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 1901, six Australian states joined together in political and economic union, creating an internal free trade area and adopting a common external tariff. This paper investigates the impact of federation on Australia's internal and international trade flows by studying changes in the "border...

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...

In the two years after the imposition of the Smoot-Hawley tariff in June 1930, the volume of U.S. imports fell over 40 percent. To what extent can this collapse of trade be attributed to the tariff itself versus other factors such as declining income or foreign retaliation? Partial and general...

Should a nation's tax system become more progressive as it opens to trade? Does opening to trade change the benefits of a progressive tax system? We answer these question within a standard incomplete markets model with frictional labor markets and Ricardian trade. Consistent with empirical...

We study how opening to trade affects economic growth in a model where heterogeneous firms can choose to adopt a new technology already in use by other firms. We characterize the growth rate using summary statistics of the profit distribution--the ratio of profits between the average and...

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...

On August 15, 1971, President Richard Nixon closed the gold window and imposed a 10 percent surcharge on all dutiable imports in an effort to force other countries to revalue their currencies against the dollar. The import surcharge was lifted four months later after the Smithsonian agreement...
