanges across retail outlets coordinating the printing and deliv-ery of price tags and handling pricing problems in the systemAnother ve-to-seven workers gather the data on competitorsrsquoprices and analyse both the competitorsrsquo data and the storersquos ownscanner data to put it in a form useable by managers makingpricing decisions Thus in total there are about 21ndash27 peopleworking at the corporate headquarters on price change decisionsAssuming $150000 as the average annual salary of the executiveof merchandising and senior managers $100000 for categorymanagers and $50000 for the rest the chainwide managerialcost falls in the neighborhood of $23ndash$29 million a year whichseems a substantial amount However note that these pricing de-cision are made for the entire chain and therefore the costs perstore are signicantly less especially for the larger chains Forexample using $29 million as the upper bound the additionalannual menu cost per store for Chains AndashD which on averageoperate about 400 stores each averages about $7250 which ismuch lower than expected and is due to the centralization of theprice change decisions in the chains we study17

signed to save the costs of corporate headquarter managerial time spent on pricechange decisions the ESL company did not measure this component of menucosts The estimates reported in this section are based on the information receivedfrom the ESL company executives

17 A decentralization of the price change process say by allowing the store-level managers to make price change decisions can change these gures tremen-dously For example consider the following thought experiment conducted using

QUARTERLY JOURNAL OF ECONOMICS808

Our menu cost measures also do not include the cost ofchanging prices of direct store delivery (DSD) products Theseproducts are almost completely handled by manufacturers in-cluding stocking monitoring inventories and setting and chang-ing prices18 We have data on the weekly frequency of pricechanges of DSD products in Chain E In an average week thereare 174 price changes of DSD products which is about 10 percentof the supermarketrsquos total weekly price changes Using the costof changing the price of a regular product $133 (see Section IVfor details) the annual cost of changing prices of the DSD prod-ucts in this chain roughly equals $1203419 Our menu cost mea-sures do not include these gures since we do not have similardata for the other chains20

III6 Total Menu Costs

The total annual menu costs reported for each chain perstore are listed in the last row of Table III As the table indicatesthe menu costs range from $91416 to $114188 for an average of$105887 per store per year21 Note that these menu cost mea-

the average annual per store gures for Chains AndashD Suppose that the supermar-ket chains decentralize the price change process by hiring for each store only one-quarter of the price change managing team while at the same time they com-pletely eliminate the corporate level team The resulting annual menu cost perstore would be $830887 ( 5 $105887 1 $725000) which would dwarf any of themeasurable menu cost gures we report in this study Even if the average storeonly hired just the merchandising manager at the annual cost of $150000 itwould still incur annual managerial cost of about $255887 ( 5 $105887 1$150000) In other words such a trivial decentralization would double the store-level menu costs This would indeed make the cost of price change decisions themost important component of menu cost

18 DSD products usually are high-volume fast-moving or perishable prod-ucts such as milk soda eggs bread dairy snacks etc In the chains we studyabout 10ndash20 percent of the products are of a DSD type but that share may reachas much as 40 percent of the products carried [Direct Store Delivery Work Groupet al 1995]

19 The process of changing prices of DSD and of regular products is similarBut with DSD products there are additional costs of the time spent on driving tothe store parking and setting up the price change process at each store

20 Our measures of menu cost also do not incorporate the cost of informingconsumers about price changes which can take a variety of forms such as newspa-per ads and inserts TV and radio ads in-store promotion signs etc Finally wehave no data on lost customer goodwill and damaged reputation caused by dis-crepancies between price tag and cash register [Okun 1981 Carlton and Perloff1994 Haddock and McChesney 1994]

21 The variation in the menu costs across the chains is mostly due to wagerate and labor-efciency variations Also note that since the supermarket chainsin our sample are similar in the size of their stores carry similar sets of productsand follow similar processes of price change and price change decisions it is rea-sonable to believe that the chains incur similar types of costs Therefore as notedunderneath Table III these menu cost measures are computed by replacing theunreported gures by the averages of the available values from the other chains

THE MAGNITUDE OF MENU COSTS 809

sures include only the components we could accurately measurein dollar terms which are discussed in subsections III1ndashIII4

IV ITEM PRICING LAWS AND MENU COSTS

In this section we provide evidence on the menu costs for anadditional chain (Chain E) which unlike the other four chainsoperates in a state with an item pricing law The most importantaspect of item pricing laws is that they require a price tag on eachindividual item sold not just on the shelf which is what the otherfour chains in our sample do For example the item pricing lawin Connecticut requires that the grocers ldquoshall mark or cause tobe marked each consumer commodity which bears a UniversalProduct Code with its retail pricerdquo 22 From a menu cost perspec-tive the requirement of posting prices on every item (in additionto the shelf price tag) introduces additional costs in the processof changing prices

Although most of the steps involved in changing prices arethe same for both types of chains stores that are subject to itempricing laws have to undertake additional steps to obey this law23

The labor cost component of menu costs in Chain E totals $75127a year of which $49710 is the cost of the labor time spent onchanging the prices of individual items $3234 is the cost of thelabor time spent on shelf tag replacements and $22183 is thecost of the labor time spent on sign changes (see Table III)24 Anadditional $44168 is spent annually putting prices on new itemsas they are brought to the shelves Although we do not includethis last gure in our menu cost measures because we do not haveinformation on how much of it is due to price change activity andhow much due to just pricingmdashthese costs are clearly a directconsequence of the item pricing law The printing and deliverycost of price tags and price signs are $7644 and the mistake

22 Public Act No 75ndash391 An Act Concerning Pricing of Consumer Merchan-dise [Public Acts of the State of Connecticut 1975 Vol 1 p 390]

23 These steps which are in addition to the regular steps undertaken toreplace price tags on the shelves include (1) obtaining item price tags (2) settingup workstations (3) locating the product (4) removing an item from the shelf (5)removing old price tag (6) setting marking gun (7) applying new price tag and(8) returning the item back to the shelf

24 Since we do not have a measure of the cost of labor time spent on signchanges and the cost of in-store managerial supervision time for this chain weuse the average of the chains that report them (A and D) Note also that thehourly wage rate of $907 paid by Chain E is lower than the hourly wage of about$1400ndash$2000 paid by Chains AndashD

QUARTERLY JOURNAL OF ECONOMICS810

25 Further note that the chains with smaller menu costs are likely tochange their prices more frequently which suggests that the gures of the totalannual menu costs understate the differences between Chain E and the otherchains Indeed despite the large difference in the menu cost per price change thetotal annual menu costs per store for Chain E ($109036) are more comparable tothose of Chains AndashD ($105887)

26 In calculations that follow we use industry averages because (1) thechains did not share this proprietary information with us and (2) we were re-quired to keep the identity of these chains condential as some of these numbersare detailed enough to enable some readers to identify the chains under study

costs are $20799 These gures along with the amount of $5466for the cost of in-store managerial supervision time yield totalannual menu costs of $109036 per store

Although the magnitude of the total annual menu costs seemsimilar to the other four chains note that the average weeklyfrequency of price changes in Chain E is only 1578 which is only403 ( 5 15783916) percent of the price changes made by theother four chains Thus the average menu cost per price changefor Chain E is $133 (see Table IV last row) In contrast the corre-sponding gures for Chains AndashD average $052 Hence the menucosts per price change incurred by the supermarket chain facingitem pricing laws are more than two and a half times the amountincurred by chains that are not subject to this law25 Overallthese ndings suggest that legal restrictions of the type of itempricing laws can have a signicant impact on the menu costs in-curred by sellers

V SIGNIFICANCE OF THE MENU COSTS

The next natural question to ask is how important are thesecosts To address this question we (1) provide several relativemeasures of the menu costs (2) discuss the effect of the menucosts on supermarketsrsquo price change activity and (3) discuss mac-roeconomic implications by relating our ndings to the existingtheoretical models of menu costs In each case we provide addi-tional evidence to help assess the importance of these menu costs

V1 Relative Measures of the Menu Costs

In order to assess the relative magnitude of the menu costsreported in Section IV we now present the menu cost gures rela-tive to the average store-level revenues and net prot margins26

In addition we present the menu cost gures per price changeThe annual average revenues of a large U S supermarket

chain of the type and size included in our sample is $15052716

per store27 According to the second row of Table IV the ratio ofmenu costs to revenues for Chains AndashD ranges between 061ndash076percent averaging 070 percent28 We relate the size of thesegures to the existing theoretical menu cost models in sub-section V3

Net prot margin which measures the revenues minus allcosts is approximately 1ndash3 percent of revenues for these chains[Montgomery 1994] so we use 2 percent as a working averageThe reason for the low prot rate in this industry is the intensecompetition [Calatone et al 1989] especially at the regional level[Chevalier 1995] which has been increasing since the early 1990s[Progressive Grocer November 1992 p 50] It follows that theaverage store protability for these chains equals $301054 peryear Therefore the ratio of total menu cost to net margin forChains AndashD ranges between 304ndash379 percent for an average of352 percent Thus the menu costs we report in this study repre-sent a signicant share of supermarketsrsquo prots

Another way to look at the menu cost gures we report is toexpress them relative to the frequency of price changes In thelast row of Table IV we present the menu cost gures per pricechange for each chain As the table indicates the cost of changinga price in Chains AndashD ranges between $046ndash$068 for an averageof $052 For Chain E the gure is substantially larger $133 perprice change29 These gures are lower than the estimated cost of

27 This is the average of two different estimates $12945432 and$17160000 The source of the rst gure is internal record of a supermarketchain of the type and size studied here The second gure comes from Supermar-ket Business [1993 p 52]

28 We also measured the menu costs in terms of controllable operating ex-penses (which are the portion of costs that the retailer has direct control over andtherefore are often the costs that the retailer is most focused on managing) andgross margins (which measure the supermarket revenues minus direct cost of theproducts it sells) We nd that the menu costs comprise 313 percent of controlla-ble operating expenses and 281 percent of gross margins at these chains on aver-age Finally if we measure the menu costs relative to the number of productscarried per store (about 25000) then we nd that the menu costs per productaverage $423 for Chains AndashD See Table IV and its footnotes for details

29 We can also try to express the menu cost gures relative to the numberof individual items sold by these chains each year (Note the difference betweennumber of products carried and number of items sold As an example a TartarControl Crest 8oz would be considered a product carried and 300 units of themsold per year would be considered number of items sold) Using $170 as the aver-age price of all the products sold we nd that the menu cost per item sold for thefour chains is in the range of $00103ndash$00129 for an average of $00119 (see TableIV second to last row) To see the relative magnitude of these gures note thataccording to Berkowitz Kerin and Rudelius [1986 p 319] the goal of the super-market chains of the type we study ldquo is to make 1 penny of prot on each dollarof salesrdquo Thus menu cost per item sold when adjusted for the average price

THE MAGNITUDE OF MENU COSTS 813

$200ndash$300 per price change reported by Slade [1996a] Thereare several possible reasons for this (1) our menu cost gures arebased on actual measurements of the resources that go into theprice change process whereas she estimates menu costs econo-metrically as model coefcients using a mix of store-level priceand aggregate cost data (2) we cover 25000 products that thesupermarkets carry rather than a single product category (3) ourmenu cost gures do not include all components of menu costsand (4) there could be differences in wage rates that may be im-portant given the signicance of the labor cost component inmenu costs

V2 The Effect of Menu Costs on the Price Change Activity of theSupermarkets

In this section we present evidence which suggests that thesemenu costs may be forming a barrier to price change activity Tobegin with consider the effect of the item pricing law on the pricechange activity of Chain E The data on the weekly frequency ofprice changes in each chain are displayed in the last two rows ofTable I According to these gures the average weekly frequencyof price changes in Chain E is only 1578 Thus on average ChainE changes the prices of only 631 percent of its products eachweek In contrast the average weekly frequency of price changesat Chains AndashD ranges from 3223 to 4316 for the four-chain aver-age of 3916 price changes weekly So Chains AndashD change priceson 1289 to 1726 percent of their products each week yielding afour-chain average of 1566 percent Thus Chain E which facesthe item pricing law changes prices only about one-third timesas frequently as do Chains AndashD30

Moreover within Chain E there are 400 products that areexempt from the item pricing law and thereby face lower menucosts We nd that there are an average of 83 weekly pricechanges for these products yielding 21 percent of these productschanging prices So within Chain E they change prices over threetimes as frequently for products with lower menu costs than for

roughly equals one-half of their target net prot per item which seemssubstantial

30 However note that our comparison of the two types of chains may not becompletely ceteris paribus because these stores are located in different states andtherefore there may be other chain-specic factors (in addition to item pricinglaws) that distinguish these stores We do not have any specic information onthese differences We do know however that the stores in these chains are similarin size and carry similar sets of products

QUARTERLY JOURNAL OF ECONOMICS814

the products with higher menu costs Note that this nding is onthe price change activity within the same chain offering almost anatural experiment on the impact of menu costs on the chainrsquospricing behavior Hence we provide evidence both across chainsas well as across products within a chain that as the costs ofchanging price go up the frequency of price changes goes downThus the menu costs we nd are signicant enough to affect thechainrsquos price change practice

We also have additional evidence from Chains A B and Dabout these menu costs being a barrier to certain price changesand it is summarized in Table V According to the Price Manage-ment Department of Chain A the chain experiences cost in-creases on 860 products in an average week to which it wouldlike to react with a price increase31 However on average 22 per-cent of these price increases are not implemented immediatelybecause the cost of changing prices for these products is too highto make it economically worthwhile Figures of the same magni-tude were reported by other chains For example Chain D experi-ences cost increases for 961 products in an average week Out ofthese the chain adjusts prices of only 633 products The re-maining 34 percent of the prices are left unadjusted because ofthe menu costs Similarly Chain B nds it economically ineffi-cient to adjust prices of 508 ie 30 percent of its products eachweek because of menu costs This provides additional evidencethat the menu costs incurred by these chains are preventing priceadjustments to some costs changes leading to price rigidities ofthe products involved32 Note that although we do not have simi-lar data for Chain E we would expect signicantly lower num-bers on this measure at that chain These gures also suggest anupper bound on the benet of complete price exibility under thecurrent pricing practice of weekly price adjustments Howeverif new technologies (eg ESL systems) and new pricing prac-tices (eg a decentralization of the price change decisions) are

31 Our data contain information only on the frequency of cost increasesAlthough it is more than likely that the supermarkets are experiencing cost de-creases as well our data set contained no information on such decreases

32 Menu costs may even be playing a role in the observed movement towardpricing strategies that rely on fewer price changes such as EDLP [Blattberg andNeslin 1989 Lattin and Ortmeyer 1991 Marketing News April 13 1992 p 8]According to Progressive Grocer [November 1992 p 50] ldquoA growing number ofoperators say they have switched from high-low pricing [to EDLP] They cite theinefciencies of making frequent price changes rdquo Similarly Hoch Dreze andPurk [1994 p 16] state that EDLP lowers operating costs by lowering ldquo in-store labor costs because of less frequent changeovers in special displaysrdquo

adopted allowing a fundamental change in the way the pricingmechanism is currently set the managers could consider morefrequent price change activity (eg multiple times each week) asmenu costs go down

In this paper we measure the menu costs at the chainsrsquo cur-rent level of price change activity It may be worthwhile to specu-late on the shape of the cost function relating menu costs to thefrequency of price changes by assessing how these costs wouldchange if the price change activity were to increase or to decreaseIt seems likely that many of the costs we report in this paper will(approximately) change linearly with additional price changeswithin the current range of price changes the chains are under-taking (plus or minus perhaps a thousand per week) For ex-ample the labor costs associated with changing a shelf price tagcosts of verifying price changes and the costs of mistakes oc-curring during this process all increase linearly with the fre-quency of price changes This is because most of the time-consuming steps involved in the price change process must berepeated each time an additional shelf price tag is changed (seeTable II) Further we were unable to nd many tasks that gener-ated signicant returns to scale It is unclear what cost savingsare available if the price change activity drops substantially be-

low the levels it is at now Clearly if price changes were nearzero or done less frequently than weekly (say monthly) therecould be major differences in these costs

What is less clear is how these costs would change at moreextreme levels of price change activity With less frequent pricechanges the menu costs could probably be reduced signicantlyalthough the cost of deciding what prices to set initially and thecost of putting the initial shelf price tags would still remain as alower bound of the menu cost However for achieving more priceexibility by changing prices more frequently (ie multiple timeseach week) substantial changes must be undertaken At presentthe supermarket chains are set up to make the majority of theirprice changes on a weekly basis with the appropriate systems inplace to make this process most efcient For example in orderto save costs and to have higher quality price tags (eg withcolor more details greater clarity glossy etc) the chains oftensend new price tag requests to a printing shop which takes threedays to print and deliver the labels to each store Then giventhe large number of price changes taking place and the goals ofminimizing customer disruptions and labor costs (such as over-time pay) and coordinating with advertised price promotions theprices are changed in the store over a two-to-three-day period (seeTable VI) The combination of these schedule and built-in lags isacceptable under the current practice of changing prices weeklybut would have to be adjusted dramatically to allow for signifi-cantly more frequent price changes on a regular basis

Perhaps even more imposing are the costs of changing themanagerial costs associated with the current weekly system ofprice changes The process of pricing at this organizational levelis not a self-contained activity taking place in isolation from otheroperations of the supermarket management Rather it is a partof a larger system of business decisions and operations The cur-rent process of operations (such as data collection and theiranalysis management meetings coordination of the decisionsacross functional areas etc) is set up to function on a weeklybasis33 Further these management accounting and logisticssystems are currently built around a tremendous amount of in-

formation to be analyzed for thousands of products34 Accommo-dating more frequent price changes on a regular basis wouldrequire a radical adjustment of many managerial substructuresand units at both corporate and store levels which could involvecostly investment in restructuring and retraining the existing la-bor force as well as in new physical and human capital Thus thecost function relating the menu costs to the frequency of pricechanges would be approximately linear from zero to roughlyabout 5000 price changes per week With higher frequency ofprice changes under the current weekly pricing practice themenu costs are likely to increase dramatically perhaps by asmuch as ten-to-twenty times according to the ESL executives35

34 For example under the current system a chainwide category manageroperating at the corporate headquarters needs to study and assess numerouspieces of detailed information such as competitorsrsquo price and sale information fromthe last week the past weekrsquos sales at the own chain manufacturersupplier pro-motions wholesale price reductions coop allowances new product offerings shelfspace decisions coordination with newspaper advertising logistics at the ware-houses as well as at each store store differences in terms of customer characteris-tics and competitive environments productshelf selection and layout etc

35 If the supermarket chains indeed restructure the entire price change pro-cess and begin to change prices much more frequently (say two-to-three times aweek) on a regular basis then the shape of this cost function could change in anunpredictable way

V3 Relating Our Findings to the Existing Theoretical Models ofMenu Costs

In order to assess the magnitude of these menu cost guresin the context of the existing theoretical menu cost literatureconsider the following calculation experiments done within theframework of two theoretical menu cost models Blanchard andKiyotaki [1987] study a general equilibrium menu cost modelwith monopolistic competition and with unit elasticity of aggre-gate demand with respect to real money balances According totheir calculations menu costs of the magnitude of 008 percent ofrevenues which they consider ldquovery smallrdquo may be sufcient toprevent adjustment of prices Ball and Romer [1990] conductsimilar calculations in the framework of a model with imperfectcompetition and menu costs They nd that for plausible markupand labor elasticity parameter values menu costs needed to pre-vent price adjustment are 070 percent of revenues which as theysuggest are nonnegligible For smaller menu costs eg 004 per-cent of the revenue which Ball and Romer consider ldquotrivialrdquo im-plausibly large values of markup and labor elasticity parametersare needed to prevent price adjustment to monetary shocks

According to the gures in Table IV the reported menu costto revenues ratio for Chains AndashD averages 070 percent rangingfrom 061 percent to 076 percent These are signicantly largerthan the ldquotrivialrdquo 004 or 008 percent gures mentioned abovesuggesting that the menu cost gures we nd here are nontrivialFurther under the model and parameter values considered byBlanchard and Kiyotaki [1987] the menu cost gures we nd arehigher than the theoretical minimum needed to form a barrier toprice adjustments Under the model and parameter values con-sidered by Ball and Romer [1990] the reported menu costreve-nue ratio for all but one chain reaches or crosses the theoreticalthreshold of 070 needed to form a barrier to price adjustmentsThe existence of numerous unmeasured menu cost componentsdiscussed in subsection III5 also raises the possibility that theactual menu costs incurred by these chains are signicantlyhigher than that threshold This suggests that the menu costs wereport may be large enough to form a barrier to nominal priceadjustments when interpreted in the context of these models

An issue of interest in this literature is time-dependent ver-sus state-dependent pricing rules (see for example Caplin andLeahy [1991]) The evidence from our data set on the timing of

THE MAGNITUDE OF MENU COSTS 819

price changes suggests that the price change decisions in thesesupermarkets have a strong time-dependent price-setting ele-ment36 For example according to Table VI the prices in Chain Aare changed weekly according to the following schedule the pricechanges of general merchandise that is advertised is done Satur-day nights grocery and produce prices are changed Sundaynights the rest of the general merchandise prices are changed onMonday nights and the prices of advertised grocery items arechanged on Tuesday nights Thus as the gures in Table VI indi-cate over 96 percent of the price changes are done during Sundayand Monday nights However this does not imply that state-dependent pricing rules are unimportant Even if price changesacross product categories follow a prescheduled weekly time ta-ble the prices of which products to change is likely to be a state-dependent decision For example it could depend on changes insupply and demand conditions such as competitorsrsquo price changedecisions Indeed Levy Dutta and Bergen [1996] use retailstore-level orange juice price and cost data to demonstrate thatthe extent of price response to cost shocks that is the extent ofprice rigidity may depend on the nature of supply shocks37

We do not want to overstate the usefulness of our data fordirectly addressing the issue of monetary nonneutrality On onehand authors such as Caplin and Spulber [1987] have demon-strated that under certain conditions individual price rigiditymay not be sufcient for aggregate price rigidity but unfortu-nately our data do not speak directly to this issue38 On the otherhand authors such as Akerlof and Yellen [1985] Mankiw [1985]Parkin [1986] and Caplin and Leahy [1997] have shown that even

36 Danziger [1983] Caballero [1989] and Ball and Mankiw [1994] suggestthat time-dependent price adjustment of the type documented here can be optimalif the cost of gathering information about the state exceeds the cost of making theprice adjustment itself

37 We also considered the possibility of convexities in the cost of changingprices Our data do not suggest many convexities since the labor time spent inthe price tag change process the cost of printing and delivering price tags andin-store supervision time do not change with the size of a price change The onlymeasurable component of menu costs that could be convex is the cost of mistakesmade the larger the price change the higher the probability of a customer notic-ing the mistake and the larger the amount required to be refunded as compensa-tion Among the unmeasured components of menu cost the cost of corporatemanagerial time may increase with the size of a price change because larger pricechanges may require more serious consideration

38 Also see Balke and Wynne [1996] and Bryan and Cecchetti [1996] Sincewe do not have measures of how menu costs change over time our data also havelittle to say about time variation in menu costs or about the relationship betweenmenu costs and ination which during the period of the data collection (1991ndash1992) averaged about 3 percent annually

QUARTERLY JOURNAL OF ECONOMICS820

small menu costs can be relevant since they may be sufcient togenerate substantial aggregate nominal rigidity and thus largebusiness cycles Therefore as Blinder [1994] Kashyap [1995]and Slade [1996a] emphasize it is important to search for directevidence that such costs are indeed present at the micro level Bydirectly identifying documenting and measuring the magnitudeof menu costs at the store level we are taking an important stepin that direction

VI CONCLUSION AND FUTURE RESEARCH

Our main contribution is that we provide direct microeco-nomic evidence on the actual magnitude of menu costs for fourlarge U S retail supermarket chains The annual menu costs perstore at these chains average $105887 comprising 070 percentof revenues 352 percent of net prot margins and $052 perprice change on average

Further we provide evidence which suggests that thesemenu costs may be forming a barrier to price changes Specifi-cally we show that (1) supermarket chains not subject to itempricing law change prices two and a half times more frequentlythan the chain that is subject to the law (2) within the chain thatis subject to the item pricing law they change prices over threetimes as frequently for products that are exempt from this lawthan for the products which are subject to this law and (3) wend that these chains do not adjust prices of up to one-third ofthe products for which they face cost increases because of menucost considerations

When we relate these ndings to the existing theoreticalmodels of menu costs we conclude that the magnitude of menucosts we nd is large enough to be capable of having macroeco-nomic signicance Specically when considered in the context ofthe theoretical menu cost models of Blanchard and Kiyotaki[1987] and Ball and Romer [1990] we nd that the menu costgures we report are ldquonontrivialrdquo and their relative magnitudescross the minimum theoretical threshold needed to form a barrierto price adjustments

Despite the high relative magnitude of the marginal cost ofchanging price that we found the data still indicate frequentweekly price changes This is because of the high marginal bene-t of changing price which is due to the erce competition foundin the retail supermarket industry That marginal benets may

THE MAGNITUDE OF MENU COSTS 821

outweigh the marginal costs of changing prices in this industryhowever does not rule out the possibility that menu costs of themagnitude we nd here can create substantial nominal rigidityin other industries or markets In less competitive industries andmarkets menu costs of the type and magnitude we documenthere are likely to have a bigger impact on the frequency of priceadjustment and consequently on the degree of price rigidity

At a minimum the direct dollar measures of menu costs wereport here can be used as a starting point for future research onmeasuring their magnitude in other industries and establish-ments We anticipate that these menu costs will be similar inother markets which rely on posted prices (such as drugstoresdepartment stores etc) because the steps involved in the pricechange process are likely to be similar What may differ are thefrequency of price changes and the labor wage rates at thesestores For example since supermarket chains change thousandsof prices each week the total annual menu costs incurred bythese chains per store are likely to be high in comparison to otherretail formats such as chain drugstores or department storesThere are however a variety of industries for which the stepsinvolved in changing prices would be signicantly different fromthose reported in our study For example business-to-businesssales which often rely on a sales force will require changes in thelist price sheets changes in the instructions to the sales forcewhich may include education and discussion with the salespeoplein the company and so forth These business-to-business pricesalso often have more complex pricing schemes including quantitydiscounts bundling and individually negotiated prices As an-other example the composition of the cost of changing the news-stand prices of magazines [Cecchetti 1986] or the prices ofproducts sold through catalogs [Kashyap 1995] are different frommany of the menu cost components we discuss here Further thending that a centralization of pricing decisions makes the store-level managerial component of menu cost relatively small sug-gests that the managerial menu costs likely are highest insettings where price change decisions are decentralized Thus fu-ture empirical work should look at menu cost and its compositionin a variety of other industries markets and products with bothcentralized as well as decentralized price change decisions in or-der to see whether the magnitude of these costs can be general-ized and benchmarks can be established Further there aretechnological changes taking place in this and other industries

that promise to alter the structure of menu costs which deserveattention At the theoretical level our ndings suggest that it maybe worthwhile to explore models which incorporate the idea ofitem pricing laws as an additional component of menu costs

grocery operating expenses is labor costs [Hoch Dreze andPurk 1994]14

III2 Costs of Printing and Delivering New Price Tags

There are direct costs associated with printing and deliv-ering the price and sign tags The order must be recorded andprocessed at the chain sent to the printer recorded and pro-cessed at the printer printed packaged and then delivered toeach store The cost per tag is usually quite low $0017 per tagat Chain A which includes stock costs of $00118 per tag impres-sion and data center operator costs of $00037 per tag and mailroom handling costs of $00010 per tag There are however manyprice changes undertaken each week In total the costs of print-ing and delivering the price and sign tags range from $3048 to$10018 averaging $6014 per store per year (see Table III)These costs comprise less than 6 percent of the total menu costswe report

III3 Costs of Mistakes Made in the Process of Changing Prices

Despite the labor put into checking to make sure that theprice changes are done correctly there are still many price mis-takes that are not caught until customers discover them through-out the week and these mistakes impose costs on the chainClearly the costs associated with these errors must be consideredwhen deciding whether to change prices or not and therefore area relevant dimension of menu costs These mistakes can occur sooften that they were a feature of a Dateline segment on U Ssupermarket chains [NBC April 1992] and an article in MoneyMagazine [April 1993] Both the Money Magazine article andGoodstein [1994] report that on average 10 percent of the prod-ucts they examined had price mistakes A more recent study bythe Federal Trade Commission [1996] reports a total error rate ofabout 5 percent

The menu costs associated with these mistakes include lost

14 Our measure of labor cost may overstate the true costs of changing pricesif supermarkets hoard labor to save hiring and ring costs However this is notlikely to be the case for several reasons First the labor costs of changing priceswe report are based on actual measurements of the minimum amount of time andlabor required to accomplish the task rather than on the number of employeeshired to change prices at the store Second the adjustment in the amount of laboris usually done through hours worked which makes cost of hiring and ring lessrelevant And third the workers on the oor are routinely moved from task totask according to the need These tasks include stocking cleaning price changingcustomer service etc The workers employed by supermarket chains are alwaysbusy and so the opportunity cost of changing price is not zero Therefore laborhoarding is not likely to be an important factor in our measurements

QUARTERLY JOURNAL OF ECONOMICS806

cashier time to correct the errors scan guarantee refunds andinventory mistakes associated with incorrect price tags15 Lostcashier time is measured here in terms of wage payments Scanguarantee refunds are additional price reductions beyond the er-ror or additional items given away for free because of the mis-take Finally the inventory mistakes costs we report include onlythe cost of stockouts which occur when shelf price is lower thanintended

The mistake costs were available at Chains A C and D andthey range from $19135 to $20692 for an average of $20140 perstore annually (see Table III) These costs are the second largestcomponent of menu costs in our study comprising about 19 per-cent of the total

III4 Costs of In-Store Supervision Time Spent on ImplementingPrice Changes

Managers at the store level spend time overseeing imple-menting and troubleshooting the price change process OnlyChains A and B had a measure of the menu costs associated withthis in-store supervision time and both of these came from a self-reported number of hours spent on changing prices by the manag-ers at these chains The hours spent on changing prices were thesame across the chains approximately ve hours per week Thusthe menu costs for in-store supervision time came to $4241 and$6692 per store annually for Chains A and B respectively (seeTable III) These costs comprise less than 6 percent of the totalmenu costs we report in this paper However notice that thesemeasures do not include the cost of the management time spenton price change decisions made at corporate headquarters whichis discussed next

III5 Components of Menu Costs We Are Unable to Measure inDollar Terms

Our data set does not contain the exact dollar measures ofsome menu cost components One such component is the cost ofcorporate management time spent on price change decisions16 In

15 Other likely costs of price mistakes that we do not consider explicitlybecause we are unable to measure them in dollar terms are legal problems (whenthe scanner price is higher than the shelf price) loss in customer goodwill anddecreased protability (when the scanner price is lower than the shelf price)

16 It has been suggested that the cost of managerial decisions is one of themost important components of menu cost See for example Ball and Mankiw[1994] Kashyap [1995] and Meltzer [1995] Since the ESL system was not de-

THE MAGNITUDE OF MENU COSTS 807

the supermarket chains we study prices are generally set at cor-porate headquarters in a weekly meeting where the manager incharge of setting prices looks at a variety of information including(a) any manufacturer wholesale price changes promotions andother related issues (b) past sales for this product and (c) com-petitorsrsquo prices Based on this information and on discussionswith other managers the price-setting manager decides whetherto change prices and if so by how much

To estimate the magnitude of these managerial componentsof the menu costs consider the following In an average chainthere is at least one executive of merchandising who devotesmost of hisher time to pricing decisions In addition there areup to three senior managers who would deal with pricing andto whom category managers report There are also ten-to-twelvecategory managers who are responsible for setting prices on allthe products within their category An additional two-to-fourpeople spend full time handling the implementation of pricechanges across retail outlets coordinating the printing and deliv-ery of price tags and handling pricing problems in the systemAnother ve-to-seven workers gather the data on competitorsrsquoprices and analyse both the competitorsrsquo data and the storersquos ownscanner data to put it in a form useable by managers makingpricing decisions Thus in total there are about 21ndash27 peopleworking at the corporate headquarters on price change decisionsAssuming $150000 as the average annual salary of the executiveof merchandising and senior managers $100000 for categorymanagers and $50000 for the rest the chainwide managerialcost falls in the neighborhood of $23ndash$29 million a year whichseems a substantial amount However note that these pricing de-cision are made for the entire chain and therefore the costs perstore are signicantly less especially for the larger chains Forexample using $29 million as the upper bound the additionalannual menu cost per store for Chains AndashD which on averageoperate about 400 stores each averages about $7250 which ismuch lower than expected and is due to the centralization of theprice change decisions in the chains we study17

signed to save the costs of corporate headquarter managerial time spent on pricechange decisions the ESL company did not measure this component of menucosts The estimates reported in this section are based on the information receivedfrom the ESL company executives

17 A decentralization of the price change process say by allowing the store-level managers to make price change decisions can change these gures tremen-dously For example consider the following thought experiment conducted using

QUARTERLY JOURNAL OF ECONOMICS808

Our menu cost measures also do not include the cost ofchanging prices of direct store delivery (DSD) products Theseproducts are almost completely handled by manufacturers in-cluding stocking monitoring inventories and setting and chang-ing prices18 We have data on the weekly frequency of pricechanges of DSD products in Chain E In an average week thereare 174 price changes of DSD products which is about 10 percentof the supermarketrsquos total weekly price changes Using the costof changing the price of a regular product $133 (see Section IVfor details) the annual cost of changing prices of the DSD prod-ucts in this chain roughly equals $1203419 Our menu cost mea-sures do not include these gures since we do not have similardata for the other chains20

III6 Total Menu Costs

The total annual menu costs reported for each chain perstore are listed in the last row of Table III As the table indicatesthe menu costs range from $91416 to $114188 for an average of$105887 per store per year21 Note that these menu cost mea-

the average annual per store gures for Chains AndashD Suppose that the supermar-ket chains decentralize the price change process by hiring for each store only one-quarter of the price change managing team while at the same time they com-pletely eliminate the corporate level team The resulting annual menu cost perstore would be $830887 ( 5 $105887 1 $725000) which would dwarf any of themeasurable menu cost gures we report in this study Even if the average storeonly hired just the merchandising manager at the annual cost of $150000 itwould still incur annual managerial cost of about $255887 ( 5 $105887 1$150000) In other words such a trivial decentralization would double the store-level menu costs This would indeed make the cost of price change decisions themost important component of menu cost

18 DSD products usually are high-volume fast-moving or perishable prod-ucts such as milk soda eggs bread dairy snacks etc In the chains we studyabout 10ndash20 percent of the products are of a DSD type but that share may reachas much as 40 percent of the products carried [Direct Store Delivery Work Groupet al 1995]

19 The process of changing prices of DSD and of regular products is similarBut with DSD products there are additional costs of the time spent on driving tothe store parking and setting up the price change process at each store

20 Our measures of menu cost also do not incorporate the cost of informingconsumers about price changes which can take a variety of forms such as newspa-per ads and inserts TV and radio ads in-store promotion signs etc Finally wehave no data on lost customer goodwill and damaged reputation caused by dis-crepancies between price tag and cash register [Okun 1981 Carlton and Perloff1994 Haddock and McChesney 1994]

21 The variation in the menu costs across the chains is mostly due to wagerate and labor-efciency variations Also note that since the supermarket chainsin our sample are similar in the size of their stores carry similar sets of productsand follow similar processes of price change and price change decisions it is rea-sonable to believe that the chains incur similar types of costs Therefore as notedunderneath Table III these menu cost measures are computed by replacing theunreported gures by the averages of the available values from the other chains

THE MAGNITUDE OF MENU COSTS 809

sures include only the components we could accurately measurein dollar terms which are discussed in subsections III1ndashIII4

IV ITEM PRICING LAWS AND MENU COSTS

In this section we provide evidence on the menu costs for anadditional chain (Chain E) which unlike the other four chainsoperates in a state with an item pricing law The most importantaspect of item pricing laws is that they require a price tag on eachindividual item sold not just on the shelf which is what the otherfour chains in our sample do For example the item pricing lawin Connecticut requires that the grocers ldquoshall mark or cause tobe marked each consumer commodity which bears a UniversalProduct Code with its retail pricerdquo 22 From a menu cost perspec-tive the requirement of posting prices on every item (in additionto the shelf price tag) introduces additional costs in the processof changing prices

Although most of the steps involved in changing prices arethe same for both types of chains stores that are subject to itempricing laws have to undertake additional steps to obey this law23

The labor cost component of menu costs in Chain E totals $75127a year of which $49710 is the cost of the labor time spent onchanging the prices of individual items $3234 is the cost of thelabor time spent on shelf tag replacements and $22183 is thecost of the labor time spent on sign changes (see Table III)24 Anadditional $44168 is spent annually putting prices on new itemsas they are brought to the shelves Although we do not includethis last gure in our menu cost measures because we do not haveinformation on how much of it is due to price change activity andhow much due to just pricingmdashthese costs are clearly a directconsequence of the item pricing law The printing and deliverycost of price tags and price signs are $7644 and the mistake

22 Public Act No 75ndash391 An Act Concerning Pricing of Consumer Merchan-dise [Public Acts of the State of Connecticut 1975 Vol 1 p 390]

23 These steps which are in addition to the regular steps undertaken toreplace price tags on the shelves include (1) obtaining item price tags (2) settingup workstations (3) locating the product (4) removing an item from the shelf (5)removing old price tag (6) setting marking gun (7) applying new price tag and(8) returning the item back to the shelf

24 Since we do not have a measure of the cost of labor time spent on signchanges and the cost of in-store managerial supervision time for this chain weuse the average of the chains that report them (A and D) Note also that thehourly wage rate of $907 paid by Chain E is lower than the hourly wage of about$1400ndash$2000 paid by Chains AndashD

QUARTERLY JOURNAL OF ECONOMICS810

25 Further note that the chains with smaller menu costs are likely tochange their prices more frequently which suggests that the gures of the totalannual menu costs understate the differences between Chain E and the otherchains Indeed despite the large difference in the menu cost per price change thetotal annual menu costs per store for Chain E ($109036) are more comparable tothose of Chains AndashD ($105887)

26 In calculations that follow we use industry averages because (1) thechains did not share this proprietary information with us and (2) we were re-quired to keep the identity of these chains condential as some of these numbersare detailed enough to enable some readers to identify the chains under study

costs are $20799 These gures along with the amount of $5466for the cost of in-store managerial supervision time yield totalannual menu costs of $109036 per store

Although the magnitude of the total annual menu costs seemsimilar to the other four chains note that the average weeklyfrequency of price changes in Chain E is only 1578 which is only403 ( 5 15783916) percent of the price changes made by theother four chains Thus the average menu cost per price changefor Chain E is $133 (see Table IV last row) In contrast the corre-sponding gures for Chains AndashD average $052 Hence the menucosts per price change incurred by the supermarket chain facingitem pricing laws are more than two and a half times the amountincurred by chains that are not subject to this law25 Overallthese ndings suggest that legal restrictions of the type of itempricing laws can have a signicant impact on the menu costs in-curred by sellers

V SIGNIFICANCE OF THE MENU COSTS

The next natural question to ask is how important are thesecosts To address this question we (1) provide several relativemeasures of the menu costs (2) discuss the effect of the menucosts on supermarketsrsquo price change activity and (3) discuss mac-roeconomic implications by relating our ndings to the existingtheoretical models of menu costs In each case we provide addi-tional evidence to help assess the importance of these menu costs

V1 Relative Measures of the Menu Costs

In order to assess the relative magnitude of the menu costsreported in Section IV we now present the menu cost gures rela-tive to the average store-level revenues and net prot margins26

In addition we present the menu cost gures per price changeThe annual average revenues of a large U S supermarket

chain of the type and size included in our sample is $15052716

per store27 According to the second row of Table IV the ratio ofmenu costs to revenues for Chains AndashD ranges between 061ndash076percent averaging 070 percent28 We relate the size of thesegures to the existing theoretical menu cost models in sub-section V3

Net prot margin which measures the revenues minus allcosts is approximately 1ndash3 percent of revenues for these chains[Montgomery 1994] so we use 2 percent as a working averageThe reason for the low prot rate in this industry is the intensecompetition [Calatone et al 1989] especially at the regional level[Chevalier 1995] which has been increasing since the early 1990s[Progressive Grocer November 1992 p 50] It follows that theaverage store protability for these chains equals $301054 peryear Therefore the ratio of total menu cost to net margin forChains AndashD ranges between 304ndash379 percent for an average of352 percent Thus the menu costs we report in this study repre-sent a signicant share of supermarketsrsquo prots

Another way to look at the menu cost gures we report is toexpress them relative to the frequency of price changes In thelast row of Table IV we present the menu cost gures per pricechange for each chain As the table indicates the cost of changinga price in Chains AndashD ranges between $046ndash$068 for an averageof $052 For Chain E the gure is substantially larger $133 perprice change29 These gures are lower than the estimated cost of

27 This is the average of two different estimates $12945432 and$17160000 The source of the rst gure is internal record of a supermarketchain of the type and size studied here The second gure comes from Supermar-ket Business [1993 p 52]

28 We also measured the menu costs in terms of controllable operating ex-penses (which are the portion of costs that the retailer has direct control over andtherefore are often the costs that the retailer is most focused on managing) andgross margins (which measure the supermarket revenues minus direct cost of theproducts it sells) We nd that the menu costs comprise 313 percent of controlla-ble operating expenses and 281 percent of gross margins at these chains on aver-age Finally if we measure the menu costs relative to the number of productscarried per store (about 25000) then we nd that the menu costs per productaverage $423 for Chains AndashD See Table IV and its footnotes for details

29 We can also try to express the menu cost gures relative to the numberof individual items sold by these chains each year (Note the difference betweennumber of products carried and number of items sold As an example a TartarControl Crest 8oz would be considered a product carried and 300 units of themsold per year would be considered number of items sold) Using $170 as the aver-age price of all the products sold we nd that the menu cost per item sold for thefour chains is in the range of $00103ndash$00129 for an average of $00119 (see TableIV second to last row) To see the relative magnitude of these gures note thataccording to Berkowitz Kerin and Rudelius [1986 p 319] the goal of the super-market chains of the type we study ldquo is to make 1 penny of prot on each dollarof salesrdquo Thus menu cost per item sold when adjusted for the average price

THE MAGNITUDE OF MENU COSTS 813

$200ndash$300 per price change reported by Slade [1996a] Thereare several possible reasons for this (1) our menu cost gures arebased on actual measurements of the resources that go into theprice change process whereas she estimates menu costs econo-metrically as model coefcients using a mix of store-level priceand aggregate cost data (2) we cover 25000 products that thesupermarkets carry rather than a single product category (3) ourmenu cost gures do not include all components of menu costsand (4) there could be differences in wage rates that may be im-portant given the signicance of the labor cost component inmenu costs

V2 The Effect of Menu Costs on the Price Change Activity of theSupermarkets

In this section we present evidence which suggests that thesemenu costs may be forming a barrier to price change activity Tobegin with consider the effect of the item pricing law on the pricechange activity of Chain E The data on the weekly frequency ofprice changes in each chain are displayed in the last two rows ofTable I According to these gures the average weekly frequencyof price changes in Chain E is only 1578 Thus on average ChainE changes the prices of only 631 percent of its products eachweek In contrast the average weekly frequency of price changesat Chains AndashD ranges from 3223 to 4316 for the four-chain aver-age of 3916 price changes weekly So Chains AndashD change priceson 1289 to 1726 percent of their products each week yielding afour-chain average of 1566 percent Thus Chain E which facesthe item pricing law changes prices only about one-third timesas frequently as do Chains AndashD30

Moreover within Chain E there are 400 products that areexempt from the item pricing law and thereby face lower menucosts We nd that there are an average of 83 weekly pricechanges for these products yielding 21 percent of these productschanging prices So within Chain E they change prices over threetimes as frequently for products with lower menu costs than for

roughly equals one-half of their target net prot per item which seemssubstantial

30 However note that our comparison of the two types of chains may not becompletely ceteris paribus because these stores are located in different states andtherefore there may be other chain-specic factors (in addition to item pricinglaws) that distinguish these stores We do not have any specic information onthese differences We do know however that the stores in these chains are similarin size and carry similar sets of products

QUARTERLY JOURNAL OF ECONOMICS814

the products with higher menu costs Note that this nding is onthe price change activity within the same chain offering almost anatural experiment on the impact of menu costs on the chainrsquospricing behavior Hence we provide evidence both across chainsas well as across products within a chain that as the costs ofchanging price go up the frequency of price changes goes downThus the menu costs we nd are signicant enough to affect thechainrsquos price change practice

We also have additional evidence from Chains A B and Dabout these menu costs being a barrier to certain price changesand it is summarized in Table V According to the Price Manage-ment Department of Chain A the chain experiences cost in-creases on 860 products in an average week to which it wouldlike to react with a price increase31 However on average 22 per-cent of these price increases are not implemented immediatelybecause the cost of changing prices for these products is too highto make it economically worthwhile Figures of the same magni-tude were reported by other chains For example Chain D experi-ences cost increases for 961 products in an average week Out ofthese the chain adjusts prices of only 633 products The re-maining 34 percent of the prices are left unadjusted because ofthe menu costs Similarly Chain B nds it economically ineffi-cient to adjust prices of 508 ie 30 percent of its products eachweek because of menu costs This provides additional evidencethat the menu costs incurred by these chains are preventing priceadjustments to some costs changes leading to price rigidities ofthe products involved32 Note that although we do not have simi-lar data for Chain E we would expect signicantly lower num-bers on this measure at that chain These gures also suggest anupper bound on the benet of complete price exibility under thecurrent pricing practice of weekly price adjustments Howeverif new technologies (eg ESL systems) and new pricing prac-tices (eg a decentralization of the price change decisions) are

31 Our data contain information only on the frequency of cost increasesAlthough it is more than likely that the supermarkets are experiencing cost de-creases as well our data set contained no information on such decreases

32 Menu costs may even be playing a role in the observed movement towardpricing strategies that rely on fewer price changes such as EDLP [Blattberg andNeslin 1989 Lattin and Ortmeyer 1991 Marketing News April 13 1992 p 8]According to Progressive Grocer [November 1992 p 50] ldquoA growing number ofoperators say they have switched from high-low pricing [to EDLP] They cite theinefciencies of making frequent price changes rdquo Similarly Hoch Dreze andPurk [1994 p 16] state that EDLP lowers operating costs by lowering ldquo in-store labor costs because of less frequent changeovers in special displaysrdquo

adopted allowing a fundamental change in the way the pricingmechanism is currently set the managers could consider morefrequent price change activity (eg multiple times each week) asmenu costs go down

In this paper we measure the menu costs at the chainsrsquo cur-rent level of price change activity It may be worthwhile to specu-late on the shape of the cost function relating menu costs to thefrequency of price changes by assessing how these costs wouldchange if the price change activity were to increase or to decreaseIt seems likely that many of the costs we report in this paper will(approximately) change linearly with additional price changeswithin the current range of price changes the chains are under-taking (plus or minus perhaps a thousand per week) For ex-ample the labor costs associated with changing a shelf price tagcosts of verifying price changes and the costs of mistakes oc-curring during this process all increase linearly with the fre-quency of price changes This is because most of the time-consuming steps involved in the price change process must berepeated each time an additional shelf price tag is changed (seeTable II) Further we were unable to nd many tasks that gener-ated signicant returns to scale It is unclear what cost savingsare available if the price change activity drops substantially be-

QUARTERLY JOURNAL OF ECONOMICS816

low the levels it is at now Clearly if price changes were nearzero or done less frequently than weekly (say monthly) therecould be major differences in these costs

What is less clear is how these costs would change at moreextreme levels of price change activity With less frequent pricechanges the menu costs could probably be reduced signicantlyalthough the cost of deciding what prices to set initially and thecost of putting the initial shelf price tags would still remain as alower bound of the menu cost However for achieving more priceexibility by changing prices more frequently (ie multiple timeseach week) substantial changes must be undertaken At presentthe supermarket chains are set up to make the majority of theirprice changes on a weekly basis with the appropriate systems inplace to make this process most efcient For example in orderto save costs and to have higher quality price tags (eg withcolor more details greater clarity glossy etc) the chains oftensend new price tag requests to a printing shop which takes threedays to print and deliver the labels to each store Then giventhe large number of price changes taking place and the goals ofminimizing customer disruptions and labor costs (such as over-time pay) and coordinating with advertised price promotions theprices are changed in the store over a two-to-three-day period (seeTable VI) The combination of these schedule and built-in lags isacceptable under the current practice of changing prices weeklybut would have to be adjusted dramatically to allow for signifi-cantly more frequent price changes on a regular basis

Perhaps even more imposing are the costs of changing themanagerial costs associated with the current weekly system ofprice changes The process of pricing at this organizational levelis not a self-contained activity taking place in isolation from otheroperations of the supermarket management Rather it is a partof a larger system of business decisions and operations The cur-rent process of operations (such as data collection and theiranalysis management meetings coordination of the decisionsacross functional areas etc) is set up to function on a weeklybasis33 Further these management accounting and logisticssystems are currently built around a tremendous amount of in-

33 For example the data are analyzed and presented to managers on Mon-day and Tuesday with meetings set for Thursday and Friday to make pricingdecisions for the next week in coordination with all other business functions ofthe chain

35 If the supermarket chains indeed restructure the entire price change pro-cess and begin to change prices much more frequently (say two-to-three times aweek) on a regular basis then the shape of this cost function could change in anunpredictable way

V3 Relating Our Findings to the Existing Theoretical Models ofMenu Costs

In order to assess the magnitude of these menu cost guresin the context of the existing theoretical menu cost literatureconsider the following calculation experiments done within theframework of two theoretical menu cost models Blanchard andKiyotaki [1987] study a general equilibrium menu cost modelwith monopolistic competition and with unit elasticity of aggre-gate demand with respect to real money balances According totheir calculations menu costs of the magnitude of 008 percent ofrevenues which they consider ldquovery smallrdquo may be sufcient toprevent adjustment of prices Ball and Romer [1990] conductsimilar calculations in the framework of a model with imperfectcompetition and menu costs They nd that for plausible markupand labor elasticity parameter values menu costs needed to pre-vent price adjustment are 070 percent of revenues which as theysuggest are nonnegligible For smaller menu costs eg 004 per-cent of the revenue which Ball and Romer consider ldquotrivialrdquo im-plausibly large values of markup and labor elasticity parametersare needed to prevent price adjustment to monetary shocks

According to the gures in Table IV the reported menu costto revenues ratio for Chains AndashD averages 070 percent rangingfrom 061 percent to 076 percent These are signicantly largerthan the ldquotrivialrdquo 004 or 008 percent gures mentioned abovesuggesting that the menu cost gures we nd here are nontrivialFurther under the model and parameter values considered byBlanchard and Kiyotaki [1987] the menu cost gures we nd arehigher than the theoretical minimum needed to form a barrier toprice adjustments Under the model and parameter values con-sidered by Ball and Romer [1990] the reported menu costreve-nue ratio for all but one chain reaches or crosses the theoreticalthreshold of 070 needed to form a barrier to price adjustmentsThe existence of numerous unmeasured menu cost componentsdiscussed in subsection III5 also raises the possibility that theactual menu costs incurred by these chains are signicantlyhigher than that threshold This suggests that the menu costs wereport may be large enough to form a barrier to nominal priceadjustments when interpreted in the context of these models

An issue of interest in this literature is time-dependent ver-sus state-dependent pricing rules (see for example Caplin andLeahy [1991]) The evidence from our data set on the timing of

THE MAGNITUDE OF MENU COSTS 819

price changes suggests that the price change decisions in thesesupermarkets have a strong time-dependent price-setting ele-ment36 For example according to Table VI the prices in Chain Aare changed weekly according to the following schedule the pricechanges of general merchandise that is advertised is done Satur-day nights grocery and produce prices are changed Sundaynights the rest of the general merchandise prices are changed onMonday nights and the prices of advertised grocery items arechanged on Tuesday nights Thus as the gures in Table VI indi-cate over 96 percent of the price changes are done during Sundayand Monday nights However this does not imply that state-dependent pricing rules are unimportant Even if price changesacross product categories follow a prescheduled weekly time ta-ble the prices of which products to change is likely to be a state-dependent decision For example it could depend on changes insupply and demand conditions such as competitorsrsquo price changedecisions Indeed Levy Dutta and Bergen [1996] use retailstore-level orange juice price and cost data to demonstrate thatthe extent of price response to cost shocks that is the extent ofprice rigidity may depend on the nature of supply shocks37

We do not want to overstate the usefulness of our data fordirectly addressing the issue of monetary nonneutrality On onehand authors such as Caplin and Spulber [1987] have demon-strated that under certain conditions individual price rigiditymay not be sufcient for aggregate price rigidity but unfortu-nately our data do not speak directly to this issue38 On the otherhand authors such as Akerlof and Yellen [1985] Mankiw [1985]Parkin [1986] and Caplin and Leahy [1997] have shown that even

36 Danziger [1983] Caballero [1989] and Ball and Mankiw [1994] suggestthat time-dependent price adjustment of the type documented here can be optimalif the cost of gathering information about the state exceeds the cost of making theprice adjustment itself

37 We also considered the possibility of convexities in the cost of changingprices Our data do not suggest many convexities since the labor time spent inthe price tag change process the cost of printing and delivering price tags andin-store supervision time do not change with the size of a price change The onlymeasurable component of menu costs that could be convex is the cost of mistakesmade the larger the price change the higher the probability of a customer notic-ing the mistake and the larger the amount required to be refunded as compensa-tion Among the unmeasured components of menu cost the cost of corporatemanagerial time may increase with the size of a price change because larger pricechanges may require more serious consideration

38 Also see Balke and Wynne [1996] and Bryan and Cecchetti [1996] Sincewe do not have measures of how menu costs change over time our data also havelittle to say about time variation in menu costs or about the relationship betweenmenu costs and ination which during the period of the data collection (1991ndash1992) averaged about 3 percent annually

QUARTERLY JOURNAL OF ECONOMICS820

small menu costs can be relevant since they may be sufcient togenerate substantial aggregate nominal rigidity and thus largebusiness cycles Therefore as Blinder [1994] Kashyap [1995]and Slade [1996a] emphasize it is important to search for directevidence that such costs are indeed present at the micro level Bydirectly identifying documenting and measuring the magnitudeof menu costs at the store level we are taking an important stepin that direction

