We argue that the environment determines life span, using historical data to show that such indicators of environmental insults in early childhood and young adulthood as quarter of birth, residence, occupation, wealth, and the incidence of specific infectious diseases affected older age...

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...

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...

I demonstrate that although socioeconomic differences in birth weight have always been" fairly small in the United States, they have narrowed since the beginning of this century. I argue" that maternal height, and therefore the mother's nutritional status during her growing years accounted for...

Functional disability (difficulty in walking , difficulty in bending, paralysis, blindness in at least one eye, and deafness in at least one ear) in the United States has fallen at an average annual rate of 0.6 percent among men age 50 to 74 from the early twentieth century to the early 1990s....

We find that veterans of the Union Army who faced greater wartime stress (as measured by higher battlefield mortality rates) experienced higher mortality rates at older ages, but that men who were from more cohesive companies were statistically significantly less likely to be affected by wartime...

Twenty-seven percent of the Union Army prisoners captured July 1863 or later died in captivity. At Andersonville the death rate may have been as high as 40 percent. How did men survive such horrific conditions? Using two independent data sets we find that friends had a statistically significant...

This paper documents differences in body size between white, black, and Indian mid-nineteenth century American men and investigates the socioeconomic and demographic determinants of frame size using a unique data set of Civil War soldiers. It finds that over time men have grown taller and...

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...

Using country- and region-level data, I investigate the effect of HIV/AIDS on fertility in Africa during 1985-2000. Results differ depending on the variation used and the estimation method. Between estimates that exploit cross-sectional variation suggest a positive significant effect of HIV/AIDS...
