This paper examines alternative forms of match bias arising from earnings imputation. Wage equation parameters are estimated based on mixed samples of workers who do and do not report earnings, the latter group being assigned earnings of donors who share some but not all the attributes of the...

This article examines match bias arising from earnings imputation. Wage equation parameters are estimated from mixed samples of workers reporting and not reporting earnings, the latter assigned earnings of donors. Regressions including attributes not used as imputation match criteria (e.g.,...

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...

A key concern in estimating the effect of military service on civilian earnings is bias from unmeasured differences between military veterans and nonveterans. The effects of activeduty service are estimated using the 1986 and 1992 Reserve Components Surveys, which permit a matched comparison...

This paper examines covariates of the occupational age structure and the openness of jobs to older workers. Using a large number of data sets, which together span the years 1983-98, the authors focus on the structure of compensation, job skill requirements, and working hours and conditions as...

Part-time workers receive considerably lower wages than do full-time workers. Using Current Population Survey earnings files for September 1995 through December 2002, the author finds that measurable worker and job characteristics, including occupational skill requirements, account for much of...

Microdata are used to examine the relative ability of the human capital model and of an alternative national distribution hypothesis to generate predicted distributions of earnings that are close to actual distributions within 48 SMSAs. Surprisingly, the national distribution hypothesis is found...

Hirsch develops a model of union rent-seeking in which the unions capture a share of quasi-rents that make up the normal ROI in long-lived capital and R&D. He finds that in response, firms adjust their investments in vulnerable tangible and intangible capital. Hirsch also attempts to explain the...

The effect of active-duty service on civilian earnings is estimated using the Reserve Components Surveys, permitting a matched comparison between reservists who are veterans and reservists without active-duty service. Estimated treatment effects control for selection by the military and...
