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...

In light of the substantial movement towards trade liberalization during the postwar period, this paper attempts to determine if, and when, countries experienced statistically significant changes in the paths of their export-GDP and import-GDP ratios. We find that: (1) most trade ratios...

This paper studies the dynamics of international trade flows at business cycle frequencies. We show that introducing dynamic considerations into an otherwise standard model of trade can account for several puzzling features of trade flows at business cycle frequencies. Our insight is that...

We analyze the impact of China's growth on the exports of other Asian countries. Our innovation is to distinguish the increase in China's demand for imports from its increased penetration of export markets. Using the gravity model, we disaggregate among commodity types and account for the...
