We report on a randomized field experiment using price incentives to address both economic and gender inequality in land tenure formalization. During the 1990s and 2000s, nearly two dozen African countries proposed de jure land reforms extending access to formal, freehold land tenure to millions...

Child marriage is associated with bad outcomes for women and girls. Although many countries have raised the legal age of marriage to deter this practice, the incidence of early marriage remains stubbornly high. We develop a simple model to explain how enforcing minimum age-of-marriage laws...

Regulatory pressure on international banks to fight money laundering (ML) and terrorist financing (TF) increased substantially in the past decade. At the same time there has been a rise in the number of complaints of banks denying transactions or closing the accounts of customers either based in...

A large empirical literature has shown that user fees significantly deter public service utilization in developing countries. While most of these results reflect partial equilibrium analysis, we find that the nationwide abolition of public school fees in Kenya in 2003 led to no increase in net...

In this paper we examine how policymakers and practitioners should interpret the impact evaluation literature when presented with conflicting experimental and non-experimental estimates of the same intervention across varying contexts. We show three things. First, as is well known,...

The recent wave of randomized trials in development economics has provoked criticisms regarding external validity. We investigate two concerns — heterogeneity across beneficiaries and implementers — in a randomized trial of contract teachers in Kenyan schools. The intervention, previously...

Public employees in many developing economies earn much higher wages than similar private-sector workers. These wage premia may reflect an efficient return to effort or unobserved skills, or an inefficient rent causing labor misallocation. To distinguish these explanations, we exploit the Kenyan...

Internationally comparable test scores play a central role in both research and policy debates on education. However, the main international testing regimes, such as PISA, TIMSS, or PIRLS, include very few low-income countries. For instance, most countries in Southern and Eastern Africa have...

Since 2001, an aid consortium known as Gavi has accounted for over half of vaccination expenditure in the 75 eligible countries with an initial per capita GNI below $1,000. Regression discontinuity (RD) estimates show aid significantly displaced other immunization efforts and failed to increase...

The lack of reliable development statistics for many poor countries has led the U.N. to call for a “data revolution” (United Nations, 2013). One fairly narrow but widespread interpretation of this revolution is for international aid donors to fund a coordinated wave of household surveys...
