Recent theoretical work on international trade emphasizes the importance of trade elasticity as the fundamental statistic needed to conduct welfare analysis. Eaton and Kortum (2002) proposed a two-step method to estimate this parameter, where exporter fixed effects are regressed on proxies for...

Ricardian theories of production often take the comparative advantage of locations in different industries to be uncorrelated. They are seen as the outcome of the realization of a random extreme value distribution. These theories do not take a stance regarding the counterfactual or implied...

W ostatnich latach coraz śmielej formułuje się hipotezę głoszącą, że światowym handlem na powrót rządzi klasycznie interpretowana przewaga komparatywna, co umniejsza znaczenie osiągnięć nowych ujęć teoretycznych i zarazem przywraca aktualność tradycyjnej teorii handlu...

Este trabajo presenta dos modelos de equilibrio parcial que permiten analizar los ajustes estratégicos de precio por parte de los exportadores colombianos, frente a variaciones en la tasa de cambio (Pricing to market). El documento confirma resultados previos, en el sentido de que para el...

Quantitative results from a large class of structural gravity models of international trade depend critically on the elasticity of trade with respect to trade frictions. We develop a new simulated method of moments estimator to estimate this elasticity from disaggregate price and trade-flow data...
