Short-Run Pain, Long-Run Gain: Financial Liberalization and Stock Market Cycles Abstract Neoclassical theory indicates that financial liberalization reduces the cost of capital and leads to a permanent increase in equity prices. In contrast, the crisis literature links financial liberalization to large booms in borrowing and asset prices and ultimately financial collapses. This paper re-examines the impact of financial liberalization on stock market cycles and studies the dynamics between liberalization and institutional reforms. We also construct a new chronology of financial liberalization. We find that liberalization in emerging markets triggers more pronounced boom-bust cycles in the short run but more stable markets in the long run, partly because liberalization stimulates institutional reforms.

The crises of the past decades have ignited, once again, the debate on the effects of financial liberalization. Neoclassical models argue that the cost of capital declines following financial liberalization, triggering an increase in the value of firms. According to this view, the deregulation of financial markets improves the allocative efficiency of domestic investment, increasing productivity and growth. In this scenario, financial liberalization should be followed by a significant boom in financial markets, but not by a large crash. This view is supported by a number of recent papers in the finance literature. For example, Bekaert, Harvey, and Lundblad (2005a, 2005b) find that liberalization leads to a persistent surge in annual economic growth as well as to a decline in output volatility. Similarly, Chari and Henry (2004) and Henry (2000a, 2000b) find that liberalization triggers an increase in the investment rate and a substantial revaluation of equity prices in a large number of emerging markets. While neoclassical theory emphasizes that financial markets are efficient, a different view argues that financial markets suffer from distortions that generate anomalies in how markets allocate resources. In this context, investors may overreact to shocks, becoming optimistic and pouring capital beyond what is guaranteed by good fundamentals or withdrawing massively from countries when problems arise. These distortions can manifest when financial markets are liberalized and there is private or imperfect information, as emphasized in a number of theoretical papers, like Bachetta and van Wincoop (2000), Calvo and Mendoza (2000), and McKinnon and Pill (1997). Also, capital market imperfections are thought to be more pervasive under the presence of inadequate government institutions as well as weak supervision and regulation of the financial system. In his presidential address to the American Finance Association, Stulz (2005) concludes that when property rights are not guaranteed and expropriation risks are significant, agency problems arise and ownership concentration increases. 1
This limits economic growth and financial development, with financial deregulation leading to capital flight and crises. Supporting these views, several papers find empirical links between financial deregulation, boom-bust cycles, and banking and balance-of-payments crises. See, for example, Corsetti, Pesenti, and Roubini (1999), Demirguc-Kunt and Detragiache (1999), Kaminsky and Reinhart (1999), and Tornell and Westermann (2005). The observations that financial liberalization, despite its potential benefits, is followed by crises and that weak institutions distort the functioning of the financial system has generated a growing interest on the sequencing of financial liberalization and institutional reforms. One view argues that, protected from outside competition, badly regulated and supervised banks do not have the pressure to run efficiently. Liberalization in this scenario unveils a new problem as protected domestic banks suddenly get access to new sources of funding. Moreover, as Hellman, Murdok, and Stiglitz (2000) argue, the competition induced by financial liberalization lowers bank profits, erodes banks’ franchise values, and diminishes their incentives for making good loans, accentuating moral hazard problems. Liberalizations, thus, might trigger excessive financial booms and crashes, particularly in financially repressed countries with banks running poor balance sheets. In these cases, sequencing is advised. For example, Radelet and Sachs (1998) and Stiglitz (2000) argue that improvements in property rights as well as government accountability and transparency should precede the deregulation of the financial industry to avoid subsequent financial crises. More generally, a standard recommendation is to first upgrade the regulation and supervision of financial markets, improve the health of the financial system, and create a legal framework that enables the writing of private financial contracts; then deregulate the industry and open up the capital account.1 Since there is general agreement that in 1 See, for example, Johnston and Sundararajan (1999) and McKinnon (1993), as well as the advice by the then IMF Managing Director Michel Camdessus (Financial Times 1998). 2
industrial countries property rights are better enforced and government institutions are better run, there is typically no opposition to financial deregulation in those economies. But this type of sequencing is often recommended to developing countries, especially to the ones that are not yet fully open. A different view challenges the idea that reform should precede liberalization. According to this alternative perspective, it is not clear whether governments face incentives to promote reforms in countries with repressed financial sectors. Well-established interest groups will oppose those reforms that would eventually undermine their incumbent advantage. Therefore, financial liberalization should precede reforms, as it creates competition that leads to improvements in property rights, transparency, and the overall contractual environment. This view is expressed in recent work. For example, Rajan and Zingales (2003a,b) study the experience of twenty-four countries over a century, and find that trade openness is positively related to financial development as it fuels the political will to undertake actions that guarantee investor protection and change the legal system to help enforce contracts. Stulz (1999) and Mishkin (2003) also claim that financial liberalization and globalization help to discipline policymakers, who might be tempted to exploit an otherwise captive domestic capital market. Moreover, they suggest that the integration of emerging economies with international financial markets by itself may help to fortify the domestic financial sector, as foreign investors have overall better skills and information and can thus monitor management in ways local investors cannot. Furthermore, Stulz (2005) argues that by opening borders, financial globalization provides the means and incentives for corporate insiders to better protect minority investor rights. 3
