【摘要】We evaluate the bias from endogenous job mobility in fixed-effects estimates of worker- andfirm-specific earnings heterogeneity using longitudinally linked employer-employee data from theLEHD infrastructure file system of the U.S. Census Bureau. First, we propose two new residualdiagnostic tests of the assumption that mobility is exogenous to unmodeled determinants ofearnings. Both tests reject exogenous mobility. We relax the exogenous mobility assumptions bymodeling the evolution of the matched data as an evolving bipartite graph using a Bayesian latentclass framework. Our results suggest that endogenous mobility biases estimated firm effects towardzero. To assess validity, we match our estimates of the wage components to out-of-sampleestimates of revenue per worker. The corrected estimates attribute much more of the variation inrevenue per worker to variation in match quality and worker quality than the uncorrected estimates.
