Which exchange rate regimes in an era of high capital mobility?☆

This paper asks what influence increasing capital mobility has on the choice of exchange rate regime. Among exchange rate regimes considered are currency boards and dollarization. It is argued that a key lesson of the recent currency and financial crises in the emerging markets is that corner solutions in exchange rate policy may be preferable to less rigidly fixed exchange rates. The paper concludes that in the end the optimal exchange rate regime depends on the circumstances of a particular country and time, because each exchange rate system requires the fulfillment of certain preconditions. The paper then discusses institutional measures and innovations that may be necessary to enable exchange rate arrangements to avoid financial and currency crises or to dampen their consequences.     

An Exegesis on Currency and Banking Crises

Abstract.  This paper reviews the literature on currency and banking crises. Currency and banking crises are characterized according to some standards in the literature and their historical record summarized. The development of the literature from first through fourth‐generation, or so‐called 'institutional' models is reviewed. A digression on institutions is provided along with some sidebars on the development of the literature on institutions as it relates to economic growth. The empirical research on third‐generation (or twin crises) models and on institutional models of currency and banking crises, which are so far scarce, is covered too. A summary of the main policy issues for dealing with financial crises is presented. The paper closes with an emphasis on institutions and a call for more research directed at institutions and their role in the financial system.     

Government bailouts and monetary disequilibrium: common fundamentals in the Mexican and East Asian currency crises

Monetary disequilibrium seems to be a common thread that connects the Mexican and East Asian crises. Both crises have been characterized by governments attempting to minimize the adverse impacts of capital reversals on their domestic financial systems. This backstopping function of the monetary authority is modeled within an escape clause-based currency crisis framework which emphasizes the “nonmechanical” behavior of governments as they trade off various economic policy objectives.     

Second Generation Models of Currency Crises

Until the beginning of the 1990s, currency crises were typically analyzed within the framework of a generation of models that assumed that the foreign exchange reserves of a country that was running a fixed exchange rate policy were falling (because the government was running a deficit on its budget that was financed by printing money). When the foreign exchange reserves reached a lower bound, a speculative attack on the fixed exchange rate was launched. Today, this theory is no longer the benchmark when explaining the occurrence of a currency crisis. Actually, a new generation of models that seeks to take explicitly into account the costs and benefits associated with the maintenance of a fixed exchange rate has emerged. This paper surveys these 'second generation models of currency crises'. This generation of models emphasizes that it is an endogenous decision if a government chooses to abandon a policy of fixed exchange rates. The survey pays special attention to the fact that the second generation of currency crises models often generates multiple equilibria for the rate of devaluation given one state of the economic fundamentals. A currency crisis can thus occur even if no secular trend in economic fundamentals can be identified, as in recent currency crises.     

Value-at-Risk (VaR) Computations Under Various VaR Models and Stress Testing

SUMMARY

Bank for International Settlements (BIS) proposes that all banks calculate and report amount of market risk they incur and allocate sufficient amount of capital starting at the beginning of year 2002. BIS also suggests that value-at-risk (VaR) models in computing market risk should be used. The Turkish Bank Regulation and Supervision Agency already required all Turkish banks to compute and periodically report market risk and reserve adequate amount of capital since January, 2002. This study mimics an average trading marketable securities portfolio subject to market risk of the four largest Turkish banks. The publicly available quarterly financial reports of year 2001 for Isbank, Garanti, Yapi Kredi and Akbank are examined, and a mimicking portfolio composition is determined as bond investments; 60% in Turkish currency (TRL), 20% in American dollar (USD) and 20%in Euro (EUR). The VaR amounts of the mimicking portfolio are computed by applying Historical Simulation, Monte Carlo Simulation, Delta-Normal and Standard Methods. Finally, stress test is applied for each of the models by using crisis scenarios. The Turkish financial crises of November 2000 and February 2001 are simulated as stress scenarios. The results of stress testing reveal that all methods except standard method can stand the crisis in November 2000, but none of the models can stand the crisis in February 2001.     

Quantity of finance and financial crisis: A non-monotonic investigation☆

Whether finance is beneficial to economic development remains ambiguous. There are studies arguing that finance can facilitate growth and increase stability. However, the recent global financial crisis has led some to argue that finance can decrease stability and lead to more crises. This paper constructs a non-monotonic framework of quantity of finance (measured by leverage) and financial crisis and decomposes leverage into fundamental and excess components. Using cross-country level data, the empirical results confirms that it is excess leverage, rather than fundamental leverage, that results in the increase of probability of financial crisis. Further empirical results show that excess leverage leads to a higher probability of currency crisis, asset price collapse, and banking crisis, while fundamental leverage helps alleviates the crises. This paper reconciles the two contrasting views of the relationship between finance and economic development and provides strong policy implication to pay special attention to the sudden increase of leverage, which is probably excessive, rather than fundamental leverage.     

