In this paper, I present a simple characterization of the sample selection bias problem that is also applicable to the … problem of sample selection bias is fit within the conventional specification error framework of Griliches and Theil. A simple … estimator is discussed that enables analysts to utilize ordinary regression methods to estimate models free of selection bias …

first characterize the biases in both network statistics and estimates of network effects under non-random sampling … theoretically and numerically. Sampled network data systematically bias the properties of observed networks and suffer from non …-classical measurement-error problems when applied as regressors. Apart from the sampling rate and the elicitation procedure, these biases …

empirical results reject the hypothesis that an increase in the upward bias of the schooling coefficient, due to a change in the …

Meta-regression estimates of the value of a statistical life (VSL) controlling for publication selection bias yield … bias-corrected estimates of VSL that are higher for labor market studies using the more recent Census of Fatal Occupational … of the variable used to capture publication bias effects. Meta-regression estimates for a large sample of VSL estimates …

We introduce a unified and …

This paper documents that rotation group bias -- the tendency for labor force statistics to vary systematically by … 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 …
