The study of education in developing countries has been transformed by the rapid increase in the feasibility and prevalence of field experiments over the past 15 years. This paper comprises three main sections. First, it illustrates the very broad range of research questions regarding education...

We obtain rich measures of risk preferences of poor farmers in Vietnam, and estimate structural models that capture risk preferences over different probability levels and across different domains (gains and losses). The results break radically with the previous literature on risk preferences, in...

This paper uses a quasi-randomized field experiment in Zimbabwe to understand the impact of a large-scale intervention targeting community attitudes. I measure the impact that the program has had on attitudes, the behaviour of teachers and caregivers, and the learning and progression outcomes of...

This paper is a practical guide (a toolkit) for researchers, students and practitioners wishing to introduce randomization as part of a research design in the field. It first covers the rationale for the use of randomization, as a solution to selection bias and a partial solution to publication...

Previous research suggests that student evaluations of teacher performance are biased against women. We test this hypothesis on economics students in a randomized, double-blind experiment, set up in a natural educational setting. During the Covid-19 pandemic, teaching assistants moved online and...

This paper provides experimental evidence on the electoral effect of a large education reform in a developing democracy. Despite significantly improving school quality, the policy reduced the incumbent party's presidential vote share by 3 percentage points (10%). This does not imply that voters...

We formalize the optimal design of experiments when there is interference between units, i.e. an individual's outcome depends on the outcomes of others in her group. We focus on randomized saturation designs, two-stage experiments that first randomize treatment saturation of a group, then...

This paper formalizes the design of experiments intended specifically to study spillover effects. By first randomizing the intensity of treatment within clusters and then randomly assigning individual treatment conditional on this cluster-level intensity, a novel set of treatment effects can be...