VI CONCLUSION AND FUTURE RESEARCH

Our main contribution is that we provide direct microeco-nomic evidence on the actual magnitude of menu costs for fourlarge U S retail supermarket chains The annual menu costs perstore at these chains average $105887 comprising 070 percentof revenues 352 percent of net prot margins and $052 perprice change on average

Further we provide evidence which suggests that thesemenu costs may be forming a barrier to price changes Specifi-cally we show that (1) supermarket chains not subject to itempricing law change prices two and a half times more frequentlythan the chain that is subject to the law (2) within the chain thatis subject to the item pricing law they change prices over threetimes as frequently for products that are exempt from this lawthan for the products which are subject to this law and (3) wend that these chains do not adjust prices of up to one-third ofthe products for which they face cost increases because of menucost considerations

When we relate these ndings to the existing theoreticalmodels of menu costs we conclude that the magnitude of menucosts we nd is large enough to be capable of having macroeco-nomic signicance Specically when considered in the context ofthe theoretical menu cost models of Blanchard and Kiyotaki[1987] and Ball and Romer [1990] we nd that the menu costgures we report are ldquonontrivialrdquo and their relative magnitudescross the minimum theoretical threshold needed to form a barrierto price adjustments

Despite the high relative magnitude of the marginal cost ofchanging price that we found the data still indicate frequentweekly price changes This is because of the high marginal bene-t of changing price which is due to the erce competition foundin the retail supermarket industry That marginal benets may

THE MAGNITUDE OF MENU COSTS 821

outweigh the marginal costs of changing prices in this industryhowever does not rule out the possibility that menu costs of themagnitude we nd here can create substantial nominal rigidityin other industries or markets In less competitive industries andmarkets menu costs of the type and magnitude we documenthere are likely to have a bigger impact on the frequency of priceadjustment and consequently on the degree of price rigidity

At a minimum the direct dollar measures of menu costs wereport here can be used as a starting point for future research onmeasuring their magnitude in other industries and establish-ments We anticipate that these menu costs will be similar inother markets which rely on posted prices (such as drugstoresdepartment stores etc) because the steps involved in the pricechange process are likely to be similar What may differ are thefrequency of price changes and the labor wage rates at thesestores For example since supermarket chains change thousandsof prices each week the total annual menu costs incurred bythese chains per store are likely to be high in comparison to otherretail formats such as chain drugstores or department storesThere are however a variety of industries for which the stepsinvolved in changing prices would be signicantly different fromthose reported in our study For example business-to-businesssales which often rely on a sales force will require changes in thelist price sheets changes in the instructions to the sales forcewhich may include education and discussion with the salespeoplein the company and so forth These business-to-business pricesalso often have more complex pricing schemes including quantitydiscounts bundling and individually negotiated prices As an-other example the composition of the cost of changing the news-stand prices of magazines [Cecchetti 1986] or the prices ofproducts sold through catalogs [Kashyap 1995] are different frommany of the menu cost components we discuss here Further thending that a centralization of pricing decisions makes the store-level managerial component of menu cost relatively small sug-gests that the managerial menu costs likely are highest insettings where price change decisions are decentralized Thus fu-ture empirical work should look at menu cost and its compositionin a variety of other industries markets and products with bothcentralized as well as decentralized price change decisions in or-der to see whether the magnitude of these costs can be general-ized and benchmarks can be established Further there aretechnological changes taking place in this and other industries

that promise to alter the structure of menu costs which deserveattention At the theoretical level our ndings suggest that it maybe worthwhile to explore models which incorporate the idea ofitem pricing laws as an additional component of menu costs

III2 Costs of Printing and Delivering New Price Tags

There are direct costs associated with printing and deliv-ering the price and sign tags The order must be recorded andprocessed at the chain sent to the printer recorded and pro-cessed at the printer printed packaged and then delivered toeach store The cost per tag is usually quite low $0017 per tagat Chain A which includes stock costs of $00118 per tag impres-sion and data center operator costs of $00037 per tag and mailroom handling costs of $00010 per tag There are however manyprice changes undertaken each week In total the costs of print-ing and delivering the price and sign tags range from $3048 to$10018 averaging $6014 per store per year (see Table III)These costs comprise less than 6 percent of the total menu costswe report

III3 Costs of Mistakes Made in the Process of Changing Prices

Despite the labor put into checking to make sure that theprice changes are done correctly there are still many price mis-takes that are not caught until customers discover them through-out the week and these mistakes impose costs on the chainClearly the costs associated with these errors must be consideredwhen deciding whether to change prices or not and therefore area relevant dimension of menu costs These mistakes can occur sooften that they were a feature of a Dateline segment on U Ssupermarket chains [NBC April 1992] and an article in MoneyMagazine [April 1993] Both the Money Magazine article andGoodstein [1994] report that on average 10 percent of the prod-ucts they examined had price mistakes A more recent study bythe Federal Trade Commission [1996] reports a total error rate ofabout 5 percent

The menu costs associated with these mistakes include lost

14 Our measure of labor cost may overstate the true costs of changing pricesif supermarkets hoard labor to save hiring and ring costs However this is notlikely to be the case for several reasons First the labor costs of changing priceswe report are based on actual measurements of the minimum amount of time andlabor required to accomplish the task rather than on the number of employeeshired to change prices at the store Second the adjustment in the amount of laboris usually done through hours worked which makes cost of hiring and ring lessrelevant And third the workers on the oor are routinely moved from task totask according to the need These tasks include stocking cleaning price changingcustomer service etc The workers employed by supermarket chains are alwaysbusy and so the opportunity cost of changing price is not zero Therefore laborhoarding is not likely to be an important factor in our measurements

cashier time to correct the errors scan guarantee refunds andinventory mistakes associated with incorrect price tags15 Lostcashier time is measured here in terms of wage payments Scanguarantee refunds are additional price reductions beyond the er-ror or additional items given away for free because of the mis-take Finally the inventory mistakes costs we report include onlythe cost of stockouts which occur when shelf price is lower thanintended

The mistake costs were available at Chains A C and D andthey range from $19135 to $20692 for an average of $20140 perstore annually (see Table III) These costs are the second largestcomponent of menu costs in our study comprising about 19 per-cent of the total

III4 Costs of In-Store Supervision Time Spent on ImplementingPrice Changes

Managers at the store level spend time overseeing imple-menting and troubleshooting the price change process OnlyChains A and B had a measure of the menu costs associated withthis in-store supervision time and both of these came from a self-reported number of hours spent on changing prices by the manag-ers at these chains The hours spent on changing prices were thesame across the chains approximately ve hours per week Thusthe menu costs for in-store supervision time came to $4241 and$6692 per store annually for Chains A and B respectively (seeTable III) These costs comprise less than 6 percent of the totalmenu costs we report in this paper However notice that thesemeasures do not include the cost of the management time spenton price change decisions made at corporate headquarters whichis discussed next

III5 Components of Menu Costs We Are Unable to Measure inDollar Terms

Our data set does not contain the exact dollar measures ofsome menu cost components One such component is the cost ofcorporate management time spent on price change decisions16 In

15 Other likely costs of price mistakes that we do not consider explicitlybecause we are unable to measure them in dollar terms are legal problems (whenthe scanner price is higher than the shelf price) loss in customer goodwill anddecreased protability (when the scanner price is lower than the shelf price)

16 It has been suggested that the cost of managerial decisions is one of themost important components of menu cost See for example Ball and Mankiw[1994] Kashyap [1995] and Meltzer [1995] Since the ESL system was not de-

THE MAGNITUDE OF MENU COSTS 807

the supermarket chains we study prices are generally set at cor-porate headquarters in a weekly meeting where the manager incharge of setting prices looks at a variety of information including(a) any manufacturer wholesale price changes promotions andother related issues (b) past sales for this product and (c) com-petitorsrsquo prices Based on this information and on discussionswith other managers the price-setting manager decides whetherto change prices and if so by how much

To estimate the magnitude of these managerial componentsof the menu costs consider the following In an average chainthere is at least one executive of merchandising who devotesmost of hisher time to pricing decisions In addition there areup to three senior managers who would deal with pricing andto whom category managers report There are also ten-to-twelvecategory managers who are responsible for setting prices on allthe products within their category An additional two-to-fourpeople spend full time handling the implementation of pricechanges across retail outlets coordinating the printing and deliv-ery of price tags and handling pricing problems in the systemAnother ve-to-seven workers gather the data on competitorsrsquoprices and analyse both the competitorsrsquo data and the storersquos ownscanner data to put it in a form useable by managers makingpricing decisions Thus in total there are about 21ndash27 peopleworking at the corporate headquarters on price change decisionsAssuming $150000 as the average annual salary of the executiveof merchandising and senior managers $100000 for categorymanagers and $50000 for the rest the chainwide managerialcost falls in the neighborhood of $23ndash$29 million a year whichseems a substantial amount However note that these pricing de-cision are made for the entire chain and therefore the costs perstore are signicantly less especially for the larger chains Forexample using $29 million as the upper bound the additionalannual menu cost per store for Chains AndashD which on averageoperate about 400 stores each averages about $7250 which ismuch lower than expected and is due to the centralization of theprice change decisions in the chains we study17

signed to save the costs of corporate headquarter managerial time spent on pricechange decisions the ESL company did not measure this component of menucosts The estimates reported in this section are based on the information receivedfrom the ESL company executives

17 A decentralization of the price change process say by allowing the store-level managers to make price change decisions can change these gures tremen-dously For example consider the following thought experiment conducted using

QUARTERLY JOURNAL OF ECONOMICS808

Our menu cost measures also do not include the cost ofchanging prices of direct store delivery (DSD) products Theseproducts are almost completely handled by manufacturers in-cluding stocking monitoring inventories and setting and chang-ing prices18 We have data on the weekly frequency of pricechanges of DSD products in Chain E In an average week thereare 174 price changes of DSD products which is about 10 percentof the supermarketrsquos total weekly price changes Using the costof changing the price of a regular product $133 (see Section IVfor details) the annual cost of changing prices of the DSD prod-ucts in this chain roughly equals $1203419 Our menu cost mea-sures do not include these gures since we do not have similardata for the other chains20

III6 Total Menu Costs

The total annual menu costs reported for each chain perstore are listed in the last row of Table III As the table indicatesthe menu costs range from $91416 to $114188 for an average of$105887 per store per year21 Note that these menu cost mea-

the average annual per store gures for Chains AndashD Suppose that the supermar-ket chains decentralize the price change process by hiring for each store only one-quarter of the price change managing team while at the same time they com-pletely eliminate the corporate level team The resulting annual menu cost perstore would be $830887 ( 5 $105887 1 $725000) which would dwarf any of themeasurable menu cost gures we report in this study Even if the average storeonly hired just the merchandising manager at the annual cost of $150000 itwould still incur annual managerial cost of about $255887 ( 5 $105887 1$150000) In other words such a trivial decentralization would double the store-level menu costs This would indeed make the cost of price change decisions themost important component of menu cost

18 DSD products usually are high-volume fast-moving or perishable prod-ucts such as milk soda eggs bread dairy snacks etc In the chains we studyabout 10ndash20 percent of the products are of a DSD type but that share may reachas much as 40 percent of the products carried [Direct Store Delivery Work Groupet al 1995]

19 The process of changing prices of DSD and of regular products is similarBut with DSD products there are additional costs of the time spent on driving tothe store parking and setting up the price change process at each store

20 Our measures of menu cost also do not incorporate the cost of informingconsumers about price changes which can take a variety of forms such as newspa-per ads and inserts TV and radio ads in-store promotion signs etc Finally wehave no data on lost customer goodwill and damaged reputation caused by dis-crepancies between price tag and cash register [Okun 1981 Carlton and Perloff1994 Haddock and McChesney 1994]

21 The variation in the menu costs across the chains is mostly due to wagerate and labor-efciency variations Also note that since the supermarket chainsin our sample are similar in the size of their stores carry similar sets of productsand follow similar processes of price change and price change decisions it is rea-sonable to believe that the chains incur similar types of costs Therefore as notedunderneath Table III these menu cost measures are computed by replacing theunreported gures by the averages of the available values from the other chains

THE MAGNITUDE OF MENU COSTS 809

sures include only the components we could accurately measurein dollar terms which are discussed in subsections III1ndashIII4

IV ITEM PRICING LAWS AND MENU COSTS

In this section we provide evidence on the menu costs for anadditional chain (Chain E) which unlike the other four chainsoperates in a state with an item pricing law The most importantaspect of item pricing laws is that they require a price tag on eachindividual item sold not just on the shelf which is what the otherfour chains in our sample do For example the item pricing lawin Connecticut requires that the grocers ldquoshall mark or cause tobe marked each consumer commodity which bears a UniversalProduct Code with its retail pricerdquo 22 From a menu cost perspec-tive the requirement of posting prices on every item (in additionto the shelf price tag) introduces additional costs in the processof changing prices

Although most of the steps involved in changing prices arethe same for both types of chains stores that are subject to itempricing laws have to undertake additional steps to obey this law23

The labor cost component of menu costs in Chain E totals $75127a year of which $49710 is the cost of the labor time spent onchanging the prices of individual items $3234 is the cost of thelabor time spent on shelf tag replacements and $22183 is thecost of the labor time spent on sign changes (see Table III)24 Anadditional $44168 is spent annually putting prices on new itemsas they are brought to the shelves Although we do not includethis last gure in our menu cost measures because we do not haveinformation on how much of it is due to price change activity andhow much due to just pricingmdashthese costs are clearly a directconsequence of the item pricing law The printing and deliverycost of price tags and price signs are $7644 and the mistake

22 Public Act No 75ndash391 An Act Concerning Pricing of Consumer Merchan-dise [Public Acts of the State of Connecticut 1975 Vol 1 p 390]

23 These steps which are in addition to the regular steps undertaken toreplace price tags on the shelves include (1) obtaining item price tags (2) settingup workstations (3) locating the product (4) removing an item from the shelf (5)removing old price tag (6) setting marking gun (7) applying new price tag and(8) returning the item back to the shelf

24 Since we do not have a measure of the cost of labor time spent on signchanges and the cost of in-store managerial supervision time for this chain weuse the average of the chains that report them (A and D) Note also that thehourly wage rate of $907 paid by Chain E is lower than the hourly wage of about$1400ndash$2000 paid by Chains AndashD

25 Further note that the chains with smaller menu costs are likely tochange their prices more frequently which suggests that the gures of the totalannual menu costs understate the differences between Chain E and the otherchains Indeed despite the large difference in the menu cost per price change thetotal annual menu costs per store for Chain E ($109036) are more comparable tothose of Chains AndashD ($105887)

26 In calculations that follow we use industry averages because (1) thechains did not share this proprietary information with us and (2) we were re-quired to keep the identity of these chains condential as some of these numbersare detailed enough to enable some readers to identify the chains under study

costs are $20799 These gures along with the amount of $5466for the cost of in-store managerial supervision time yield totalannual menu costs of $109036 per store

Although the magnitude of the total annual menu costs seemsimilar to the other four chains note that the average weeklyfrequency of price changes in Chain E is only 1578 which is only403 ( 5 15783916) percent of the price changes made by theother four chains Thus the average menu cost per price changefor Chain E is $133 (see Table IV last row) In contrast the corre-sponding gures for Chains AndashD average $052 Hence the menucosts per price change incurred by the supermarket chain facingitem pricing laws are more than two and a half times the amountincurred by chains that are not subject to this law25 Overallthese ndings suggest that legal restrictions of the type of itempricing laws can have a signicant impact on the menu costs in-curred by sellers

V SIGNIFICANCE OF THE MENU COSTS

The next natural question to ask is how important are thesecosts To address this question we (1) provide several relativemeasures of the menu costs (2) discuss the effect of the menucosts on supermarketsrsquo price change activity and (3) discuss mac-roeconomic implications by relating our ndings to the existingtheoretical models of menu costs In each case we provide addi-tional evidence to help assess the importance of these menu costs

V1 Relative Measures of the Menu Costs

In order to assess the relative magnitude of the menu costsreported in Section IV we now present the menu cost gures rela-tive to the average store-level revenues and net prot margins26

In addition we present the menu cost gures per price changeThe annual average revenues of a large U S supermarket

chain of the type and size included in our sample is $15052716

per store27 According to the second row of Table IV the ratio ofmenu costs to revenues for Chains AndashD ranges between 061ndash076percent averaging 070 percent28 We relate the size of thesegures to the existing theoretical menu cost models in sub-section V3

Net prot margin which measures the revenues minus allcosts is approximately 1ndash3 percent of revenues for these chains[Montgomery 1994] so we use 2 percent as a working averageThe reason for the low prot rate in this industry is the intensecompetition [Calatone et al 1989] especially at the regional level[Chevalier 1995] which has been increasing since the early 1990s[Progressive Grocer November 1992 p 50] It follows that theaverage store protability for these chains equals $301054 peryear Therefore the ratio of total menu cost to net margin forChains AndashD ranges between 304ndash379 percent for an average of352 percent Thus the menu costs we report in this study repre-sent a signicant share of supermarketsrsquo prots

Another way to look at the menu cost gures we report is toexpress them relative to the frequency of price changes In thelast row of Table IV we present the menu cost gures per pricechange for each chain As the table indicates the cost of changinga price in Chains AndashD ranges between $046ndash$068 for an averageof $052 For Chain E the gure is substantially larger $133 perprice change29 These gures are lower than the estimated cost of

27 This is the average of two different estimates $12945432 and$17160000 The source of the rst gure is internal record of a supermarketchain of the type and size studied here The second gure comes from Supermar-ket Business [1993 p 52]

28 We also measured the menu costs in terms of controllable operating ex-penses (which are the portion of costs that the retailer has direct control over andtherefore are often the costs that the retailer is most focused on managing) andgross margins (which measure the supermarket revenues minus direct cost of theproducts it sells) We nd that the menu costs comprise 313 percent of controlla-ble operating expenses and 281 percent of gross margins at these chains on aver-age Finally if we measure the menu costs relative to the number of productscarried per store (about 25000) then we nd that the menu costs per productaverage $423 for Chains AndashD See Table IV and its footnotes for details

29 We can also try to express the menu cost gures relative to the numberof individual items sold by these chains each year (Note the difference betweennumber of products carried and number of items sold As an example a TartarControl Crest 8oz would be considered a product carried and 300 units of themsold per year would be considered number of items sold) Using $170 as the aver-age price of all the products sold we nd that the menu cost per item sold for thefour chains is in the range of $00103ndash$00129 for an average of $00119 (see TableIV second to last row) To see the relative magnitude of these gures note thataccording to Berkowitz Kerin and Rudelius [1986 p 319] the goal of the super-market chains of the type we study ldquo is to make 1 penny of prot on each dollarof salesrdquo Thus menu cost per item sold when adjusted for the average price

THE MAGNITUDE OF MENU COSTS 813

$200ndash$300 per price change reported by Slade [1996a] Thereare several possible reasons for this (1) our menu cost gures arebased on actual measurements of the resources that go into theprice change process whereas she estimates menu costs econo-metrically as model coefcients using a mix of store-level priceand aggregate cost data (2) we cover 25000 products that thesupermarkets carry rather than a single product category (3) ourmenu cost gures do not include all components of menu costsand (4) there could be differences in wage rates that may be im-portant given the signicance of the labor cost component inmenu costs

V2 The Effect of Menu Costs on the Price Change Activity of theSupermarkets

In this section we present evidence which suggests that thesemenu costs may be forming a barrier to price change activity Tobegin with consider the effect of the item pricing law on the pricechange activity of Chain E The data on the weekly frequency ofprice changes in each chain are displayed in the last two rows ofTable I According to these gures the average weekly frequencyof price changes in Chain E is only 1578 Thus on average ChainE changes the prices of only 631 percent of its products eachweek In contrast the average weekly frequency of price changesat Chains AndashD ranges from 3223 to 4316 for the four-chain aver-age of 3916 price changes weekly So Chains AndashD change priceson 1289 to 1726 percent of their products each week yielding afour-chain average of 1566 percent Thus Chain E which facesthe item pricing law changes prices only about one-third timesas frequently as do Chains AndashD30

Moreover within Chain E there are 400 products that areexempt from the item pricing law and thereby face lower menucosts We nd that there are an average of 83 weekly pricechanges for these products yielding 21 percent of these productschanging prices So within Chain E they change prices over threetimes as frequently for products with lower menu costs than for

roughly equals one-half of their target net prot per item which seemssubstantial

30 However note that our comparison of the two types of chains may not becompletely ceteris paribus because these stores are located in different states andtherefore there may be other chain-specic factors (in addition to item pricinglaws) that distinguish these stores We do not have any specic information onthese differences We do know however that the stores in these chains are similarin size and carry similar sets of products

QUARTERLY JOURNAL OF ECONOMICS814

the products with higher menu costs Note that this nding is onthe price change activity within the same chain offering almost anatural experiment on the impact of menu costs on the chainrsquospricing behavior Hence we provide evidence both across chainsas well as across products within a chain that as the costs ofchanging price go up the frequency of price changes goes downThus the menu costs we nd are signicant enough to affect thechainrsquos price change practice

We also have additional evidence from Chains A B and Dabout these menu costs being a barrier to certain price changesand it is summarized in Table V According to the Price Manage-ment Department of Chain A the chain experiences cost in-creases on 860 products in an average week to which it wouldlike to react with a price increase31 However on average 22 per-cent of these price increases are not implemented immediatelybecause the cost of changing prices for these products is too highto make it economically worthwhile Figures of the same magni-tude were reported by other chains For example Chain D experi-ences cost increases for 961 products in an average week Out ofthese the chain adjusts prices of only 633 products The re-maining 34 percent of the prices are left unadjusted because ofthe menu costs Similarly Chain B nds it economically ineffi-cient to adjust prices of 508 ie 30 percent of its products eachweek because of menu costs This provides additional evidencethat the menu costs incurred by these chains are preventing priceadjustments to some costs changes leading to price rigidities ofthe products involved32 Note that although we do not have simi-lar data for Chain E we would expect signicantly lower num-bers on this measure at that chain These gures also suggest anupper bound on the benet of complete price exibility under thecurrent pricing practice of weekly price adjustments Howeverif new technologies (eg ESL systems) and new pricing prac-tices (eg a decentralization of the price change decisions) are

31 Our data contain information only on the frequency of cost increasesAlthough it is more than likely that the supermarkets are experiencing cost de-creases as well our data set contained no information on such decreases

32 Menu costs may even be playing a role in the observed movement towardpricing strategies that rely on fewer price changes such as EDLP [Blattberg andNeslin 1989 Lattin and Ortmeyer 1991 Marketing News April 13 1992 p 8]According to Progressive Grocer [November 1992 p 50] ldquoA growing number ofoperators say they have switched from high-low pricing [to EDLP] They cite theinefciencies of making frequent price changes rdquo Similarly Hoch Dreze andPurk [1994 p 16] state that EDLP lowers operating costs by lowering ldquo in-store labor costs because of less frequent changeovers in special displaysrdquo

adopted allowing a fundamental change in the way the pricingmechanism is currently set the managers could consider morefrequent price change activity (eg multiple times each week) asmenu costs go down

In this paper we measure the menu costs at the chainsrsquo cur-rent level of price change activity It may be worthwhile to specu-late on the shape of the cost function relating menu costs to thefrequency of price changes by assessing how these costs wouldchange if the price change activity were to increase or to decreaseIt seems likely that many of the costs we report in this paper will(approximately) change linearly with additional price changeswithin the current range of price changes the chains are under-taking (plus or minus perhaps a thousand per week) For ex-ample the labor costs associated with changing a shelf price tagcosts of verifying price changes and the costs of mistakes oc-curring during this process all increase linearly with the fre-quency of price changes This is because most of the time-consuming steps involved in the price change process must berepeated each time an additional shelf price tag is changed (seeTable II) Further we were unable to nd many tasks that gener-ated signicant returns to scale It is unclear what cost savingsare available if the price change activity drops substantially be-

QUARTERLY JOURNAL OF ECONOMICS816

low the levels it is at now Clearly if price changes were nearzero or done less frequently than weekly (say monthly) therecould be major differences in these costs

What is less clear is how these costs would change at moreextreme levels of price change activity With less frequent pricechanges the menu costs could probably be reduced signicantlyalthough the cost of deciding what prices to set initially and thecost of putting the initial shelf price tags would still remain as alower bound of the menu cost However for achieving more priceexibility by changing prices more frequently (ie multiple timeseach week) substantial changes must be undertaken At presentthe supermarket chains are set up to make the majority of theirprice changes on a weekly basis with the appropriate systems inplace to make this process most efcient For example in orderto save costs and to have higher quality price tags (eg withcolor more details greater clarity glossy etc) the chains oftensend new price tag requests to a printing shop which takes threedays to print and deliver the labels to each store Then giventhe large number of price changes taking place and the goals ofminimizing customer disruptions and labor costs (such as over-time pay) and coordinating with advertised price promotions theprices are changed in the store over a two-to-three-day period (seeTable VI) The combination of these schedule and built-in lags isacceptable under the current practice of changing prices weeklybut would have to be adjusted dramatically to allow for signifi-cantly more frequent price changes on a regular basis

Perhaps even more imposing are the costs of changing themanagerial costs associated with the current weekly system ofprice changes The process of pricing at this organizational levelis not a self-contained activity taking place in isolation from otheroperations of the supermarket management Rather it is a partof a larger system of business decisions and operations The cur-rent process of operations (such as data collection and theiranalysis management meetings coordination of the decisionsacross functional areas etc) is set up to function on a weeklybasis33 Further these management accounting and logisticssystems are currently built around a tremendous amount of in-

34 For example under the current system a chainwide category manageroperating at the corporate headquarters needs to study and assess numerouspieces of detailed information such as competitorsrsquo price and sale information fromthe last week the past weekrsquos sales at the own chain manufacturersupplier pro-motions wholesale price reductions coop allowances new product offerings shelfspace decisions coordination with newspaper advertising logistics at the ware-houses as well as at each store store differences in terms of customer characteris-tics and competitive environments productshelf selection and layout etc

35 If the supermarket chains indeed restructure the entire price change pro-cess and begin to change prices much more frequently (say two-to-three times aweek) on a regular basis then the shape of this cost function could change in anunpredictable way

V3 Relating Our Findings to the Existing Theoretical Models ofMenu Costs

In order to assess the magnitude of these menu cost guresin the context of the existing theoretical menu cost literatureconsider the following calculation experiments done within theframework of two theoretical menu cost models Blanchard andKiyotaki [1987] study a general equilibrium menu cost modelwith monopolistic competition and with unit elasticity of aggre-gate demand with respect to real money balances According totheir calculations menu costs of the magnitude of 008 percent ofrevenues which they consider ldquovery smallrdquo may be sufcient toprevent adjustment of prices Ball and Romer [1990] conductsimilar calculations in the framework of a model with imperfectcompetition and menu costs They nd that for plausible markupand labor elasticity parameter values menu costs needed to pre-vent price adjustment are 070 percent of revenues which as theysuggest are nonnegligible For smaller menu costs eg 004 per-cent of the revenue which Ball and Romer consider ldquotrivialrdquo im-plausibly large values of markup and labor elasticity parametersare needed to prevent price adjustment to monetary shocks

According to the gures in Table IV the reported menu costto revenues ratio for Chains AndashD averages 070 percent rangingfrom 061 percent to 076 percent These are signicantly largerthan the ldquotrivialrdquo 004 or 008 percent gures mentioned abovesuggesting that the menu cost gures we nd here are nontrivialFurther under the model and parameter values considered byBlanchard and Kiyotaki [1987] the menu cost gures we nd arehigher than the theoretical minimum needed to form a barrier toprice adjustments Under the model and parameter values con-sidered by Ball and Romer [1990] the reported menu costreve-nue ratio for all but one chain reaches or crosses the theoreticalthreshold of 070 needed to form a barrier to price adjustmentsThe existence of numerous unmeasured menu cost componentsdiscussed in subsection III5 also raises the possibility that theactual menu costs incurred by these chains are signicantlyhigher than that threshold This suggests that the menu costs wereport may be large enough to form a barrier to nominal priceadjustments when interpreted in the context of these models

An issue of interest in this literature is time-dependent ver-sus state-dependent pricing rules (see for example Caplin andLeahy [1991]) The evidence from our data set on the timing of

THE MAGNITUDE OF MENU COSTS 819

price changes suggests that the price change decisions in thesesupermarkets have a strong time-dependent price-setting ele-ment36 For example according to Table VI the prices in Chain Aare changed weekly according to the following schedule the pricechanges of general merchandise that is advertised is done Satur-day nights grocery and produce prices are changed Sundaynights the rest of the general merchandise prices are changed onMonday nights and the prices of advertised grocery items arechanged on Tuesday nights Thus as the gures in Table VI indi-cate over 96 percent of the price changes are done during Sundayand Monday nights However this does not imply that state-dependent pricing rules are unimportant Even if price changesacross product categories follow a prescheduled weekly time ta-ble the prices of which products to change is likely to be a state-dependent decision For example it could depend on changes insupply and demand conditions such as competitorsrsquo price changedecisions Indeed Levy Dutta and Bergen [1996] use retailstore-level orange juice price and cost data to demonstrate thatthe extent of price response to cost shocks that is the extent ofprice rigidity may depend on the nature of supply shocks37

We do not want to overstate the usefulness of our data fordirectly addressing the issue of monetary nonneutrality On onehand authors such as Caplin and Spulber [1987] have demon-strated that under certain conditions individual price rigiditymay not be sufcient for aggregate price rigidity but unfortu-nately our data do not speak directly to this issue38 On the otherhand authors such as Akerlof and Yellen [1985] Mankiw [1985]Parkin [1986] and Caplin and Leahy [1997] have shown that even

36 Danziger [1983] Caballero [1989] and Ball and Mankiw [1994] suggestthat time-dependent price adjustment of the type documented here can be optimalif the cost of gathering information about the state exceeds the cost of making theprice adjustment itself

37 We also considered the possibility of convexities in the cost of changingprices Our data do not suggest many convexities since the labor time spent inthe price tag change process the cost of printing and delivering price tags andin-store supervision time do not change with the size of a price change The onlymeasurable component of menu costs that could be convex is the cost of mistakesmade the larger the price change the higher the probability of a customer notic-ing the mistake and the larger the amount required to be refunded as compensa-tion Among the unmeasured components of menu cost the cost of corporatemanagerial time may increase with the size of a price change because larger pricechanges may require more serious consideration

38 Also see Balke and Wynne [1996] and Bryan and Cecchetti [1996] Sincewe do not have measures of how menu costs change over time our data also havelittle to say about time variation in menu costs or about the relationship betweenmenu costs and ination which during the period of the data collection (1991ndash1992) averaged about 3 percent annually

QUARTERLY JOURNAL OF ECONOMICS820

small menu costs can be relevant since they may be sufcient togenerate substantial aggregate nominal rigidity and thus largebusiness cycles Therefore as Blinder [1994] Kashyap [1995]and Slade [1996a] emphasize it is important to search for directevidence that such costs are indeed present at the micro level Bydirectly identifying documenting and measuring the magnitudeof menu costs at the store level we are taking an important stepin that direction

VI CONCLUSION AND FUTURE RESEARCH

Our main contribution is that we provide direct microeco-nomic evidence on the actual magnitude of menu costs for fourlarge U S retail supermarket chains The annual menu costs perstore at these chains average $105887 comprising 070 percentof revenues 352 percent of net prot margins and $052 perprice change on average

Further we provide evidence which suggests that thesemenu costs may be forming a barrier to price changes Specifi-cally we show that (1) supermarket chains not subject to itempricing law change prices two and a half times more frequentlythan the chain that is subject to the law (2) within the chain thatis subject to the item pricing law they change prices over threetimes as frequently for products that are exempt from this lawthan for the products which are subject to this law and (3) wend that these chains do not adjust prices of up to one-third ofthe products for which they face cost increases because of menucost considerations

When we relate these ndings to the existing theoreticalmodels of menu costs we conclude that the magnitude of menucosts we nd is large enough to be capable of having macroeco-nomic signicance Specically when considered in the context ofthe theoretical menu cost models of Blanchard and Kiyotaki[1987] and Ball and Romer [1990] we nd that the menu costgures we report are ldquonontrivialrdquo and their relative magnitudescross the minimum theoretical threshold needed to form a barrierto price adjustments

Despite the high relative magnitude of the marginal cost ofchanging price that we found the data still indicate frequentweekly price changes This is because of the high marginal bene-t of changing price which is due to the erce competition foundin the retail supermarket industry That marginal benets may

THE MAGNITUDE OF MENU COSTS 821

outweigh the marginal costs of changing prices in this industryhowever does not rule out the possibility that menu costs of themagnitude we nd here can create substantial nominal rigidityin other industries or markets In less competitive industries andmarkets menu costs of the type and magnitude we documenthere are likely to have a bigger impact on the frequency of priceadjustment and consequently on the degree of price rigidity

At a minimum the direct dollar measures of menu costs wereport here can be used as a starting point for future research onmeasuring their magnitude in other industries and establish-ments We anticipate that these menu costs will be similar inother markets which rely on posted prices (such as drugstoresdepartment stores etc) because the steps involved in the pricechange process are likely to be similar What may differ are thefrequency of price changes and the labor wage rates at thesestores For example since supermarket chains change thousandsof prices each week the total annual menu costs incurred bythese chains per store are likely to be high in comparison to otherretail formats such as chain drugstores or department storesThere are however a variety of industries for which the stepsinvolved in changing prices would be signicantly different fromthose reported in our study For example business-to-businesssales which often rely on a sales force will require changes in thelist price sheets changes in the instructions to the sales forcewhich may include education and discussion with the salespeoplein the company and so forth These business-to-business pricesalso often have more complex pricing schemes including quantitydiscounts bundling and individually negotiated prices As an-other example the composition of the cost of changing the news-stand prices of magazines [Cecchetti 1986] or the prices ofproducts sold through catalogs [Kashyap 1995] are different frommany of the menu cost components we discuss here Further thending that a centralization of pricing decisions makes the store-level managerial component of menu cost relatively small sug-gests that the managerial menu costs likely are highest insettings where price change decisions are decentralized Thus fu-ture empirical work should look at menu cost and its compositionin a variety of other industries markets and products with bothcentralized as well as decentralized price change decisions in or-der to see whether the magnitude of these costs can be general-ized and benchmarks can be established Further there aretechnological changes taking place in this and other industries

that promise to alter the structure of menu costs which deserveattention At the theoretical level our ndings suggest that it maybe worthwhile to explore models which incorporate the idea ofitem pricing laws as an additional component of menu costs

grocery operating expenses is labor costs [Hoch Dreze andPurk 1994]14

III2 Costs of Printing and Delivering New Price Tags

There are direct costs associated with printing and deliv-ering the price and sign tags The order must be recorded andprocessed at the chain sent to the printer recorded and pro-cessed at the printer printed packaged and then delivered toeach store The cost per tag is usually quite low $0017 per tagat Chain A which includes stock costs of $00118 per tag impres-sion and data center operator costs of $00037 per tag and mailroom handling costs of $00010 per tag There are however manyprice changes undertaken each week In total the costs of print-ing and delivering the price and sign tags range from $3048 to$10018 averaging $6014 per store per year (see Table III)These costs comprise less than 6 percent of the total menu costswe report

III3 Costs of Mistakes Made in the Process of Changing Prices

Despite the labor put into checking to make sure that theprice changes are done correctly there are still many price mis-takes that are not caught until customers discover them through-out the week and these mistakes impose costs on the chainClearly the costs associated with these errors must be consideredwhen deciding whether to change prices or not and therefore area relevant dimension of menu costs These mistakes can occur sooften that they were a feature of a Dateline segment on U Ssupermarket chains [NBC April 1992] and an article in MoneyMagazine [April 1993] Both the Money Magazine article andGoodstein [1994] report that on average 10 percent of the prod-ucts they examined had price mistakes A more recent study bythe Federal Trade Commission [1996] reports a total error rate ofabout 5 percent

The menu costs associated with these mistakes include lost

14 Our measure of labor cost may overstate the true costs of changing pricesif supermarkets hoard labor to save hiring and ring costs However this is notlikely to be the case for several reasons First the labor costs of changing priceswe report are based on actual measurements of the minimum amount of time andlabor required to accomplish the task rather than on the number of employeeshired to change prices at the store Second the adjustment in the amount of laboris usually done through hours worked which makes cost of hiring and ring lessrelevant And third the workers on the oor are routinely moved from task totask according to the need These tasks include stocking cleaning price changingcustomer service etc The workers employed by supermarket chains are alwaysbusy and so the opportunity cost of changing price is not zero Therefore laborhoarding is not likely to be an important factor in our measurements

QUARTERLY JOURNAL OF ECONOMICS806

cashier time to correct the errors scan guarantee refunds andinventory mistakes associated with incorrect price tags15 Lostcashier time is measured here in terms of wage payments Scanguarantee refunds are additional price reductions beyond the er-ror or additional items given away for free because of the mis-take Finally the inventory mistakes costs we report include onlythe cost of stockouts which occur when shelf price is lower thanintended

The mistake costs were available at Chains A C and D andthey range from $19135 to $20692 for an average of $20140 perstore annually (see Table III) These costs are the second largestcomponent of menu costs in our study comprising about 19 per-cent of the total

III4 Costs of In-Store Supervision Time Spent on ImplementingPrice Changes

Managers at the store level spend time overseeing imple-menting and troubleshooting the price change process OnlyChains A and B had a measure of the menu costs associated withthis in-store supervision time and both of these came from a self-reported number of hours spent on changing prices by the manag-ers at these chains The hours spent on changing prices were thesame across the chains approximately ve hours per week Thusthe menu costs for in-store supervision time came to $4241 and$6692 per store annually for Chains A and B respectively (seeTable III) These costs comprise less than 6 percent of the totalmenu costs we report in this paper However notice that thesemeasures do not include the cost of the management time spenton price change decisions made at corporate headquarters whichis discussed next

III5 Components of Menu Costs We Are Unable to Measure inDollar Terms

Our data set does not contain the exact dollar measures ofsome menu cost components One such component is the cost ofcorporate management time spent on price change decisions16 In

15 Other likely costs of price mistakes that we do not consider explicitlybecause we are unable to measure them in dollar terms are legal problems (whenthe scanner price is higher than the shelf price) loss in customer goodwill anddecreased protability (when the scanner price is lower than the shelf price)

16 It has been suggested that the cost of managerial decisions is one of themost important components of menu cost See for example Ball and Mankiw[1994] Kashyap [1995] and Meltzer [1995] Since the ESL system was not de-

THE MAGNITUDE OF MENU COSTS 807

the supermarket chains we study prices are generally set at cor-porate headquarters in a weekly meeting where the manager incharge of setting prices looks at a variety of information including(a) any manufacturer wholesale price changes promotions andother related issues (b) past sales for this product and (c) com-petitorsrsquo prices Based on this information and on discussionswith other managers the price-setting manager decides whetherto change prices and if so by how much

To estimate the magnitude of these managerial componentsof the menu costs consider the following In an average chainthere is at least one executive of merchandising who devotesmost of hisher time to pricing decisions In addition there areup to three senior managers who would deal with pricing andto whom category managers report There are also ten-to-twelvecategory managers who are responsible for setting prices on allthe products within their category An additional two-to-fourpeople spend full time handling the implementation of pricechanges across retail outlets coordinating the printing and deliv-ery of price tags and handling pricing problems in the systemAnother ve-to-seven workers gather the data on competitorsrsquoprices and analyse both the competitorsrsquo data and the storersquos ownscanner data to put it in a form useable by managers makingpricing decisions Thus in total there are about 21ndash27 peopleworking at the corporate headquarters on price change decisionsAssuming $150000 as the average annual salary of the executiveof merchandising and senior managers $100000 for categorymanagers and $50000 for the rest the chainwide managerialcost falls in the neighborhood of $23ndash$29 million a year whichseems a substantial amount However note that these pricing de-cision are made for the entire chain and therefore the costs perstore are signicantly less especially for the larger chains Forexample using $29 million as the upper bound the additionalannual menu cost per store for Chains AndashD which on averageoperate about 400 stores each averages about $7250 which ismuch lower than expected and is due to the centralization of theprice change decisions in the chains we study17

signed to save the costs of corporate headquarter managerial time spent on pricechange decisions the ESL company did not measure this component of menucosts The estimates reported in this section are based on the information receivedfrom the ESL company executives

17 A decentralization of the price change process say by allowing the store-level managers to make price change decisions can change these gures tremen-dously For example consider the following thought experiment conducted using

QUARTERLY JOURNAL OF ECONOMICS808

Our menu cost measures also do not include the cost ofchanging prices of direct store delivery (DSD) products Theseproducts are almost completely handled by manufacturers in-cluding stocking monitoring inventories and setting and chang-ing prices18 We have data on the weekly frequency of pricechanges of DSD products in Chain E In an average week thereare 174 price changes of DSD products which is about 10 percentof the supermarketrsquos total weekly price changes Using the costof changing the price of a regular product $133 (see Section IVfor details) the annual cost of changing prices of the DSD prod-ucts in this chain roughly equals $1203419 Our menu cost mea-sures do not include these gures since we do not have similardata for the other chains20

III6 Total Menu Costs

The total annual menu costs reported for each chain perstore are listed in the last row of Table III As the table indicatesthe menu costs range from $91416 to $114188 for an average of$105887 per store per year21 Note that these menu cost mea-

the average annual per store gures for Chains AndashD Suppose that the supermar-ket chains decentralize the price change process by hiring for each store only one-quarter of the price change managing team while at the same time they com-pletely eliminate the corporate level team The resulting annual menu cost perstore would be $830887 ( 5 $105887 1 $725000) which would dwarf any of themeasurable menu cost gures we report in this study Even if the average storeonly hired just the merchandising manager at the annual cost of $150000 itwould still incur annual managerial cost of about $255887 ( 5 $105887 1$150000) In other words such a trivial decentralization would double the store-level menu costs This would indeed make the cost of price change decisions themost important component of menu cost

18 DSD products usually are high-volume fast-moving or perishable prod-ucts such as milk soda eggs bread dairy snacks etc In the chains we studyabout 10ndash20 percent of the products are of a DSD type but that share may reachas much as 40 percent of the products carried [Direct Store Delivery Work Groupet al 1995]

19 The process of changing prices of DSD and of regular products is similarBut with DSD products there are additional costs of the time spent on driving tothe store parking and setting up the price change process at each store

20 Our measures of menu cost also do not incorporate the cost of informingconsumers about price changes which can take a variety of forms such as newspa-per ads and inserts TV and radio ads in-store promotion signs etc Finally wehave no data on lost customer goodwill and damaged reputation caused by dis-crepancies between price tag and cash register [Okun 1981 Carlton and Perloff1994 Haddock and McChesney 1994]

21 The variation in the menu costs across the chains is mostly due to wagerate and labor-efciency variations Also note that since the supermarket chainsin our sample are similar in the size of their stores carry similar sets of productsand follow similar processes of price change and price change decisions it is rea-sonable to believe that the chains incur similar types of costs Therefore as notedunderneath Table III these menu cost measures are computed by replacing theunreported gures by the averages of the available values from the other chains

sures include only the components we could accurately measurein dollar terms which are discussed in subsections III1ndashIII4

IV ITEM PRICING LAWS AND MENU COSTS

In this section we provide evidence on the menu costs for anadditional chain (Chain E) which unlike the other four chainsoperates in a state with an item pricing law The most importantaspect of item pricing laws is that they require a price tag on eachindividual item sold not just on the shelf which is what the otherfour chains in our sample do For example the item pricing lawin Connecticut requires that the grocers ldquoshall mark or cause tobe marked each consumer commodity which bears a UniversalProduct Code with its retail pricerdquo 22 From a menu cost perspec-tive the requirement of posting prices on every item (in additionto the shelf price tag) introduces additional costs in the processof changing prices

Although most of the steps involved in changing prices arethe same for both types of chains stores that are subject to itempricing laws have to undertake additional steps to obey this law23

The labor cost component of menu costs in Chain E totals $75127a year of which $49710 is the cost of the labor time spent onchanging the prices of individual items $3234 is the cost of thelabor time spent on shelf tag replacements and $22183 is thecost of the labor time spent on sign changes (see Table III)24 Anadditional $44168 is spent annually putting prices on new itemsas they are brought to the shelves Although we do not includethis last gure in our menu cost measures because we do not haveinformation on how much of it is due to price change activity andhow much due to just pricingmdashthese costs are clearly a directconsequence of the item pricing law The printing and deliverycost of price tags and price signs are $7644 and the mistake

22 Public Act No 75ndash391 An Act Concerning Pricing of Consumer Merchan-dise [Public Acts of the State of Connecticut 1975 Vol 1 p 390]

23 These steps which are in addition to the regular steps undertaken toreplace price tags on the shelves include (1) obtaining item price tags (2) settingup workstations (3) locating the product (4) removing an item from the shelf (5)removing old price tag (6) setting marking gun (7) applying new price tag and(8) returning the item back to the shelf

24 Since we do not have a measure of the cost of labor time spent on signchanges and the cost of in-store managerial supervision time for this chain weuse the average of the chains that report them (A and D) Note also that thehourly wage rate of $907 paid by Chain E is lower than the hourly wage of about$1400ndash$2000 paid by Chains AndashD

QUARTERLY JOURNAL OF ECONOMICS810

25 Further note that the chains with smaller menu costs are likely tochange their prices more frequently which suggests that the gures of the totalannual menu costs understate the differences between Chain E and the otherchains Indeed despite the large difference in the menu cost per price change thetotal annual menu costs per store for Chain E ($109036) are more comparable tothose of Chains AndashD ($105887)

26 In calculations that follow we use industry averages because (1) thechains did not share this proprietary information with us and (2) we were re-quired to keep the identity of these chains condential as some of these numbersare detailed enough to enable some readers to identify the chains under study

costs are $20799 These gures along with the amount of $5466for the cost of in-store managerial supervision time yield totalannual menu costs of $109036 per store

Although the magnitude of the total annual menu costs seemsimilar to the other four chains note that the average weeklyfrequency of price changes in Chain E is only 1578 which is only403 ( 5 15783916) percent of the price changes made by theother four chains Thus the average menu cost per price changefor Chain E is $133 (see Table IV last row) In contrast the corre-sponding gures for Chains AndashD average $052 Hence the menucosts per price change incurred by the supermarket chain facingitem pricing laws are more than two and a half times the amountincurred by chains that are not subject to this law25 Overallthese ndings suggest that legal restrictions of the type of itempricing laws can have a signicant impact on the menu costs in-curred by sellers

V SIGNIFICANCE OF THE MENU COSTS

The next natural question to ask is how important are thesecosts To address this question we (1) provide several relativemeasures of the menu costs (2) discuss the effect of the menucosts on supermarketsrsquo price change activity and (3) discuss mac-roeconomic implications by relating our ndings to the existingtheoretical models of menu costs In each case we provide addi-tional evidence to help assess the importance of these menu costs

V1 Relative Measures of the Menu Costs

In order to assess the relative magnitude of the menu costsreported in Section IV we now present the menu cost gures rela-tive to the average store-level revenues and net prot margins26

In addition we present the menu cost gures per price changeThe annual average revenues of a large U S supermarket

chain of the type and size included in our sample is $15052716

per store27 According to the second row of Table IV the ratio ofmenu costs to revenues for Chains AndashD ranges between 061ndash076percent averaging 070 percent28 We relate the size of thesegures to the existing theoretical menu cost models in sub-section V3

Net prot margin which measures the revenues minus allcosts is approximately 1ndash3 percent of revenues for these chains[Montgomery 1994] so we use 2 percent as a working averageThe reason for the low prot rate in this industry is the intensecompetition [Calatone et al 1989] especially at the regional level[Chevalier 1995] which has been increasing since the early 1990s[Progressive Grocer November 1992 p 50] It follows that theaverage store protability for these chains equals $301054 peryear Therefore the ratio of total menu cost to net margin forChains AndashD ranges between 304ndash379 percent for an average of352 percent Thus the menu costs we report in this study repre-sent a signicant share of supermarketsrsquo prots

Another way to look at the menu cost gures we report is toexpress them relative to the frequency of price changes In thelast row of Table IV we present the menu cost gures per pricechange for each chain As the table indicates the cost of changinga price in Chains AndashD ranges between $046ndash$068 for an averageof $052 For Chain E the gure is substantially larger $133 perprice change29 These gures are lower than the estimated cost of

27 This is the average of two different estimates $12945432 and$17160000 The source of the rst gure is internal record of a supermarketchain of the type and size studied here The second gure comes from Supermar-ket Business [1993 p 52]

28 We also measured the menu costs in terms of controllable operating ex-penses (which are the portion of costs that the retailer has direct control over andtherefore are often the costs that the retailer is most focused on managing) andgross margins (which measure the supermarket revenues minus direct cost of theproducts it sells) We nd that the menu costs comprise 313 percent of controlla-ble operating expenses and 281 percent of gross margins at these chains on aver-age Finally if we measure the menu costs relative to the number of productscarried per store (about 25000) then we nd that the menu costs per productaverage $423 for Chains AndashD See Table IV and its footnotes for details

29 We can also try to express the menu cost gures relative to the numberof individual items sold by these chains each year (Note the difference betweennumber of products carried and number of items sold As an example a TartarControl Crest 8oz would be considered a product carried and 300 units of themsold per year would be considered number of items sold) Using $170 as the aver-age price of all the products sold we nd that the menu cost per item sold for thefour chains is in the range of $00103ndash$00129 for an average of $00119 (see TableIV second to last row) To see the relative magnitude of these gures note thataccording to Berkowitz Kerin and Rudelius [1986 p 319] the goal of the super-market chains of the type we study ldquo is to make 1 penny of prot on each dollarof salesrdquo Thus menu cost per item sold when adjusted for the average price

THE MAGNITUDE OF MENU COSTS 813

$200ndash$300 per price change reported by Slade [1996a] Thereare several possible reasons for this (1) our menu cost gures arebased on actual measurements of the resources that go into theprice change process whereas she estimates menu costs econo-metrically as model coefcients using a mix of store-level priceand aggregate cost data (2) we cover 25000 products that thesupermarkets carry rather than a single product category (3) ourmenu cost gures do not include all components of menu costsand (4) there could be differences in wage rates that may be im-portant given the signicance of the labor cost component inmenu costs

V2 The Effect of Menu Costs on the Price Change Activity of theSupermarkets

In this section we present evidence which suggests that thesemenu costs may be forming a barrier to price change activity Tobegin with consider the effect of the item pricing law on the pricechange activity of Chain E The data on the weekly frequency ofprice changes in each chain are displayed in the last two rows ofTable I According to these gures the average weekly frequencyof price changes in Chain E is only 1578 Thus on average ChainE changes the prices of only 631 percent of its products eachweek In contrast the average weekly frequency of price changesat Chains AndashD ranges from 3223 to 4316 for the four-chain aver-age of 3916 price changes weekly So Chains AndashD change priceson 1289 to 1726 percent of their products each week yielding afour-chain average of 1566 percent Thus Chain E which facesthe item pricing law changes prices only about one-third timesas frequently as do Chains AndashD30

Moreover within Chain E there are 400 products that areexempt from the item pricing law and thereby face lower menucosts We nd that there are an average of 83 weekly pricechanges for these products yielding 21 percent of these productschanging prices So within Chain E they change prices over threetimes as frequently for products with lower menu costs than for

roughly equals one-half of their target net prot per item which seemssubstantial

30 However note that our comparison of the two types of chains may not becompletely ceteris paribus because these stores are located in different states andtherefore there may be other chain-specic factors (in addition to item pricinglaws) that distinguish these stores We do not have any specic information onthese differences We do know however that the stores in these chains are similarin size and carry similar sets of products

QUARTERLY JOURNAL OF ECONOMICS814

the products with higher menu costs Note that this nding is onthe price change activity within the same chain offering almost anatural experiment on the impact of menu costs on the chainrsquospricing behavior Hence we provide evidence both across chainsas well as across products within a chain that as the costs ofchanging price go up the frequency of price changes goes downThus the menu costs we nd are signicant enough to affect thechainrsquos price change practice

We also have additional evidence from Chains A B and Dabout these menu costs being a barrier to certain price changesand it is summarized in Table V According to the Price Manage-ment Department of Chain A the chain experiences cost in-creases on 860 products in an average week to which it wouldlike to react with a price increase31 However on average 22 per-cent of these price increases are not implemented immediatelybecause the cost of changing prices for these products is too highto make it economically worthwhile Figures of the same magni-tude were reported by other chains For example Chain D experi-ences cost increases for 961 products in an average week Out ofthese the chain adjusts prices of only 633 products The re-maining 34 percent of the prices are left unadjusted because ofthe menu costs Similarly Chain B nds it economically ineffi-cient to adjust prices of 508 ie 30 percent of its products eachweek because of menu costs This provides additional evidencethat the menu costs incurred by these chains are preventing priceadjustments to some costs changes leading to price rigidities ofthe products involved32 Note that although we do not have simi-lar data for Chain E we would expect signicantly lower num-bers on this measure at that chain These gures also suggest anupper bound on the benet of complete price exibility under thecurrent pricing practice of weekly price adjustments Howeverif new technologies (eg ESL systems) and new pricing prac-tices (eg a decentralization of the price change decisions) are

31 Our data contain information only on the frequency of cost increasesAlthough it is more than likely that the supermarkets are experiencing cost de-creases as well our data set contained no information on such decreases

32 Menu costs may even be playing a role in the observed movement towardpricing strategies that rely on fewer price changes such as EDLP [Blattberg andNeslin 1989 Lattin and Ortmeyer 1991 Marketing News April 13 1992 p 8]According to Progressive Grocer [November 1992 p 50] ldquoA growing number ofoperators say they have switched from high-low pricing [to EDLP] They cite theinefciencies of making frequent price changes rdquo Similarly Hoch Dreze andPurk [1994 p 16] state that EDLP lowers operating costs by lowering ldquo in-store labor costs because of less frequent changeovers in special displaysrdquo

adopted allowing a fundamental change in the way the pricingmechanism is currently set the managers could consider morefrequent price change activity (eg multiple times each week) asmenu costs go down

