We consider the effects of daytime fasting by pregnant women during the lunar month of Ramadan on their children's test scores at age seven. Using English register data, we find that scores are .05 to .08 standard deviations lower for Pakistani and Bangladeshi students exposed to Ramadan in...

The United States has a long and ongoing history of racial inequality. This paper surveys the literature on one aspect of that history: long-run trends in racial differences in health. We focus on standard measures such as infant mortality and life expectancy but also consider the available data...

Sex differences in mortality (SDIM) vary over time and place as a function of social, health, and medical circumstances. The magnitude of these variations, and their response to large socioeconomic changes, suggest that biological differences cannot fully account for sex differences in survival....

This paper examines how marital and fertility patterns have changed along racial and educational lines for men and women. Historically, women with more education have been the least likely to marry and have children, but this marriage gap has eroded as the returns to marriage have changed....

This paper attempts to test whether information problems in labor markets can explain why minority or female workers are sometimes paid less than equally-qualified white male workers. In particular, the relationship between starting wages, current performance, and race and sex is studied. OLS...

In this paper we use micro-level data on employers and employees to investigate whether Affirmative Action procedures lead firms to hire minority or female employees who are less qualified than workers who might otherwise be hired. Our measures of qualifications include the educational...

This study uses a controlled experiment to explore whether there are gender differences in selecting into competitive environments across two distinct societies: the Maasai in Tanzania and the Khasi in India. One unique aspect of these societies is that the Maasai represent a textbook example of...

We examine changes in the characteristics of American youth between the late 1970s and the late 1990s, with a focus on characteristics that matter for labor market success. We reweight the NLSY79 to look like the NLSY97 along a number of dimensions that are related to labor market success,...

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 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...
