Researchers evaluated the impact of randomly varied information about candidates’ political connections on voters' beliefs and self-expressed support in the context of a 2015 local election in Sargodha, a district in rural Pakistan. Providing information on candidates’ connectedness increased voters' expressed support for more well-connected politicians.

Researchers conducted a randomized evaluation to test the impact of the combination of an in-school learning program with an out-of-school learning program on primary school math and reading levels. The combination of the two programs led to a significant increase in children's test scores in both math and language.

Researchers partnered with the tax authority in Belgium to understand what types of messages drive people to comply with their taxes. Results show that simplified messages, as well as messages that highlighted the consequences of non-compliance, induced people to file and pay their taxes sooner. On the other hand, messages aimed at promoting social norms around filing and paying taxes on time, and the social value of public expenditure, had no effects and sometimes even reduced compliance.

Researchers are conducting a randomized evaluation to test the impact of providing a new technology--smart meters--on consumer payments and service quality. Research is ongoing; results are forthcoming.

In Turkey, researchers evaluated the impact of a new pedagogical approach aimed at cultivating primary school students’ curiosity, particularly in science, to improve learning outcomes. Students whose teachers adopted the approach displayed greater curiosity, ability to retain knowledge, and science test scores, with effects persisting into middle school years.

Researchers conducted a randomized evaluation to test the impact of employment on refugee psychosocial well-being in Bangladesh. The study found that employment generated significant psychosocial value beyond that from cash transfers alone.

In this randomized evaluation in Zimbabwe, researchers studied how social media messages targeting misinformation can affect people’s beliefs about and responses toward Covid-19. The study found that these messages increased participants’ knowledge of Covid-19 information by 7 percentage points and reduced potentially harmful behavior, or noncompliance with lockdown guidelines, by 30 percentage points.

Researchers evaluated the impact of a flexible microloan product on new clients' repayment behavior, business outcomes, and client satisfaction. The results showed that the flexible loan led to some shifts in investment behavior but had no average impact on revenue or profits and led to higher default.

Those self-employed in microenterprises, who often report low profits and own few assets, account for fifty percent of the labor force in low-income countries. Researchers are conducting a randomized evaluation to test the effect of relieving constraints to microenterprise relocation on business income in Kampala, Uganda.

Researchers conducted a randomized evaluation to test the impact of expected earnings on candidates’ perception of a community health worker position in Uganda, and on the resulting size and composition of the applicant pool. Fewer socially motivated participants applied when advertised wages were particularly high. Although higher wages increased the total number of applicants and workers hired, workers attracted by the potential for higher earnings also had lower performance and retention.

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.

In this randomized evaluation in Romania, researchers compared the roles of preferences and information in households’ decision-making, with regard to high school selection. Results suggest that households provided with information on school quality tend to choose schools that have a greater academic impact on their children. However, households’ preferences for other school attributes also factor into their decision-making, including peer quality, location, and, most importantly, curriculum.

In India, researchers are conducting a randomized evaluation to test the effects of providing men with correct information about other men’s views of women’s labor market participation.

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.
