The City of Chelsea implemented a cash transfer program called Chelsea Eats, which provided eligible households with up to US$400 per month for nine months. Researchers conducted a randomized evaluation on the impact of the unconditional cash transfer on health care utilization and a variety of health outcomes. Those who received the cash transfer had fewer emergency department visits, including those related to behavioral health or substance use, fewer admissions to the hospital from the emergency department, and more outpatient visits to subspecialists than those who did not receive the cash transfer.

In partnership with the Provincial Government of Kasaï-Central in the Democratic Republic of Congo, researchers conducted a randomized evaluation during the 2018 property tax collection campaign to test the impact of lower property tax rates and stronger tax enforcement on revenue collection. Reducing property tax rates from current levels increased government revenue due to higher tax compliance.

Credit-building loan products (CBLs) have begun to proliferate in the U.S. marketplace, but there is little evidence on the effects of these products on consumers and lenders. IPA and RAND worked with researchers to evaluate the impacts of a CBL offered at a credit union in Missouri, both alone and coupled with financial education. While on average CBLs did not affect credit scores, they increased the likelihood of having a credit score and improved credit scores for individuals who did not have loans at the beginning of the study

Many smallholder farmers in sub-Saharan Africa do not use basic agricultural technologies to improve crop quality. In the Senegal River Valley, researchers tested whether receiving advance information on a market reform—introducing quality labels for onions and selling by weight—would lead to changes in farmers’ production habits. Onion farmers who received information about the reform were more likely to adopt practices to improve quality, leading to substantial revenue gains. Despite these gains, the reforms were abandoned in the following season, largely due to opposition from traders.

A researcher evaluated the impact of empowerment training for female citizens and training for male council chairs on women's participation in neighborhood associations, known as rukun tetangga (RT) in Malang, East Java, Indonesia.

The researcher used a randomized evaluation in Papua New Guinea to study the impact of the Community Auxiliary Police (CAP), a program that devolves policing powers to carefully selected community members. Results suggest increased state presence may have widened the gap between men and women’s preferences for state versus customary authorities but did not reduce crime.

Researchers evaluated the impact of bank accounts that allowed mobile deposits on savings behavior in Sri Lanka. Few account holders used the service frequently, even when offered for free. Mobile-linked accounts increased savings deposits with the partner bank and formal banks more generally but had no impact on total savings.

Researchers partnered with the Indian NGO Pratham to evaluate whether different technologies and implementation methods can increase students’ English test scores. Overall, the interventions were effective at increasing students’ knowledge of English.

Researchers conducted a randomized evaluation to measure the demand for private tutoring services and estimate how pricing can influence enrollment in these services. Results suggest that higher prices reduced demand for private tutoring and also led to higher drop-out rates over time, with no impact of tutoring on test scores.

Researchers evaluated the impact of immediately following up an early childhood development intervention for one-to-three-year-old children with a second intervention for three-to-six-year-olds. The early and late interventions each increased IQ and school readiness for children, although there was not enough evidence to determine whether offering both programs was more effective than offering one.

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.

Researchers conducted a randomized evaluation to test the impact of reducing the psychological costs of job applications, such as the tendency to postpone applications because completing a task today seems more burdensome than tomorrow, on job application rates and interviews in Lahore, Pakistan. The intervention, which involved follow-up calls inviting job seekers to apply for jobs, increased the number of job applications and interviews. The benefits of applying to jobs were similar after the increase in applications, suggesting that psychological costs play an important role in job search behavior.

Researchers evaluated a voter information campaign and exploited the random assignment of reservations for women in village councils to measure the impact of information and reduced incumbent advantage on village council elections. Both interventions increased the number of candidates and drove the worst performers out of the race, though in the case of the voter campaign they had short-term costs in terms of officials’ performance post-election.

Researchers conducted a randomized evaluation to test whether supplementing SGs with additional funds impacts SG members' financial access and behavior. Capital infusions to Sgs increased members' access to loans and members received more money at the end of year payout, without increasing defaults and debt.

The researcher used a randomised evaluation in Kenya and Uganda to study the impact of varying access to information about prices in buying and selling markets, and encouraged informal traders to enter new markets and take advantage of price differences.
