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 …

endogeneity and attrition/non-response bias, using two instrumental variables. Making use of a discrete instrument for the …

test two main hypotheses: (i) whether for items not perfectly observable, individuals suffer of some type of bias in these … beliefs; (ii) whether this bias would disappear for weight and height, when the information is perfectly available. We find a … powerful and ubiquitous bias in perceptions that is "self-centered" in the sense that those at extremes tend to perceive …

This paper documents that rotation group bias – the tendency for labor force statistics to vary systematically by month … groups; both should be nationally representative samples. The rise in rotation group bias is driven by a growing tendency for … bias.We find that rotation group bias increased discretely after the 1994 CPS redesign and that rising nonresponse is …

This paper uses the control function to develop a framework for testing for selection bias. The idea behind our … magnitude of potential selection bias. Averaging this correction term with respect to appropriate weights yields the degree of … selection bias for alternative treatment effects of interest. One advantage of our framework is that it motivates when is …
