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...

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...

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....

I survey the evidence on patterns in U.S. high school graduation rates over the period 1970-2010 and report the results of new research conducted to fill in holes in the evidence. I begin by pointing out the strengths and limitations of existing data sources. I then describe six striking...

A growing literature establishes that high quality early childhood interventions targeted toward disadvantaged children have substantial impacts on later life outcomes. Little is known about the mechanisms producing these impacts. This paper uses longitudinal data on cognitive and personality...

Employing original, representative survey data, we document that cognitive, interpersonal and physical job task demands can be measured with high validity using standard interview techniques. Job tasks vary substantially within and between occupations, are significantly related to workers'...

Although the debate over Affirmative Action is both high-profile and high-intensity, neither side's position is based on a well-established set of research findings. Economics provides an extensive, well-known literature on which to draw regarding the existence and extent of labor market...

We use data from a survey of employers to investigate how Affirmative Action in recruiting and hiring influences hiring practices, personnel policies, and ultimately employment outcomes. Our results show that Affirmative Action increases the number of recruitment and screening practices used by...
