Emerging equity markets have become increasingly interrelated over the past two decades. For a sample of thirty-two emerging markets from four different regions, we find significant positive time trends in cross-country correlations within regions, correlations across regions, and in comovements with the rest of the world. Furthermore, we examine the economic mechanisms that drive these trends. We find that official market liberalization, a continuous measure of equity market openness, equity market development, and to some extent, trade openness all play a role. However, we show important heterogeneity across regions, both in the speed at which comovements increase over time and in the underlying macroeconomic channels.

We estimate and test the conditional version of an International Capital Asset Pricing Model using a parsimonious multivariate GARCH process. Since our approach is fully parametric, we can recover any quantity that is a function of the first two conditional moments. Our findings strongly support a model which includes both market and foreign exchange risk. However, both sources of risk are only detected when their prices are allowed to change over time. The evidence also indicates that, with the exception of the U.S. equity market, the premium for bearing currency risk often represents a significant fraction of the total premium.

The authors investigate the potential for manipulation due to the interaction between secondary market trading prior to a seasoned equity offering and the pricing of the offering. Informed traders acting strategically may attempt to manipulate offering prices by selling shares prior to the seasoned equity offering, and profit subsequently from lower prices in the offering. The model predicts increased selling prior to a seasoned equity offering, leading to increases in the marketmaker's inventory and temporary price decreases. Further, sinc e manipulation conceals information, the ratio of temporary to permane nt components of the price movements is predicted to increase.

This paper uses style analysis to investigate whether Euro-zone equity returns are driven by country or industry effects over the 1990–2008 period. We find that before the introduction of the Euro, country effects dominate, while industry effects prevail after 1999. This reversal is driven mainly by the countries that were least integrated in the Economic and Monetary Union (EMU) and world markets in the early 1990s and for which the EMU convergence process led to rapid strengthening of linkages with the core Euro-zone. For markets with stronger economic linkages, industry effects dominate both before and after the introduction of the Euro.

We test the conditional capital asset pricing model (CAPM) for the world's eight largest equity markets using a parsimonious generalized autoregressive conditional heteroskedasticity (GARCH) parameterization. Our methodology can be applied simultaneously to many assets and, at the same time, accommodate general dynamics of the conditional moments. The evidence supports most of the pricing restrictions of the model, but some of the variation in risk‐adjusted excess returns remains predictable during periods of high interest rates. Our estimates indicate that, although severe market declines are contagious, the expected gains from international diversification for a U.S. investor average 2.11 percent per year and have not significantly declined over the last two decades.

We investigate the potential for manipulation due to the interaction between secondary market trading prior to a seasoned equity offering (SO) and the pricing of the offering. Informed traders acting strategically may attempt to manipulate offering prices by selling shares prior to the SO, and profit subsequently from lower prices in the offering. The model predicts increased selling prior to a SO, leading to increases in the market maker's inventory and temporary price decreases. Further, since manipulation conceals information, the ratio of temporary to permanent components of the price movements is predicted to increase.
