Widespread support for capital account liberalization in emerging markets has recently shifted to skepticism and even support for capital controls in certain circumstances. This sea-change in attitudes has been bolstered by the inconclusive macroeconomic evidence on the benefits of capital account liberalization. There are several compelling reasons why it is difficult to measure the aggregate impact of capital controls in very different countries. Instead, a new and more promising approach is more detailed microeconomic studies of how capital controls have generated specific distortions in individual countries. Several recent papers have used this approach and examined very different aspects of capital controls - from their impact on crony capitalism in Malaysia and on financing constraints in Chile, to their impact on US multinational behavior and the efficiency of stock market pricing. Each of these diverse studies finds a consistent result: capital controls have significant economic costs and lead to a misallocation of resources. This new microeconomic evidence suggests that capital controls are not just "sand", but rather "mud in the wheels" of market discipline

[pt] Esta dissertação analisa a eficácia dos controles de entrada de capitais em restringir e selecionar fluxos financeiros internacionais. A maior contribuição é o foco nas elisões dos controles realizadas pelo mercado financeiro e seus efeitos limitadores na eficácia das restrições ao capital de curto prazo. Primeiro, apresentamos uma abordagem teórica da questão, discutindo como o controle deveria ser implementado. O modelo tem um arcabouço simples e considera dois tipos de investidores: paciente e impaciente. O primeiro (que se deseja atrair) tem maior interesse no retorno de longo prazo e o segundo (que não se deseja atrair) dá maior valor a ganhos de curto prazo. Mostramos que se o diferencial de juros é endógeno à fixação dos controles, e não há possibilidades de elisão das regulações, então pode ser concebido um mecanismo de taxação à entrada de capitais que induz à opção de investir a longo prazo para ambos os investidores, na ausência de crises de confiança. Se vier a se realizar uma probabilidade de default maior que a esperada pelo agente, o investimento será revertido, a não ser que seja oferecido um maior diferencial de taxa de juros. Controles ex-post de saída de capitais também poderiam evitar a reversão do investimento, entretanto, nós não consideramos esta possibilidade devido à grande perda de reputação que ela acarreta. Se o diferencial de taxa de juros for exógeno, como é tipicamente o caso relevante no Brasil, podemos ter um incentivo ao investidor disfarçar seu capital como se fosse de longo prazo mesmo quando já espera sacar no curto prazo. Prosseguimos a análise focando o impacto da capacidade de elisão dos controles pelo mercado. Incorporamos no modelo a elisão às restrições de entrada, mostrando que isto elimina a eficácia dos controles de capitais. Em verdade, as taxas do controle de capitais são determinadas pelo mercado, e então, quanto mais desenvolvido e sofisticado o mercado financeiro do país for, mais ativos substitutos e operações de engenharia financeira podem ser usados para circundar os controles. Fundamentamos nossas conclusões relatando diversas operações de elisão de controles de capitais dos anos noventa, que deixam claro a dificuldade de implementar de facto os controles de capitais. Terminamos a dissertação com uma análise econométrica sobre a duração da eficácia dos controels, via a estimação funções de reposta a impulso. Os resultados indicam que os controles de capitais têm apenas entre dois a seis meses de eficácia em restringir os influxos de capitais financeiros, corroborando a análise dos casos relatados de elisão dos controles. / [en] This thesis analyses the effectiveness of capital inflows controls in changing the size and composition of international financial flows. The major contribution is the focus on capital controls circumvention by the financial market and its limiting impacts on the effectiveness of short-run capital flows restrictions. At first, it is presented a theoretical approach to the question, discussing how it should be implemented. The model has a simple framework and considers two types of financial investors: patient and impatient. The first is more interested in long run returns, and the last gives more value for short run gains. We show that if the interest rate differential is endogenous to the controls fixation, and there is no possibility of regulations´ circumvention, then could be arranged a capital entrance tax scheme that induces the long run investment option for both investors, in absence of a confidence crisis. In occurrence of a higher probability of default than expected by the agent, the investment will be reverted unless higher interest rate differential is provided. Ex-post outflows capital controls could also avoid the investment reversion, nevertheless, we do not consider it here. If the interest rate differential is exogenous, which is typically the relevant case in Brazil, we might see an incentive to the investor to rename its capital as long run even when she expects to reverse the investment in the short run. We continue the analysis focusing the impact of the capacity of capital controls elision by the market. We incorporate in the model the circumvention of the entrance restrictions, showing that it ruins the capital controls effectiveness. In fact, the taxes of the capital controls are really determined by the market, and therefore, as more developed and sophisticated the financial market of the country is, more substitute assets and engineer financial operations can be used to circumvent the control. We underpin our conclusions describing several capital controls elisions operations in Brazil during the nineties, which make clear the difficulties of capital controls de facto implementation. We finish the dissertation with an impulse response function analyses, that indicates that the capital controls have only between two to six months of effectiveness in restricting financial capital inflows.

