We present evidence on changes in workplace segregation by education, race, ethnicity, and sex, from 1990 to 2000. The evidence indicates that racial and ethnic segregation at the workplace level remained quite pervasive in 2000. At the same time, there was fairly substantial segregation by...

We examine evidence on omitted-ability bias in estimates of the economic return to schooling, using proxies for unobserved ability. We consider measurement error in these ability proxies and the potential endogeneity of both experience and schooling, and examine wages at labor market entry and...

This paper evaluates the effects of the earned income tax credit (EITC) on poor families. Exploiting state-level variation in EITCs, we find that the EITC helps families rise above poverty-level earnings. This occurs by inducing labor market entry in families that initially do not have an adult...

In earlier work we examined the temporal evolution of job stability in U.S. labor markets through the 1980's, using data assembled from a sequence of Current Population Survey tenure supplements. We found little or no change in aggregate job stability in the U.S. economy. In addition, older and...

We attempt to draw inferences about potential behavioral responses to means-tested" income support for the elderly by examining the effects on saving of the Supplemental Security" Income (SSI) program for the aged in the U.S. Part of the SSI program provides payments to the" poor elderly, thus...

We present a new approach to estimating minimum wage effects on employment. In contrast to most previous research, we account for the possibility that the relationship between minimum wages and employment depends on the magnitude of the minimum wage relative to the equilibrium wage in the...

We examine the possible sources of the larger racial and ethnic wage gaps for men than for women in the U.S. Specifically, using a newly created employer-employee matched data set containing workers in essentially all occupations, industries, and regions, we examine whether these wage...

We use data on sisters to jointly address heterogeneity bias and endogeneity bias in estimates of wage equations for women. This analysis yields evidence of biases in OLS estimates of wage equations for white and black women, some of which are detected only when these two sources of bias are...

This paper reviews evidence on age discrimination in U.S. labor markets and on the effects of the Age Discrimination in Employment Act (ADEA) in combating this discrimination. It focuses on the challenge of population aging facing the U.S. economy in coming decades. Combating age discrimination...

The elderly are one of the exceptional groups in American society with access to a significant cash safety net, a means-tested program called Supplemental Security Income (SSI). Little attention has been paid to the pre-eligibility-age labor market disincentives created by such a program. In...
