Measurement errors in survey data on hourly pay may lead to serious upward bias in low pay estimates. We consider how to correct for this bias when auxiliary accurately measured data are available for a subsample. An application to the UK Labour Force Survey is described. The use of fractional...

I examine evidence on private sector union wage gaps in the U.S. The consensus opinion among labor economists of an average union premium of roughly 15 percent is called into question. Two forms of measurement error create a downward bias in standard wage gap estimates. Match bias results from...

About 30% of workers in the CPS have earnings imputed. Wage gap estimates are biased toward zero when the attribute being studied (e.g., union status) is not a criterion used to match donors to nonrespondents. An expression for ?match bias? is derived in which attenuation equals the sum of match...

This paper investigates the effect of parents’ current income and long-term family characteristics on individuals’ highest educational qualification obtained by age 26 using UK data from the 1970 British Cohort Study. The issues of the possible sample selection bias produced by the not...
