Abstract
dc:description.abstractThis thesis studies the long-term benefits of preschool interventions, the impact of promotions on heart disease, and the effects of light trucks on traffic fatalities. The first chapter examines the long-term effects of preschool interventions. Several influential experiments - Abecedarian, Perry, and Early Training - have convinced many economists that preschool interventions have super-normal returns. This chapter implements a unified statistical framework to present a de novo analysis of these experiments, focusing on core issues that received little attention in previous analyses: treatment effect heterogeneity by gender and over-rejection of the null hypothesis due to multiple inference. The primary finding of this reanalysis is that girls garnered substantial short- and long-term benefits from the interventions. However, there were no significant long-term benefits for boys. These conclusions change little when allowance is made for attrition and possible violations of random assignment. The second chapter, coauthored with Sir Michael Marmot, investigates the effect of promotions on heart disease. The positive cross-sectional relationship between socioeconomic status and health is well documented, but little evidence exists regarding the causal effect of social status on health.
