We explore the effectiveness of capital controls in Colombia. We analyze the impact of administrativerestrictions to capital flows on aggregate capital flows, the composition of capital flows, the real exchangerate, and economic activity using restricted versions of vector error correction models (VEC) that controlfor exogenous global financial conditions. The models are estimated using monthly data ranging fromAugust of 1998 to May of 2008. In addition we estimate GARCH models to identify if capital controls havehad relevant impacts on the volatility of the nominal exchange rate and of other relevant asset prices.These models are estimated using weekly data covering the same time period. Results suggest that the

In addition there is no evidence suggesting a change in the compositionof capital flows induced by capital controls.

. Introduction

Financial liberalization and economic globalization can bemportant drivers of long term economic growth.2 Despitevidence pointing towards long term benefits of financial lib-ralization, there is consensus that globalization leads to policyilemmas associated with the volatility of capital flows in the shortun.3 When capital flows into a country, there is a risk of real

xchange rate appreciation, which may harm the potential devel-pment of tradable sectors. The severity of such problems has ledolicy makers in different parts of the world to adopt policies that

nclude capital controls to contain capital flows, particularly shorterm ones, limit the appreciation of domestic currencies, and avoidudden reversals of capital flows in turbulent times.4

Colombia has had a long tradition with capital controls. In factt is difficult to identify relatively long periods of time in recentistory in which capital controls have not been in place. Evenfter the adoption of several economic liberalization policies in thearly 1990s, that in theory included a liberalization of the capitalccount, capital controls have remained in place. During the pastwo decades, policy makers have used capital controls based on theremise that short term capital flows are harmful for the economynd need to be contained.

The instrument most commonly used to control capital flowsuring the past decade and a half, has been a Chilean style unremu-erated reserve requirement or deposit on portfolio flows and shorterm debt. The purpose of this policy has been to disincentive short

erm flows, by making short term debt costlier or alternatively byiminishing the returns of portfolio investments.5

4 Some justifications for capital controls can be found in Krugman (1987),ichengreen, Tobin, and Wyplosz, 1995, and Kaplan and Rodrik (2001). Calvo (2010)rovides a skeptical view on capital flows and its distortive impacts.5 For many years, and until the beginning of the 1990s, capital controls were ori-

nted to limit capital outflows. Since the 1990s, capital controls have been orientedo diminish capital inflows, alter their composition in favor of long term capitalows, and avoid the appreciation of the Colombian peso.

20 A. Concha et al. / The Quarterly Review o

There is a wide range of studies carried out in different coun-ries that raise doubts about the effectiveness of capital controlsn terms of limiting capital flows and altering the trend of the realxchange rate. Despite the fact that some evidence suggests thathe composition of capital flows can be altered through capital con-rols, research supporting impacts on maintaining the exchangeate undervalued or reducing aggregate capital flows is very scarce.

The Chilean experience with capital controls is consideredaradigmatic by many authors and has been subject to consid-rable analysis. In most cases, empirical evidence indicates thatapital controls had an impact on the composition of foreign debtn favor of longer maturities but had no significant impact on keep-ng the local currency undervalued or reducing aggregate capitalows.6 Recently, a macro-prudential objective has also been linkedo capital controls, namely the possibility of reducing over borrow-ng during booms to avoid costly financial crises in the future.7 The

acro prudential objective can be achieved as long as the capitalontrols are effective. There is also some evidence suggesting thatapital controls contribute to diminish financial volatility, which islso considered an objective, though a second order one, of theseolicies.8

Studies for the Colombian case are not conclusive, though mostvidence obtained through various techniques and different dataets suggests that capital controls have had little impact on con-aining exchange rate appreciation. There is some consensus on thempact of capital controls on diminishing short term flows. Someuthors argue that as in Chile, capital controls have altered the com-osition of capital flows, but have not affected total capital flowsr the real exchange rate. Cárdenas and Barrera (1997) find thathe capital controls implemented between 1985 and 1995 had nompact on total capital flows but changed their composition. A sim-lar finding is reported by Rocha and Mesa (1998) who argue thaturing a similar period, capital controls reduced the short term

nterest rate differential reducing medium and long term foreignebt. Using a data set that covers the period between 1993 and998, Ocampo and Tovar (1999), Ocampo and Tovar (2003), Villarnd Rincón (2000) and Rincón (2000) argue that capital controlsiminished not only short term but also long term capital flows.