In this paper we measure the menu costs at the chainsrsquo cur-rent level of price change activity It may be worthwhile to specu-late on the shape of the cost function relating menu costs to thefrequency of price changes by assessing how these costs wouldchange if the price change activity were to increase or to decreaseIt seems likely that many of the costs we report in this paper will(approximately) change linearly with additional price changeswithin the current range of price changes the chains are under-taking (plus or minus perhaps a thousand per week) For ex-ample the labor costs associated with changing a shelf price tagcosts of verifying price changes and the costs of mistakes oc-curring during this process all increase linearly with the fre-quency of price changes This is because most of the time-consuming steps involved in the price change process must berepeated each time an additional shelf price tag is changed (seeTable II) Further we were unable to nd many tasks that gener-ated signicant returns to scale It is unclear what cost savingsare available if the price change activity drops substantially be-

QUARTERLY JOURNAL OF ECONOMICS816

low the levels it is at now Clearly if price changes were nearzero or done less frequently than weekly (say monthly) therecould be major differences in these costs

What is less clear is how these costs would change at moreextreme levels of price change activity With less frequent pricechanges the menu costs could probably be reduced signicantlyalthough the cost of deciding what prices to set initially and thecost of putting the initial shelf price tags would still remain as alower bound of the menu cost However for achieving more priceexibility by changing prices more frequently (ie multiple timeseach week) substantial changes must be undertaken At presentthe supermarket chains are set up to make the majority of theirprice changes on a weekly basis with the appropriate systems inplace to make this process most efcient For example in orderto save costs and to have higher quality price tags (eg withcolor more details greater clarity glossy etc) the chains oftensend new price tag requests to a printing shop which takes threedays to print and deliver the labels to each store Then giventhe large number of price changes taking place and the goals ofminimizing customer disruptions and labor costs (such as over-time pay) and coordinating with advertised price promotions theprices are changed in the store over a two-to-three-day period (seeTable VI) The combination of these schedule and built-in lags isacceptable under the current practice of changing prices weeklybut would have to be adjusted dramatically to allow for signifi-cantly more frequent price changes on a regular basis

Perhaps even more imposing are the costs of changing themanagerial costs associated with the current weekly system ofprice changes The process of pricing at this organizational levelis not a self-contained activity taking place in isolation from otheroperations of the supermarket management Rather it is a partof a larger system of business decisions and operations The cur-rent process of operations (such as data collection and theiranalysis management meetings coordination of the decisionsacross functional areas etc) is set up to function on a weeklybasis33 Further these management accounting and logisticssystems are currently built around a tremendous amount of in-

34 For example under the current system a chainwide category manageroperating at the corporate headquarters needs to study and assess numerouspieces of detailed information such as competitorsrsquo price and sale information fromthe last week the past weekrsquos sales at the own chain manufacturersupplier pro-motions wholesale price reductions coop allowances new product offerings shelfspace decisions coordination with newspaper advertising logistics at the ware-houses as well as at each store store differences in terms of customer characteris-tics and competitive environments productshelf selection and layout etc

35 If the supermarket chains indeed restructure the entire price change pro-cess and begin to change prices much more frequently (say two-to-three times aweek) on a regular basis then the shape of this cost function could change in anunpredictable way

V3 Relating Our Findings to the Existing Theoretical Models ofMenu Costs

In order to assess the magnitude of these menu cost guresin the context of the existing theoretical menu cost literatureconsider the following calculation experiments done within theframework of two theoretical menu cost models Blanchard andKiyotaki [1987] study a general equilibrium menu cost modelwith monopolistic competition and with unit elasticity of aggre-gate demand with respect to real money balances According totheir calculations menu costs of the magnitude of 008 percent ofrevenues which they consider ldquovery smallrdquo may be sufcient toprevent adjustment of prices Ball and Romer [1990] conductsimilar calculations in the framework of a model with imperfectcompetition and menu costs They nd that for plausible markupand labor elasticity parameter values menu costs needed to pre-vent price adjustment are 070 percent of revenues which as theysuggest are nonnegligible For smaller menu costs eg 004 per-cent of the revenue which Ball and Romer consider ldquotrivialrdquo im-plausibly large values of markup and labor elasticity parametersare needed to prevent price adjustment to monetary shocks

According to the gures in Table IV the reported menu costto revenues ratio for Chains AndashD averages 070 percent rangingfrom 061 percent to 076 percent These are signicantly largerthan the ldquotrivialrdquo 004 or 008 percent gures mentioned abovesuggesting that the menu cost gures we nd here are nontrivialFurther under the model and parameter values considered byBlanchard and Kiyotaki [1987] the menu cost gures we nd arehigher than the theoretical minimum needed to form a barrier toprice adjustments Under the model and parameter values con-sidered by Ball and Romer [1990] the reported menu costreve-nue ratio for all but one chain reaches or crosses the theoreticalthreshold of 070 needed to form a barrier to price adjustmentsThe existence of numerous unmeasured menu cost componentsdiscussed in subsection III5 also raises the possibility that theactual menu costs incurred by these chains are signicantlyhigher than that threshold This suggests that the menu costs wereport may be large enough to form a barrier to nominal priceadjustments when interpreted in the context of these models

An issue of interest in this literature is time-dependent ver-sus state-dependent pricing rules (see for example Caplin andLeahy [1991]) The evidence from our data set on the timing of

THE MAGNITUDE OF MENU COSTS 819

price changes suggests that the price change decisions in thesesupermarkets have a strong time-dependent price-setting ele-ment36 For example according to Table VI the prices in Chain Aare changed weekly according to the following schedule the pricechanges of general merchandise that is advertised is done Satur-day nights grocery and produce prices are changed Sundaynights the rest of the general merchandise prices are changed onMonday nights and the prices of advertised grocery items arechanged on Tuesday nights Thus as the gures in Table VI indi-cate over 96 percent of the price changes are done during Sundayand Monday nights However this does not imply that state-dependent pricing rules are unimportant Even if price changesacross product categories follow a prescheduled weekly time ta-ble the prices of which products to change is likely to be a state-dependent decision For example it could depend on changes insupply and demand conditions such as competitorsrsquo price changedecisions Indeed Levy Dutta and Bergen [1996] use retailstore-level orange juice price and cost data to demonstrate thatthe extent of price response to cost shocks that is the extent ofprice rigidity may depend on the nature of supply shocks37

We do not want to overstate the usefulness of our data fordirectly addressing the issue of monetary nonneutrality On onehand authors such as Caplin and Spulber [1987] have demon-strated that under certain conditions individual price rigiditymay not be sufcient for aggregate price rigidity but unfortu-nately our data do not speak directly to this issue38 On the otherhand authors such as Akerlof and Yellen [1985] Mankiw [1985]Parkin [1986] and Caplin and Leahy [1997] have shown that even

36 Danziger [1983] Caballero [1989] and Ball and Mankiw [1994] suggestthat time-dependent price adjustment of the type documented here can be optimalif the cost of gathering information about the state exceeds the cost of making theprice adjustment itself

37 We also considered the possibility of convexities in the cost of changingprices Our data do not suggest many convexities since the labor time spent inthe price tag change process the cost of printing and delivering price tags andin-store supervision time do not change with the size of a price change The onlymeasurable component of menu costs that could be convex is the cost of mistakesmade the larger the price change the higher the probability of a customer notic-ing the mistake and the larger the amount required to be refunded as compensa-tion Among the unmeasured components of menu cost the cost of corporatemanagerial time may increase with the size of a price change because larger pricechanges may require more serious consideration

38 Also see Balke and Wynne [1996] and Bryan and Cecchetti [1996] Sincewe do not have measures of how menu costs change over time our data also havelittle to say about time variation in menu costs or about the relationship betweenmenu costs and ination which during the period of the data collection (1991ndash1992) averaged about 3 percent annually

QUARTERLY JOURNAL OF ECONOMICS820

small menu costs can be relevant since they may be sufcient togenerate substantial aggregate nominal rigidity and thus largebusiness cycles Therefore as Blinder [1994] Kashyap [1995]and Slade [1996a] emphasize it is important to search for directevidence that such costs are indeed present at the micro level Bydirectly identifying documenting and measuring the magnitudeof menu costs at the store level we are taking an important stepin that direction

VI CONCLUSION AND FUTURE RESEARCH

Our main contribution is that we provide direct microeco-nomic evidence on the actual magnitude of menu costs for fourlarge U S retail supermarket chains The annual menu costs perstore at these chains average $105887 comprising 070 percentof revenues 352 percent of net prot margins and $052 perprice change on average

Further we provide evidence which suggests that thesemenu costs may be forming a barrier to price changes Specifi-cally we show that (1) supermarket chains not subject to itempricing law change prices two and a half times more frequentlythan the chain that is subject to the law (2) within the chain thatis subject to the item pricing law they change prices over threetimes as frequently for products that are exempt from this lawthan for the products which are subject to this law and (3) wend that these chains do not adjust prices of up to one-third ofthe products for which they face cost increases because of menucost considerations

When we relate these ndings to the existing theoreticalmodels of menu costs we conclude that the magnitude of menucosts we nd is large enough to be capable of having macroeco-nomic signicance Specically when considered in the context ofthe theoretical menu cost models of Blanchard and Kiyotaki[1987] and Ball and Romer [1990] we nd that the menu costgures we report are ldquonontrivialrdquo and their relative magnitudescross the minimum theoretical threshold needed to form a barrierto price adjustments

Despite the high relative magnitude of the marginal cost ofchanging price that we found the data still indicate frequentweekly price changes This is because of the high marginal bene-t of changing price which is due to the erce competition foundin the retail supermarket industry That marginal benets may

THE MAGNITUDE OF MENU COSTS 821

outweigh the marginal costs of changing prices in this industryhowever does not rule out the possibility that menu costs of themagnitude we nd here can create substantial nominal rigidityin other industries or markets In less competitive industries andmarkets menu costs of the type and magnitude we documenthere are likely to have a bigger impact on the frequency of priceadjustment and consequently on the degree of price rigidity

At a minimum the direct dollar measures of menu costs wereport here can be used as a starting point for future research onmeasuring their magnitude in other industries and establish-ments We anticipate that these menu costs will be similar inother markets which rely on posted prices (such as drugstoresdepartment stores etc) because the steps involved in the pricechange process are likely to be similar What may differ are thefrequency of price changes and the labor wage rates at thesestores For example since supermarket chains change thousandsof prices each week the total annual menu costs incurred bythese chains per store are likely to be high in comparison to otherretail formats such as chain drugstores or department storesThere are however a variety of industries for which the stepsinvolved in changing prices would be signicantly different fromthose reported in our study For example business-to-businesssales which often rely on a sales force will require changes in thelist price sheets changes in the instructions to the sales forcewhich may include education and discussion with the salespeoplein the company and so forth These business-to-business pricesalso often have more complex pricing schemes including quantitydiscounts bundling and individually negotiated prices As an-other example the composition of the cost of changing the news-stand prices of magazines [Cecchetti 1986] or the prices ofproducts sold through catalogs [Kashyap 1995] are different frommany of the menu cost components we discuss here Further thending that a centralization of pricing decisions makes the store-level managerial component of menu cost relatively small sug-gests that the managerial menu costs likely are highest insettings where price change decisions are decentralized Thus fu-ture empirical work should look at menu cost and its compositionin a variety of other industries markets and products with bothcentralized as well as decentralized price change decisions in or-der to see whether the magnitude of these costs can be general-ized and benchmarks can be established Further there aretechnological changes taking place in this and other industries

that promise to alter the structure of menu costs which deserveattention At the theoretical level our ndings suggest that it maybe worthwhile to explore models which incorporate the idea ofitem pricing laws as an additional component of menu costs

III2 Costs of Printing and Delivering New Price Tags

There are direct costs associated with printing and deliv-ering the price and sign tags The order must be recorded andprocessed at the chain sent to the printer recorded and pro-cessed at the printer printed packaged and then delivered toeach store The cost per tag is usually quite low $0017 per tagat Chain A which includes stock costs of $00118 per tag impres-sion and data center operator costs of $00037 per tag and mailroom handling costs of $00010 per tag There are however manyprice changes undertaken each week In total the costs of print-ing and delivering the price and sign tags range from $3048 to$10018 averaging $6014 per store per year (see Table III)These costs comprise less than 6 percent of the total menu costswe report

III3 Costs of Mistakes Made in the Process of Changing Prices

Despite the labor put into checking to make sure that theprice changes are done correctly there are still many price mis-takes that are not caught until customers discover them through-out the week and these mistakes impose costs on the chainClearly the costs associated with these errors must be consideredwhen deciding whether to change prices or not and therefore area relevant dimension of menu costs These mistakes can occur sooften that they were a feature of a Dateline segment on U Ssupermarket chains [NBC April 1992] and an article in MoneyMagazine [April 1993] Both the Money Magazine article andGoodstein [1994] report that on average 10 percent of the prod-ucts they examined had price mistakes A more recent study bythe Federal Trade Commission [1996] reports a total error rate ofabout 5 percent

The menu costs associated with these mistakes include lost

14 Our measure of labor cost may overstate the true costs of changing pricesif supermarkets hoard labor to save hiring and ring costs However this is notlikely to be the case for several reasons First the labor costs of changing priceswe report are based on actual measurements of the minimum amount of time andlabor required to accomplish the task rather than on the number of employeeshired to change prices at the store Second the adjustment in the amount of laboris usually done through hours worked which makes cost of hiring and ring lessrelevant And third the workers on the oor are routinely moved from task totask according to the need These tasks include stocking cleaning price changingcustomer service etc The workers employed by supermarket chains are alwaysbusy and so the opportunity cost of changing price is not zero Therefore laborhoarding is not likely to be an important factor in our measurements

cashier time to correct the errors scan guarantee refunds andinventory mistakes associated with incorrect price tags15 Lostcashier time is measured here in terms of wage payments Scanguarantee refunds are additional price reductions beyond the er-ror or additional items given away for free because of the mis-take Finally the inventory mistakes costs we report include onlythe cost of stockouts which occur when shelf price is lower thanintended

The mistake costs were available at Chains A C and D andthey range from $19135 to $20692 for an average of $20140 perstore annually (see Table III) These costs are the second largestcomponent of menu costs in our study comprising about 19 per-cent of the total

III4 Costs of In-Store Supervision Time Spent on ImplementingPrice Changes

Managers at the store level spend time overseeing imple-menting and troubleshooting the price change process OnlyChains A and B had a measure of the menu costs associated withthis in-store supervision time and both of these came from a self-reported number of hours spent on changing prices by the manag-ers at these chains The hours spent on changing prices were thesame across the chains approximately ve hours per week Thusthe menu costs for in-store supervision time came to $4241 and$6692 per store annually for Chains A and B respectively (seeTable III) These costs comprise less than 6 percent of the totalmenu costs we report in this paper However notice that thesemeasures do not include the cost of the management time spenton price change decisions made at corporate headquarters whichis discussed next

III5 Components of Menu Costs We Are Unable to Measure inDollar Terms

Our data set does not contain the exact dollar measures ofsome menu cost components One such component is the cost ofcorporate management time spent on price change decisions16 In

15 Other likely costs of price mistakes that we do not consider explicitlybecause we are unable to measure them in dollar terms are legal problems (whenthe scanner price is higher than the shelf price) loss in customer goodwill anddecreased protability (when the scanner price is lower than the shelf price)

16 It has been suggested that the cost of managerial decisions is one of themost important components of menu cost See for example Ball and Mankiw[1994] Kashyap [1995] and Meltzer [1995] Since the ESL system was not de-

THE MAGNITUDE OF MENU COSTS 807

the supermarket chains we study prices are generally set at cor-porate headquarters in a weekly meeting where the manager incharge of setting prices looks at a variety of information including(a) any manufacturer wholesale price changes promotions andother related issues (b) past sales for this product and (c) com-petitorsrsquo prices Based on this information and on discussionswith other managers the price-setting manager decides whetherto change prices and if so by how much

To estimate the magnitude of these managerial componentsof the menu costs consider the following In an average chainthere is at least one executive of merchandising who devotesmost of hisher time to pricing decisions In addition there areup to three senior managers who would deal with pricing andto whom category managers report There are also ten-to-twelvecategory managers who are responsible for setting prices on allthe products within their category An additional two-to-fourpeople spend full time handling the implementation of pricechanges across retail outlets coordinating the printing and deliv-ery of price tags and handling pricing problems in the systemAnother ve-to-seven workers gather the data on competitorsrsquoprices and analyse both the competitorsrsquo data and the storersquos ownscanner data to put it in a form useable by managers makingpricing decisions Thus in total there are about 21ndash27 peopleworking at the corporate headquarters on price change decisionsAssuming $150000 as the average annual salary of the executiveof merchandising and senior managers $100000 for categorymanagers and $50000 for the rest the chainwide managerialcost falls in the neighborhood of $23ndash$29 million a year whichseems a substantial amount However note that these pricing de-cision are made for the entire chain and therefore the costs perstore are signicantly less especially for the larger chains Forexample using $29 million as the upper bound the additionalannual menu cost per store for Chains AndashD which on averageoperate about 400 stores each averages about $7250 which ismuch lower than expected and is due to the centralization of theprice change decisions in the chains we study17

signed to save the costs of corporate headquarter managerial time spent on pricechange decisions the ESL company did not measure this component of menucosts The estimates reported in this section are based on the information receivedfrom the ESL company executives

17 A decentralization of the price change process say by allowing the store-level managers to make price change decisions can change these gures tremen-dously For example consider the following thought experiment conducted using

QUARTERLY JOURNAL OF ECONOMICS808

Our menu cost measures also do not include the cost ofchanging prices of direct store delivery (DSD) products Theseproducts are almost completely handled by manufacturers in-cluding stocking monitoring inventories and setting and chang-ing prices18 We have data on the weekly frequency of pricechanges of DSD products in Chain E In an average week thereare 174 price changes of DSD products which is about 10 percentof the supermarketrsquos total weekly price changes Using the costof changing the price of a regular product $133 (see Section IVfor details) the annual cost of changing prices of the DSD prod-ucts in this chain roughly equals $1203419 Our menu cost mea-sures do not include these gures since we do not have similardata for the other chains20

III6 Total Menu Costs

The total annual menu costs reported for each chain perstore are listed in the last row of Table III As the table indicatesthe menu costs range from $91416 to $114188 for an average of$105887 per store per year21 Note that these menu cost mea-

the average annual per store gures for Chains AndashD Suppose that the supermar-ket chains decentralize the price change process by hiring for each store only one-quarter of the price change managing team while at the same time they com-pletely eliminate the corporate level team The resulting annual menu cost perstore would be $830887 ( 5 $105887 1 $725000) which would dwarf any of themeasurable menu cost gures we report in this study Even if the average storeonly hired just the merchandising manager at the annual cost of $150000 itwould still incur annual managerial cost of about $255887 ( 5 $105887 1$150000) In other words such a trivial decentralization would double the store-level menu costs This would indeed make the cost of price change decisions themost important component of menu cost

18 DSD products usually are high-volume fast-moving or perishable prod-ucts such as milk soda eggs bread dairy snacks etc In the chains we studyabout 10ndash20 percent of the products are of a DSD type but that share may reachas much as 40 percent of the products carried [Direct Store Delivery Work Groupet al 1995]

19 The process of changing prices of DSD and of regular products is similarBut with DSD products there are additional costs of the time spent on driving tothe store parking and setting up the price change process at each store

20 Our measures of menu cost also do not incorporate the cost of informingconsumers about price changes which can take a variety of forms such as newspa-per ads and inserts TV and radio ads in-store promotion signs etc Finally wehave no data on lost customer goodwill and damaged reputation caused by dis-crepancies between price tag and cash register [Okun 1981 Carlton and Perloff1994 Haddock and McChesney 1994]

21 The variation in the menu costs across the chains is mostly due to wagerate and labor-efciency variations Also note that since the supermarket chainsin our sample are similar in the size of their stores carry similar sets of productsand follow similar processes of price change and price change decisions it is rea-sonable to believe that the chains incur similar types of costs Therefore as notedunderneath Table III these menu cost measures are computed by replacing theunreported gures by the averages of the available values from the other chains

IV ITEM PRICING LAWS AND MENU COSTS

In this section we provide evidence on the menu costs for anadditional chain (Chain E) which unlike the other four chainsoperates in a state with an item pricing law The most importantaspect of item pricing laws is that they require a price tag on eachindividual item sold not just on the shelf which is what the otherfour chains in our sample do For example the item pricing lawin Connecticut requires that the grocers ldquoshall mark or cause tobe marked each consumer commodity which bears a UniversalProduct Code with its retail pricerdquo 22 From a menu cost perspec-tive the requirement of posting prices on every item (in additionto the shelf price tag) introduces additional costs in the processof changing prices

Although most of the steps involved in changing prices arethe same for both types of chains stores that are subject to itempricing laws have to undertake additional steps to obey this law23

The labor cost component of menu costs in Chain E totals $75127a year of which $49710 is the cost of the labor time spent onchanging the prices of individual items $3234 is the cost of thelabor time spent on shelf tag replacements and $22183 is thecost of the labor time spent on sign changes (see Table III)24 Anadditional $44168 is spent annually putting prices on new itemsas they are brought to the shelves Although we do not includethis last gure in our menu cost measures because we do not haveinformation on how much of it is due to price change activity andhow much due to just pricingmdashthese costs are clearly a directconsequence of the item pricing law The printing and deliverycost of price tags and price signs are $7644 and the mistake

22 Public Act No 75ndash391 An Act Concerning Pricing of Consumer Merchan-dise [Public Acts of the State of Connecticut 1975 Vol 1 p 390]

23 These steps which are in addition to the regular steps undertaken toreplace price tags on the shelves include (1) obtaining item price tags (2) settingup workstations (3) locating the product (4) removing an item from the shelf (5)removing old price tag (6) setting marking gun (7) applying new price tag and(8) returning the item back to the shelf

24 Since we do not have a measure of the cost of labor time spent on signchanges and the cost of in-store managerial supervision time for this chain weuse the average of the chains that report them (A and D) Note also that thehourly wage rate of $907 paid by Chain E is lower than the hourly wage of about$1400ndash$2000 paid by Chains AndashD

QUARTERLY JOURNAL OF ECONOMICS810

25 Further note that the chains with smaller menu costs are likely tochange their prices more frequently which suggests that the gures of the totalannual menu costs understate the differences between Chain E and the otherchains Indeed despite the large difference in the menu cost per price change thetotal annual menu costs per store for Chain E ($109036) are more comparable tothose of Chains AndashD ($105887)

26 In calculations that follow we use industry averages because (1) thechains did not share this proprietary information with us and (2) we were re-quired to keep the identity of these chains condential as some of these numbersare detailed enough to enable some readers to identify the chains under study

costs are $20799 These gures along with the amount of $5466for the cost of in-store managerial supervision time yield totalannual menu costs of $109036 per store

Although the magnitude of the total annual menu costs seemsimilar to the other four chains note that the average weeklyfrequency of price changes in Chain E is only 1578 which is only403 ( 5 15783916) percent of the price changes made by theother four chains Thus the average menu cost per price changefor Chain E is $133 (see Table IV last row) In contrast the corre-sponding gures for Chains AndashD average $052 Hence the menucosts per price change incurred by the supermarket chain facingitem pricing laws are more than two and a half times the amountincurred by chains that are not subject to this law25 Overallthese ndings suggest that legal restrictions of the type of itempricing laws can have a signicant impact on the menu costs in-curred by sellers

V SIGNIFICANCE OF THE MENU COSTS

The next natural question to ask is how important are thesecosts To address this question we (1) provide several relativemeasures of the menu costs (2) discuss the effect of the menucosts on supermarketsrsquo price change activity and (3) discuss mac-roeconomic implications by relating our ndings to the existingtheoretical models of menu costs In each case we provide addi-tional evidence to help assess the importance of these menu costs

V1 Relative Measures of the Menu Costs

In order to assess the relative magnitude of the menu costsreported in Section IV we now present the menu cost gures rela-tive to the average store-level revenues and net prot margins26

In addition we present the menu cost gures per price changeThe annual average revenues of a large U S supermarket

chain of the type and size included in our sample is $15052716

per store27 According to the second row of Table IV the ratio ofmenu costs to revenues for Chains AndashD ranges between 061ndash076percent averaging 070 percent28 We relate the size of thesegures to the existing theoretical menu cost models in sub-section V3

Net prot margin which measures the revenues minus allcosts is approximately 1ndash3 percent of revenues for these chains[Montgomery 1994] so we use 2 percent as a working averageThe reason for the low prot rate in this industry is the intensecompetition [Calatone et al 1989] especially at the regional level[Chevalier 1995] which has been increasing since the early 1990s[Progressive Grocer November 1992 p 50] It follows that theaverage store protability for these chains equals $301054 peryear Therefore the ratio of total menu cost to net margin forChains AndashD ranges between 304ndash379 percent for an average of352 percent Thus the menu costs we report in this study repre-sent a signicant share of supermarketsrsquo prots

Another way to look at the menu cost gures we report is toexpress them relative to the frequency of price changes In thelast row of Table IV we present the menu cost gures per pricechange for each chain As the table indicates the cost of changinga price in Chains AndashD ranges between $046ndash$068 for an averageof $052 For Chain E the gure is substantially larger $133 perprice change29 These gures are lower than the estimated cost of

27 This is the average of two different estimates $12945432 and$17160000 The source of the rst gure is internal record of a supermarketchain of the type and size studied here The second gure comes from Supermar-ket Business [1993 p 52]

28 We also measured the menu costs in terms of controllable operating ex-penses (which are the portion of costs that the retailer has direct control over andtherefore are often the costs that the retailer is most focused on managing) andgross margins (which measure the supermarket revenues minus direct cost of theproducts it sells) We nd that the menu costs comprise 313 percent of controlla-ble operating expenses and 281 percent of gross margins at these chains on aver-age Finally if we measure the menu costs relative to the number of productscarried per store (about 25000) then we nd that the menu costs per productaverage $423 for Chains AndashD See Table IV and its footnotes for details

29 We can also try to express the menu cost gures relative to the numberof individual items sold by these chains each year (Note the difference betweennumber of products carried and number of items sold As an example a TartarControl Crest 8oz would be considered a product carried and 300 units of themsold per year would be considered number of items sold) Using $170 as the aver-age price of all the products sold we nd that the menu cost per item sold for thefour chains is in the range of $00103ndash$00129 for an average of $00119 (see TableIV second to last row) To see the relative magnitude of these gures note thataccording to Berkowitz Kerin and Rudelius [1986 p 319] the goal of the super-market chains of the type we study ldquo is to make 1 penny of prot on each dollarof salesrdquo Thus menu cost per item sold when adjusted for the average price

THE MAGNITUDE OF MENU COSTS 813

$200ndash$300 per price change reported by Slade [1996a] Thereare several possible reasons for this (1) our menu cost gures arebased on actual measurements of the resources that go into theprice change process whereas she estimates menu costs econo-metrically as model coefcients using a mix of store-level priceand aggregate cost data (2) we cover 25000 products that thesupermarkets carry rather than a single product category (3) ourmenu cost gures do not include all components of menu costsand (4) there could be differences in wage rates that may be im-portant given the signicance of the labor cost component inmenu costs

V2 The Effect of Menu Costs on the Price Change Activity of theSupermarkets

In this section we present evidence which suggests that thesemenu costs may be forming a barrier to price change activity Tobegin with consider the effect of the item pricing law on the pricechange activity of Chain E The data on the weekly frequency ofprice changes in each chain are displayed in the last two rows ofTable I According to these gures the average weekly frequencyof price changes in Chain E is only 1578 Thus on average ChainE changes the prices of only 631 percent of its products eachweek In contrast the average weekly frequency of price changesat Chains AndashD ranges from 3223 to 4316 for the four-chain aver-age of 3916 price changes weekly So Chains AndashD change priceson 1289 to 1726 percent of their products each week yielding afour-chain average of 1566 percent Thus Chain E which facesthe item pricing law changes prices only about one-third timesas frequently as do Chains AndashD30

Moreover within Chain E there are 400 products that areexempt from the item pricing law and thereby face lower menucosts We nd that there are an average of 83 weekly pricechanges for these products yielding 21 percent of these productschanging prices So within Chain E they change prices over threetimes as frequently for products with lower menu costs than for

roughly equals one-half of their target net prot per item which seemssubstantial

30 However note that our comparison of the two types of chains may not becompletely ceteris paribus because these stores are located in different states andtherefore there may be other chain-specic factors (in addition to item pricinglaws) that distinguish these stores We do not have any specic information onthese differences We do know however that the stores in these chains are similarin size and carry similar sets of products

QUARTERLY JOURNAL OF ECONOMICS814

the products with higher menu costs Note that this nding is onthe price change activity within the same chain offering almost anatural experiment on the impact of menu costs on the chainrsquospricing behavior Hence we provide evidence both across chainsas well as across products within a chain that as the costs ofchanging price go up the frequency of price changes goes downThus the menu costs we nd are signicant enough to affect thechainrsquos price change practice

We also have additional evidence from Chains A B and Dabout these menu costs being a barrier to certain price changesand it is summarized in Table V According to the Price Manage-ment Department of Chain A the chain experiences cost in-creases on 860 products in an average week to which it wouldlike to react with a price increase31 However on average 22 per-cent of these price increases are not implemented immediatelybecause the cost of changing prices for these products is too highto make it economically worthwhile Figures of the same magni-tude were reported by other chains For example Chain D experi-ences cost increases for 961 products in an average week Out ofthese the chain adjusts prices of only 633 products The re-maining 34 percent of the prices are left unadjusted because ofthe menu costs Similarly Chain B nds it economically ineffi-cient to adjust prices of 508 ie 30 percent of its products eachweek because of menu costs This provides additional evidencethat the menu costs incurred by these chains are preventing priceadjustments to some costs changes leading to price rigidities ofthe products involved32 Note that although we do not have simi-lar data for Chain E we would expect signicantly lower num-bers on this measure at that chain These gures also suggest anupper bound on the benet of complete price exibility under thecurrent pricing practice of weekly price adjustments Howeverif new technologies (eg ESL systems) and new pricing prac-tices (eg a decentralization of the price change decisions) are

31 Our data contain information only on the frequency of cost increasesAlthough it is more than likely that the supermarkets are experiencing cost de-creases as well our data set contained no information on such decreases

32 Menu costs may even be playing a role in the observed movement towardpricing strategies that rely on fewer price changes such as EDLP [Blattberg andNeslin 1989 Lattin and Ortmeyer 1991 Marketing News April 13 1992 p 8]According to Progressive Grocer [November 1992 p 50] ldquoA growing number ofoperators say they have switched from high-low pricing [to EDLP] They cite theinefciencies of making frequent price changes rdquo Similarly Hoch Dreze andPurk [1994 p 16] state that EDLP lowers operating costs by lowering ldquo in-store labor costs because of less frequent changeovers in special displaysrdquo

adopted allowing a fundamental change in the way the pricingmechanism is currently set the managers could consider morefrequent price change activity (eg multiple times each week) asmenu costs go down

In this paper we measure the menu costs at the chainsrsquo cur-rent level of price change activity It may be worthwhile to specu-late on the shape of the cost function relating menu costs to thefrequency of price changes by assessing how these costs wouldchange if the price change activity were to increase or to decreaseIt seems likely that many of the costs we report in this paper will(approximately) change linearly with additional price changeswithin the current range of price changes the chains are under-taking (plus or minus perhaps a thousand per week) For ex-ample the labor costs associated with changing a shelf price tagcosts of verifying price changes and the costs of mistakes oc-curring during this process all increase linearly with the fre-quency of price changes This is because most of the time-consuming steps involved in the price change process must berepeated each time an additional shelf price tag is changed (seeTable II) Further we were unable to nd many tasks that gener-ated signicant returns to scale It is unclear what cost savingsare available if the price change activity drops substantially be-

QUARTERLY JOURNAL OF ECONOMICS816

low the levels it is at now Clearly if price changes were nearzero or done less frequently than weekly (say monthly) therecould be major differences in these costs

What is less clear is how these costs would change at moreextreme levels of price change activity With less frequent pricechanges the menu costs could probably be reduced signicantlyalthough the cost of deciding what prices to set initially and thecost of putting the initial shelf price tags would still remain as alower bound of the menu cost However for achieving more priceexibility by changing prices more frequently (ie multiple timeseach week) substantial changes must be undertaken At presentthe supermarket chains are set up to make the majority of theirprice changes on a weekly basis with the appropriate systems inplace to make this process most efcient For example in orderto save costs and to have higher quality price tags (eg withcolor more details greater clarity glossy etc) the chains oftensend new price tag requests to a printing shop which takes threedays to print and deliver the labels to each store Then giventhe large number of price changes taking place and the goals ofminimizing customer disruptions and labor costs (such as over-time pay) and coordinating with advertised price promotions theprices are changed in the store over a two-to-three-day period (seeTable VI) The combination of these schedule and built-in lags isacceptable under the current practice of changing prices weeklybut would have to be adjusted dramatically to allow for signifi-cantly more frequent price changes on a regular basis

Perhaps even more imposing are the costs of changing themanagerial costs associated with the current weekly system ofprice changes The process of pricing at this organizational levelis not a self-contained activity taking place in isolation from otheroperations of the supermarket management Rather it is a partof a larger system of business decisions and operations The cur-rent process of operations (such as data collection and theiranalysis management meetings coordination of the decisionsacross functional areas etc) is set up to function on a weeklybasis33 Further these management accounting and logisticssystems are currently built around a tremendous amount of in-

34 For example under the current system a chainwide category manageroperating at the corporate headquarters needs to study and assess numerouspieces of detailed information such as competitorsrsquo price and sale information fromthe last week the past weekrsquos sales at the own chain manufacturersupplier pro-motions wholesale price reductions coop allowances new product offerings shelfspace decisions coordination with newspaper advertising logistics at the ware-houses as well as at each store store differences in terms of customer characteris-tics and competitive environments productshelf selection and layout etc

35 If the supermarket chains indeed restructure the entire price change pro-cess and begin to change prices much more frequently (say two-to-three times aweek) on a regular basis then the shape of this cost function could change in anunpredictable way

V3 Relating Our Findings to the Existing Theoretical Models ofMenu Costs

In order to assess the magnitude of these menu cost guresin the context of the existing theoretical menu cost literatureconsider the following calculation experiments done within theframework of two theoretical menu cost models Blanchard andKiyotaki [1987] study a general equilibrium menu cost modelwith monopolistic competition and with unit elasticity of aggre-gate demand with respect to real money balances According totheir calculations menu costs of the magnitude of 008 percent ofrevenues which they consider ldquovery smallrdquo may be sufcient toprevent adjustment of prices Ball and Romer [1990] conductsimilar calculations in the framework of a model with imperfectcompetition and menu costs They nd that for plausible markupand labor elasticity parameter values menu costs needed to pre-vent price adjustment are 070 percent of revenues which as theysuggest are nonnegligible For smaller menu costs eg 004 per-cent of the revenue which Ball and Romer consider ldquotrivialrdquo im-plausibly large values of markup and labor elasticity parametersare needed to prevent price adjustment to monetary shocks

According to the gures in Table IV the reported menu costto revenues ratio for Chains AndashD averages 070 percent rangingfrom 061 percent to 076 percent These are signicantly largerthan the ldquotrivialrdquo 004 or 008 percent gures mentioned abovesuggesting that the menu cost gures we nd here are nontrivialFurther under the model and parameter values considered byBlanchard and Kiyotaki [1987] the menu cost gures we nd arehigher than the theoretical minimum needed to form a barrier toprice adjustments Under the model and parameter values con-sidered by Ball and Romer [1990] the reported menu costreve-nue ratio for all but one chain reaches or crosses the theoreticalthreshold of 070 needed to form a barrier to price adjustmentsThe existence of numerous unmeasured menu cost componentsdiscussed in subsection III5 also raises the possibility that theactual menu costs incurred by these chains are signicantlyhigher than that threshold This suggests that the menu costs wereport may be large enough to form a barrier to nominal priceadjustments when interpreted in the context of these models

An issue of interest in this literature is time-dependent ver-sus state-dependent pricing rules (see for example Caplin andLeahy [1991]) The evidence from our data set on the timing of

THE MAGNITUDE OF MENU COSTS 819

price changes suggests that the price change decisions in thesesupermarkets have a strong time-dependent price-setting ele-ment36 For example according to Table VI the prices in Chain Aare changed weekly according to the following schedule the pricechanges of general merchandise that is advertised is done Satur-day nights grocery and produce prices are changed Sundaynights the rest of the general merchandise prices are changed onMonday nights and the prices of advertised grocery items arechanged on Tuesday nights Thus as the gures in Table VI indi-cate over 96 percent of the price changes are done during Sundayand Monday nights However this does not imply that state-dependent pricing rules are unimportant Even if price changesacross product categories follow a prescheduled weekly time ta-ble the prices of which products to change is likely to be a state-dependent decision For example it could depend on changes insupply and demand conditions such as competitorsrsquo price changedecisions Indeed Levy Dutta and Bergen [1996] use retailstore-level orange juice price and cost data to demonstrate thatthe extent of price response to cost shocks that is the extent ofprice rigidity may depend on the nature of supply shocks37

We do not want to overstate the usefulness of our data fordirectly addressing the issue of monetary nonneutrality On onehand authors such as Caplin and Spulber [1987] have demon-strated that under certain conditions individual price rigiditymay not be sufcient for aggregate price rigidity but unfortu-nately our data do not speak directly to this issue38 On the otherhand authors such as Akerlof and Yellen [1985] Mankiw [1985]Parkin [1986] and Caplin and Leahy [1997] have shown that even

36 Danziger [1983] Caballero [1989] and Ball and Mankiw [1994] suggestthat time-dependent price adjustment of the type documented here can be optimalif the cost of gathering information about the state exceeds the cost of making theprice adjustment itself

37 We also considered the possibility of convexities in the cost of changingprices Our data do not suggest many convexities since the labor time spent inthe price tag change process the cost of printing and delivering price tags andin-store supervision time do not change with the size of a price change The onlymeasurable component of menu costs that could be convex is the cost of mistakesmade the larger the price change the higher the probability of a customer notic-ing the mistake and the larger the amount required to be refunded as compensa-tion Among the unmeasured components of menu cost the cost of corporatemanagerial time may increase with the size of a price change because larger pricechanges may require more serious consideration

38 Also see Balke and Wynne [1996] and Bryan and Cecchetti [1996] Sincewe do not have measures of how menu costs change over time our data also havelittle to say about time variation in menu costs or about the relationship betweenmenu costs and ination which during the period of the data collection (1991ndash1992) averaged about 3 percent annually

small menu costs can be relevant since they may be sufcient togenerate substantial aggregate nominal rigidity and thus largebusiness cycles Therefore as Blinder [1994] Kashyap [1995]and Slade [1996a] emphasize it is important to search for directevidence that such costs are indeed present at the micro level Bydirectly identifying documenting and measuring the magnitudeof menu costs at the store level we are taking an important stepin that direction

VI CONCLUSION AND FUTURE RESEARCH

Our main contribution is that we provide direct microeco-nomic evidence on the actual magnitude of menu costs for fourlarge U S retail supermarket chains The annual menu costs perstore at these chains average $105887 comprising 070 percentof revenues 352 percent of net prot margins and $052 perprice change on average

Further we provide evidence which suggests that thesemenu costs may be forming a barrier to price changes Specifi-cally we show that (1) supermarket chains not subject to itempricing law change prices two and a half times more frequentlythan the chain that is subject to the law (2) within the chain thatis subject to the item pricing law they change prices over threetimes as frequently for products that are exempt from this lawthan for the products which are subject to this law and (3) wend that these chains do not adjust prices of up to one-third ofthe products for which they face cost increases because of menucost considerations

When we relate these ndings to the existing theoreticalmodels of menu costs we conclude that the magnitude of menucosts we nd is large enough to be capable of having macroeco-nomic signicance Specically when considered in the context ofthe theoretical menu cost models of Blanchard and Kiyotaki[1987] and Ball and Romer [1990] we nd that the menu costgures we report are ldquonontrivialrdquo and their relative magnitudescross the minimum theoretical threshold needed to form a barrierto price adjustments

Despite the high relative magnitude of the marginal cost ofchanging price that we found the data still indicate frequentweekly price changes This is because of the high marginal bene-t of changing price which is due to the erce competition foundin the retail supermarket industry That marginal benets may

outweigh the marginal costs of changing prices in this industryhowever does not rule out the possibility that menu costs of themagnitude we nd here can create substantial nominal rigidityin other industries or markets In less competitive industries andmarkets menu costs of the type and magnitude we documenthere are likely to have a bigger impact on the frequency of priceadjustment and consequently on the degree of price rigidity

At a minimum the direct dollar measures of menu costs wereport here can be used as a starting point for future research onmeasuring their magnitude in other industries and establish-ments We anticipate that these menu costs will be similar inother markets which rely on posted prices (such as drugstoresdepartment stores etc) because the steps involved in the pricechange process are likely to be similar What may differ are thefrequency of price changes and the labor wage rates at thesestores For example since supermarket chains change thousandsof prices each week the total annual menu costs incurred bythese chains per store are likely to be high in comparison to otherretail formats such as chain drugstores or department storesThere are however a variety of industries for which the stepsinvolved in changing prices would be signicantly different fromthose reported in our study For example business-to-businesssales which often rely on a sales force will require changes in thelist price sheets changes in the instructions to the sales forcewhich may include education and discussion with the salespeoplein the company and so forth These business-to-business pricesalso often have more complex pricing schemes including quantitydiscounts bundling and individually negotiated prices As an-other example the composition of the cost of changing the news-stand prices of magazines [Cecchetti 1986] or the prices ofproducts sold through catalogs [Kashyap 1995] are different frommany of the menu cost components we discuss here Further thending that a centralization of pricing decisions makes the store-level managerial component of menu cost relatively small sug-gests that the managerial menu costs likely are highest insettings where price change decisions are decentralized Thus fu-ture empirical work should look at menu cost and its compositionin a variety of other industries markets and products with bothcentralized as well as decentralized price change decisions in or-der to see whether the magnitude of these costs can be general-ized and benchmarks can be established Further there aretechnological changes taking place in this and other industries

that promise to alter the structure of menu costs which deserveattention At the theoretical level our ndings suggest that it maybe worthwhile to explore models which incorporate the idea ofitem pricing laws as an additional component of menu costs

III2 Costs of Printing and Delivering New Price Tags

There are direct costs associated with printing and deliv-ering the price and sign tags The order must be recorded andprocessed at the chain sent to the printer recorded and pro-cessed at the printer printed packaged and then delivered toeach store The cost per tag is usually quite low $0017 per tagat Chain A which includes stock costs of $00118 per tag impres-sion and data center operator costs of $00037 per tag and mailroom handling costs of $00010 per tag There are however manyprice changes undertaken each week In total the costs of print-ing and delivering the price and sign tags range from $3048 to$10018 averaging $6014 per store per year (see Table III)These costs comprise less than 6 percent of the total menu costswe report

III3 Costs of Mistakes Made in the Process of Changing Prices

Despite the labor put into checking to make sure that theprice changes are done correctly there are still many price mis-takes that are not caught until customers discover them through-out the week and these mistakes impose costs on the chainClearly the costs associated with these errors must be consideredwhen deciding whether to change prices or not and therefore area relevant dimension of menu costs These mistakes can occur sooften that they were a feature of a Dateline segment on U Ssupermarket chains [NBC April 1992] and an article in MoneyMagazine [April 1993] Both the Money Magazine article andGoodstein [1994] report that on average 10 percent of the prod-ucts they examined had price mistakes A more recent study bythe Federal Trade Commission [1996] reports a total error rate ofabout 5 percent

The menu costs associated with these mistakes include lost

14 Our measure of labor cost may overstate the true costs of changing pricesif supermarkets hoard labor to save hiring and ring costs However this is notlikely to be the case for several reasons First the labor costs of changing priceswe report are based on actual measurements of the minimum amount of time andlabor required to accomplish the task rather than on the number of employeeshired to change prices at the store Second the adjustment in the amount of laboris usually done through hours worked which makes cost of hiring and ring lessrelevant And third the workers on the oor are routinely moved from task totask according to the need These tasks include stocking cleaning price changingcustomer service etc The workers employed by supermarket chains are alwaysbusy and so the opportunity cost of changing price is not zero Therefore laborhoarding is not likely to be an important factor in our measurements

QUARTERLY JOURNAL OF ECONOMICS806

cashier time to correct the errors scan guarantee refunds andinventory mistakes associated with incorrect price tags15 Lostcashier time is measured here in terms of wage payments Scanguarantee refunds are additional price reductions beyond the er-ror or additional items given away for free because of the mis-take Finally the inventory mistakes costs we report include onlythe cost of stockouts which occur when shelf price is lower thanintended

The mistake costs were available at Chains A C and D andthey range from $19135 to $20692 for an average of $20140 perstore annually (see Table III) These costs are the second largestcomponent of menu costs in our study comprising about 19 per-cent of the total

III4 Costs of In-Store Supervision Time Spent on ImplementingPrice Changes

Managers at the store level spend time overseeing imple-menting and troubleshooting the price change process OnlyChains A and B had a measure of the menu costs associated withthis in-store supervision time and both of these came from a self-reported number of hours spent on changing prices by the manag-ers at these chains The hours spent on changing prices were thesame across the chains approximately ve hours per week Thusthe menu costs for in-store supervision time came to $4241 and$6692 per store annually for Chains A and B respectively (seeTable III) These costs comprise less than 6 percent of the totalmenu costs we report in this paper However notice that thesemeasures do not include the cost of the management time spenton price change decisions made at corporate headquarters whichis discussed next

III5 Components of Menu Costs We Are Unable to Measure inDollar Terms

Our data set does not contain the exact dollar measures ofsome menu cost components One such component is the cost ofcorporate management time spent on price change decisions16 In

15 Other likely costs of price mistakes that we do not consider explicitlybecause we are unable to measure them in dollar terms are legal problems (whenthe scanner price is higher than the shelf price) loss in customer goodwill anddecreased protability (when the scanner price is lower than the shelf price)

16 It has been suggested that the cost of managerial decisions is one of themost important components of menu cost See for example Ball and Mankiw[1994] Kashyap [1995] and Meltzer [1995] Since the ESL system was not de-

THE MAGNITUDE OF MENU COSTS 807

the supermarket chains we study prices are generally set at cor-porate headquarters in a weekly meeting where the manager incharge of setting prices looks at a variety of information including(a) any manufacturer wholesale price changes promotions andother related issues (b) past sales for this product and (c) com-petitorsrsquo prices Based on this information and on discussionswith other managers the price-setting manager decides whetherto change prices and if so by how much

To estimate the magnitude of these managerial componentsof the menu costs consider the following In an average chainthere is at least one executive of merchandising who devotesmost of hisher time to pricing decisions In addition there areup to three senior managers who would deal with pricing andto whom category managers report There are also ten-to-twelvecategory managers who are responsible for setting prices on allthe products within their category An additional two-to-fourpeople spend full time handling the implementation of pricechanges across retail outlets coordinating the printing and deliv-ery of price tags and handling pricing problems in the systemAnother ve-to-seven workers gather the data on competitorsrsquoprices and analyse both the competitorsrsquo data and the storersquos ownscanner data to put it in a form useable by managers makingpricing decisions Thus in total there are about 21ndash27 peopleworking at the corporate headquarters on price change decisionsAssuming $150000 as the average annual salary of the executiveof merchandising and senior managers $100000 for categorymanagers and $50000 for the rest the chainwide managerialcost falls in the neighborhood of $23ndash$29 million a year whichseems a substantial amount However note that these pricing de-cision are made for the entire chain and therefore the costs perstore are signicantly less especially for the larger chains Forexample using $29 million as the upper bound the additionalannual menu cost per store for Chains AndashD which on averageoperate about 400 stores each averages about $7250 which ismuch lower than expected and is due to the centralization of theprice change decisions in the chains we study17

signed to save the costs of corporate headquarter managerial time spent on pricechange decisions the ESL company did not measure this component of menucosts The estimates reported in this section are based on the information receivedfrom the ESL company executives

17 A decentralization of the price change process say by allowing the store-level managers to make price change decisions can change these gures tremen-dously For example consider the following thought experiment conducted using

QUARTERLY JOURNAL OF ECONOMICS808

Our menu cost measures also do not include the cost ofchanging prices of direct store delivery (DSD) products Theseproducts are almost completely handled by manufacturers in-cluding stocking monitoring inventories and setting and chang-ing prices18 We have data on the weekly frequency of pricechanges of DSD products in Chain E In an average week thereare 174 price changes of DSD products which is about 10 percentof the supermarketrsquos total weekly price changes Using the costof changing the price of a regular product $133 (see Section IVfor details) the annual cost of changing prices of the DSD prod-ucts in this chain roughly equals $1203419 Our menu cost mea-sures do not include these gures since we do not have similardata for the other chains20

III6 Total Menu Costs

The total annual menu costs reported for each chain perstore are listed in the last row of Table III As the table indicatesthe menu costs range from $91416 to $114188 for an average of$105887 per store per year21 Note that these menu cost mea-

the average annual per store gures for Chains AndashD Suppose that the supermar-ket chains decentralize the price change process by hiring for each store only one-quarter of the price change managing team while at the same time they com-pletely eliminate the corporate level team The resulting annual menu cost perstore would be $830887 ( 5 $105887 1 $725000) which would dwarf any of themeasurable menu cost gures we report in this study Even if the average storeonly hired just the merchandising manager at the annual cost of $150000 itwould still incur annual managerial cost of about $255887 ( 5 $105887 1$150000) In other words such a trivial decentralization would double the store-level menu costs This would indeed make the cost of price change decisions themost important component of menu cost

18 DSD products usually are high-volume fast-moving or perishable prod-ucts such as milk soda eggs bread dairy snacks etc In the chains we studyabout 10ndash20 percent of the products are of a DSD type but that share may reachas much as 40 percent of the products carried [Direct Store Delivery Work Groupet al 1995]

19 The process of changing prices of DSD and of regular products is similarBut with DSD products there are additional costs of the time spent on driving tothe store parking and setting up the price change process at each store

20 Our measures of menu cost also do not incorporate the cost of informingconsumers about price changes which can take a variety of forms such as newspa-per ads and inserts TV and radio ads in-store promotion signs etc Finally wehave no data on lost customer goodwill and damaged reputation caused by dis-crepancies between price tag and cash register [Okun 1981 Carlton and Perloff1994 Haddock and McChesney 1994]

21 The variation in the menu costs across the chains is mostly due to wagerate and labor-efciency variations Also note that since the supermarket chainsin our sample are similar in the size of their stores carry similar sets of productsand follow similar processes of price change and price change decisions it is rea-sonable to believe that the chains incur similar types of costs Therefore as notedunderneath Table III these menu cost measures are computed by replacing theunreported gures by the averages of the available values from the other chains

THE MAGNITUDE OF MENU COSTS 809

sures include only the components we could accurately measurein dollar terms which are discussed in subsections III1ndashIII4

IV ITEM PRICING LAWS AND MENU COSTS

In this section we provide evidence on the menu costs for anadditional chain (Chain E) which unlike the other four chainsoperates in a state with an item pricing law The most importantaspect of item pricing laws is that they require a price tag on eachindividual item sold not just on the shelf which is what the otherfour chains in our sample do For example the item pricing lawin Connecticut requires that the grocers ldquoshall mark or cause tobe marked each consumer commodity which bears a UniversalProduct Code with its retail pricerdquo 22 From a menu cost perspec-tive the requirement of posting prices on every item (in additionto the shelf price tag) introduces additional costs in the processof changing prices

Although most of the steps involved in changing prices arethe same for both types of chains stores that are subject to itempricing laws have to undertake additional steps to obey this law23

The labor cost component of menu costs in Chain E totals $75127a year of which $49710 is the cost of the labor time spent onchanging the prices of individual items $3234 is the cost of thelabor time spent on shelf tag replacements and $22183 is thecost of the labor time spent on sign changes (see Table III)24 Anadditional $44168 is spent annually putting prices on new itemsas they are brought to the shelves Although we do not includethis last gure in our menu cost measures because we do not haveinformation on how much of it is due to price change activity andhow much due to just pricingmdashthese costs are clearly a directconsequence of the item pricing law The printing and deliverycost of price tags and price signs are $7644 and the mistake

22 Public Act No 75ndash391 An Act Concerning Pricing of Consumer Merchan-dise [Public Acts of the State of Connecticut 1975 Vol 1 p 390]

23 These steps which are in addition to the regular steps undertaken toreplace price tags on the shelves include (1) obtaining item price tags (2) settingup workstations (3) locating the product (4) removing an item from the shelf (5)removing old price tag (6) setting marking gun (7) applying new price tag and(8) returning the item back to the shelf

24 Since we do not have a measure of the cost of labor time spent on signchanges and the cost of in-store managerial supervision time for this chain weuse the average of the chains that report them (A and D) Note also that thehourly wage rate of $907 paid by Chain E is lower than the hourly wage of about$1400ndash$2000 paid by Chains AndashD

QUARTERLY JOURNAL OF ECONOMICS810

25 Further note that the chains with smaller menu costs are likely tochange their prices more frequently which suggests that the gures of the totalannual menu costs understate the differences between Chain E and the otherchains Indeed despite the large difference in the menu cost per price change thetotal annual menu costs per store for Chain E ($109036) are more comparable tothose of Chains AndashD ($105887)

26 In calculations that follow we use industry averages because (1) thechains did not share this proprietary information with us and (2) we were re-quired to keep the identity of these chains condential as some of these numbersare detailed enough to enable some readers to identify the chains under study

costs are $20799 These gures along with the amount of $5466for the cost of in-store managerial supervision time yield totalannual menu costs of $109036 per store

Although the magnitude of the total annual menu costs seemsimilar to the other four chains note that the average weeklyfrequency of price changes in Chain E is only 1578 which is only403 ( 5 15783916) percent of the price changes made by theother four chains Thus the average menu cost per price changefor Chain E is $133 (see Table IV last row) In contrast the corre-sponding gures for Chains AndashD average $052 Hence the menucosts per price change incurred by the supermarket chain facingitem pricing laws are more than two and a half times the amountincurred by chains that are not subject to this law25 Overallthese ndings suggest that legal restrictions of the type of itempricing laws can have a signicant impact on the menu costs in-curred by sellers

V SIGNIFICANCE OF THE MENU COSTS

The next natural question to ask is how important are thesecosts To address this question we (1) provide several relativemeasures of the menu costs (2) discuss the effect of the menucosts on supermarketsrsquo price change activity and (3) discuss mac-roeconomic implications by relating our ndings to the existingtheoretical models of menu costs In each case we provide addi-tional evidence to help assess the importance of these menu costs

V1 Relative Measures of the Menu Costs

In order to assess the relative magnitude of the menu costsreported in Section IV we now present the menu cost gures rela-tive to the average store-level revenues and net prot margins26

