Abstract

Has the euro improved trade evenly across member states? This paper revisits the impact of the euro on trade, focusing on systematic heterogeneity between core and peripheral members. I develop a stylized conceptual framework showing that while the elimination of exchange-rate volatility should raise trade for all European Monetary Union (EMU) members, other forms of price convergence may generate asymmetric effects. Using bilateral trade data from 1960–2018, I estimate a gravity model with Poisson pseudo maximum likelihood (PPML) and apply a doubly robust inverse-propensity score weighting estimator. The results show that the average EMU effect masks substantial heterogeneity across member states. On average, euro membership increases trade by about 6%, with stronger gains, around 12%-for core country exports (to both core and periphery destinations) and within periphery exports. However, trade flows from the periphery to core members decline by an estimated 7%.
