Using data from the 1997 cohort of the National Longitudinal Survey of Youth (NLSY-97), we examine the effects of California's paid family leave program (CA-PFL) on mothers' and fathers' use of leave during the period surrounding child birth, and on the timing of mothers' return to work, the...

This paper examines whether nutritional disruptions experienced during the stage of fetal development impair an individual's labor market productivity later in life. We consider intrauterine exposure to the month of Ramadan as a natural experiment that might cause shocks to the inflow of...

This paper shows how a shorter fecundity horizon for females (a biological constraint) leads to age and educational disparities between husbands and wives. Empirical support is based on data from a natural experiment commencing before and ending after China's 1980 one-child law. The results...

This paper analyses the economic issues associated with human cloning and new reproductive technologies. We analyze the incentives for human cloning and its implications for the long run distribution of skills and income. We analyse models of human cloning for different motives, focusing on...

This paper explores secular changes in women’s pay relative to men’s pay. It shows how the human capital model predicts a smaller gender wage gap as male-female lifetime work expectations become more similar. The model explains why relative female wages rose almost unabated from 1890 to the...

Since 1986 the United States has made considerable efforts to curb illegal immigration. This has resulted in an increase in migration costs for undocumented immigrants. More stringent border enforcement either deters potential illegal immigrants from coming to the U.S., or moves the point of...

Using microdata from the 1960-2000 decennial censuses, this paper explores how large initial differences in immigrant earnings by country of origin change with duration in the United States. One analysis reveals that country of origin adds less to the explanation of earnings, among working-age...

We examine changes in inequality and instability of the combined earnings of married couples over the 1980-2009 period using two U.S. panel data sets: Social Security earnings data matched to Survey of Income and Program Participation panels (SIPP-SSA) and the Panel Study of Income Dynamics....

We investigate the effects of maternity leave coverage on women’s post-birth wages, job tenure, and labor market attachment. We pay particular attention to unobservable characteristics that are correlated with maternity leave coverage and that affect labor market outcomes. We use a control...
