Are international borders barriers to capital flows? We use evidence on net capital flows among regions within a country as a benchmark. For this purpose we develop a data set of saving and investment rates of Japanese prefectures. We find that the correlation between saving and investment rates...

Obstfeld and Rogoff (2000) have reinvigorated an old literature on the link between home bias in the goods markets and home bias in the asset market by arguing that trade costs in the goods market can account for the observed portfolio home bias. The key link between home bias in the two markets...

We propose a new methodology to evaluate the gains from global risksharing that is closely connected to the empirical growth literature. We obtain estimates of residual risk (growth uncertainty) at various horizons from regressions of country-specific deviations from world growth on a wide set...

We decompose aggregate saving and investment into its public and private components and then document a variety of "stylized facts" associated with saving and investment rates of a sample of 15 countries over the period 1975-1989. In order to see whether these empirical relationships are...

We develop a theory to account for changes in net capital flows of safe and risky assets over the global financial cycle. We show empirically that countries that have a net debt of safe assets experience a rise in net outflows of safe assets (reduced accumulation of safe debt) during a downturn...

We develop a theory to account for changes in gross and net capital flows over the global financial cycle (GFC). The theory relies critically on portfolio heterogeneity among investors within and across countries, related to risky portfolio shares and portfolio shares allocated to foreign...

We develop a new theory of international capital flows based on dispersed information across individual investors. There is extensive evidence of information heterogeneity within and across countries, which has proven critical to understanding asset price behavior. We introduce information...

The past decade has witnessed an explosion of papers estimating gravity equations for cross-border financial holdings. The aim of the paper is to develop a theoretical foundation for the empirical gravity literature applied to finance. The gravity specification is closely analogous to that...
