This paper shows how variation in the intertemporal marginal rate of substitution can account for several puzzling features of cyclical fluctuations in international trade volumes. Our insight is that because international trade is time-intensive, variation in the rate at which agents are...

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 argue that the welfare gains from trade in new models with micro-level margins exceed those in frameworks without these margins. Theoretically, we show that for fixed trade elasticity, different models predict identical trade flows, but different patterns of micro-level price variation. Thus,...