In this paper we analyze the different effects of financial liberalization by studying its short- and long-run effects and its relation with institutional reforms. This analysis sheds new light on the arguments discussed above. Namely, the intrinsic dynamics between financial liberalization and government and corporate reform may be the key to explain the distinct findings in previous empirical work on the effects of financial deregulation. Liberalization may trigger excessive borrowing and ultimately financial collapse in the short run, as badly run and protected financial institutions gamble for resurrection in the newly open financial system. But deregulation sows the seeds of the destruction of the old protected system, with capital markets becoming more stable and promoting productivity gains in the long run as institutions improve. Our study builds up on the work pioneered by Henry (2000a), which studies the behavior of equity prices around the time of the opening of stock markets to foreign investors, and on the research initiated by Bekaert and Harvey (2000), who construct a detailed chronology of financial liberalization with a focus on stock markets. There are five primary contributions of our research to the existing research. First, we characterize the cycles in stock markets around the time of deregulation. The study of cycles is important because the literature argues that large booms and busts in financial markets are at the heart of the crises that occur following financial liberalization. Second, the previous analysis does not concentrate on the possible time-varying effects of liberalization.2 This is instead the focus of our paper. Third, we also examine the dynamics of reforms and liberalization using a variety of measures on the quality of institutions, as well as data on the laws governing the proper functioning of financial systems. As far as we know, this is the first paper to study empirically the relation among these variables. Fourth, while previous work focuses on emerging markets, we also include as a benchmark fourteen 2 Henry (2000a) analyzes the eight-month window leading up to the implementation of a country’s initial stock market liberalization. 4
mature economies. Fifth, existing papers tend to study the effects of the opening of the stock market to foreign investors. But financial liberalization can take many forms. We thus look at financial liberalization from a broader perspective. We construct a novel data set on financial deregulation that includes the opening of the stock market to foreign investors as well as the deregulation of the domestic financial sector and the opening of the capital account in twenty- eight emerging and mature markets since 1973. This database complements the well-known chronologies by Bekaert and Harvey (2002), Quinn and Inclán (1997), and the International Monetary Fund (IMF). We find that liberalization leads to more pronounced booms in the short run than in the long run in all countries in the sample. We also find that price appreciation is followed by larger crashes in emerging markets, which supports the view that liberalization might lead to large booms and crises. The effects are of first order: both booms and busts increase by about 35 percent following financial liberalization (even after controlling for macroeconomic fundamentals). Our findings for mature markets support the view that liberalization leads to a sustained increase in the value of firms. In this case, liberalization is followed by larger booms but not larger crashes. In fact, downturns are substantially smaller (about 20 percent smaller than before liberalization). Interestingly, if liberalization persists, financial cycles in both emerging and mature economies become less pronounced in the long run, with cycles even declining by about 20 percent from their average amplitude during financial repression. The dynamics of liberalization and institutional reform we document may help explain the above results. In the case of emerging markets, we find that only a few episodes of liberalization (18 percent) are preceded by improvements in government institutions. But financial liberalization seems to unleash government reforms. By the time liberalization is 5
completed (66 months on average after the liberalization process starts), institutional reforms have already occurred in about 64 percent of the cases. As the quality of institutions improves, financial cycles become less pronounced perhaps due to the reduction in agency and other problems. The evidence for mature economies indicates that law and order improve even before financial liberalization starts in about 50 percent of the cases, possibly explaining why liberalization is not followed on average by financial crashes. In fact, our econometric results indicate that improvements in law and order lead to a decline of up to 18 percent in the amplitude of financial cycles. The rest of the paper is organized as follows. Section I describes the new chronology on de jure financial liberalization for twenty-eight countries since 1973. Section I links our de jure measure of financial liberalization to financial cycles. Section II studies the relation between financial liberalization and the time-varying behavior of financial cycles. Section III examines the dynamics between financial liberalization and institutional reform. Section IV concludes. I. The Evolution of Global Financial Liberalization One of the most prolific areas of empirical research in international economics and finance has been that of the analysis of the effects of capital controls and financial liberalization on financial markets, investment, and growth. In spite of the great interest of several disciplines on the effects of deregulation of financial markets, the information on the evolution of de jure financial regulations is still fragmented. Information on capital account controls is mostly based on indicators published by the IMF in Exchange Arrangements and Exchange Restrictions. This publication only identifies two capital account regimes: a “no controls” regime, which includes episodes with full liberalization 6
of the capital account, and a “controls” regime, which includes both episodes with minor restrictions to the free flow of capital as well as episodes with outright prohibition of all capital account transactions. To capture the intensity of controls, Quinn and Inclán (1997) construct two variables that reflect the degree of capital account and current account openness for twenty-one members of the Organization for Economic Cooperation and Development (OECD) for 1950-88. Information on regulations of the domestic financial sector is even more fragmented. There is no institution compiling systematic cross-country information over time and researchers have constructed their own liberalization chronology. For example, Williamson and Mahar (1998) date liberalization based on the existence of credit controls, controls on interest rates, entry barriers to the banking industry, government regulation of the banking sector, and importance of government-owned banks in the financial system. Other efforts include those of Demirguc-Kunt and Detragiache (1999), who date liberalization for fifty-three countries since 1980. In that study, liberalization of the domestic financial sector is interpreted as liberalization of domestic interest rates. More recently, Bekaert, Harvey, Lundblad, and Siegel (2004) use different sources to determine the liberalization on restrictions on foreign banking. Information on the liberalization of domestic stock markets is also still partial. The International Financial Corporation (IFC) provides this information just for emerging markets. Again, this index only captures two regimes: a “liberalization” regime and a “restricted” regime. The liberalization dates are determined based on whether foreigners are allowed to purchase shares of listed companies in the domestic stock exchange and whether there is free repatriation of capital and remittance of dividends and capital gains. Bekaert and Harvey (2000) improve over the IFC measure by also including other indicators of deregulation of the stock market, such 7
