Education and Labor Market Consequences of Teenage Childbearing: Evidence Using the Timing of Pregnancy Outcomes and Community Fixed Effects

The question of whether giving birth as a teenager has negative economic consequences for the mother remains controversial despite substantial research. In this paper, we build upon existing literature, especially the literature that uses the experience of teenagers who had a miscarriage as the appropriate comparison group. We show that miscarriages are not random events, but rather are likely correlated with (unobserved) community-level factors, casting some doubt on previous findings. Including community-level fixed effects in our specifications lead to important changes in our estimates. By making use of information on the timing of miscarriages as well as birth control choices preceding the teenage pregnancies we construct more relevant control groups for teenage mothers. We find evidence that teenage childbearing likely reduces the probability of receiving a high school diploma by 5 to 10 percentage points, reduces annual income as a young adult by $1,000 to$2,400, and may increase the probability of receiving cash assistance and decrease years of schooling.teen pregnancy, economic consequences, human capital

The Effect of Adolescent Health on Educational Outcomes: Causal Evidence using ‘Genetic Lotteries’ between Siblings

There has been growing interest in using specific genetic markers as instrumental variables in attempts to assess causal relationships between health status and socioeconomic outcomes, including human capital accumulation. In this paper we use a combination of family fixed effects and genetic marker instruments to show strong evidence that inattentive symptoms of ADHD in childhood and depressive symptoms as an adolescent are linked with years of completed schooling. Our estimates suggest that controlling for family fixed effects is important but these strategies cannot fully account for the endogeneity of poor mental heath. Finally, our results demonstrate that the presence of comorbid conditions present immense challenges for empirical studies that aim to estimate the impact of specific health conditions.Education Outcomes, Depression, Genetic Markers, ADHD, Obesity, Family Fixed Effects, and Instrumental Variables

Cumulative Effects of Job Characteristics on Health

We present what we believe are the best estimates of how job characteristics of physical demands and environmental conditions affect individual’s health. Five-year cumulative measures of these job characteristics are used to reflect findings in the physiologic literature that cumulative exposure is most relevant for the impact of hazards and stresses on health. Using data from the Panel Study of Income Dynamics we find that individuals who work in jobs with the ‘worst’ conditions experience declines in their health, although this effect varies by demographic group. For example, for non-white men, a one standard deviation increase in cumulative physical demands decreases health by an amount that offsets an increase of two years of schooling or four years of aging. Job characteristics are found more detrimental to the health of females and older workers. These results are robust to inclusion of occupation fixed effects, health early in life and lagged health.Health, occupational characteristic

Using Genetic Lotteries within Families to Examine the Causal Impact of Poor Health on Academic Achievement

While there is a well-established, large positive correlation between mental and physical health and education outcomes, establishing a causal link remains a substantial challenge. Building on findings from the biomedical literature, we exploit specific differences in the genetic code between siblings within the same family to estimate the causal impact of several poor health conditions on academic outcomes. We present evidence of large impacts of poor mental health on academic achievement. Further, our estimates suggest that family fixed effects estimators by themselves cannot fully account for the endogeneity of poor health. Finally, our sensitivity analysis suggests that these differences in specific portions of the genetic code have good statistical properties and that our results are robust to reasonable violations of the exclusion restriction assumption.

Estimating Causal Effects of Early Occupational Choice on Later Health: Evidence Using the PSID

In this paper, we provide some of the first empirical evidence of whether early occupational choices are associated with lasting effects on health status, affecting individuals as they age. We take advantage of data on occupational histories available in the Panel Study of Income Dynamics (PSID) to examine this issue. To the PSID data, we merge historical Census data that reflect the labor market conditions when each individual in the PSID made his first occupational choice. These data on labor market conditions (e.g. state-level share of blue collar workers) allow us to instrument for occupational choice in order to alleviate endogeneity bias. We use parental occupation as additional instruments. Since our instruments may have indirect effects on later health, we also control for respondent’s pre-labor market health, education and several family and state background characteristics in order to make the instruments more plausibly excludable. We find substantial evidence that a blue collar occupation at labor force entry is associated with decrements to later health status, ceteris paribus. These health effects are larger after controlling for endogeneity and are similar across sets of instruments. We also find differences in the effects of occupation by gender, race, and age.

Tobacco Use, Taxation and Self Control in Adolescence

Recent literature has suggested that higher taxes on addictive goods could increase welfare by assisting individuals with self control problems and trouble resisting 'temptation’. In contrast, if individuals continue to use despite increased prices, taxation may serve to reduce the welfare of these individuals while providing no benefits in managing self control nor mitigating externalities. We use data on adolescents from the National Longitudinal Study of Adolescent Health (Add Health) to examine the impact of tobacco taxes on smoking. To account for unobserved heterogeneity in response to taxes we estimate finite mixture models, positing two types of individuals with differential responses to taxes. We find evidence of differential price elasticity for tobacco use across the adolescents groups, and show that individuals with low self control or high discount rates are largely unresponsive to cigarette price. Those who have the least willpower may need the most help in quitting but are unresponsive to taxes, suggesting that policies other than taxation may be needed to reduce adolescent tobacco use.

Cumulative Effects of Job Characteristics on Health

We examine whether the job characteristics of physical demands and environmental conditions affect individual’s health. Five-year cumulative measures of these job characteristics are used to reflect findings in the biologic and physiologic literature that indicate that cumulative exposure to hazards and stresses harms health. To create our analytic sample, we merge job characteristics from the Dictionary of Occupational Titles with the Panel Study of Income Dynamics dataset. We control for early and lagged health measures and a set of pre-determined characteristics to address concerns that individuals self-select into jobs. Our results indicate that individuals who work in jobs with the ‘worst’ conditions experience declines in their health, though this effect varies by demographic group. For example, for non-white men, a one standard deviation increase in cumulative physical demands decreases health by an amount that offsets an increase of two years of schooling or four years of aging. We also find evidence that job characteristics are more detrimental to the health of females and older workers. Finally, we report suggestive evidence that earned income, another job characteristic, partially cushions the health impact of physical demands and harsh environmental conditions for workers. These results are robust to inclusion of occupation fixed effects.
