We use a field experiment with 3,176 patients at 122 tuberculosis treatment clinics in India to test whether peer referrals increase screening and identification of patients with an infectious disease. Low-cost financial incentives considerably raise the probability that current patients refer...

We implemented a randomized intervention among Malawian farmers aimed at facilitating formal savings for agricultural inputs. Treated farmers were offered the opportunity to have their cash crop harvest proceeds deposited directly into new bank accounts in their own names, while farmers in the...
