In our two-stage approach, estimates at the first stage suggest that belonging to a currency union/board triples trade with other currency union members.  Moreover, there is no evidence of trade diversion.  Our estimates at the second stage suggest that every 1 percent increase in a country's overall trade (relative to GDP) raises income per capita by at least one-third of a percent.  We combine the two estimates to quantify the effect of common currencies on output.  Our results support the hypothesis that important beneficial effects of currency unions come through the promotion of trade. - Reproduced.  aIncome  aTrade  aCurrencies  aRose, Andrew  aQuarterly Journal of Economics
