November 2012Trade Policy and Wage Inequality: A Structural Analysis with Occupational and Sectoral Mobility
with John McLaren: w18503
A number of authors have argued that a worker's occupation of employment is at least as important as the worker's industry of employment in determining whether the worker will be hurt or helped by international trade. We investigate the role of occupational mobility on the effects of trade shocks on wage inequality in a dynamic, structural econometric model of worker adjustment. Each worker in our specification can switch either industry, occupation, or both, paying a time-varying cost to do so in a rational-expectations optimizing environment. We find that the costs of switching industry and occupation are both high, and of similar magnitude, but in simulations we find that a worker's industry of employment is much more important than either the worker's occupation or skill class in dete...

October 2007Trade Shocks and Labor Adjustment: A Structural Empirical Approach
with Shubham Chaudhuri, John McLaren: w13465
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 present a model of dynamic labor adjustment that does, and which is, moreover, consistent with a key empirical fact: that intersectoral gross flows greatly exceed net flows. Using an Euler-type equilibrium condition, we estimate the mean and the variance of workers' switching costs from the U.S. March Current Population Surveys. We estimate high values of both parameters, implying both slow adjustment of the economy, and sharp movements in wages, in response to a trade shock. Simulations of a t...
