Title: Currency Unions in Prospect and Retrospect

Author(s): J.M.C Santos Silva and Silvana Tenreyro

Publication Date: May 2010

Keyword(s): currency union and euro

Programme Area(s): International Macroeconomics

Abstract: We critically review the recent literature on currency unions, and discuss the methodological challenges posed by the empirical assessment of their costs and benefits. In the process, we provide evidence on the economic effects of the euro. In particular, and in contrast with estimates of the trade effect of other currency unions, we find that the impact of the euro on trade has been close to zero. After reviewing the costs and benefits, we conclude with some open questions on normative and positive aspects of the theory of currency unions, emphasizing the need for a unified welfare-based framework to weigh their costs and gains.
