Does Relative Performance Feedback Improve Academic Outcomes? Evidence from a Randomised Controlled Trial in a Spanish University
The effects of relative performance feedback on student achievement remain contested in the economics of education literature. Some studies find that providing students with information about their standing relative to peers improves academic outcomes, while others show negative effects driven… more →
From Pilot to Policy: Experimental Evidence from Scaling Online Tutoring
We study a randomized controlled trial of an online mathematics tutoring program scaled from a successful pilot and implemented entirely by regional education authorities in Spain, using interim public-school teachers rather than specially recruited tutors. Assignment to tutoring increased end… more →
Sibling Spillovers and Free Schooling
We use administrative data to measure sibling spillovers on academic performance before and after the introduction of Free Secondary Education (FSE) in Tanzania. Prior to FSE, students whose older siblings narrowly passed the secondary school entrance exam were less likely to go to secondary… more →
Causal Returns to Education
Using 182 estimates from 140 studies in 55 countries, this paper compares ordinary least squares (OLS) and instrumental variables (IV) estimates of the private returns to schooling. IV returns average 9.7 percent—38 percent higher than OLS—and exceed OLS in nearly 80 percent of cases, with the… more →
Bridging Literacy Gaps: The Impact of AI-Driven Personalised Learning on Reading Skills and Educational Equity
Persistent literacy skills deficits hinder educational attainment, limit labour market opportunities, and exacerbate socioeconomic inequalities. This paper evaluates the causal effect of an AI-driven Computer-Assisted Learning (CAL) program implemented by the Government of Madrid, which features… more →
Implementation Matters: Generalizing Treatment Effects in Education
Targeted instruction is one of the most effective educational interventions in low- and middle-income countries, yet reported impacts vary by an order of magnitude. We study this variation by aggregating evidence from prior randomized trials across five contexts, and use the results to inform a… more →
