Abstract

Little is known about the consequence of firm heterogeneity and its resulting reallocation effect on international consumption risk sharing. This paper explores international risk sharing in a theoretical model with firm heterogeneity and shows that firm heterogeneity changes the nature of international risk sharing, thus driving a wedge between relative consumption growth and real exchange rate fluctuations. A correlation is found to be conditional on the fluctuations in the number of product varieties and their qualities arising from the reallocation effect induced by heterogeneous firms; the conventional unconditional correlation can be thus biased. Using world trade data covering more than two decades, I note the existence of bias and find that the extent of international risk sharing is underestimated. The analysis indicates a larger welfare gain from international trade than we have been measuring.
