Abstract

We develop and test a theory of efficient international trade. Efficiency gains arise through lower trade costs faced by 'trade specialists', whose superiority over 'common traders' manifests itself through lower trade costs. To test our theory, we construct and deploy a novel dataset based on firm-level merchanting data. Our estimates reveal that, on average, the trade costs for the 'trade specialists' are about four times lower than for non-specialists. The corresponding welfare effects from globally efficient trade amount to a remarkable gain of 80%, on average, which sends an encouraging message for the potential gains from trade that are missing in the existing literature.
