In 1996, following an epidemic, Pfizer tested a new drug on 200 children in Muslim Nigeria. 11 children died while others were disabled. We study the effects of the disclosure, in 2000, of the deaths of Muslim children in the Pfizer trials on vaccine compliance among Muslim mothers. Muslim...

Mental health disorders account for a significant share of the overall global disease burden. The economic losses from such disorders are staggeringly large, particularly in low-income countries, where people are faced with several unexpected shocks. We test whether improved communication can...

Governments in many low- and middle-income countries are developing health insurance products as a complement to tax-funded, subsidized provision of health care through publicly operated facilities. This paper discusses two rationales for this transition. First, health insurance would boost...

Bias among health care providers can lead to poor-quality care and poor health outcomes, and it can exacerbate disparities. We use a randomized controlled trial to evaluate an intervention to reduce family planning provider bias towards young women in 227 clinics in Tanzania, Burkina Faso, and...

Building on prior evidence that mothers often have a stronger preference for spending on children than fathers do, we use a randomized experiment to evaluate the impacts of a communication training program for mothers on child health in Uganda. The hypothesis is that the training will enable...

We examine the impact of a randomized therapy intervention on Nepali adolescents at risk of school dropout. Our study is the largest of its kind (N = 1,707) and is novel in that participation does not require a preexisting diagnosis. Ninety percent of those offered therapy participated, with...

How do aspirations influence investment decisions for people living in poverty? Does this change as peoples economic conditions improve? To answer these questions, we design a workshop teaching techniques to raise aspirations and plan to achieve them. We cross-randomise this with large...

In recent years, the psychological causes and consequences of poverty have received renewed attention from scientists and policymakers. In this review, we summarize new developments in this literature. First, we discuss advances in our understanding of the relationship between income and...

We revisit two clinical trials that randomized depressed adults in India (n=775) to a brief course of psychotherapy or a control condition. Four to five years later, the treatment group was 11 percentage points less likely to be depressed than the control group. The more effective intervention...
