Should I Stay or Should I go? Neighbors' Effects on University Enrollment (Revise and Resubmit, AEJ: Applied Economics) CEP Discussion Paper Version

This paper investigates whether the decision to attend university is affected by university enrollment of close neighbors. I create a unique dataset combining detailed geographic information and educational records from different public agencies in Chile, and exploit the quasi-random variation generated by student loans eligibility rules. I find that close neighbors have a large and significant impact on university enrollment, especially in areas with low exposure to university and among individuals who are more likely to interact: the effect decreases both with geographic and social distance and is weaker for individuals who have spent less time in the neighborhood. I also show that the rise in enrollment translates into higher university completion rates. These effects are mediated by an increase in applications rather than by an improvement in academic performance. This set of results suggests that policies that expand access to university generate positive spillovers on close peers of the direct beneficiaries.

O Brother, Where Start Thou? Sibling Spillovers on College and Major Choice in Four Countries (Forthcoming, The Quarterly Journal of Economics) with A. Altmejd, M. Drlje, J. Goodman, M. Hurwitz, D. Kovac, C. Mulhern, C. Neilson and J. Smith. IRS Princeton University Working Paper , Online Appendix

Family and social networks are widely believed to influence important life decisions but causal identification of those effects is notoriously challenging. Using data from Chile, Croatia, Sweden, and the United States, we study within-family spillovers in college and major choice across a variety of national contexts. Exploiting college-specific admissions thresholds that directly affect older but not younger siblings’ college options, we show that in all four countries a meaningful portion of younger siblings follow their older sibling to the same college or college-major combination. Older siblings are followed regardless of whether their target and counterfactual options have large, small or even negative differences in quality. Spillover effects disappear, however, if the older sibling drops out of college, suggesting that older siblings’ college experiences matter. That siblings influence important human capital investment decisions across such varied contexts suggests that our findings are not an artifact of particular institutional detail but instead a more generalizable description of human behavior. Causal links between the postsecondary paths of close peers may partly explain persistent college enrollment inequalities between social groups and suggests that interventions to improve college access may have multiplier effects.

It's time to learn: School Institutions and Returns to Instruction Time (Forthcoming, Economics of Education Review) with Giulia Bovini. #Data #Code

This paper investigates whether the effects of a reform that substantially increased daily instruction time in Chilean primary schools vary depending on school institutions. Focusing on incumbent students and exploiting an IV strategy, we find that longer daily schedules increase reading scores at the end of fourth grade and that the benefits are greater for pupils who began primary education in no-fee charter schools rather than in public schools. We provide evidence that these two types of publicly subsidized establishments, which cater to similar students but differ in their degree of autonomy, expand the teaching input in different ways: in order to provide the additional instruction time, no-fee charter schools rely more on hiring new teachers and less on increasing teachers’ working hours than public schools do.

Recidivism and Neighborhood Institutions: Evidence from the Rise of the Pentecostal Church in Chile (Draft coming soon)
with Jorge Garcia-Hombrados

Using rich administrative data from Chile, we investigate how the context to which young inmates are released affects their probability of returning to prison. In a difference-in-differences setting, we exploit variation generated by the opening of new Pentecostal churches and compare former prisoners from the same neighborhood who live at different distances from the new church. We find that the opening of a new Pentecostal church significantly reduces recidivism among individuals who served sentences related to property crimes; the effects are smaller and less precise for more severe crimes. We discuss three broad classes of mechanisms and argue that our results are more consistent with a decrease in the benefits of committing a crime driven by access to better and wider networks.
