Abstract
Personality, IQ, and Lifetime Earnings: In this paper, I show that even in a group of
high-IQ men and women, lifetime earnings are substantially influenced by their personality traits and education. Personality traits directly affect men's earnings, with effects only developing fully after age 30. Furthermore, these effects play a much larger role for the earnings of more educated men. Personality and IQ also influence earnings indirectly through education, which has sizeable positive rates of return for men in this sample. Surprisingly, education and personality skills do not always raise the family earnings of women in this cohort, as women with very high education and IQ are less likely to marry, and thus have less income through their husbands.
Effectiveness of Chicago Child Parent Centers in Producing Young-Adult Out-
comes: We reanalyze a study that follows children who participated in Chicago Child Parent Centers (CPCs), an early childhood education program, and a control group of children who did not. The sample has a quasi-experimental structure, to which we add information about children's birth tract, including neighborhood quality. We incorporate the distance to centers as determinants of CPC participation, to partially address selection bias. We define an estimator that is closer to the true treatment effect on the treated than the adjusted mean
comparisons presented in previous analyses, and corroborate evidence for positive effects of the program on economic outcomes, and several educational outcomes, especially for men. Furthermore, we study whether the program is equally successful in the most disadvantaged neighborhoods, and find that the efficacy of the program is generally reduced by low neighborhood quality.
