Improving Education in the Developing World: What Have We Learned from Randomized Evaluations?

Across a range of contexts, reductions in education costs and provision of subsidies can boost school participation, often dramatically. Decisions to attend school seem subject to peer effects and time-inconsistent preferences. Merit scholarships, school health programs, and information about returns to education can all cost-effectively spur school participation. However, distortions in education systems, such as weak teacher incentives and elite-oriented curricula, undermine learning in school and much of the impact of increasing existing educational spending. Pedagogical innovations designed to address these distortions (such as technology-assisted instruction, remedial education, and tracking by achievement) can raise test scores at a low cost. Merely informing parents about school conditions seems insufficient to improve teacher incentives, and evidence on merit pay is mixed, but hiring teachers locally on short-term contracts can save money and improve educational outcomes. School vouchers can cost-effectively increase both school participation and learning.
