Researchers conducted a randomized evaluation in the Indian state of Tamil Nadu on the impact of adding an additional education-focused worker in early childhood development centers on students’ learning and health outcomes. The program increased the time spent on pre-school education, boosting learning in math, reading, and executive function. It also allowed the main worker to devote more time to health and nutrition, reducing severe malnutrition and stunting.

n collaboration with China’s National Environmental Inspection Program, researchers are evaluating the impact of reporting firms’ hourly emissions data to environmental inspectors on the likelihood of firms being inspected, local air pollution, local economic output, and health outcomes.

Researchers partner with a rural development organization to evaluate financial incentives for voluntary groundwater conservation among smallholder farmers in Gujarat, India.

Researchers conducted a correspondence study assessing property managers’ responses to rental listing inquiries from prospective tenants with distinctively Black, Hispanic/Latinx, or white names in the United States. Property managers were significantly less likely to respond to messages from prospective Black or Hispanic/Latinx renters than white ones.

Researchers conducted three randomized evaluations to measure the degree of competition among wholesale maize traders, understand the implications for social welfare, and test whether new traders could make a market more competitive. Researchers found that traders did not pass through much of a randomly administered cost reduction by lowering prices to consumers and, instead, colluded with other traders to maximize their profits.

Researchers conducted a randomized evaluation to test the impact of a cash transfer program conditional on seasonal migration and an unconditional cash transfer (UCT) program on rural households’ decisions to migrate and migration season earnings in West-Timor, Indonesia. Relative to the UCT, the CCT was most effective at raising migration season earnings when the transfer size was just enough to cover migration expenses; however, when the transfer size exceeded migration travel costs, relatively lower-income households migrated for the purpose of collecting the transfer and overall program impact lessened.

Researchers partnered with a large payday lender in Indiana to conduct an evaluation to better understand consumers’ decision-making. The results suggest that average borrowers can anticipate their probability of taking loans in the future. However, people focus too much on the present when making decisions about payday loans, a behavior that they would like to change.

Researchers working in India conduct an adaptive randomized controlled trial to evaluate the impact of a SMS-based information campaign on the adoption of social distancing and handwashing in rural Bihar, India, six months into the COVID-19 pandemic.

Researchers introduced a randomized information intervention to see if providing information on how different allocation methods work would shift the preferences of beneficiaries of a Nepalese land allocation program. On average, the information intervention did not change preferences for how land should be allocated, and about half of participants still preferred allocation methods that were less likely to match them with their desired plot of land.

Researchers are working with small- and medium-sized enterprises in the leather goods and footwear manufacturing sector in Bangladesh to understand the role of information in the adoption of energy-efficient motors for stitching machines, as well as firms’ perception of and willingness to pay for the new technology. This study in ongoing and results are forthcoming.

Researchers conducted a randomized evaluation to measure the impact of sanitation and hand-washing promotion campaigns, alone and in combination, on household knowledge, behavior, and child health (diarrhea prevalence, stunting, wasting, and anemia). While the program improved hygiene and sanitation behavior, it had no impact on child health outcomes.

Researchers studied hiring discrimination among major employers in the United States by sending fictional resumes, with varying demographic information, to determine whether certain characteristics would lead to different follow-up contact rates. Employers were less likely to contact resumes with distinctively Black names than resumes with distinctively white names.

Researchers partnered with Innovations for Poverty Action and Bangladeshi policymakers to test various strategies to increase mask-wearing and assess the impact of community mask wearing on SARS-CoV-2 infection rates. They found that a four-part intervention tripled mask usage and increased physical distancing. Further, this increase in mask-wearing reduced symptomatic SARS-CoV-2 infections. When surgical masks were employed, 1 in 3 symptomatic infections were avoided for individuals 60+ years old—the age group that faces the highest risk of death following infection. This was the first large-scale randomized evaluation to demonstrate the effectiveness of masks in a real-world setting.

Researchers are conducting a randomized evaluation to test the impacts of group-based therapy with and without a one-time lump sum cash transfers on the mental health and employment outcomes of adolescent girls in Uganda.

Cognitive behavioral therapy (CBT) may be an effective mental health approach for people living in poverty, who are especially vulnerable to mental distress and face unique demands on their mental “bandwidth.” Researchers worked with Innovations for Poverty Action and the University of Ghana Medical School to design, implement, and conduct a randomized evaluation of the impacts of a group CBT curriculum on low-income individuals in rural Ghana.
