This paper presents new descriptive evidence regarding marital pay premiums earned by white males. Longitudinal data indicate that wages rise after marriage, and that cross-sectional marriage premiums appear to result from a steepening of the earnings profile. Data from a company personnel file...

We explore several problems in drawing causal inferences from cross-sectional relationships between marriage, motherhood, and wages. We find that heterogeneity leads to biased estimates of the "direct" effects of marriage and motherhood on wages (i.e., effects net of experience and tenure);...

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 the two sources of bias are...

We investigate income, marital status, and hourly pay differentials by body mass (kg/m ²) in a sample of 23- to 31-year-olds drawn from the 1988 NLSY. Obese women have lower family incomes than women whose weight-for-height is in the "recommended" range. Results for men are weaker and mixed. We...

This paper analyzes the effects of illicit drug use on the labor supply of a sample of young adults using data from the National Longitudinal Survey of Youth. The paper investigates whether the frequency and timing of marijuana and cocaine use are systematically related to labor supply, and...

We investigated whether the September 11, 2001 terrorists’ attacks had any effect on employment, earnings, and residential mobility of first- and second-generation Arab and Muslim men in the United States. We find that September 11th did not significantly affect employment and hours of work of...
