To assess ways to achieve widespread health insurance coverage with financial solvency in developing countries, we designed a randomized experiment involving almost 6,000 households in Indonesia who are subject to a nationally mandated government health insurance program. We assessed several...

We examine the impact of criminalizing sex work, exploiting an event in which local officials unexpectedly criminalized sex work in one district in East Java, Indonesia, but not in neighboring districts. We collect data from female sex workers and their clients before and after the change. We...

In developing countries, identifying the poor for redistribution or social insurance is challenging because the government lacks information about people's incomes. This paper reports the results of a field experiment conducted in 640 Indonesian villages that investigated two main approaches to...

Outsourcing government service provision to private firms can improve efficiency and reduce rents, but there are risks that non-contractible quality will decline and that reform could be blocked by vested interests exactly where potential gains are greatest. We examine these issues by conducting...

We investigate the mechanisms underlying health promotion campaigns designed to eliminate open defecation in at-scale randomized field experiments in four countries: India, Indonesia, Mali, and Tanzania. Health promotion works through a number of mechanisms, including: providing information on...

Can governments improve aid programs by providing information to beneficiaries? In our model, information can change how much aid citizens receive as they bargain with local officials who implement national programs. In a large-scale field experiment, we test whether mailing cards with program...

We investigate whether experiencing a natural disaster affects risk-taking behavior. We conduct standard risk games (using real money) with randomly selected individuals in rural Indonesia. We find that individuals who recently suffered a flood or earthquake exhibit more risk aversion....

Economic theory suggests that, when designing aid programs, ordeal mechanisms that impose differential costs for rich and poor can induce self-selection and hence improve targeting ("self-targeting"). We first re-examine this theory and show that ordeal mechanisms may actually have theoretically...

This paper investigates the impact of elite capture on the allocation of targeted government welfare programs in Indonesia, using both a high-stakes field experiment that varied the extent of elite influence and non-experimental data on a variety of existing government transfer programs....

We use unique data from 600 Indonesian communities on what individuals know about the poverty status of others to study how network structure influences information aggregation. We develop a model of semi-Bayesian learning on networks, which we structurally estimate using within-village data....
