I examine the implications of employer learning and statistical discrimination for initial employment rates, wages, and occupational attainment and for wage growth and occupational change over a career using a model in which the sensitivity of productivity to worker skill is increasing in the...

This paper uses a college-by-graduate degree fixed effects estimator to evaluate the returns to 19 different graduate degrees for men and women. We find substantial variation across degrees, and evidence that OLS over-estimates the returns to degrees with the highest average earnings and...

We build an equilibrium model of a small open economy with labor market frictions and imperfectly enforced regulations. Heterogeneous firms sort into the formal or informal sector. We estimate the model using data from Brazil, and use counterfactual simulations to understand how trade affects...

This paper develops the nonparametric identification of models with production complementarities, worker-firm specific disutility of labor and search frictions. Mobility in the model is subject to preference shocks, and we assume that firms can write wage contracts. We develop a constructive...