as the establishment of new investment vehicles like country funds and depositary receipts. An updated version of their chronology is available in Bekaert and Harvey (2002).3 Our chronology complements these previous studies of the evolution of financial liberalization in various ways. First, our chronology includes deregulation episodes in both developed and developing countries. Most previous studies focus on emerging markets, perhaps because most concerns are associated with liberalization episodes in those countries, with even the most averse critics of capital account liberalization still supporting financial deregulation in mature markets.4 Second, our chronology deals with the deregulation in the capital account, the domestic financial sector, and stock markets. Most previous studies have tended to focus on the elimination of controls in just one particular financial sector. This focus on the opening of just one financial market may give an incomplete picture of the effects of regulation since controls in one sector can also affect the behavior of other parts of the financial system, which may or may not be directly under any type of restrictions.5 Third, our database captures the intensity of financial liberalization. Most chronologies do not tend to distinguish between different intensities of liberalization/repression.6 Since deregulation usually changes slowly, valuable 3 There is a very large related literature that studies the extent of de facto financial and economic integration from observable economic variables, not from de jure government regulations. See, for example, Frankel (2000), Obstfeld and Rogoff (2001), Bekaert, Harvey, and Lumsdaine (2002), Edison and Warnock (2003), and Obstfeld and Taylor (2003). 4 An exception is Quinn and Inclán (1997), who construct an index of current and capital account liberalization for twenty-one OECD countries. 5 This problem may be particularly important because the complete deregulation of financial systems is not accomplished in just one round and the time span between the deregulation of one market and the elimination of controls across the board takes, in most cases, several years. For example, the data show that, in the 1970s, domestic financial repression is widespread not only in emerging markets, but also in several mature financial markets. Governments start lifting the various restrictions gradually. In many cases, the liberalization reform starts in the banking sector with the deregulation of domestic interest rates. The elimination of interest rate controls not only affects the market for bank loans and deposits, but also attracts international capital flows (when these flows are not strictly prohibited). Also, the stock market flourishes as the extent of credit rationing diminishes. 6 Again, Quinn and Inclán (1997) is a clear exception. These authors construct an index of current and capital account restrictions that allows for different intensities of repression. For each transaction, they create an indicator with three values, 0, 1, 2, according to whether the transaction is allowed without restrictions, with some restrictions, or the transaction is simply prohibited. However, since the authors do not attempt to identify the exact characteristics of the intermediate regime beyond the fact that there are some restrictions, it is unclear whether this 8
information might be lost when the indicators only try to assess whether or not the liberalization has occurred.7 Finally, our database captures reversals of financial liberalization. Most previous chronologies analyze financial liberalization episodes as if they were permanent. Still, many countries have undergone several liberalization reversals, particularly following currency crises.8 A. New Measures of Financial Liberalization To construct the various measures of financial liberalization we use a wide range of sources, including information provided by both international and domestic institutions. The information comes not only from cross-country reports, but also from large number of country studies. Regarding international institutions, we use data from publications of the Bank for International Settlements, the International Finance Corporation, the International Monetary Fund, the Organization for Economic Cooperation and Development, and the World Bank. On the domestic side, we obtain data from annual reports by the central bank, the ministry of finance, and the stock exchanges of all the countries in our sample. We also use reports by the Economist’s Intelligence Unit. intermediate regime has similar characteristics across time and countries. In contrast, our chronology is based on a clearly defined indicator for each type of transaction, allowing us to compare experiences of partial liberalization across countries and time. For example, we classify international borrowing by banks and corporations as partially liberalized when banks and corporations are allowed to borrow abroad but subject to the following restrictions: reserve requirements on foreign loans are between 10 and 50 percent or the required minimum maturity of the loan is between two and five years. 7 For example, Chile introduces restrictions on capital inflows at the beginning of the 1990s. Controls are reinforced in the mid-1990s in the midst of the capital inflow episode. In 1998, under the threat of a contagious speculative attack against the Chilean peso, controls are eliminated. Similarly, domestic financial deregulation may take several years to be complete. For example, the deregulation of the domestic banking sector in Colombia is initiated in August 1974. Only in the 1980s, credit controls are finally eliminated. 8 For example, Argentina implements a broad liberalization of financial markets in 1977, which is later reversed in 1982. Again, in the late 1980s, a new wave of financial liberalization affects the domestic financial sector, the capital account, and the stock market. This time around the liberalization attempt is longer lasting. Still, again in 2001, in the midst of Argentina’s crisis, the government reintroduces controls on interest rates and restrictions on capital account transactions. 9