Crises, portfolio flows, and foreign direct investment: An application to Turkey

We analyze how financial and economic crises affect the relation between the components of capital flows and their determinants in an emerging economy. Our results suggest that the composition of capital flows matters, crises can explain the volatility of portfolio flows and foreign direct investment, and modeling them as endogenous breakpoints improves the results considerably. By using data from the Turkish economy, we estimate these breakpoints together with the parameters of the model and find that they correspond to international and domestic crises that hit the country. Although both components are affected by similar crises, direct investment reacts strongly to the domestic crisis, while portfolios flows are more sensitive to global financial conditions. Breaks also have an effect on the significance and sign of determinants of each type of international investment. Evidence indicates changes in all coefficients in both investment types and suggests that analyses assuming parameter constancy lead to misleading results if they ignore the influence of endogenous breaks.     

Forecasting leadership transitions around the world

We use popular non-parametric (CART, TreeNet) and parametric (logit) techniques to identify robust economic, demographic and political conditions that lead to shifts in control in the executive branch of government in 162 countries during the period 1960–2004. We find that institutional aspects of the political system, executive characteristics, demographic variables, economic growth, and economic trade variables are all very important for predicting leadership turnover in the following year. Financial crises are not robustly useful for this purpose, but a vulnerability to currency crises in times of low economic growth implies very high conditional probabilities of job losses for democratic leaders in non-election years. In-sample, TreeNet predicts 78% of leadership transition events correctly, compared to CART’s 70%, and TreeNet also generally achieves higher overall prediction accuracies than either CART or the logit model out-of-sample.     

Network analysis of exchange data: interdependence drives crisis contagion

In this paper, we examine linear and nonlinear co-movements that appear in the real exchange rates of a group of 28 developed and developing countries. The matrix of Pearson correlation and Phase Synchronous coefficients have been used in order to construct a topology and hierarchy of countries by using the Minimum Spanning Tree (MST). In addition, the MST cost and global correlation coefficients have been calculated to observe the co-movements’ dynamics throughout the time sample. By comparing Pearson and Phase Synchronous information, a new methodology is emphasized; one that can uncover meaningful information pertaining to the contagion economic issue and, more generally, the debate surrounding interdependence and/or contagion in financial time series. Our results suggest some evidence of contagion in the Asian currency crises; however, this contagion is driven by previous and stable interdependence.     

Relative risk aversion and the transmission of financial crises

We study how investor behavior affects the transmission of financial crises. If investors exhibit decreasing relative risk aversion, then negative wealth shocks increase the risk premium required to hold risky assets. We integrate this into a second generation model of currency crises which allows for contagion through changes in fundamentals. Investor behavior can be a transmission channel of financial crises, as changes in risk premia increase the coverage ratio and makes the defense of a peg less attractive for the policy maker. The feedback effect of the risk premia on the probability of devaluation also makes multiple equilibria more likely. The possible stabilization effects of capital controls and a Tobin tax on the international transmission of financial crises are also studied.     

Modelling Currency Crises in Emerging Markets: A Dynamic Probit Model with Unobserved Heterogeneity and Autocorrelated Errors*

The paper investigates the causes of currency crises in emerging markets. We estimate the probability of a currency crisis by applying maximum smoothly simulated likelihood to a dynamic LDV model. This approach allows us to take explicit account of the existence of intertemporal links between crises. The results show that currency crises are influenced by real, monetary, debt and global variables. Past banking crises are significant determinants of the probability of currency crises. Moreover, countries that sharply devalued in the past are less prone to experience another currency crisis. We find evidence of unobserved heterogeneity, which may reflect differences in the countries’ institutional/historical background. Finally, the determinants of currency crises differ by type of exchange rate regime.     

Asymmetries between Rich and Poor Countries in Financial Crisis Responses: The Need for a Flow-of-Funds Approach

This paper focuses on the manner in which interest rates have been raised to, and sustained at, extremely high levels in developing and emerging market economies as a consequence of recent financial crises. By contrast rich market economies have typically lowered interest rates and injected liquidity in response to incipient financial crises. The paper first sketches the logic that lies behind extremely high interest rates (nominal and real) as an element of crisis resolution. It suggests that this reflects a money-phobic view of financial markets and also conflicts with some well-established economics. It then reviews the conventional wisdom about why richer economies have enjoyed sustained price stability in recent years and why this in turn has allowed their monetary authorities to be relaxed about injecting additional liquidity in response to LTCM (1998) and September 11 (2001)-type crises. It is pointed out that this conventional wisdom is also money-phobic in that it neglects the build up of corporate and government debt in bond and financial derivative form that has been associated with recent financial developments. This analysis helps to contest the common view that emerging market economies pay a higher price merely because their polices are "bad'. Finally, the paper reviews the manner in which the financial systems of developing and emerging market economies respond to the destabilization created by corrosively high real rates of interest. Even when bankruptcy arrangements are well established, certain new forms of financial flows and instruments are implicit in this response, but are invariably ignored in formal modelling.     

Structural vulnerability and resilience to currency crisis: Foreign currency debt versus export

Is there any factor that is not analyzed in the literature but is important for preventing currency crises? I argue that exports are an important factor to prevent currency crises that has not been frequently analyzed in the existing theoretical literature. Using the third generation model of currency crises, I derive a simple and intuitive formula that captures an economy’s structural vulnerability characterized by the elasticity of exports and repayments for foreign currency denominated debt. I graphically show that the possibility of currency crisis equilibrium depends on this structural vulnerability and also analyze how this vulnerability impacts the effectiveness of monetary policy response.     

