Abstract

In this paper, we demonstrate that time-varying investor risk aversion can generate significant state dependence in the correlation of international stock returns, despite the underlying endowment/dividend processes being i.i.d. We also find that the welfare benefits of international diversification associated with these time-varying co-movements tend to increase (rather than decrease) in states when the correlations of international stock returns are high, or when cross-market contagions appear most severe. In a world in which risk sharing among different countries is still imperfect, our findings imply that contagion-like variations in the correlation of international stock returns can arise if the benefits of international risk sharing are to be fully exploited. On this note, we conclude with a word of caution against describing international market co-movements as contagions.
