Financial Integration and Growth in a Risky World

A new Journal of Monetary Economics article from Nicolas Coeurdacier, Helene Rey, and Pablo Winant on how financial integration can transform the capital flows between two countries:

We revisit the debate on the benefits of financial integration in a two-country neoclassical growth model with aggregate uncertainty. The framework accounts simultaneously for gains from a more efficient capital allocation and gains from risk sharing—together with their interaction. Global numerical methods allow for meaningful welfare comparisons. Gains from integration are quantitatively small, even for riskier and capital scarce emerging economies. These countries import capital for efficiency reasons before exporting it for self-insurance, leading to capital flows and growth reversals along the transition. This opens the door to richer empirical implications than previously considered in the literature.