In addition we present the menu cost gures per price changeThe annual average revenues of a large U S supermarket

chain of the type and size included in our sample is $15052716

per store27 According to the second row of Table IV the ratio ofmenu costs to revenues for Chains AndashD ranges between 061ndash076percent averaging 070 percent28 We relate the size of thesegures to the existing theoretical menu cost models in sub-section V3

Net prot margin which measures the revenues minus allcosts is approximately 1ndash3 percent of revenues for these chains[Montgomery 1994] so we use 2 percent as a working averageThe reason for the low prot rate in this industry is the intensecompetition [Calatone et al 1989] especially at the regional level[Chevalier 1995] which has been increasing since the early 1990s[Progressive Grocer November 1992 p 50] It follows that theaverage store protability for these chains equals $301054 peryear Therefore the ratio of total menu cost to net margin forChains AndashD ranges between 304ndash379 percent for an average of352 percent Thus the menu costs we report in this study repre-sent a signicant share of supermarketsrsquo prots

Another way to look at the menu cost gures we report is toexpress them relative to the frequency of price changes In thelast row of Table IV we present the menu cost gures per pricechange for each chain As the table indicates the cost of changinga price in Chains AndashD ranges between $046ndash$068 for an averageof $052 For Chain E the gure is substantially larger $133 perprice change29 These gures are lower than the estimated cost of

27 This is the average of two different estimates $12945432 and$17160000 The source of the rst gure is internal record of a supermarketchain of the type and size studied here The second gure comes from Supermar-ket Business [1993 p 52]

28 We also measured the menu costs in terms of controllable operating ex-penses (which are the portion of costs that the retailer has direct control over andtherefore are often the costs that the retailer is most focused on managing) andgross margins (which measure the supermarket revenues minus direct cost of theproducts it sells) We nd that the menu costs comprise 313 percent of controlla-ble operating expenses and 281 percent of gross margins at these chains on aver-age Finally if we measure the menu costs relative to the number of productscarried per store (about 25000) then we nd that the menu costs per productaverage $423 for Chains AndashD See Table IV and its footnotes for details

29 We can also try to express the menu cost gures relative to the numberof individual items sold by these chains each year (Note the difference betweennumber of products carried and number of items sold As an example a TartarControl Crest 8oz would be considered a product carried and 300 units of themsold per year would be considered number of items sold) Using $170 as the aver-age price of all the products sold we nd that the menu cost per item sold for thefour chains is in the range of $00103ndash$00129 for an average of $00119 (see TableIV second to last row) To see the relative magnitude of these gures note thataccording to Berkowitz Kerin and Rudelius [1986 p 319] the goal of the super-market chains of the type we study ldquo is to make 1 penny of prot on each dollarof salesrdquo Thus menu cost per item sold when adjusted for the average price

THE MAGNITUDE OF MENU COSTS 813

$200ndash$300 per price change reported by Slade [1996a] Thereare several possible reasons for this (1) our menu cost gures arebased on actual measurements of the resources that go into theprice change process whereas she estimates menu costs econo-metrically as model coefcients using a mix of store-level priceand aggregate cost data (2) we cover 25000 products that thesupermarkets carry rather than a single product category (3) ourmenu cost gures do not include all components of menu costsand (4) there could be differences in wage rates that may be im-portant given the signicance of the labor cost component inmenu costs

V2 The Effect of Menu Costs on the Price Change Activity of theSupermarkets

In this section we present evidence which suggests that thesemenu costs may be forming a barrier to price change activity Tobegin with consider the effect of the item pricing law on the pricechange activity of Chain E The data on the weekly frequency ofprice changes in each chain are displayed in the last two rows ofTable I According to these gures the average weekly frequencyof price changes in Chain E is only 1578 Thus on average ChainE changes the prices of only 631 percent of its products eachweek In contrast the average weekly frequency of price changesat Chains AndashD ranges from 3223 to 4316 for the four-chain aver-age of 3916 price changes weekly So Chains AndashD change priceson 1289 to 1726 percent of their products each week yielding afour-chain average of 1566 percent Thus Chain E which facesthe item pricing law changes prices only about one-third timesas frequently as do Chains AndashD30

Moreover within Chain E there are 400 products that areexempt from the item pricing law and thereby face lower menucosts We nd that there are an average of 83 weekly pricechanges for these products yielding 21 percent of these productschanging prices So within Chain E they change prices over threetimes as frequently for products with lower menu costs than for

roughly equals one-half of their target net prot per item which seemssubstantial

30 However note that our comparison of the two types of chains may not becompletely ceteris paribus because these stores are located in different states andtherefore there may be other chain-specic factors (in addition to item pricinglaws) that distinguish these stores We do not have any specic information onthese differences We do know however that the stores in these chains are similarin size and carry similar sets of products

QUARTERLY JOURNAL OF ECONOMICS814

the products with higher menu costs Note that this nding is onthe price change activity within the same chain offering almost anatural experiment on the impact of menu costs on the chainrsquospricing behavior Hence we provide evidence both across chainsas well as across products within a chain that as the costs ofchanging price go up the frequency of price changes goes downThus the menu costs we nd are signicant enough to affect thechainrsquos price change practice

We also have additional evidence from Chains A B and Dabout these menu costs being a barrier to certain price changesand it is summarized in Table V According to the Price Manage-ment Department of Chain A the chain experiences cost in-creases on 860 products in an average week to which it wouldlike to react with a price increase31 However on average 22 per-cent of these price increases are not implemented immediatelybecause the cost of changing prices for these products is too highto make it economically worthwhile Figures of the same magni-tude were reported by other chains For example Chain D experi-ences cost increases for 961 products in an average week Out ofthese the chain adjusts prices of only 633 products The re-maining 34 percent of the prices are left unadjusted because ofthe menu costs Similarly Chain B nds it economically ineffi-cient to adjust prices of 508 ie 30 percent of its products eachweek because of menu costs This provides additional evidencethat the menu costs incurred by these chains are preventing priceadjustments to some costs changes leading to price rigidities ofthe products involved32 Note that although we do not have simi-lar data for Chain E we would expect signicantly lower num-bers on this measure at that chain These gures also suggest anupper bound on the benet of complete price exibility under thecurrent pricing practice of weekly price adjustments Howeverif new technologies (eg ESL systems) and new pricing prac-tices (eg a decentralization of the price change decisions) are

31 Our data contain information only on the frequency of cost increasesAlthough it is more than likely that the supermarkets are experiencing cost de-creases as well our data set contained no information on such decreases

32 Menu costs may even be playing a role in the observed movement towardpricing strategies that rely on fewer price changes such as EDLP [Blattberg andNeslin 1989 Lattin and Ortmeyer 1991 Marketing News April 13 1992 p 8]According to Progressive Grocer [November 1992 p 50] ldquoA growing number ofoperators say they have switched from high-low pricing [to EDLP] They cite theinefciencies of making frequent price changes rdquo Similarly Hoch Dreze andPurk [1994 p 16] state that EDLP lowers operating costs by lowering ldquo in-store labor costs because of less frequent changeovers in special displaysrdquo

adopted allowing a fundamental change in the way the pricingmechanism is currently set the managers could consider morefrequent price change activity (eg multiple times each week) asmenu costs go down

In this paper we measure the menu costs at the chainsrsquo cur-rent level of price change activity It may be worthwhile to specu-late on the shape of the cost function relating menu costs to thefrequency of price changes by assessing how these costs wouldchange if the price change activity were to increase or to decreaseIt seems likely that many of the costs we report in this paper will(approximately) change linearly with additional price changeswithin the current range of price changes the chains are under-taking (plus or minus perhaps a thousand per week) For ex-ample the labor costs associated with changing a shelf price tagcosts of verifying price changes and the costs of mistakes oc-curring during this process all increase linearly with the fre-quency of price changes This is because most of the time-consuming steps involved in the price change process must berepeated each time an additional shelf price tag is changed (seeTable II) Further we were unable to nd many tasks that gener-ated signicant returns to scale It is unclear what cost savingsare available if the price change activity drops substantially be-

QUARTERLY JOURNAL OF ECONOMICS816

low the levels it is at now Clearly if price changes were nearzero or done less frequently than weekly (say monthly) therecould be major differences in these costs

What is less clear is how these costs would change at moreextreme levels of price change activity With less frequent pricechanges the menu costs could probably be reduced signicantlyalthough the cost of deciding what prices to set initially and thecost of putting the initial shelf price tags would still remain as alower bound of the menu cost However for achieving more priceexibility by changing prices more frequently (ie multiple timeseach week) substantial changes must be undertaken At presentthe supermarket chains are set up to make the majority of theirprice changes on a weekly basis with the appropriate systems inplace to make this process most efcient For example in orderto save costs and to have higher quality price tags (eg withcolor more details greater clarity glossy etc) the chains oftensend new price tag requests to a printing shop which takes threedays to print and deliver the labels to each store Then giventhe large number of price changes taking place and the goals ofminimizing customer disruptions and labor costs (such as over-time pay) and coordinating with advertised price promotions theprices are changed in the store over a two-to-three-day period (seeTable VI) The combination of these schedule and built-in lags isacceptable under the current practice of changing prices weeklybut would have to be adjusted dramatically to allow for signifi-cantly more frequent price changes on a regular basis

Perhaps even more imposing are the costs of changing themanagerial costs associated with the current weekly system ofprice changes The process of pricing at this organizational levelis not a self-contained activity taking place in isolation from otheroperations of the supermarket management Rather it is a partof a larger system of business decisions and operations The cur-rent process of operations (such as data collection and theiranalysis management meetings coordination of the decisionsacross functional areas etc) is set up to function on a weeklybasis33 Further these management accounting and logisticssystems are currently built around a tremendous amount of in-

34 For example under the current system a chainwide category manageroperating at the corporate headquarters needs to study and assess numerouspieces of detailed information such as competitorsrsquo price and sale information fromthe last week the past weekrsquos sales at the own chain manufacturersupplier pro-motions wholesale price reductions coop allowances new product offerings shelfspace decisions coordination with newspaper advertising logistics at the ware-houses as well as at each store store differences in terms of customer characteris-tics and competitive environments productshelf selection and layout etc

35 If the supermarket chains indeed restructure the entire price change pro-cess and begin to change prices much more frequently (say two-to-three times aweek) on a regular basis then the shape of this cost function could change in anunpredictable way

V3 Relating Our Findings to the Existing Theoretical Models ofMenu Costs

In order to assess the magnitude of these menu cost guresin the context of the existing theoretical menu cost literatureconsider the following calculation experiments done within theframework of two theoretical menu cost models Blanchard andKiyotaki [1987] study a general equilibrium menu cost modelwith monopolistic competition and with unit elasticity of aggre-gate demand with respect to real money balances According totheir calculations menu costs of the magnitude of 008 percent ofrevenues which they consider ldquovery smallrdquo may be sufcient toprevent adjustment of prices Ball and Romer [1990] conductsimilar calculations in the framework of a model with imperfectcompetition and menu costs They nd that for plausible markupand labor elasticity parameter values menu costs needed to pre-vent price adjustment are 070 percent of revenues which as theysuggest are nonnegligible For smaller menu costs eg 004 per-cent of the revenue which Ball and Romer consider ldquotrivialrdquo im-plausibly large values of markup and labor elasticity parametersare needed to prevent price adjustment to monetary shocks

According to the gures in Table IV the reported menu costto revenues ratio for Chains AndashD averages 070 percent rangingfrom 061 percent to 076 percent These are signicantly largerthan the ldquotrivialrdquo 004 or 008 percent gures mentioned abovesuggesting that the menu cost gures we nd here are nontrivialFurther under the model and parameter values considered byBlanchard and Kiyotaki [1987] the menu cost gures we nd arehigher than the theoretical minimum needed to form a barrier toprice adjustments Under the model and parameter values con-sidered by Ball and Romer [1990] the reported menu costreve-nue ratio for all but one chain reaches or crosses the theoreticalthreshold of 070 needed to form a barrier to price adjustmentsThe existence of numerous unmeasured menu cost componentsdiscussed in subsection III5 also raises the possibility that theactual menu costs incurred by these chains are signicantlyhigher than that threshold This suggests that the menu costs wereport may be large enough to form a barrier to nominal priceadjustments when interpreted in the context of these models

An issue of interest in this literature is time-dependent ver-sus state-dependent pricing rules (see for example Caplin andLeahy [1991]) The evidence from our data set on the timing of

THE MAGNITUDE OF MENU COSTS 819

price changes suggests that the price change decisions in thesesupermarkets have a strong time-dependent price-setting ele-ment36 For example according to Table VI the prices in Chain Aare changed weekly according to the following schedule the pricechanges of general merchandise that is advertised is done Satur-day nights grocery and produce prices are changed Sundaynights the rest of the general merchandise prices are changed onMonday nights and the prices of advertised grocery items arechanged on Tuesday nights Thus as the gures in Table VI indi-cate over 96 percent of the price changes are done during Sundayand Monday nights However this does not imply that state-dependent pricing rules are unimportant Even if price changesacross product categories follow a prescheduled weekly time ta-ble the prices of which products to change is likely to be a state-dependent decision For example it could depend on changes insupply and demand conditions such as competitorsrsquo price changedecisions Indeed Levy Dutta and Bergen [1996] use retailstore-level orange juice price and cost data to demonstrate thatthe extent of price response to cost shocks that is the extent ofprice rigidity may depend on the nature of supply shocks37

We do not want to overstate the usefulness of our data fordirectly addressing the issue of monetary nonneutrality On onehand authors such as Caplin and Spulber [1987] have demon-strated that under certain conditions individual price rigiditymay not be sufcient for aggregate price rigidity but unfortu-nately our data do not speak directly to this issue38 On the otherhand authors such as Akerlof and Yellen [1985] Mankiw [1985]Parkin [1986] and Caplin and Leahy [1997] have shown that even

36 Danziger [1983] Caballero [1989] and Ball and Mankiw [1994] suggestthat time-dependent price adjustment of the type documented here can be optimalif the cost of gathering information about the state exceeds the cost of making theprice adjustment itself

37 We also considered the possibility of convexities in the cost of changingprices Our data do not suggest many convexities since the labor time spent inthe price tag change process the cost of printing and delivering price tags andin-store supervision time do not change with the size of a price change The onlymeasurable component of menu costs that could be convex is the cost of mistakesmade the larger the price change the higher the probability of a customer notic-ing the mistake and the larger the amount required to be refunded as compensa-tion Among the unmeasured components of menu cost the cost of corporatemanagerial time may increase with the size of a price change because larger pricechanges may require more serious consideration

38 Also see Balke and Wynne [1996] and Bryan and Cecchetti [1996] Sincewe do not have measures of how menu costs change over time our data also havelittle to say about time variation in menu costs or about the relationship betweenmenu costs and ination which during the period of the data collection (1991ndash1992) averaged about 3 percent annually

QUARTERLY JOURNAL OF ECONOMICS820

small menu costs can be relevant since they may be sufcient togenerate substantial aggregate nominal rigidity and thus largebusiness cycles Therefore as Blinder [1994] Kashyap [1995]and Slade [1996a] emphasize it is important to search for directevidence that such costs are indeed present at the micro level Bydirectly identifying documenting and measuring the magnitudeof menu costs at the store level we are taking an important stepin that direction

VI CONCLUSION AND FUTURE RESEARCH

Our main contribution is that we provide direct microeco-nomic evidence on the actual magnitude of menu costs for fourlarge U S retail supermarket chains The annual menu costs perstore at these chains average $105887 comprising 070 percentof revenues 352 percent of net prot margins and $052 perprice change on average

Further we provide evidence which suggests that thesemenu costs may be forming a barrier to price changes Specifi-cally we show that (1) supermarket chains not subject to itempricing law change prices two and a half times more frequentlythan the chain that is subject to the law (2) within the chain thatis subject to the item pricing law they change prices over threetimes as frequently for products that are exempt from this lawthan for the products which are subject to this law and (3) wend that these chains do not adjust prices of up to one-third ofthe products for which they face cost increases because of menucost considerations

When we relate these ndings to the existing theoreticalmodels of menu costs we conclude that the magnitude of menucosts we nd is large enough to be capable of having macroeco-nomic signicance Specically when considered in the context ofthe theoretical menu cost models of Blanchard and Kiyotaki[1987] and Ball and Romer [1990] we nd that the menu costgures we report are ldquonontrivialrdquo and their relative magnitudescross the minimum theoretical threshold needed to form a barrierto price adjustments

Despite the high relative magnitude of the marginal cost ofchanging price that we found the data still indicate frequentweekly price changes This is because of the high marginal bene-t of changing price which is due to the erce competition foundin the retail supermarket industry That marginal benets may

THE MAGNITUDE OF MENU COSTS 821

outweigh the marginal costs of changing prices in this industryhowever does not rule out the possibility that menu costs of themagnitude we nd here can create substantial nominal rigidityin other industries or markets In less competitive industries andmarkets menu costs of the type and magnitude we documenthere are likely to have a bigger impact on the frequency of priceadjustment and consequently on the degree of price rigidity

At a minimum the direct dollar measures of menu costs wereport here can be used as a starting point for future research onmeasuring their magnitude in other industries and establish-ments We anticipate that these menu costs will be similar inother markets which rely on posted prices (such as drugstoresdepartment stores etc) because the steps involved in the pricechange process are likely to be similar What may differ are thefrequency of price changes and the labor wage rates at thesestores For example since supermarket chains change thousandsof prices each week the total annual menu costs incurred bythese chains per store are likely to be high in comparison to otherretail formats such as chain drugstores or department storesThere are however a variety of industries for which the stepsinvolved in changing prices would be signicantly different fromthose reported in our study For example business-to-businesssales which often rely on a sales force will require changes in thelist price sheets changes in the instructions to the sales forcewhich may include education and discussion with the salespeoplein the company and so forth These business-to-business pricesalso often have more complex pricing schemes including quantitydiscounts bundling and individually negotiated prices As an-other example the composition of the cost of changing the news-stand prices of magazines [Cecchetti 1986] or the prices ofproducts sold through catalogs [Kashyap 1995] are different frommany of the menu cost components we discuss here Further thending that a centralization of pricing decisions makes the store-level managerial component of menu cost relatively small sug-gests that the managerial menu costs likely are highest insettings where price change decisions are decentralized Thus fu-ture empirical work should look at menu cost and its compositionin a variety of other industries markets and products with bothcentralized as well as decentralized price change decisions in or-der to see whether the magnitude of these costs can be general-ized and benchmarks can be established Further there aretechnological changes taking place in this and other industries

QUARTERLY JOURNAL OF ECONOMICS822

that promise to alter the structure of menu costs which deserveattention At the theoretical level our ndings suggest that it maybe worthwhile to explore models which incorporate the idea ofitem pricing laws as an additional component of menu costs

THE MAGNITUDE OF MENU COSTS 825

grocery operating expenses is labor costs [Hoch Dreze andPurk 1994]14

III2 Costs of Printing and Delivering New Price Tags

There are direct costs associated with printing and deliv-ering the price and sign tags The order must be recorded andprocessed at the chain sent to the printer recorded and pro-cessed at the printer printed packaged and then delivered toeach store The cost per tag is usually quite low $0017 per tagat Chain A which includes stock costs of $00118 per tag impres-sion and data center operator costs of $00037 per tag and mailroom handling costs of $00010 per tag There are however manyprice changes undertaken each week In total the costs of print-ing and delivering the price and sign tags range from $3048 to$10018 averaging $6014 per store per year (see Table III)These costs comprise less than 6 percent of the total menu costswe report

III3 Costs of Mistakes Made in the Process of Changing Prices

Despite the labor put into checking to make sure that theprice changes are done correctly there are still many price mis-takes that are not caught until customers discover them through-out the week and these mistakes impose costs on the chainClearly the costs associated with these errors must be consideredwhen deciding whether to change prices or not and therefore area relevant dimension of menu costs These mistakes can occur sooften that they were a feature of a Dateline segment on U Ssupermarket chains [NBC April 1992] and an article in MoneyMagazine [April 1993] Both the Money Magazine article andGoodstein [1994] report that on average 10 percent of the prod-ucts they examined had price mistakes A more recent study bythe Federal Trade Commission [1996] reports a total error rate ofabout 5 percent

The menu costs associated with these mistakes include lost

14 Our measure of labor cost may overstate the true costs of changing pricesif supermarkets hoard labor to save hiring and ring costs However this is notlikely to be the case for several reasons First the labor costs of changing priceswe report are based on actual measurements of the minimum amount of time andlabor required to accomplish the task rather than on the number of employeeshired to change prices at the store Second the adjustment in the amount of laboris usually done through hours worked which makes cost of hiring and ring lessrelevant And third the workers on the oor are routinely moved from task totask according to the need These tasks include stocking cleaning price changingcustomer service etc The workers employed by supermarket chains are alwaysbusy and so the opportunity cost of changing price is not zero Therefore laborhoarding is not likely to be an important factor in our measurements

QUARTERLY JOURNAL OF ECONOMICS806

cashier time to correct the errors scan guarantee refunds andinventory mistakes associated with incorrect price tags15 Lostcashier time is measured here in terms of wage payments Scanguarantee refunds are additional price reductions beyond the er-ror or additional items given away for free because of the mis-take Finally the inventory mistakes costs we report include onlythe cost of stockouts which occur when shelf price is lower thanintended

The mistake costs were available at Chains A C and D andthey range from $19135 to $20692 for an average of $20140 perstore annually (see Table III) These costs are the second largestcomponent of menu costs in our study comprising about 19 per-cent of the total

III4 Costs of In-Store Supervision Time Spent on ImplementingPrice Changes

Managers at the store level spend time overseeing imple-menting and troubleshooting the price change process OnlyChains A and B had a measure of the menu costs associated withthis in-store supervision time and both of these came from a self-reported number of hours spent on changing prices by the manag-ers at these chains The hours spent on changing prices were thesame across the chains approximately ve hours per week Thusthe menu costs for in-store supervision time came to $4241 and$6692 per store annually for Chains A and B respectively (seeTable III) These costs comprise less than 6 percent of the totalmenu costs we report in this paper However notice that thesemeasures do not include the cost of the management time spenton price change decisions made at corporate headquarters whichis discussed next

III5 Components of Menu Costs We Are Unable to Measure inDollar Terms

Our data set does not contain the exact dollar measures ofsome menu cost components One such component is the cost ofcorporate management time spent on price change decisions16 In

15 Other likely costs of price mistakes that we do not consider explicitlybecause we are unable to measure them in dollar terms are legal problems (whenthe scanner price is higher than the shelf price) loss in customer goodwill anddecreased protability (when the scanner price is lower than the shelf price)

16 It has been suggested that the cost of managerial decisions is one of themost important components of menu cost See for example Ball and Mankiw[1994] Kashyap [1995] and Meltzer [1995] Since the ESL system was not de-

THE MAGNITUDE OF MENU COSTS 807

the supermarket chains we study prices are generally set at cor-porate headquarters in a weekly meeting where the manager incharge of setting prices looks at a variety of information including(a) any manufacturer wholesale price changes promotions andother related issues (b) past sales for this product and (c) com-petitorsrsquo prices Based on this information and on discussionswith other managers the price-setting manager decides whetherto change prices and if so by how much

To estimate the magnitude of these managerial componentsof the menu costs consider the following In an average chainthere is at least one executive of merchandising who devotesmost of hisher time to pricing decisions In addition there areup to three senior managers who would deal with pricing andto whom category managers report There are also ten-to-twelvecategory managers who are responsible for setting prices on allthe products within their category An additional two-to-fourpeople spend full time handling the implementation of pricechanges across retail outlets coordinating the printing and deliv-ery of price tags and handling pricing problems in the systemAnother ve-to-seven workers gather the data on competitorsrsquoprices and analyse both the competitorsrsquo data and the storersquos ownscanner data to put it in a form useable by managers makingpricing decisions Thus in total there are about 21ndash27 peopleworking at the corporate headquarters on price change decisionsAssuming $150000 as the average annual salary of the executiveof merchandising and senior managers $100000 for categorymanagers and $50000 for the rest the chainwide managerialcost falls in the neighborhood of $23ndash$29 million a year whichseems a substantial amount However note that these pricing de-cision are made for the entire chain and therefore the costs perstore are signicantly less especially for the larger chains Forexample using $29 million as the upper bound the additionalannual menu cost per store for Chains AndashD which on averageoperate about 400 stores each averages about $7250 which ismuch lower than expected and is due to the centralization of theprice change decisions in the chains we study17

signed to save the costs of corporate headquarter managerial time spent on pricechange decisions the ESL company did not measure this component of menucosts The estimates reported in this section are based on the information receivedfrom the ESL company executives

17 A decentralization of the price change process say by allowing the store-level managers to make price change decisions can change these gures tremen-dously For example consider the following thought experiment conducted using

QUARTERLY JOURNAL OF ECONOMICS808

Our menu cost measures also do not include the cost ofchanging prices of direct store delivery (DSD) products Theseproducts are almost completely handled by manufacturers in-cluding stocking monitoring inventories and setting and chang-ing prices18 We have data on the weekly frequency of pricechanges of DSD products in Chain E In an average week thereare 174 price changes of DSD products which is about 10 percentof the supermarketrsquos total weekly price changes Using the costof changing the price of a regular product $133 (see Section IVfor details) the annual cost of changing prices of the DSD prod-ucts in this chain roughly equals $1203419 Our menu cost mea-sures do not include these gures since we do not have similardata for the other chains20

III6 Total Menu Costs

The total annual menu costs reported for each chain perstore are listed in the last row of Table III As the table indicatesthe menu costs range from $91416 to $114188 for an average of$105887 per store per year21 Note that these menu cost mea-

the average annual per store gures for Chains AndashD Suppose that the supermar-ket chains decentralize the price change process by hiring for each store only one-quarter of the price change managing team while at the same time they com-pletely eliminate the corporate level team The resulting annual menu cost perstore would be $830887 ( 5 $105887 1 $725000) which would dwarf any of themeasurable menu cost gures we report in this study Even if the average storeonly hired just the merchandising manager at the annual cost of $150000 itwould still incur annual managerial cost of about $255887 ( 5 $105887 1$150000) In other words such a trivial decentralization would double the store-level menu costs This would indeed make the cost of price change decisions themost important component of menu cost

18 DSD products usually are high-volume fast-moving or perishable prod-ucts such as milk soda eggs bread dairy snacks etc In the chains we studyabout 10ndash20 percent of the products are of a DSD type but that share may reachas much as 40 percent of the products carried [Direct Store Delivery Work Groupet al 1995]

19 The process of changing prices of DSD and of regular products is similarBut with DSD products there are additional costs of the time spent on driving tothe store parking and setting up the price change process at each store

20 Our measures of menu cost also do not incorporate the cost of informingconsumers about price changes which can take a variety of forms such as newspa-per ads and inserts TV and radio ads in-store promotion signs etc Finally wehave no data on lost customer goodwill and damaged reputation caused by dis-crepancies between price tag and cash register [Okun 1981 Carlton and Perloff1994 Haddock and McChesney 1994]

21 The variation in the menu costs across the chains is mostly due to wagerate and labor-efciency variations Also note that since the supermarket chainsin our sample are similar in the size of their stores carry similar sets of productsand follow similar processes of price change and price change decisions it is rea-sonable to believe that the chains incur similar types of costs Therefore as notedunderneath Table III these menu cost measures are computed by replacing theunreported gures by the averages of the available values from the other chains

THE MAGNITUDE OF MENU COSTS 809

sures include only the components we could accurately measurein dollar terms which are discussed in subsections III1ndashIII4

IV ITEM PRICING LAWS AND MENU COSTS

In this section we provide evidence on the menu costs for anadditional chain (Chain E) which unlike the other four chainsoperates in a state with an item pricing law The most importantaspect of item pricing laws is that they require a price tag on eachindividual item sold not just on the shelf which is what the otherfour chains in our sample do For example the item pricing lawin Connecticut requires that the grocers ldquoshall mark or cause tobe marked each consumer commodity which bears a UniversalProduct Code with its retail pricerdquo 22 From a menu cost perspec-tive the requirement of posting prices on every item (in additionto the shelf price tag) introduces additional costs in the processof changing prices

Although most of the steps involved in changing prices arethe same for both types of chains stores that are subject to itempricing laws have to undertake additional steps to obey this law23

The labor cost component of menu costs in Chain E totals $75127a year of which $49710 is the cost of the labor time spent onchanging the prices of individual items $3234 is the cost of thelabor time spent on shelf tag replacements and $22183 is thecost of the labor time spent on sign changes (see Table III)24 Anadditional $44168 is spent annually putting prices on new itemsas they are brought to the shelves Although we do not includethis last gure in our menu cost measures because we do not haveinformation on how much of it is due to price change activity andhow much due to just pricingmdashthese costs are clearly a directconsequence of the item pricing law The printing and deliverycost of price tags and price signs are $7644 and the mistake

22 Public Act No 75ndash391 An Act Concerning Pricing of Consumer Merchan-dise [Public Acts of the State of Connecticut 1975 Vol 1 p 390]

23 These steps which are in addition to the regular steps undertaken toreplace price tags on the shelves include (1) obtaining item price tags (2) settingup workstations (3) locating the product (4) removing an item from the shelf (5)removing old price tag (6) setting marking gun (7) applying new price tag and(8) returning the item back to the shelf

24 Since we do not have a measure of the cost of labor time spent on signchanges and the cost of in-store managerial supervision time for this chain weuse the average of the chains that report them (A and D) Note also that thehourly wage rate of $907 paid by Chain E is lower than the hourly wage of about$1400ndash$2000 paid by Chains AndashD

QUARTERLY JOURNAL OF ECONOMICS810

25 Further note that the chains with smaller menu costs are likely tochange their prices more frequently which suggests that the gures of the totalannual menu costs understate the differences between Chain E and the otherchains Indeed despite the large difference in the menu cost per price change thetotal annual menu costs per store for Chain E ($109036) are more comparable tothose of Chains AndashD ($105887)

26 In calculations that follow we use industry averages because (1) thechains did not share this proprietary information with us and (2) we were re-quired to keep the identity of these chains condential as some of these numbersare detailed enough to enable some readers to identify the chains under study

costs are $20799 These gures along with the amount of $5466for the cost of in-store managerial supervision time yield totalannual menu costs of $109036 per store

Although the magnitude of the total annual menu costs seemsimilar to the other four chains note that the average weeklyfrequency of price changes in Chain E is only 1578 which is only403 ( 5 15783916) percent of the price changes made by theother four chains Thus the average menu cost per price changefor Chain E is $133 (see Table IV last row) In contrast the corre-sponding gures for Chains AndashD average $052 Hence the menucosts per price change incurred by the supermarket chain facingitem pricing laws are more than two and a half times the amountincurred by chains that are not subject to this law25 Overallthese ndings suggest that legal restrictions of the type of itempricing laws can have a signicant impact on the menu costs in-curred by sellers

V SIGNIFICANCE OF THE MENU COSTS

The next natural question to ask is how important are thesecosts To address this question we (1) provide several relativemeasures of the menu costs (2) discuss the effect of the menucosts on supermarketsrsquo price change activity and (3) discuss mac-roeconomic implications by relating our ndings to the existingtheoretical models of menu costs In each case we provide addi-tional evidence to help assess the importance of these menu costs

V1 Relative Measures of the Menu Costs

In order to assess the relative magnitude of the menu costsreported in Section IV we now present the menu cost gures rela-tive to the average store-level revenues and net prot margins26

In addition we present the menu cost gures per price changeThe annual average revenues of a large U S supermarket

chain of the type and size included in our sample is $15052716

Net prot margin which measures the revenues minus allcosts is approximately 1ndash3 percent of revenues for these chains[Montgomery 1994] so we use 2 percent as a working averageThe reason for the low prot rate in this industry is the intensecompetition [Calatone et al 1989] especially at the regional level[Chevalier 1995] which has been increasing since the early 1990s[Progressive Grocer November 1992 p 50] It follows that theaverage store protability for these chains equals $301054 peryear Therefore the ratio of total menu cost to net margin forChains AndashD ranges between 304ndash379 percent for an average of352 percent Thus the menu costs we report in this study repre-sent a signicant share of supermarketsrsquo prots

Another way to look at the menu cost gures we report is toexpress them relative to the frequency of price changes In thelast row of Table IV we present the menu cost gures per pricechange for each chain As the table indicates the cost of changinga price in Chains AndashD ranges between $046ndash$068 for an averageof $052 For Chain E the gure is substantially larger $133 perprice change29 These gures are lower than the estimated cost of

27 This is the average of two different estimates $12945432 and$17160000 The source of the rst gure is internal record of a supermarketchain of the type and size studied here The second gure comes from Supermar-ket Business [1993 p 52]

28 We also measured the menu costs in terms of controllable operating ex-penses (which are the portion of costs that the retailer has direct control over andtherefore are often the costs that the retailer is most focused on managing) andgross margins (which measure the supermarket revenues minus direct cost of theproducts it sells) We nd that the menu costs comprise 313 percent of controlla-ble operating expenses and 281 percent of gross margins at these chains on aver-age Finally if we measure the menu costs relative to the number of productscarried per store (about 25000) then we nd that the menu costs per productaverage $423 for Chains AndashD See Table IV and its footnotes for details

29 We can also try to express the menu cost gures relative to the numberof individual items sold by these chains each year (Note the difference betweennumber of products carried and number of items sold As an example a TartarControl Crest 8oz would be considered a product carried and 300 units of themsold per year would be considered number of items sold) Using $170 as the aver-age price of all the products sold we nd that the menu cost per item sold for thefour chains is in the range of $00103ndash$00129 for an average of $00119 (see TableIV second to last row) To see the relative magnitude of these gures note thataccording to Berkowitz Kerin and Rudelius [1986 p 319] the goal of the super-market chains of the type we study ldquo is to make 1 penny of prot on each dollarof salesrdquo Thus menu cost per item sold when adjusted for the average price

$200ndash$300 per price change reported by Slade [1996a] Thereare several possible reasons for this (1) our menu cost gures arebased on actual measurements of the resources that go into theprice change process whereas she estimates menu costs econo-metrically as model coefcients using a mix of store-level priceand aggregate cost data (2) we cover 25000 products that thesupermarkets carry rather than a single product category (3) ourmenu cost gures do not include all components of menu costsand (4) there could be differences in wage rates that may be im-portant given the signicance of the labor cost component inmenu costs

V2 The Effect of Menu Costs on the Price Change Activity of theSupermarkets

In this section we present evidence which suggests that thesemenu costs may be forming a barrier to price change activity Tobegin with consider the effect of the item pricing law on the pricechange activity of Chain E The data on the weekly frequency ofprice changes in each chain are displayed in the last two rows ofTable I According to these gures the average weekly frequencyof price changes in Chain E is only 1578 Thus on average ChainE changes the prices of only 631 percent of its products eachweek In contrast the average weekly frequency of price changesat Chains AndashD ranges from 3223 to 4316 for the four-chain aver-age of 3916 price changes weekly So Chains AndashD change priceson 1289 to 1726 percent of their products each week yielding afour-chain average of 1566 percent Thus Chain E which facesthe item pricing law changes prices only about one-third timesas frequently as do Chains AndashD30

Moreover within Chain E there are 400 products that areexempt from the item pricing law and thereby face lower menucosts We nd that there are an average of 83 weekly pricechanges for these products yielding 21 percent of these productschanging prices So within Chain E they change prices over threetimes as frequently for products with lower menu costs than for

roughly equals one-half of their target net prot per item which seemssubstantial

30 However note that our comparison of the two types of chains may not becompletely ceteris paribus because these stores are located in different states andtherefore there may be other chain-specic factors (in addition to item pricinglaws) that distinguish these stores We do not have any specic information onthese differences We do know however that the stores in these chains are similarin size and carry similar sets of products

QUARTERLY JOURNAL OF ECONOMICS814

the products with higher menu costs Note that this nding is onthe price change activity within the same chain offering almost anatural experiment on the impact of menu costs on the chainrsquospricing behavior Hence we provide evidence both across chainsas well as across products within a chain that as the costs ofchanging price go up the frequency of price changes goes downThus the menu costs we nd are signicant enough to affect thechainrsquos price change practice

We also have additional evidence from Chains A B and Dabout these menu costs being a barrier to certain price changesand it is summarized in Table V According to the Price Manage-ment Department of Chain A the chain experiences cost in-creases on 860 products in an average week to which it wouldlike to react with a price increase31 However on average 22 per-cent of these price increases are not implemented immediatelybecause the cost of changing prices for these products is too highto make it economically worthwhile Figures of the same magni-tude were reported by other chains For example Chain D experi-ences cost increases for 961 products in an average week Out ofthese the chain adjusts prices of only 633 products The re-maining 34 percent of the prices are left unadjusted because ofthe menu costs Similarly Chain B nds it economically ineffi-cient to adjust prices of 508 ie 30 percent of its products eachweek because of menu costs This provides additional evidencethat the menu costs incurred by these chains are preventing priceadjustments to some costs changes leading to price rigidities ofthe products involved32 Note that although we do not have simi-lar data for Chain E we would expect signicantly lower num-bers on this measure at that chain These gures also suggest anupper bound on the benet of complete price exibility under thecurrent pricing practice of weekly price adjustments Howeverif new technologies (eg ESL systems) and new pricing prac-tices (eg a decentralization of the price change decisions) are

31 Our data contain information only on the frequency of cost increasesAlthough it is more than likely that the supermarkets are experiencing cost de-creases as well our data set contained no information on such decreases

32 Menu costs may even be playing a role in the observed movement towardpricing strategies that rely on fewer price changes such as EDLP [Blattberg andNeslin 1989 Lattin and Ortmeyer 1991 Marketing News April 13 1992 p 8]According to Progressive Grocer [November 1992 p 50] ldquoA growing number ofoperators say they have switched from high-low pricing [to EDLP] They cite theinefciencies of making frequent price changes rdquo Similarly Hoch Dreze andPurk [1994 p 16] state that EDLP lowers operating costs by lowering ldquo in-store labor costs because of less frequent changeovers in special displaysrdquo

adopted allowing a fundamental change in the way the pricingmechanism is currently set the managers could consider morefrequent price change activity (eg multiple times each week) asmenu costs go down

In this paper we measure the menu costs at the chainsrsquo cur-rent level of price change activity It may be worthwhile to specu-late on the shape of the cost function relating menu costs to thefrequency of price changes by assessing how these costs wouldchange if the price change activity were to increase or to decreaseIt seems likely that many of the costs we report in this paper will(approximately) change linearly with additional price changeswithin the current range of price changes the chains are under-taking (plus or minus perhaps a thousand per week) For ex-ample the labor costs associated with changing a shelf price tagcosts of verifying price changes and the costs of mistakes oc-curring during this process all increase linearly with the fre-quency of price changes This is because most of the time-consuming steps involved in the price change process must berepeated each time an additional shelf price tag is changed (seeTable II) Further we were unable to nd many tasks that gener-ated signicant returns to scale It is unclear what cost savingsare available if the price change activity drops substantially be-

QUARTERLY JOURNAL OF ECONOMICS816

low the levels it is at now Clearly if price changes were nearzero or done less frequently than weekly (say monthly) therecould be major differences in these costs

What is less clear is how these costs would change at moreextreme levels of price change activity With less frequent pricechanges the menu costs could probably be reduced signicantlyalthough the cost of deciding what prices to set initially and thecost of putting the initial shelf price tags would still remain as alower bound of the menu cost However for achieving more priceexibility by changing prices more frequently (ie multiple timeseach week) substantial changes must be undertaken At presentthe supermarket chains are set up to make the majority of theirprice changes on a weekly basis with the appropriate systems inplace to make this process most efcient For example in orderto save costs and to have higher quality price tags (eg withcolor more details greater clarity glossy etc) the chains oftensend new price tag requests to a printing shop which takes threedays to print and deliver the labels to each store Then giventhe large number of price changes taking place and the goals ofminimizing customer disruptions and labor costs (such as over-time pay) and coordinating with advertised price promotions theprices are changed in the store over a two-to-three-day period (seeTable VI) The combination of these schedule and built-in lags isacceptable under the current practice of changing prices weeklybut would have to be adjusted dramatically to allow for signifi-cantly more frequent price changes on a regular basis

Perhaps even more imposing are the costs of changing themanagerial costs associated with the current weekly system ofprice changes The process of pricing at this organizational levelis not a self-contained activity taking place in isolation from otheroperations of the supermarket management Rather it is a partof a larger system of business decisions and operations The cur-rent process of operations (such as data collection and theiranalysis management meetings coordination of the decisionsacross functional areas etc) is set up to function on a weeklybasis33 Further these management accounting and logisticssystems are currently built around a tremendous amount of in-

35 If the supermarket chains indeed restructure the entire price change pro-cess and begin to change prices much more frequently (say two-to-three times aweek) on a regular basis then the shape of this cost function could change in anunpredictable way

V3 Relating Our Findings to the Existing Theoretical Models ofMenu Costs

In order to assess the magnitude of these menu cost guresin the context of the existing theoretical menu cost literatureconsider the following calculation experiments done within theframework of two theoretical menu cost models Blanchard andKiyotaki [1987] study a general equilibrium menu cost modelwith monopolistic competition and with unit elasticity of aggre-gate demand with respect to real money balances According totheir calculations menu costs of the magnitude of 008 percent ofrevenues which they consider ldquovery smallrdquo may be sufcient toprevent adjustment of prices Ball and Romer [1990] conductsimilar calculations in the framework of a model with imperfectcompetition and menu costs They nd that for plausible markupand labor elasticity parameter values menu costs needed to pre-vent price adjustment are 070 percent of revenues which as theysuggest are nonnegligible For smaller menu costs eg 004 per-cent of the revenue which Ball and Romer consider ldquotrivialrdquo im-plausibly large values of markup and labor elasticity parametersare needed to prevent price adjustment to monetary shocks

According to the gures in Table IV the reported menu costto revenues ratio for Chains AndashD averages 070 percent rangingfrom 061 percent to 076 percent These are signicantly largerthan the ldquotrivialrdquo 004 or 008 percent gures mentioned abovesuggesting that the menu cost gures we nd here are nontrivialFurther under the model and parameter values considered byBlanchard and Kiyotaki [1987] the menu cost gures we nd arehigher than the theoretical minimum needed to form a barrier toprice adjustments Under the model and parameter values con-sidered by Ball and Romer [1990] the reported menu costreve-nue ratio for all but one chain reaches or crosses the theoreticalthreshold of 070 needed to form a barrier to price adjustmentsThe existence of numerous unmeasured menu cost componentsdiscussed in subsection III5 also raises the possibility that theactual menu costs incurred by these chains are signicantlyhigher than that threshold This suggests that the menu costs wereport may be large enough to form a barrier to nominal priceadjustments when interpreted in the context of these models

An issue of interest in this literature is time-dependent ver-sus state-dependent pricing rules (see for example Caplin andLeahy [1991]) The evidence from our data set on the timing of

THE MAGNITUDE OF MENU COSTS 819

price changes suggests that the price change decisions in thesesupermarkets have a strong time-dependent price-setting ele-ment36 For example according to Table VI the prices in Chain Aare changed weekly according to the following schedule the pricechanges of general merchandise that is advertised is done Satur-day nights grocery and produce prices are changed Sundaynights the rest of the general merchandise prices are changed onMonday nights and the prices of advertised grocery items arechanged on Tuesday nights Thus as the gures in Table VI indi-cate over 96 percent of the price changes are done during Sundayand Monday nights However this does not imply that state-dependent pricing rules are unimportant Even if price changesacross product categories follow a prescheduled weekly time ta-ble the prices of which products to change is likely to be a state-dependent decision For example it could depend on changes insupply and demand conditions such as competitorsrsquo price changedecisions Indeed Levy Dutta and Bergen [1996] use retailstore-level orange juice price and cost data to demonstrate thatthe extent of price response to cost shocks that is the extent ofprice rigidity may depend on the nature of supply shocks37

We do not want to overstate the usefulness of our data fordirectly addressing the issue of monetary nonneutrality On onehand authors such as Caplin and Spulber [1987] have demon-strated that under certain conditions individual price rigiditymay not be sufcient for aggregate price rigidity but unfortu-nately our data do not speak directly to this issue38 On the otherhand authors such as Akerlof and Yellen [1985] Mankiw [1985]Parkin [1986] and Caplin and Leahy [1997] have shown that even

36 Danziger [1983] Caballero [1989] and Ball and Mankiw [1994] suggestthat time-dependent price adjustment of the type documented here can be optimalif the cost of gathering information about the state exceeds the cost of making theprice adjustment itself

37 We also considered the possibility of convexities in the cost of changingprices Our data do not suggest many convexities since the labor time spent inthe price tag change process the cost of printing and delivering price tags andin-store supervision time do not change with the size of a price change The onlymeasurable component of menu costs that could be convex is the cost of mistakesmade the larger the price change the higher the probability of a customer notic-ing the mistake and the larger the amount required to be refunded as compensa-tion Among the unmeasured components of menu cost the cost of corporatemanagerial time may increase with the size of a price change because larger pricechanges may require more serious consideration

38 Also see Balke and Wynne [1996] and Bryan and Cecchetti [1996] Sincewe do not have measures of how menu costs change over time our data also havelittle to say about time variation in menu costs or about the relationship betweenmenu costs and ination which during the period of the data collection (1991ndash1992) averaged about 3 percent annually

QUARTERLY JOURNAL OF ECONOMICS820

small menu costs can be relevant since they may be sufcient togenerate substantial aggregate nominal rigidity and thus largebusiness cycles Therefore as Blinder [1994] Kashyap [1995]and Slade [1996a] emphasize it is important to search for directevidence that such costs are indeed present at the micro level Bydirectly identifying documenting and measuring the magnitudeof menu costs at the store level we are taking an important stepin that direction

VI CONCLUSION AND FUTURE RESEARCH

Our main contribution is that we provide direct microeco-nomic evidence on the actual magnitude of menu costs for fourlarge U S retail supermarket chains The annual menu costs perstore at these chains average $105887 comprising 070 percentof revenues 352 percent of net prot margins and $052 perprice change on average

Further we provide evidence which suggests that thesemenu costs may be forming a barrier to price changes Specifi-cally we show that (1) supermarket chains not subject to itempricing law change prices two and a half times more frequentlythan the chain that is subject to the law (2) within the chain thatis subject to the item pricing law they change prices over threetimes as frequently for products that are exempt from this lawthan for the products which are subject to this law and (3) wend that these chains do not adjust prices of up to one-third ofthe products for which they face cost increases because of menucost considerations

When we relate these ndings to the existing theoreticalmodels of menu costs we conclude that the magnitude of menucosts we nd is large enough to be capable of having macroeco-nomic signicance Specically when considered in the context ofthe theoretical menu cost models of Blanchard and Kiyotaki[1987] and Ball and Romer [1990] we nd that the menu costgures we report are ldquonontrivialrdquo and their relative magnitudescross the minimum theoretical threshold needed to form a barrierto price adjustments

Despite the high relative magnitude of the marginal cost ofchanging price that we found the data still indicate frequentweekly price changes This is because of the high marginal bene-t of changing price which is due to the erce competition foundin the retail supermarket industry That marginal benets may

THE MAGNITUDE OF MENU COSTS 821

outweigh the marginal costs of changing prices in this industryhowever does not rule out the possibility that menu costs of themagnitude we nd here can create substantial nominal rigidityin other industries or markets In less competitive industries andmarkets menu costs of the type and magnitude we documenthere are likely to have a bigger impact on the frequency of priceadjustment and consequently on the degree of price rigidity

At a minimum the direct dollar measures of menu costs wereport here can be used as a starting point for future research onmeasuring their magnitude in other industries and establish-ments We anticipate that these menu costs will be similar inother markets which rely on posted prices (such as drugstoresdepartment stores etc) because the steps involved in the pricechange process are likely to be similar What may differ are thefrequency of price changes and the labor wage rates at thesestores For example since supermarket chains change thousandsof prices each week the total annual menu costs incurred bythese chains per store are likely to be high in comparison to otherretail formats such as chain drugstores or department storesThere are however a variety of industries for which the stepsinvolved in changing prices would be signicantly different fromthose reported in our study For example business-to-businesssales which often rely on a sales force will require changes in thelist price sheets changes in the instructions to the sales forcewhich may include education and discussion with the salespeoplein the company and so forth These business-to-business pricesalso often have more complex pricing schemes including quantitydiscounts bundling and individually negotiated prices As an-other example the composition of the cost of changing the news-stand prices of magazines [Cecchetti 1986] or the prices ofproducts sold through catalogs [Kashyap 1995] are different frommany of the menu cost components we discuss here Further thending that a centralization of pricing decisions makes the store-level managerial component of menu cost relatively small sug-gests that the managerial menu costs likely are highest insettings where price change decisions are decentralized Thus fu-ture empirical work should look at menu cost and its compositionin a variety of other industries markets and products with bothcentralized as well as decentralized price change decisions in or-der to see whether the magnitude of these costs can be general-ized and benchmarks can be established Further there aretechnological changes taking place in this and other industries

that promise to alter the structure of menu costs which deserveattention At the theoretical level our ndings suggest that it maybe worthwhile to explore models which incorporate the idea ofitem pricing laws as an additional component of menu costs

Managers at the store level spend time overseeing imple-menting and troubleshooting the price change process OnlyChains A and B had a measure of the menu costs associated withthis in-store supervision time and both of these came from a self-reported number of hours spent on changing prices by the manag-ers at these chains The hours spent on changing prices were thesame across the chains approximately ve hours per week Thusthe menu costs for in-store supervision time came to $4241 and$6692 per store annually for Chains A and B respectively (seeTable III) These costs comprise less than 6 percent of the totalmenu costs we report in this paper However notice that thesemeasures do not include the cost of the management time spenton price change decisions made at corporate headquarters whichis discussed next

III5 Components of Menu Costs We Are Unable to Measure inDollar Terms

Our data set does not contain the exact dollar measures ofsome menu cost components One such component is the cost ofcorporate management time spent on price change decisions16 In

15 Other likely costs of price mistakes that we do not consider explicitlybecause we are unable to measure them in dollar terms are legal problems (whenthe scanner price is higher than the shelf price) loss in customer goodwill anddecreased protability (when the scanner price is lower than the shelf price)

16 It has been suggested that the cost of managerial decisions is one of themost important components of menu cost See for example Ball and Mankiw[1994] Kashyap [1995] and Meltzer [1995] Since the ESL system was not de-

THE MAGNITUDE OF MENU COSTS 807

the supermarket chains we study prices are generally set at cor-porate headquarters in a weekly meeting where the manager incharge of setting prices looks at a variety of information including(a) any manufacturer wholesale price changes promotions andother related issues (b) past sales for this product and (c) com-petitorsrsquo prices Based on this information and on discussionswith other managers the price-setting manager decides whetherto change prices and if so by how much

To estimate the magnitude of these managerial componentsof the menu costs consider the following In an average chainthere is at least one executive of merchandising who devotesmost of hisher time to pricing decisions In addition there areup to three senior managers who would deal with pricing andto whom category managers report There are also ten-to-twelvecategory managers who are responsible for setting prices on allthe products within their category An additional two-to-fourpeople spend full time handling the implementation of pricechanges across retail outlets coordinating the printing and deliv-ery of price tags and handling pricing problems in the systemAnother ve-to-seven workers gather the data on competitorsrsquoprices and analyse both the competitorsrsquo data and the storersquos ownscanner data to put it in a form useable by managers makingpricing decisions Thus in total there are about 21ndash27 peopleworking at the corporate headquarters on price change decisionsAssuming $150000 as the average annual salary of the executiveof merchandising and senior managers $100000 for categorymanagers and $50000 for the rest the chainwide managerialcost falls in the neighborhood of $23ndash$29 million a year whichseems a substantial amount However note that these pricing de-cision are made for the entire chain and therefore the costs perstore are signicantly less especially for the larger chains Forexample using $29 million as the upper bound the additionalannual menu cost per store for Chains AndashD which on averageoperate about 400 stores each averages about $7250 which ismuch lower than expected and is due to the centralization of theprice change decisions in the chains we study17

signed to save the costs of corporate headquarter managerial time spent on pricechange decisions the ESL company did not measure this component of menucosts The estimates reported in this section are based on the information receivedfrom the ESL company executives

17 A decentralization of the price change process say by allowing the store-level managers to make price change decisions can change these gures tremen-dously For example consider the following thought experiment conducted using

QUARTERLY JOURNAL OF ECONOMICS808

Our menu cost measures also do not include the cost ofchanging prices of direct store delivery (DSD) products Theseproducts are almost completely handled by manufacturers in-cluding stocking monitoring inventories and setting and chang-ing prices18 We have data on the weekly frequency of pricechanges of DSD products in Chain E In an average week thereare 174 price changes of DSD products which is about 10 percentof the supermarketrsquos total weekly price changes Using the costof changing the price of a regular product $133 (see Section IVfor details) the annual cost of changing prices of the DSD prod-ucts in this chain roughly equals $1203419 Our menu cost mea-sures do not include these gures since we do not have similardata for the other chains20

III6 Total Menu Costs

The total annual menu costs reported for each chain perstore are listed in the last row of Table III As the table indicatesthe menu costs range from $91416 to $114188 for an average of$105887 per store per year21 Note that these menu cost mea-

the average annual per store gures for Chains AndashD Suppose that the supermar-ket chains decentralize the price change process by hiring for each store only one-quarter of the price change managing team while at the same time they com-pletely eliminate the corporate level team The resulting annual menu cost perstore would be $830887 ( 5 $105887 1 $725000) which would dwarf any of themeasurable menu cost gures we report in this study Even if the average storeonly hired just the merchandising manager at the annual cost of $150000 itwould still incur annual managerial cost of about $255887 ( 5 $105887 1$150000) In other words such a trivial decentralization would double the store-level menu costs This would indeed make the cost of price change decisions themost important component of menu cost

18 DSD products usually are high-volume fast-moving or perishable prod-ucts such as milk soda eggs bread dairy snacks etc In the chains we studyabout 10ndash20 percent of the products are of a DSD type but that share may reachas much as 40 percent of the products carried [Direct Store Delivery Work Groupet al 1995]

19 The process of changing prices of DSD and of regular products is similarBut with DSD products there are additional costs of the time spent on driving tothe store parking and setting up the price change process at each store

