Testing the hypothesis that international equity market correlation increases in volatile times is a difficult exercise and misleading results have often been reported in the past because of a spurious relationship between correlation and volatility. This paper focuses on extreme correlation, that is to say the correlation between returns in either the negative or positive tail of the multivariate distribution. Using “extreme value theory ” to model the multivariate distribution tails, we derive the distribution of extreme correlation for a wide class of return distributions. Using monthly data on the five largest stock markets from 1958 to 1996, we reject the null hypothesis of multivariate normality for the negative tail, but not for the positive tail. We also find that correlation is not related to market volatility per se but to the market trend. Correlation increases in bear markets, but not in bull markets.

Using high-frequency data on deutschemark and yen returns against the dollar, we construct model-free estimates of daily exchange rate volatility and correlation that cover an entire decade. Our estimates, termed realized volatilities and correlations, are not only model-free, but also approximately free of measurement error under general conditions, which we discuss in detail. Hence, for practical purposes, we may treat the exchange rate volatilities and correlations as observed rather than latent. We do so, and we characterize their joint distribution, both unconditionally and conditionally. Noteworthy results include a simple normality-inducing volatility transformation, high contemporaneous correlation across volatilities, high correlation between correlation and volatilities, pronounced and persistent dynamics in volatilities and correlations, evidence of long-memory dynamics in volatilities and correlations, and remarkably precise scaling laws under temporal aggregation.

Outside the U.S. and the U.K., large corporations usually have controlling owners, who are usually very wealthy families. Pyramidal control structures, cross shareholding and super-voting rights let such families control corporations without making a commensurate capital investment. In many countries, a few such families end up controlling considerable proportions of their countries ’ economies. Three points emerge. First, at the firm level, these ownership structures, because they vest dominant control rights with families who often have little real capital invested, permit a range of agency problems and hence resource misallocation. If a few families control large swaths of an economy, such corporate governance problems can attain macroeconomic importance – affecting rates of innovation, economy-wide resource allocation, and economic growth. If political influence depends on what one controls, rather than what one owns, the controlling owners of pyramids have greatly amplified political influence relative to

This paper explores daily, international portfolio flows into and out of 44 countries from 1994 through 1998. We find several facts concerning the behavior of flows and their relationship with equity returns. First, we detect regional flow factors that have increased in importance through time. Second, the flows are stationary, but far more persistent than returns. Third, flows are strongly influenced by past returns, consistent with positive feedback trading by international investors. Fourth, inflows have positive forecasting power for future equity returns, statistically significant in emerging markets. Fifth, the sensitivity of local stock prices to foreign inflows is positive and large. Sixth, prices seem consistent with flow persistence, in that transitory inflows impact future returns negatively.

This paper develops a method of solving the identification problem that arises in simultaneous equations models. It is based on heteroskedasticity of the structural shocks. For simplicity, I consider hetereoskedasticity that can be described as a two-regime process, and show that the system is just identified. I discuss identification under general conditions, such as more than two regimes, when common unobservable shocks exist, and situations in which the nature of the heteroskedasticity is misspecified. Finally, I use this methodology to measure the contemporaneous relationship between the returns on Argentinean, Brazilian, and Mexican sovereign bonds - a case in which standard identification methodologies do not apply.

This paper investigates to what extent globalization and regional integration lead to increasing equity market interdependence. I focus on the case of Western Europe, as this region has gone through a unique period of economic, financial, and monetary integration. More specifically, I quantify the magnitude and time-varying nature of volatility spillovers from the aggregate European (EU) and US market to 13 local European equity markets. To account for time-varying integration, I allow the shock sensitivities to change through time by means of a regime-switching model. I find that these regime switches are both statistically and economically important. While both the EU and US shock spillover intensity has increased over the 1980s and 1990s, the rise is more pronounced for EU spillovers. In most countries, shock spillover intensities increased most strongly in the second half of 1980s and the first half of the 1990s. Increased trade integration, equity market development, and low inflation are shown to have contributed to the increase in EU shock spillover intensity. Finally, I find some evidence for contagion from the US market to a number of local European equity markets during periods of high world market volatility.

This paper analyzes the integration process of European equity markets since the 1980s. Its central focus is on the role that EMU, and specifically, changes in exchange rate volatility, has played in this process of financial integration. Building on an uncovered interest rate parity condition to measure financial integration, a trivariate GARCH model with time-varying coefficients yields three key results: first, European equity markets have become highly integrated only since 1996. Second, the Euro area market has gained considerably in importance in world financial markets and has taken over from the US as the dominant market in Europe.And third, the integration of European equity markets is in large part explained by the drive towards EMU, and in particular the elimination of exchange rate volatility and uncertainty in the process of monetary unification.

We characterize the response of U.S., German and British stock, bond and foreign exchange markets to real-time U.S. macroeconomic news. Our analysis is based on a unique data set of highfrequency futures returns for each of the markets. We find that news surprises produce conditional mean jumps; hence high-frequency stock, bond and exchange rate dynamics are linked to fundamentals. The details of the linkages are particularly intriguing as regards equity markets. We show that equity markets react differently to the same news depending on the state of the economy, with bad news having a positive impact during expansions and the traditionally-expected negative impact during recessions. We rationalize this by temporal variation in the competing “cash flow ” and “discount rate ” effects for equity valuation. This finding helps explain the time-varying correlation between stock and bond returns, and the relatively small equity market news effect when averaged across expansions and recessions. Lastly, relying on the pronounced heteroskedasticity in the high-frequency data, we document important contemporaneous linkages across all markets and countries over-and-above the direct news announcement
