In Uganda, researchers conducted a randomized evaluation to test the effectiveness of a program in which landowners were paid to not cut forest trees on their property. During the study period, landowners who were offered contracts to conserve forest cleared 4 percent of forested land, compared to 9 percent in villages where the program was not offered, delaying 3000 metric tons of carbon dioxide per village from being released into the atmosphere.

Researchers tested the influence of the (randomly chosen) rate at which clients were told contributions to their Individual Retirement Arrangements (IRAs) would be matched on the amount contributed to their retirement savings accounts. They found higher matching rates significantly increased IRA participation and contributions.

Working with a microfinance institution in Ecuador, researchers investigated whether providing timely reminders to save via text message can help people save more.

Researchers conducted a randomized evaluation with a bank in the Dominican Republic to compare the impact of two distinct programs: standard accounting training versus a simplified, rule-of-thumb training that taught basic financial heuristics.

To test the impact of information on teenagers’ sexual decisions, a “Relative Risk Information Campaign” was conducted in 71 schools to give students information about the distribution of HIV infection rates by age and gender groups and discuss the role of cross-generational sex in the spread of HIV. The information led to a significant reduction in unwanted teenage childbearing with older partners, suggesting a decrease in unprotected sex with older partners.

Researchers worked with Mercy Corps to evaluate the impact of a sports and life skills development program on psychosocial and labor outcomes of vulnerable young people. While the program had no effect on improved psychosocial well-being or resilience, it did lead to an increase in labor force participation.

Researchers are testing whether delivering cash through governmental institutions or through an existing MFI is more cost-effective and easier to scale-up.

In partnership with a mobile network operator launching a new phone-based savings account, researchers evaluated the role of defaults and financial incentives on savings decisions. Two months after the launch of the phone-based savings account, the company’s employees randomly assigned a default contribution rate of 5 percent were 40 percentage points more likely to contribute to the account than employees assigned a default contribution rate of 0 percent.

To better understand gender inequalities in academic achievement, choice of occupation, and labor market outcomes, researchers studied the effect of teachers’ beliefs about gender roles on student achievement in Istanbul, Turkey. Girls who were taught by teachers with traditional gender views had lower math and verbal test scores, which worsened with longer exposure to their teachers; boys did not experience these effects.

This study estimated the effect of financial incentives on teacher attendance on students' attendance and math and language levels. The incentives increased teacher attendance and teaching time, and student test scores rose as a result.

Researchers partnered with the Akshara Foundation in Bangalore, India to evaluate the impact of hiring trained librarians in primary schools on students’ academic achievement. Overall, the intervention had little effect on students' language, math, and science skills and had no impact on student attendance rates.

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 tested the effect of an inventory credit program that provided storage facilities and loans on palm oil farmers’ agricultural activities in Sierra Leone. Take-up and use of the storage and loans was low, and there was no impact on total storage or timing of sales.
