- Abstract
- How should monetary policy respond to excessive capital in•ows that appreciate the currency and widen the external de•cit? Using the workhorse two-country open-macro model, we derive a quadratic approximation of the utility-based global loss function in incomplete market economies, and solve for the optimal targeting rules under cooperation. The optimal monetary stance is expansionary if the exchange rate pass-through (ERPT) on import prices is complete, contractionary if nominal rigidities attenuate ERPT. Excessive capital in•ows, however, may lead to currency undervaluation instead of overvaluation for some parameter values. The optimal stance is then invariably expansionary to support domestic demand.

- Abstract
- 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 quantitatively for these properties of real exchange rates. The low price elasticity stems from distribution services, intensive in local inputs, which drive a wedge between producer and consumer prices and lower the impact of terms-of-trade changes on optimal agents' decisions. Two very different patterns of the international transmission of productivity improvements generate the observed degree of risk-sharing: one associated with a strengthening, the other with a deterioration of the terms of trade and real exchange rate. Evidence on the effect of technology shocks to U.S. manufacturing, identified through long-run restrictions, is found in support of the first transmission pattern, questioning the presumption that terms-of-trade movements foster international risk-pooling.