This dissertation covers both policy-oriented and theory-based topics in International Economics. The first two chapters cover financial policy related to the capital account, while the third chapter covers tariff policy related to the current account. The first chapter examines the theoretical value of capital controls in reducing the probability of bank runs. I develop a global game model with information-based bank runs and strategic complementarities within and between foreign and domestic creditors. My analysis appears to be the first to model the interconnectedness of foreign and domestic creditor behavior. The framework pins down the probability of a bank run and shows that a capital control can lower the probability of a domestic bank run and of capital flight. I also find that a control on outflows is relatively more effective than a control on inflows. Finally, I test the model's implications using the abnormal returns of Brazilian and South Korean bank stock prices as a proxy for the probability of bank runs. The second chapter analyzes the policy actions of Brazil and Chile between 2009 and the third quarter of 2011, when Brazil deployed capital account regulations and Chile intervened in its currency markets. I examine the effectiveness of each of these actions and the extent to which the actions of Brazil caused capital flow spillovers in the Chilean market. Consistent with the peer-reviewed literature on the subject, I find that capital account regulations had small but significant effects on the shifting the composition of capital inflows toward longer-term investment, on the level and volatility of the exchange rate, on asset prices, and on the ability of Brazil to have independence in monetary policy. Brazil's regulations did also temporarily cause an increase in capital flows into Chile. Chile's interventions did not have a lasting impact on the Chilean exchange rate or on asset prices beyond the initial announcements of the policies. In Brazil's case we thus conclude that Brazil's regulations helped the nation 'lean against the wind,' but were not enough to tame the 'tsunami' of post-crisis capital flows. The third chapter uses a computable general equilibrium (CGE) model calibrated to late nineteenth century parameters to show that protectionism alleviated the skilled wage gap. Had the U.S. chosen free trade instead of protective tariffs, wage inequality generally would have been higher in the post-bellum era. The imposition of high tariffs after the Civil War may have dampened what some economic historians believe to have been a long-term upward trend in inequality--the rising portion of the American-Kuznets' curve.

The primary aim of this research is to investigate whether the Draft Articles on the Responsibility of International Organizations (ARIO) which were completed in 2011 are an effective means of making IOs accountable for international wrongdoing. In order to determine this a hypothetical case was created based on the imaginary scenario that the IMF required its member states to eliminate capital controls as a condition for obtaining loans from the organization. This hypothetical case is argued on behalf of the borrowing states and thus the thesis in part has the form of a legal pleading. This approach was deliberately taken in order to provide a practical example of how the ARIO could be applied to any case related to the responsibility of IOs, not just the one under consideration here. The case is first used to illustrate how the ARIO might be applied in order to determine whether an IO’s conduct amounts to international wrongdoing and results in international responsibility. Secondly, the case is employed to demonstrate whether the ARIO provide remedies for parties injured as a result of international wrongdoing committed by IOs thereby bringing the latter to accountability. At the end of the investigation it is apparent that conduct such as the IMF’s fictional conduct in relation to its policy would amount to international wrongdoing by an IO in light of the ARIO and would incur international responsibility. However, in the course of applying the ARIO to this fictional case, it becomes evident that although the ARIO are effective for establishing the international responsibility of IOs, they are ineffective as a means of making them accountable for any responsibility they incur because they provide various escapes from the legal consequences for international responsibility. It is therefore concluded that IOs are free to continue to engage in international wrongdoing with impunity despite the creation of the ARIO.

