This paper provides evidence on the consumption effects of trade shocks by exploiting changes in US and Chinese trade policy between 2017 and 2018. The analysis uses a unique data set with the universe of new auto sales at the US county level, at a monthly frequency, and a simple...

This paper shows how the dynamics of the firm yield new insights into the short- and long-run economic outcomes from changes in immigration policy. I quantitatively illustrate these insights by evaluating two policies: an expansion of and the elimination of the H-1B visa program for skilled...

This paper studies the implications of household heterogeneity for trade. I develop a model where household heterogeneity is induced via incomplete markets and results in heterogeneous price elasticities. Conditional on exposure to trade, heterogeneous price elasticities imply that different...

This paper studies household inequality and product market power in dynamic, general equilibrium. In our model, households' price elasticities of demand endogenously vary with wealth. Heterogeneous firms set their price as oligopolistic competitors given the endogenous distribution of demand. A...

Recent studies find that observational returns to rural-urban migration are near zero in three developing countries. We revisit this result using panel tracking surveys from six countries, finding higher returns on average. We then interpret these returns in a multi-region Roy model with...

In this paper we derive a new measure of openness--trade potential index--that quantifies potential gains from trade as a simple function of data. Using a standard multicountry trade model, we measure openness by a country's potential welfare gain from moving to a world with frictionless trade....

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...
