Trade and Welfare Under Alternative Exchange Rate Regimes

WP #04008, February 2004

This paper compares the welfare under two standard alternative exchange rate regimes, fixed and flexible, in a stochastic dynamic general equilibrium two-country setting. Conventional wisdom holds that countries often prefer low exchange-rate variability to stabilize trade. This may explain the observed `fear of floating' in emerging markets -- although most of them claim to adopt a flexible system, in reality they often intervene to peg. We show that under incomplete capital markets a fixed exchange rate regime unambiguously increases trade and improves welfare. This provides a potential explanation for the observed exchange rate policies in emerging markets.
