Centering on one native Amazonian society (Tsimane’) and partnering with a Bolivian non- profit, researchers evaluated the impact of providing Tsimane’ households with lockboxes on their savings activity, consumption, and well-being. Providing lockboxes increased household financial assets but had no impact on total household expenditure; receiving lockboxes also increased alcohol consumption and blood pressure.

In Uganda, researchers evaluated whether offering financial education or group savings accounts to church-based youth groups increased savings. One year after the intervention ended, they found that total savings and income had increased among youth who were offered financial education, group savings accounts, or both education and group accounts.

In Bolivia, researchers investigated whether alarm boxes, designed to both remind people to save and to keep their savings safe, could have an effect on savings rates among microfinance clients.

Researchers examined the effect of a series of informational messages on participation in a recycling program in Peru. The messages sought to elicit pressures such as social norms, peer comparison, conformity, authority, and the environmental or social benefits to increased participation. They found that none of the messages had any effect on recycling. A parallel intervention, the provision of free plastic recycling bins, proved to be much more effective.

In southern and eastern Ghana, researchers evaluated two youth financial literacy programs to test their impact on savings, labor, academic performance, and financial decision-making. One program integrated financial and social education, while the second only offered financial education. Both programs had a positive impact on savings at school, but no impact on overall savings. Some evidence suggests that the program without the social education component also led children to work more.

Researchers examined whether small incentives and short-term goals could encourage Colombian loan officers to stop procrastinating. Under the new incentive structure, loan officers spread their work more evenly throughout each month, and they met a much greater percentage of their monthly targets.

In Nicaragua, researchers examined the impact of interacting with motivated community leaders on aspirations, household investment, and long-term living standards. They found that social interactions with these motivated community leaders increased households’ investments in education, nutrition, and income-generating activities, and improved households’ attitudes towards the future.

In Nicaragua, researchers examined the impact of a national conditional cash transfer (CCT) program on early childhood health and development. They found that the program caused substantial and lasting improvements in child health and development outcomes. However, it seems that program components other than, or in addition to, the cash transfers appear to drive these effects.

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.

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.

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