The new database includes twenty-eight countries since 1973.9 We classify the sample into four (mostly regional) country groupings: the G-7 countries, which are comprised of Canada, France, Germany, Italy, Japan, United Kingdom, and the United States; the Asian region, which includes Hong Kong, Indonesia, Malaysia, the Philippines, (South) Korea, Taiwan, and Thailand; the European group, which excludes those countries that are part of the G-7, and includes Denmark, Finland, Ireland, Norway, Portugal, Spain, and Sweden; and the Latin American sample, which consists of the largest economies in the region, Argentina, Brazil, Chile, Colombia, Mexico, Peru, and Venezuela. To capture the liberalization of the capital account, we evaluate the regulations on offshore borrowing by domestic financial institutions, offshore borrowing by non-financial corporations, multiple exchange rate markets, and controls on capital outflows. The first two indicators reflect restrictions on capital inflows. Restrictions on capital inflows can take various forms, with the most extreme restriction being an outright prohibition to borrow overseas. Milder controls include restrictions of minimum maturity on capital inflows and non-interest reserve requirements on foreign borrowing. To measure the liberalization of the domestic financial system, we analyze the regulations on deposit interest rates, lending interest rates, allocation of credit, and foreign- currency deposits. Since monetary authorities in emerging economies often use changes in reserve requirements to control banking credit, we also collect data on reserve requirements as additional information to evaluate the degree of restrictions imposed on the banking sector. To set the liberalization dates, we focus mainly on the first two variables, the price indicators. However, we complement that information with the regulations on the last three variables, those 9 In fact, since Hong Kong and Taiwan are part of China, the database has fewer countries. Still, for simplicity we refer to those economies as countries. 10
on quantities, to have a better grasp of the degree of repression of the domestic financial sector. Finally, to track the liberalization of stock markets, we study the evolution of regulations on the acquisition of shares in the domestic stock market by foreigners, repatriation of capital, and repatriation of interest and dividends. Part of these regulations on stock market indicators have already been documented by Bekaert and Harvey (2000) for some of the countries in our sample. For each sector, our chronology identifies three regimes: “fully liberalized,” “partially liberalized,” and “repressed.” The criteria used to determine whether the capital account, the domestic financial sector, and the stock market are fully or partially liberalized, or repressed, are described in detail in the Appendix Table 1. We established these criteria after collecting all the regulations and carefully studying the range of restrictions implemented in all the countries in the sample since 1973. We believe that these criteria characterize well the degrees of financial liberalization. The chronology of restrictions compiled for each country and sector along with the complete list of references used to construct it are described in separate Annex Tables 1 and 2, available upon request.10 Table 1 reports the dates of partial and full financial liberalization for all the countries in the sample. The first three columns of dates display the liberalization of the capital account, the domestic financial sector, and the stock market. The last two columns report dates of partial and full liberalization taking into account the three sectors analyzed. A country is considered to be fully liberalized when at least two sectors are fully liberalized and the third one is partially liberalized. A country is classified as partially liberalized when at least two sectors are partially liberalized. 10 This information is reported in Annex tables to eventually separate them from the rest of the paper to make it shorter. 11
B. Pace and Dynamics of Liberalization Figures 1-3 and Table 2 summarize the information in Table 1 by displaying the time- series and cross-sectional variation of liberalization. Figure 1 plots the index of financial liberalization in emerging and mature markets. This index jointly evaluates the liberalization of the capital account, the domestic financial sector, and the stock market. It can take values between one and three, with one indicating fully liberalized and three indicating fully repressed financial systems. As expected, mature financial markets are on average less regulated. The index for mature markets averages 1.7 over the sample, while for emerging markets, it averages 2.3. Across all regions there is a gradual lifting of restrictions, with the index of liberalization declining from an initial value of 2.5 for mature markets and 2.9 for emerging economies to one and 1.2, respectively, toward the end of the sample. Still, there is also a regional pattern in the dynamics of financial liberalization, with emerging markets suffering liberalization reversals in the early 1980s, following the debt crisis. In contrast, the pace of liberalization in mature markets, while also gradual, is uninterrupted. Figures 2 and 3 examine separately the sequencing of liberalization of the capital account, the domestic financial sector, and the stock market. Figure 2 shows the index of liberalization for each sector for both emerging and mature markets. Stock markets in developed countries are liberalized earlier, with the index for this sector oscillating around 1.5 in the early 1970s. In contrast, both the domestic financial sector and the capital account tend to be severely repressed until the early 1980s. In the early 1970s, the indexes for both sectors are on average above 2.5. Financial markets across the board are heavily repressed in developing countries in the early 1970s. But in the mid and late 1970s, many emerging economies liberalize the domestic sector and the capital account. The liberalization reform is short lived. Controls are re- 12
imposed in the aftermath of the 1982 debt crisis. Overall, restrictions in stock markets remain in place until the late 1980s when a liberalization wave occurs in Asia and Latin America. While Figure 2 provides information on the average level of restrictions in the various financial markets in the two regions, it may still mask individual country experiences. For example, a medium value of the index in one region may reflect that all the countries in that region are partially liberalized, or that some countries are fully liberalized while the rest of the countries are completely repressed. Figure 3 presents another perspective of the sequencing of liberalization across countries. This figure reports the proportion of countries with (at least) partial liberalization of the capital account, the domestic financial sector, and the stock market, again examined separately for emerging markets and mature markets. By the early 1970s, about 80 percent of stock markets in mature markets are already liberalized. In mature markets, the liberalization of the domestic financial sector also predates the opening of the capital account, with about all countries liberalizing, at least partially, the domestic financial sector by the mid 1980s. It is only in the late 1980s and the beginning of the 1990s, in part driven by the movement toward the formation of the European Monetary Union, that capital account liberalization reaches all mature markets. Liberalization follows a more volatile path in emerging markets. Only a small proportion of countries implement reforms before the early 1970s. This proportion increases in the late 1970s and then again in the mid and late 1980s. By early 1990s, all the sectors of the financial system are finally liberalized. There are two episodes of financial liberalization. The first one is in the late 1970s. In this episode, all the action centers in the domestic sector and the capital account, with the stock market continuing to be out of the reach for foreign investors. This liberalization episode ends following the debt crisis in 1982. The second wave of liberalization 13
