Birth order has been found to have a surprisingly large influence on educational attainment, yet much less is known about the role of birth order on delinquency outcomes such as disciplinary problems in school, juvenile delinquency, and adult crime: outcomes that carry significant negative externalities. This paper uses particularly rich datasets from Denmark and the state of Florida to examine these outcomes and explore potential mechanisms. Despite large differences in environments across the two areas, we find remarkably consistent results: in families with two or more children, second-born boys are on the order of 20 to 40 percent more likely to be disciplined in school and enter the criminal justice system compared to first-born boys even when we compare siblings. The data allow us to examine a range of potential mechanisms, and the evidence rules out differences in health at birth and the quality of schools chosen for children. We do find that parental time investment measured by time out of the labor force is higher for first-borns at ages 2-4, suggesting that the arrival of a second-born child extends early-childhood parental investments for first-borns.

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.

Analyzing Florida birth certificates matched to school records, we document that the female advantage in childhood behavioral and academic outcomes is driven by gender gaps at the extremes of the outcome distribution. Using unconditional quantile regression, we investigate whether family socioeconomic status (SES) differentially affects the lower tail outcomes of boys. We find that the differential effects of family SES on boys' outcomes are concentrated in the parts of the distribution where the gender gaps are most pronounced. Accounting for the disproportionate effects of family environment on boys at the tails substantially narrows the gender gap in high school dropout.

Public policies often target individuals but within-family externalities of such interventions are understudied. Using a regression discontinuity design, we document how a third grade retention policy affects both the target children and their younger siblings. The policy improves test scores of both children while the spillover is up to 30% of the target child effect size. The effects are particularly pronounced in families where one of the children is disabled, for boys, and in immigrant families. Candidate mechanisms include improved classroom inputs and parental school choice.

Using spatial and temporal variation in openings of fast food restaurants in Norway between 1980 and 2007, we study the effects of changes in the supply of high caloric nutrition on the health and cognitive ability of young adult males. Our results indicate that exposure to these establishments during childhood and adolescence increases BMI and has negative effects on cognition. Heterogeneity analysis does not reveal meaningful differences in the effects across groups, including for those with adverse prenatal health or high paternal BMI, an exception being that cognition is only affected by exposure at ages 0--12 and this effect is mediated by paternal education.

Thanks to extraordinary and exponential improvements in data storage and computing capacities, it is now possible to collect, manage, and analyze data in magnitudes and in manners that would have been inconceivable just a short time ago. As the world has developed this remarkable capacity to store and analyze data, so have the world's governments developed large-scale, comprehensive data files on tax programs, workforce information, benefit programs, health, and education. While these data are collected for purely administrative purposes, they represent remarkable new opportunities for expanding our knowledge. This chapter describes some of the benefits and challenges associated with the use of administrative data in education research. We also offer specific case studies of data that have been developed in both the Nordic countries and the United States, and offer an (incomplete) inventory of data sets used by social scientists to study education questions on every inhabited continent on earth.

We estimate health associations across generations and dynasties using information on healthcare visits from administrative data for the entire Norwegian population. A parental mental health diagnosis is associated with a 9.3 percentage point (40%) higher probability of a mental health diagnosis of their adolescent child. Intensive margin physical and mental health associations are similar, and dynastic estimates account for about 40% of the intergenerational persistence. We also show that a policy targeting additional health resources for the young children of adults diagnosed with mental health conditions reduced the parent-child mental health association by about 40%.

We present evidence of a positive relationship between school starting age and children's cognitive development from age 6 to 15 using a regression discontinuity design and large-scale population-level birth and school data from the state of Florida. We estimate effects of being relatively old for grade (being born in September versus August) that are remarkably stable - always just 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 effectively disappears. We 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 outcomes 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.) We also study college and juvenile detention outcomes using administrative data from a large Florida school district, and show that being an older age at school entry increases children's college attainment and reduces the likelihood of being incarcerated for juvenile crime.

The past century witnessed a dramatic improvement in public health, the rise of modern medicine, and the transformation of the hospital from a fringe institution to one essential to the practice of medicine. In this paper, we explore how access to the hospital and modern medicine affects mortality. We do so by leveraging a combination of novel data and a unique quasi-experiment: a large-scale hospital modernization program introduced by The Duke Endowment in the early twentieth century. The Endowment helped communities build and expand hospitals, obtain state-of-the-art medical technology, attract qualified medical personnel, and refine management practices. We find that access to a Duke-supported hospital reduced infant mortality by 10%, saving one life for every $20,000 (2017 dollars) spent. Effects were larger for Black infants (16%) than for White infants (7%), implying a reduction in the Black-White infant mortality gap by one-third. We show that the effect of Duke support persisted into later life with a 9% reduction in mortality between the ages of 56 and 65. We further provide evidence on the mechanisms that enabled these effects, finding that Endowment-supported hospitals attracted higher-quality physicians and were better able to take advantage of new medical innovations.

Using a rich dataset that merges student-level school records with birth records, and a student fixed effect design, we explore how the massive scale-up of a Florida private school choice program affected public school students' outcomes. Expansion of the program produced modestly larger benefits for students attending public schools that had a larger initial degree of private school options, measured prior to the introduction of the voucher program. These benefits include higher standardized test scores and lower absenteeism and suspension rates. Effects are particularly pronounced for lower-income students, but results are positive for more affluent students as well.
