trade barriers for manufacturing industries in European Union countries between 1999 and 2003. We find a large degree of … trade cost heterogeneity across industries. The most important trade barriers are transportation costs and policy factors …

This paper derives a micro-founded gravity equation based on a translog demand system that allows for flexible … substitution patterns across goods. In contrast to the standard CES-based gravity equation, translog gravity generates an … trade flows predicted to be zero. I test the translog gravity equation and find empirical evidence that is in many ways …

used as regressors in a gravity equation of trade. Instead, the indirect approach infers the extent of trade impediments …

using one particular illustration, the gravity equation for trade, and apply the proposed technique to provide new estimates … obtained with the traditional method. These discrepancies persist even when the gravity equation takes into account …

class of trade models that satisfy a "gravity equation," the welfare gains from trade can be computed using only the open …