starts in the late 1980s. This time around, basically both the domestic sector and the stock market are jointly deregulated, predating capital account liberalization that only starts in the early 1990s. Table 2 examines even further the sequencing of liberalization by analyzing the strategies and duration of liberalizations in Asia, Europe, G-7 countries, and Latin America. The top two panels show the proportion of episodes in which the capital account, the domestic financial sector, or the stock market is liberalized first. The top panel focuses on partial liberalization episodes; the panel below examines full liberalization episodes. The bottom two panels display the duration of liberalization episodes; they report the number of months from the time the first market is deregulated until liberalization is implemented in all markets. The top two panels reveal that the paths toward financial reform differ across regions. Basically all the G-7 countries deregulate the stock market first. European countries implement a somewhat mixed strategy toward deregulation, with 25 percent of the countries liberalizing the domestic financial sector first and basically all the rest deregulating the stock market first. On the other hand, Latin American countries overwhelmingly adopt liberalization of the domestic financial sector first, while Asian countries follow a mixed strategy, with some countries opting for deregulating the domestic sector first and some others focusing on the stock market first. Capital account liberalization in all Asian countries is mostly introduced at a latter stage. The bottom panels reveal that liberalization reforms take a long time to be completed. On average, 66 months elapse from the time the first market is liberalized until all markets are deregulated. It is worth noting that the time to completion of the liberalization reform is far longer in Asia than in Latin America. Finally, liberalization episodes that are first implemented in the stock market are the ones that become completed the fastest. The variety of experiences in 14
financial reforms indicates that it is important to examine not just the responses to liberalization in one particular financial market, but also the effects of the sequencing of deregulation. II. Stock Market Cycles and Financial Liberalization This section examines the effects of financial liberalization on booms and busts in stock prices. We are interested in quantifying the effects of liberalization on the amplitude of financial cycles and to examine whether these effects are of a permanent nature. To do so, we need first to identify financial cycles. There are various techniques to extract fluctuations at business cycle frequencies. The most well known are the Hodrick-Prescott (1997) filter, the Baxter and King (1995) band-pass filter, and the NBER methodology, which is associated with the official chronology of expansions and contractions in the United States. In this paper, we use the NBER methodology, which can be replicated using an algorithm that identifies local maxima subject to constraints on the minimum duration of the cycle. Importantly, before proceeding with our analysis of the effects of financial liberalization on booms and busts in stock prices, we need to check whether stock prices follow random walks. If stock prices follow random walks, as the theory of efficient markets would predict, the identified cycles using any of the filters would be spurious. Thus, using Monte Carlo simulations, we first test that that the random walk does not capture the basic properties of our data on stock prices. Since we reject the random walk hypothesis at all conventional significance levels, we continue with our study of the characteristics of stock price cycles in the twenty-eight countries in the sample. The description of the methodology, the identification of the cycles for each country in the sample, and the tests against the random walk hypothesis are described in Appendix I. 15
A. Characteristics of Stock Market Cycles This section examines the characteristics of stock market cycles for the various regions. We identify 146 cycles with an average duration of about 44 months. Figure 4 shows the characteristics of the typical cycle in the Asia, Europe, G7, and Latin America. The top panel reports the mean amplitude and duration of booms and crashes in the four regions, while the bottom panel plots the typical cycle in each region. The horizontal axis in the bottom panel shows the number of months before and after the peak of the cycle. The horizontal axis contains 26 months for expansions and 18 months for contractions. These are the durations of the two phases for the typical cycle in our sample. The vertical axis reports the value of the stock index. To obtain the typical cycle, the value of the stock index in each cycle is normalized to 100 at the peak. Each line in this panel represents the average value of the stock index during the 44 months around the peaks of the four regions. Cycles are more pronounced in Latin America. On average, the amplitude of cycles in this region is about twice as large as the amplitude of cycles in the G-7 countries. As expected, the most developed countries, the G-7, have milder stock market cycles, with the Asian and the other European stock market cycles being of intermediate magnitudes. We now turn to the analysis of the effects of liberalization on the characteristics of financial cycles. To examine the conflicting views on the effects of financial liberalization, we compare the characteristics of financial cycles in the short and long run, following the deregulation of financial markets. Our first approach is in the event study tradition, analyzing the behavior of stock markets in the aftermath of liberalization relative to their functioning in repression times, those years before deregulation occurs. We then report regression results that control for other factors and study the sequencing of the openings. Those results examine 16
