Researchers partnered with a local bank to learn how customers chose between two account types—an account that had been offered for many years, which carried high monthly fees but no individual transaction costs, or a new type of account that charged for each withdrawal but did not impose monthly maintenance fees. Customers without an existing account recognized the advantages of the new type of account and overwhelmingly chose to open one, while many customers with the existing account type did not switch to the new one. However, of the existing customers, those who used their account more due to receiving a financial transfer in the past did switch to the new account type, suggesting that more experience using financial products can improve financial decision-making.

Researchers introduced a Voluntary HIV Counseling and Testing (VCT) program to young females in Malawi to determine whether the program affects risky sexual behavior and school performance. They found no overall effect of VCT on risk of sexually transmitted infections or achievement test scores. However, those who tested positive for HIV had increased rates of other sexually transmitted infections, and those who were surprised by negative HIV test results experienced a significant improvement in test scores.

In Malawi, researchers evaluated the impact of a vocational training program on youth's skills, economic outcomes, and well-being. While the training generally improved skills and well-being, it had more positive effects for men compared to women, and had no impact on labor market outcomes in the short run for either gender.

In this study, researchers introduced report cards with child and school test scores to evaluate the impact on public and private schools’ cost, performance, and enrollment. The program reduced private school fees, improved test scores, and increased primary school enrollment.

Researchers evaluated a 31-day read-a-thon where students were encouraged to read as many books as possible through daily reading activities in school, such as storytelling sessions, reading games, and posters that display each class’s progress. Overall, the results suggest that encouraging an increased use of age appropriate reading materials by students was a viable strategy for improving student’s reading skills.

Researchers conducted a randomized evaluation to test whether exposing people to a documentary featuring potential role models impacted parents’ educational aspirations for their children or their actual investments in education, and if these impacts varied by gender. Exposing families to the documentary increased parental aspirations for educational attainment as well as investments in education, but it did not close the gender gap for either.

Using a technology-based math curriculum, researchers evaluated the impact of different incentive types—rewarding continuous effort in the classroom versus rewarding test performance—on student learning. Results indicate that effort-based incentives can be a more effective and cost-effective way of improving learning than incentives focused on test scores.

In western Rwanda, researchers evaluated the impact of community health clubs on household take-up of healthy behaviors and on the health of children under 5 years of age. The program had minimal impact on household behaviors and no impact on caregiver-reported rates of diarrhea among children under five.

Researchers evaluate whether single women exhibit these tendencies in an elite US MBA program by testing whether students reported different ambitions privately and publicly, or if their responses varied when the audience was largely male. Researchers found that when they expected their answers to be shared, single women reported wanting US$18,000 less in annual compensation, jobs with less frequent travel, and work with fewer hours per week than when they thought their answers would be private.

Researchers are evaluating the impact of providing different types of information about the health risks of Covid-19 on individuals’ risky behavior among diabetic and hypertensive individuals in Tamil Nadu, India, with special attention to de-biasing over-optimism about personal health risk.

Researchers partnered with Opportunity International Savings and Loans Limited (OISL) to conduct a randomized evaluation to test the impact of high-frequency interactive voice response (IVR) calls on people’s use of mobile banking services and their financial behaviors in Ghana. People who received the IVR calls were more likely to use mobile banking and make on-time loan repayments, increasing their access to subsequent loans; however, they were not more likely to save.

In order to measure the level of competition among traders in Sierra Leone’s cocoa market, researchers conducted a randomized evaluation to test the impact of delivering subsidies to cocoa traders on prices that traders paid to cocoa farmers. While the bonus payments did not affect the prices paid to farmers, it did lead the traders to more frequently offer credit through advance payments to farmers. These results suggest that Sierra Leone’s agricultural trading sector was competitive, meaning that all traders offered similar prices to farmers.

If female managers are more likely to hire women, gender-balanced hiring committees may help promote parity in the long run. Using data from public examinations to enter the Spanish judiciary, researchers found that female candidates were less likely to succeed in the public examinations when evaluated by mixed-gender committees than by all-male ones, while male candidates fared better with mixed committees.

In India, researchers conducted a randomized evaluation to test how the provision of rainfall index insurance affected farmer production decisions, focusing on the decision to grow cash crops. They found that providing insurance led farmers to shift production towards higher-risk, higher-return cash crops.

Researchers partnered with the Government of Paraguay to measure the impact of a new monitoring technology—GPS-enabled cell phones—on the job performance of agricultural extension agents (AEAs). Overall, cell phones improved AEAs’ performance by increasing the share of farmers visited, and researchers found that supervisors possessed useful information regarding which AEA’s performance would improve the most from phone-based monitoring.