On the relation between currency and banking crises in developing countries, 1980–2010

This paper investigates the relationship between the occurrence of currency and banking crises using high-frequency data for a sample of 94 countries during 1980–2010. The two types of crises are proxied by continuous, multi-categorical and dummy variables based on market pressure indexes, and a dummy variable from the Laeven–Valencia banking crises database. Results suggest that a bidirectional leading relationship exists between the two types of crises. However, banking crises do not lead currency crises robustly when banking crises are proxied by dummies based on market pressure indexes. Finally, currency crises have robust state dependence, but this is not the case for banking crises.     

The impact of ADR activity on stock market liquidity: Evidence from Latin America

This paper examines the impact of ADR activity on liquidity of four major Latin American stock markets. We construct a measure of ADR activity in U.S. markets for a sample of ADRs trading during January 2003–December 2010, which is subsequent to the financial liberalization episodes and currency crises that shocked emerging markets in the 1990s. The sample lists 164 depositary receipt programs (Levels I, II, and III): 16 from Argentina, 81 from Brazil, 19 from Chile, and 48 from Mexico. Using System GMM methods to handle the potential effects from stock market development on economic growth and ADR issuance, we find that higher ADR turnover in U.S. markets has positive effects on domestic market turnover, particularly for issuance of exchange-listed (Levels II and III) ADRs. This positive relationship is not a statistical artifact created by the global financial crisis of 2008.     

Currency depreciation effects on ADR returns: evidence from Latin America

We use seemingly unrelated regressions (SUR) and multivariate regression models (MVRM) in a panel sample of 74 American depository receipts (ADR) programs from Argentina, Brazil, Chile, and Mexico during the period May 1994 to May 2009 to analyze the behavior of ADR returns during the 300-day period surrounding the currency crises breakdown in the originator??s country. Controlling for the underlying stock and local and host country equity indices, we find that ADRs generate significant negative abnormal returns during currency crises, due to translation exposure. Abnormal returns remain statistically significant even in crises triggered by currency depreciations as small as 3.6%. The results persist after including exchange rate returns as a control variable and after an orthogonalization procedure of exchange rate against local country indices. In agreement with ADR literature, our results show that ADR prices are determined primarily by the underlying stock, exchange rates, and host country index, in that order. Moreover, we observe how market integration has become evident in more recent times as the coefficients for the U.S. stock market have increased its contribution to ADR price discovery.     

Volatility spillovers among the U.S. and Asian stock markets: A comparison between the periods of Asian currency crisis and subprime credit crisis

This paper examines the changing nature of volatility spillovers among the U.S. and eight East Asian stock markets between two financial crises: the Asian currency crisis and the U.S. subprime credit crisis. Our empirical results suggest that volatility is not always spilled over from the directly affected markets to surrounding markets in crisis periods. The East Asian markets who directly suffered from the Asian currency crisis are the ones to which volatility is spilled over from other markets during the Asian currency crisis period, whereas uni-directional volatility spillovers from the U.S. market to other markets are observed during both crisis periods. This difference can be explained by a pre-determined hierarchy in which volatility spillovers tend to start from the U.S. market regardless of the geographical origin of the crisis. Furthermore, our results reveal that the markets in three major Asian financial hubs, i.e., Japan, Hong Kong and Singapore, are the markets to which volatility is spilled over uni-directionally from several other countries during the subprime credit crisis period, but not during the Asian currency crisis period. We attribute this difference to crisis-specific (currency or credit crisis), market-specific (credit derivatives market participation and foreign currency reserves), and time-specific (more integrated global market) factors.     

Currency crisis early warning systems: Why they should be dynamic

Traditionally, financial crisis Early Warning Systems (EWSs) have relied on macroeconomic leading indicators when forecasting the occurrence of such events. This paper extends such discrete-choice EWSs by taking the persistence of the crisis phenomenon into account. The dynamic logit EWS is estimated using an exact maximum likelihood estimation method in both a country-by-country and a panel framework. The forecasting abilities of this model are then scrutinized using an evaluation methodology which was designed recently, specifically for EWSs. When used for predicting currency crises for 16 countries, this new EWS turns out to exhibit significantly better predictive abilities than the existing static one, both in- and out-of-sample, thus supporting the use of dynamic specifications for EWSs for financial crises.     

How I learned to stop worrying and love the crisis

We investigate the effects of economic crises on the subsequent economic, performance, economic reform, democratization and institutional change. Our analysis is based on a sample of post-communist countries, most of which experienced severe economic, crises during the 1990s. We find that the severity of crisis has a positive impact on the subsequent pace of economic reform, economic growth and, with a delay, on investment and institutional change. Episodes of high inflation, moreover, translate into lower subsequent inflation. Crises thus serve as catalysts of reform and institutional change and lead to better long-term economic performance.