whether liberalization creates larger cycles when the first market opens or whether each consecutive opening triggers substantial increases in booms and crashes. The regressions also test whether large financial cycles are just the product of liberalization episodes that start with opening first the capital account, the domestic sector, or the stock market. B. Event Studies Figure 5 examines the characteristics of financial cycles around the time of the overall partial liberalization of financial markets, that is, when at least two sectors are partially liberalized. We classify financial cycles in three categories, those that occur during repression times, those that occur in the short run after liberalization, and those that occur in the long run following liberalization. The short run is defined as the four years after liberalization. The long run includes the fifth year after liberalization and the years thereafter, conditional on the deregulation not being reversed.11 The top panel in Figure 5 shows the average amplitude of booms and crashes for all countries in our sample during repression times (the striped bars), in the short run following liberalization (the white bars), and in the long run after liberalization (the gray bars). It also reports the characteristics of cycles separately for emerging and mature markets since the evidence from these two groups of countries might differ. The bottom panel examines whether the differences of amplitudes across regimes are statistically significant. The evidence for the twenty-eight countries in the sample indicates that the amplitude of booms substantially increases in the immediate aftermath of liberalization (about 20 percent higher than during repression times). But equity markets stabilize in the long run if liberalization persists, with the amplitude of booms about 25 percent smaller than in repression times. 11 Since the choice of the short-run window is ad-hoc, we also examined the robustness of the results to different definitions of window size. The results for three- and six-year windows are quite similar. 17
Similarly, the amplitude of crashes increases in the immediate aftermath of liberalization (about 15 percent higher than during repression times), but declines to about 60 percent of its size during repression times if liberalization persists in the long run. As shown in the bottom panel, these differences are statistically significant at conventional levels. The evidence for the twenty-eight countries, however, obscures important differences across emerging and mature markets. The short-run effects of liberalization in emerging markets are more pronounced, with booms and crashes in the immediate aftermath of liberalization increasing by about 35 percent over their size during repression. Still, if liberalization persists, financial cycles become less pronounced, with booms about 30 percent smaller than during repression times, and crashes about 90 percent of their size during repression times. On the other hand, the evidence from mature markets indicates that if liberalization triggers more volatile stock markets in the short run, booms and busts do not increase as much as in the case of emerging markets. Moreover, on average, crashes do not increase relative to their value during repression times. Still, liberalization seems to generate more stable financial markets in the long run, with crashes averaging only about 60 percent of their size in repression times. C. Accounting for Domestic and External Shocks While the evidence in Figure 5 suggests that financial liberalization influences the size of expansions and contractions in financial markets, stock price fluctuations also reflect changes in other market fundamentals. For example, stock prices respond to expansions and recessions in the domestic economy. They also react to world economic conditions.12 The omission of these variables may bias our results, especially since the timing of liberalization may also be affected 12 For example, Calvo, Leiderman, and Reinhart (1993) argue that decreases in U.S. interest rates trigger large capital flows to emerging markets, which in turn fuel increases in asset prices. 18
by these factors. In fact, as described in Section I, Latin American countries reintroduce controls on domestic interest rates and credit and re-impose controls on capital flows following the hikes in interest rates in industrial countries in the early 1980s. Also, many emerging markets liberalize their financial markets before international capital flows increase, as in the late 1980s. Insofar as countries react to “bad times” by adopting capital controls and to “good times” by relaxing them, there is the danger that we may ascribe the increase in the size of booms to liberalization and the amplification of crashes to capital controls, when in fact it is the world market condition the one fueling changes in stock prices. To account for these factors, the event study analysis is complemented with regressions that control for domestic and world economic conditions. In particular, we examine the role of growth in domestic and world economic activity and changes in world real interest rates. We estimate the following equation by least squares with heteroskedastic-consistent standard errors, amplitudei = α ' Χ i + ρ1d ir + β1d isr + λ1d ilr + ε i , (1) where amplitudei is the amplitude of expansion (contraction) i. Χi is a matrix of control variables that includes the change in world real interest rate, the world output growth, and the domestic output growth during each expansion (contraction). d ir is a dummy variable equal to one if the cycle occurs during “repression” times, and zero otherwise. d isr is a “short-run” dummy variable equal to one if the cycle occurs in the immediate aftermath of financial liberalization (four-year window), and zero otherwise. d ilr is a “long-run” dummy variable equal to one if the cycle occurs after four years have elapsed from the time of financial liberalization, and zero otherwise. The world real interest rate is proxied with the U.S. federal funds real interest rate, world output is the average of the industrial production indexes of the G- 19
3 countries, and domestic output is captured by the index of industrial production in the domestic economy. All data come from the IMF’s International Financial Statistics. The results from this estimation are shown in Table 3. As in Figure 5, this table examines the effects of overall partial financial liberalization (when at least two sectors have been partially liberalized). As expected, fluctuations in the world interest rate affect stock market cycles and output growth, with a one percentage point increase in the world real interest rate leading to a five percentage point contraction in the amplitude of stock market expansions. Similarly, booms and crashes in stock markets are also explained by upturns and recessions in the domestic economy. Even after accounting for these other determinants of fluctuations in stock prices, financial liberalization still matters. Financial liberalization triggers larger cycles in the short run and stabilizes financial markets in the long run. Once we control for the state of the economy (domestic and foreign) and for interest rate fluctuations, the short-run effects of financial liberalization become even more pronounced. For example, in the immediate aftermath of liberalization, booms increase by about 40 percent in emerging markets and by 55 percent in mature markets relative to repression times. Similarly, crashes in emerging markets increase by 30 percent in the immediate aftermath of liberalization vis-à-vis repression times. Note that the results in Figure 5 and Table 3 suggest two different patterns in the aftermath of liberalization. While larger booms follow liberalization in both emerging and mature markets, it is only in emerging markets that crashes are more severe following liberalization. The average short-run experience in emerging markets seems to support the evidence from the crisis literature that concludes that liberalization is associated with excessive financial booms and crashes. Liberalization episodes do not seem to bring (on average) this short-run pain to mature markets. In those economies, larger booms are not followed by larger 20
