We identify externalities in human capital production function arising from sibling spillovers. Using regression discontinuity design generated by school-entry cutoffs and school records from one district in Florida, we find positive spillover effects from an older to a younger child in less affluent families and negative spillover effects from a younger to an older child in more affluent families. These results are consistent with direct spillovers dominating in economically disadvantaged families and with parental reinforcement in more affluent families.

Free and reduced-price meal (FRM) data are used ubiquitously to proxy for student disadvantage in education research and policy applications. The Community Eligibility Provision (CEP)—a recently-implemented policy change to the federally-administered National School Lunch Program—allows schools serving low-income populations to identify all students as FRM-eligible regardless of individual circumstances. We study the CEP’s effect on FRM eligibility as a proxy for student disadvantage, and relatedly, we examine the viability of direct certification (DC) status as an alternative disadvantage measure. Our findings on whether the CEP degrades the informational content of FRM data are mixed. At the individual level there is essentially no effect, but the CEP does meaningfully change the information conveyed by the FRM-eligible share of students in a school. Our comparison of FRM and DC data in the post-CEP era shows that these measures are similarly informative as proxies for disadvantage, despite the CEP-induced information loss in FRM data. Using both measures together can improve the identification of disadvantaged students, but only marginally.

We present evidence of a positive relationship between school starting age and children’s cognitive development from age 6 to 18 using a fuzzy regression discontinuity design and large-scale population-level birth and school data from the state of Florida. We estimate effects of being old for grade (being born in September versus August) that are remarkably stable – always around 0.2 SD difference in test scores – across a wide range of heterogeneous groups, based on maternal education, poverty at birth, race/ethnicity, birth weight, gestational age, and school quality. While the September-August difference in kindergarten readiness is dramatically different by subgroup, by the time students take their first exams, the heterogeneity in estimated effects on test scores effectively disappears. We do, however, find significant heterogeneity in other outcome measures such as disability status and middle and high school course selections. We also document substantial variation in compensatory behaviors targeted towards young for grade children. While the more affluent families tend to redshirt their children, young for grade children from less affluent families are more likely to be retained in grades prior to testing. School district practices regarding retention and redshirting are correlated with improved out- comes for the groups less likely to use those remediation approaches (i.e., retention in the case of more-affluent families and redshirting in the case of less-affluent families.) Finally, we find that very few school policies or practices mitigate the test score advantage of September born children.

We use remarkable population-level administrative education and birth records from Florida to study the role of Long-Term Orientation on the educational attainment of immigrant students living in the US. Controlling for the quality of schools and individual characteristics, students from countries with long term oriented attitudes perform better than students from cultures that do not emphasize the importance of delayed gratification. These students perform better in third grade reading and math tests, have larger test score gains over time, have fewer absences and disciplinary incidents, are less likely to repeat grades, and are more likely to graduate from high school in four years. Also, they are more likely to enroll in advanced high school courses, especially in scientific subjects. Parents from long term oriented cultures are more likely to secure better educational opportunities for their children. A larger fraction of immigrants speaking the same language in the school amplifies the effect of Long-Term Orientation on educational performance. We validate these results using a sample of immigrant students living in 37 different countries.

U.S. women graduate high school at higher rates than U.S. men, but the female-male educational advantage is larger, and has increased by more, among black and low-SES students than among white and high-SES students. We explore why boys fare worse than girls—both behaviorally and educationally— by exploiting birth certificates matched to health, disciplinary, academic, and high school graduation records for over one million children born in Florida between 1992 and 2002. We account for unobserved family heterogeneity by contrasting the outcomes of opposite-sex siblings linked to birth mothers by administrative records. Relative to their sisters, boys born to low-education and unmarried mothers, raised in low-income neighborhoods, and enrolled at poor-quality public schools have a higher incidence of absences and behavioral problems throughout elementary and middle school, exhibit higher rates of behavioral and cognitive disability, perform worse on standardized tests, and are less likely to graduate from high school. We argue that the family disadvantage gradient in the gender gap is a causal effect of the post-natal environment: family disadvantage has no relationship with the sibling gender gap in neonatal health. Although family disadvantage is strongly correlated with school and neighborhood quality, the SES gradient in the sibling gender gap is almost as large within schools and neighborhoods as between them. A surprising implication of these findings is that, relative to white children, black boys fare worse than their sisters in significant part because black children— both boys and girls—are raised in more disadvantaged family environments.

We make use of a new data resource, merged birth and school records for all children born in Florida from 1992 to 2002, to study the effects of birth weight on cognitive development from kindergarten through schooling. Using twin fixed effects models, we find that the effects of birth weight on cognitive development are essentially constant through the school career; that these effects are very similar across a wide range of family backgrounds; and that they are invariant to measures of school quality. We conclude that the effects of poor neonatal health on adult outcomes are therefore set very early.