It is worth noting that these studies covered mostly a timeeriod in which the exchange rate was either managed through

crawling peg regime (up to 1993) or was partially managed in target zone (1993–1998). To our knowledge only this paper andlements and Kamil (2009) focus exclusively on a time period of

floating exchange regime in which one could argue that capi-al controls could play a stronger role in containing exchange rate

ppreciation and volatility, as opposed to before when much of thisas tried through administrative controls of the exchange rate.lements and Kamil (2009) focus on the controls implemented

6 De Gregorio, Edwards, and Valdes (1998), De Gregorio, Edwards, and Valdes2000) analyze the effects of the non remunerated deposit on capital flows in Chileetween 1991 and 1998 on the interest rate, the real exchange rate, the volume andhe composition of capital flows. They find that capital controls had a significantffect on the composition of capital flows and increased temporarily the real inter-st rate. They also find that the impact on the real exchange rate is transitory andanishes rapidly.7 See Bianchi (2009) or Korinek (2009) for a discussion.8 Edwards (1999) estimates GARCH models and finds that even if capital con-

rols contributed to diminish volatility, they were not enough to isolate Chile fromlobal shocks particularly during the Asian crisis. Edwards and Rigobón (2005) showhat capital controls helped diminish the impact of external shocks on the nom-nal exchange rate, and despite that they increase the unconditional volatility ofhe exchange rate, they also reduced its sensitivity to shocks. Kaplan and Rodrik2001) suggest for the Malasian case, that capital controls contributed to increasehe effectiveness of monetary policy and the speed of recovery following the crisisf the 1990s.

ince 2007 and find that they were successful in limiting externalorrowing, but had no significant impact on the volume of non-FDIows nor moderated the appreciation of the peso.

This paper looks at a wider time frame than most of the Colom-ian studies cited above and focuses on the whole period ofxchange rate flexibility (1998–2008).9 We consider that doinghis diminishes problems associated with credibility issues of theegs or quasi-pegs that may impact the way that the exchange rateesponds to fundamentals that if not controlled for can distort theelationships that we wish to identify.

Also, and as opposed to Clements and Kamil, we explore not onlyontrols on debt flows regulated by the Central Bank, but also con-rols on portfolio flows regulated either by the National Planningepartment (DNP) or the Ministry of Finance. Controls during theast decade have been both on portfolio flows as well as on foreignhort term debt. While most studies have focused only on controlsn short term foreign debt, we include in our analysis controls onortfolio flows as well. This is also a difference with respect to othertudies referenced above.

An important feature of our paper is that as in Ocampo andovar (1999), Rincón (2000) and Clements and Kamil (2009) weontrol for external factors that can alter capital flows and whosempact can sometimes be confused with that of capital controls. Ifontrols are implemented at the same time that global risk percep-ions increase, both events may lead to similar expected outcomesn terms of capital inflows and exchange rate behavior. However todentify the precise impact of each of them, it is crucial to controlor the other.

In addition, the methodology that we follow, allows us to ade-uately deal with certain endogeneity issues that come about inhis sort of analysis, and allows us to impose exogeneity restric-ions on the variables that measure global financial conditions anderms of trade fluctuations. This contributes to the precise identi-cation of the impact of changes in capital control policies on thendogenous variables of our study.

The empirical analysis is divided in two sections. First, wexplore the impact of capital controls on aggregate capital flows,he composition of capital flows (short vs. long term flows) the realxchange rate and economic activity in a vector error correctionVEC) model. Second, we analyze the impact of capital controls onnancial volatility using GARCH models.

Our findings suggest that capital control policies implementedn Colombia after 1998 have been ineffective in limiting the appre-iation of the domestic currency and reducing capital flows. We doot find evidence in favor of a change in the composition of capi-al flows. With respect to a reduction in financial volatility we findtatistical evidence in favor of this, but the impact is not relevantrom an economic point of view.

