We study the long-term determinants of the high rates of HIV infection in sub-Saharan Africa, particularly among women, with a focus on family structure and sexual behavior as shaped by the demographic shock following the transatlantic slave trade. First we show that, in clusters where polygyny...

Using birth certificates matched to schooling records for Florida children born 1992 - 2002, we assess whether family disadvantage disproportionately impedes the pre-market development of boys. We find that, relative to their sisters, boys born to disadvantaged families have higher rates of...

Sex ratios, i.e., relative numbers of men and women, can affect marriage prospects, labor force participation, and other social and economic variables.

This paper considers the potential relationship between providing care for grandchildren and retirement, among women nearing retirement age. Using 47,444 person-wave observations from the Health and Retirement Study (HRS), we find the arrival of a new grandchild is associated with a more than...

The big five personality traits develop over a person's lifetime. There is some suggestive evidence that major life events - such as getting married, being fired from a job, and having children - affect personality. However, these associations cannot be interpreted as causal. This is the first...

The growing gender gap in educational attainment between men and women has raised concerns that the skill development of boys may be more sensitive to family disadvantage than that of girls. Using the National Longitudinal Study of Adolescent to Adult Health (Add Health) data we find, as do...