China’s goal of eventually having the renminbi (RMB) be “fully convertible” necessarily requires that its capital account be fully liberated; this paper investigates the on-going changes of the implemented capital controls by China and China’s progress on liberalizing the country’s capital account. The first portion of the paper studies deviations of the covered interest parity, a common measure of capital controls. Econometrical analysis provides evidence for significant and persistent RMB/USD interest rate differentials, calculated from monthly data of 1-month yields for the sample period of 1999 to 2014. At the same time, evidence for cointegration between the onshore and offshore yield suggests that capital flows are not fully restrictive in the long run. The second portion of the paper analyzes constructed de jure capital control indices based on IMF’s AREAER documents following Chen and Qian (2015), and actual capital account flows based on China’s Balance of Payments. The constructed de jure indices quantify the intensity of changes of capital controls, capturing the gradualist style that China adopts in implementing its policies. The index reveals that China has been increasing its pace of capital account liberalization in the recent years compared to the past, and in particular, prioritizes liberalizing controls on outward FDI flows and equity securities inflows. The constructed de jure indices and the respective flows for FDI and equity securities are found to be highly correlated, implying that flows have been responsive to changes in the controls. It also indicates that prior to the restriction lift offs, the capital controls had been relatively effective.

In my dissertation, I explore the relationship between capital controls and the choice of the maturity structure of external debt in a general equilibrium setup, incorporating explicitly the role of international lenders. I look at specific types of capital controls which take the form of date-specific and maturity-specific reserve requirements on external borrowing. I consider two questions: How is the maturity structure of external debt determined in a world general equilibrium? What are the effects of date- and maturity-specific reserve requirements on the maturity structure of external debt? Can they prevent a bank run? I develop a simple Diamond-Dybvig-type model with three dates. In the low income countries, banks arise endogenously. There are two short-term bonds and one long-term bond offered by the domestic banks to international lenders. First I look at a simple model were international lending is modeled exogenously. I consider explicitly the maturity composition of capital inflows to a domestic economy. I show that the holdings of both short-term bonds are not differentiated according to date. Second, I consider international lending behavior explicitly. The world consists of two large open economies: one with high income and one with low income. The high income countries lend to low income countries. There exist multiple equilibria and some are characterized by relative price indeterminacy. Third, I discuss date-specific and maturity- specific reserve requirements. In my setup reserve requirements play the role of a tax and the role of providing liquidity for each bond at different dates. I show that they reduce the scope of indeterminacy. In some equilibria, I identify a case in which the reserve requirement rate on the long-term debt must be higher than that on the short-term debt for a tilt towards a longer maturity structure. Fourth, I introduce the possibility of an unexpected bank run. I show that some specific combination of date-and maturity-specific reserve requirements reduce the vulnerability to bank runs. With regard to the post-bank-run role of international lenders, I show that international lenders may still want to provide new short-term lending to the bank after the occurrence of a bank run.

O objetivo desse trabalho é responder quatro perguntas centrais a partir da literatura sobre os controles de capitais no Brasil: Os controles de capitais foram e têm sido eficazes no Brasil? O Brasil tem seguido o seqüenciamento proposto pelo FMI ao adotar controles de capitais? Os controles de capitais no Brasil são endógenos? A liberalização econômica favorece o crescimento econômico de um país? Para tanto, foram estudados outros casos de adoção de controles de capitais em diferentes economias, a partir da literatura existente, e a experiência brasileira com controles de capitais. A literatura empírica foi analisada com o intuito de verificar se os controles de capitais são eficazes para objetivos de política econômica ou se deve sustentar o processo de liberalização financeira, como defendido por alguns economistas mais ortodoxos. / The main goal of this work is to answer four key questions related to the capital controls in Brazil from a literature perspective: Were capital controls effective, and have they been, in Brazil? Has Brazil followed the sequencing proposed by IMF when adopting capital controls? Are capital controls in Brazil endogenous? Does economic liberalization promote economic growth to a country? For that, experiences of capital controls adoption in different economies were studied, using the international literature, as well as the Brazilian experience with capital controls. The empirical literature has been analyzed in order to verify if capital controls are effective for the main goals of economic politics or if a financial liberalization should be applied, as supported by some orthodox economists.