The paper has 6 parts. In part 2 we describe capital control poli-ies in Colombia. Part 3 describes a capital controls measure thats used for the empirical analysis in parts 4 and 5. Part 4 presentshe methodology and results of assessing the impacts of capitalontrols on capital flows, capital flows’ composition and the realxchange, and part 5 does the same for our analysis on the impact

f capital flows on asset price volatility. Part 6 presents some finalemarks.

9 Previous studies cover periods with different exchange rate regimes that include crawling peg, an exchange rate band, a transition regime between these two, and flotation regime, and do not include strategies to deal with regime shifts. It isorthwhile noting that since our sample differs from the sample used in other

tudies, the comparison of our results with those of other studies must be doneith caution.

. Capital controls in Colombia

The use of capital controls in Colombia is by no means a recentolicy. Between 1967 and 1991, a very restrictive regime on capitalows was in place. Every foreign debt flow, either private or public,ad to be approved by the central bank.

During the first half of 1991, many administrative controls toapital flows were removed. In January of 1991, Law 9 that startedith the liberalization of capital flows was approved by Congress.

ome controls were lifted, and the monopoly of the central bank ashe unique foreign exchange market participant was also removedllowing additional intermediaries to participate in the exchangef foreign currency. Later that year, in June, with the expeditionf resolution 91, private foreign debt for maturities lower than2 months was fully liberalized, and minimum restrictions were

mposed for maturities greater than one year.10

In September of 1993 in the midst of a new wave of cap-tal inflows that were exerting pressure on strengthening theolombian peso, policy makers inspired on the Chilean experience,

mposed capital controls in the form of a non-remunerated depositn private foreign debt. The rationale for this policy was to reducehe exposure of the economy to the volatility of capital flows, par-icularly short term speculative ones. Initially the deposit was sett 47% of the foreign loan for a twelve month period. Since then andntil the year 2000, both the percentage of the reserve requirement,s well as the duration of the deposit were changed several times.n the year 2000 the deposit was set at a 0% rate. Panel (a) of Table 1hows the detailed evolution of capital controls in Colombia.

In May 2007, the Central Bank, reestablished the deposit on for-

ign debt, once again to contain the appreciating trend that theolombian peso had been following since 2003.11 The deposit waset at 40% of the disbursement of the foreign loan, for a six month

eriod, and at 11% of disbursement of loans to pre-finance exportsor a twelve month period. This policy was kept in place untileptember 2008, when the deposit was set back to 0%.

Besides controls to short term foreign indebtedness, Colombianolicy makers have also imposed restrictions on portfolio invest-ents. Policies have ranged from completely forbidding short term

nvestments from abroad (2004–2006) to imposing deposits sim-lar to those on short term debt. In May 2007, a non remuneratedeposit on 40% of the portfolio investment was imposed for a sixonth period after an attempt of prohibiting short term foreign

ortfolio flows nearly two years before. Panel (b) of Table 1, sum-arizes these policies.12

Literature has shown that capital controls are subject to a vari-ty of loopholes. De Gregorio, Edwards, and Valdes (2000) showhat during the times they were used in Chile, several loopholesere closed in order to increase their effectiveness. During the timeeriod analyzed in this paper, only one mayor loophole was closedhough adjustments to regulation. Through its external resolutiono. 1 of 2008, in late April, the Central Bank closed an important

oophole by extending the deposit to foreign affiliates of Colombianrms that issued debt abroad, and transferred it to its Colombianounterpart as a capital investment. This loophole allowed many

y the nationality of the investors. Controls apply to all cross border foreign cur-ency transactions subject to the control, regardless of the nationality of the agentsarrying them out. In order to explore the role of residents positions in foreignxchange see Arbelaez and Steiner (2009) who analyze the role played by largeesident investors such as private pension funds in explaining exchange rate volatil-ty. Their research suggests that exchange rate transactions by such players do notxplain volatility. They also find that volatility is heavy influenced by the Treasury’sransactions or Central Bank interventions.13 Anecdotal evidence gathered by the authors with different sources suggests thathis was a common practice during the capital control periods.

Our purpose here is to analyze the impact of these controlsn relevant endogenous variables such as the trend of the realxchange rate, total capital flows, the composition of capital flowsnd the volatility of financial variables.

