A growing literature examining labor market returns to college major is motivated by large returns to skill. Prior research focuses on mean effects rather than earnings growth and variability. Using administrative data from Texas, we find that mean differences mask important features of the returns to college majors. First, earnings growth varies across fields. Second, there is considerable effect heterogeneity across workers. Third, major choice affects earnings variability within workers over time. We use our results to simulate a lifecyle utility model and compare mid-career utility and mean earnings returns across fields while highlighting the important role of risk preferences.

We estimate the impact of incentive strength on achievement under a group-based teacher incentive pay program. The system provides variation in the share of students in a subject-grade that a teacher instructs, which proxies for incentive strength. We find that achievement on incentivized exams, but not nonincentivized exams, improves when incentives strengthen. For the incentivized exams, we find that effects fade out monotonically as a teacher's portion of the group increases to between 20 and 30 percentage and are larger for teachers with low-achieving students. Calculations based off these estimates show modest positive effects of the program overall.

This paper uses wealth changes driven by housing market variation to estimate the effect of family resources on fertility decisions. Using data from the Panel Study of Income Dynamics, we show that a $100,000 increase in housing wealth among home owners causes a 16% to 18% increase in the probability of having a child. There is no evidence of an effect of MSA-level housing price growth on the fertility of renters, however. We also present evidence that housing wealth growth increases total fertility and that the responsiveness of fertility to housing wealth has increased over time, commensurate with the recent housing boom.
