GeoDist makes available the exhaustive set of gravity variables used in Mayer and Zignago (2005). GeoDist provides several geographical variables, in particular bilateral distances measured using citylevel data to assess the geographic distribution of population inside each nation. We have...

Firm-level regressions show that Champagne producers that receive better ratings from wine guides also export to more markets, charge higher prices, and sell more in each market. Our method corrects for a severe selection bias predicted by the model. By using direct measures of quality, we can...

This paper documents the construction of BACI, our international trade database, which covers more than 200 countries and 5,000 products, between 1994 and 2007. New approaches have been developed to reconcile data reported by almost 150 countries to the United Nations Statistics Division,...

Recent findings in international trade using detailed firm level surveys emphasize the microeconomic effects of trade liberalization episodes. A unilateral trade reform has two opposite effects on firms’ export patterns: (i) expansion of export opportunities for foreign firms exporting to that...

Recent trade models with heterogenous firms have considerable consequences on the interpretation of gravity equations. Chaney (2008) shows that the effect of distance on trade margins incorporates three parameters: the elasticity of substitution between goods, the elasticity of trade costs with...

Competitiveness has come to the forefront of the policy debate within the European Union, focusing on price competitiveness and intra-EU imbalances. But how to measure competitiveness properly, beyond price or cost competitiveness, remains an open methodological issue; and how can we explain the...

This paper studies the implications of Preferential Trade Agreements (PTAs) proliferation. Using counterfactual estimation, we disentangle the treatment effect of one PTA on members’ trade and real income, from the externalities created by concurrent trade policy changes. Results, focusing on...

Influential empirical work by Rauch and Trindade (REStat, 2002) finds that Chinese ethnic networks of the magnitude observed in Southeast Asia increase bilateral trade by at least 60%. We argue that this estimate is upward biased due to omitted variable bias. Moreover, it is partly related to a...
