Researchers evaluated the impact of practicing sustained cognitive activity on cognitive endurance and school performance in Lucknow, India. Students that spent additional time engaging in sustained cognitive effort received higher grades in all of their classes, improved their performance on tests, and appeared more attentive in the classroom.

Researchers compared the impact of two alternative programs, one that trained teachers how to teach the existing, abstinence-focused HIV prevention curriculum and another that subsidized education through the provision of free uniforms, on risky sexual behavior of adolescent students in upper primary school. Training teachers greatly increased teaching of the curriculum but had no effect on sexually transmitted infections (STIs) or teen pregnancy. Girls who received free school uniforms were less likely to get married, become pregnant, or drop out of school, but they were equally likely to contract an STI. The two programs combined did not reduce teen childbearing but led to a significant reduction in the risk of herpes among girls.

Researchers worked with the Government of Nicaragua to evaluate the long-term impact of time-limited CCTs on education, reproductive health, and labor market outcomes. Ten years later, people whose families were offered cash transfers when they were younger children had higher labor force participation and earnings on average than people whose families were offered cash transfers when they were older children.

Researchers evaluated a mass school-based deworming program in Western Kenya, and found that deworming substantially improved health and school participation of treated children, as well as of untreated children in both treatment schools and neighboring schools. The program reduced school absenteeism by more than one-quarter, and was far cheaper than alternative ways of boosting school participation.

Researchers evaluated the impact of auto-scheduling appointments with targeted messages and nudge reminders on primary care engagement within four months after delivery for postpartum individuals with diabetes, hypertension, mental illness, or obesity in the United States. Individuals who received this intervention were substantially more likely to have a primary care visit than those who did not, highlighting the potential of low-cost interventions to improve the transition of ongoing care needs after pregnancy to primary care clinicians.

In the United States, researchers evaluated the impact of the mandatory-participation bundled payment model for hospitals and explored which hospitals were incentivized to opt in to bundled payments after the model was later made voluntary. The mandatory-participation bundled payment program produced modest reductions in Medicare claims, but the voluntary program produced smaller declines in Medicare claims than if the mandatory program had continued.

Researchers combined subsidized weather index insurance with input loans for fertilizer and modern seed use for smallholder farmers in rural Ethiopia to investigate the impact of these products on demand for insurance and resulting shifts in agricultural technology use and crop yields. Results indicate that providing free insurance may not result in meaningful increases in investment in inputs like fertilizer.

Researchers conducted a randomized evaluation of the ways in which information dissemination within social networks affected farmers’ adoption of a weather insurance product in rural China. Results suggest that social networks had a significantly positive effect on insurance take-up, driven by the diffusion of knowledge about insurance. These effects were larger when people who were the first to receive financial education were more central to the social network.

Researchers conducted a randomized evaluation of the impact of the Oportunidades CCT program in Mexico on recipients’ investments decisions and long-run poverty levels. They found that the cash transfers promoted long-term increases in consumption through investment in productive activities, enabling beneficiary households to achieve higher living standards that can be sustained even after transitioning off the program.

Researchers conducted a randomized evaluation to test the impact of providing financial literacy education alongside various marketing strategies to small-scale farmers in Gujarat, India, on their demand for rainfall index insurance. Financial education had a significant effect on adoption of rainfall insurance, but was not a cost-effective way to raise demand.
