Voters in Benin had a preference for clientelist political platforms, but certain subsets of voters such as women, consumers of mass media, and members of social organizations were less receptive to clientelism.

Researchers conducted a randomized evaluation to test how informal insurance within Indian sub-castes affected the demand for formal rainfall insurance, and subsequent risk-taking among households employed in agriculture. Informal insurance both increased and decreased the demand for formal rainfall insurance, depending on the extent to which informal and formal insurance covered individual losses.

Researchers conducted an evaluation to test the impact of an information campaign about fertilizer quality on farmers’ beliefs and their purchase and use of fertilizer. The information campaign led farmers to change their beliefs about the quality of fertilizer available in local markets and to buy more fertilizer.

To study the employment limitation of microenterprises, researchers offered microentrepreneurs capital to incentivize them to hire workers. Results showed that a wage subsidy did not lead to lasting increases in employment sales or profits.

In Mozambique, researchers conducted a randomized evaluation to test whether teaching about Covid-19 prevention and/or financial learning incentives enhanced participants’ knowledge related to Covid-19. They found that both interventions improved Covid-19 knowledge separately and, moreover, financial incentives complemented teaching to further improve knowledge about Covid-19.

Researchers conducted a business plan competition to test whether panel judges or questionnaires answered by firm owners could more accurately identify the fastest growing firms in Ghana. Both survey assessments and judging of business plans through panels selected firms with the potential for faster growth.

Can media campaigns increase voter turnout among those underrepresented in the electorate? Researchers randomly assigned areas covered by Native American radio programming to either receive or not receive targeted radio messaging encouraging listeners to vote in the 2008 and 2010 US elections. The results suggest positive, but statistically insignificant impacts of the radio messaging on voter turnout among Native Americans. Researchers identified radio targeting as a potentially cost-effective way to encourage ethnic minorities to vote.

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.

Researchers designed a free online tutoring program delivered by volunteer university students to test whether it could mitigate the effects of school closures during the COVID-19 outbreak. They found that the program had a positive outcome on students' learning outcomes, socio-emotional skills, and psychological well-being.

Researchers evaluated the impact of trainings for brick kiln owners and operators on air pollution, CO2 emissions, and kiln profitability.

Researchers conducted a randomized evaluation to test the impact and cost-effectiveness of fully online and blended STEM classes in Russia on student test scores. Students in online and blended courses achieved similar scores to students in traditional in-person courses at a lower cost.

In Liberia, researchers examined the short and long-term impacts of introducing alternative dispute resolution (ADR) trainings on the rate at which community members resolved property disputes and the incidence of violence related to those disputes. In the long-run, dispute resolutions became less violent in communities that received the ADR workshops, despite no reduction in the overall incidence of property disputes.

Researchers in France studied whether government-provided recruiting services would impact firms’ job postings and hiring by lowering recruiting costs. The recruiting services decreased firms’ hiring costs and increased firms’ job postings and hiring, including much sought-after permanent-contract hires.

Researchers conducted a randomized evaluation to measure the impact of peer referrals by current patients on the screening and identification of tuberculosis cases in India. Peer referrals and outreach by current patients to identified peers were more effective than health-worker led contact-tracing, while combining these interventions with financial rewards was a cost-effective strategy to improve tuberculosis screening and detection.

In partnership with Digital Green and Jeevika, researchers conducted a randomized evaluation in Bihar, India, to assess the impact of a video-based training on female farmers’ adoption of a climate-smart technique called System of Rice Intensification (SRI), and their yields and profits. Farmers increased their yields and estimated profits and the intervention demonstrated cost-effectiveness.
