Measuring international economic linkages with stock market data
The covariance between domestic and foreign equity return innovations is decomposed into components associated with news about future real and financial variables. In an application to fifteen national stock markets, we find that news about future dividend growth tends to be more highly correlated than contemporaneous output measures, suggesting that there are lags in the international transmission of real economic shocks. In addition, results from a longer sample period suggest that both real and financial linkages between the U.S. and the U.K. appear to have increased after the Bretton ...

Strategic returns to international diversification: an application to the equity markets of Europe, Japan, and North America
We undertake a decomposition of the risk factor loadings of fifteen national stock market returns from 1972 to 1990, using a variant of the Campbell-Shiller (1988) linearization. We find considerable variation among countries in the relative importance of a cash flow component and a discount rate component in determining the beta with the world equity index return and with other risk factors. Also, the international heterogeneity we find in factor loadings suggests that a global portfolio allows substantial hedging opportunities, presumably deriving from differences in underlying economic ...