. Measuring the intensity of capital controls

Evaluating the impact of capital controls requires the construc-ion of an indicator that measures the intensity of such policy. Forhis purpose we follow closely what has been done in the previousiterature on this field. Following Valdés-Prieto and Soto (1996), Deregorio, Edwards, and Valdes (1998), De Gregorio, Edwards, andaldes (2000) and Edwards (1999) among others, we construct a

ax equivalent measure of capital controls that reflects the implicitremium paid on local returns to compensate investors for thenancial costs associated with capital controls. The calculation ofhe tax equivalent measure depends on the type of capital con-rol imposed, and varies depending on whether it is in the form of

reserve requirement or a prohibition to certain types of capitalows.

In the case of a reserve requirement the tax equivalent is derivedrom the following condition:

1 − �)(1 + ik)k/12(1 + i∗)(h−k)/12 + � = (1 + i∗)h/12 (1)

here � is the reserve requirement, ik the return to investmentsn the local economy, i* the return to investments abroad, k theuration in months of the investment to obtain return ik, and hhe length in months of the requirement. Condition (1) is a nonrbitrage interest rate parity condition that shows that the return tonvestments in the local country net of the costs of capital controls

ust be equal to the return of investments abroad. The longer theuration of the requirement, the higher the premium needed toompensate investors. Eq. (1) can be rewritten as:

1 + i∗ + tx)k/12≡(1 + ik)k/12 = (1 + i∗)k/12 − �(1 + i∗)(h−k)/12

1 − �(2)

olving for tx, we obtain the tax equivalent measure of capitalontrols14:

q. (3) shows that the tax equivalent of capital controls dependsositively on the amount of the reserve requirement (�) and itsuration (h), and negatively on the duration of domestic invest-ents (k). The shorter the duration of investments vis a vis the

uration of the requirements, the costlier the capital controls mea-ure. The tax equivalent also depends positively on i*. The higherhe opportunity cost of investments in the domestic country, theostlier the controls.

In the case of a straight forward prohibition to short term flows,he interest rate parity condition for investments with a maturityhorter than the maturity up to which capital flows are bannedk < h) will be:

s Eq. (3), Eq. (5) also shows how the capital controls policyecomes costlier the longer the duration up to which flows areanned vis a vis the duration of investments.

Fig. 1 shows different estimates of tx for Colombia and for invest-ents with a 1,3, and 6 month maturities. Eq. (3) is used to compute

x in periods in which reserve requirements have been in place, andq. (5) in periods in which investments with durations lower than

year have been banned such as between December 2004 and June006 (Table 1, panel b). We assume that the alternative return of an

nvestment abroad is given by the 6 month Libor rate. The shorterhe maturity of local investments, the higher the cost of capitalontrols.

Once we have constructed this proxy for capital controls inten-ity, we explore its impact on relevant economic variables. Figs. 2nd 3 show the behavior of short and long term capital flows inolombia, the real exchange rate, and the intensity of capital con-rols. The lines in Fig. 2 show capital flows and the shaded region thentensity of capital controls.15 In Fig. 3, the line shows the bilateraleal exchange rate of the peso with respect to the US dollar, and thehaded area, once again indicates the intensity of capital controls.

f controls have led to a slow down in short term capital flowsnd have reduced the appreciating trend of the real exchange rate.owever, it is important to take into account that this slowdown

A rigorous analysis of the impacts of capital controls, shouldake into account several types of shocks, including of course globalnancial ones. This is done in the following sections through twoypes of econometric estimations. First we study the impact ofapital controls on capital flows, the real exchange rate and eco-omic performance, namely exploring if capital controls have hadn impact in detaining capital flows or changing their compositionnd depreciating the real exchange rate. This is done by estimatingector error correction models (VEC) using monthly data spanningrom mid 1998 and until May 2008. Second we explore if capi-al controls have diminished domestic financial volatility, whichs usually considered a second order objective of capital controls.or this, we estimate GARCH models of financial indicators includ-ng the nominal exchange rate, a stock exchange price index, and aublic debt price index, using a weekly data set that covers a similarime period for the exchange rate and the stock price index, but ahorter one, due to data availability for the public debt price index.

