This paper provides an expression for the bias of the OLS estimator of the schooling coefficient in a simple static … coefficient is biased upward, and the bias is increasing with potential labor-market experience and the degree of earnings … persistence. In addition, NLSY data are used to show that the magnitude of the persistence bias is non-negligible, and the bias …

) bias in β^. We add to this literature in two important ways. First, we focus on estimation of the fixed effects proper, as … these have become increasingly important in applied work.Second, we build on a bias-reduction approach originally developed …

We assess selection bias in estimated returns to workplace training by exploiting a field experiment with random …. When controlling for pre-treatment performance or individual fixed effects, only about one tenth of this bias remains and …

This paper introduces bias-corrected estimators for nonlinear panel data models with both time invariant and time …/selection bias. We then estimate the primary equation by fixed effects including an appropriately constructed control function from … both steps might employ nonlinear fixed effects procedures it is necessary to bias adjust the estimates due to the …

We characterize the bias of propensity score based estimators of common average treatment effect parameters in the case …

This paper develops a novel wild bootstrap procedure to construct robust bias-corrected (RBC) valid confidence …
