High interest rates to defend the exchange rate signal that a government is committed to fixed exchange rates, but may also signal weak fundamentals. We test the effectiveness of the interest rate defense by disaggregating into the effects on future interest rates differentials, expectations of...

Obstfeld and Rogoff (2000) have reinvigorated an old literature on the link between home bias in the goods market 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...

On the eve of a major change in the world monetary system, the adoption of a single currency in Europe, our theoretical understanding of the implications of the exchange rate regime for trade and capital flows is still limited. We argue that two key model ingredients are essential to address...

In theory, we should expect tariffs to be partially offset by a currency appreciation in the tariff-imposing country or by a depreciation in the country on which the tariff is imposed. We find, based on a calibrated model, that the tariffs imposed by the US in 2018-19 should not have had a large...

This paper provides an empirical examination of the hypothesis that the forward exchange rate provides an quot;optimalquot; forecast of the future spot ex-change rate, for five currencies relative to the dollar. This hypothesis provides a convenient norm for examining the erratic behavior of...

Existing empirical evidence suggests that real exchange rates exhibit hump-shaped dynamics. I show that this is a robust fact across nine large, developed economies. This fact can help explain why existing sticky-price business cycle models have been unable to match the persistence of the real...

We show that quot;commodity currencyquot; exchange rates have remarkably robust power in predicting global commodity prices, both in-sample and out-of-sample, and against a variety of alternative benchmarks. This result is of particular interest to policymakers, given the lack of deep forward...

Most analyses of the macroeconomic adjustment required to correct global imbalances ignore net exports of new varieties of goods and services and do not account for firms' entry in the product market. In this paper we revisit the macroeconomics of trade adjustment in the context of the classic...

We analyze the policy trade-offs generated by local currency price stability of imports in economies where upstream producers strategically interact with downstream firms selling the final goods to consumers. We study the effects of staggered price setting at the downstream level on the optimal...