Cette thèse comporte trois chapitres traitant de la question de l’accumulation de réserves de change dans les pays émergents. Sous différents angles, théorique comme empirique, les trois travaux présentés analysent les motivations d’accumulation de réserves de change et testent l’utilité de ces avoirs en devises étrangères pendant la crise financière mondiale de 2009. Le chapitre 1 montre que l’accumulation de réserves résulte de l’interaction entre une forte croissance de la productivité et des frictions sur le marché financier. De plus, l’accumulation de réserves est d’autant plus efficace que les flux de capitaux privés sont contrôlés. Les gains du bien-être issus d’une utilisation combinée de réserves et de contrôles de capitaux diminuent avec le développement des marchés financiers. A l’aide d’une base de données comprenant 112 pays émergents et en voie de développement, le chapitre 2 examine la relation entre l’accumulation de réserves avant la crise de 2009 et la performance économique pendant la crise. Lorsque le ratio d’adéquation de réserves de change est calculé en point de pourcentage par rapport à la dette extérieure à court terme, la performance économique d’un pays pendant la crise est positivement corrélée avec les réserves de change d’avant la crise. Ce chapitre montre aussi les nouvelles tendances dans le comportement d’accumulation des réserves après la crise. Le chapitre 3 traite de la question des effets de bilan et le rôle des réserves change. Il montre qu’en accumulant des réserves de change, le gouvernement est en mesure stabiliser l’économie nationale, en recapitalisant le secteur privé avec ses devises ou en faisant une relance fiscale. / This thesis includes three essays on foreign reserves, crises and growth. Chapter 1 proposes a theoretical model to look at foreign reserve accumulation in fast-growing emerging economies. The demand for foreign reserves stems from the interaction between productivity growth and underdevelopment of the domestic financial market. During economic transition, foreign reserve accumulation is proved to be welfare improving as long as private capital flows are controlled. Chapter 2 is an empirical work on the role of foreign reserves during the global financial crisis. It is found that the level of reserves matters: countries with high reserves relative to short-term debt suffered less from the crisis, particularly if associated with a less open capital account. In the immediate aftermath of the crisis, countries that depleted foreign reserves during the crisis quickly rebuilt their stocks. This rapid rebuilding has, however, been followed by a deceleration in the pace of accumulation. Chapter 3 takes a political economy stance and shows how reserves can be used to stabilize the domestic economy when the private sector faces credit constraint and currency mismatch. It is argued that both a targeted lending in foreign currency or a fiscal spending financed by foreign reserves help remove the bad equilibrium. Nevertheless, these two policy tools differ in the mechanism through which they stabilize the domestic economy and in terms of the amount of foreign reserves needed.

This dissertation consists of three essays on capital controls and exchange rate regimes. The first essay, under the background of international monetary policy trilemma, empirically investigates the validity of the proposition that holding the degree of exchange rate stability constant, a decrease in capital mobility through imposition of capital controls will enhance monetary independence. Using a panel dataset covering 88 countries for the 1995-2010 period and system GMM estimation, this paper finds that 1) capital controls help improve a country’s monetary independence; 2) the effectiveness of capital controls depends on the types of assets and the direction of flows they are imposed; 3) the choice of exchange rate regime has important impact on the effectiveness of capital controls on monetary independence. The second essay examines the role of capital controls on economic growth. Conventional wisdom suggests that allowing international capital flows improves domestic investment and growth by providing extra resources through international capital market, yet the flows can be misallocated to finance speculative or low-quality domestic investments. Using a panel dataset covering 78 countries over 1995-2009, this paper finds that 1) capital control policies promote economic growth after taking into account a country’s de facto level of capital flows; 2) controls on capital inflows helps a country’s economic growth, but not controls on outflows; 3) restrictions on different asset types affect growth differently. Capital controls on equity type flows are less effective than controls on debt type flows or direct investment. The third examines the role of exchange rate flexibility on current account balances. Global imbalances have become an important issue for economists and policy makers. Greater exchange rate flexibility is often suggested as a means to achieve faster and more efficient adjustment in the current account. However, previous empirical studies show little support for this hypothesis. This essay revisits this issue with a large panel dataset and Threshold VAR model and finds that 1) the speed of the current account adjustment is higher in a regime with greater exchange rate variability; 2) some existing popular exchange rate classifications may not capture actual exchange rate variability as well as expected.
