A central puzzle in international finance is that real exchange rates are volatile and, in stark contradiction to efficient risk-sharing, negatively correlated with relative consumptions across countries. This paper shows that a model with incomplete markets and a low price elasticity of imports...

Since the adoption of flexible exchange rates in the early 1970s, real exchange rates have been much more volatile than they were under Bretton Woods. However, the literature showed that the volatilities of most other macroeconomic variables have not been affected by the change in exchange-rate...

A central puzzle in international finance is that real exchange rates are volatile and, in stark contradiction to effcient risk-sharing, negatively correlated with cross-country consumption ratios. This paper shows that incomplete asset markets and a low price elasticity of tradables can account...

This chapter studies optimal monetary stabilization policy in interdependent open economies, by proposing a unified analytical framework systematizing the existing literature. In the model, the combination of complete exchange-rate pass-through ('producer currency pricing') and frictionless...

Since the adoption of flexible exchange rates, real exchange rates have been much more volatile than they were under Bretton Woods. However, the volatilities of most other macroeconomic variables have remained approximately unchanged. This poses a puzzle for standard international business cycle...

This paper analyzes the cross-country effects of productivity and demand disturbances in the United States identified with sign restrictions based on standard theory. Productivity gains in US manufacturing increase US consumption and investment vis-à-vis foreign countries, resulting in a trade...

Should monetary policy be preoccupied with large current account imbalances and extremely volatile exchange rates? Using a standard open economy model of pricing-to-market with incomplete asset markets and nominal rigidities, we show that the answer is yes. In our framework, supply shocks...
