Family and social networks are widely believed to influence important life decisions but identifying their causal effects is notoriously difficult. Using admissions thresholds that directly affect older but not younger siblings' college options, we present evidence from the United States, Chile,...

This paper estimates the impact of the College Level Examination Program (CLEP), an exam that offers credit for student competency in a content area in lieu of completing a course. Using a regression discontinuity design, we find that passing a CLEP exam leads to a 5.5 percent increase in degree...

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...

We demonstrate that heat inhibits learning and that school air-conditioning mitigates 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 heat...

NEBULA is a proposal for a Future Internet Architecture. It is based on the assumptions that: (1) cloud computing will comprise an increasing fraction of the application workload offered to an Internet, and (2) that access to cloud computing resources will demand new architectural features from...

This paper estimates the impact of the College Level Examination Program (CLEP) examination, a college-level exam that offers credit for student mastery of a content area in lieu of completing a course. Using a regression discontinuity design, we find that passing a CLEP exam leads to a 17...

Using the universe of SAT score sends to colleges and the exact date on which these scores are sent, we estimate how students responded to the release of the U.S. Department of Education's College Scorecard in September 2015. We find that data on annual cost and graduation rate, both of which...

Mapping continuous raw scores from millions of Advanced Placement examinations onto the 1 to 5 integer scoring scale, we apply a regression discontinuity design to understand how students' choice of college major is impacted by receiving a higher integer score despite similar exam performance to...
