The Unwavering SES Achievement Gap: Trends in U.S. Student Performance
Concerns about the breadth of the U.S. income distribution and limited intergenerational mobility have led to a focus on educational achievement gaps by socio-economic status (SES). Uintertemporally linked assessments from NAEP, TIMSS, and PISA, we trace the achievement of U.S.
Elusive Longer-Run Impacts of Head Start: Replications Within and Across Cohorts
Using an additional decade of CNLSY data, this study replicated and extended Deming’s (2009) evaluation of Head Start’s life-cycle skill formation impacts in three ways. Extending the measurement interval for Deming’s adulthood outcomes, we found no statistically significant… more →
Take Two! SAT Retaking and College Enrollment Gaps
Only half of SAT-takers retake the exam, with even lower retake rates among low income and underrepresented minority (URM) students. We exploit discontinuous jumps in retake probabilities at multiples of 100, driven by left-digit bias, to estimate retaking’s causal effects. Retaking… more →
Heat and Learning
We demonstrate that heat inhibits learning and that school air-conditioning may mitigate this effect. Student fixed effects models using 10 million PSAT-retakers show hotter school days in years before the test reduce scores, with extreme heat being particularly damaging. Weekend and summer… more →
