Researchers randomly evaluated whether well-timed access to credit would allow maize farmers in Kenya to make better use of storage and sell their output at higher prices. The loan offers allowed farmers to store more maize and earn higher revenues, with larger revenue impacts for farmers granted loans immediately following harvest and in areas where a smaller share of farmers was offered loans.

Researchers evaluated the impact of financial incentives, public health video messages, and access to a vaccine scheduling link on Covid-19 vaccination intentions and vaccine take-up in the United States. None of the interventions led to increases in vaccine take-up after thirty days. In a subsequent study, researchers found that personal reminder messages led to increases in booster vaccination rates while monetary incentives had no additional impact.

In Mali, researchers conducted a randomized evaluation to test how the design and timing of a physical market for inputs (village input fairs) with varying levels of credit access affected farmers’ investment decisions. They found that farmers with access to credit from VIFs organized after harvest increased their demand for inputs while farmers offered VIFs at planting without access to credit did not.

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 are evaluating the impact of temporary supplemental math teachers on girls’ numeracy skills, professional aspirations, and early career labor market outcomes.

Researchers conducted a randomized evaluation to test whether organizing short learning sessions for villagers about early adopters’ use of a flood-tolerant rice seed variety, Swarna-Sub1, impacted other farmers’ adoption of it. These “farmer field days” were a cost-effective strategy to improve farmers’ learning about Swarna-Sub1 and increased their take-up of Swarna-Sub1 in the next planting season by 40 percent.

Researchers evaluated whether participating in the law-making process influenced firms’ compliance with regulations in Vietnam. Firms that participated in the drafting of new regulation had more positive views of the government’s regulatory authority, were more likely to allow auditors to examine facilities, and ultimately improved compliance with factory floor regulations.

Researchers evaluated an accountability workshop program, which educated citizens on the distribution of extractive industry tax revenues and the formal means of local political participation. The program had mixed results on local government quality, increasing the likelihood of initiating recall against poor-performing mayors but also increasing civil unrest. The workshops also reduced involvement in participatory budgeting, as well as reducing mayors’ discretionary spending efforts.

Researchers are evaluating the impact of providing information on national rank and scholarships can reduce dropout among high-performing students.

Researchers are using a randomized evaluation in Mexico to study the incentives media stations face when choosing to provide voters with indicators of their incumbent party’s performance in office.

In partnership with the Ethiopian Development Research Institute (EDRI), researchers are providing report cards that document citizen satisfaction with a range of public services to various levels of government officials to measure the impact of information and accountability on public service provision.

In the Philippines, researchers conducted a randomized evaluation to measure the impact of an evangelical Protestant religious values and theology education program on individuals' economic and subjective wellbeing.

Researchers partnered with bKash, one of the leading mobile money providers in Bangladesh, to evaluate the impact of targeted training programs on mobile banking uptake among migrant households. Training increased migrants’ and their families’ adoption of mobile banking, with women adopting the technology at similar rates to men, shrinking the gender gap.

Researchers are conducting a randomized evaluation to test the impact of text message reminders of key recertification processes and deadlines as well as access to paperwork assistance on enrollment in the SNAP program.

During the 2016 Ugandan elections, researchers conducted a randomized evaluation of an anti-vote-buying campaign to study voter behavior and electoral outcomes. Overall, the campaign did not reduce the extent of vote buying, but it had substantial effects on electoral outcomes.
