This paper formalizes a classic idea that in second-best environments trade can induce welfare losses. In a framework that incorporates distortion wedges into a Melitz model, we analyze a channel in which trade can reduce allocative efficiency arising from the reallocation of resources. A key...

This paper incorporates firm-level distortions into a Melitz model and characterizes welfare under misallocation. We derive an analogue to the well-known ACR result in an economy with distortions. We highlight a channel through which trade can reduce welfare by exacerbating misallocation. A key...

Commodity trade and financial asset trade are both integral parts of globalization, yet little has been studied on their interplay. In a framework that integrates these two paradigms of trade, a new force driving international capital flows emerges: capital tends to flow towards countries that...

The `quantity anomalies' that arise from standard international business cycle models are cross-country correlations in consumption being higher than output, and negative comovement in aggregate investment and employment. This paper shows that incorporating multiple sectors with heterogeneous...

This paper provides a new theory of international capital ows. In a frameworkthat integrates factor-proportions-based trade and nancial capital ows, a novel forceemerges: capital tends to ow towards countries that become more specialized incapital-intensive industries. This `composition' eect...

We examine how U.S. monetary and fiscal policy shocks affect emerging markets’ aggregate economy. We find that emerging markets’ reaction to U.S. policy shocks differ widely from those of industrialized countries. Expansionary policies tend to depreciate the currencies of emerging...
