Stock market cycles, financial liberalization and volatility

In this paper we analyze the cycles of the stock markets in four Latin American and two Asian countries, and we compare their characteristics. We divide our sample in two subperiods in order to account for differences induced by the financial liberalization processes of the early 1990s. We find that cycles in emerging countries tend to have shorter duration and larger amplitude and volatility than in developed countries. However, after financial liberalization Latin American stock markets have behaved more similarly to stock markets in developed countries whereas Asian countries have become more dissimilar. Concordance of cycles across markets has increased significantly over time, especially for Latin American countries after liberalization.     

Financial liberalization and changes in the dynamic behaviour of emerging market volatility: Evidence from four Latin American equity markets

This paper examines whether the dynamic behaviour of stock market volatility for four Latin American stock markets (Argentina, Brazil, Chile and Mexico) and a mature stock market, that of the US, has changed during the last two decades. This period corresponds to years of significant financial and economic development in these emerging economies during which several financial crises have taken place. We use weekly data for the period January 1988 to July 2006 and we conduct our analysis in two parts. First, using the estimation of a Dynamic Conditional Correlation model we find that the short-term interdependencies between the Latin America stock markets and the developed stock market strengthened during the Asian, Latin American and Russian financial crises of 1997–1998. However, after the initial period of disturbance they eventually returned to almost their initial (relatively low) levels. Second, the estimation of a SWARCH-L model reveals the existence of more than one volatility regime and we detect a significant increased volatility during the period of crisis for all the markets under examination, although the capital flows liberalization process has only caused moderate shifts in volatility.     

Financial market interdependencies: A quantile regression analysis of volatility spillover

This paper investigates the degree and structure of interdependence between emerging (Asian and Latin American) and developed (USA and Japan) stock markets through the study of volatility spillovers for the period spanning from January 1, 1993 to October 13, 2010. Using both standard GARCH model and quantile regression approach, we find the evidence of significant interdependence between financial markets which may give evidence of volatility transmission. The volatility transmission is closely associated with geographical proximity as well as with crisis periods which confirm the presence of contagion. The analysis of upper and lower quantiles allows observing that the interdependence increases during bullish markets while decreases during bearish markets. Accordingly, the structure of interdependence is asymmetric for both Asian and Latin American emerging markets. These findings open up new insights for government policy makers as well as for managerial purposes.     

Internationalization and the capital structure of firms in emerging markets: Evidence from Latin America before and after the financial crisis

This study examines the impact of internationalization on the capital structure of firms in emerging markets before and after the financial crisis of 2008, with evidence from five countries in Latin America (Argentina, Brazil, Chile, Mexico, and Peru). We find that before the financial crisis, Latin American MNCs are characterized by lower debt levels than purely domestic firms. However, after the financial crisis, we find that the MNCs are characterized by higher debt levels. This finding suggests that after the financial crisis, the Latin American MNCs (like many firms) may be taking advantage of their access to low interest rates in the global capital markets.     

Common stochastic trends among Far East stock prices: Effects of the Asian financial crisis

This paper investigates empirically the change(s) in the long-run relationship(s) between the stock prices of eight Far East countries around the Asian financial crisis of 1997-98. Further tests are conducted to check the change in the influence of the Japanese and the US stock markets in the Far East Region before, during and after the crisis. Empirical investigation is conducted by means of rolling correlation coefficients, the Johansen multivariate cointegration method, causality tests and band spectrum regression. Results show significant long-run relationship(s) and linkage between the Far East markets before, during, and after the crisis. The most significant linkage and relationship are found during the crisis period. Results mostly indicate larger US influence in all periods but some evidence of increasing Japanese influence is also shown.     

A study of cointegration and variance decomposition among national equity indices before and during the period of the Asian financial crisis

This study uses a cointegration and variance decomposition analysis to examine the linkages among the stock markets of 12 Asia–Pacific countries, before and during the period of the Asian financial crisis. Johansen (1988) multivariate cointegration and error-correction tests demonstrate evidence in support of the existence of cointegration relationships among the national stock indices during, but not before, the period of financial crises. In the recent crisis, the relationship within the South-East Asian countries seems to be stronger than that within the North-East Asian countries. The variance decomposition reveals that the ‘degree of exogeneity’ for all indices has been reduced, implying that no countries are ‘exogenous’ to the financial crisis. In addition, Granger’s causality test suggests that the US market still ‘causes’ some Asian countries during the period of crisis, reflecting the US market’s persisting dominant role.     

