In an elementary school setting, I examine whether community-level interventions focusing on similar needs and providing… more →
A Global Regression Discontinuity Design: Theory and Application to Grade Retention Policies
Topics: MethodsWe use a marginal treatment effect (MTE) representation of a fuzzy regression discontinuity setting to propose a novel estimator. The estimator can be thought of as extrapolating the traditional fuzzy regression discontinuity estimate or as an observational study that adjusts for endogenous… more →

Sibling Spillovers May Enhance the Efficacy of Targeted School Policies
Topics: Student LearningTags: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… more →
The Effects of Middle School Remediation on Postsecondary Success: Regression Discontinuity Evidence from Florida
Topics: Student LearningHigh school graduation rates in the United States are at an all-time high, yet many of these graduates are deemed not ready for postsecondary coursework when they enter college. This study examines the short-, medium-, and long-term effects of remedial courses in middle school using a regression… more →
Diversity in Schools: Immigrants and the Educational Performance of U.S. Born Students

This research question is complicated by substantial school selection of US-born students, especially among… more →
Examining the Educational Spillover Effects of Severe Natural Disasters: The Case of Hurricane Maria
This study examines the effects of internal migration driven by severe natural disasters on host communities, and the mechanisms behind these effects, using the large influx of migrants into Florida public schools after Hurricane Maria. I find adverse effects of the influx in the first year on… more →
