Title: Trade shocks and labor adjustment
Description: "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 consequence of these shocks: (i) Gross flows exceed net flows (an important feature of empirical labor movements); (ii) the economy features gradual and anticipatory adjustment to aggregate shocks; (iii) wage differentials across locations or industries can persist in the steady state; and (iv) the normative implications of policy can be very different from a model without idiosyncratic shocks, even when the aggregate behaviour of both models is similar.  It is shown that the equilibrium solves a particular planner's problem, thus facilitating analytical results, econometric estimation, and simulation of the model for policy analysis"--National Bureau of Economic Research web site.