20 Our measures of menu cost also do not incorporate the cost of informingconsumers about price changes which can take a variety of forms such as newspa-per ads and inserts TV and radio ads in-store promotion signs etc Finally wehave no data on lost customer goodwill and damaged reputation caused by dis-crepancies between price tag and cash register [Okun 1981 Carlton and Perloff1994 Haddock and McChesney 1994]

21 The variation in the menu costs across the chains is mostly due to wagerate and labor-efciency variations Also note that since the supermarket chainsin our sample are similar in the size of their stores carry similar sets of productsand follow similar processes of price change and price change decisions it is rea-sonable to believe that the chains incur similar types of costs Therefore as notedunderneath Table III these menu cost measures are computed by replacing theunreported gures by the averages of the available values from the other chains

sures include only the components we could accurately measurein dollar terms which are discussed in subsections III1ndashIII4

IV ITEM PRICING LAWS AND MENU COSTS

In this section we provide evidence on the menu costs for anadditional chain (Chain E) which unlike the other four chainsoperates in a state with an item pricing law The most importantaspect of item pricing laws is that they require a price tag on eachindividual item sold not just on the shelf which is what the otherfour chains in our sample do For example the item pricing lawin Connecticut requires that the grocers ldquoshall mark or cause tobe marked each consumer commodity which bears a UniversalProduct Code with its retail pricerdquo 22 From a menu cost perspec-tive the requirement of posting prices on every item (in additionto the shelf price tag) introduces additional costs in the processof changing prices

Although most of the steps involved in changing prices arethe same for both types of chains stores that are subject to itempricing laws have to undertake additional steps to obey this law23

The labor cost component of menu costs in Chain E totals $75127a year of which $49710 is the cost of the labor time spent onchanging the prices of individual items $3234 is the cost of thelabor time spent on shelf tag replacements and $22183 is thecost of the labor time spent on sign changes (see Table III)24 Anadditional $44168 is spent annually putting prices on new itemsas they are brought to the shelves Although we do not includethis last gure in our menu cost measures because we do not haveinformation on how much of it is due to price change activity andhow much due to just pricingmdashthese costs are clearly a directconsequence of the item pricing law The printing and deliverycost of price tags and price signs are $7644 and the mistake

22 Public Act No 75ndash391 An Act Concerning Pricing of Consumer Merchan-dise [Public Acts of the State of Connecticut 1975 Vol 1 p 390]

23 These steps which are in addition to the regular steps undertaken toreplace price tags on the shelves include (1) obtaining item price tags (2) settingup workstations (3) locating the product (4) removing an item from the shelf (5)removing old price tag (6) setting marking gun (7) applying new price tag and(8) returning the item back to the shelf

24 Since we do not have a measure of the cost of labor time spent on signchanges and the cost of in-store managerial supervision time for this chain weuse the average of the chains that report them (A and D) Note also that thehourly wage rate of $907 paid by Chain E is lower than the hourly wage of about$1400ndash$2000 paid by Chains AndashD

QUARTERLY JOURNAL OF ECONOMICS810

25 Further note that the chains with smaller menu costs are likely tochange their prices more frequently which suggests that the gures of the totalannual menu costs understate the differences between Chain E and the otherchains Indeed despite the large difference in the menu cost per price change thetotal annual menu costs per store for Chain E ($109036) are more comparable tothose of Chains AndashD ($105887)

26 In calculations that follow we use industry averages because (1) thechains did not share this proprietary information with us and (2) we were re-quired to keep the identity of these chains condential as some of these numbersare detailed enough to enable some readers to identify the chains under study

costs are $20799 These gures along with the amount of $5466for the cost of in-store managerial supervision time yield totalannual menu costs of $109036 per store

Although the magnitude of the total annual menu costs seemsimilar to the other four chains note that the average weeklyfrequency of price changes in Chain E is only 1578 which is only403 ( 5 15783916) percent of the price changes made by theother four chains Thus the average menu cost per price changefor Chain E is $133 (see Table IV last row) In contrast the corre-sponding gures for Chains AndashD average $052 Hence the menucosts per price change incurred by the supermarket chain facingitem pricing laws are more than two and a half times the amountincurred by chains that are not subject to this law25 Overallthese ndings suggest that legal restrictions of the type of itempricing laws can have a signicant impact on the menu costs in-curred by sellers

V SIGNIFICANCE OF THE MENU COSTS

The next natural question to ask is how important are thesecosts To address this question we (1) provide several relativemeasures of the menu costs (2) discuss the effect of the menucosts on supermarketsrsquo price change activity and (3) discuss mac-roeconomic implications by relating our ndings to the existingtheoretical models of menu costs In each case we provide addi-tional evidence to help assess the importance of these menu costs

V1 Relative Measures of the Menu Costs

In order to assess the relative magnitude of the menu costsreported in Section IV we now present the menu cost gures rela-tive to the average store-level revenues and net prot margins26

In addition we present the menu cost gures per price changeThe annual average revenues of a large U S supermarket

chain of the type and size included in our sample is $15052716

per store27 According to the second row of Table IV the ratio ofmenu costs to revenues for Chains AndashD ranges between 061ndash076percent averaging 070 percent28 We relate the size of thesegures to the existing theoretical menu cost models in sub-section V3

Net prot margin which measures the revenues minus allcosts is approximately 1ndash3 percent of revenues for these chains[Montgomery 1994] so we use 2 percent as a working averageThe reason for the low prot rate in this industry is the intensecompetition [Calatone et al 1989] especially at the regional level[Chevalier 1995] which has been increasing since the early 1990s[Progressive Grocer November 1992 p 50] It follows that theaverage store protability for these chains equals $301054 peryear Therefore the ratio of total menu cost to net margin forChains AndashD ranges between 304ndash379 percent for an average of352 percent Thus the menu costs we report in this study repre-sent a signicant share of supermarketsrsquo prots

Another way to look at the menu cost gures we report is toexpress them relative to the frequency of price changes In thelast row of Table IV we present the menu cost gures per pricechange for each chain As the table indicates the cost of changinga price in Chains AndashD ranges between $046ndash$068 for an averageof $052 For Chain E the gure is substantially larger $133 perprice change29 These gures are lower than the estimated cost of

27 This is the average of two different estimates $12945432 and$17160000 The source of the rst gure is internal record of a supermarketchain of the type and size studied here The second gure comes from Supermar-ket Business [1993 p 52]

28 We also measured the menu costs in terms of controllable operating ex-penses (which are the portion of costs that the retailer has direct control over andtherefore are often the costs that the retailer is most focused on managing) andgross margins (which measure the supermarket revenues minus direct cost of theproducts it sells) We nd that the menu costs comprise 313 percent of controlla-ble operating expenses and 281 percent of gross margins at these chains on aver-age Finally if we measure the menu costs relative to the number of productscarried per store (about 25000) then we nd that the menu costs per productaverage $423 for Chains AndashD See Table IV and its footnotes for details

29 We can also try to express the menu cost gures relative to the numberof individual items sold by these chains each year (Note the difference betweennumber of products carried and number of items sold As an example a TartarControl Crest 8oz would be considered a product carried and 300 units of themsold per year would be considered number of items sold) Using $170 as the aver-age price of all the products sold we nd that the menu cost per item sold for thefour chains is in the range of $00103ndash$00129 for an average of $00119 (see TableIV second to last row) To see the relative magnitude of these gures note thataccording to Berkowitz Kerin and Rudelius [1986 p 319] the goal of the super-market chains of the type we study ldquo is to make 1 penny of prot on each dollarof salesrdquo Thus menu cost per item sold when adjusted for the average price

THE MAGNITUDE OF MENU COSTS 813

$200ndash$300 per price change reported by Slade [1996a] Thereare several possible reasons for this (1) our menu cost gures arebased on actual measurements of the resources that go into theprice change process whereas she estimates menu costs econo-metrically as model coefcients using a mix of store-level priceand aggregate cost data (2) we cover 25000 products that thesupermarkets carry rather than a single product category (3) ourmenu cost gures do not include all components of menu costsand (4) there could be differences in wage rates that may be im-portant given the signicance of the labor cost component inmenu costs

V2 The Effect of Menu Costs on the Price Change Activity of theSupermarkets

In this section we present evidence which suggests that thesemenu costs may be forming a barrier to price change activity Tobegin with consider the effect of the item pricing law on the pricechange activity of Chain E The data on the weekly frequency ofprice changes in each chain are displayed in the last two rows ofTable I According to these gures the average weekly frequencyof price changes in Chain E is only 1578 Thus on average ChainE changes the prices of only 631 percent of its products eachweek In contrast the average weekly frequency of price changesat Chains AndashD ranges from 3223 to 4316 for the four-chain aver-age of 3916 price changes weekly So Chains AndashD change priceson 1289 to 1726 percent of their products each week yielding afour-chain average of 1566 percent Thus Chain E which facesthe item pricing law changes prices only about one-third timesas frequently as do Chains AndashD30

Moreover within Chain E there are 400 products that areexempt from the item pricing law and thereby face lower menucosts We nd that there are an average of 83 weekly pricechanges for these products yielding 21 percent of these productschanging prices So within Chain E they change prices over threetimes as frequently for products with lower menu costs than for

roughly equals one-half of their target net prot per item which seemssubstantial

30 However note that our comparison of the two types of chains may not becompletely ceteris paribus because these stores are located in different states andtherefore there may be other chain-specic factors (in addition to item pricinglaws) that distinguish these stores We do not have any specic information onthese differences We do know however that the stores in these chains are similarin size and carry similar sets of products

QUARTERLY JOURNAL OF ECONOMICS814

the products with higher menu costs Note that this nding is onthe price change activity within the same chain offering almost anatural experiment on the impact of menu costs on the chainrsquospricing behavior Hence we provide evidence both across chainsas well as across products within a chain that as the costs ofchanging price go up the frequency of price changes goes downThus the menu costs we nd are signicant enough to affect thechainrsquos price change practice

We also have additional evidence from Chains A B and Dabout these menu costs being a barrier to certain price changesand it is summarized in Table V According to the Price Manage-ment Department of Chain A the chain experiences cost in-creases on 860 products in an average week to which it wouldlike to react with a price increase31 However on average 22 per-cent of these price increases are not implemented immediatelybecause the cost of changing prices for these products is too highto make it economically worthwhile Figures of the same magni-tude were reported by other chains For example Chain D experi-ences cost increases for 961 products in an average week Out ofthese the chain adjusts prices of only 633 products The re-maining 34 percent of the prices are left unadjusted because ofthe menu costs Similarly Chain B nds it economically ineffi-cient to adjust prices of 508 ie 30 percent of its products eachweek because of menu costs This provides additional evidencethat the menu costs incurred by these chains are preventing priceadjustments to some costs changes leading to price rigidities ofthe products involved32 Note that although we do not have simi-lar data for Chain E we would expect signicantly lower num-bers on this measure at that chain These gures also suggest anupper bound on the benet of complete price exibility under thecurrent pricing practice of weekly price adjustments Howeverif new technologies (eg ESL systems) and new pricing prac-tices (eg a decentralization of the price change decisions) are

31 Our data contain information only on the frequency of cost increasesAlthough it is more than likely that the supermarkets are experiencing cost de-creases as well our data set contained no information on such decreases

32 Menu costs may even be playing a role in the observed movement towardpricing strategies that rely on fewer price changes such as EDLP [Blattberg andNeslin 1989 Lattin and Ortmeyer 1991 Marketing News April 13 1992 p 8]According to Progressive Grocer [November 1992 p 50] ldquoA growing number ofoperators say they have switched from high-low pricing [to EDLP] They cite theinefciencies of making frequent price changes rdquo Similarly Hoch Dreze andPurk [1994 p 16] state that EDLP lowers operating costs by lowering ldquo in-store labor costs because of less frequent changeovers in special displaysrdquo

adopted allowing a fundamental change in the way the pricingmechanism is currently set the managers could consider morefrequent price change activity (eg multiple times each week) asmenu costs go down

In this paper we measure the menu costs at the chainsrsquo cur-rent level of price change activity It may be worthwhile to specu-late on the shape of the cost function relating menu costs to thefrequency of price changes by assessing how these costs wouldchange if the price change activity were to increase or to decreaseIt seems likely that many of the costs we report in this paper will(approximately) change linearly with additional price changeswithin the current range of price changes the chains are under-taking (plus or minus perhaps a thousand per week) For ex-ample the labor costs associated with changing a shelf price tagcosts of verifying price changes and the costs of mistakes oc-curring during this process all increase linearly with the fre-quency of price changes This is because most of the time-consuming steps involved in the price change process must berepeated each time an additional shelf price tag is changed (seeTable II) Further we were unable to nd many tasks that gener-ated signicant returns to scale It is unclear what cost savingsare available if the price change activity drops substantially be-

low the levels it is at now Clearly if price changes were nearzero or done less frequently than weekly (say monthly) therecould be major differences in these costs

What is less clear is how these costs would change at moreextreme levels of price change activity With less frequent pricechanges the menu costs could probably be reduced signicantlyalthough the cost of deciding what prices to set initially and thecost of putting the initial shelf price tags would still remain as alower bound of the menu cost However for achieving more priceexibility by changing prices more frequently (ie multiple timeseach week) substantial changes must be undertaken At presentthe supermarket chains are set up to make the majority of theirprice changes on a weekly basis with the appropriate systems inplace to make this process most efcient For example in orderto save costs and to have higher quality price tags (eg withcolor more details greater clarity glossy etc) the chains oftensend new price tag requests to a printing shop which takes threedays to print and deliver the labels to each store Then giventhe large number of price changes taking place and the goals ofminimizing customer disruptions and labor costs (such as over-time pay) and coordinating with advertised price promotions theprices are changed in the store over a two-to-three-day period (seeTable VI) The combination of these schedule and built-in lags isacceptable under the current practice of changing prices weeklybut would have to be adjusted dramatically to allow for signifi-cantly more frequent price changes on a regular basis

Perhaps even more imposing are the costs of changing themanagerial costs associated with the current weekly system ofprice changes The process of pricing at this organizational levelis not a self-contained activity taking place in isolation from otheroperations of the supermarket management Rather it is a partof a larger system of business decisions and operations The cur-rent process of operations (such as data collection and theiranalysis management meetings coordination of the decisionsacross functional areas etc) is set up to function on a weeklybasis33 Further these management accounting and logisticssystems are currently built around a tremendous amount of in-

34 For example under the current system a chainwide category manageroperating at the corporate headquarters needs to study and assess numerouspieces of detailed information such as competitorsrsquo price and sale information fromthe last week the past weekrsquos sales at the own chain manufacturersupplier pro-motions wholesale price reductions coop allowances new product offerings shelfspace decisions coordination with newspaper advertising logistics at the ware-houses as well as at each store store differences in terms of customer characteris-tics and competitive environments productshelf selection and layout etc

35 If the supermarket chains indeed restructure the entire price change pro-cess and begin to change prices much more frequently (say two-to-three times aweek) on a regular basis then the shape of this cost function could change in anunpredictable way

V3 Relating Our Findings to the Existing Theoretical Models ofMenu Costs

In order to assess the magnitude of these menu cost guresin the context of the existing theoretical menu cost literatureconsider the following calculation experiments done within theframework of two theoretical menu cost models Blanchard andKiyotaki [1987] study a general equilibrium menu cost modelwith monopolistic competition and with unit elasticity of aggre-gate demand with respect to real money balances According totheir calculations menu costs of the magnitude of 008 percent ofrevenues which they consider ldquovery smallrdquo may be sufcient toprevent adjustment of prices Ball and Romer [1990] conductsimilar calculations in the framework of a model with imperfectcompetition and menu costs They nd that for plausible markupand labor elasticity parameter values menu costs needed to pre-vent price adjustment are 070 percent of revenues which as theysuggest are nonnegligible For smaller menu costs eg 004 per-cent of the revenue which Ball and Romer consider ldquotrivialrdquo im-plausibly large values of markup and labor elasticity parametersare needed to prevent price adjustment to monetary shocks

According to the gures in Table IV the reported menu costto revenues ratio for Chains AndashD averages 070 percent rangingfrom 061 percent to 076 percent These are signicantly largerthan the ldquotrivialrdquo 004 or 008 percent gures mentioned abovesuggesting that the menu cost gures we nd here are nontrivialFurther under the model and parameter values considered byBlanchard and Kiyotaki [1987] the menu cost gures we nd arehigher than the theoretical minimum needed to form a barrier toprice adjustments Under the model and parameter values con-sidered by Ball and Romer [1990] the reported menu costreve-nue ratio for all but one chain reaches or crosses the theoreticalthreshold of 070 needed to form a barrier to price adjustmentsThe existence of numerous unmeasured menu cost componentsdiscussed in subsection III5 also raises the possibility that theactual menu costs incurred by these chains are signicantlyhigher than that threshold This suggests that the menu costs wereport may be large enough to form a barrier to nominal priceadjustments when interpreted in the context of these models

An issue of interest in this literature is time-dependent ver-sus state-dependent pricing rules (see for example Caplin andLeahy [1991]) The evidence from our data set on the timing of

THE MAGNITUDE OF MENU COSTS 819

price changes suggests that the price change decisions in thesesupermarkets have a strong time-dependent price-setting ele-ment36 For example according to Table VI the prices in Chain Aare changed weekly according to the following schedule the pricechanges of general merchandise that is advertised is done Satur-day nights grocery and produce prices are changed Sundaynights the rest of the general merchandise prices are changed onMonday nights and the prices of advertised grocery items arechanged on Tuesday nights Thus as the gures in Table VI indi-cate over 96 percent of the price changes are done during Sundayand Monday nights However this does not imply that state-dependent pricing rules are unimportant Even if price changesacross product categories follow a prescheduled weekly time ta-ble the prices of which products to change is likely to be a state-dependent decision For example it could depend on changes insupply and demand conditions such as competitorsrsquo price changedecisions Indeed Levy Dutta and Bergen [1996] use retailstore-level orange juice price and cost data to demonstrate thatthe extent of price response to cost shocks that is the extent ofprice rigidity may depend on the nature of supply shocks37

We do not want to overstate the usefulness of our data fordirectly addressing the issue of monetary nonneutrality On onehand authors such as Caplin and Spulber [1987] have demon-strated that under certain conditions individual price rigiditymay not be sufcient for aggregate price rigidity but unfortu-nately our data do not speak directly to this issue38 On the otherhand authors such as Akerlof and Yellen [1985] Mankiw [1985]Parkin [1986] and Caplin and Leahy [1997] have shown that even

36 Danziger [1983] Caballero [1989] and Ball and Mankiw [1994] suggestthat time-dependent price adjustment of the type documented here can be optimalif the cost of gathering information about the state exceeds the cost of making theprice adjustment itself

37 We also considered the possibility of convexities in the cost of changingprices Our data do not suggest many convexities since the labor time spent inthe price tag change process the cost of printing and delivering price tags andin-store supervision time do not change with the size of a price change The onlymeasurable component of menu costs that could be convex is the cost of mistakesmade the larger the price change the higher the probability of a customer notic-ing the mistake and the larger the amount required to be refunded as compensa-tion Among the unmeasured components of menu cost the cost of corporatemanagerial time may increase with the size of a price change because larger pricechanges may require more serious consideration

38 Also see Balke and Wynne [1996] and Bryan and Cecchetti [1996] Sincewe do not have measures of how menu costs change over time our data also havelittle to say about time variation in menu costs or about the relationship betweenmenu costs and ination which during the period of the data collection (1991ndash1992) averaged about 3 percent annually

QUARTERLY JOURNAL OF ECONOMICS820

small menu costs can be relevant since they may be sufcient togenerate substantial aggregate nominal rigidity and thus largebusiness cycles Therefore as Blinder [1994] Kashyap [1995]and Slade [1996a] emphasize it is important to search for directevidence that such costs are indeed present at the micro level Bydirectly identifying documenting and measuring the magnitudeof menu costs at the store level we are taking an important stepin that direction

VI CONCLUSION AND FUTURE RESEARCH

Our main contribution is that we provide direct microeco-nomic evidence on the actual magnitude of menu costs for fourlarge U S retail supermarket chains The annual menu costs perstore at these chains average $105887 comprising 070 percentof revenues 352 percent of net prot margins and $052 perprice change on average

Further we provide evidence which suggests that thesemenu costs may be forming a barrier to price changes Specifi-cally we show that (1) supermarket chains not subject to itempricing law change prices two and a half times more frequentlythan the chain that is subject to the law (2) within the chain thatis subject to the item pricing law they change prices over threetimes as frequently for products that are exempt from this lawthan for the products which are subject to this law and (3) wend that these chains do not adjust prices of up to one-third ofthe products for which they face cost increases because of menucost considerations

When we relate these ndings to the existing theoreticalmodels of menu costs we conclude that the magnitude of menucosts we nd is large enough to be capable of having macroeco-nomic signicance Specically when considered in the context ofthe theoretical menu cost models of Blanchard and Kiyotaki[1987] and Ball and Romer [1990] we nd that the menu costgures we report are ldquonontrivialrdquo and their relative magnitudescross the minimum theoretical threshold needed to form a barrierto price adjustments

Despite the high relative magnitude of the marginal cost ofchanging price that we found the data still indicate frequentweekly price changes This is because of the high marginal bene-t of changing price which is due to the erce competition foundin the retail supermarket industry That marginal benets may

THE MAGNITUDE OF MENU COSTS 821

outweigh the marginal costs of changing prices in this industryhowever does not rule out the possibility that menu costs of themagnitude we nd here can create substantial nominal rigidityin other industries or markets In less competitive industries andmarkets menu costs of the type and magnitude we documenthere are likely to have a bigger impact on the frequency of priceadjustment and consequently on the degree of price rigidity

At a minimum the direct dollar measures of menu costs wereport here can be used as a starting point for future research onmeasuring their magnitude in other industries and establish-ments We anticipate that these menu costs will be similar inother markets which rely on posted prices (such as drugstoresdepartment stores etc) because the steps involved in the pricechange process are likely to be similar What may differ are thefrequency of price changes and the labor wage rates at thesestores For example since supermarket chains change thousandsof prices each week the total annual menu costs incurred bythese chains per store are likely to be high in comparison to otherretail formats such as chain drugstores or department storesThere are however a variety of industries for which the stepsinvolved in changing prices would be signicantly different fromthose reported in our study For example business-to-businesssales which often rely on a sales force will require changes in thelist price sheets changes in the instructions to the sales forcewhich may include education and discussion with the salespeoplein the company and so forth These business-to-business pricesalso often have more complex pricing schemes including quantitydiscounts bundling and individually negotiated prices As an-other example the composition of the cost of changing the news-stand prices of magazines [Cecchetti 1986] or the prices ofproducts sold through catalogs [Kashyap 1995] are different frommany of the menu cost components we discuss here Further thending that a centralization of pricing decisions makes the store-level managerial component of menu cost relatively small sug-gests that the managerial menu costs likely are highest insettings where price change decisions are decentralized Thus fu-ture empirical work should look at menu cost and its compositionin a variety of other industries markets and products with bothcentralized as well as decentralized price change decisions in or-der to see whether the magnitude of these costs can be general-ized and benchmarks can be established Further there aretechnological changes taking place in this and other industries

that promise to alter the structure of menu costs which deserveattention At the theoretical level our ndings suggest that it maybe worthwhile to explore models which incorporate the idea ofitem pricing laws as an additional component of menu costs

THE MAGNITUDE OF MENU COSTS 825

the supermarket chains we study prices are generally set at cor-porate headquarters in a weekly meeting where the manager incharge of setting prices looks at a variety of information including(a) any manufacturer wholesale price changes promotions andother related issues (b) past sales for this product and (c) com-petitorsrsquo prices Based on this information and on discussionswith other managers the price-setting manager decides whetherto change prices and if so by how much

To estimate the magnitude of these managerial componentsof the menu costs consider the following In an average chainthere is at least one executive of merchandising who devotesmost of hisher time to pricing decisions In addition there areup to three senior managers who would deal with pricing andto whom category managers report There are also ten-to-twelvecategory managers who are responsible for setting prices on allthe products within their category An additional two-to-fourpeople spend full time handling the implementation of pricechanges across retail outlets coordinating the printing and deliv-ery of price tags and handling pricing problems in the systemAnother ve-to-seven workers gather the data on competitorsrsquoprices and analyse both the competitorsrsquo data and the storersquos ownscanner data to put it in a form useable by managers makingpricing decisions Thus in total there are about 21ndash27 peopleworking at the corporate headquarters on price change decisionsAssuming $150000 as the average annual salary of the executiveof merchandising and senior managers $100000 for categorymanagers and $50000 for the rest the chainwide managerialcost falls in the neighborhood of $23ndash$29 million a year whichseems a substantial amount However note that these pricing de-cision are made for the entire chain and therefore the costs perstore are signicantly less especially for the larger chains Forexample using $29 million as the upper bound the additionalannual menu cost per store for Chains AndashD which on averageoperate about 400 stores each averages about $7250 which ismuch lower than expected and is due to the centralization of theprice change decisions in the chains we study17

signed to save the costs of corporate headquarter managerial time spent on pricechange decisions the ESL company did not measure this component of menucosts The estimates reported in this section are based on the information receivedfrom the ESL company executives

17 A decentralization of the price change process say by allowing the store-level managers to make price change decisions can change these gures tremen-dously For example consider the following thought experiment conducted using

QUARTERLY JOURNAL OF ECONOMICS808

Our menu cost measures also do not include the cost ofchanging prices of direct store delivery (DSD) products Theseproducts are almost completely handled by manufacturers in-cluding stocking monitoring inventories and setting and chang-ing prices18 We have data on the weekly frequency of pricechanges of DSD products in Chain E In an average week thereare 174 price changes of DSD products which is about 10 percentof the supermarketrsquos total weekly price changes Using the costof changing the price of a regular product $133 (see Section IVfor details) the annual cost of changing prices of the DSD prod-ucts in this chain roughly equals $1203419 Our menu cost mea-sures do not include these gures since we do not have similardata for the other chains20

III6 Total Menu Costs

The total annual menu costs reported for each chain perstore are listed in the last row of Table III As the table indicatesthe menu costs range from $91416 to $114188 for an average of$105887 per store per year21 Note that these menu cost mea-

the average annual per store gures for Chains AndashD Suppose that the supermar-ket chains decentralize the price change process by hiring for each store only one-quarter of the price change managing team while at the same time they com-pletely eliminate the corporate level team The resulting annual menu cost perstore would be $830887 ( 5 $105887 1 $725000) which would dwarf any of themeasurable menu cost gures we report in this study Even if the average storeonly hired just the merchandising manager at the annual cost of $150000 itwould still incur annual managerial cost of about $255887 ( 5 $105887 1$150000) In other words such a trivial decentralization would double the store-level menu costs This would indeed make the cost of price change decisions themost important component of menu cost

18 DSD products usually are high-volume fast-moving or perishable prod-ucts such as milk soda eggs bread dairy snacks etc In the chains we studyabout 10ndash20 percent of the products are of a DSD type but that share may reachas much as 40 percent of the products carried [Direct Store Delivery Work Groupet al 1995]

19 The process of changing prices of DSD and of regular products is similarBut with DSD products there are additional costs of the time spent on driving tothe store parking and setting up the price change process at each store

20 Our measures of menu cost also do not incorporate the cost of informingconsumers about price changes which can take a variety of forms such as newspa-per ads and inserts TV and radio ads in-store promotion signs etc Finally wehave no data on lost customer goodwill and damaged reputation caused by dis-crepancies between price tag and cash register [Okun 1981 Carlton and Perloff1994 Haddock and McChesney 1994]

21 The variation in the menu costs across the chains is mostly due to wagerate and labor-efciency variations Also note that since the supermarket chainsin our sample are similar in the size of their stores carry similar sets of productsand follow similar processes of price change and price change decisions it is rea-sonable to believe that the chains incur similar types of costs Therefore as notedunderneath Table III these menu cost measures are computed by replacing theunreported gures by the averages of the available values from the other chains

THE MAGNITUDE OF MENU COSTS 809

sures include only the components we could accurately measurein dollar terms which are discussed in subsections III1ndashIII4

IV ITEM PRICING LAWS AND MENU COSTS

In this section we provide evidence on the menu costs for anadditional chain (Chain E) which unlike the other four chainsoperates in a state with an item pricing law The most importantaspect of item pricing laws is that they require a price tag on eachindividual item sold not just on the shelf which is what the otherfour chains in our sample do For example the item pricing lawin Connecticut requires that the grocers ldquoshall mark or cause tobe marked each consumer commodity which bears a UniversalProduct Code with its retail pricerdquo 22 From a menu cost perspec-tive the requirement of posting prices on every item (in additionto the shelf price tag) introduces additional costs in the processof changing prices

Although most of the steps involved in changing prices arethe same for both types of chains stores that are subject to itempricing laws have to undertake additional steps to obey this law23

The labor cost component of menu costs in Chain E totals $75127a year of which $49710 is the cost of the labor time spent onchanging the prices of individual items $3234 is the cost of thelabor time spent on shelf tag replacements and $22183 is thecost of the labor time spent on sign changes (see Table III)24 Anadditional $44168 is spent annually putting prices on new itemsas they are brought to the shelves Although we do not includethis last gure in our menu cost measures because we do not haveinformation on how much of it is due to price change activity andhow much due to just pricingmdashthese costs are clearly a directconsequence of the item pricing law The printing and deliverycost of price tags and price signs are $7644 and the mistake

22 Public Act No 75ndash391 An Act Concerning Pricing of Consumer Merchan-dise [Public Acts of the State of Connecticut 1975 Vol 1 p 390]

23 These steps which are in addition to the regular steps undertaken toreplace price tags on the shelves include (1) obtaining item price tags (2) settingup workstations (3) locating the product (4) removing an item from the shelf (5)removing old price tag (6) setting marking gun (7) applying new price tag and(8) returning the item back to the shelf

24 Since we do not have a measure of the cost of labor time spent on signchanges and the cost of in-store managerial supervision time for this chain weuse the average of the chains that report them (A and D) Note also that thehourly wage rate of $907 paid by Chain E is lower than the hourly wage of about$1400ndash$2000 paid by Chains AndashD

QUARTERLY JOURNAL OF ECONOMICS810

25 Further note that the chains with smaller menu costs are likely tochange their prices more frequently which suggests that the gures of the totalannual menu costs understate the differences between Chain E and the otherchains Indeed despite the large difference in the menu cost per price change thetotal annual menu costs per store for Chain E ($109036) are more comparable tothose of Chains AndashD ($105887)

26 In calculations that follow we use industry averages because (1) thechains did not share this proprietary information with us and (2) we were re-quired to keep the identity of these chains condential as some of these numbersare detailed enough to enable some readers to identify the chains under study

costs are $20799 These gures along with the amount of $5466for the cost of in-store managerial supervision time yield totalannual menu costs of $109036 per store

Although the magnitude of the total annual menu costs seemsimilar to the other four chains note that the average weeklyfrequency of price changes in Chain E is only 1578 which is only403 ( 5 15783916) percent of the price changes made by theother four chains Thus the average menu cost per price changefor Chain E is $133 (see Table IV last row) In contrast the corre-sponding gures for Chains AndashD average $052 Hence the menucosts per price change incurred by the supermarket chain facingitem pricing laws are more than two and a half times the amountincurred by chains that are not subject to this law25 Overallthese ndings suggest that legal restrictions of the type of itempricing laws can have a signicant impact on the menu costs in-curred by sellers

V SIGNIFICANCE OF THE MENU COSTS

The next natural question to ask is how important are thesecosts To address this question we (1) provide several relativemeasures of the menu costs (2) discuss the effect of the menucosts on supermarketsrsquo price change activity and (3) discuss mac-roeconomic implications by relating our ndings to the existingtheoretical models of menu costs In each case we provide addi-tional evidence to help assess the importance of these menu costs

V1 Relative Measures of the Menu Costs

In order to assess the relative magnitude of the menu costsreported in Section IV we now present the menu cost gures rela-tive to the average store-level revenues and net prot margins26

In addition we present the menu cost gures per price changeThe annual average revenues of a large U S supermarket

chain of the type and size included in our sample is $15052716

per store27 According to the second row of Table IV the ratio ofmenu costs to revenues for Chains AndashD ranges between 061ndash076percent averaging 070 percent28 We relate the size of thesegures to the existing theoretical menu cost models in sub-section V3

Net prot margin which measures the revenues minus allcosts is approximately 1ndash3 percent of revenues for these chains[Montgomery 1994] so we use 2 percent as a working averageThe reason for the low prot rate in this industry is the intensecompetition [Calatone et al 1989] especially at the regional level[Chevalier 1995] which has been increasing since the early 1990s[Progressive Grocer November 1992 p 50] It follows that theaverage store protability for these chains equals $301054 peryear Therefore the ratio of total menu cost to net margin forChains AndashD ranges between 304ndash379 percent for an average of352 percent Thus the menu costs we report in this study repre-sent a signicant share of supermarketsrsquo prots

Another way to look at the menu cost gures we report is toexpress them relative to the frequency of price changes In thelast row of Table IV we present the menu cost gures per pricechange for each chain As the table indicates the cost of changinga price in Chains AndashD ranges between $046ndash$068 for an averageof $052 For Chain E the gure is substantially larger $133 perprice change29 These gures are lower than the estimated cost of

27 This is the average of two different estimates $12945432 and$17160000 The source of the rst gure is internal record of a supermarketchain of the type and size studied here The second gure comes from Supermar-ket Business [1993 p 52]

28 We also measured the menu costs in terms of controllable operating ex-penses (which are the portion of costs that the retailer has direct control over andtherefore are often the costs that the retailer is most focused on managing) andgross margins (which measure the supermarket revenues minus direct cost of theproducts it sells) We nd that the menu costs comprise 313 percent of controlla-ble operating expenses and 281 percent of gross margins at these chains on aver-age Finally if we measure the menu costs relative to the number of productscarried per store (about 25000) then we nd that the menu costs per productaverage $423 for Chains AndashD See Table IV and its footnotes for details

29 We can also try to express the menu cost gures relative to the numberof individual items sold by these chains each year (Note the difference betweennumber of products carried and number of items sold As an example a TartarControl Crest 8oz would be considered a product carried and 300 units of themsold per year would be considered number of items sold) Using $170 as the aver-age price of all the products sold we nd that the menu cost per item sold for thefour chains is in the range of $00103ndash$00129 for an average of $00119 (see TableIV second to last row) To see the relative magnitude of these gures note thataccording to Berkowitz Kerin and Rudelius [1986 p 319] the goal of the super-market chains of the type we study ldquo is to make 1 penny of prot on each dollarof salesrdquo Thus menu cost per item sold when adjusted for the average price

THE MAGNITUDE OF MENU COSTS 813

$200ndash$300 per price change reported by Slade [1996a] Thereare several possible reasons for this (1) our menu cost gures arebased on actual measurements of the resources that go into theprice change process whereas she estimates menu costs econo-metrically as model coefcients using a mix of store-level priceand aggregate cost data (2) we cover 25000 products that thesupermarkets carry rather than a single product category (3) ourmenu cost gures do not include all components of menu costsand (4) there could be differences in wage rates that may be im-portant given the signicance of the labor cost component inmenu costs

V2 The Effect of Menu Costs on the Price Change Activity of theSupermarkets

In this section we present evidence which suggests that thesemenu costs may be forming a barrier to price change activity Tobegin with consider the effect of the item pricing law on the pricechange activity of Chain E The data on the weekly frequency ofprice changes in each chain are displayed in the last two rows ofTable I According to these gures the average weekly frequencyof price changes in Chain E is only 1578 Thus on average ChainE changes the prices of only 631 percent of its products eachweek In contrast the average weekly frequency of price changesat Chains AndashD ranges from 3223 to 4316 for the four-chain aver-age of 3916 price changes weekly So Chains AndashD change priceson 1289 to 1726 percent of their products each week yielding afour-chain average of 1566 percent Thus Chain E which facesthe item pricing law changes prices only about one-third timesas frequently as do Chains AndashD30

Moreover within Chain E there are 400 products that areexempt from the item pricing law and thereby face lower menucosts We nd that there are an average of 83 weekly pricechanges for these products yielding 21 percent of these productschanging prices So within Chain E they change prices over threetimes as frequently for products with lower menu costs than for

roughly equals one-half of their target net prot per item which seemssubstantial

30 However note that our comparison of the two types of chains may not becompletely ceteris paribus because these stores are located in different states andtherefore there may be other chain-specic factors (in addition to item pricinglaws) that distinguish these stores We do not have any specic information onthese differences We do know however that the stores in these chains are similarin size and carry similar sets of products

QUARTERLY JOURNAL OF ECONOMICS814

the products with higher menu costs Note that this nding is onthe price change activity within the same chain offering almost anatural experiment on the impact of menu costs on the chainrsquospricing behavior Hence we provide evidence both across chainsas well as across products within a chain that as the costs ofchanging price go up the frequency of price changes goes downThus the menu costs we nd are signicant enough to affect thechainrsquos price change practice

We also have additional evidence from Chains A B and Dabout these menu costs being a barrier to certain price changesand it is summarized in Table V According to the Price Manage-ment Department of Chain A the chain experiences cost in-creases on 860 products in an average week to which it wouldlike to react with a price increase31 However on average 22 per-cent of these price increases are not implemented immediatelybecause the cost of changing prices for these products is too highto make it economically worthwhile Figures of the same magni-tude were reported by other chains For example Chain D experi-ences cost increases for 961 products in an average week Out ofthese the chain adjusts prices of only 633 products The re-maining 34 percent of the prices are left unadjusted because ofthe menu costs Similarly Chain B nds it economically ineffi-cient to adjust prices of 508 ie 30 percent of its products eachweek because of menu costs This provides additional evidencethat the menu costs incurred by these chains are preventing priceadjustments to some costs changes leading to price rigidities ofthe products involved32 Note that although we do not have simi-lar data for Chain E we would expect signicantly lower num-bers on this measure at that chain These gures also suggest anupper bound on the benet of complete price exibility under thecurrent pricing practice of weekly price adjustments Howeverif new technologies (eg ESL systems) and new pricing prac-tices (eg a decentralization of the price change decisions) are

31 Our data contain information only on the frequency of cost increasesAlthough it is more than likely that the supermarkets are experiencing cost de-creases as well our data set contained no information on such decreases

32 Menu costs may even be playing a role in the observed movement towardpricing strategies that rely on fewer price changes such as EDLP [Blattberg andNeslin 1989 Lattin and Ortmeyer 1991 Marketing News April 13 1992 p 8]According to Progressive Grocer [November 1992 p 50] ldquoA growing number ofoperators say they have switched from high-low pricing [to EDLP] They cite theinefciencies of making frequent price changes rdquo Similarly Hoch Dreze andPurk [1994 p 16] state that EDLP lowers operating costs by lowering ldquo in-store labor costs because of less frequent changeovers in special displaysrdquo

adopted allowing a fundamental change in the way the pricingmechanism is currently set the managers could consider morefrequent price change activity (eg multiple times each week) asmenu costs go down

In this paper we measure the menu costs at the chainsrsquo cur-rent level of price change activity It may be worthwhile to specu-late on the shape of the cost function relating menu costs to thefrequency of price changes by assessing how these costs wouldchange if the price change activity were to increase or to decreaseIt seems likely that many of the costs we report in this paper will(approximately) change linearly with additional price changeswithin the current range of price changes the chains are under-taking (plus or minus perhaps a thousand per week) For ex-ample the labor costs associated with changing a shelf price tagcosts of verifying price changes and the costs of mistakes oc-curring during this process all increase linearly with the fre-quency of price changes This is because most of the time-consuming steps involved in the price change process must berepeated each time an additional shelf price tag is changed (seeTable II) Further we were unable to nd many tasks that gener-ated signicant returns to scale It is unclear what cost savingsare available if the price change activity drops substantially be-

QUARTERLY JOURNAL OF ECONOMICS816

low the levels it is at now Clearly if price changes were nearzero or done less frequently than weekly (say monthly) therecould be major differences in these costs

What is less clear is how these costs would change at moreextreme levels of price change activity With less frequent pricechanges the menu costs could probably be reduced signicantlyalthough the cost of deciding what prices to set initially and thecost of putting the initial shelf price tags would still remain as alower bound of the menu cost However for achieving more priceexibility by changing prices more frequently (ie multiple timeseach week) substantial changes must be undertaken At presentthe supermarket chains are set up to make the majority of theirprice changes on a weekly basis with the appropriate systems inplace to make this process most efcient For example in orderto save costs and to have higher quality price tags (eg withcolor more details greater clarity glossy etc) the chains oftensend new price tag requests to a printing shop which takes threedays to print and deliver the labels to each store Then giventhe large number of price changes taking place and the goals ofminimizing customer disruptions and labor costs (such as over-time pay) and coordinating with advertised price promotions theprices are changed in the store over a two-to-three-day period (seeTable VI) The combination of these schedule and built-in lags isacceptable under the current practice of changing prices weeklybut would have to be adjusted dramatically to allow for signifi-cantly more frequent price changes on a regular basis

Perhaps even more imposing are the costs of changing themanagerial costs associated with the current weekly system ofprice changes The process of pricing at this organizational levelis not a self-contained activity taking place in isolation from otheroperations of the supermarket management Rather it is a partof a larger system of business decisions and operations The cur-rent process of operations (such as data collection and theiranalysis management meetings coordination of the decisionsacross functional areas etc) is set up to function on a weeklybasis33 Further these management accounting and logisticssystems are currently built around a tremendous amount of in-

35 If the supermarket chains indeed restructure the entire price change pro-cess and begin to change prices much more frequently (say two-to-three times aweek) on a regular basis then the shape of this cost function could change in anunpredictable way

V3 Relating Our Findings to the Existing Theoretical Models ofMenu Costs

In order to assess the magnitude of these menu cost guresin the context of the existing theoretical menu cost literatureconsider the following calculation experiments done within theframework of two theoretical menu cost models Blanchard andKiyotaki [1987] study a general equilibrium menu cost modelwith monopolistic competition and with unit elasticity of aggre-gate demand with respect to real money balances According totheir calculations menu costs of the magnitude of 008 percent ofrevenues which they consider ldquovery smallrdquo may be sufcient toprevent adjustment of prices Ball and Romer [1990] conductsimilar calculations in the framework of a model with imperfectcompetition and menu costs They nd that for plausible markupand labor elasticity parameter values menu costs needed to pre-vent price adjustment are 070 percent of revenues which as theysuggest are nonnegligible For smaller menu costs eg 004 per-cent of the revenue which Ball and Romer consider ldquotrivialrdquo im-plausibly large values of markup and labor elasticity parametersare needed to prevent price adjustment to monetary shocks

According to the gures in Table IV the reported menu costto revenues ratio for Chains AndashD averages 070 percent rangingfrom 061 percent to 076 percent These are signicantly largerthan the ldquotrivialrdquo 004 or 008 percent gures mentioned abovesuggesting that the menu cost gures we nd here are nontrivialFurther under the model and parameter values considered byBlanchard and Kiyotaki [1987] the menu cost gures we nd arehigher than the theoretical minimum needed to form a barrier toprice adjustments Under the model and parameter values con-sidered by Ball and Romer [1990] the reported menu costreve-nue ratio for all but one chain reaches or crosses the theoreticalthreshold of 070 needed to form a barrier to price adjustmentsThe existence of numerous unmeasured menu cost componentsdiscussed in subsection III5 also raises the possibility that theactual menu costs incurred by these chains are signicantlyhigher than that threshold This suggests that the menu costs wereport may be large enough to form a barrier to nominal priceadjustments when interpreted in the context of these models

An issue of interest in this literature is time-dependent ver-sus state-dependent pricing rules (see for example Caplin andLeahy [1991]) The evidence from our data set on the timing of

THE MAGNITUDE OF MENU COSTS 819

price changes suggests that the price change decisions in thesesupermarkets have a strong time-dependent price-setting ele-ment36 For example according to Table VI the prices in Chain Aare changed weekly according to the following schedule the pricechanges of general merchandise that is advertised is done Satur-day nights grocery and produce prices are changed Sundaynights the rest of the general merchandise prices are changed onMonday nights and the prices of advertised grocery items arechanged on Tuesday nights Thus as the gures in Table VI indi-cate over 96 percent of the price changes are done during Sundayand Monday nights However this does not imply that state-dependent pricing rules are unimportant Even if price changesacross product categories follow a prescheduled weekly time ta-ble the prices of which products to change is likely to be a state-dependent decision For example it could depend on changes insupply and demand conditions such as competitorsrsquo price changedecisions Indeed Levy Dutta and Bergen [1996] use retailstore-level orange juice price and cost data to demonstrate thatthe extent of price response to cost shocks that is the extent ofprice rigidity may depend on the nature of supply shocks37

We do not want to overstate the usefulness of our data fordirectly addressing the issue of monetary nonneutrality On onehand authors such as Caplin and Spulber [1987] have demon-strated that under certain conditions individual price rigiditymay not be sufcient for aggregate price rigidity but unfortu-nately our data do not speak directly to this issue38 On the otherhand authors such as Akerlof and Yellen [1985] Mankiw [1985]Parkin [1986] and Caplin and Leahy [1997] have shown that even

36 Danziger [1983] Caballero [1989] and Ball and Mankiw [1994] suggestthat time-dependent price adjustment of the type documented here can be optimalif the cost of gathering information about the state exceeds the cost of making theprice adjustment itself

37 We also considered the possibility of convexities in the cost of changingprices Our data do not suggest many convexities since the labor time spent inthe price tag change process the cost of printing and delivering price tags andin-store supervision time do not change with the size of a price change The onlymeasurable component of menu costs that could be convex is the cost of mistakesmade the larger the price change the higher the probability of a customer notic-ing the mistake and the larger the amount required to be refunded as compensa-tion Among the unmeasured components of menu cost the cost of corporatemanagerial time may increase with the size of a price change because larger pricechanges may require more serious consideration

38 Also see Balke and Wynne [1996] and Bryan and Cecchetti [1996] Sincewe do not have measures of how menu costs change over time our data also havelittle to say about time variation in menu costs or about the relationship betweenmenu costs and ination which during the period of the data collection (1991ndash1992) averaged about 3 percent annually

QUARTERLY JOURNAL OF ECONOMICS820

small menu costs can be relevant since they may be sufcient togenerate substantial aggregate nominal rigidity and thus largebusiness cycles Therefore as Blinder [1994] Kashyap [1995]and Slade [1996a] emphasize it is important to search for directevidence that such costs are indeed present at the micro level Bydirectly identifying documenting and measuring the magnitudeof menu costs at the store level we are taking an important stepin that direction

VI CONCLUSION AND FUTURE RESEARCH

Our main contribution is that we provide direct microeco-nomic evidence on the actual magnitude of menu costs for fourlarge U S retail supermarket chains The annual menu costs perstore at these chains average $105887 comprising 070 percentof revenues 352 percent of net prot margins and $052 perprice change on average

Further we provide evidence which suggests that thesemenu costs may be forming a barrier to price changes Specifi-cally we show that (1) supermarket chains not subject to itempricing law change prices two and a half times more frequentlythan the chain that is subject to the law (2) within the chain thatis subject to the item pricing law they change prices over threetimes as frequently for products that are exempt from this lawthan for the products which are subject to this law and (3) wend that these chains do not adjust prices of up to one-third ofthe products for which they face cost increases because of menucost considerations

When we relate these ndings to the existing theoreticalmodels of menu costs we conclude that the magnitude of menucosts we nd is large enough to be capable of having macroeco-nomic signicance Specically when considered in the context ofthe theoretical menu cost models of Blanchard and Kiyotaki[1987] and Ball and Romer [1990] we nd that the menu costgures we report are ldquonontrivialrdquo and their relative magnitudescross the minimum theoretical threshold needed to form a barrierto price adjustments

Despite the high relative magnitude of the marginal cost ofchanging price that we found the data still indicate frequentweekly price changes This is because of the high marginal bene-t of changing price which is due to the erce competition foundin the retail supermarket industry That marginal benets may

THE MAGNITUDE OF MENU COSTS 821

outweigh the marginal costs of changing prices in this industryhowever does not rule out the possibility that menu costs of themagnitude we nd here can create substantial nominal rigidityin other industries or markets In less competitive industries andmarkets menu costs of the type and magnitude we documenthere are likely to have a bigger impact on the frequency of priceadjustment and consequently on the degree of price rigidity

At a minimum the direct dollar measures of menu costs wereport here can be used as a starting point for future research onmeasuring their magnitude in other industries and establish-ments We anticipate that these menu costs will be similar inother markets which rely on posted prices (such as drugstoresdepartment stores etc) because the steps involved in the pricechange process are likely to be similar What may differ are thefrequency of price changes and the labor wage rates at thesestores For example since supermarket chains change thousandsof prices each week the total annual menu costs incurred bythese chains per store are likely to be high in comparison to otherretail formats such as chain drugstores or department storesThere are however a variety of industries for which the stepsinvolved in changing prices would be signicantly different fromthose reported in our study For example business-to-businesssales which often rely on a sales force will require changes in thelist price sheets changes in the instructions to the sales forcewhich may include education and discussion with the salespeoplein the company and so forth These business-to-business pricesalso often have more complex pricing schemes including quantitydiscounts bundling and individually negotiated prices As an-other example the composition of the cost of changing the news-stand prices of magazines [Cecchetti 1986] or the prices ofproducts sold through catalogs [Kashyap 1995] are different frommany of the menu cost components we discuss here Further thending that a centralization of pricing decisions makes the store-level managerial component of menu cost relatively small sug-gests that the managerial menu costs likely are highest insettings where price change decisions are decentralized Thus fu-ture empirical work should look at menu cost and its compositionin a variety of other industries markets and products with bothcentralized as well as decentralized price change decisions in or-der to see whether the magnitude of these costs can be general-ized and benchmarks can be established Further there aretechnological changes taking place in this and other industries

that promise to alter the structure of menu costs which deserveattention At the theoretical level our ndings suggest that it maybe worthwhile to explore models which incorporate the idea ofitem pricing laws as an additional component of menu costs

THE MAGNITUDE OF MENU COSTS 825

Our menu cost measures also do not include the cost ofchanging prices of direct store delivery (DSD) products Theseproducts are almost completely handled by manufacturers in-cluding stocking monitoring inventories and setting and chang-ing prices18 We have data on the weekly frequency of pricechanges of DSD products in Chain E In an average week thereare 174 price changes of DSD products which is about 10 percentof the supermarketrsquos total weekly price changes Using the costof changing the price of a regular product $133 (see Section IVfor details) the annual cost of changing prices of the DSD prod-ucts in this chain roughly equals $1203419 Our menu cost mea-sures do not include these gures since we do not have similardata for the other chains20

III6 Total Menu Costs

The total annual menu costs reported for each chain perstore are listed in the last row of Table III As the table indicatesthe menu costs range from $91416 to $114188 for an average of$105887 per store per year21 Note that these menu cost mea-

the average annual per store gures for Chains AndashD Suppose that the supermar-ket chains decentralize the price change process by hiring for each store only one-quarter of the price change managing team while at the same time they com-pletely eliminate the corporate level team The resulting annual menu cost perstore would be $830887 ( 5 $105887 1 $725000) which would dwarf any of themeasurable menu cost gures we report in this study Even if the average storeonly hired just the merchandising manager at the annual cost of $150000 itwould still incur annual managerial cost of about $255887 ( 5 $105887 1$150000) In other words such a trivial decentralization would double the store-level menu costs This would indeed make the cost of price change decisions themost important component of menu cost

18 DSD products usually are high-volume fast-moving or perishable prod-ucts such as milk soda eggs bread dairy snacks etc In the chains we studyabout 10ndash20 percent of the products are of a DSD type but that share may reachas much as 40 percent of the products carried [Direct Store Delivery Work Groupet al 1995]

19 The process of changing prices of DSD and of regular products is similarBut with DSD products there are additional costs of the time spent on driving tothe store parking and setting up the price change process at each store

20 Our measures of menu cost also do not incorporate the cost of informingconsumers about price changes which can take a variety of forms such as newspa-per ads and inserts TV and radio ads in-store promotion signs etc Finally wehave no data on lost customer goodwill and damaged reputation caused by dis-crepancies between price tag and cash register [Okun 1981 Carlton and Perloff1994 Haddock and McChesney 1994]

21 The variation in the menu costs across the chains is mostly due to wagerate and labor-efciency variations Also note that since the supermarket chainsin our sample are similar in the size of their stores carry similar sets of productsand follow similar processes of price change and price change decisions it is rea-sonable to believe that the chains incur similar types of costs Therefore as notedunderneath Table III these menu cost measures are computed by replacing theunreported gures by the averages of the available values from the other chains

THE MAGNITUDE OF MENU COSTS 809

sures include only the components we could accurately measurein dollar terms which are discussed in subsections III1ndashIII4

IV ITEM PRICING LAWS AND MENU COSTS

In this section we provide evidence on the menu costs for anadditional chain (Chain E) which unlike the other four chainsoperates in a state with an item pricing law The most importantaspect of item pricing laws is that they require a price tag on eachindividual item sold not just on the shelf which is what the otherfour chains in our sample do For example the item pricing lawin Connecticut requires that the grocers ldquoshall mark or cause tobe marked each consumer commodity which bears a UniversalProduct Code with its retail pricerdquo 22 From a menu cost perspec-tive the requirement of posting prices on every item (in additionto the shelf price tag) introduces additional costs in the processof changing prices

Although most of the steps involved in changing prices arethe same for both types of chains stores that are subject to itempricing laws have to undertake additional steps to obey this law23

The labor cost component of menu costs in Chain E totals $75127a year of which $49710 is the cost of the labor time spent onchanging the prices of individual items $3234 is the cost of thelabor time spent on shelf tag replacements and $22183 is thecost of the labor time spent on sign changes (see Table III)24 Anadditional $44168 is spent annually putting prices on new itemsas they are brought to the shelves Although we do not includethis last gure in our menu cost measures because we do not haveinformation on how much of it is due to price change activity andhow much due to just pricingmdashthese costs are clearly a directconsequence of the item pricing law The printing and deliverycost of price tags and price signs are $7644 and the mistake

22 Public Act No 75ndash391 An Act Concerning Pricing of Consumer Merchan-dise [Public Acts of the State of Connecticut 1975 Vol 1 p 390]

23 These steps which are in addition to the regular steps undertaken toreplace price tags on the shelves include (1) obtaining item price tags (2) settingup workstations (3) locating the product (4) removing an item from the shelf (5)removing old price tag (6) setting marking gun (7) applying new price tag and(8) returning the item back to the shelf