The dynamics of privatization, the legal environment and stock market development

In this paper, we examine under which conditions privatization is an effective means to develop local stock markets for a panel of 61 countries over the last twenty four years. By addressing the endogeneity between privatization and stock market development, we show for the 1980-98 period that the initial legal environment is a significant contemporary determinant of stock market development, while privatization is not. When we examine the dynamics of privatization in interaction with the legal environment, we find that privatization has a two-year-lagged effect on stock market development in emerging markets, and a one-year-lagged effect in developed countries. Results for the 1999-2003 period seem to be largely affected by the global crash that followed the Asian crisis.     

Extreme observations and diversification in Latin American emerging equity markets

In this paper, we focus on the tails of the unconditional distribution of Latin American emerging markets stock returns. We explore their implications for portfolio diversification according to the safety first principle, first proposed by Roy [Econometrica (1952) 20, 431]. We find that the Latin American emerging markets have significantly fatter tails than industrial markets, especially, the lower tail of the distribution. We consider the implication of the safety first principle for a US investor who creates a diversified portfolio using Latin American stock markets. We find that a US investor gains by adding Latin American equity markets to her purely domestic portfolio. For different parameter specifications, we find a more realistic asset allocation than the one suggested by the literature based on the traditional mean-variance framework.     

US and Domestic Market Gains and Asian Investors’ Overconfident Trading Behavior

We find that subsequent to both US and domestic market gains, both Asian individual and institutional investors increase their trading and that this effect is more pronounced in bull markets, in periods of relatively favorable investor sentiment, in periods of extremely high market returns, and in markets with short‐sale constraints. We also find that individual investors trade more in response to market gains than institutional investors. Moreover, we find that further integration of Asian stock markets with US stock markets after the Asian financial crisis in 1998 is an important reason for Asian investors’ response to US market gains.     

Do controlling shareholders' expropriation incentives imply a link between corporate governance and firm value? Theory and evidence

We develop and test a model that investigates how controlling shareholders' expropriation incentives affect firm values during crisis and subsequent recovery periods. Consistent with the prediction of our model, we find that, during the 1997 Asian financial crisis, Asian firms with weaker corporate governance experience a larger drop in their share values but, during the post-crisis recovery period, such firms experience a larger rebound in their share values. We also find consistent evidence for Latin American firms during the 2001 Argentine economic crisis. Our results support the view that controlling shareholders' expropriation incentives imply a link between corporate governance and firm value.     

Herd behavior and equity market liquidity: Evidence from major markets

This paper provides new evidence on the relation between herd behavior and equity market liquidity, an issue that has been neglected when it comes to studying herd behavior towards the consensus. We use equity price data for the G5 markets, and initially find no evidence of herding. When, however, we condition on the liquidity of stocks we find significant evidence of herd behavior for high liquidity stocks, for most countries, a result robust to different definitions of the crisis period and different measures of liquidity. The only exception is Germany for which there is weaker evidence of herding in high liquidity stocks. Variance decomposition tests indicate that the variance of the average equity market liquidity is affected by return clustering, especially during the crisis and post-crisis period an effect that is more pronounced for the US market.     

Measuring financial contagion: A Copula approach

This paper models dependence with switching-parameter copulas to study financial contagion. Using daily returns from five East Asian stock indices during the Asian crisis, and from four Latin American stock indices during the Mexican crisis, it finds evidence of changing dependence during periods of turmoil. Increased tail dependence and asymmetry characterize the Asian countries, while symmetry and tail independence describe the Latin American case. Structural breaks in tail dependence are a dimension of the contagion phenomenon. Therefore, the rejection of the correlation breakdown hypothesis should not be considered, without further investigation, as evidence of a stable dependence structure.     

Momentum Strategies: Evidence from Pacific Basin Stock Markets

We investigate the profitability of momentum investment strategy in six Asian stock markets. Unrestricted momentum investment strategies do not yield significant momentum profits. Although we find that a diversified country‐neutral strategy generates small but statistically significant returns during 1981–1994, when we control for size and turnover effects we find that the country‐neutral profits dissipate. Our evidence suggests that the factors that contribute to the momentum phenomenon in the United States are not prevalent in the Asian markets.     

Institutional herding in international markets

This paper studies herding behavior of institutional investors in international markets. First, we document the existence of wide-spread herding in 41 countries (referred to as “target countries” hereafter) in the sample. We then examine the relation between contemporaneous institutional demand and future returns and find that institutional herding stabilizes prices. Next, we examine the relation between institutional investors’ herding behavior and the level of information asymmetry in the target countries. We measure the degree of information asymmetry in each target country along five dimensions: (1) stock market development, (2) ease of access to information, (3) corporate transparency, (4) investor rights, and (5) macroeconomic factors that relate to the information environment. We find evidence that institutional investors herd more in markets characterized by low levels of information asymmetry (high level of information transparency). This result suggests that institutional investors’ herding behavior is likely driven by correlated signals from fundamental information. Lastly, we show that price adjustment is faster in informationally transparent markets.     

