Firm Wage Differentials and Labor Market Sorting: Reconciling Theory and Evidence
Published in Journal of Political Economy
Abstract:
Why do firms pay different wages? Empirical evidence suggests the presence of substantial differences in firm pay controlling for worker skill. Moreover, these differences are uncorrelated with skills, indicating the absence of sorting. I show that the face value interpretation is inconsistent with evidence on coworker segregation. I interpret the evidence by applying a sorting model and show that the correlation is biased. I identify nonmonotonicities in wages as the reason for this bias and show that a measure of worker-coworker sorting is more accurate. By calibrating the model to US data, I confirm that the model matches many job market characteristics.