24 Since we do not have a measure of the cost of labor time spent on signchanges and the cost of in-store managerial supervision time for this chain weuse the average of the chains that report them (A and D) Note also that thehourly wage rate of $907 paid by Chain E is lower than the hourly wage of about$1400ndash$2000 paid by Chains AndashD

QUARTERLY JOURNAL OF ECONOMICS810

25 Further note that the chains with smaller menu costs are likely tochange their prices more frequently which suggests that the gures of the totalannual menu costs understate the differences between Chain E and the otherchains Indeed despite the large difference in the menu cost per price change thetotal annual menu costs per store for Chain E ($109036) are more comparable tothose of Chains AndashD ($105887)

26 In calculations that follow we use industry averages because (1) thechains did not share this proprietary information with us and (2) we were re-quired to keep the identity of these chains condential as some of these numbersare detailed enough to enable some readers to identify the chains under study

costs are $20799 These gures along with the amount of $5466for the cost of in-store managerial supervision time yield totalannual menu costs of $109036 per store

Although the magnitude of the total annual menu costs seemsimilar to the other four chains note that the average weeklyfrequency of price changes in Chain E is only 1578 which is only403 ( 5 15783916) percent of the price changes made by theother four chains Thus the average menu cost per price changefor Chain E is $133 (see Table IV last row) In contrast the corre-sponding gures for Chains AndashD average $052 Hence the menucosts per price change incurred by the supermarket chain facingitem pricing laws are more than two and a half times the amountincurred by chains that are not subject to this law25 Overallthese ndings suggest that legal restrictions of the type of itempricing laws can have a signicant impact on the menu costs in-curred by sellers

V SIGNIFICANCE OF THE MENU COSTS

The next natural question to ask is how important are thesecosts To address this question we (1) provide several relativemeasures of the menu costs (2) discuss the effect of the menucosts on supermarketsrsquo price change activity and (3) discuss mac-roeconomic implications by relating our ndings to the existingtheoretical models of menu costs In each case we provide addi-tional evidence to help assess the importance of these menu costs

V1 Relative Measures of the Menu Costs

In order to assess the relative magnitude of the menu costsreported in Section IV we now present the menu cost gures rela-tive to the average store-level revenues and net prot margins26

In addition we present the menu cost gures per price changeThe annual average revenues of a large U S supermarket

chain of the type and size included in our sample is $15052716

per store27 According to the second row of Table IV the ratio ofmenu costs to revenues for Chains AndashD ranges between 061ndash076percent averaging 070 percent28 We relate the size of thesegures to the existing theoretical menu cost models in sub-section V3

Net prot margin which measures the revenues minus allcosts is approximately 1ndash3 percent of revenues for these chains[Montgomery 1994] so we use 2 percent as a working averageThe reason for the low prot rate in this industry is the intensecompetition [Calatone et al 1989] especially at the regional level[Chevalier 1995] which has been increasing since the early 1990s[Progressive Grocer November 1992 p 50] It follows that theaverage store protability for these chains equals $301054 peryear Therefore the ratio of total menu cost to net margin forChains AndashD ranges between 304ndash379 percent for an average of352 percent Thus the menu costs we report in this study repre-sent a signicant share of supermarketsrsquo prots

Another way to look at the menu cost gures we report is toexpress them relative to the frequency of price changes In thelast row of Table IV we present the menu cost gures per pricechange for each chain As the table indicates the cost of changinga price in Chains AndashD ranges between $046ndash$068 for an averageof $052 For Chain E the gure is substantially larger $133 perprice change29 These gures are lower than the estimated cost of

27 This is the average of two different estimates $12945432 and$17160000 The source of the rst gure is internal record of a supermarketchain of the type and size studied here The second gure comes from Supermar-ket Business [1993 p 52]

28 We also measured the menu costs in terms of controllable operating ex-penses (which are the portion of costs that the retailer has direct control over andtherefore are often the costs that the retailer is most focused on managing) andgross margins (which measure the supermarket revenues minus direct cost of theproducts it sells) We nd that the menu costs comprise 313 percent of controlla-ble operating expenses and 281 percent of gross margins at these chains on aver-age Finally if we measure the menu costs relative to the number of productscarried per store (about 25000) then we nd that the menu costs per productaverage $423 for Chains AndashD See Table IV and its footnotes for details

29 We can also try to express the menu cost gures relative to the numberof individual items sold by these chains each year (Note the difference betweennumber of products carried and number of items sold As an example a TartarControl Crest 8oz would be considered a product carried and 300 units of themsold per year would be considered number of items sold) Using $170 as the aver-age price of all the products sold we nd that the menu cost per item sold for thefour chains is in the range of $00103ndash$00129 for an average of $00119 (see TableIV second to last row) To see the relative magnitude of these gures note thataccording to Berkowitz Kerin and Rudelius [1986 p 319] the goal of the super-market chains of the type we study ldquo is to make 1 penny of prot on each dollarof salesrdquo Thus menu cost per item sold when adjusted for the average price

THE MAGNITUDE OF MENU COSTS 813

$200ndash$300 per price change reported by Slade [1996a] Thereare several possible reasons for this (1) our menu cost gures arebased on actual measurements of the resources that go into theprice change process whereas she estimates menu costs econo-metrically as model coefcients using a mix of store-level priceand aggregate cost data (2) we cover 25000 products that thesupermarkets carry rather than a single product category (3) ourmenu cost gures do not include all components of menu costsand (4) there could be differences in wage rates that may be im-portant given the signicance of the labor cost component inmenu costs

V2 The Effect of Menu Costs on the Price Change Activity of theSupermarkets

In this section we present evidence which suggests that thesemenu costs may be forming a barrier to price change activity Tobegin with consider the effect of the item pricing law on the pricechange activity of Chain E The data on the weekly frequency ofprice changes in each chain are displayed in the last two rows ofTable I According to these gures the average weekly frequencyof price changes in Chain E is only 1578 Thus on average ChainE changes the prices of only 631 percent of its products eachweek In contrast the average weekly frequency of price changesat Chains AndashD ranges from 3223 to 4316 for the four-chain aver-age of 3916 price changes weekly So Chains AndashD change priceson 1289 to 1726 percent of their products each week yielding afour-chain average of 1566 percent Thus Chain E which facesthe item pricing law changes prices only about one-third timesas frequently as do Chains AndashD30

Moreover within Chain E there are 400 products that areexempt from the item pricing law and thereby face lower menucosts We nd that there are an average of 83 weekly pricechanges for these products yielding 21 percent of these productschanging prices So within Chain E they change prices over threetimes as frequently for products with lower menu costs than for

roughly equals one-half of their target net prot per item which seemssubstantial

30 However note that our comparison of the two types of chains may not becompletely ceteris paribus because these stores are located in different states andtherefore there may be other chain-specic factors (in addition to item pricinglaws) that distinguish these stores We do not have any specic information onthese differences We do know however that the stores in these chains are similarin size and carry similar sets of products

QUARTERLY JOURNAL OF ECONOMICS814

the products with higher menu costs Note that this nding is onthe price change activity within the same chain offering almost anatural experiment on the impact of menu costs on the chainrsquospricing behavior Hence we provide evidence both across chainsas well as across products within a chain that as the costs ofchanging price go up the frequency of price changes goes downThus the menu costs we nd are signicant enough to affect thechainrsquos price change practice

We also have additional evidence from Chains A B and Dabout these menu costs being a barrier to certain price changesand it is summarized in Table V According to the Price Manage-ment Department of Chain A the chain experiences cost in-creases on 860 products in an average week to which it wouldlike to react with a price increase31 However on average 22 per-cent of these price increases are not implemented immediatelybecause the cost of changing prices for these products is too highto make it economically worthwhile Figures of the same magni-tude were reported by other chains For example Chain D experi-ences cost increases for 961 products in an average week Out ofthese the chain adjusts prices of only 633 products The re-maining 34 percent of the prices are left unadjusted because ofthe menu costs Similarly Chain B nds it economically ineffi-cient to adjust prices of 508 ie 30 percent of its products eachweek because of menu costs This provides additional evidencethat the menu costs incurred by these chains are preventing priceadjustments to some costs changes leading to price rigidities ofthe products involved32 Note that although we do not have simi-lar data for Chain E we would expect signicantly lower num-bers on this measure at that chain These gures also suggest anupper bound on the benet of complete price exibility under thecurrent pricing practice of weekly price adjustments Howeverif new technologies (eg ESL systems) and new pricing prac-tices (eg a decentralization of the price change decisions) are

31 Our data contain information only on the frequency of cost increasesAlthough it is more than likely that the supermarkets are experiencing cost de-creases as well our data set contained no information on such decreases

32 Menu costs may even be playing a role in the observed movement towardpricing strategies that rely on fewer price changes such as EDLP [Blattberg andNeslin 1989 Lattin and Ortmeyer 1991 Marketing News April 13 1992 p 8]According to Progressive Grocer [November 1992 p 50] ldquoA growing number ofoperators say they have switched from high-low pricing [to EDLP] They cite theinefciencies of making frequent price changes rdquo Similarly Hoch Dreze andPurk [1994 p 16] state that EDLP lowers operating costs by lowering ldquo in-store labor costs because of less frequent changeovers in special displaysrdquo

adopted allowing a fundamental change in the way the pricingmechanism is currently set the managers could consider morefrequent price change activity (eg multiple times each week) asmenu costs go down

In this paper we measure the menu costs at the chainsrsquo cur-rent level of price change activity It may be worthwhile to specu-late on the shape of the cost function relating menu costs to thefrequency of price changes by assessing how these costs wouldchange if the price change activity were to increase or to decreaseIt seems likely that many of the costs we report in this paper will(approximately) change linearly with additional price changeswithin the current range of price changes the chains are under-taking (plus or minus perhaps a thousand per week) For ex-ample the labor costs associated with changing a shelf price tagcosts of verifying price changes and the costs of mistakes oc-curring during this process all increase linearly with the fre-quency of price changes This is because most of the time-consuming steps involved in the price change process must berepeated each time an additional shelf price tag is changed (seeTable II) Further we were unable to nd many tasks that gener-ated signicant returns to scale It is unclear what cost savingsare available if the price change activity drops substantially be-

low the levels it is at now Clearly if price changes were nearzero or done less frequently than weekly (say monthly) therecould be major differences in these costs

What is less clear is how these costs would change at moreextreme levels of price change activity With less frequent pricechanges the menu costs could probably be reduced signicantlyalthough the cost of deciding what prices to set initially and thecost of putting the initial shelf price tags would still remain as alower bound of the menu cost However for achieving more priceexibility by changing prices more frequently (ie multiple timeseach week) substantial changes must be undertaken At presentthe supermarket chains are set up to make the majority of theirprice changes on a weekly basis with the appropriate systems inplace to make this process most efcient For example in orderto save costs and to have higher quality price tags (eg withcolor more details greater clarity glossy etc) the chains oftensend new price tag requests to a printing shop which takes threedays to print and deliver the labels to each store Then giventhe large number of price changes taking place and the goals ofminimizing customer disruptions and labor costs (such as over-time pay) and coordinating with advertised price promotions theprices are changed in the store over a two-to-three-day period (seeTable VI) The combination of these schedule and built-in lags isacceptable under the current practice of changing prices weeklybut would have to be adjusted dramatically to allow for signifi-cantly more frequent price changes on a regular basis

Perhaps even more imposing are the costs of changing themanagerial costs associated with the current weekly system ofprice changes The process of pricing at this organizational levelis not a self-contained activity taking place in isolation from otheroperations of the supermarket management Rather it is a partof a larger system of business decisions and operations The cur-rent process of operations (such as data collection and theiranalysis management meetings coordination of the decisionsacross functional areas etc) is set up to function on a weeklybasis33 Further these management accounting and logisticssystems are currently built around a tremendous amount of in-

33 For example the data are analyzed and presented to managers on Mon-day and Tuesday with meetings set for Thursday and Friday to make pricingdecisions for the next week in coordination with all other business functions ofthe chain

formation to be analyzed for thousands of products34 Accommo-dating more frequent price changes on a regular basis wouldrequire a radical adjustment of many managerial substructuresand units at both corporate and store levels which could involvecostly investment in restructuring and retraining the existing la-bor force as well as in new physical and human capital Thus thecost function relating the menu costs to the frequency of pricechanges would be approximately linear from zero to roughlyabout 5000 price changes per week With higher frequency ofprice changes under the current weekly pricing practice themenu costs are likely to increase dramatically perhaps by asmuch as ten-to-twenty times according to the ESL executives35

34 For example under the current system a chainwide category manageroperating at the corporate headquarters needs to study and assess numerouspieces of detailed information such as competitorsrsquo price and sale information fromthe last week the past weekrsquos sales at the own chain manufacturersupplier pro-motions wholesale price reductions coop allowances new product offerings shelfspace decisions coordination with newspaper advertising logistics at the ware-houses as well as at each store store differences in terms of customer characteris-tics and competitive environments productshelf selection and layout etc

35 If the supermarket chains indeed restructure the entire price change pro-cess and begin to change prices much more frequently (say two-to-three times aweek) on a regular basis then the shape of this cost function could change in anunpredictable way

V3 Relating Our Findings to the Existing Theoretical Models ofMenu Costs

In order to assess the magnitude of these menu cost guresin the context of the existing theoretical menu cost literatureconsider the following calculation experiments done within theframework of two theoretical menu cost models Blanchard andKiyotaki [1987] study a general equilibrium menu cost modelwith monopolistic competition and with unit elasticity of aggre-gate demand with respect to real money balances According totheir calculations menu costs of the magnitude of 008 percent ofrevenues which they consider ldquovery smallrdquo may be sufcient toprevent adjustment of prices Ball and Romer [1990] conductsimilar calculations in the framework of a model with imperfectcompetition and menu costs They nd that for plausible markupand labor elasticity parameter values menu costs needed to pre-vent price adjustment are 070 percent of revenues which as theysuggest are nonnegligible For smaller menu costs eg 004 per-cent of the revenue which Ball and Romer consider ldquotrivialrdquo im-plausibly large values of markup and labor elasticity parametersare needed to prevent price adjustment to monetary shocks

According to the gures in Table IV the reported menu costto revenues ratio for Chains AndashD averages 070 percent rangingfrom 061 percent to 076 percent These are signicantly largerthan the ldquotrivialrdquo 004 or 008 percent gures mentioned abovesuggesting that the menu cost gures we nd here are nontrivialFurther under the model and parameter values considered byBlanchard and Kiyotaki [1987] the menu cost gures we nd arehigher than the theoretical minimum needed to form a barrier toprice adjustments Under the model and parameter values con-sidered by Ball and Romer [1990] the reported menu costreve-nue ratio for all but one chain reaches or crosses the theoreticalthreshold of 070 needed to form a barrier to price adjustmentsThe existence of numerous unmeasured menu cost componentsdiscussed in subsection III5 also raises the possibility that theactual menu costs incurred by these chains are signicantlyhigher than that threshold This suggests that the menu costs wereport may be large enough to form a barrier to nominal priceadjustments when interpreted in the context of these models

An issue of interest in this literature is time-dependent ver-sus state-dependent pricing rules (see for example Caplin andLeahy [1991]) The evidence from our data set on the timing of

THE MAGNITUDE OF MENU COSTS 819

price changes suggests that the price change decisions in thesesupermarkets have a strong time-dependent price-setting ele-ment36 For example according to Table VI the prices in Chain Aare changed weekly according to the following schedule the pricechanges of general merchandise that is advertised is done Satur-day nights grocery and produce prices are changed Sundaynights the rest of the general merchandise prices are changed onMonday nights and the prices of advertised grocery items arechanged on Tuesday nights Thus as the gures in Table VI indi-cate over 96 percent of the price changes are done during Sundayand Monday nights However this does not imply that state-dependent pricing rules are unimportant Even if price changesacross product categories follow a prescheduled weekly time ta-ble the prices of which products to change is likely to be a state-dependent decision For example it could depend on changes insupply and demand conditions such as competitorsrsquo price changedecisions Indeed Levy Dutta and Bergen [1996] use retailstore-level orange juice price and cost data to demonstrate thatthe extent of price response to cost shocks that is the extent ofprice rigidity may depend on the nature of supply shocks37

We do not want to overstate the usefulness of our data fordirectly addressing the issue of monetary nonneutrality On onehand authors such as Caplin and Spulber [1987] have demon-strated that under certain conditions individual price rigiditymay not be sufcient for aggregate price rigidity but unfortu-nately our data do not speak directly to this issue38 On the otherhand authors such as Akerlof and Yellen [1985] Mankiw [1985]Parkin [1986] and Caplin and Leahy [1997] have shown that even

36 Danziger [1983] Caballero [1989] and Ball and Mankiw [1994] suggestthat time-dependent price adjustment of the type documented here can be optimalif the cost of gathering information about the state exceeds the cost of making theprice adjustment itself

37 We also considered the possibility of convexities in the cost of changingprices Our data do not suggest many convexities since the labor time spent inthe price tag change process the cost of printing and delivering price tags andin-store supervision time do not change with the size of a price change The onlymeasurable component of menu costs that could be convex is the cost of mistakesmade the larger the price change the higher the probability of a customer notic-ing the mistake and the larger the amount required to be refunded as compensa-tion Among the unmeasured components of menu cost the cost of corporatemanagerial time may increase with the size of a price change because larger pricechanges may require more serious consideration

38 Also see Balke and Wynne [1996] and Bryan and Cecchetti [1996] Sincewe do not have measures of how menu costs change over time our data also havelittle to say about time variation in menu costs or about the relationship betweenmenu costs and ination which during the period of the data collection (1991ndash1992) averaged about 3 percent annually

QUARTERLY JOURNAL OF ECONOMICS820

small menu costs can be relevant since they may be sufcient togenerate substantial aggregate nominal rigidity and thus largebusiness cycles Therefore as Blinder [1994] Kashyap [1995]and Slade [1996a] emphasize it is important to search for directevidence that such costs are indeed present at the micro level Bydirectly identifying documenting and measuring the magnitudeof menu costs at the store level we are taking an important stepin that direction

VI CONCLUSION AND FUTURE RESEARCH

Our main contribution is that we provide direct microeco-nomic evidence on the actual magnitude of menu costs for fourlarge U S retail supermarket chains The annual menu costs perstore at these chains average $105887 comprising 070 percentof revenues 352 percent of net prot margins and $052 perprice change on average

Further we provide evidence which suggests that thesemenu costs may be forming a barrier to price changes Specifi-cally we show that (1) supermarket chains not subject to itempricing law change prices two and a half times more frequentlythan the chain that is subject to the law (2) within the chain thatis subject to the item pricing law they change prices over threetimes as frequently for products that are exempt from this lawthan for the products which are subject to this law and (3) wend that these chains do not adjust prices of up to one-third ofthe products for which they face cost increases because of menucost considerations

When we relate these ndings to the existing theoreticalmodels of menu costs we conclude that the magnitude of menucosts we nd is large enough to be capable of having macroeco-nomic signicance Specically when considered in the context ofthe theoretical menu cost models of Blanchard and Kiyotaki[1987] and Ball and Romer [1990] we nd that the menu costgures we report are ldquonontrivialrdquo and their relative magnitudescross the minimum theoretical threshold needed to form a barrierto price adjustments

Despite the high relative magnitude of the marginal cost ofchanging price that we found the data still indicate frequentweekly price changes This is because of the high marginal bene-t of changing price which is due to the erce competition foundin the retail supermarket industry That marginal benets may

THE MAGNITUDE OF MENU COSTS 821

outweigh the marginal costs of changing prices in this industryhowever does not rule out the possibility that menu costs of themagnitude we nd here can create substantial nominal rigidityin other industries or markets In less competitive industries andmarkets menu costs of the type and magnitude we documenthere are likely to have a bigger impact on the frequency of priceadjustment and consequently on the degree of price rigidity

At a minimum the direct dollar measures of menu costs wereport here can be used as a starting point for future research onmeasuring their magnitude in other industries and establish-ments We anticipate that these menu costs will be similar inother markets which rely on posted prices (such as drugstoresdepartment stores etc) because the steps involved in the pricechange process are likely to be similar What may differ are thefrequency of price changes and the labor wage rates at thesestores For example since supermarket chains change thousandsof prices each week the total annual menu costs incurred bythese chains per store are likely to be high in comparison to otherretail formats such as chain drugstores or department storesThere are however a variety of industries for which the stepsinvolved in changing prices would be signicantly different fromthose reported in our study For example business-to-businesssales which often rely on a sales force will require changes in thelist price sheets changes in the instructions to the sales forcewhich may include education and discussion with the salespeoplein the company and so forth These business-to-business pricesalso often have more complex pricing schemes including quantitydiscounts bundling and individually negotiated prices As an-other example the composition of the cost of changing the news-stand prices of magazines [Cecchetti 1986] or the prices ofproducts sold through catalogs [Kashyap 1995] are different frommany of the menu cost components we discuss here Further thending that a centralization of pricing decisions makes the store-level managerial component of menu cost relatively small sug-gests that the managerial menu costs likely are highest insettings where price change decisions are decentralized Thus fu-ture empirical work should look at menu cost and its compositionin a variety of other industries markets and products with bothcentralized as well as decentralized price change decisions in or-der to see whether the magnitude of these costs can be general-ized and benchmarks can be established Further there aretechnological changes taking place in this and other industries

that promise to alter the structure of menu costs which deserveattention At the theoretical level our ndings suggest that it maybe worthwhile to explore models which incorporate the idea ofitem pricing laws as an additional component of menu costs

sures include only the components we could accurately measurein dollar terms which are discussed in subsections III1ndashIII4

IV ITEM PRICING LAWS AND MENU COSTS

In this section we provide evidence on the menu costs for anadditional chain (Chain E) which unlike the other four chainsoperates in a state with an item pricing law The most importantaspect of item pricing laws is that they require a price tag on eachindividual item sold not just on the shelf which is what the otherfour chains in our sample do For example the item pricing lawin Connecticut requires that the grocers ldquoshall mark or cause tobe marked each consumer commodity which bears a UniversalProduct Code with its retail pricerdquo 22 From a menu cost perspec-tive the requirement of posting prices on every item (in additionto the shelf price tag) introduces additional costs in the processof changing prices

Although most of the steps involved in changing prices arethe same for both types of chains stores that are subject to itempricing laws have to undertake additional steps to obey this law23

The labor cost component of menu costs in Chain E totals $75127a year of which $49710 is the cost of the labor time spent onchanging the prices of individual items $3234 is the cost of thelabor time spent on shelf tag replacements and $22183 is thecost of the labor time spent on sign changes (see Table III)24 Anadditional $44168 is spent annually putting prices on new itemsas they are brought to the shelves Although we do not includethis last gure in our menu cost measures because we do not haveinformation on how much of it is due to price change activity andhow much due to just pricingmdashthese costs are clearly a directconsequence of the item pricing law The printing and deliverycost of price tags and price signs are $7644 and the mistake

22 Public Act No 75ndash391 An Act Concerning Pricing of Consumer Merchan-dise [Public Acts of the State of Connecticut 1975 Vol 1 p 390]

23 These steps which are in addition to the regular steps undertaken toreplace price tags on the shelves include (1) obtaining item price tags (2) settingup workstations (3) locating the product (4) removing an item from the shelf (5)removing old price tag (6) setting marking gun (7) applying new price tag and(8) returning the item back to the shelf

24 Since we do not have a measure of the cost of labor time spent on signchanges and the cost of in-store managerial supervision time for this chain weuse the average of the chains that report them (A and D) Note also that thehourly wage rate of $907 paid by Chain E is lower than the hourly wage of about$1400ndash$2000 paid by Chains AndashD

QUARTERLY JOURNAL OF ECONOMICS810

25 Further note that the chains with smaller menu costs are likely tochange their prices more frequently which suggests that the gures of the totalannual menu costs understate the differences between Chain E and the otherchains Indeed despite the large difference in the menu cost per price change thetotal annual menu costs per store for Chain E ($109036) are more comparable tothose of Chains AndashD ($105887)

26 In calculations that follow we use industry averages because (1) thechains did not share this proprietary information with us and (2) we were re-quired to keep the identity of these chains condential as some of these numbersare detailed enough to enable some readers to identify the chains under study

costs are $20799 These gures along with the amount of $5466for the cost of in-store managerial supervision time yield totalannual menu costs of $109036 per store

Although the magnitude of the total annual menu costs seemsimilar to the other four chains note that the average weeklyfrequency of price changes in Chain E is only 1578 which is only403 ( 5 15783916) percent of the price changes made by theother four chains Thus the average menu cost per price changefor Chain E is $133 (see Table IV last row) In contrast the corre-sponding gures for Chains AndashD average $052 Hence the menucosts per price change incurred by the supermarket chain facingitem pricing laws are more than two and a half times the amountincurred by chains that are not subject to this law25 Overallthese ndings suggest that legal restrictions of the type of itempricing laws can have a signicant impact on the menu costs in-curred by sellers

V SIGNIFICANCE OF THE MENU COSTS

The next natural question to ask is how important are thesecosts To address this question we (1) provide several relativemeasures of the menu costs (2) discuss the effect of the menucosts on supermarketsrsquo price change activity and (3) discuss mac-roeconomic implications by relating our ndings to the existingtheoretical models of menu costs In each case we provide addi-tional evidence to help assess the importance of these menu costs

V1 Relative Measures of the Menu Costs

In order to assess the relative magnitude of the menu costsreported in Section IV we now present the menu cost gures rela-tive to the average store-level revenues and net prot margins26

In addition we present the menu cost gures per price changeThe annual average revenues of a large U S supermarket

chain of the type and size included in our sample is $15052716

Net prot margin which measures the revenues minus allcosts is approximately 1ndash3 percent of revenues for these chains[Montgomery 1994] so we use 2 percent as a working averageThe reason for the low prot rate in this industry is the intensecompetition [Calatone et al 1989] especially at the regional level[Chevalier 1995] which has been increasing since the early 1990s[Progressive Grocer November 1992 p 50] It follows that theaverage store protability for these chains equals $301054 peryear Therefore the ratio of total menu cost to net margin forChains AndashD ranges between 304ndash379 percent for an average of352 percent Thus the menu costs we report in this study repre-sent a signicant share of supermarketsrsquo prots

Another way to look at the menu cost gures we report is toexpress them relative to the frequency of price changes In thelast row of Table IV we present the menu cost gures per pricechange for each chain As the table indicates the cost of changinga price in Chains AndashD ranges between $046ndash$068 for an averageof $052 For Chain E the gure is substantially larger $133 perprice change29 These gures are lower than the estimated cost of

27 This is the average of two different estimates $12945432 and$17160000 The source of the rst gure is internal record of a supermarketchain of the type and size studied here The second gure comes from Supermar-ket Business [1993 p 52]

28 We also measured the menu costs in terms of controllable operating ex-penses (which are the portion of costs that the retailer has direct control over andtherefore are often the costs that the retailer is most focused on managing) andgross margins (which measure the supermarket revenues minus direct cost of theproducts it sells) We nd that the menu costs comprise 313 percent of controlla-ble operating expenses and 281 percent of gross margins at these chains on aver-age Finally if we measure the menu costs relative to the number of productscarried per store (about 25000) then we nd that the menu costs per productaverage $423 for Chains AndashD See Table IV and its footnotes for details

29 We can also try to express the menu cost gures relative to the numberof individual items sold by these chains each year (Note the difference betweennumber of products carried and number of items sold As an example a TartarControl Crest 8oz would be considered a product carried and 300 units of themsold per year would be considered number of items sold) Using $170 as the aver-age price of all the products sold we nd that the menu cost per item sold for thefour chains is in the range of $00103ndash$00129 for an average of $00119 (see TableIV second to last row) To see the relative magnitude of these gures note thataccording to Berkowitz Kerin and Rudelius [1986 p 319] the goal of the super-market chains of the type we study ldquo is to make 1 penny of prot on each dollarof salesrdquo Thus menu cost per item sold when adjusted for the average price

$200ndash$300 per price change reported by Slade [1996a] Thereare several possible reasons for this (1) our menu cost gures arebased on actual measurements of the resources that go into theprice change process whereas she estimates menu costs econo-metrically as model coefcients using a mix of store-level priceand aggregate cost data (2) we cover 25000 products that thesupermarkets carry rather than a single product category (3) ourmenu cost gures do not include all components of menu costsand (4) there could be differences in wage rates that may be im-portant given the signicance of the labor cost component inmenu costs

V2 The Effect of Menu Costs on the Price Change Activity of theSupermarkets

In this section we present evidence which suggests that thesemenu costs may be forming a barrier to price change activity Tobegin with consider the effect of the item pricing law on the pricechange activity of Chain E The data on the weekly frequency ofprice changes in each chain are displayed in the last two rows ofTable I According to these gures the average weekly frequencyof price changes in Chain E is only 1578 Thus on average ChainE changes the prices of only 631 percent of its products eachweek In contrast the average weekly frequency of price changesat Chains AndashD ranges from 3223 to 4316 for the four-chain aver-age of 3916 price changes weekly So Chains AndashD change priceson 1289 to 1726 percent of their products each week yielding afour-chain average of 1566 percent Thus Chain E which facesthe item pricing law changes prices only about one-third timesas frequently as do Chains AndashD30

Moreover within Chain E there are 400 products that areexempt from the item pricing law and thereby face lower menucosts We nd that there are an average of 83 weekly pricechanges for these products yielding 21 percent of these productschanging prices So within Chain E they change prices over threetimes as frequently for products with lower menu costs than for

roughly equals one-half of their target net prot per item which seemssubstantial

30 However note that our comparison of the two types of chains may not becompletely ceteris paribus because these stores are located in different states andtherefore there may be other chain-specic factors (in addition to item pricinglaws) that distinguish these stores We do not have any specic information onthese differences We do know however that the stores in these chains are similarin size and carry similar sets of products

QUARTERLY JOURNAL OF ECONOMICS814

the products with higher menu costs Note that this nding is onthe price change activity within the same chain offering almost anatural experiment on the impact of menu costs on the chainrsquospricing behavior Hence we provide evidence both across chainsas well as across products within a chain that as the costs ofchanging price go up the frequency of price changes goes downThus the menu costs we nd are signicant enough to affect thechainrsquos price change practice

We also have additional evidence from Chains A B and Dabout these menu costs being a barrier to certain price changesand it is summarized in Table V According to the Price Manage-ment Department of Chain A the chain experiences cost in-creases on 860 products in an average week to which it wouldlike to react with a price increase31 However on average 22 per-cent of these price increases are not implemented immediatelybecause the cost of changing prices for these products is too highto make it economically worthwhile Figures of the same magni-tude were reported by other chains For example Chain D experi-ences cost increases for 961 products in an average week Out ofthese the chain adjusts prices of only 633 products The re-maining 34 percent of the prices are left unadjusted because ofthe menu costs Similarly Chain B nds it economically ineffi-cient to adjust prices of 508 ie 30 percent of its products eachweek because of menu costs This provides additional evidencethat the menu costs incurred by these chains are preventing priceadjustments to some costs changes leading to price rigidities ofthe products involved32 Note that although we do not have simi-lar data for Chain E we would expect signicantly lower num-bers on this measure at that chain These gures also suggest anupper bound on the benet of complete price exibility under thecurrent pricing practice of weekly price adjustments Howeverif new technologies (eg ESL systems) and new pricing prac-tices (eg a decentralization of the price change decisions) are

31 Our data contain information only on the frequency of cost increasesAlthough it is more than likely that the supermarkets are experiencing cost de-creases as well our data set contained no information on such decreases

32 Menu costs may even be playing a role in the observed movement towardpricing strategies that rely on fewer price changes such as EDLP [Blattberg andNeslin 1989 Lattin and Ortmeyer 1991 Marketing News April 13 1992 p 8]According to Progressive Grocer [November 1992 p 50] ldquoA growing number ofoperators say they have switched from high-low pricing [to EDLP] They cite theinefciencies of making frequent price changes rdquo Similarly Hoch Dreze andPurk [1994 p 16] state that EDLP lowers operating costs by lowering ldquo in-store labor costs because of less frequent changeovers in special displaysrdquo

adopted allowing a fundamental change in the way the pricingmechanism is currently set the managers could consider morefrequent price change activity (eg multiple times each week) asmenu costs go down

In this paper we measure the menu costs at the chainsrsquo cur-rent level of price change activity It may be worthwhile to specu-late on the shape of the cost function relating menu costs to thefrequency of price changes by assessing how these costs wouldchange if the price change activity were to increase or to decreaseIt seems likely that many of the costs we report in this paper will(approximately) change linearly with additional price changeswithin the current range of price changes the chains are under-taking (plus or minus perhaps a thousand per week) For ex-ample the labor costs associated with changing a shelf price tagcosts of verifying price changes and the costs of mistakes oc-curring during this process all increase linearly with the fre-quency of price changes This is because most of the time-consuming steps involved in the price change process must berepeated each time an additional shelf price tag is changed (seeTable II) Further we were unable to nd many tasks that gener-ated signicant returns to scale It is unclear what cost savingsare available if the price change activity drops substantially be-

QUARTERLY JOURNAL OF ECONOMICS816

low the levels it is at now Clearly if price changes were nearzero or done less frequently than weekly (say monthly) therecould be major differences in these costs

What is less clear is how these costs would change at moreextreme levels of price change activity With less frequent pricechanges the menu costs could probably be reduced signicantlyalthough the cost of deciding what prices to set initially and thecost of putting the initial shelf price tags would still remain as alower bound of the menu cost However for achieving more priceexibility by changing prices more frequently (ie multiple timeseach week) substantial changes must be undertaken At presentthe supermarket chains are set up to make the majority of theirprice changes on a weekly basis with the appropriate systems inplace to make this process most efcient For example in orderto save costs and to have higher quality price tags (eg withcolor more details greater clarity glossy etc) the chains oftensend new price tag requests to a printing shop which takes threedays to print and deliver the labels to each store Then giventhe large number of price changes taking place and the goals ofminimizing customer disruptions and labor costs (such as over-time pay) and coordinating with advertised price promotions theprices are changed in the store over a two-to-three-day period (seeTable VI) The combination of these schedule and built-in lags isacceptable under the current practice of changing prices weeklybut would have to be adjusted dramatically to allow for signifi-cantly more frequent price changes on a regular basis

Perhaps even more imposing are the costs of changing themanagerial costs associated with the current weekly system ofprice changes The process of pricing at this organizational levelis not a self-contained activity taking place in isolation from otheroperations of the supermarket management Rather it is a partof a larger system of business decisions and operations The cur-rent process of operations (such as data collection and theiranalysis management meetings coordination of the decisionsacross functional areas etc) is set up to function on a weeklybasis33 Further these management accounting and logisticssystems are currently built around a tremendous amount of in-

35 If the supermarket chains indeed restructure the entire price change pro-cess and begin to change prices much more frequently (say two-to-three times aweek) on a regular basis then the shape of this cost function could change in anunpredictable way

V3 Relating Our Findings to the Existing Theoretical Models ofMenu Costs

In order to assess the magnitude of these menu cost guresin the context of the existing theoretical menu cost literatureconsider the following calculation experiments done within theframework of two theoretical menu cost models Blanchard andKiyotaki [1987] study a general equilibrium menu cost modelwith monopolistic competition and with unit elasticity of aggre-gate demand with respect to real money balances According totheir calculations menu costs of the magnitude of 008 percent ofrevenues which they consider ldquovery smallrdquo may be sufcient toprevent adjustment of prices Ball and Romer [1990] conductsimilar calculations in the framework of a model with imperfectcompetition and menu costs They nd that for plausible markupand labor elasticity parameter values menu costs needed to pre-vent price adjustment are 070 percent of revenues which as theysuggest are nonnegligible For smaller menu costs eg 004 per-cent of the revenue which Ball and Romer consider ldquotrivialrdquo im-plausibly large values of markup and labor elasticity parametersare needed to prevent price adjustment to monetary shocks

According to the gures in Table IV the reported menu costto revenues ratio for Chains AndashD averages 070 percent rangingfrom 061 percent to 076 percent These are signicantly largerthan the ldquotrivialrdquo 004 or 008 percent gures mentioned abovesuggesting that the menu cost gures we nd here are nontrivialFurther under the model and parameter values considered byBlanchard and Kiyotaki [1987] the menu cost gures we nd arehigher than the theoretical minimum needed to form a barrier toprice adjustments Under the model and parameter values con-sidered by Ball and Romer [1990] the reported menu costreve-nue ratio for all but one chain reaches or crosses the theoreticalthreshold of 070 needed to form a barrier to price adjustmentsThe existence of numerous unmeasured menu cost componentsdiscussed in subsection III5 also raises the possibility that theactual menu costs incurred by these chains are signicantlyhigher than that threshold This suggests that the menu costs wereport may be large enough to form a barrier to nominal priceadjustments when interpreted in the context of these models

An issue of interest in this literature is time-dependent ver-sus state-dependent pricing rules (see for example Caplin andLeahy [1991]) The evidence from our data set on the timing of

THE MAGNITUDE OF MENU COSTS 819

price changes suggests that the price change decisions in thesesupermarkets have a strong time-dependent price-setting ele-ment36 For example according to Table VI the prices in Chain Aare changed weekly according to the following schedule the pricechanges of general merchandise that is advertised is done Satur-day nights grocery and produce prices are changed Sundaynights the rest of the general merchandise prices are changed onMonday nights and the prices of advertised grocery items arechanged on Tuesday nights Thus as the gures in Table VI indi-cate over 96 percent of the price changes are done during Sundayand Monday nights However this does not imply that state-dependent pricing rules are unimportant Even if price changesacross product categories follow a prescheduled weekly time ta-ble the prices of which products to change is likely to be a state-dependent decision For example it could depend on changes insupply and demand conditions such as competitorsrsquo price changedecisions Indeed Levy Dutta and Bergen [1996] use retailstore-level orange juice price and cost data to demonstrate thatthe extent of price response to cost shocks that is the extent ofprice rigidity may depend on the nature of supply shocks37

We do not want to overstate the usefulness of our data fordirectly addressing the issue of monetary nonneutrality On onehand authors such as Caplin and Spulber [1987] have demon-strated that under certain conditions individual price rigiditymay not be sufcient for aggregate price rigidity but unfortu-nately our data do not speak directly to this issue38 On the otherhand authors such as Akerlof and Yellen [1985] Mankiw [1985]Parkin [1986] and Caplin and Leahy [1997] have shown that even

36 Danziger [1983] Caballero [1989] and Ball and Mankiw [1994] suggestthat time-dependent price adjustment of the type documented here can be optimalif the cost of gathering information about the state exceeds the cost of making theprice adjustment itself

37 We also considered the possibility of convexities in the cost of changingprices Our data do not suggest many convexities since the labor time spent inthe price tag change process the cost of printing and delivering price tags andin-store supervision time do not change with the size of a price change The onlymeasurable component of menu costs that could be convex is the cost of mistakesmade the larger the price change the higher the probability of a customer notic-ing the mistake and the larger the amount required to be refunded as compensa-tion Among the unmeasured components of menu cost the cost of corporatemanagerial time may increase with the size of a price change because larger pricechanges may require more serious consideration

38 Also see Balke and Wynne [1996] and Bryan and Cecchetti [1996] Sincewe do not have measures of how menu costs change over time our data also havelittle to say about time variation in menu costs or about the relationship betweenmenu costs and ination which during the period of the data collection (1991ndash1992) averaged about 3 percent annually

QUARTERLY JOURNAL OF ECONOMICS820

small menu costs can be relevant since they may be sufcient togenerate substantial aggregate nominal rigidity and thus largebusiness cycles Therefore as Blinder [1994] Kashyap [1995]and Slade [1996a] emphasize it is important to search for directevidence that such costs are indeed present at the micro level Bydirectly identifying documenting and measuring the magnitudeof menu costs at the store level we are taking an important stepin that direction

VI CONCLUSION AND FUTURE RESEARCH

Our main contribution is that we provide direct microeco-nomic evidence on the actual magnitude of menu costs for fourlarge U S retail supermarket chains The annual menu costs perstore at these chains average $105887 comprising 070 percentof revenues 352 percent of net prot margins and $052 perprice change on average

Further we provide evidence which suggests that thesemenu costs may be forming a barrier to price changes Specifi-cally we show that (1) supermarket chains not subject to itempricing law change prices two and a half times more frequentlythan the chain that is subject to the law (2) within the chain thatis subject to the item pricing law they change prices over threetimes as frequently for products that are exempt from this lawthan for the products which are subject to this law and (3) wend that these chains do not adjust prices of up to one-third ofthe products for which they face cost increases because of menucost considerations

When we relate these ndings to the existing theoreticalmodels of menu costs we conclude that the magnitude of menucosts we nd is large enough to be capable of having macroeco-nomic signicance Specically when considered in the context ofthe theoretical menu cost models of Blanchard and Kiyotaki[1987] and Ball and Romer [1990] we nd that the menu costgures we report are ldquonontrivialrdquo and their relative magnitudescross the minimum theoretical threshold needed to form a barrierto price adjustments

Despite the high relative magnitude of the marginal cost ofchanging price that we found the data still indicate frequentweekly price changes This is because of the high marginal bene-t of changing price which is due to the erce competition foundin the retail supermarket industry That marginal benets may

THE MAGNITUDE OF MENU COSTS 821

outweigh the marginal costs of changing prices in this industryhowever does not rule out the possibility that menu costs of themagnitude we nd here can create substantial nominal rigidityin other industries or markets In less competitive industries andmarkets menu costs of the type and magnitude we documenthere are likely to have a bigger impact on the frequency of priceadjustment and consequently on the degree of price rigidity

At a minimum the direct dollar measures of menu costs wereport here can be used as a starting point for future research onmeasuring their magnitude in other industries and establish-ments We anticipate that these menu costs will be similar inother markets which rely on posted prices (such as drugstoresdepartment stores etc) because the steps involved in the pricechange process are likely to be similar What may differ are thefrequency of price changes and the labor wage rates at thesestores For example since supermarket chains change thousandsof prices each week the total annual menu costs incurred bythese chains per store are likely to be high in comparison to otherretail formats such as chain drugstores or department storesThere are however a variety of industries for which the stepsinvolved in changing prices would be signicantly different fromthose reported in our study For example business-to-businesssales which often rely on a sales force will require changes in thelist price sheets changes in the instructions to the sales forcewhich may include education and discussion with the salespeoplein the company and so forth These business-to-business pricesalso often have more complex pricing schemes including quantitydiscounts bundling and individually negotiated prices As an-other example the composition of the cost of changing the news-stand prices of magazines [Cecchetti 1986] or the prices ofproducts sold through catalogs [Kashyap 1995] are different frommany of the menu cost components we discuss here Further thending that a centralization of pricing decisions makes the store-level managerial component of menu cost relatively small sug-gests that the managerial menu costs likely are highest insettings where price change decisions are decentralized Thus fu-ture empirical work should look at menu cost and its compositionin a variety of other industries markets and products with bothcentralized as well as decentralized price change decisions in or-der to see whether the magnitude of these costs can be general-ized and benchmarks can be established Further there aretechnological changes taking place in this and other industries

that promise to alter the structure of menu costs which deserveattention At the theoretical level our ndings suggest that it maybe worthwhile to explore models which incorporate the idea ofitem pricing laws as an additional component of menu costs

25 Further note that the chains with smaller menu costs are likely tochange their prices more frequently which suggests that the gures of the totalannual menu costs understate the differences between Chain E and the otherchains Indeed despite the large difference in the menu cost per price change thetotal annual menu costs per store for Chain E ($109036) are more comparable tothose of Chains AndashD ($105887)

26 In calculations that follow we use industry averages because (1) thechains did not share this proprietary information with us and (2) we were re-quired to keep the identity of these chains condential as some of these numbersare detailed enough to enable some readers to identify the chains under study

costs are $20799 These gures along with the amount of $5466for the cost of in-store managerial supervision time yield totalannual menu costs of $109036 per store

Although the magnitude of the total annual menu costs seemsimilar to the other four chains note that the average weeklyfrequency of price changes in Chain E is only 1578 which is only403 ( 5 15783916) percent of the price changes made by theother four chains Thus the average menu cost per price changefor Chain E is $133 (see Table IV last row) In contrast the corre-sponding gures for Chains AndashD average $052 Hence the menucosts per price change incurred by the supermarket chain facingitem pricing laws are more than two and a half times the amountincurred by chains that are not subject to this law25 Overallthese ndings suggest that legal restrictions of the type of itempricing laws can have a signicant impact on the menu costs in-curred by sellers

V SIGNIFICANCE OF THE MENU COSTS

The next natural question to ask is how important are thesecosts To address this question we (1) provide several relativemeasures of the menu costs (2) discuss the effect of the menucosts on supermarketsrsquo price change activity and (3) discuss mac-roeconomic implications by relating our ndings to the existingtheoretical models of menu costs In each case we provide addi-tional evidence to help assess the importance of these menu costs

V1 Relative Measures of the Menu Costs

In order to assess the relative magnitude of the menu costsreported in Section IV we now present the menu cost gures rela-tive to the average store-level revenues and net prot margins26

In addition we present the menu cost gures per price changeThe annual average revenues of a large U S supermarket

chain of the type and size included in our sample is $15052716

per store27 According to the second row of Table IV the ratio ofmenu costs to revenues for Chains AndashD ranges between 061ndash076percent averaging 070 percent28 We relate the size of thesegures to the existing theoretical menu cost models in sub-section V3

Net prot margin which measures the revenues minus allcosts is approximately 1ndash3 percent of revenues for these chains[Montgomery 1994] so we use 2 percent as a working averageThe reason for the low prot rate in this industry is the intensecompetition [Calatone et al 1989] especially at the regional level[Chevalier 1995] which has been increasing since the early 1990s[Progressive Grocer November 1992 p 50] It follows that theaverage store protability for these chains equals $301054 peryear Therefore the ratio of total menu cost to net margin forChains AndashD ranges between 304ndash379 percent for an average of352 percent Thus the menu costs we report in this study repre-sent a signicant share of supermarketsrsquo prots

Another way to look at the menu cost gures we report is toexpress them relative to the frequency of price changes In thelast row of Table IV we present the menu cost gures per pricechange for each chain As the table indicates the cost of changinga price in Chains AndashD ranges between $046ndash$068 for an averageof $052 For Chain E the gure is substantially larger $133 perprice change29 These gures are lower than the estimated cost of

27 This is the average of two different estimates $12945432 and$17160000 The source of the rst gure is internal record of a supermarketchain of the type and size studied here The second gure comes from Supermar-ket Business [1993 p 52]

28 We also measured the menu costs in terms of controllable operating ex-penses (which are the portion of costs that the retailer has direct control over andtherefore are often the costs that the retailer is most focused on managing) andgross margins (which measure the supermarket revenues minus direct cost of theproducts it sells) We nd that the menu costs comprise 313 percent of controlla-ble operating expenses and 281 percent of gross margins at these chains on aver-age Finally if we measure the menu costs relative to the number of productscarried per store (about 25000) then we nd that the menu costs per productaverage $423 for Chains AndashD See Table IV and its footnotes for details

29 We can also try to express the menu cost gures relative to the numberof individual items sold by these chains each year (Note the difference betweennumber of products carried and number of items sold As an example a TartarControl Crest 8oz would be considered a product carried and 300 units of themsold per year would be considered number of items sold) Using $170 as the aver-age price of all the products sold we nd that the menu cost per item sold for thefour chains is in the range of $00103ndash$00129 for an average of $00119 (see TableIV second to last row) To see the relative magnitude of these gures note thataccording to Berkowitz Kerin and Rudelius [1986 p 319] the goal of the super-market chains of the type we study ldquo is to make 1 penny of prot on each dollarof salesrdquo Thus menu cost per item sold when adjusted for the average price

THE MAGNITUDE OF MENU COSTS 813

$200ndash$300 per price change reported by Slade [1996a] Thereare several possible reasons for this (1) our menu cost gures arebased on actual measurements of the resources that go into theprice change process whereas she estimates menu costs econo-metrically as model coefcients using a mix of store-level priceand aggregate cost data (2) we cover 25000 products that thesupermarkets carry rather than a single product category (3) ourmenu cost gures do not include all components of menu costsand (4) there could be differences in wage rates that may be im-portant given the signicance of the labor cost component inmenu costs

V2 The Effect of Menu Costs on the Price Change Activity of theSupermarkets

In this section we present evidence which suggests that thesemenu costs may be forming a barrier to price change activity Tobegin with consider the effect of the item pricing law on the pricechange activity of Chain E The data on the weekly frequency ofprice changes in each chain are displayed in the last two rows ofTable I According to these gures the average weekly frequencyof price changes in Chain E is only 1578 Thus on average ChainE changes the prices of only 631 percent of its products eachweek In contrast the average weekly frequency of price changesat Chains AndashD ranges from 3223 to 4316 for the four-chain aver-age of 3916 price changes weekly So Chains AndashD change priceson 1289 to 1726 percent of their products each week yielding afour-chain average of 1566 percent Thus Chain E which facesthe item pricing law changes prices only about one-third timesas frequently as do Chains AndashD30

Moreover within Chain E there are 400 products that areexempt from the item pricing law and thereby face lower menucosts We nd that there are an average of 83 weekly pricechanges for these products yielding 21 percent of these productschanging prices So within Chain E they change prices over threetimes as frequently for products with lower menu costs than for

roughly equals one-half of their target net prot per item which seemssubstantial

30 However note that our comparison of the two types of chains may not becompletely ceteris paribus because these stores are located in different states andtherefore there may be other chain-specic factors (in addition to item pricinglaws) that distinguish these stores We do not have any specic information onthese differences We do know however that the stores in these chains are similarin size and carry similar sets of products

QUARTERLY JOURNAL OF ECONOMICS814

the products with higher menu costs Note that this nding is onthe price change activity within the same chain offering almost anatural experiment on the impact of menu costs on the chainrsquospricing behavior Hence we provide evidence both across chainsas well as across products within a chain that as the costs ofchanging price go up the frequency of price changes goes downThus the menu costs we nd are signicant enough to affect thechainrsquos price change practice

We also have additional evidence from Chains A B and Dabout these menu costs being a barrier to certain price changesand it is summarized in Table V According to the Price Manage-ment Department of Chain A the chain experiences cost in-creases on 860 products in an average week to which it wouldlike to react with a price increase31 However on average 22 per-cent of these price increases are not implemented immediatelybecause the cost of changing prices for these products is too highto make it economically worthwhile Figures of the same magni-tude were reported by other chains For example Chain D experi-ences cost increases for 961 products in an average week Out ofthese the chain adjusts prices of only 633 products The re-maining 34 percent of the prices are left unadjusted because ofthe menu costs Similarly Chain B nds it economically ineffi-cient to adjust prices of 508 ie 30 percent of its products eachweek because of menu costs This provides additional evidencethat the menu costs incurred by these chains are preventing priceadjustments to some costs changes leading to price rigidities ofthe products involved32 Note that although we do not have simi-lar data for Chain E we would expect signicantly lower num-bers on this measure at that chain These gures also suggest anupper bound on the benet of complete price exibility under thecurrent pricing practice of weekly price adjustments Howeverif new technologies (eg ESL systems) and new pricing prac-tices (eg a decentralization of the price change decisions) are

31 Our data contain information only on the frequency of cost increasesAlthough it is more than likely that the supermarkets are experiencing cost de-creases as well our data set contained no information on such decreases

32 Menu costs may even be playing a role in the observed movement towardpricing strategies that rely on fewer price changes such as EDLP [Blattberg andNeslin 1989 Lattin and Ortmeyer 1991 Marketing News April 13 1992 p 8]According to Progressive Grocer [November 1992 p 50] ldquoA growing number ofoperators say they have switched from high-low pricing [to EDLP] They cite theinefciencies of making frequent price changes rdquo Similarly Hoch Dreze andPurk [1994 p 16] state that EDLP lowers operating costs by lowering ldquo in-store labor costs because of less frequent changeovers in special displaysrdquo

adopted allowing a fundamental change in the way the pricingmechanism is currently set the managers could consider morefrequent price change activity (eg multiple times each week) asmenu costs go down

In this paper we measure the menu costs at the chainsrsquo cur-rent level of price change activity It may be worthwhile to specu-late on the shape of the cost function relating menu costs to thefrequency of price changes by assessing how these costs wouldchange if the price change activity were to increase or to decreaseIt seems likely that many of the costs we report in this paper will(approximately) change linearly with additional price changeswithin the current range of price changes the chains are under-taking (plus or minus perhaps a thousand per week) For ex-ample the labor costs associated with changing a shelf price tagcosts of verifying price changes and the costs of mistakes oc-curring during this process all increase linearly with the fre-quency of price changes This is because most of the time-consuming steps involved in the price change process must berepeated each time an additional shelf price tag is changed (seeTable II) Further we were unable to nd many tasks that gener-ated signicant returns to scale It is unclear what cost savingsare available if the price change activity drops substantially be-

QUARTERLY JOURNAL OF ECONOMICS816

low the levels it is at now Clearly if price changes were nearzero or done less frequently than weekly (say monthly) therecould be major differences in these costs

What is less clear is how these costs would change at moreextreme levels of price change activity With less frequent pricechanges the menu costs could probably be reduced signicantlyalthough the cost of deciding what prices to set initially and thecost of putting the initial shelf price tags would still remain as alower bound of the menu cost However for achieving more priceexibility by changing prices more frequently (ie multiple timeseach week) substantial changes must be undertaken At presentthe supermarket chains are set up to make the majority of theirprice changes on a weekly basis with the appropriate systems inplace to make this process most efcient For example in orderto save costs and to have higher quality price tags (eg withcolor more details greater clarity glossy etc) the chains oftensend new price tag requests to a printing shop which takes threedays to print and deliver the labels to each store Then giventhe large number of price changes taking place and the goals ofminimizing customer disruptions and labor costs (such as over-time pay) and coordinating with advertised price promotions theprices are changed in the store over a two-to-three-day period (seeTable VI) The combination of these schedule and built-in lags isacceptable under the current practice of changing prices weeklybut would have to be adjusted dramatically to allow for signifi-cantly more frequent price changes on a regular basis

Perhaps even more imposing are the costs of changing themanagerial costs associated with the current weekly system ofprice changes The process of pricing at this organizational levelis not a self-contained activity taking place in isolation from otheroperations of the supermarket management Rather it is a partof a larger system of business decisions and operations The cur-rent process of operations (such as data collection and theiranalysis management meetings coordination of the decisionsacross functional areas etc) is set up to function on a weeklybasis33 Further these management accounting and logisticssystems are currently built around a tremendous amount of in-

