We study the dynamics of gains from sectoral versus geographic diversification and relate economic sources to changes in those gains. We estimate conditional correlations between returns on the U.S. equity market and 16 equity markets and 10 local industries from other OECD countries and find...

International asset pricing models suggest that barriers to portfolio flows and availability of market substitutes affect the degree and time variation of world market integration. We construct diversification portfolios for eight emerging markets over the period 1976-2000, use GARCH-M...

We provide new evidence on the pricing of exchange risk in the global stock markets. We conduct empirical tests in a conditional setting for ten developed markets and twelve emerging markets to determine whether emerging market currency risk affects emerging market equities and if it spills over...

We analyze the impact of both Purchasing Power Parity (PPP) deviations and market segmentation on asset pricing and investor's portfolio holdings. The freely traded securities command a world market risk premium and an inflation risk premium. The securities that can be held by only a subset of...

Recent empirical studies have documented the dramatic growth of privatizations globally and the resultant efficiency gains. We develop a theoretical model that incorporates the costs and benefits of privatization as complex options. This framework allows us to highlight the impact of...

A simple asset pricing model is developed to take into account two important characteristics in global investments: market segmentation and noise trader risk. Our results show the removal of international investment barriers and cross-border listings have not led to a fully integrated...

While theoretical models predict a decrease in the cost of capital from depositary receipt offerings, the economic benefits of this liberalization have been difficult to quantify. Using a sample of 126 firms from 32 countries, we document a significant decline of 42% in the cost of capital. In...