Stock market linkages: Evidence from Latin America

This study investigates the dynamic interdependence of the major stock markets in Latin America. Using data from 1995 to 2000, we examine the stock market indexes of Argentina, Brazil, Chile, Colombia, Mexico and Venezuela. The index level series are non-stationary and so we employ cointegration analysis and error correction vector autoregressions (VAR) techniques to model the interdependencies. We find that there is one cointegrating vector which appears to explain the dependencies in prices. The results are robust to sensitivity tests based on translating indexes to US dollars (i.e., a common currency for all the markets) and to partitioning the sample into periods before and after the Asian and Russian financial crises of 1997 and 1998, respectively. Our results suggest that the potential for diversifying risk by investing in different Latin American markets is limited.     

Returns and volatility spillover in the European banking industry during global financial crisis: Flight to perceived quality or contagion?

This paper empirically investigates return, volatility and leverage spillover effects between banking industrial stock markets of the major economies (ME) (Germany, UK and US) and the smaller stressed European Union countries (SE), (Italy, Ireland, Greece, Spain and Portugal) from 2002 to 2014 which includes the global financial crisis period (2007–2014). Thus the paper investigates the influence of the global crisis on the spillover between the banking industrial stock markets of Europe and the US. We apply a multivariate GARCH–GJR framework to investigate the effects of the financial crisis with respect to spillover. Our results indicate an increase in both means and volatility spillover between the major economies and the stressed EU economies from the pre-crisis to the crisis period. During the pre-crisis period there is ample evidence of spillover from Germany, UK and the US to the smaller EU economies. Little evidence of a significant spillover from the smaller economies to the major economies is found during this period. We find that return and volatility transmission mechanisms between the major economies and the smaller EU countries are asymmetric during the crisis period. During the crisis, the level and amount of spillover from the major economies increase. But now there is also clear evidence of spillover from smaller EU economies to the major economies, this is especially true for Germany and the UK. Evidence of spillover effects suggests the existence of exploitable trading strategies and has important implications to investors in the areas of option pricing, portfolio optimization and risk management.     

Testing the fire-sale FDI hypothesis for the European financial crisis

Using a panel of corporate transactions in 27 EU countries from 1999 to 2012, we investigate the impact of the financial crisis on the market for corporate assets. In particular, we test the ‘fire-sale FDI’ hypothesis by analyzing the number of cross-border transactions, the price of corporate assets and the impact of credit and macroeconomic conditions. According to the fire-sale FDI hypothesis, countries affected by a crisis attract foreign buyers selling assets at a discount. We find a dampening effect of the crisis on cross-border transactions in all EU countries. Although countries with higher sovereign default risk and lower economic demand attracted more foreign buyers in the crisis, lower domestic credit is associated with less cross-border transactions. Corporate assets in crisis countries are cheaper, particularly if domestic credit is low; however, these findings are not limited to the crisis period. This pattern is strikingly different from the East Asian and Latin American financial crises. Overall, we find little evidence for ‘fire-sale FDI’ suggesting an integrated European market without significant frictions.     

A spatial analysis of international stock market linkages

We employ spatial econometrics techniques to investigate to what extent countries’ economic and geographical relations affect their stock market co-movements. Among the relations that we analyze, bilateral trade proves to be best suited to capture co-variations in returns. We find a strong effect of a unit shock to three regionally dominant countries, namely the US, the UK, and Japan, on other countries through the trade linkage. The degree of stock market dependence increases and the importance of proximity decreases over time and during recessions. We also analyze several regional crises and find a large impact of Thailand on its trade neighbors during the Asian crisis.     

Transmission of the financial and sovereign debt crises to the EMU: Stock prices,CDS spreads and exchange rates

This paper tests for the transmission of the 2007–2010 financial and sovereign debt crises to fifteen EMU countries. We use daily data from 2003 to 2010 on country financial and non-financial stock market indexes to analyze the stock market returns for three country groups within EMU: North, South and Small. The following results hold for both the North and South European countries, while the smallest countries seem to be relatively isolated from international events. First, we find strong evidence of crisis transmission to European non-financials from US non-financials, but not for financials. Second, in order to test how the sovereign debt crisis affects stock market developments we split the crisis in pre- and post-Lehman sub periods. Results show that financials become significantly more dependent on changes in the difference between the Greek and German CDS spreads after Lehman’s collapse, compared to the pre-Lehman sub period. However, this increase is much smaller for non-financials. Third, before the crisis euro appreciations coincide with European stock market decreases, whereas this relationship reverses during the crisis. Finally, this reversal seems to be triggered by Lehman’s collapse.