34 For example under the current system a chainwide category manageroperating at the corporate headquarters needs to study and assess numerouspieces of detailed information such as competitorsrsquo price and sale information fromthe last week the past weekrsquos sales at the own chain manufacturersupplier pro-motions wholesale price reductions coop allowances new product offerings shelfspace decisions coordination with newspaper advertising logistics at the ware-houses as well as at each store store differences in terms of customer characteris-tics and competitive environments productshelf selection and layout etc

35 If the supermarket chains indeed restructure the entire price change pro-cess and begin to change prices much more frequently (say two-to-three times aweek) on a regular basis then the shape of this cost function could change in anunpredictable way

V3 Relating Our Findings to the Existing Theoretical Models ofMenu Costs

In order to assess the magnitude of these menu cost guresin the context of the existing theoretical menu cost literatureconsider the following calculation experiments done within theframework of two theoretical menu cost models Blanchard andKiyotaki [1987] study a general equilibrium menu cost modelwith monopolistic competition and with unit elasticity of aggre-gate demand with respect to real money balances According totheir calculations menu costs of the magnitude of 008 percent ofrevenues which they consider ldquovery smallrdquo may be sufcient toprevent adjustment of prices Ball and Romer [1990] conductsimilar calculations in the framework of a model with imperfectcompetition and menu costs They nd that for plausible markupand labor elasticity parameter values menu costs needed to pre-vent price adjustment are 070 percent of revenues which as theysuggest are nonnegligible For smaller menu costs eg 004 per-cent of the revenue which Ball and Romer consider ldquotrivialrdquo im-plausibly large values of markup and labor elasticity parametersare needed to prevent price adjustment to monetary shocks

According to the gures in Table IV the reported menu costto revenues ratio for Chains AndashD averages 070 percent rangingfrom 061 percent to 076 percent These are signicantly largerthan the ldquotrivialrdquo 004 or 008 percent gures mentioned abovesuggesting that the menu cost gures we nd here are nontrivialFurther under the model and parameter values considered byBlanchard and Kiyotaki [1987] the menu cost gures we nd arehigher than the theoretical minimum needed to form a barrier toprice adjustments Under the model and parameter values con-sidered by Ball and Romer [1990] the reported menu costreve-nue ratio for all but one chain reaches or crosses the theoreticalthreshold of 070 needed to form a barrier to price adjustmentsThe existence of numerous unmeasured menu cost componentsdiscussed in subsection III5 also raises the possibility that theactual menu costs incurred by these chains are signicantlyhigher than that threshold This suggests that the menu costs wereport may be large enough to form a barrier to nominal priceadjustments when interpreted in the context of these models

An issue of interest in this literature is time-dependent ver-sus state-dependent pricing rules (see for example Caplin andLeahy [1991]) The evidence from our data set on the timing of

THE MAGNITUDE OF MENU COSTS 819

price changes suggests that the price change decisions in thesesupermarkets have a strong time-dependent price-setting ele-ment36 For example according to Table VI the prices in Chain Aare changed weekly according to the following schedule the pricechanges of general merchandise that is advertised is done Satur-day nights grocery and produce prices are changed Sundaynights the rest of the general merchandise prices are changed onMonday nights and the prices of advertised grocery items arechanged on Tuesday nights Thus as the gures in Table VI indi-cate over 96 percent of the price changes are done during Sundayand Monday nights However this does not imply that state-dependent pricing rules are unimportant Even if price changesacross product categories follow a prescheduled weekly time ta-ble the prices of which products to change is likely to be a state-dependent decision For example it could depend on changes insupply and demand conditions such as competitorsrsquo price changedecisions Indeed Levy Dutta and Bergen [1996] use retailstore-level orange juice price and cost data to demonstrate thatthe extent of price response to cost shocks that is the extent ofprice rigidity may depend on the nature of supply shocks37

We do not want to overstate the usefulness of our data fordirectly addressing the issue of monetary nonneutrality On onehand authors such as Caplin and Spulber [1987] have demon-strated that under certain conditions individual price rigiditymay not be sufcient for aggregate price rigidity but unfortu-nately our data do not speak directly to this issue38 On the otherhand authors such as Akerlof and Yellen [1985] Mankiw [1985]Parkin [1986] and Caplin and Leahy [1997] have shown that even

36 Danziger [1983] Caballero [1989] and Ball and Mankiw [1994] suggestthat time-dependent price adjustment of the type documented here can be optimalif the cost of gathering information about the state exceeds the cost of making theprice adjustment itself

37 We also considered the possibility of convexities in the cost of changingprices Our data do not suggest many convexities since the labor time spent inthe price tag change process the cost of printing and delivering price tags andin-store supervision time do not change with the size of a price change The onlymeasurable component of menu costs that could be convex is the cost of mistakesmade the larger the price change the higher the probability of a customer notic-ing the mistake and the larger the amount required to be refunded as compensa-tion Among the unmeasured components of menu cost the cost of corporatemanagerial time may increase with the size of a price change because larger pricechanges may require more serious consideration

38 Also see Balke and Wynne [1996] and Bryan and Cecchetti [1996] Sincewe do not have measures of how menu costs change over time our data also havelittle to say about time variation in menu costs or about the relationship betweenmenu costs and ination which during the period of the data collection (1991ndash1992) averaged about 3 percent annually

QUARTERLY JOURNAL OF ECONOMICS820

small menu costs can be relevant since they may be sufcient togenerate substantial aggregate nominal rigidity and thus largebusiness cycles Therefore as Blinder [1994] Kashyap [1995]and Slade [1996a] emphasize it is important to search for directevidence that such costs are indeed present at the micro level Bydirectly identifying documenting and measuring the magnitudeof menu costs at the store level we are taking an important stepin that direction

VI CONCLUSION AND FUTURE RESEARCH

Our main contribution is that we provide direct microeco-nomic evidence on the actual magnitude of menu costs for fourlarge U S retail supermarket chains The annual menu costs perstore at these chains average $105887 comprising 070 percentof revenues 352 percent of net prot margins and $052 perprice change on average

Further we provide evidence which suggests that thesemenu costs may be forming a barrier to price changes Specifi-cally we show that (1) supermarket chains not subject to itempricing law change prices two and a half times more frequentlythan the chain that is subject to the law (2) within the chain thatis subject to the item pricing law they change prices over threetimes as frequently for products that are exempt from this lawthan for the products which are subject to this law and (3) wend that these chains do not adjust prices of up to one-third ofthe products for which they face cost increases because of menucost considerations

When we relate these ndings to the existing theoreticalmodels of menu costs we conclude that the magnitude of menucosts we nd is large enough to be capable of having macroeco-nomic signicance Specically when considered in the context ofthe theoretical menu cost models of Blanchard and Kiyotaki[1987] and Ball and Romer [1990] we nd that the menu costgures we report are ldquonontrivialrdquo and their relative magnitudescross the minimum theoretical threshold needed to form a barrierto price adjustments

Despite the high relative magnitude of the marginal cost ofchanging price that we found the data still indicate frequentweekly price changes This is because of the high marginal bene-t of changing price which is due to the erce competition foundin the retail supermarket industry That marginal benets may

THE MAGNITUDE OF MENU COSTS 821

outweigh the marginal costs of changing prices in this industryhowever does not rule out the possibility that menu costs of themagnitude we nd here can create substantial nominal rigidityin other industries or markets In less competitive industries andmarkets menu costs of the type and magnitude we documenthere are likely to have a bigger impact on the frequency of priceadjustment and consequently on the degree of price rigidity

At a minimum the direct dollar measures of menu costs wereport here can be used as a starting point for future research onmeasuring their magnitude in other industries and establish-ments We anticipate that these menu costs will be similar inother markets which rely on posted prices (such as drugstoresdepartment stores etc) because the steps involved in the pricechange process are likely to be similar What may differ are thefrequency of price changes and the labor wage rates at thesestores For example since supermarket chains change thousandsof prices each week the total annual menu costs incurred bythese chains per store are likely to be high in comparison to otherretail formats such as chain drugstores or department storesThere are however a variety of industries for which the stepsinvolved in changing prices would be signicantly different fromthose reported in our study For example business-to-businesssales which often rely on a sales force will require changes in thelist price sheets changes in the instructions to the sales forcewhich may include education and discussion with the salespeoplein the company and so forth These business-to-business pricesalso often have more complex pricing schemes including quantitydiscounts bundling and individually negotiated prices As an-other example the composition of the cost of changing the news-stand prices of magazines [Cecchetti 1986] or the prices ofproducts sold through catalogs [Kashyap 1995] are different frommany of the menu cost components we discuss here Further thending that a centralization of pricing decisions makes the store-level managerial component of menu cost relatively small sug-gests that the managerial menu costs likely are highest insettings where price change decisions are decentralized Thus fu-ture empirical work should look at menu cost and its compositionin a variety of other industries markets and products with bothcentralized as well as decentralized price change decisions in or-der to see whether the magnitude of these costs can be general-ized and benchmarks can be established Further there aretechnological changes taking place in this and other industries

that promise to alter the structure of menu costs which deserveattention At the theoretical level our ndings suggest that it maybe worthwhile to explore models which incorporate the idea ofitem pricing laws as an additional component of menu costs

per store27 According to the second row of Table IV the ratio ofmenu costs to revenues for Chains AndashD ranges between 061ndash076percent averaging 070 percent28 We relate the size of thesegures to the existing theoretical menu cost models in sub-section V3

Net prot margin which measures the revenues minus allcosts is approximately 1ndash3 percent of revenues for these chains[Montgomery 1994] so we use 2 percent as a working averageThe reason for the low prot rate in this industry is the intensecompetition [Calatone et al 1989] especially at the regional level[Chevalier 1995] which has been increasing since the early 1990s[Progressive Grocer November 1992 p 50] It follows that theaverage store protability for these chains equals $301054 peryear Therefore the ratio of total menu cost to net margin forChains AndashD ranges between 304ndash379 percent for an average of352 percent Thus the menu costs we report in this study repre-sent a signicant share of supermarketsrsquo prots

Another way to look at the menu cost gures we report is toexpress them relative to the frequency of price changes In thelast row of Table IV we present the menu cost gures per pricechange for each chain As the table indicates the cost of changinga price in Chains AndashD ranges between $046ndash$068 for an averageof $052 For Chain E the gure is substantially larger $133 perprice change29 These gures are lower than the estimated cost of

27 This is the average of two different estimates $12945432 and$17160000 The source of the rst gure is internal record of a supermarketchain of the type and size studied here The second gure comes from Supermar-ket Business [1993 p 52]

28 We also measured the menu costs in terms of controllable operating ex-penses (which are the portion of costs that the retailer has direct control over andtherefore are often the costs that the retailer is most focused on managing) andgross margins (which measure the supermarket revenues minus direct cost of theproducts it sells) We nd that the menu costs comprise 313 percent of controlla-ble operating expenses and 281 percent of gross margins at these chains on aver-age Finally if we measure the menu costs relative to the number of productscarried per store (about 25000) then we nd that the menu costs per productaverage $423 for Chains AndashD See Table IV and its footnotes for details

29 We can also try to express the menu cost gures relative to the numberof individual items sold by these chains each year (Note the difference betweennumber of products carried and number of items sold As an example a TartarControl Crest 8oz would be considered a product carried and 300 units of themsold per year would be considered number of items sold) Using $170 as the aver-age price of all the products sold we nd that the menu cost per item sold for thefour chains is in the range of $00103ndash$00129 for an average of $00119 (see TableIV second to last row) To see the relative magnitude of these gures note thataccording to Berkowitz Kerin and Rudelius [1986 p 319] the goal of the super-market chains of the type we study ldquo is to make 1 penny of prot on each dollarof salesrdquo Thus menu cost per item sold when adjusted for the average price

THE MAGNITUDE OF MENU COSTS 813

$200ndash$300 per price change reported by Slade [1996a] Thereare several possible reasons for this (1) our menu cost gures arebased on actual measurements of the resources that go into theprice change process whereas she estimates menu costs econo-metrically as model coefcients using a mix of store-level priceand aggregate cost data (2) we cover 25000 products that thesupermarkets carry rather than a single product category (3) ourmenu cost gures do not include all components of menu costsand (4) there could be differences in wage rates that may be im-portant given the signicance of the labor cost component inmenu costs

V2 The Effect of Menu Costs on the Price Change Activity of theSupermarkets

In this section we present evidence which suggests that thesemenu costs may be forming a barrier to price change activity Tobegin with consider the effect of the item pricing law on the pricechange activity of Chain E The data on the weekly frequency ofprice changes in each chain are displayed in the last two rows ofTable I According to these gures the average weekly frequencyof price changes in Chain E is only 1578 Thus on average ChainE changes the prices of only 631 percent of its products eachweek In contrast the average weekly frequency of price changesat Chains AndashD ranges from 3223 to 4316 for the four-chain aver-age of 3916 price changes weekly So Chains AndashD change priceson 1289 to 1726 percent of their products each week yielding afour-chain average of 1566 percent Thus Chain E which facesthe item pricing law changes prices only about one-third timesas frequently as do Chains AndashD30

Moreover within Chain E there are 400 products that areexempt from the item pricing law and thereby face lower menucosts We nd that there are an average of 83 weekly pricechanges for these products yielding 21 percent of these productschanging prices So within Chain E they change prices over threetimes as frequently for products with lower menu costs than for

roughly equals one-half of their target net prot per item which seemssubstantial

30 However note that our comparison of the two types of chains may not becompletely ceteris paribus because these stores are located in different states andtherefore there may be other chain-specic factors (in addition to item pricinglaws) that distinguish these stores We do not have any specic information onthese differences We do know however that the stores in these chains are similarin size and carry similar sets of products

QUARTERLY JOURNAL OF ECONOMICS814

the products with higher menu costs Note that this nding is onthe price change activity within the same chain offering almost anatural experiment on the impact of menu costs on the chainrsquospricing behavior Hence we provide evidence both across chainsas well as across products within a chain that as the costs ofchanging price go up the frequency of price changes goes downThus the menu costs we nd are signicant enough to affect thechainrsquos price change practice

We also have additional evidence from Chains A B and Dabout these menu costs being a barrier to certain price changesand it is summarized in Table V According to the Price Manage-ment Department of Chain A the chain experiences cost in-creases on 860 products in an average week to which it wouldlike to react with a price increase31 However on average 22 per-cent of these price increases are not implemented immediatelybecause the cost of changing prices for these products is too highto make it economically worthwhile Figures of the same magni-tude were reported by other chains For example Chain D experi-ences cost increases for 961 products in an average week Out ofthese the chain adjusts prices of only 633 products The re-maining 34 percent of the prices are left unadjusted because ofthe menu costs Similarly Chain B nds it economically ineffi-cient to adjust prices of 508 ie 30 percent of its products eachweek because of menu costs This provides additional evidencethat the menu costs incurred by these chains are preventing priceadjustments to some costs changes leading to price rigidities ofthe products involved32 Note that although we do not have simi-lar data for Chain E we would expect signicantly lower num-bers on this measure at that chain These gures also suggest anupper bound on the benet of complete price exibility under thecurrent pricing practice of weekly price adjustments Howeverif new technologies (eg ESL systems) and new pricing prac-tices (eg a decentralization of the price change decisions) are

31 Our data contain information only on the frequency of cost increasesAlthough it is more than likely that the supermarkets are experiencing cost de-creases as well our data set contained no information on such decreases

32 Menu costs may even be playing a role in the observed movement towardpricing strategies that rely on fewer price changes such as EDLP [Blattberg andNeslin 1989 Lattin and Ortmeyer 1991 Marketing News April 13 1992 p 8]According to Progressive Grocer [November 1992 p 50] ldquoA growing number ofoperators say they have switched from high-low pricing [to EDLP] They cite theinefciencies of making frequent price changes rdquo Similarly Hoch Dreze andPurk [1994 p 16] state that EDLP lowers operating costs by lowering ldquo in-store labor costs because of less frequent changeovers in special displaysrdquo

adopted allowing a fundamental change in the way the pricingmechanism is currently set the managers could consider morefrequent price change activity (eg multiple times each week) asmenu costs go down

In this paper we measure the menu costs at the chainsrsquo cur-rent level of price change activity It may be worthwhile to specu-late on the shape of the cost function relating menu costs to thefrequency of price changes by assessing how these costs wouldchange if the price change activity were to increase or to decreaseIt seems likely that many of the costs we report in this paper will(approximately) change linearly with additional price changeswithin the current range of price changes the chains are under-taking (plus or minus perhaps a thousand per week) For ex-ample the labor costs associated with changing a shelf price tagcosts of verifying price changes and the costs of mistakes oc-curring during this process all increase linearly with the fre-quency of price changes This is because most of the time-consuming steps involved in the price change process must berepeated each time an additional shelf price tag is changed (seeTable II) Further we were unable to nd many tasks that gener-ated signicant returns to scale It is unclear what cost savingsare available if the price change activity drops substantially be-

low the levels it is at now Clearly if price changes were nearzero or done less frequently than weekly (say monthly) therecould be major differences in these costs

What is less clear is how these costs would change at moreextreme levels of price change activity With less frequent pricechanges the menu costs could probably be reduced signicantlyalthough the cost of deciding what prices to set initially and thecost of putting the initial shelf price tags would still remain as alower bound of the menu cost However for achieving more priceexibility by changing prices more frequently (ie multiple timeseach week) substantial changes must be undertaken At presentthe supermarket chains are set up to make the majority of theirprice changes on a weekly basis with the appropriate systems inplace to make this process most efcient For example in orderto save costs and to have higher quality price tags (eg withcolor more details greater clarity glossy etc) the chains oftensend new price tag requests to a printing shop which takes threedays to print and deliver the labels to each store Then giventhe large number of price changes taking place and the goals ofminimizing customer disruptions and labor costs (such as over-time pay) and coordinating with advertised price promotions theprices are changed in the store over a two-to-three-day period (seeTable VI) The combination of these schedule and built-in lags isacceptable under the current practice of changing prices weeklybut would have to be adjusted dramatically to allow for signifi-cantly more frequent price changes on a regular basis

Perhaps even more imposing are the costs of changing themanagerial costs associated with the current weekly system ofprice changes The process of pricing at this organizational levelis not a self-contained activity taking place in isolation from otheroperations of the supermarket management Rather it is a partof a larger system of business decisions and operations The cur-rent process of operations (such as data collection and theiranalysis management meetings coordination of the decisionsacross functional areas etc) is set up to function on a weeklybasis33 Further these management accounting and logisticssystems are currently built around a tremendous amount of in-

34 For example under the current system a chainwide category manageroperating at the corporate headquarters needs to study and assess numerouspieces of detailed information such as competitorsrsquo price and sale information fromthe last week the past weekrsquos sales at the own chain manufacturersupplier pro-motions wholesale price reductions coop allowances new product offerings shelfspace decisions coordination with newspaper advertising logistics at the ware-houses as well as at each store store differences in terms of customer characteris-tics and competitive environments productshelf selection and layout etc

35 If the supermarket chains indeed restructure the entire price change pro-cess and begin to change prices much more frequently (say two-to-three times aweek) on a regular basis then the shape of this cost function could change in anunpredictable way

V3 Relating Our Findings to the Existing Theoretical Models ofMenu Costs

In order to assess the magnitude of these menu cost guresin the context of the existing theoretical menu cost literatureconsider the following calculation experiments done within theframework of two theoretical menu cost models Blanchard andKiyotaki [1987] study a general equilibrium menu cost modelwith monopolistic competition and with unit elasticity of aggre-gate demand with respect to real money balances According totheir calculations menu costs of the magnitude of 008 percent ofrevenues which they consider ldquovery smallrdquo may be sufcient toprevent adjustment of prices Ball and Romer [1990] conductsimilar calculations in the framework of a model with imperfectcompetition and menu costs They nd that for plausible markupand labor elasticity parameter values menu costs needed to pre-vent price adjustment are 070 percent of revenues which as theysuggest are nonnegligible For smaller menu costs eg 004 per-cent of the revenue which Ball and Romer consider ldquotrivialrdquo im-plausibly large values of markup and labor elasticity parametersare needed to prevent price adjustment to monetary shocks

According to the gures in Table IV the reported menu costto revenues ratio for Chains AndashD averages 070 percent rangingfrom 061 percent to 076 percent These are signicantly largerthan the ldquotrivialrdquo 004 or 008 percent gures mentioned abovesuggesting that the menu cost gures we nd here are nontrivialFurther under the model and parameter values considered byBlanchard and Kiyotaki [1987] the menu cost gures we nd arehigher than the theoretical minimum needed to form a barrier toprice adjustments Under the model and parameter values con-sidered by Ball and Romer [1990] the reported menu costreve-nue ratio for all but one chain reaches or crosses the theoreticalthreshold of 070 needed to form a barrier to price adjustmentsThe existence of numerous unmeasured menu cost componentsdiscussed in subsection III5 also raises the possibility that theactual menu costs incurred by these chains are signicantlyhigher than that threshold This suggests that the menu costs wereport may be large enough to form a barrier to nominal priceadjustments when interpreted in the context of these models

An issue of interest in this literature is time-dependent ver-sus state-dependent pricing rules (see for example Caplin andLeahy [1991]) The evidence from our data set on the timing of

price changes suggests that the price change decisions in thesesupermarkets have a strong time-dependent price-setting ele-ment36 For example according to Table VI the prices in Chain Aare changed weekly according to the following schedule the pricechanges of general merchandise that is advertised is done Satur-day nights grocery and produce prices are changed Sundaynights the rest of the general merchandise prices are changed onMonday nights and the prices of advertised grocery items arechanged on Tuesday nights Thus as the gures in Table VI indi-cate over 96 percent of the price changes are done during Sundayand Monday nights However this does not imply that state-dependent pricing rules are unimportant Even if price changesacross product categories follow a prescheduled weekly time ta-ble the prices of which products to change is likely to be a state-dependent decision For example it could depend on changes insupply and demand conditions such as competitorsrsquo price changedecisions Indeed Levy Dutta and Bergen [1996] use retailstore-level orange juice price and cost data to demonstrate thatthe extent of price response to cost shocks that is the extent ofprice rigidity may depend on the nature of supply shocks37

We do not want to overstate the usefulness of our data fordirectly addressing the issue of monetary nonneutrality On onehand authors such as Caplin and Spulber [1987] have demon-strated that under certain conditions individual price rigiditymay not be sufcient for aggregate price rigidity but unfortu-nately our data do not speak directly to this issue38 On the otherhand authors such as Akerlof and Yellen [1985] Mankiw [1985]Parkin [1986] and Caplin and Leahy [1997] have shown that even

36 Danziger [1983] Caballero [1989] and Ball and Mankiw [1994] suggestthat time-dependent price adjustment of the type documented here can be optimalif the cost of gathering information about the state exceeds the cost of making theprice adjustment itself

37 We also considered the possibility of convexities in the cost of changingprices Our data do not suggest many convexities since the labor time spent inthe price tag change process the cost of printing and delivering price tags andin-store supervision time do not change with the size of a price change The onlymeasurable component of menu costs that could be convex is the cost of mistakesmade the larger the price change the higher the probability of a customer notic-ing the mistake and the larger the amount required to be refunded as compensa-tion Among the unmeasured components of menu cost the cost of corporatemanagerial time may increase with the size of a price change because larger pricechanges may require more serious consideration

38 Also see Balke and Wynne [1996] and Bryan and Cecchetti [1996] Sincewe do not have measures of how menu costs change over time our data also havelittle to say about time variation in menu costs or about the relationship betweenmenu costs and ination which during the period of the data collection (1991ndash1992) averaged about 3 percent annually

QUARTERLY JOURNAL OF ECONOMICS820

small menu costs can be relevant since they may be sufcient togenerate substantial aggregate nominal rigidity and thus largebusiness cycles Therefore as Blinder [1994] Kashyap [1995]and Slade [1996a] emphasize it is important to search for directevidence that such costs are indeed present at the micro level Bydirectly identifying documenting and measuring the magnitudeof menu costs at the store level we are taking an important stepin that direction

VI CONCLUSION AND FUTURE RESEARCH

Our main contribution is that we provide direct microeco-nomic evidence on the actual magnitude of menu costs for fourlarge U S retail supermarket chains The annual menu costs perstore at these chains average $105887 comprising 070 percentof revenues 352 percent of net prot margins and $052 perprice change on average

Further we provide evidence which suggests that thesemenu costs may be forming a barrier to price changes Specifi-cally we show that (1) supermarket chains not subject to itempricing law change prices two and a half times more frequentlythan the chain that is subject to the law (2) within the chain thatis subject to the item pricing law they change prices over threetimes as frequently for products that are exempt from this lawthan for the products which are subject to this law and (3) wend that these chains do not adjust prices of up to one-third ofthe products for which they face cost increases because of menucost considerations

When we relate these ndings to the existing theoreticalmodels of menu costs we conclude that the magnitude of menucosts we nd is large enough to be capable of having macroeco-nomic signicance Specically when considered in the context ofthe theoretical menu cost models of Blanchard and Kiyotaki[1987] and Ball and Romer [1990] we nd that the menu costgures we report are ldquonontrivialrdquo and their relative magnitudescross the minimum theoretical threshold needed to form a barrierto price adjustments

Despite the high relative magnitude of the marginal cost ofchanging price that we found the data still indicate frequentweekly price changes This is because of the high marginal bene-t of changing price which is due to the erce competition foundin the retail supermarket industry That marginal benets may

THE MAGNITUDE OF MENU COSTS 821

outweigh the marginal costs of changing prices in this industryhowever does not rule out the possibility that menu costs of themagnitude we nd here can create substantial nominal rigidityin other industries or markets In less competitive industries andmarkets menu costs of the type and magnitude we documenthere are likely to have a bigger impact on the frequency of priceadjustment and consequently on the degree of price rigidity

At a minimum the direct dollar measures of menu costs wereport here can be used as a starting point for future research onmeasuring their magnitude in other industries and establish-ments We anticipate that these menu costs will be similar inother markets which rely on posted prices (such as drugstoresdepartment stores etc) because the steps involved in the pricechange process are likely to be similar What may differ are thefrequency of price changes and the labor wage rates at thesestores For example since supermarket chains change thousandsof prices each week the total annual menu costs incurred bythese chains per store are likely to be high in comparison to otherretail formats such as chain drugstores or department storesThere are however a variety of industries for which the stepsinvolved in changing prices would be signicantly different fromthose reported in our study For example business-to-businesssales which often rely on a sales force will require changes in thelist price sheets changes in the instructions to the sales forcewhich may include education and discussion with the salespeoplein the company and so forth These business-to-business pricesalso often have more complex pricing schemes including quantitydiscounts bundling and individually negotiated prices As an-other example the composition of the cost of changing the news-stand prices of magazines [Cecchetti 1986] or the prices ofproducts sold through catalogs [Kashyap 1995] are different frommany of the menu cost components we discuss here Further thending that a centralization of pricing decisions makes the store-level managerial component of menu cost relatively small sug-gests that the managerial menu costs likely are highest insettings where price change decisions are decentralized Thus fu-ture empirical work should look at menu cost and its compositionin a variety of other industries markets and products with bothcentralized as well as decentralized price change decisions in or-der to see whether the magnitude of these costs can be general-ized and benchmarks can be established Further there aretechnological changes taking place in this and other industries

that promise to alter the structure of menu costs which deserveattention At the theoretical level our ndings suggest that it maybe worthwhile to explore models which incorporate the idea ofitem pricing laws as an additional component of menu costs

per store27 According to the second row of Table IV the ratio ofmenu costs to revenues for Chains AndashD ranges between 061ndash076percent averaging 070 percent28 We relate the size of thesegures to the existing theoretical menu cost models in sub-section V3

Net prot margin which measures the revenues minus allcosts is approximately 1ndash3 percent of revenues for these chains[Montgomery 1994] so we use 2 percent as a working averageThe reason for the low prot rate in this industry is the intensecompetition [Calatone et al 1989] especially at the regional level[Chevalier 1995] which has been increasing since the early 1990s[Progressive Grocer November 1992 p 50] It follows that theaverage store protability for these chains equals $301054 peryear Therefore the ratio of total menu cost to net margin forChains AndashD ranges between 304ndash379 percent for an average of352 percent Thus the menu costs we report in this study repre-sent a signicant share of supermarketsrsquo prots

Another way to look at the menu cost gures we report is toexpress them relative to the frequency of price changes In thelast row of Table IV we present the menu cost gures per pricechange for each chain As the table indicates the cost of changinga price in Chains AndashD ranges between $046ndash$068 for an averageof $052 For Chain E the gure is substantially larger $133 perprice change29 These gures are lower than the estimated cost of

27 This is the average of two different estimates $12945432 and$17160000 The source of the rst gure is internal record of a supermarketchain of the type and size studied here The second gure comes from Supermar-ket Business [1993 p 52]

28 We also measured the menu costs in terms of controllable operating ex-penses (which are the portion of costs that the retailer has direct control over andtherefore are often the costs that the retailer is most focused on managing) andgross margins (which measure the supermarket revenues minus direct cost of theproducts it sells) We nd that the menu costs comprise 313 percent of controlla-ble operating expenses and 281 percent of gross margins at these chains on aver-age Finally if we measure the menu costs relative to the number of productscarried per store (about 25000) then we nd that the menu costs per productaverage $423 for Chains AndashD See Table IV and its footnotes for details

29 We can also try to express the menu cost gures relative to the numberof individual items sold by these chains each year (Note the difference betweennumber of products carried and number of items sold As an example a TartarControl Crest 8oz would be considered a product carried and 300 units of themsold per year would be considered number of items sold) Using $170 as the aver-age price of all the products sold we nd that the menu cost per item sold for thefour chains is in the range of $00103ndash$00129 for an average of $00119 (see TableIV second to last row) To see the relative magnitude of these gures note thataccording to Berkowitz Kerin and Rudelius [1986 p 319] the goal of the super-market chains of the type we study ldquo is to make 1 penny of prot on each dollarof salesrdquo Thus menu cost per item sold when adjusted for the average price

THE MAGNITUDE OF MENU COSTS 813

$200ndash$300 per price change reported by Slade [1996a] Thereare several possible reasons for this (1) our menu cost gures arebased on actual measurements of the resources that go into theprice change process whereas she estimates menu costs econo-metrically as model coefcients using a mix of store-level priceand aggregate cost data (2) we cover 25000 products that thesupermarkets carry rather than a single product category (3) ourmenu cost gures do not include all components of menu costsand (4) there could be differences in wage rates that may be im-portant given the signicance of the labor cost component inmenu costs

V2 The Effect of Menu Costs on the Price Change Activity of theSupermarkets

In this section we present evidence which suggests that thesemenu costs may be forming a barrier to price change activity Tobegin with consider the effect of the item pricing law on the pricechange activity of Chain E The data on the weekly frequency ofprice changes in each chain are displayed in the last two rows ofTable I According to these gures the average weekly frequencyof price changes in Chain E is only 1578 Thus on average ChainE changes the prices of only 631 percent of its products eachweek In contrast the average weekly frequency of price changesat Chains AndashD ranges from 3223 to 4316 for the four-chain aver-age of 3916 price changes weekly So Chains AndashD change priceson 1289 to 1726 percent of their products each week yielding afour-chain average of 1566 percent Thus Chain E which facesthe item pricing law changes prices only about one-third timesas frequently as do Chains AndashD30

Moreover within Chain E there are 400 products that areexempt from the item pricing law and thereby face lower menucosts We nd that there are an average of 83 weekly pricechanges for these products yielding 21 percent of these productschanging prices So within Chain E they change prices over threetimes as frequently for products with lower menu costs than for

roughly equals one-half of their target net prot per item which seemssubstantial

30 However note that our comparison of the two types of chains may not becompletely ceteris paribus because these stores are located in different states andtherefore there may be other chain-specic factors (in addition to item pricinglaws) that distinguish these stores We do not have any specic information onthese differences We do know however that the stores in these chains are similarin size and carry similar sets of products

QUARTERLY JOURNAL OF ECONOMICS814

the products with higher menu costs Note that this nding is onthe price change activity within the same chain offering almost anatural experiment on the impact of menu costs on the chainrsquospricing behavior Hence we provide evidence both across chainsas well as across products within a chain that as the costs ofchanging price go up the frequency of price changes goes downThus the menu costs we nd are signicant enough to affect thechainrsquos price change practice

We also have additional evidence from Chains A B and Dabout these menu costs being a barrier to certain price changesand it is summarized in Table V According to the Price Manage-ment Department of Chain A the chain experiences cost in-creases on 860 products in an average week to which it wouldlike to react with a price increase31 However on average 22 per-cent of these price increases are not implemented immediatelybecause the cost of changing prices for these products is too highto make it economically worthwhile Figures of the same magni-tude were reported by other chains For example Chain D experi-ences cost increases for 961 products in an average week Out ofthese the chain adjusts prices of only 633 products The re-maining 34 percent of the prices are left unadjusted because ofthe menu costs Similarly Chain B nds it economically ineffi-cient to adjust prices of 508 ie 30 percent of its products eachweek because of menu costs This provides additional evidencethat the menu costs incurred by these chains are preventing priceadjustments to some costs changes leading to price rigidities ofthe products involved32 Note that although we do not have simi-lar data for Chain E we would expect signicantly lower num-bers on this measure at that chain These gures also suggest anupper bound on the benet of complete price exibility under thecurrent pricing practice of weekly price adjustments Howeverif new technologies (eg ESL systems) and new pricing prac-tices (eg a decentralization of the price change decisions) are

31 Our data contain information only on the frequency of cost increasesAlthough it is more than likely that the supermarkets are experiencing cost de-creases as well our data set contained no information on such decreases

32 Menu costs may even be playing a role in the observed movement towardpricing strategies that rely on fewer price changes such as EDLP [Blattberg andNeslin 1989 Lattin and Ortmeyer 1991 Marketing News April 13 1992 p 8]According to Progressive Grocer [November 1992 p 50] ldquoA growing number ofoperators say they have switched from high-low pricing [to EDLP] They cite theinefciencies of making frequent price changes rdquo Similarly Hoch Dreze andPurk [1994 p 16] state that EDLP lowers operating costs by lowering ldquo in-store labor costs because of less frequent changeovers in special displaysrdquo

adopted allowing a fundamental change in the way the pricingmechanism is currently set the managers could consider morefrequent price change activity (eg multiple times each week) asmenu costs go down

In this paper we measure the menu costs at the chainsrsquo cur-rent level of price change activity It may be worthwhile to specu-late on the shape of the cost function relating menu costs to thefrequency of price changes by assessing how these costs wouldchange if the price change activity were to increase or to decreaseIt seems likely that many of the costs we report in this paper will(approximately) change linearly with additional price changeswithin the current range of price changes the chains are under-taking (plus or minus perhaps a thousand per week) For ex-ample the labor costs associated with changing a shelf price tagcosts of verifying price changes and the costs of mistakes oc-curring during this process all increase linearly with the fre-quency of price changes This is because most of the time-consuming steps involved in the price change process must berepeated each time an additional shelf price tag is changed (seeTable II) Further we were unable to nd many tasks that gener-ated signicant returns to scale It is unclear what cost savingsare available if the price change activity drops substantially be-

low the levels it is at now Clearly if price changes were nearzero or done less frequently than weekly (say monthly) therecould be major differences in these costs

What is less clear is how these costs would change at moreextreme levels of price change activity With less frequent pricechanges the menu costs could probably be reduced signicantlyalthough the cost of deciding what prices to set initially and thecost of putting the initial shelf price tags would still remain as alower bound of the menu cost However for achieving more priceexibility by changing prices more frequently (ie multiple timeseach week) substantial changes must be undertaken At presentthe supermarket chains are set up to make the majority of theirprice changes on a weekly basis with the appropriate systems inplace to make this process most efcient For example in orderto save costs and to have higher quality price tags (eg withcolor more details greater clarity glossy etc) the chains oftensend new price tag requests to a printing shop which takes threedays to print and deliver the labels to each store Then giventhe large number of price changes taking place and the goals ofminimizing customer disruptions and labor costs (such as over-time pay) and coordinating with advertised price promotions theprices are changed in the store over a two-to-three-day period (seeTable VI) The combination of these schedule and built-in lags isacceptable under the current practice of changing prices weeklybut would have to be adjusted dramatically to allow for signifi-cantly more frequent price changes on a regular basis

Perhaps even more imposing are the costs of changing themanagerial costs associated with the current weekly system ofprice changes The process of pricing at this organizational levelis not a self-contained activity taking place in isolation from otheroperations of the supermarket management Rather it is a partof a larger system of business decisions and operations The cur-rent process of operations (such as data collection and theiranalysis management meetings coordination of the decisionsacross functional areas etc) is set up to function on a weeklybasis33 Further these management accounting and logisticssystems are currently built around a tremendous amount of in-

35 If the supermarket chains indeed restructure the entire price change pro-cess and begin to change prices much more frequently (say two-to-three times aweek) on a regular basis then the shape of this cost function could change in anunpredictable way

V3 Relating Our Findings to the Existing Theoretical Models ofMenu Costs

In order to assess the magnitude of these menu cost guresin the context of the existing theoretical menu cost literatureconsider the following calculation experiments done within theframework of two theoretical menu cost models Blanchard andKiyotaki [1987] study a general equilibrium menu cost modelwith monopolistic competition and with unit elasticity of aggre-gate demand with respect to real money balances According totheir calculations menu costs of the magnitude of 008 percent ofrevenues which they consider ldquovery smallrdquo may be sufcient toprevent adjustment of prices Ball and Romer [1990] conductsimilar calculations in the framework of a model with imperfectcompetition and menu costs They nd that for plausible markupand labor elasticity parameter values menu costs needed to pre-vent price adjustment are 070 percent of revenues which as theysuggest are nonnegligible For smaller menu costs eg 004 per-cent of the revenue which Ball and Romer consider ldquotrivialrdquo im-plausibly large values of markup and labor elasticity parametersare needed to prevent price adjustment to monetary shocks

According to the gures in Table IV the reported menu costto revenues ratio for Chains AndashD averages 070 percent rangingfrom 061 percent to 076 percent These are signicantly largerthan the ldquotrivialrdquo 004 or 008 percent gures mentioned abovesuggesting that the menu cost gures we nd here are nontrivialFurther under the model and parameter values considered byBlanchard and Kiyotaki [1987] the menu cost gures we nd arehigher than the theoretical minimum needed to form a barrier toprice adjustments Under the model and parameter values con-sidered by Ball and Romer [1990] the reported menu costreve-nue ratio for all but one chain reaches or crosses the theoreticalthreshold of 070 needed to form a barrier to price adjustmentsThe existence of numerous unmeasured menu cost componentsdiscussed in subsection III5 also raises the possibility that theactual menu costs incurred by these chains are signicantlyhigher than that threshold This suggests that the menu costs wereport may be large enough to form a barrier to nominal priceadjustments when interpreted in the context of these models

An issue of interest in this literature is time-dependent ver-sus state-dependent pricing rules (see for example Caplin andLeahy [1991]) The evidence from our data set on the timing of

price changes suggests that the price change decisions in thesesupermarkets have a strong time-dependent price-setting ele-ment36 For example according to Table VI the prices in Chain Aare changed weekly according to the following schedule the pricechanges of general merchandise that is advertised is done Satur-day nights grocery and produce prices are changed Sundaynights the rest of the general merchandise prices are changed onMonday nights and the prices of advertised grocery items arechanged on Tuesday nights Thus as the gures in Table VI indi-cate over 96 percent of the price changes are done during Sundayand Monday nights However this does not imply that state-dependent pricing rules are unimportant Even if price changesacross product categories follow a prescheduled weekly time ta-ble the prices of which products to change is likely to be a state-dependent decision For example it could depend on changes insupply and demand conditions such as competitorsrsquo price changedecisions Indeed Levy Dutta and Bergen [1996] use retailstore-level orange juice price and cost data to demonstrate thatthe extent of price response to cost shocks that is the extent ofprice rigidity may depend on the nature of supply shocks37

We do not want to overstate the usefulness of our data fordirectly addressing the issue of monetary nonneutrality On onehand authors such as Caplin and Spulber [1987] have demon-strated that under certain conditions individual price rigiditymay not be sufcient for aggregate price rigidity but unfortu-nately our data do not speak directly to this issue38 On the otherhand authors such as Akerlof and Yellen [1985] Mankiw [1985]Parkin [1986] and Caplin and Leahy [1997] have shown that even

36 Danziger [1983] Caballero [1989] and Ball and Mankiw [1994] suggestthat time-dependent price adjustment of the type documented here can be optimalif the cost of gathering information about the state exceeds the cost of making theprice adjustment itself

37 We also considered the possibility of convexities in the cost of changingprices Our data do not suggest many convexities since the labor time spent inthe price tag change process the cost of printing and delivering price tags andin-store supervision time do not change with the size of a price change The onlymeasurable component of menu costs that could be convex is the cost of mistakesmade the larger the price change the higher the probability of a customer notic-ing the mistake and the larger the amount required to be refunded as compensa-tion Among the unmeasured components of menu cost the cost of corporatemanagerial time may increase with the size of a price change because larger pricechanges may require more serious consideration

38 Also see Balke and Wynne [1996] and Bryan and Cecchetti [1996] Sincewe do not have measures of how menu costs change over time our data also havelittle to say about time variation in menu costs or about the relationship betweenmenu costs and ination which during the period of the data collection (1991ndash1992) averaged about 3 percent annually

small menu costs can be relevant since they may be sufcient togenerate substantial aggregate nominal rigidity and thus largebusiness cycles Therefore as Blinder [1994] Kashyap [1995]and Slade [1996a] emphasize it is important to search for directevidence that such costs are indeed present at the micro level Bydirectly identifying documenting and measuring the magnitudeof menu costs at the store level we are taking an important stepin that direction

VI CONCLUSION AND FUTURE RESEARCH

Our main contribution is that we provide direct microeco-nomic evidence on the actual magnitude of menu costs for fourlarge U S retail supermarket chains The annual menu costs perstore at these chains average $105887 comprising 070 percentof revenues 352 percent of net prot margins and $052 perprice change on average

Further we provide evidence which suggests that thesemenu costs may be forming a barrier to price changes Specifi-cally we show that (1) supermarket chains not subject to itempricing law change prices two and a half times more frequentlythan the chain that is subject to the law (2) within the chain thatis subject to the item pricing law they change prices over threetimes as frequently for products that are exempt from this lawthan for the products which are subject to this law and (3) wend that these chains do not adjust prices of up to one-third ofthe products for which they face cost increases because of menucost considerations

When we relate these ndings to the existing theoreticalmodels of menu costs we conclude that the magnitude of menucosts we nd is large enough to be capable of having macroeco-nomic signicance Specically when considered in the context ofthe theoretical menu cost models of Blanchard and Kiyotaki[1987] and Ball and Romer [1990] we nd that the menu costgures we report are ldquonontrivialrdquo and their relative magnitudescross the minimum theoretical threshold needed to form a barrierto price adjustments

Despite the high relative magnitude of the marginal cost ofchanging price that we found the data still indicate frequentweekly price changes This is because of the high marginal bene-t of changing price which is due to the erce competition foundin the retail supermarket industry That marginal benets may

THE MAGNITUDE OF MENU COSTS 821

outweigh the marginal costs of changing prices in this industryhowever does not rule out the possibility that menu costs of themagnitude we nd here can create substantial nominal rigidityin other industries or markets In less competitive industries andmarkets menu costs of the type and magnitude we documenthere are likely to have a bigger impact on the frequency of priceadjustment and consequently on the degree of price rigidity

At a minimum the direct dollar measures of menu costs wereport here can be used as a starting point for future research onmeasuring their magnitude in other industries and establish-ments We anticipate that these menu costs will be similar inother markets which rely on posted prices (such as drugstoresdepartment stores etc) because the steps involved in the pricechange process are likely to be similar What may differ are thefrequency of price changes and the labor wage rates at thesestores For example since supermarket chains change thousandsof prices each week the total annual menu costs incurred bythese chains per store are likely to be high in comparison to otherretail formats such as chain drugstores or department storesThere are however a variety of industries for which the stepsinvolved in changing prices would be signicantly different fromthose reported in our study For example business-to-businesssales which often rely on a sales force will require changes in thelist price sheets changes in the instructions to the sales forcewhich may include education and discussion with the salespeoplein the company and so forth These business-to-business pricesalso often have more complex pricing schemes including quantitydiscounts bundling and individually negotiated prices As an-other example the composition of the cost of changing the news-stand prices of magazines [Cecchetti 1986] or the prices ofproducts sold through catalogs [Kashyap 1995] are different frommany of the menu cost components we discuss here Further thending that a centralization of pricing decisions makes the store-level managerial component of menu cost relatively small sug-gests that the managerial menu costs likely are highest insettings where price change decisions are decentralized Thus fu-ture empirical work should look at menu cost and its compositionin a variety of other industries markets and products with bothcentralized as well as decentralized price change decisions in or-der to see whether the magnitude of these costs can be general-ized and benchmarks can be established Further there aretechnological changes taking place in this and other industries

that promise to alter the structure of menu costs which deserveattention At the theoretical level our ndings suggest that it maybe worthwhile to explore models which incorporate the idea ofitem pricing laws as an additional component of menu costs

THE MAGNITUDE OF MENU COSTS 825

$200ndash$300 per price change reported by Slade [1996a] Thereare several possible reasons for this (1) our menu cost gures arebased on actual measurements of the resources that go into theprice change process whereas she estimates menu costs econo-metrically as model coefcients using a mix of store-level priceand aggregate cost data (2) we cover 25000 products that thesupermarkets carry rather than a single product category (3) ourmenu cost gures do not include all components of menu costsand (4) there could be differences in wage rates that may be im-portant given the signicance of the labor cost component inmenu costs

V2 The Effect of Menu Costs on the Price Change Activity of theSupermarkets

In this section we present evidence which suggests that thesemenu costs may be forming a barrier to price change activity Tobegin with consider the effect of the item pricing law on the pricechange activity of Chain E The data on the weekly frequency ofprice changes in each chain are displayed in the last two rows ofTable I According to these gures the average weekly frequencyof price changes in Chain E is only 1578 Thus on average ChainE changes the prices of only 631 percent of its products eachweek In contrast the average weekly frequency of price changesat Chains AndashD ranges from 3223 to 4316 for the four-chain aver-age of 3916 price changes weekly So Chains AndashD change priceson 1289 to 1726 percent of their products each week yielding afour-chain average of 1566 percent Thus Chain E which facesthe item pricing law changes prices only about one-third timesas frequently as do Chains AndashD30

Moreover within Chain E there are 400 products that areexempt from the item pricing law and thereby face lower menucosts We nd that there are an average of 83 weekly pricechanges for these products yielding 21 percent of these productschanging prices So within Chain E they change prices over threetimes as frequently for products with lower menu costs than for

roughly equals one-half of their target net prot per item which seemssubstantial

30 However note that our comparison of the two types of chains may not becompletely ceteris paribus because these stores are located in different states andtherefore there may be other chain-specic factors (in addition to item pricinglaws) that distinguish these stores We do not have any specic information onthese differences We do know however that the stores in these chains are similarin size and carry similar sets of products

QUARTERLY JOURNAL OF ECONOMICS814

the products with higher menu costs Note that this nding is onthe price change activity within the same chain offering almost anatural experiment on the impact of menu costs on the chainrsquospricing behavior Hence we provide evidence both across chainsas well as across products within a chain that as the costs ofchanging price go up the frequency of price changes goes downThus the menu costs we nd are signicant enough to affect thechainrsquos price change practice

We also have additional evidence from Chains A B and Dabout these menu costs being a barrier to certain price changesand it is summarized in Table V According to the Price Manage-ment Department of Chain A the chain experiences cost in-creases on 860 products in an average week to which it wouldlike to react with a price increase31 However on average 22 per-cent of these price increases are not implemented immediatelybecause the cost of changing prices for these products is too highto make it economically worthwhile Figures of the same magni-tude were reported by other chains For example Chain D experi-ences cost increases for 961 products in an average week Out ofthese the chain adjusts prices of only 633 products The re-maining 34 percent of the prices are left unadjusted because ofthe menu costs Similarly Chain B nds it economically ineffi-cient to adjust prices of 508 ie 30 percent of its products eachweek because of menu costs This provides additional evidencethat the menu costs incurred by these chains are preventing priceadjustments to some costs changes leading to price rigidities ofthe products involved32 Note that although we do not have simi-lar data for Chain E we would expect signicantly lower num-bers on this measure at that chain These gures also suggest anupper bound on the benet of complete price exibility under thecurrent pricing practice of weekly price adjustments Howeverif new technologies (eg ESL systems) and new pricing prac-tices (eg a decentralization of the price change decisions) are

31 Our data contain information only on the frequency of cost increasesAlthough it is more than likely that the supermarkets are experiencing cost de-creases as well our data set contained no information on such decreases

32 Menu costs may even be playing a role in the observed movement towardpricing strategies that rely on fewer price changes such as EDLP [Blattberg andNeslin 1989 Lattin and Ortmeyer 1991 Marketing News April 13 1992 p 8]According to Progressive Grocer [November 1992 p 50] ldquoA growing number ofoperators say they have switched from high-low pricing [to EDLP] They cite theinefciencies of making frequent price changes rdquo Similarly Hoch Dreze andPurk [1994 p 16] state that EDLP lowers operating costs by lowering ldquo in-store labor costs because of less frequent changeovers in special displaysrdquo

adopted allowing a fundamental change in the way the pricingmechanism is currently set the managers could consider morefrequent price change activity (eg multiple times each week) asmenu costs go down

In this paper we measure the menu costs at the chainsrsquo cur-rent level of price change activity It may be worthwhile to specu-late on the shape of the cost function relating menu costs to thefrequency of price changes by assessing how these costs wouldchange if the price change activity were to increase or to decreaseIt seems likely that many of the costs we report in this paper will(approximately) change linearly with additional price changeswithin the current range of price changes the chains are under-taking (plus or minus perhaps a thousand per week) For ex-ample the labor costs associated with changing a shelf price tagcosts of verifying price changes and the costs of mistakes oc-curring during this process all increase linearly with the fre-quency of price changes This is because most of the time-consuming steps involved in the price change process must berepeated each time an additional shelf price tag is changed (seeTable II) Further we were unable to nd many tasks that gener-ated signicant returns to scale It is unclear what cost savingsare available if the price change activity drops substantially be-

low the levels it is at now Clearly if price changes were nearzero or done less frequently than weekly (say monthly) therecould be major differences in these costs

What is less clear is how these costs would change at moreextreme levels of price change activity With less frequent pricechanges the menu costs could probably be reduced signicantlyalthough the cost of deciding what prices to set initially and thecost of putting the initial shelf price tags would still remain as alower bound of the menu cost However for achieving more priceexibility by changing prices more frequently (ie multiple timeseach week) substantial changes must be undertaken At presentthe supermarket chains are set up to make the majority of theirprice changes on a weekly basis with the appropriate systems inplace to make this process most efcient For example in orderto save costs and to have higher quality price tags (eg withcolor more details greater clarity glossy etc) the chains oftensend new price tag requests to a printing shop which takes threedays to print and deliver the labels to each store Then giventhe large number of price changes taking place and the goals ofminimizing customer disruptions and labor costs (such as over-time pay) and coordinating with advertised price promotions theprices are changed in the store over a two-to-three-day period (seeTable VI) The combination of these schedule and built-in lags isacceptable under the current practice of changing prices weeklybut would have to be adjusted dramatically to allow for signifi-cantly more frequent price changes on a regular basis

Perhaps even more imposing are the costs of changing themanagerial costs associated with the current weekly system ofprice changes The process of pricing at this organizational levelis not a self-contained activity taking place in isolation from otheroperations of the supermarket management Rather it is a partof a larger system of business decisions and operations The cur-rent process of operations (such as data collection and theiranalysis management meetings coordination of the decisionsacross functional areas etc) is set up to function on a weeklybasis33 Further these management accounting and logisticssystems are currently built around a tremendous amount of in-

35 If the supermarket chains indeed restructure the entire price change pro-cess and begin to change prices much more frequently (say two-to-three times aweek) on a regular basis then the shape of this cost function could change in anunpredictable way

V3 Relating Our Findings to the Existing Theoretical Models ofMenu Costs

In order to assess the magnitude of these menu cost guresin the context of the existing theoretical menu cost literatureconsider the following calculation experiments done within theframework of two theoretical menu cost models Blanchard andKiyotaki [1987] study a general equilibrium menu cost modelwith monopolistic competition and with unit elasticity of aggre-gate demand with respect to real money balances According totheir calculations menu costs of the magnitude of 008 percent ofrevenues which they consider ldquovery smallrdquo may be sufcient toprevent adjustment of prices Ball and Romer [1990] conductsimilar calculations in the framework of a model with imperfectcompetition and menu costs They nd that for plausible markupand labor elasticity parameter values menu costs needed to pre-vent price adjustment are 070 percent of revenues which as theysuggest are nonnegligible For smaller menu costs eg 004 per-cent of the revenue which Ball and Romer consider ldquotrivialrdquo im-plausibly large values of markup and labor elasticity parametersare needed to prevent price adjustment to monetary shocks

According to the gures in Table IV the reported menu costto revenues ratio for Chains AndashD averages 070 percent rangingfrom 061 percent to 076 percent These are signicantly largerthan the ldquotrivialrdquo 004 or 008 percent gures mentioned abovesuggesting that the menu cost gures we nd here are nontrivialFurther under the model and parameter values considered byBlanchard and Kiyotaki [1987] the menu cost gures we nd arehigher than the theoretical minimum needed to form a barrier toprice adjustments Under the model and parameter values con-sidered by Ball and Romer [1990] the reported menu costreve-nue ratio for all but one chain reaches or crosses the theoreticalthreshold of 070 needed to form a barrier to price adjustmentsThe existence of numerous unmeasured menu cost componentsdiscussed in subsection III5 also raises the possibility that theactual menu costs incurred by these chains are signicantlyhigher than that threshold This suggests that the menu costs wereport may be large enough to form a barrier to nominal priceadjustments when interpreted in the context of these models

An issue of interest in this literature is time-dependent ver-sus state-dependent pricing rules (see for example Caplin andLeahy [1991]) The evidence from our data set on the timing of