crashes, suggesting that larger booms may just reflect the reduction in the cost of capital once deregulation takes place, as the neoclassical theory indicates.13 Still, financial liberalization is related to more stable financial markets in both emerging and mature market economies in the long run. D. Sequencing of Liberalization So far we have studied the liberalization across all markets. Now we turn to examine whether the short-run increase in boom-bust amplitudes occurs every time a new sector is deregulated and whether the sequencing of the openings matters. Table 4 examines whether the short-run increase in booms and busts occurs every time a new sector is deregulated. We limit our search to the deregulation of the first two sectors. We define repression times as those episodes in which all sectors are closed. The short-run liberalization periods are the four years after the opening of the first sector and the four years after the opening of the second sector. The long-run liberalization episode includes the fifth year after the opening of the second sector and the following years if the liberalization reform is not reversed. We estimate the following regression, amplitudei = α' X i + ρ1d ir + β1d isr ,1, 2 + β 2 d isr , 2 + λ1d ilr , 2 + ε i . (2) The new variable d isr ,1, 2 is a dummy variable equal to one if the cycle occurs in the immediate aftermath of financial liberalization (four-year window after the first sector is deregulated and four-year window after the second sector is deregulated), and zero otherwise. d isr , 2 is a dummy variable equal to one if the cycle occurs in the four years after the deregulation of the second 13 As always averages may hide exceptions, Denmark, Finland, Norway, and Sweden suffer financial collapses and banking crises in the early 1990s following liberalization. 21
sector, and zero otherwise. d ilr , 2 is a dummy variable equal to one if the cycle occurs after four years have elapsed from the time of the liberalization of the second sector, and zero otherwise. Thus, the average amplitude of booms (crashes) in the aftermath of the first opening is captured by β1 , while that of the second market opening is captured by β1 + β 2 . While the evidence on short-run and long-run effects of financial liberalization is not reversed, the focus on the first and second openings reveals some important differences. The increase in the amplitude of booms is similar following the first and second opening, but crashes in the immediate aftermath of the first opening are smaller than those observed during repression times. The amplitude of crashes in emerging markets only increases following the opening of the second sector. Again, this evidence is consistent with the results from the crisis literature, which finds that booms of credit persist for several years following the deregulation of financial markets with these booms in turn fueling protracted bull markets. Table 5 examines the effects on financial markets of various types of sequencing of the deregulation process. We estimate the following regression, amplitudei = α' X i + ρ1d ir + β1d isr ,1, 2 + β 2 d isr , 2 + β 3d iCA + β 4 d iSM + λ1d ilr , 2 + ε i . (3) The variables d iCA and d iSM capture the possible differential effect on booms and crashes from opening respectively the capital account and the stock market first. These dummy variables are equal to one if the cycle occurs during the four years after that particular sector is liberalized, and zero otherwise. The average amplitude of booms (crashes) in the aftermath of the first opening, when the liberalization reform is initiated with the deregulation of the domestic financial sector, is captured by β1 . If the liberalization reform starts with the opening of the capital account (stock market), the amplitude of booms or crashes in the four years after the first opening is captured by β 1 + β 3 (β 1 + β 4 ) . 22
Our results indicate that the ordering of liberalization does not matter in general. Opening the capital account or the stock market first does not have a different effect than opening the domestic financial sector first. But one exception exists; crashes seem to be larger in emerging markets if the capital account opens up first. This might provide some mild support to the usual claim that the capital account should be opened last. In sum, our results suggest that we gain from examining the effects of deregulation of different sectors. In particular, we find that crashes become more pronounced not at the onset of the liberalization reform but after some years have elapsed. Interestingly, the sequencing of financial liberalization does not seem to matter when evaluating the effects on financial cycles. Finally, as also shown in the previous section, the experiences of mature and emerging markets look different in the aftermath of financial liberalization. We analyze these differences next. III. Financial Liberalization and Institutional Reform In this section, we complement the results above by returning to the discussion on the links between financial liberalization and institutional reform summarized in the Introduction. The argument that liberalization should be preceded by institutional reforms may be irrelevant if the timing is such that reforms never predate liberalization, with institutional changes happening mostly as a result of financial deregulation. To shed new light on this debate, we compare the timing of financial liberalization and institutional reforms.14 To so, we collect data on the quality of institutions as well as on the laws governing the proper functioning of financial systems. The information on the quality of institutions is captured by the index of law and order. This index is published in the International Country Risk Guide (ICRG). The law sub-index assesses the 14 Chinn and Ito (2005) and Tornell, Westermann, and Martinez (2003) study at the relation between capital account liberalization and trade liberalization and find that the latter precedes the former. 23
