The Euro and the Geography of International Debt Flows
Greater financial integration between core and peripheral EMU members had an effect on both sets of countries. Lower interest rates allowed peripheral countries to run bigger deficits, which inflated their economies by allowing credit booms. Core EMU countries took on extra foreign leverage to expose themselves to the peripherals. The result has been asset-price bubbles and collapses in some of the peripheral countries, area-wide banking crisis, and sovereign debt problems. We analyze the geography of international debt flows using multiple data sources and provide evidence that after the ...

Falling Oil Prices and Global Saving
The rise in oil prices from near $30 per barrel in 2000 to around $110 per barrel in mid-2014 was a dramatic reallocation of global income to oil producers. So what did oil producers do with this bounty? Trade data show that they spent about half of the increase in total export revenues on imports and the other half to buy foreign assets. The drop in oil prices will unwind this process. Oil-importing countries will gain from lower oil bills, but they will also see a decline in their exports to oil-producing countries and in purchases of their assets by investors in these countries. Indeed, ...

The Hedging Channel of Exchange Rate Determination
We document the exchange rate hedging channel that connects country-level measures of net external financial imbalances with exchange rates. In times of market distress, countries with large positive external imbalances (e.g. Japan) experience domestic currency appreciation, and crucially, forward exchange rates appreciate relatively more than the spot after adjusting for interest rate differentials. Countries with large negative foreign asset positions experience the opposite currency movements. We present a model demonstrating that exchange rate hedging coupled with intermediary constraints ...

Asset Bubbles and Global Imbalances
We analyze the relationships between bubbles, capital flows, and economic activities in a rational bubble model with two large open economies. We establish a reinforcing relationship between global imbalances and bubbles. Capital flows from South to North facilitate the emergence and the size of bubbles in the North. Bubbles in the North in turn facilitate South-to-North capital flows. The model can simultaneously explain several stylized features of recent bubble episodes.

Uninsurable Income Risk and the Welfare Effects of Reducing Global Imbalances
We highlight the welfare effect of policies that balance global current accounts when households face uninsurable income risk and borrowing constraints. Subsidizing savings in debtor economies reduces current account imbalances and raises the welfare of almost all citizens by increasing world capital, raising wages, and improving insurance for low-wealth households. The same balancing of current accounts is achieved by taxing savings in lender economies; however, this policy hurts most households by reducing global capital. These results suggest that balancing global imbalances may be a ...