THE MAGNITUDE OF MENU COSTS 819

price changes suggests that the price change decisions in thesesupermarkets have a strong time-dependent price-setting ele-ment36 For example according to Table VI the prices in Chain Aare changed weekly according to the following schedule the pricechanges of general merchandise that is advertised is done Satur-day nights grocery and produce prices are changed Sundaynights the rest of the general merchandise prices are changed onMonday nights and the prices of advertised grocery items arechanged on Tuesday nights Thus as the gures in Table VI indi-cate over 96 percent of the price changes are done during Sundayand Monday nights However this does not imply that state-dependent pricing rules are unimportant Even if price changesacross product categories follow a prescheduled weekly time ta-ble the prices of which products to change is likely to be a state-dependent decision For example it could depend on changes insupply and demand conditions such as competitorsrsquo price changedecisions Indeed Levy Dutta and Bergen [1996] use retailstore-level orange juice price and cost data to demonstrate thatthe extent of price response to cost shocks that is the extent ofprice rigidity may depend on the nature of supply shocks37

We do not want to overstate the usefulness of our data fordirectly addressing the issue of monetary nonneutrality On onehand authors such as Caplin and Spulber [1987] have demon-strated that under certain conditions individual price rigiditymay not be sufcient for aggregate price rigidity but unfortu-nately our data do not speak directly to this issue38 On the otherhand authors such as Akerlof and Yellen [1985] Mankiw [1985]Parkin [1986] and Caplin and Leahy [1997] have shown that even

36 Danziger [1983] Caballero [1989] and Ball and Mankiw [1994] suggestthat time-dependent price adjustment of the type documented here can be optimalif the cost of gathering information about the state exceeds the cost of making theprice adjustment itself

37 We also considered the possibility of convexities in the cost of changingprices Our data do not suggest many convexities since the labor time spent inthe price tag change process the cost of printing and delivering price tags andin-store supervision time do not change with the size of a price change The onlymeasurable component of menu costs that could be convex is the cost of mistakesmade the larger the price change the higher the probability of a customer notic-ing the mistake and the larger the amount required to be refunded as compensa-tion Among the unmeasured components of menu cost the cost of corporatemanagerial time may increase with the size of a price change because larger pricechanges may require more serious consideration

38 Also see Balke and Wynne [1996] and Bryan and Cecchetti [1996] Sincewe do not have measures of how menu costs change over time our data also havelittle to say about time variation in menu costs or about the relationship betweenmenu costs and ination which during the period of the data collection (1991ndash1992) averaged about 3 percent annually

QUARTERLY JOURNAL OF ECONOMICS820

small menu costs can be relevant since they may be sufcient togenerate substantial aggregate nominal rigidity and thus largebusiness cycles Therefore as Blinder [1994] Kashyap [1995]and Slade [1996a] emphasize it is important to search for directevidence that such costs are indeed present at the micro level Bydirectly identifying documenting and measuring the magnitudeof menu costs at the store level we are taking an important stepin that direction

VI CONCLUSION AND FUTURE RESEARCH

Our main contribution is that we provide direct microeco-nomic evidence on the actual magnitude of menu costs for fourlarge U S retail supermarket chains The annual menu costs perstore at these chains average $105887 comprising 070 percentof revenues 352 percent of net prot margins and $052 perprice change on average

Further we provide evidence which suggests that thesemenu costs may be forming a barrier to price changes Specifi-cally we show that (1) supermarket chains not subject to itempricing law change prices two and a half times more frequentlythan the chain that is subject to the law (2) within the chain thatis subject to the item pricing law they change prices over threetimes as frequently for products that are exempt from this lawthan for the products which are subject to this law and (3) wend that these chains do not adjust prices of up to one-third ofthe products for which they face cost increases because of menucost considerations

When we relate these ndings to the existing theoreticalmodels of menu costs we conclude that the magnitude of menucosts we nd is large enough to be capable of having macroeco-nomic signicance Specically when considered in the context ofthe theoretical menu cost models of Blanchard and Kiyotaki[1987] and Ball and Romer [1990] we nd that the menu costgures we report are ldquonontrivialrdquo and their relative magnitudescross the minimum theoretical threshold needed to form a barrierto price adjustments

Despite the high relative magnitude of the marginal cost ofchanging price that we found the data still indicate frequentweekly price changes This is because of the high marginal bene-t of changing price which is due to the erce competition foundin the retail supermarket industry That marginal benets may

the products with higher menu costs Note that this nding is onthe price change activity within the same chain offering almost anatural experiment on the impact of menu costs on the chainrsquospricing behavior Hence we provide evidence both across chainsas well as across products within a chain that as the costs ofchanging price go up the frequency of price changes goes downThus the menu costs we nd are signicant enough to affect thechainrsquos price change practice

We also have additional evidence from Chains A B and Dabout these menu costs being a barrier to certain price changesand it is summarized in Table V According to the Price Manage-ment Department of Chain A the chain experiences cost in-creases on 860 products in an average week to which it wouldlike to react with a price increase31 However on average 22 per-cent of these price increases are not implemented immediatelybecause the cost of changing prices for these products is too highto make it economically worthwhile Figures of the same magni-tude were reported by other chains For example Chain D experi-ences cost increases for 961 products in an average week Out ofthese the chain adjusts prices of only 633 products The re-maining 34 percent of the prices are left unadjusted because ofthe menu costs Similarly Chain B nds it economically ineffi-cient to adjust prices of 508 ie 30 percent of its products eachweek because of menu costs This provides additional evidencethat the menu costs incurred by these chains are preventing priceadjustments to some costs changes leading to price rigidities ofthe products involved32 Note that although we do not have simi-lar data for Chain E we would expect signicantly lower num-bers on this measure at that chain These gures also suggest anupper bound on the benet of complete price exibility under thecurrent pricing practice of weekly price adjustments Howeverif new technologies (eg ESL systems) and new pricing prac-tices (eg a decentralization of the price change decisions) are

31 Our data contain information only on the frequency of cost increasesAlthough it is more than likely that the supermarkets are experiencing cost de-creases as well our data set contained no information on such decreases

32 Menu costs may even be playing a role in the observed movement towardpricing strategies that rely on fewer price changes such as EDLP [Blattberg andNeslin 1989 Lattin and Ortmeyer 1991 Marketing News April 13 1992 p 8]According to Progressive Grocer [November 1992 p 50] ldquoA growing number ofoperators say they have switched from high-low pricing [to EDLP] They cite theinefciencies of making frequent price changes rdquo Similarly Hoch Dreze andPurk [1994 p 16] state that EDLP lowers operating costs by lowering ldquo in-store labor costs because of less frequent changeovers in special displaysrdquo

adopted allowing a fundamental change in the way the pricingmechanism is currently set the managers could consider morefrequent price change activity (eg multiple times each week) asmenu costs go down

In this paper we measure the menu costs at the chainsrsquo cur-rent level of price change activity It may be worthwhile to specu-late on the shape of the cost function relating menu costs to thefrequency of price changes by assessing how these costs wouldchange if the price change activity were to increase or to decreaseIt seems likely that many of the costs we report in this paper will(approximately) change linearly with additional price changeswithin the current range of price changes the chains are under-taking (plus or minus perhaps a thousand per week) For ex-ample the labor costs associated with changing a shelf price tagcosts of verifying price changes and the costs of mistakes oc-curring during this process all increase linearly with the fre-quency of price changes This is because most of the time-consuming steps involved in the price change process must berepeated each time an additional shelf price tag is changed (seeTable II) Further we were unable to nd many tasks that gener-ated signicant returns to scale It is unclear what cost savingsare available if the price change activity drops substantially be-

low the levels it is at now Clearly if price changes were nearzero or done less frequently than weekly (say monthly) therecould be major differences in these costs

What is less clear is how these costs would change at moreextreme levels of price change activity With less frequent pricechanges the menu costs could probably be reduced signicantlyalthough the cost of deciding what prices to set initially and thecost of putting the initial shelf price tags would still remain as alower bound of the menu cost However for achieving more priceexibility by changing prices more frequently (ie multiple timeseach week) substantial changes must be undertaken At presentthe supermarket chains are set up to make the majority of theirprice changes on a weekly basis with the appropriate systems inplace to make this process most efcient For example in orderto save costs and to have higher quality price tags (eg withcolor more details greater clarity glossy etc) the chains oftensend new price tag requests to a printing shop which takes threedays to print and deliver the labels to each store Then giventhe large number of price changes taking place and the goals ofminimizing customer disruptions and labor costs (such as over-time pay) and coordinating with advertised price promotions theprices are changed in the store over a two-to-three-day period (seeTable VI) The combination of these schedule and built-in lags isacceptable under the current practice of changing prices weeklybut would have to be adjusted dramatically to allow for signifi-cantly more frequent price changes on a regular basis

Perhaps even more imposing are the costs of changing themanagerial costs associated with the current weekly system ofprice changes The process of pricing at this organizational levelis not a self-contained activity taking place in isolation from otheroperations of the supermarket management Rather it is a partof a larger system of business decisions and operations The cur-rent process of operations (such as data collection and theiranalysis management meetings coordination of the decisionsacross functional areas etc) is set up to function on a weeklybasis33 Further these management accounting and logisticssystems are currently built around a tremendous amount of in-

35 If the supermarket chains indeed restructure the entire price change pro-cess and begin to change prices much more frequently (say two-to-three times aweek) on a regular basis then the shape of this cost function could change in anunpredictable way

V3 Relating Our Findings to the Existing Theoretical Models ofMenu Costs

In order to assess the magnitude of these menu cost guresin the context of the existing theoretical menu cost literatureconsider the following calculation experiments done within theframework of two theoretical menu cost models Blanchard andKiyotaki [1987] study a general equilibrium menu cost modelwith monopolistic competition and with unit elasticity of aggre-gate demand with respect to real money balances According totheir calculations menu costs of the magnitude of 008 percent ofrevenues which they consider ldquovery smallrdquo may be sufcient toprevent adjustment of prices Ball and Romer [1990] conductsimilar calculations in the framework of a model with imperfectcompetition and menu costs They nd that for plausible markupand labor elasticity parameter values menu costs needed to pre-vent price adjustment are 070 percent of revenues which as theysuggest are nonnegligible For smaller menu costs eg 004 per-cent of the revenue which Ball and Romer consider ldquotrivialrdquo im-plausibly large values of markup and labor elasticity parametersare needed to prevent price adjustment to monetary shocks

According to the gures in Table IV the reported menu costto revenues ratio for Chains AndashD averages 070 percent rangingfrom 061 percent to 076 percent These are signicantly largerthan the ldquotrivialrdquo 004 or 008 percent gures mentioned abovesuggesting that the menu cost gures we nd here are nontrivialFurther under the model and parameter values considered byBlanchard and Kiyotaki [1987] the menu cost gures we nd arehigher than the theoretical minimum needed to form a barrier toprice adjustments Under the model and parameter values con-sidered by Ball and Romer [1990] the reported menu costreve-nue ratio for all but one chain reaches or crosses the theoreticalthreshold of 070 needed to form a barrier to price adjustmentsThe existence of numerous unmeasured menu cost componentsdiscussed in subsection III5 also raises the possibility that theactual menu costs incurred by these chains are signicantlyhigher than that threshold This suggests that the menu costs wereport may be large enough to form a barrier to nominal priceadjustments when interpreted in the context of these models

An issue of interest in this literature is time-dependent ver-sus state-dependent pricing rules (see for example Caplin andLeahy [1991]) The evidence from our data set on the timing of

THE MAGNITUDE OF MENU COSTS 819

price changes suggests that the price change decisions in thesesupermarkets have a strong time-dependent price-setting ele-ment36 For example according to Table VI the prices in Chain Aare changed weekly according to the following schedule the pricechanges of general merchandise that is advertised is done Satur-day nights grocery and produce prices are changed Sundaynights the rest of the general merchandise prices are changed onMonday nights and the prices of advertised grocery items arechanged on Tuesday nights Thus as the gures in Table VI indi-cate over 96 percent of the price changes are done during Sundayand Monday nights However this does not imply that state-dependent pricing rules are unimportant Even if price changesacross product categories follow a prescheduled weekly time ta-ble the prices of which products to change is likely to be a state-dependent decision For example it could depend on changes insupply and demand conditions such as competitorsrsquo price changedecisions Indeed Levy Dutta and Bergen [1996] use retailstore-level orange juice price and cost data to demonstrate thatthe extent of price response to cost shocks that is the extent ofprice rigidity may depend on the nature of supply shocks37

We do not want to overstate the usefulness of our data fordirectly addressing the issue of monetary nonneutrality On onehand authors such as Caplin and Spulber [1987] have demon-strated that under certain conditions individual price rigiditymay not be sufcient for aggregate price rigidity but unfortu-nately our data do not speak directly to this issue38 On the otherhand authors such as Akerlof and Yellen [1985] Mankiw [1985]Parkin [1986] and Caplin and Leahy [1997] have shown that even

36 Danziger [1983] Caballero [1989] and Ball and Mankiw [1994] suggestthat time-dependent price adjustment of the type documented here can be optimalif the cost of gathering information about the state exceeds the cost of making theprice adjustment itself

37 We also considered the possibility of convexities in the cost of changingprices Our data do not suggest many convexities since the labor time spent inthe price tag change process the cost of printing and delivering price tags andin-store supervision time do not change with the size of a price change The onlymeasurable component of menu costs that could be convex is the cost of mistakesmade the larger the price change the higher the probability of a customer notic-ing the mistake and the larger the amount required to be refunded as compensa-tion Among the unmeasured components of menu cost the cost of corporatemanagerial time may increase with the size of a price change because larger pricechanges may require more serious consideration

38 Also see Balke and Wynne [1996] and Bryan and Cecchetti [1996] Sincewe do not have measures of how menu costs change over time our data also havelittle to say about time variation in menu costs or about the relationship betweenmenu costs and ination which during the period of the data collection (1991ndash1992) averaged about 3 percent annually

QUARTERLY JOURNAL OF ECONOMICS820

small menu costs can be relevant since they may be sufcient togenerate substantial aggregate nominal rigidity and thus largebusiness cycles Therefore as Blinder [1994] Kashyap [1995]and Slade [1996a] emphasize it is important to search for directevidence that such costs are indeed present at the micro level Bydirectly identifying documenting and measuring the magnitudeof menu costs at the store level we are taking an important stepin that direction

VI CONCLUSION AND FUTURE RESEARCH

Our main contribution is that we provide direct microeco-nomic evidence on the actual magnitude of menu costs for fourlarge U S retail supermarket chains The annual menu costs perstore at these chains average $105887 comprising 070 percentof revenues 352 percent of net prot margins and $052 perprice change on average

Further we provide evidence which suggests that thesemenu costs may be forming a barrier to price changes Specifi-cally we show that (1) supermarket chains not subject to itempricing law change prices two and a half times more frequentlythan the chain that is subject to the law (2) within the chain thatis subject to the item pricing law they change prices over threetimes as frequently for products that are exempt from this lawthan for the products which are subject to this law and (3) wend that these chains do not adjust prices of up to one-third ofthe products for which they face cost increases because of menucost considerations

When we relate these ndings to the existing theoreticalmodels of menu costs we conclude that the magnitude of menucosts we nd is large enough to be capable of having macroeco-nomic signicance Specically when considered in the context ofthe theoretical menu cost models of Blanchard and Kiyotaki[1987] and Ball and Romer [1990] we nd that the menu costgures we report are ldquonontrivialrdquo and their relative magnitudescross the minimum theoretical threshold needed to form a barrierto price adjustments

Despite the high relative magnitude of the marginal cost ofchanging price that we found the data still indicate frequentweekly price changes This is because of the high marginal bene-t of changing price which is due to the erce competition foundin the retail supermarket industry That marginal benets may

In this paper we measure the menu costs at the chainsrsquo cur-rent level of price change activity It may be worthwhile to specu-late on the shape of the cost function relating menu costs to thefrequency of price changes by assessing how these costs wouldchange if the price change activity were to increase or to decreaseIt seems likely that many of the costs we report in this paper will(approximately) change linearly with additional price changeswithin the current range of price changes the chains are under-taking (plus or minus perhaps a thousand per week) For ex-ample the labor costs associated with changing a shelf price tagcosts of verifying price changes and the costs of mistakes oc-curring during this process all increase linearly with the fre-quency of price changes This is because most of the time-consuming steps involved in the price change process must berepeated each time an additional shelf price tag is changed (seeTable II) Further we were unable to nd many tasks that gener-ated signicant returns to scale It is unclear what cost savingsare available if the price change activity drops substantially be-

low the levels it is at now Clearly if price changes were nearzero or done less frequently than weekly (say monthly) therecould be major differences in these costs

What is less clear is how these costs would change at moreextreme levels of price change activity With less frequent pricechanges the menu costs could probably be reduced signicantlyalthough the cost of deciding what prices to set initially and thecost of putting the initial shelf price tags would still remain as alower bound of the menu cost However for achieving more priceexibility by changing prices more frequently (ie multiple timeseach week) substantial changes must be undertaken At presentthe supermarket chains are set up to make the majority of theirprice changes on a weekly basis with the appropriate systems inplace to make this process most efcient For example in orderto save costs and to have higher quality price tags (eg withcolor more details greater clarity glossy etc) the chains oftensend new price tag requests to a printing shop which takes threedays to print and deliver the labels to each store Then giventhe large number of price changes taking place and the goals ofminimizing customer disruptions and labor costs (such as over-time pay) and coordinating with advertised price promotions theprices are changed in the store over a two-to-three-day period (seeTable VI) The combination of these schedule and built-in lags isacceptable under the current practice of changing prices weeklybut would have to be adjusted dramatically to allow for signifi-cantly more frequent price changes on a regular basis

Perhaps even more imposing are the costs of changing themanagerial costs associated with the current weekly system ofprice changes The process of pricing at this organizational levelis not a self-contained activity taking place in isolation from otheroperations of the supermarket management Rather it is a partof a larger system of business decisions and operations The cur-rent process of operations (such as data collection and theiranalysis management meetings coordination of the decisionsacross functional areas etc) is set up to function on a weeklybasis33 Further these management accounting and logisticssystems are currently built around a tremendous amount of in-

V3 Relating Our Findings to the Existing Theoretical Models ofMenu Costs

In order to assess the magnitude of these menu cost guresin the context of the existing theoretical menu cost literatureconsider the following calculation experiments done within theframework of two theoretical menu cost models Blanchard andKiyotaki [1987] study a general equilibrium menu cost modelwith monopolistic competition and with unit elasticity of aggre-gate demand with respect to real money balances According totheir calculations menu costs of the magnitude of 008 percent ofrevenues which they consider ldquovery smallrdquo may be sufcient toprevent adjustment of prices Ball and Romer [1990] conductsimilar calculations in the framework of a model with imperfectcompetition and menu costs They nd that for plausible markupand labor elasticity parameter values menu costs needed to pre-vent price adjustment are 070 percent of revenues which as theysuggest are nonnegligible For smaller menu costs eg 004 per-cent of the revenue which Ball and Romer consider ldquotrivialrdquo im-plausibly large values of markup and labor elasticity parametersare needed to prevent price adjustment to monetary shocks

According to the gures in Table IV the reported menu costto revenues ratio for Chains AndashD averages 070 percent rangingfrom 061 percent to 076 percent These are signicantly largerthan the ldquotrivialrdquo 004 or 008 percent gures mentioned abovesuggesting that the menu cost gures we nd here are nontrivialFurther under the model and parameter values considered byBlanchard and Kiyotaki [1987] the menu cost gures we nd arehigher than the theoretical minimum needed to form a barrier toprice adjustments Under the model and parameter values con-sidered by Ball and Romer [1990] the reported menu costreve-nue ratio for all but one chain reaches or crosses the theoreticalthreshold of 070 needed to form a barrier to price adjustmentsThe existence of numerous unmeasured menu cost componentsdiscussed in subsection III5 also raises the possibility that theactual menu costs incurred by these chains are signicantlyhigher than that threshold This suggests that the menu costs wereport may be large enough to form a barrier to nominal priceadjustments when interpreted in the context of these models

An issue of interest in this literature is time-dependent ver-sus state-dependent pricing rules (see for example Caplin andLeahy [1991]) The evidence from our data set on the timing of

THE MAGNITUDE OF MENU COSTS 819

price changes suggests that the price change decisions in thesesupermarkets have a strong time-dependent price-setting ele-ment36 For example according to Table VI the prices in Chain Aare changed weekly according to the following schedule the pricechanges of general merchandise that is advertised is done Satur-day nights grocery and produce prices are changed Sundaynights the rest of the general merchandise prices are changed onMonday nights and the prices of advertised grocery items arechanged on Tuesday nights Thus as the gures in Table VI indi-cate over 96 percent of the price changes are done during Sundayand Monday nights However this does not imply that state-dependent pricing rules are unimportant Even if price changesacross product categories follow a prescheduled weekly time ta-ble the prices of which products to change is likely to be a state-dependent decision For example it could depend on changes insupply and demand conditions such as competitorsrsquo price changedecisions Indeed Levy Dutta and Bergen [1996] use retailstore-level orange juice price and cost data to demonstrate thatthe extent of price response to cost shocks that is the extent ofprice rigidity may depend on the nature of supply shocks37

We do not want to overstate the usefulness of our data fordirectly addressing the issue of monetary nonneutrality On onehand authors such as Caplin and Spulber [1987] have demon-strated that under certain conditions individual price rigiditymay not be sufcient for aggregate price rigidity but unfortu-nately our data do not speak directly to this issue38 On the otherhand authors such as Akerlof and Yellen [1985] Mankiw [1985]Parkin [1986] and Caplin and Leahy [1997] have shown that even

36 Danziger [1983] Caballero [1989] and Ball and Mankiw [1994] suggestthat time-dependent price adjustment of the type documented here can be optimalif the cost of gathering information about the state exceeds the cost of making theprice adjustment itself

37 We also considered the possibility of convexities in the cost of changingprices Our data do not suggest many convexities since the labor time spent inthe price tag change process the cost of printing and delivering price tags andin-store supervision time do not change with the size of a price change The onlymeasurable component of menu costs that could be convex is the cost of mistakesmade the larger the price change the higher the probability of a customer notic-ing the mistake and the larger the amount required to be refunded as compensa-tion Among the unmeasured components of menu cost the cost of corporatemanagerial time may increase with the size of a price change because larger pricechanges may require more serious consideration

38 Also see Balke and Wynne [1996] and Bryan and Cecchetti [1996] Sincewe do not have measures of how menu costs change over time our data also havelittle to say about time variation in menu costs or about the relationship betweenmenu costs and ination which during the period of the data collection (1991ndash1992) averaged about 3 percent annually

QUARTERLY JOURNAL OF ECONOMICS820

small menu costs can be relevant since they may be sufcient togenerate substantial aggregate nominal rigidity and thus largebusiness cycles Therefore as Blinder [1994] Kashyap [1995]and Slade [1996a] emphasize it is important to search for directevidence that such costs are indeed present at the micro level Bydirectly identifying documenting and measuring the magnitudeof menu costs at the store level we are taking an important stepin that direction

VI CONCLUSION AND FUTURE RESEARCH

Our main contribution is that we provide direct microeco-nomic evidence on the actual magnitude of menu costs for fourlarge U S retail supermarket chains The annual menu costs perstore at these chains average $105887 comprising 070 percentof revenues 352 percent of net prot margins and $052 perprice change on average

Further we provide evidence which suggests that thesemenu costs may be forming a barrier to price changes Specifi-cally we show that (1) supermarket chains not subject to itempricing law change prices two and a half times more frequentlythan the chain that is subject to the law (2) within the chain thatis subject to the item pricing law they change prices over threetimes as frequently for products that are exempt from this lawthan for the products which are subject to this law and (3) wend that these chains do not adjust prices of up to one-third ofthe products for which they face cost increases because of menucost considerations

When we relate these ndings to the existing theoreticalmodels of menu costs we conclude that the magnitude of menucosts we nd is large enough to be capable of having macroeco-nomic signicance Specically when considered in the context ofthe theoretical menu cost models of Blanchard and Kiyotaki[1987] and Ball and Romer [1990] we nd that the menu costgures we report are ldquonontrivialrdquo and their relative magnitudescross the minimum theoretical threshold needed to form a barrierto price adjustments

Despite the high relative magnitude of the marginal cost ofchanging price that we found the data still indicate frequentweekly price changes This is because of the high marginal bene-t of changing price which is due to the erce competition foundin the retail supermarket industry That marginal benets may

THE MAGNITUDE OF MENU COSTS 821

outweigh the marginal costs of changing prices in this industryhowever does not rule out the possibility that menu costs of themagnitude we nd here can create substantial nominal rigidityin other industries or markets In less competitive industries andmarkets menu costs of the type and magnitude we documenthere are likely to have a bigger impact on the frequency of priceadjustment and consequently on the degree of price rigidity

At a minimum the direct dollar measures of menu costs wereport here can be used as a starting point for future research onmeasuring their magnitude in other industries and establish-ments We anticipate that these menu costs will be similar inother markets which rely on posted prices (such as drugstoresdepartment stores etc) because the steps involved in the pricechange process are likely to be similar What may differ are thefrequency of price changes and the labor wage rates at thesestores For example since supermarket chains change thousandsof prices each week the total annual menu costs incurred bythese chains per store are likely to be high in comparison to otherretail formats such as chain drugstores or department storesThere are however a variety of industries for which the stepsinvolved in changing prices would be signicantly different fromthose reported in our study For example business-to-businesssales which often rely on a sales force will require changes in thelist price sheets changes in the instructions to the sales forcewhich may include education and discussion with the salespeoplein the company and so forth These business-to-business pricesalso often have more complex pricing schemes including quantitydiscounts bundling and individually negotiated prices As an-other example the composition of the cost of changing the news-stand prices of magazines [Cecchetti 1986] or the prices ofproducts sold through catalogs [Kashyap 1995] are different frommany of the menu cost components we discuss here Further thending that a centralization of pricing decisions makes the store-level managerial component of menu cost relatively small sug-gests that the managerial menu costs likely are highest insettings where price change decisions are decentralized Thus fu-ture empirical work should look at menu cost and its compositionin a variety of other industries markets and products with bothcentralized as well as decentralized price change decisions in or-der to see whether the magnitude of these costs can be general-ized and benchmarks can be established Further there aretechnological changes taking place in this and other industries

that promise to alter the structure of menu costs which deserveattention At the theoretical level our ndings suggest that it maybe worthwhile to explore models which incorporate the idea ofitem pricing laws as an additional component of menu costs

V3 Relating Our Findings to the Existing Theoretical Models ofMenu Costs

In order to assess the magnitude of these menu cost guresin the context of the existing theoretical menu cost literatureconsider the following calculation experiments done within theframework of two theoretical menu cost models Blanchard andKiyotaki [1987] study a general equilibrium menu cost modelwith monopolistic competition and with unit elasticity of aggre-gate demand with respect to real money balances According totheir calculations menu costs of the magnitude of 008 percent ofrevenues which they consider ldquovery smallrdquo may be sufcient toprevent adjustment of prices Ball and Romer [1990] conductsimilar calculations in the framework of a model with imperfectcompetition and menu costs They nd that for plausible markupand labor elasticity parameter values menu costs needed to pre-vent price adjustment are 070 percent of revenues which as theysuggest are nonnegligible For smaller menu costs eg 004 per-cent of the revenue which Ball and Romer consider ldquotrivialrdquo im-plausibly large values of markup and labor elasticity parametersare needed to prevent price adjustment to monetary shocks

According to the gures in Table IV the reported menu costto revenues ratio for Chains AndashD averages 070 percent rangingfrom 061 percent to 076 percent These are signicantly largerthan the ldquotrivialrdquo 004 or 008 percent gures mentioned abovesuggesting that the menu cost gures we nd here are nontrivialFurther under the model and parameter values considered byBlanchard and Kiyotaki [1987] the menu cost gures we nd arehigher than the theoretical minimum needed to form a barrier toprice adjustments Under the model and parameter values con-sidered by Ball and Romer [1990] the reported menu costreve-nue ratio for all but one chain reaches or crosses the theoreticalthreshold of 070 needed to form a barrier to price adjustmentsThe existence of numerous unmeasured menu cost componentsdiscussed in subsection III5 also raises the possibility that theactual menu costs incurred by these chains are signicantlyhigher than that threshold This suggests that the menu costs wereport may be large enough to form a barrier to nominal priceadjustments when interpreted in the context of these models

An issue of interest in this literature is time-dependent ver-sus state-dependent pricing rules (see for example Caplin andLeahy [1991]) The evidence from our data set on the timing of

THE MAGNITUDE OF MENU COSTS 819

price changes suggests that the price change decisions in thesesupermarkets have a strong time-dependent price-setting ele-ment36 For example according to Table VI the prices in Chain Aare changed weekly according to the following schedule the pricechanges of general merchandise that is advertised is done Satur-day nights grocery and produce prices are changed Sundaynights the rest of the general merchandise prices are changed onMonday nights and the prices of advertised grocery items arechanged on Tuesday nights Thus as the gures in Table VI indi-cate over 96 percent of the price changes are done during Sundayand Monday nights However this does not imply that state-dependent pricing rules are unimportant Even if price changesacross product categories follow a prescheduled weekly time ta-ble the prices of which products to change is likely to be a state-dependent decision For example it could depend on changes insupply and demand conditions such as competitorsrsquo price changedecisions Indeed Levy Dutta and Bergen [1996] use retailstore-level orange juice price and cost data to demonstrate thatthe extent of price response to cost shocks that is the extent ofprice rigidity may depend on the nature of supply shocks37

We do not want to overstate the usefulness of our data fordirectly addressing the issue of monetary nonneutrality On onehand authors such as Caplin and Spulber [1987] have demon-strated that under certain conditions individual price rigiditymay not be sufcient for aggregate price rigidity but unfortu-nately our data do not speak directly to this issue38 On the otherhand authors such as Akerlof and Yellen [1985] Mankiw [1985]Parkin [1986] and Caplin and Leahy [1997] have shown that even

36 Danziger [1983] Caballero [1989] and Ball and Mankiw [1994] suggestthat time-dependent price adjustment of the type documented here can be optimalif the cost of gathering information about the state exceeds the cost of making theprice adjustment itself

37 We also considered the possibility of convexities in the cost of changingprices Our data do not suggest many convexities since the labor time spent inthe price tag change process the cost of printing and delivering price tags andin-store supervision time do not change with the size of a price change The onlymeasurable component of menu costs that could be convex is the cost of mistakesmade the larger the price change the higher the probability of a customer notic-ing the mistake and the larger the amount required to be refunded as compensa-tion Among the unmeasured components of menu cost the cost of corporatemanagerial time may increase with the size of a price change because larger pricechanges may require more serious consideration

38 Also see Balke and Wynne [1996] and Bryan and Cecchetti [1996] Sincewe do not have measures of how menu costs change over time our data also havelittle to say about time variation in menu costs or about the relationship betweenmenu costs and ination which during the period of the data collection (1991ndash1992) averaged about 3 percent annually

QUARTERLY JOURNAL OF ECONOMICS820

small menu costs can be relevant since they may be sufcient togenerate substantial aggregate nominal rigidity and thus largebusiness cycles Therefore as Blinder [1994] Kashyap [1995]and Slade [1996a] emphasize it is important to search for directevidence that such costs are indeed present at the micro level Bydirectly identifying documenting and measuring the magnitudeof menu costs at the store level we are taking an important stepin that direction

VI CONCLUSION AND FUTURE RESEARCH

Our main contribution is that we provide direct microeco-nomic evidence on the actual magnitude of menu costs for fourlarge U S retail supermarket chains The annual menu costs perstore at these chains average $105887 comprising 070 percentof revenues 352 percent of net prot margins and $052 perprice change on average

Further we provide evidence which suggests that thesemenu costs may be forming a barrier to price changes Specifi-cally we show that (1) supermarket chains not subject to itempricing law change prices two and a half times more frequentlythan the chain that is subject to the law (2) within the chain thatis subject to the item pricing law they change prices over threetimes as frequently for products that are exempt from this lawthan for the products which are subject to this law and (3) wend that these chains do not adjust prices of up to one-third ofthe products for which they face cost increases because of menucost considerations

When we relate these ndings to the existing theoreticalmodels of menu costs we conclude that the magnitude of menucosts we nd is large enough to be capable of having macroeco-nomic signicance Specically when considered in the context ofthe theoretical menu cost models of Blanchard and Kiyotaki[1987] and Ball and Romer [1990] we nd that the menu costgures we report are ldquonontrivialrdquo and their relative magnitudescross the minimum theoretical threshold needed to form a barrierto price adjustments

Despite the high relative magnitude of the marginal cost ofchanging price that we found the data still indicate frequentweekly price changes This is because of the high marginal bene-t of changing price which is due to the erce competition foundin the retail supermarket industry That marginal benets may

THE MAGNITUDE OF MENU COSTS 821

outweigh the marginal costs of changing prices in this industryhowever does not rule out the possibility that menu costs of themagnitude we nd here can create substantial nominal rigidityin other industries or markets In less competitive industries andmarkets menu costs of the type and magnitude we documenthere are likely to have a bigger impact on the frequency of priceadjustment and consequently on the degree of price rigidity

At a minimum the direct dollar measures of menu costs wereport here can be used as a starting point for future research onmeasuring their magnitude in other industries and establish-ments We anticipate that these menu costs will be similar inother markets which rely on posted prices (such as drugstoresdepartment stores etc) because the steps involved in the pricechange process are likely to be similar What may differ are thefrequency of price changes and the labor wage rates at thesestores For example since supermarket chains change thousandsof prices each week the total annual menu costs incurred bythese chains per store are likely to be high in comparison to otherretail formats such as chain drugstores or department storesThere are however a variety of industries for which the stepsinvolved in changing prices would be signicantly different fromthose reported in our study For example business-to-businesssales which often rely on a sales force will require changes in thelist price sheets changes in the instructions to the sales forcewhich may include education and discussion with the salespeoplein the company and so forth These business-to-business pricesalso often have more complex pricing schemes including quantitydiscounts bundling and individually negotiated prices As an-other example the composition of the cost of changing the news-stand prices of magazines [Cecchetti 1986] or the prices ofproducts sold through catalogs [Kashyap 1995] are different frommany of the menu cost components we discuss here Further thending that a centralization of pricing decisions makes the store-level managerial component of menu cost relatively small sug-gests that the managerial menu costs likely are highest insettings where price change decisions are decentralized Thus fu-ture empirical work should look at menu cost and its compositionin a variety of other industries markets and products with bothcentralized as well as decentralized price change decisions in or-der to see whether the magnitude of these costs can be general-ized and benchmarks can be established Further there aretechnological changes taking place in this and other industries

that promise to alter the structure of menu costs which deserveattention At the theoretical level our ndings suggest that it maybe worthwhile to explore models which incorporate the idea ofitem pricing laws as an additional component of menu costs

V3 Relating Our Findings to the Existing Theoretical Models ofMenu Costs

In order to assess the magnitude of these menu cost guresin the context of the existing theoretical menu cost literatureconsider the following calculation experiments done within theframework of two theoretical menu cost models Blanchard andKiyotaki [1987] study a general equilibrium menu cost modelwith monopolistic competition and with unit elasticity of aggre-gate demand with respect to real money balances According totheir calculations menu costs of the magnitude of 008 percent ofrevenues which they consider ldquovery smallrdquo may be sufcient toprevent adjustment of prices Ball and Romer [1990] conductsimilar calculations in the framework of a model with imperfectcompetition and menu costs They nd that for plausible markupand labor elasticity parameter values menu costs needed to pre-vent price adjustment are 070 percent of revenues which as theysuggest are nonnegligible For smaller menu costs eg 004 per-cent of the revenue which Ball and Romer consider ldquotrivialrdquo im-plausibly large values of markup and labor elasticity parametersare needed to prevent price adjustment to monetary shocks

According to the gures in Table IV the reported menu costto revenues ratio for Chains AndashD averages 070 percent rangingfrom 061 percent to 076 percent These are signicantly largerthan the ldquotrivialrdquo 004 or 008 percent gures mentioned abovesuggesting that the menu cost gures we nd here are nontrivialFurther under the model and parameter values considered byBlanchard and Kiyotaki [1987] the menu cost gures we nd arehigher than the theoretical minimum needed to form a barrier toprice adjustments Under the model and parameter values con-sidered by Ball and Romer [1990] the reported menu costreve-nue ratio for all but one chain reaches or crosses the theoreticalthreshold of 070 needed to form a barrier to price adjustmentsThe existence of numerous unmeasured menu cost componentsdiscussed in subsection III5 also raises the possibility that theactual menu costs incurred by these chains are signicantlyhigher than that threshold This suggests that the menu costs wereport may be large enough to form a barrier to nominal priceadjustments when interpreted in the context of these models

An issue of interest in this literature is time-dependent ver-sus state-dependent pricing rules (see for example Caplin andLeahy [1991]) The evidence from our data set on the timing of

THE MAGNITUDE OF MENU COSTS 819

price changes suggests that the price change decisions in thesesupermarkets have a strong time-dependent price-setting ele-ment36 For example according to Table VI the prices in Chain Aare changed weekly according to the following schedule the pricechanges of general merchandise that is advertised is done Satur-day nights grocery and produce prices are changed Sundaynights the rest of the general merchandise prices are changed onMonday nights and the prices of advertised grocery items arechanged on Tuesday nights Thus as the gures in Table VI indi-cate over 96 percent of the price changes are done during Sundayand Monday nights However this does not imply that state-dependent pricing rules are unimportant Even if price changesacross product categories follow a prescheduled weekly time ta-ble the prices of which products to change is likely to be a state-dependent decision For example it could depend on changes insupply and demand conditions such as competitorsrsquo price changedecisions Indeed Levy Dutta and Bergen [1996] use retailstore-level orange juice price and cost data to demonstrate thatthe extent of price response to cost shocks that is the extent ofprice rigidity may depend on the nature of supply shocks37

We do not want to overstate the usefulness of our data fordirectly addressing the issue of monetary nonneutrality On onehand authors such as Caplin and Spulber [1987] have demon-strated that under certain conditions individual price rigiditymay not be sufcient for aggregate price rigidity but unfortu-nately our data do not speak directly to this issue38 On the otherhand authors such as Akerlof and Yellen [1985] Mankiw [1985]Parkin [1986] and Caplin and Leahy [1997] have shown that even

36 Danziger [1983] Caballero [1989] and Ball and Mankiw [1994] suggestthat time-dependent price adjustment of the type documented here can be optimalif the cost of gathering information about the state exceeds the cost of making theprice adjustment itself

37 We also considered the possibility of convexities in the cost of changingprices Our data do not suggest many convexities since the labor time spent inthe price tag change process the cost of printing and delivering price tags andin-store supervision time do not change with the size of a price change The onlymeasurable component of menu costs that could be convex is the cost of mistakesmade the larger the price change the higher the probability of a customer notic-ing the mistake and the larger the amount required to be refunded as compensa-tion Among the unmeasured components of menu cost the cost of corporatemanagerial time may increase with the size of a price change because larger pricechanges may require more serious consideration

38 Also see Balke and Wynne [1996] and Bryan and Cecchetti [1996] Sincewe do not have measures of how menu costs change over time our data also havelittle to say about time variation in menu costs or about the relationship betweenmenu costs and ination which during the period of the data collection (1991ndash1992) averaged about 3 percent annually

small menu costs can be relevant since they may be sufcient togenerate substantial aggregate nominal rigidity and thus largebusiness cycles Therefore as Blinder [1994] Kashyap [1995]and Slade [1996a] emphasize it is important to search for directevidence that such costs are indeed present at the micro level Bydirectly identifying documenting and measuring the magnitudeof menu costs at the store level we are taking an important stepin that direction

VI CONCLUSION AND FUTURE RESEARCH

Our main contribution is that we provide direct microeco-nomic evidence on the actual magnitude of menu costs for fourlarge U S retail supermarket chains The annual menu costs perstore at these chains average $105887 comprising 070 percentof revenues 352 percent of net prot margins and $052 perprice change on average

Further we provide evidence which suggests that thesemenu costs may be forming a barrier to price changes Specifi-cally we show that (1) supermarket chains not subject to itempricing law change prices two and a half times more frequentlythan the chain that is subject to the law (2) within the chain thatis subject to the item pricing law they change prices over threetimes as frequently for products that are exempt from this lawthan for the products which are subject to this law and (3) wend that these chains do not adjust prices of up to one-third ofthe products for which they face cost increases because of menucost considerations

When we relate these ndings to the existing theoreticalmodels of menu costs we conclude that the magnitude of menucosts we nd is large enough to be capable of having macroeco-nomic signicance Specically when considered in the context ofthe theoretical menu cost models of Blanchard and Kiyotaki[1987] and Ball and Romer [1990] we nd that the menu costgures we report are ldquonontrivialrdquo and their relative magnitudescross the minimum theoretical threshold needed to form a barrierto price adjustments

Despite the high relative magnitude of the marginal cost ofchanging price that we found the data still indicate frequentweekly price changes This is because of the high marginal bene-t of changing price which is due to the erce competition foundin the retail supermarket industry That marginal benets may

outweigh the marginal costs of changing prices in this industryhowever does not rule out the possibility that menu costs of themagnitude we nd here can create substantial nominal rigidityin other industries or markets In less competitive industries andmarkets menu costs of the type and magnitude we documenthere are likely to have a bigger impact on the frequency of priceadjustment and consequently on the degree of price rigidity

At a minimum the direct dollar measures of menu costs wereport here can be used as a starting point for future research onmeasuring their magnitude in other industries and establish-ments We anticipate that these menu costs will be similar inother markets which rely on posted prices (such as drugstoresdepartment stores etc) because the steps involved in the pricechange process are likely to be similar What may differ are thefrequency of price changes and the labor wage rates at thesestores For example since supermarket chains change thousandsof prices each week the total annual menu costs incurred bythese chains per store are likely to be high in comparison to otherretail formats such as chain drugstores or department storesThere are however a variety of industries for which the stepsinvolved in changing prices would be signicantly different fromthose reported in our study For example business-to-businesssales which often rely on a sales force will require changes in thelist price sheets changes in the instructions to the sales forcewhich may include education and discussion with the salespeoplein the company and so forth These business-to-business pricesalso often have more complex pricing schemes including quantitydiscounts bundling and individually negotiated prices As an-other example the composition of the cost of changing the news-stand prices of magazines [Cecchetti 1986] or the prices ofproducts sold through catalogs [Kashyap 1995] are different frommany of the menu cost components we discuss here Further thending that a centralization of pricing decisions makes the store-level managerial component of menu cost relatively small sug-gests that the managerial menu costs likely are highest insettings where price change decisions are decentralized Thus fu-ture empirical work should look at menu cost and its compositionin a variety of other industries markets and products with bothcentralized as well as decentralized price change decisions in or-der to see whether the magnitude of these costs can be general-ized and benchmarks can be established Further there aretechnological changes taking place in this and other industries

that promise to alter the structure of menu costs which deserveattention At the theoretical level our ndings suggest that it maybe worthwhile to explore models which incorporate the idea ofitem pricing laws as an additional component of menu costs

THE MAGNITUDE OF MENU COSTS 825

V3 Relating Our Findings to the Existing Theoretical Models ofMenu Costs

In order to assess the magnitude of these menu cost guresin the context of the existing theoretical menu cost literatureconsider the following calculation experiments done within theframework of two theoretical menu cost models Blanchard andKiyotaki [1987] study a general equilibrium menu cost modelwith monopolistic competition and with unit elasticity of aggre-gate demand with respect to real money balances According totheir calculations menu costs of the magnitude of 008 percent ofrevenues which they consider ldquovery smallrdquo may be sufcient toprevent adjustment of prices Ball and Romer [1990] conductsimilar calculations in the framework of a model with imperfectcompetition and menu costs They nd that for plausible markupand labor elasticity parameter values menu costs needed to pre-vent price adjustment are 070 percent of revenues which as theysuggest are nonnegligible For smaller menu costs eg 004 per-cent of the revenue which Ball and Romer consider ldquotrivialrdquo im-plausibly large values of markup and labor elasticity parametersare needed to prevent price adjustment to monetary shocks

According to the gures in Table IV the reported menu costto revenues ratio for Chains AndashD averages 070 percent rangingfrom 061 percent to 076 percent These are signicantly largerthan the ldquotrivialrdquo 004 or 008 percent gures mentioned abovesuggesting that the menu cost gures we nd here are nontrivialFurther under the model and parameter values considered byBlanchard and Kiyotaki [1987] the menu cost gures we nd arehigher than the theoretical minimum needed to form a barrier toprice adjustments Under the model and parameter values con-sidered by Ball and Romer [1990] the reported menu costreve-nue ratio for all but one chain reaches or crosses the theoreticalthreshold of 070 needed to form a barrier to price adjustmentsThe existence of numerous unmeasured menu cost componentsdiscussed in subsection III5 also raises the possibility that theactual menu costs incurred by these chains are signicantlyhigher than that threshold This suggests that the menu costs wereport may be large enough to form a barrier to nominal priceadjustments when interpreted in the context of these models

An issue of interest in this literature is time-dependent ver-sus state-dependent pricing rules (see for example Caplin andLeahy [1991]) The evidence from our data set on the timing of

THE MAGNITUDE OF MENU COSTS 819

price changes suggests that the price change decisions in thesesupermarkets have a strong time-dependent price-setting ele-ment36 For example according to Table VI the prices in Chain Aare changed weekly according to the following schedule the pricechanges of general merchandise that is advertised is done Satur-day nights grocery and produce prices are changed Sundaynights the rest of the general merchandise prices are changed onMonday nights and the prices of advertised grocery items arechanged on Tuesday nights Thus as the gures in Table VI indi-cate over 96 percent of the price changes are done during Sundayand Monday nights However this does not imply that state-dependent pricing rules are unimportant Even if price changesacross product categories follow a prescheduled weekly time ta-ble the prices of which products to change is likely to be a state-dependent decision For example it could depend on changes insupply and demand conditions such as competitorsrsquo price changedecisions Indeed Levy Dutta and Bergen [1996] use retailstore-level orange juice price and cost data to demonstrate thatthe extent of price response to cost shocks that is the extent ofprice rigidity may depend on the nature of supply shocks37

We do not want to overstate the usefulness of our data fordirectly addressing the issue of monetary nonneutrality On onehand authors such as Caplin and Spulber [1987] have demon-strated that under certain conditions individual price rigiditymay not be sufcient for aggregate price rigidity but unfortu-nately our data do not speak directly to this issue38 On the otherhand authors such as Akerlof and Yellen [1985] Mankiw [1985]Parkin [1986] and Caplin and Leahy [1997] have shown that even

36 Danziger [1983] Caballero [1989] and Ball and Mankiw [1994] suggestthat time-dependent price adjustment of the type documented here can be optimalif the cost of gathering information about the state exceeds the cost of making theprice adjustment itself

37 We also considered the possibility of convexities in the cost of changingprices Our data do not suggest many convexities since the labor time spent inthe price tag change process the cost of printing and delivering price tags andin-store supervision time do not change with the size of a price change The onlymeasurable component of menu costs that could be convex is the cost of mistakesmade the larger the price change the higher the probability of a customer notic-ing the mistake and the larger the amount required to be refunded as compensa-tion Among the unmeasured components of menu cost the cost of corporatemanagerial time may increase with the size of a price change because larger pricechanges may require more serious consideration

38 Also see Balke and Wynne [1996] and Bryan and Cecchetti [1996] Sincewe do not have measures of how menu costs change over time our data also havelittle to say about time variation in menu costs or about the relationship betweenmenu costs and ination which during the period of the data collection (1991ndash1992) averaged about 3 percent annually

QUARTERLY JOURNAL OF ECONOMICS820

small menu costs can be relevant since they may be sufcient togenerate substantial aggregate nominal rigidity and thus largebusiness cycles Therefore as Blinder [1994] Kashyap [1995]and Slade [1996a] emphasize it is important to search for directevidence that such costs are indeed present at the micro level Bydirectly identifying documenting and measuring the magnitudeof menu costs at the store level we are taking an important stepin that direction

VI CONCLUSION AND FUTURE RESEARCH

Our main contribution is that we provide direct microeco-nomic evidence on the actual magnitude of menu costs for fourlarge U S retail supermarket chains The annual menu costs perstore at these chains average $105887 comprising 070 percentof revenues 352 percent of net prot margins and $052 perprice change on average

Further we provide evidence which suggests that thesemenu costs may be forming a barrier to price changes Specifi-cally we show that (1) supermarket chains not subject to itempricing law change prices two and a half times more frequentlythan the chain that is subject to the law (2) within the chain thatis subject to the item pricing law they change prices over threetimes as frequently for products that are exempt from this lawthan for the products which are subject to this law and (3) wend that these chains do not adjust prices of up to one-third ofthe products for which they face cost increases because of menucost considerations

When we relate these ndings to the existing theoreticalmodels of menu costs we conclude that the magnitude of menucosts we nd is large enough to be capable of having macroeco-nomic signicance Specically when considered in the context ofthe theoretical menu cost models of Blanchard and Kiyotaki[1987] and Ball and Romer [1990] we nd that the menu costgures we report are ldquonontrivialrdquo and their relative magnitudescross the minimum theoretical threshold needed to form a barrierto price adjustments

Despite the high relative magnitude of the marginal cost ofchanging price that we found the data still indicate frequentweekly price changes This is because of the high marginal bene-t of changing price which is due to the erce competition foundin the retail supermarket industry That marginal benets may

THE MAGNITUDE OF MENU COSTS 821

outweigh the marginal costs of changing prices in this industryhowever does not rule out the possibility that menu costs of themagnitude we nd here can create substantial nominal rigidityin other industries or markets In less competitive industries andmarkets menu costs of the type and magnitude we documenthere are likely to have a bigger impact on the frequency of priceadjustment and consequently on the degree of price rigidity

At a minimum the direct dollar measures of menu costs wereport here can be used as a starting point for future research onmeasuring their magnitude in other industries and establish-ments We anticipate that these menu costs will be similar inother markets which rely on posted prices (such as drugstoresdepartment stores etc) because the steps involved in the pricechange process are likely to be similar What may differ are thefrequency of price changes and the labor wage rates at thesestores For example since supermarket chains change thousandsof prices each week the total annual menu costs incurred bythese chains per store are likely to be high in comparison to otherretail formats such as chain drugstores or department storesThere are however a variety of industries for which the stepsinvolved in changing prices would be signicantly different fromthose reported in our study For example business-to-businesssales which often rely on a sales force will require changes in thelist price sheets changes in the instructions to the sales forcewhich may include education and discussion with the salespeoplein the company and so forth These business-to-business pricesalso often have more complex pricing schemes including quantitydiscounts bundling and individually negotiated prices As an-other example the composition of the cost of changing the news-stand prices of magazines [Cecchetti 1986] or the prices ofproducts sold through catalogs [Kashyap 1995] are different frommany of the menu cost components we discuss here Further thending that a centralization of pricing decisions makes the store-level managerial component of menu cost relatively small sug-gests that the managerial menu costs likely are highest insettings where price change decisions are decentralized Thus fu-ture empirical work should look at menu cost and its compositionin a variety of other industries markets and products with bothcentralized as well as decentralized price change decisions in or-der to see whether the magnitude of these costs can be general-ized and benchmarks can be established Further there aretechnological changes taking place in this and other industries

that promise to alter the structure of menu costs which deserveattention At the theoretical level our ndings suggest that it maybe worthwhile to explore models which incorporate the idea ofitem pricing laws as an additional component of menu costs

THE MAGNITUDE OF MENU COSTS 825

small menu costs can be relevant since they may be sufcient togenerate substantial aggregate nominal rigidity and thus largebusiness cycles Therefore as Blinder [1994] Kashyap [1995]and Slade [1996a] emphasize it is important to search for directevidence that such costs are indeed present at the micro level Bydirectly identifying documenting and measuring the magnitudeof menu costs at the store level we are taking an important stepin that direction

VI CONCLUSION AND FUTURE RESEARCH

Our main contribution is that we provide direct microeco-nomic evidence on the actual magnitude of menu costs for fourlarge U S retail supermarket chains The annual menu costs perstore at these chains average $105887 comprising 070 percentof revenues 352 percent of net prot margins and $052 perprice change on average

Further we provide evidence which suggests that thesemenu costs may be forming a barrier to price changes Specifi-cally we show that (1) supermarket chains not subject to itempricing law change prices two and a half times more frequentlythan the chain that is subject to the law (2) within the chain thatis subject to the item pricing law they change prices over threetimes as frequently for products that are exempt from this lawthan for the products which are subject to this law and (3) wend that these chains do not adjust prices of up to one-third ofthe products for which they face cost increases because of menucost considerations

When we relate these ndings to the existing theoreticalmodels of menu costs we conclude that the magnitude of menucosts we nd is large enough to be capable of having macroeco-nomic signicance Specically when considered in the context ofthe theoretical menu cost models of Blanchard and Kiyotaki[1987] and Ball and Romer [1990] we nd that the menu costgures we report are ldquonontrivialrdquo and their relative magnitudescross the minimum theoretical threshold needed to form a barrierto price adjustments

Despite the high relative magnitude of the marginal cost ofchanging price that we found the data still indicate frequentweekly price changes This is because of the high marginal bene-t of changing price which is due to the erce competition foundin the retail supermarket industry That marginal benets may

At a minimum the direct dollar measures of menu costs wereport here can be used as a starting point for future research onmeasuring their magnitude in other industries and establish-ments We anticipate that these menu costs will be similar inother markets which rely on posted prices (such as drugstoresdepartment stores etc) because the steps involved in the pricechange process are likely to be similar What may differ are thefrequency of price changes and the labor wage rates at thesestores For example since supermarket chains change thousandsof prices each week the total annual menu costs incurred bythese chains per store are likely to be high in comparison to otherretail formats such as chain drugstores or department storesThere are however a variety of industries for which the stepsinvolved in changing prices would be signicantly different fromthose reported in our study For example business-to-businesssales which often rely on a sales force will require changes in thelist price sheets changes in the instructions to the sales forcewhich may include education and discussion with the salespeoplein the company and so forth These business-to-business pricesalso often have more complex pricing schemes including quantitydiscounts bundling and individually negotiated prices As an-other example the composition of the cost of changing the news-stand prices of magazines [Cecchetti 1986] or the prices ofproducts sold through catalogs [Kashyap 1995] are different frommany of the menu cost components we discuss here Further thending that a centralization of pricing decisions makes the store-level managerial component of menu cost relatively small sug-gests that the managerial menu costs likely are highest insettings where price change decisions are decentralized Thus fu-ture empirical work should look at menu cost and its compositionin a variety of other industries markets and products with bothcentralized as well as decentralized price change decisions in or-der to see whether the magnitude of these costs can be general-ized and benchmarks can be established Further there aretechnological changes taking place in this and other industries
