This paper examines the links between the disease environment around the time of a woman's birth, and her health at the time she delivers her own infant. Our results suggest that exposure to disease in early childhood significantly increases the incidence of diabetes in the population of future...

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...

Young (2005) argues that HIV related population declines reinforced by the fertility response to the epidemic will lead to higher capital-labor ratios and to higher per capita incomes in the affected countries of Africa. Using household level data on fertility from South Africa and relying on...

We use the Islamic holy month of Ramadan as a natural experiment in fasting and fetal health. In Michigan births 1989-2006, we find prenatal exposure to Ramadan among Arab mothers results in lower birthweight and reduced gestation length. Exposure to Ramadan in the first month of gestation is...

Birth weight has emerged as the leading indicator of infant health and welfare and the central focus of infant health policy. This is because low birth weight (LBW) infants experience severe health and developmental difficulties that can impose enormous costs on society. But would the prevention...

Patients who receive more hospital treatment tend to have worse underlying health, confounding estimates of the returns to such care. This paper compares the costs and benefits of extending the length of hospital stay following delivery using a discontinuity in stay length for infants born close...

The historical pattern of the demographic transition suggests that fertility declines follow mortality declines, followed by a rise in human capital accumulation and economic growth. The HIV/AIDS epidemic threatens to reverse this path. A recent paper by Young (2005), however, suggests that...

This paper estimates the effects of maternal malnutrition exploiting the 1959-1961 Chinese famine as a natural experiment. In the 1% sample of the 2000 Chinese Census, we find that fetal exposure to acute maternal malnutrition had compromised a range of socioeconomic outcomes, including:...

We estimate marginal returns to medical care for at-risk newborns by comparing health outcomes and medical treatment provision on either side of common risk classifications, most notably the "very low birth weight" threshold at 1500 grams. First, using data on the census of US births in...

We examine the role of changing mortality in explaining the rise of retirement over the course of the 20th century. We construct a model in which individuals make labor/leisure choices over their lifetimes subject to uncertainty about their date of death. In an environment in which mortality is...
