Disaggregated trade and disaggregated currency unions: a ranking of common currency effects
Working papers (2015)

Andrew Rose has long argued that a common currency has a large effect on increasing trade.  Recently, Rose has called into question the reliability of this conclusion, as new techniques have emerged for estimating gravity equations.  This paper uses the sector-specific gravity model developed by Anderson & Yotov (2010) to investigate if disaggregated trade can provide a reliable estimate of a common currency's effect.  Disaggregating trade alone is insufficient to obtain a reliable estimate of a currency union, regardless of econometric technique, when the effect of a common currency on trade is uniform across all unions.  Disaggregating the universe of currency unions with individual effects provides a reliable ranking of currency unions, independent of estimation method, by the effect that each union's currency has on increasing trade.  These rankings differ across sectors.
