Researchers partnered with the Egyptian Center for Women’s Rights to evaluate the effect of educational social media and TV campaigns on women’s attitudes and behaviors around responding to GBV and IPV. The social media campaign increased women’s knowledge and use of resources, but had no impact on their underlying attitudes towards gender equality or gender-based violence.

Researchers conducted a randomized evaluation to test whether exposing people to a documentary featuring potential role models impacted parents’ educational aspirations for their children or their actual investments in education, and if these impacts varied by gender. Exposing families to the documentary increased parental aspirations for educational attainment as well as investments in education, but it did not close the gender gap for either.

In Ghana, researchers worked with a bank that provides services to low-income customers with limited access to mainstream banking to evaluate the impact of sending pre-recorded informational voice calls and text messages on the adoption of mobile banking. Clients that received messages encouraging mobile banking were more likely to use mobile banking services and repay loans on time, while clients that received messages encouraging savings only had no measurable change in behavior.

A large charitable organization in the United States conducted a series of direct mail appeals for donations using different identity primes in 2009-2010. Researchers found that priming a potential donor’s identity as either a previous donor to charity or as a member of their local community generated more donations.

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 Uganda, researchers introduced a mentoring program to evaluate the impact of interactions between young, successful vocational training graduates and current vocational training students on their employment status and earnings. Students who received mentoring were more likely to be working three months after graduating, and had higher earnings a year after graduating.

Researchers are conducting a randomized evaluations to test the impact of different types of public health messaging on the practice of social distancing.

Technology adoption often requires investments over time. As farmers realize new information about the costs and benefits of investments, they may abandon the newly adopted technology shortly after. Researchers partnered with the non-governmental organization Shared Value Africa and Dunavant Cotton Ltd to investigate the effects of subsidies and follow-through rewards on the adoption of an agroforestry tree species.

Can facilitating relationships between small- and medium-sized businesses help them grow? In Jiangxi Province, China, researchers conducted a randomized evaluation to study the impact of business relationships on firm performance. Monthly meetings among firms increased sales, profits, and other business outcomes, mainly by facilitating learning and partnership development.

Using a technology-based math curriculum, researchers evaluated the impact of different incentive types—rewarding continuous effort in the classroom versus rewarding test performance—on student learning. Results indicate that effort-based incentives can be a more effective and cost-effective way of improving learning than incentives focused on test scores.

Researchers evaluated a nationwide debate initiative in Liberia designed to solicit and rebroadcast policy promises from legislative candidates. Results indicated that when leading candidates participated in debates, citizens were more engaged and informed.

Firms in low- and middle-income countries tend to hire mainly from referral networks, which may limit hiring. Online job portals can expand recruitment networks, but firms may be hesitant to hire unfamiliar candidates outside of their network. Researchers partnered with an online job portal in India to evaluate the impact of promotional advertising for job postings, candidate identity verification, or both services on hiring by firms. Only the combination of advertising and verification led to firms hiring more, suggesting that it is important to not only give firms access to a larger candidate pool but also provide them with the opportunity and tools to screen candidates.

Researchers conducted a randomized evaluation to determine whether PLS programs encouraged opening and use of bank accounts in Mexico. The lottery incentive increased the number of bank accounts opened, and accounts opened because of the PLS program were just as likely to be used as accounts opened without these incentives up to five years later.

Researchers evaluated the effects of an information campaign on workers’ awareness of and participation in a program that subsidizes skills-building training in Germany. Results showed that the information campaign doubled workers’ awareness of the program on average, but had no effects on program take-up or on labor market outcomes one to two years later. However, the campaign was successful in encouraging participation in other non-subsidized training services among workers aged below 45 years old.

Researchers in Ghana evaluated the impact of community-led assessments on health insurance enrollment as well as healthcare and health insurance quality. The community engagement intervention improved the medical quality of healthcare, reduced community members’ chances of getting sick, and increased health insurance enrollment among previously uninsured people.
