We show in the context of a new economic geography model that when labor is heterogenous trade liberalization may lead to industrial agglomeration and interregional trade. Labor heterogeneity gives local monopoly power to firms but also introduces variations in the quality of the job match....

We analyze labor market models where the law of one price does not hold-that is, models with equilibrium wage dispersion. We begin by assuming workers are ex ante heterogeneous, and highlight a flaw with this approach: if search is costly, the market shuts down. We then assume workers are...

Search models with posting and match-specific heterogeneity generate wage dispersion. Given K values for the match-specific variable, it is known that there are K reservation wages that could be posted, but generically never more than two actually are posted in equilibrium. What is unknown is...

Using Chilean data, we document that for resource-rich small open economies the effects of terms of trade shocks on the wage gap (between skilled and unskilled workers) depend on factor intensities in the non-tradable sector, following the model in Galiani, Heymann, and Magud (2010). For a...
