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 Tanzania, researchers examined whether making cash payments conditional on testing negative for sexually transmitted infections (STIs) can improve safe sex practices among young adults. They found that offering cash incentives of US$20 significantly reduced STI rates after one year, although smaller incentives of US$10 had no effect.

Many urban areas in developing countries lack basic services such as piped water, electricity, sewage lines, and paved roads. Researchers analyzed the effect of paving streets in residential areas in Mexico on the living standards of adjacent households. Street paving increased property values, allowing households to purchase more home appliances and vehicles and to invest in home improvements. A cost-benefit analysis suggests that the economic returns to paving streets outweighed the construction costs.

Trade credit, which is usually provided by up-stream suppliers to down-stream firms, can help small businesses to purchase non-perishable goods for resale and free up resources for other uses. However, provision of trade credit may be limited by high transaction costs, up-stream liquidity constraints, and concerns over repayment. In Kenya, researchers are evaluating the impact of a new method of extending trade credit facilitated by mobile banking and inventory management technologies on small business development.

Researchers assessed the impact of a recreational tutoring program on students’ academic achievements and interest for school work provided by the NGO Apfee. Researchers found that children identified as falling behind by their teachers in schools where the tutoring program was offered did not improve their reading or math skills, although they developed a taste for reading and academic subjects. These results hold two years after the implementation of the program.

Researchers evaluated the expansion of a rural financial services provider in Tamil Nadu, India in order to understand how access to financial services, information, and exposure to risk affect technology adoption and well-being among farming households.

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.

Researchers conducted a randomized evaluation to test 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.
