Everything You Always Wanted to Know About EU Membership Trade Effects But Were Afraid to Ask under submission
with Harald Oberhofer
This paper studies the role of data choices for trade policy estimates in structural gravity models. Drawing on 14 data sources and implementing alternative dataset restrictions, we obtain 643 unique estimates for the EU membership trade effect from a standard specification of the structural gravity model. These estimates are used as our dependent variable in a meta-regression analysis, which explores the heterogeneity of the estimated trade. The results highlight the crucial role of including domestic trade flows, which raise the EU membership trade effect estimate by more than 20 percentage points. The effect size estimates also vary with time- and country coverage, across time interval and annual panel data, alternative product classifications, the level of sectoral disaggregation and the use of imports as alternative outcome variable. The paper further studies the underlying reasons for the variation in the size of EU membership trade estimates and concludes with some practical recommendations.