. Capital controls, capital flows and the real exchange rate

To estimate the impact of capital controls on macroeconomicariables, we estimate a VEC model including an index of industrial

roduction constructed by the national statistics agency – DANE, aultilateral real exchange rate constructed by the Central Bank of

olombia – Banco de la República, total capital inflows as reportedy the Colombian Central Bank, the tax equivalent measure of

index and capital controls.

apital controls described above,16 an index of terms of trade alsoonstructed by the Central Bank, and the global EMBI spread con-tructed by JP Morgan to control for global financial conditions.ppendix A reports the source and gives additional details on theata set. We estimate the following model:

�yt = c + ˛ˇ′yt−1 + �1�yt−1 + · · ·�p−1�yt−p−1 + ϕDt + εt

yt = (EMBIt, TOTt, Txt, CFt, RERt, IPt)(6)

here EMBI is the spread of emerging markets sovereign bondeturns with respect to US treasuries (in logs), TOT is the termsf trade index (in logs),17 Tx is the tax equivalent measure of cap-tal controls, CF are total net capital flows, RER is the multilateraleal exchange rate index (in logs), IP is the industrial productionndex (in logs), and D a dummy variable capturing changes in thepower” of capital controls as described below.

Previous research has used VARs to test the effectiveness of cap-tal controls.18 Here we use a VEC to account for the fact that mostf the variables involved in our empirical specification are likely to

In this specification, the matrix � includes the partial adjust-ent coefficients of the error correction model, ˇ′yt−1 are the error

In addition, and in order to control for potential loopholes in cap-tal controls, we include a dummy variable labeled “power dummyD)” that takes a value of 1 when controls were strengthened and 0therwise. This dummy should capture the fact that controls mightork when they are initially implemented but as loopholes areiscovered they gradually lose power.19

In our empirical model we allow for the exogeneity of the globalMBI spread and of the terms of trade. To model it we imposeestrictions on the and � matrixes. We assume that the EMBInd terms of trade are exogenous in such a way that their dynam-cs only rely on their past and not on the short term behavior ofhe rest of the variables in the system, nor on the error correctionerms.20 This means that the matrixes and � take the followingorm21:

he estimation of (6)–(7) requires checking first the order ofntegration of the variables and the number of co-integration rela-ionships in the data. We require that at least two of the variables inhe system are I(1). As shown in Appendix B, this condition amplyolds. The ADF and KPSS unit root tests show that the log of theeal exchange rate (log(RER)), long term capital flows (FDI), the taxquivalent of capital controls (Tx), the log of the terms of tradendex (log(TOT)), and the log of the EMBI spread (log(EMBI)) have anit root. The results of the tests are mixed for the log of industrialroduction (log(IP)), total capital flows (CF) and short term capi-al flows (ST CF) in which the ADF rejects the unit root hypothesisnd the KPSS rejects stationarity. Once first differenced, accordingo both tests, all variables are stationary. These results allow us to

stimate the proposed models comfortably.

The estimation of models (6) and (7) requires verifying that theariables are co-integrated, that is that there exists at least one

19 We base this, as suggested by a referee, on the work of De Gregorio, Edwards,nd Valdes (2000). Unfortunately our data does not allow us to replicate the powerariable as constructed there. In Chile, several modifications to the reserve require-ents regulations took place to close important loopholes. In Colombia, according

o our knowledge, the only loophole that was truly closed was done in May 2008, 4onths before capital controls were eliminated, and right at the end of our sample.

he loophole that was closed was one that allowed Colombian firms to get indebtedbroad through a foreign subsidiary and transferring the funds to Colombian branchs a capital investment without being subject to the reserve requirement. The restf modifications were aimed at increasing the reserve requirement.20 We also allowed for specifications in which the EMBI spread and the terms ofrade were correlated, but we did not find significant coefficients and do not reporthem here. Results, nonetheless, were unchanged.21 The model has two deterministic components: the constant and the powerummy. We assume that the coefficient of the power dummy in the EMBI and TOTquations are zero, to guaranty the exogeneity of the global EMBI spread and oferms of trade.

