|August 2018||Global Value Chains and Inequality with Endogenous Labor Supply|
with Eunhee Lee: w24884
We assess the role of global value chains in transmitting global integration shocks to aggregate trade, as well as distributional outcomes. We develop a multi-country general equilibrium trade model that features multi-stage production, with different stages having different productivities and using factors (occupations) with different intensities. The model also features a Roy mechanism, in which heterogeneous workers endogenously choose their sector and occupation. Country- and worker-level comparative advantages interact. A reduction in trade costs leads to countries specializing in their comparative advantage sectors and production stages. This specialization changes labor demand, and also leads to more workers shifting to their comparative advantage sectors and occupations. We calibra...

|December 2012||The Great Trade Collapse|
with Rudolfs Bems, Robert C. Johnson: w18632
We survey recent literature on the causes of the collapse in international trade during the 2008-2009 global recession. We argue that the evidence points to the collapse in aggregate expenditure, concentrated on trade-intensive durable goods, as the main driver of the trade collapse. Inventory adjustment likely amplified the impact of these expenditure changes on trade. In addition, shocks to credit supply constrained export supply further exacerbating the decline in trade. Most evidence suggests that changes in trade policy did not play a large role. We conclude that one benefit of the trade collapse is that it has stimulated research in neglected areas at the intersection of trade and macroeconomics.
