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...

We show that the negative impact of financial crises on trade is magnified for destinations with longer time-to-ship. A simple model where exporters react to an increase in the probability of default of importers by increasing their export price and decreasing their export volumes to...

With increasing sophistication, economists have been estimating gravity equations for five decades. Robust evidence shows that borders and distance impede trade by much more than tariffs or transport costs can explain. We therefore advocate investigation of other sources of resistance, despite...

This chapter focuses on the estimation and interpretation of gravity equations for bilateral trade. This necessarily involves a careful consideration of the theoretical underpinnings since it has become clear that naive approaches to estimation lead to biased and frequently misinterpreted...

Based on matching techniques in combination with a difference-in-difference estimator, this paper estimates the effects at home of initiating production abroad through the establishment of a foreign production affiliate. The analysis covers manufacturing and service firms active in France during...

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...
