We study a simple, tractable model of labor adjustment in a trade model that allows us to analyze the economy's dynamic response to trade liberalization. Since it is a neoclassical market-clearing model, we can use duality techniques to study the equilibrium, and despite its simplicity a rich...

The welfare effects of trade shocks depend crucially on the nature and magnitude of the costs workers face in moving between sectors. The existing trade literature does not directly address this, assuming perfect mobility or complete immobility, or adopting reduced-form approaches to estimation....

We construct a dynamic, stochastic rational expectations model of labor reallocation within a trade model that is designed so that its key parameters can be estimated for trade policy analysis. A key feature is the presence of time-varying idiosyncratic moving costs faced by workers. As a...

Under the TRIPS agreement, WTO members are required to enforce product patents for pharmaceuticals. The debate about the merits of this requirement has been extremely contentious. Many low income economies claim that patent protection for pharmaceuticals will result in substantially higher...
