Researchers tested the effect of a basic CCT program, as well as two complementary interventions, on households’ vulnerability to irregular weather patterns. Providing households with vocational training or capital grants to generate non-agricultural income helps improve consumption and resilience to weather shocks.

Distributing water cisterns in northeast Brazil led to fewer requests for private benefits from local politicians and fewer votes for incumbent mayors, who typically have more resources to engage in clientelism. Marco Gonzalez-Navarro and J-PAL's Latin America & Caribbean office are now working with the Climate Policy Initiative to support the Ministry of Social Development to design and implement an evaluation of the second deployment of cisterns.

In Uganda, researchers studied the demand for rainwater storage devices, the effectiveness of various marketing strategies in promoting them, and their impact on indicators such as school attendance and women’s participation in the labor market.

Researchers conducted a randomized evaluation to test the impact of lottery-based financial awards given to young individuals who tested STI-negative on their likelihood of contracting HIV and engaging in risky sexual behavior. The intervention provided frequent rewards at short intervals to bring the benefits of safe sex closer to the present and used a lottery design to try to target higher-risk individuals. Lottery-based financial incentives reduced the prevalence and incidence of HIV by 12 percent and 21 percent respectively, and their impact was largest among individuals with a high tolerance for risk.

In Bihar, India, researchers examined how double fortified salt could be most effectively priced, marketed, and distributed, in order to have the greatest impact on a range of health, education, and economic outcomes.

Diabetes is one of the most prevalent diseases in the United States and is closely linked to food insecurity. Researchers evaluated the impact of an intensive food-as-medicine program that provides fresh food and diabetes education on health and health care utilization for individuals experiencing both diabetes and food insecurity. Researchers found that the program had high levels of engagement. Patients in both the program and the comparison group saw improvements in health outcomes over time, but there were no significant differences between groups.

The researcher conducted a randomized evaluation in rural Tanzania to determine the impact of an SMS-based messaging app that connects agricultural workers and employers on wages. Results found that the SMS-based messaging app reduced wage spread within villages–meaning employers paid a wage closer to the average wage.

In northern Nigeria, researchers evaluated the impact of three community-based interventions designed to enhance uptake of maternal and child health services: a community health worker program, health educators with the provision of safe birth kits, and health educators with community dramas. While the community health educators increased utilization of maternal and infant care, health practices, and knowledge, none of the interventions improved maternal or child health outcomes.

Researchers introduced four savings devices to estimate the relative importance of different potential barriers to health savings. Results indicate that just providing a safe place to keep money led to a large increase in health savings. These results suggest that simply labeling funds for a specific purpose can help households save and invest more.

In Lusaka, Zambia, researchers compared the effect of financial and non-financial reward schemes on sales of female condoms. They found that non-financial incentives were more effective than financial rewards at motivating hair stylists to sell female condoms to their customers.

Women who received private access to vouchers for contraceptives were more likely to take up and use contraception, compared to women whose husbands were involved in the voucher program.

Researchers are testing whether giving vendors money to pay off their outstanding debts or offering financial literacy trainings can help break these borrowers' cycles of debt.

Researchers assessed whether the provision of health training alongside microfinance services impacted the health or financial behavior of Peruvian microcredit clients. They found that additional health training affected neither.

Researchers conducted a randomized evaluation of a bundled microcredit and health education program, delivered both to mixed-gender and female-only loan groups in Benin, to evaluate its impacts on health knowledge, health behaviors, and social outcomes. The integrated package of group microcredit and health education led to gains in women’s knowledge of both malaria and HIV/AIDS, but those gains did not translate into improvements in health behaviors.

In an ongoing evaluation, researchers are studying the relationship between teacher and student motivation, family participation, and student achievement in rural non-formal education (NFE) centers.
