Abstract

We show in a tractable, multi-country OLG model that cross-country differences in financial development explain three recent empirical patterns of international capital flows. International capital mobility affects output in each country directly through the size of domestic investment as well as indirectly through the composition of domestic investment and the level of domestic savings. In contrast to earlier literature, our model admits the possibility that the indirect effects dominate the direct effects and international capital mobility raises output in the poor country and globally, although net capital flows are in the direction of the rich country. Our model adds to the understanding of the benefits of international capital mobility in the presence of financial frictions.
