A narrowing of the U.S. current account deficit through exchange rate movements is likely to entail a substantial depreciation of the dollar, as stressed in research by Obstfeld and Rogoff. We assess how the adjustment is affected by the high degree of financial integration in the world economy....

Current account crises in emerging markets are characterized by large increases in interest rates, big drops in output, and large real currency depreciations. Current models of crisis with financial frictions do not generate very large movements in these variables. Recent work has shown that the...

In spite of the concerns about “twin deficits†(fiscal and current account deficits) for the U.S., empirical evidence suggests that “twin divergence†is a more regular feature of the data: when the fiscal accounts worsen, the current account improves and vice versa. We thus...

Currency crises are usually associated with large real depreciations. In some countries real depreciations are perceived to be very costly("fear of floating"). In this paper we try to understand the reasons behind this fear. We first look at episodes of currency crises in the '90s and establish...

An unresolved issue in international macroeconomics is the apparent lack of risk-sharing across countries, which contradicts the prediction of models based on the assumption of complete markets. We asses the importance of international financial frictions in this issue by constructing an...

This paper presents a fully rational general equilibrium model that produces a time-varying exchange rate risk premium and solves the uncovered interest rate parity (U.I.P) puzzle. In this two-country model, agents are characterized by slow-moving external habit preferences similar to Campbell &...

In this paper, I argue that demographic factors play a central role in accounting for the trade deficit experienced by the U.S. during the last three decades. The main idea is that cross-country demographic differentials lead to adjustments in savings and investments which are associated with...

We argue that emerging economies borrow short term due to the high risk premium charged by bondholders on long-term debt. First, we present a model where the debt maturity structure is the outcome of a risk sharing problem between the government and bondholders. By issuing long-term debt, the...