strength and impartiality of the legal system, while the order sub-index assesses the popular observance of the law. Each index can take values from one to three, with lower scores for less tradition for law and order. To better assess the functioning of the financial system, we use information on the existence and enforcement of insider trading laws, constructed by Bhattacharya and Daouk (2002). Table 6 reports the time of improvement in the law and order index, the time when the insider trading law is passed, and the time when insider trading starts to be prosecuted. We characterize as an improvement in the quality of government institutions when the index of law and order increases by one unit and this change is maintained for at least two years. The top panel in Table 7 examines the sequencing of liberalization and reform in our sample of twenty eight countries. It shows the probabilities that financial liberalization occurs conditional on reforms having already been implemented. In particular, we look at whether reforms to institutions occur prior to the partial or full liberalization of the financial sector. If governments improve the quality of institutions prior to start deregulating the financial sector, one would expect the probability of partial liberalization conditional on improvements in institutions to be close to one. In contrast, if liberalization triggers reforms, those probabilities would be close to zero. In this case, we would also expect the probabilities of full liberalization conditional on reforms to institutions to be close to one since full liberalization on average occurs after five and a half years following the start of financial deregulation. As shown in Table 7, the dynamics between reforms and financial liberalization in emerging and mature economies differ somewhat. In the case of emerging markets, reforms to institutions occur mostly after financial liberalization starts. Institutions that protect property rights, as captured by the index of law and order, only improve in 18 percent of the cases prior to 24
the partial liberalization of financial markets. Similarly, institutions that facilitate contracting between citizens, as captured by insider trading prosecution laws, seem also to improve after financial liberalization starts. For example, while in 62 percent of the cases laws prosecuting insider trading exist prior to the start of financial liberalization, insider trading only starts to be prosecuted in 11 percent of the cases. Interestingly, both the institutions that protect property rights and those that regulate contracting improve substantially following the partial liberalization of financial markets. By the time the financial sector becomes fully liberalized (on average about five and a half years from the beginning of the deregulation episode), law and order have improved in 64 percent of the cases and insider trading prosecution is now enforced in 44 percent of the cases. This evidence casts doubts on the notion that governments in emerging markets tend to implement institutional reforms before they start deregulating the financial sector. On the contrary, the evidence suggests that liberalization fuels institutional reforms as suggested by Mishkin (2003) and Stulz (1999 and 2005). The dynamics between reforms and financial liberalization is different in mature economies. By the time that financial liberalization starts, institutions that protect property rights are already in place in 44 percent of the cases. In contrast, reforms that regulate contracting between citizens are not in place when liberalization begins. In only 17 percent of the cases prosecution of insider trading is implemented prior to the partial liberalization of the financial sector. In statistical terms, financial liberalization does not seem to fuel further improvements in institutions in those countries still lacking good property rights protection or prosecution of insider trading. These varied intrinsic dynamics between institutional reform and financial liberalization in developed and developing countries may be the key to explain our findings on financial cycles 25
following financial liberalization. As financial liberalization predates improvements in institutions in emerging markets, it may trigger excessive booms and busts in financial markets (in the short run) due to a variety of problems, such as the agency ones suggested by Stulz (2005). But liberalization triggers reforms and sows the seeds of the destruction of old protected financial system, with capital markets becoming more stable in the long run. In contrast, distortions in financial markets in developed economies may be less pervasive at the time of liberalization because institutional reforms precede deregulation. With more efficient financial markets, liberalization fuels increases in productivity and in the value of firms, but not financial collapses. To capture the effects of changes in institutions on financial booms and busts, we estimate the following regression, amplitudei = α ' Χ i + ρ1d ir + β1d isr + λ1d ilr + τ 1d iL & O + τ 2 d iITA + τ 2 d iITE + ε i . (4) This regression is the same as regression (1) but also evaluates the possible effects of changes in government institutions. d iL & O is a dummy variable equal to one if the boom (crash) occurs when the law and order index has improved or is at its highest level, and zero otherwise. d iITA is a dummy variable equal to one if the boom (crash) occurs following the approval of the law prosecuting insider trading, and zero otherwise. d iITE is a dummy variable equal to one if the boom (crash) occurs when insider trading prosecution is enforced and zero otherwise. The results reported in the bottom panel in Table 7 indicate that improvements in law and order do indeed trigger more stable financial markets, with the amplitude of booms and crashes declining about 18 and 9 percentage points (respectively) following government reforms.15 This result suggests one possible explanation to why mature markets, with better government 26
institutions, do not experience the larger crashes observed in emerging markets in the aftermath of liberalization. In contrast, insider trading laws (existence or prosecution) do not seem to have any impact on the amplitude of financial cycles. Our findings on the effects of various types of institutions on financial cycles support the Acemoglu and Johnson (2003) hypothesis that the role of contracting institutions is of a more limited nature than that of property rights institutions. They argue that societies can function in the face of weak contracting institutions without first order costs, but have a much harder time dealing with a significant risk of expropriation from the government. The idea is that individuals often find ways of altering the terms of their formal and informal contracts to avoid the adverse effects of contracting institutions, but are unable to do so against the risk of expropriation. It is in those last cases, when law and order institutions are weak, that agency problems become more pervasive and, we should add, financial cycles may become more pronounced as suggested by the literature on crises. IV. Conclusions This paper makes progress on the literature on financial liberalization. First, it examines the possible time-varying effects of financial liberalization on financial markets. By analyzing the short- and long-run effects, our results help to reconcile, at least in part, the conflicting empirical evidence on the effects of financial liberalization. Our estimations explain both the link between liberalization and crises as well as the relation between deregulation and financial market development. Second, it provides new empirical evidence on the dynamics of government institutional reforms and financial liberalization. The fact that reforms tend to take place after liberalization can help in understanding the short-run pain and long-run gain 15 Still, the effects on financial crashes are more imprecisely estimated that those on financial booms. 27