ombination between them that yields stationary residuals, andetermining the number of co-integrating vectors.22 Appendix Chows the results of the co-integration tests for the model withotal capital flows (upper panel) and for the model that dividesetween long and short term flows (lower panel). For the first, theohansen and Saikkonen and Lütkepohl tests suggest evidence ofo-integration, and indicate that there are two co-integration vec-ors at the 5% significance level. For the second model, the testsuggest three co-integration vectors.23

The model is estimated in two stages following Lütkepohl andratzig (2004). In a first stage we estimate the co-integration matrix

with restrictions on ˛. In the second stage we estimate the modelith the � restrictions and include ˇy′

t−1 as a regressor by FGLS.he bottom panels of the tables in Appendix D show LM tests forultivariate serial correlation. The tests reveal that there is no evi-

ence of serial correlation of up to the 12th order. To corroboratehis, in Appendix E, we report the correlation and partial autocor-elation functions of the residuals of each of the equations in theodel. In most equations the residuals appear to be well behaved.owever, there is some evidence of a high order serial correlation

n the IP equation, but due to the amount of parameters that wouldeed to be estimated to control for it, and the fact that the multi-ariate tests reject serial correlation of high orders, we do not dealith it and keep the specification as parsimonious as possible with

ne lag only.24

Appendix D reports the estimation results of the VEC models.e use these estimates to analyze the impact that capital con-

rols have had on the rest of the variables of the model. Recallhat capital controls were put in place to disincentive capital flowsnd reduce the appreciating trend of the Colombian peso. We con-truct impulse response functions of the endogenous variables inhe model with respect to changes in the Tx measure, based on ourstimates reported in Appendix D to test if these goals have beenet.Fig. 4 reports the impulse response functions for the model with

otal capital flows. Each of the columns shows the response of thendogenous variables of the model to a one standard deviationhock of the variables in the model.25 To assess the impact of cap-tal controls on capital flows, industrial production, and the realxchange rate, we should look at the responses of each of these to

shock to Tx (third row of Fig. 4, part a). The results of this exer-ise suggest that capital controls have a non significant effect onhe real exchange rate (third row, third column). This is associatedith a non significant response of capital flows to capital controls

third row, second column). In short, the effect of capital controlsn the relevant economic variables is very close to null.

Fig. 4 also shows that the dynamics of the real exchange rate andf capital flows depend significantly on external factors. The firstow shows the response of the endogenous variables to a one stan-

ard deviation shock of the logarithm of the global EMBI spread0.072). Following an increase in the EMBI spread, industrial pro-uction falls, the real exchange rate depreciates, and capital flows

22 Being co-integrated means that there is at least one stable long-term relation-hip in the variables.23 The number of lags in the VEC model is determined following the Hannan-Quinnriterion. We found the optimal lag length for both models is 1.24 Appendix F reports of the density of the errors in each equation. While therrors are close to normal, Jarque–Bera tests, reject normality in some equations.his however in not an uncommon feature in VAR and VEC estimations.25 Given the EMBI spread and the TOT variables are modeled as exogenous, theiresponse to shocks to other variables in the model is zero and are not reported.n order to identify structural shocks we use the Choleski decomposition of theariance–covariance matrix. As robustness we allow for different ordering of theariables in the model.

iminish. These results are not only statistically significant but alsore important economically. According to our estimations an 7.2%ncrease in the EMBI spread leads to up to a 2% depreciation of theeal exchange rate, and up to a nearly USD 50 million fall in monthlyapital flows.26

In our model we have allowed for the endogeneity of the capitalontrol variable.27 The first column of row 1 shows the response tohe capital controls variable to a rise in the EMBI spread. We findhat when the EMBI spread rises, capital control intensity dimin-shes. This is consistent with the motivation of capital controls inolombia. When global financial conditions are favorable, whichre reflected in a low EMBI spread, and capital flows are abundant,he exchange rate appreciates and economic authorities implementapital controls to try to detain it.

Another result worth noting is that in the first row and thirdolumn of Fig. 4 part b. There, the response of the real exchangeate to a one standard deviation shock of total capital flows (USD60 million) is plotted. A one standard deviation rise in capital flows

eads to a 1% appreciation of the peso.28

Row 1 and column 2 of Fig. 4 part b, shows the response of capitalontrols to a shock in the real exchange rate. As expected when thexchange rate appreciates, capital controls increase. We find thathis has nearly a six month lag.

