A study conducted in Ghana over 15 years evaluated the benefits of secondary school scholarships on both education and health outcomes.

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. Researchers 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. He 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 Kenya, researchers studied whether information or price subsidies influenced demand for a simple health product which could be effective in preventing soil-transmitted helminths (STHs). While providing liquidity and targeting women can increase demand for preventative health products, price has the greatest impact on people's decision to purchase.

Researchers evaluated the impact of informing middle school teachers in Italy about their implicit stereotypes towards immigrant students on end-of-year grading. Both math and literature teachers eligible to receive feedback before the end-of-the-year grading gave higher grades to immigrant students.

In Uganda, researchers evaluated the effect of standardized business skills training on business performance as compared to more personalized mentoring services.

Researchers are working with a large bank in the Philippines, using random assignment to offer loans to SME applicants who fall just below the threshold to be automatically approved for a loan. Comparing firms that received the loans to a similar group that did not will allow for a better understanding of the impact of loans on firm performance and growth as well as any additional effects on firms in the same market or in the loan recipient’s supply chain.

Small and medium enterprises (SMEs) are thought to be important drivers of growth in developing economies, but entrepreneurs in these countries face many barriers, including poor access to training, finance, and business networks. In Colombia, Fundación Bavaria’s “Destapa Futuro” (Open the Future) program identifies promising enterprises and provides them with a suite of financial, technical, business, and training resources.

Researchers analyzed the effects of a small conditional cash transfer for education in Honduras on school enrollment and child labor.
