Between the early 1980s and 2002, both the prevalence of obesity and the number of beneficiaries of the Social Security Disability Insurance program doubled. We test whether these trends are related; specifically, we test whether obesity causes disability and movement onto the disability rolls.

We estimate models of instrumental variables using two nationally representative datasets: the Panel Survey of Income Dynamics and the National Longitudinal Survey of Youth, 1979 Cohort. The results are mixed but we find evidence that weight increases the probability of health-related work limitations and the probability of receiving disability related income. Our results suggest that the failure to treat obesity as endogenous leads to dramatic underestimates of the link between obesity and disability outcomes.

The purpose of this paper...is to examine changes in the consequences of teenage childbearing for children over birth cohorts of young women and historical periods. Are there differences in the effects of timing of childbearing on children's achievements, by whether the first birth occurred in the 1970s, 1980s, or 1990s? Are there differences in the effects of timing of childbearing on the schooling of young women who had a first birth in the late 1970s compared with those who bore a child in the late 1980s? This analysis focuses on examining period differences in the consequences of teen childbearig using two data sets, the Panel Study of Income Dynamics (PSID) and the National Longitudinal Survey of Youth (NLSY). The NLSY has been used extensively to document the consequences of teen childbearing for young women. It, therefore, represents the "gold standard." However, it represents a single birth cohort of young women. The PSID has also been used to look at teen childbearing (Astone & Upchurch, 1994; Hoffman, Foster & Furstenberg, 1993). While it represents a large number of birth cohorts of women, a smaller number of women compromise each cohort. To the extent that these two data sets provide similar pictures of the same cohort, the PSID can then be used to depict period trends in the effects of teen childbearing on children. Thus, the first goal is to compare the effects of a teen birth on children using both data sets. The second goal is to show the trends over time in the effects of teen childbearing on children's achievement. This will be done by examining the effect on children's achievement and behavior of interacting teen childbearing with period, using the PSID.