This initial evidence suggests that capital controls have not beenble to contain currency appreciation or detain capital inflows. Theorecast error’s variance decomposition reported in Appendix Gupports the view that capital controls have played a small rolln explaining capital flows or the real exchange rate, in contrast toxternal variables such as the EMBI spread.

Studies on other countries have also shown that capital controlsave little impact on total capital flows,29 but they suggests thathey have been effective in changing the composition of capitalows in favor of long term flows. To test if this holds for Colombiae re-estimate the model replacing total net capital inflows foret FDI and net short term capital inflows (debt and portfolio) andnalyze similar types of impulse response functions. These resultsre reported in Fig. 5.

The impact of capital controls is observed in the third row of parta) in Fig. 5. Again we find no evidence that capital controls havead a significant impact on the real exchange rate or on short or

ong term capital flows. From this perspective we find no evidenceor Colombia that capital controls have affected the composition ofapital flows as has happened elsewhere.

As in the previous exercise, we see a strong response of endoge-ous variables to external shocks. Net FDI flows, short term capitalows, industrial production, and the real exchange rate exhibit sig-

ificant responses to EMBI spread shocks (Fig. 5 (part a), first row).

n a similar fashion the fourth column of the fourth row of Fig. 5part a) and the forth column of the first row of Fig. 5 (part b),

26 The monthly average of total capital flows during this sample was USD 191illion.

27 This was suggested by an anonymous referee, and follows the work of Cardosond Goldfain (1998) and De Gregorio, Edwards, and Valdes (2000). Our estimatesssuming capital control exogeneity are similar to the ones reported and are avail-ble upon request.28 As noted by one of the referees, one puzzling result is found in the third columnf the second row of Fig. 4 part a, that shows that an increase in terms of trade has ahort lived positive effect on the real exchange rate. We believe that this may happenhen foreign inflation is highly correlated with the terms of trade shock. This may

e the case since much of the terms of trade shocks for Colombia are explainedy increases in oil and other hydrocarbon prices. These are strongly related withlobal inflation. A rise in terms of trade may be correlated in the short run withlobal inflation that may be proportionally higher than the nominal appreciation ofhe peso. This may lead to a short term depreciation of the real exchange rate.29 See De Gregorio, Edwards, and Valdes (2000) for the case of Chile.

how that the real exchange rate is very sensitive to FDI and shorterm capital flows fluctuations. Capital flows, independent of theiromposition, are the major driving force behind currency appre-iation. As above Appendix G reports the forecast error varianceecompositions, that confirm the limited role played by capitalontrols in explaining the endogenous variables of the model, andhe importance of global factors in explaining real exchange rateppreciation.

In order to order to confirm these results we perform severalobustness tests that are reported in Appendices H and I. First andn order to reduce the number of parameters to be estimated, wellow industrial production to enter the model exogenously.30 Thempulse response functions for the model with aggregated capitalows considering this variant are shown in Appendix H. As can beeen this assumption does not change the main results of the paper,nd the finding of no effects of capital controls on capital flows andhe real exchange rate remain.

Finally, and since we are using a Cholesky decomposition of theariance covariance matrix of the VEC model, we allow for dif-erent orderings of the variables in order to test if changes in thessumption of contemporaneous responses of the variables affecthe main results. To limit the amount of space used to report theseesults and allow the reader to focus on the main variables of anal-sis in this study, in Appendix I we plot the impulse responseunctions of aggregate capital flows and the real exchange rateo changes in the capital controls policy variable for seven alter-ative orderings of the variables in the model. Results remainnchanged.

