This paper estimates a dynamic model of the world markets for five nonrenewable resources over the period 1970-2004 and tests for market power in each of these markets. In particular, for each nonrenewable resource, we test whether the countries supplying the nonrenewable resource behaved as price-takers or oligopolists. The results show that during the study period the world markets for copper...

We use daily price indices obtained from the Morgan Stanley Capital International to construct realized volatility for 18 individual stock markets, including the US, and the world stock market. In contrast with the CAPM, we find that volatility by itself does not forecast excess returns in most countries; however, it becomes a significant predictor when combined with the US consumptionwealth ra...

Asset prices and investment were unusually weak throughout the industrial world during the early 1990s. This paper highlights this stylized fact, and connects it with another: in most of the industrial world, asset markets boomed for several years before collapsing around 1989. The paper suggests that asset market bubbles during the late 1980s may have left the industrial world with an ‘asset m...

Emerging markets provide a formidable challenge to current asset pricing theory. The reason that emerging market do not obey standard asset pricing paradigms can be traced to the lack of complete market integration of many of these markets. Importantly, to understand both the cross-section of expected returns as well as the evolution of expected returns through time in these markets, it is nece...

It is commonly argued that China’s financial markets are effectively insulated from the rest of the world. To see if this is true and to better understand China’s financial development, we analyze China’s integration with major financial markets. Using conditional copulas, we show that China has experienced an increasing level of integration with several major financial markets during the last ...

We propose a conditional measure of capital market integration that allows us to characterize both the cross-section and time-series ofexpected returns in developed and emerging markets. Our measure, which arises from a conditional regime-switching model, allows us to describe expected returns in countries that are segmented from world capital markets in one part of the sample and become integr...

We analyze whether merger policy will be used to create global players, i.e. firms that are more competitive in world markets. In a model where firms in two countries serve their respective domestic markets plus a world market, we consider when a cost-reducing merger will be beneficial for the firms, the home country, and the world as a whole. National merger policies will generally be too rest...
