A growing literature seeks to explain why so many more women than men now attend college. A commonly cited stylized fact is that the college wage premium is, and has been, higher for women than for men. After identifying and correcting a bias in estimates of college wage premiums, I find that there has been essentially no gender difference in the…

We estimate the trend in the transitory variance of male earnings in the United States using the Michigan Panel Study of Income Dynamics from 1970 to 2004. Using an error components model and simpler but only approximate methods, we find that the transitory variance started to increase in the early 1970s, continued to increase through the…

Using Spanish Social Security records, we document the channels through which mothers fall onto a lower earnings track, such as shifting into part- time work, accumulating lower experience, or transitioning to lower-paying jobs, and are able to explain 71 percent of the unconditional individual fixed- effects motherhood wage gap. The earnings…

Speech patterns differ substantially between whites and many African Americans. I collect and analyze speech data to understand the role that speech may play in explaining racial wage differences. Among blacks, speech patterns are highly correlated with measures of skill such as schooling and AFQT scores. They are also highly correlated with the…

Focused on human capital, economists typically explain about half of the gender earnings gap. For a national sample of MBAs, we account for 82 percent of the gap by incorporating noncognitive skills (for example, confidence and assertiveness) and preferences regarding family, career, and jobs. Those two sources of gender heterogeneity account for…

We contrast the intergenerational mobility rates of the historically disadvantaged scheduled castes and tribes (SC/ST) in India with the rest of the workforce in terms of their education attainment, occupation choices and wages. Using survey data from successive rounds of the National Sample Survey between 1983 and 2005, we find that…

Recent studies suggest that globalization increases inequality, by increasing skilled wage premiums in developing countries. This effect may be mitigated, however, if human capital responds to global opportunities. I study how the impact of globalization varies across Indian districts with different costs of learning English. Linguistic diversity…

We show that the narrowing gender gap and the growth in earnings inequality are consistent with a simple model in which skills are heterogeneous, and the growth in skill prices has been particularly strong for skills with which women are well endowed. Empirical analysis of DOT, CPS, and NLSY79 data finds evidence to support this model. A large…

Using data from the Current Population Survey and the New Immigrant Survey, this paper examines the common perception that immigrants are concentrated in high-risk jobs for which they receive little wage compensation. Compared to native U.S. workers, non-Mexican immigrants are not at higher risk and have substantial values of statistical life.…

This paper proposes a new method for estimating family labor supply in the presence of taxes. This method accounts for continuous hours choices, measurement error, unobserved heterogeneity in tastes for work, the nonlinear form of the tax code, and fixed costs of work in one comprehensive specification. Estimated on data from the 2001 PSID, the…

Net depreciation rates in human capital are estimated from wage data on a longitudinal sample of men aged 45 to 64. The results indicate that wage rates begin to decline in the early 50s at rates under one percent annually and decline at about two percent annually after age 60. (Author)

National Longitudinal Survey of Youth data reveal that 35% of white males who left school between 1979 and 1988 returned by 1989. An estimated wage model shows that those who delay their schooling earned less than those with continuous schooling. The gap increased with the length of time before reenrollment. (SK)

Between 1973 and 1988, private sector union membership fell by 9.5 percentage points more for men than women; the gender wage gap decreased by 0.09. Unionism fell more slowly for women. Greater decline in male unionism is responsible for one-seventh of the decline in the wage gap. (SK)

We examine the impact of literacy on immigrant earnings and the sources of lower returns to education and experience among immigrants. We find that the native-born literacy distribution dominates that for immigrants. However, the two groups obtain similar returns to literacy skills, contrary to discrimination-based explanations for…

Using 1980/81 and 1990/91 census data from Australia, Canada, and the United States, we estimate the effects of time in the destination country on male immigrants' wages, employment, and earnings. We find that total earnings assimilation is greatest in the United States and least in Australia. Employment assimilation explains all of the earnings…