. Capital controls and financial volatility

The results derived from the VEC analysis suggests that capitalontrols have not been useful in Colombia to limit exchange rateppreciation, detain capital flows or alter their composition. Thisvidence suggests that market participants frequently find ways ofypassing the controls and take advantage of return differentials ofomestic financial assets vis a vis foreign ones. Even if this is true,

t is likely that the sophisticated mechanisms developed by marketarticipants may lead to a reduction in foreign exchange move-ents or a reduction in the frequency of transactions. In such case

t is likely that capital controls, even if not having a direct impact onhe permanent level of the exchange rate, may have an impact on itsolatility as well as on the price of other financial assets. To explorehis hypothesis we estimate an empirical model that captures thempact of capital controls on the volatility of financial indicators.pecifically we estimate the following GARCH specification on a setf financial variables:

t = f (xt) + εt (8)

2t = ϕ + ˛1ε2

t−1 + ˛2�2t−1 + ˛3txt + ˛4Extt + t (9)

here Eq. (8) is the mean equation and (9) the variance equationf a financial variable x. The model is estimated using the nominalxchange rate (TRM), the Colombian Stock Exchange price indexIGBVC), and a public bond price index constructed by Corficolom-iana a local investment bank (IDP), as dependent variables. As

proxy for capital controls we use the same variable tx definedbove, and a dummy variable that takes values of 1, when con-rols have been in place and zero otherwise (DUM control). As

ontrols for international capital markets conditions, once again,e use the global EMBI spread. In Eq. (8) we control for lags

f the dependent variable chosen based on the autocorrelation

ndex.The first column of each table reports the estimation of a

ARCH(1,1) model that does not include additional controls (theost possible parsimonious model that yields white noise residu-

ls is presented). In columns (2) and (3) we control for the capitalontrols proxies (first we use the tax equivalent measure, then theapital controls dummy), and in columns (4) and (5) we control fornternational financial conditions (log(EMBI)).

Results reported in Table 2 show that capital controls have had statistically significant negative impact on the volatility of theominal Exchange rate. Results reported in columns (2)–(5) showegative and statistically significant coefficients, accompanying theapital controls proxies. Despite the fact that the coefficients aretatistically significant, the economic impact of capital controls onolatility is low. A one standard deviation increase in the capitalontrols tax equivalent measure (1.7) reduces the variance of thexchange rate between 1.2 and 1.8% depending on the specificationonsidered. An increase of the dummy variable from zero to oneeduces the variance in something between 2 and 2.6%.

Once again the volatility of the Exchange rate is closely linkedo International financial conditions. In all specifications the EMBIpread turns out to be positive and significant. According to theseesults a one standard deviation increase in the log of the EMBIpread (0.6) increases the variance of the nominal exchange raten something between 55 and 62% with respect to the estimatedverage of the variance. These results suggest that global finan-ial instability has severe impacts on the stability of the exchangeate, and these impacts are far more relevant than those of capital

ontrols.

Tables 3 and 4 show similar estimations for the IGBVC and IDP.n Table 3 the tax equivalent of capital controls appears significantn column 2, but this result is lost when controlling for international

tcfi

nancial conditions in column 4. In Table 4 we do not find anyignificant evidence of capital controls affecting volatility. Asbove, international financial conditions captured in the change inhe log of the EMBI spread are positive and significant. Internationalurmoil increases the volatility of any kind of financial asset.

. Concluding remarks

Despite a long tradition with capital controls in Colombia, theres no evidence that supports their effectiveness. This paper exploreshe impact of capital controls from different perspectives. We findo significant evidence suggesting an impact of capital controls onotal capital flows, the composition of capital flows, and the realxchange rate. We do find some evidence suggesting a reductionn exchange rate volatility, though the impacts are not significantrom an economic point of view. Our findings raise doubt on thesefulness of capital controls in Colombia, not only to mitigateeal exchange appreciation, but also as a macro prudential tool,ince we find no evidence of their contribution to reduce foreignndebtedness.

Regarding the lack of effectiveness of capital controls, we arenclined to think that the existence of the large loopholes describedn the paper, explain our finding. During most of the period of theirmplementation, agents were able to transfer short term debt flowsrom affiliates abroad disguised as capital investment. To the extenthat this was a frequent practice, controlling short term debt flowshrough administrative policies was innocuous. The presence ofuch a loophole may explain the differences between our findingsnd the evidence found in Chile on the ability of capital controls tohare the term-profile of capital flows.

It is worthwhile noting the impact of external variableshroughout the exercises carried out in this paper. In all specifi-ation the global EMBI spread turns out to be significant. Externalnancial conditions are important determinants of fluctuations in
