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 conducted a randomized evaluation in Ethiopia, Tanzania, and Zambia to measure whether generating social connections between manufacturing firm managers could lead to the diffusion and adoption of best business practices. These social interactions led to the spread of best practices related to business formalization, but did not increase the implementation of other practices that may boost business productivity.

Researchers are evaluating the impact of improved microcredit loan design on its take-up, as well as the welfare and business conditions of borrowers.

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 the City of Medellín, researchers randomly introduced a program that intensified government outreach to gang-controlled neighborhoods. The study found no evidence that the city’s intervention reduced gang rule.

In Sri Lanka, researchers provided wage subsidies to randomly chosen microenterprises to determine if they would hire more workers, and whether the additional labor would benefit such firms. The study found that while firms increased employment during the subsidy period, there was no lasting impact of the subsidies on employment, profitability, or sales.

This study will examine whether a combination of positive and negative commitment devices can induce long-term smoking cessation in smokers from a low-to-moderate income background in Connecticut.

In partnership with the Government of Tamil Nadu, researchers evaluated the impact of incentivizing and monitoring walking on exercise and health. Incentives increased walking and improved health, as measured by risk factors for diabetes and by mental health.

Recent studies have found that summer youth employment programs appear to generate large declines in the rates of violent crime—a significant finding for urban policymakers seeking to create safer, more vibrant cities.

In Indonesia and Tanzania, researchers conducted a mixed methods randomized evaluation of a transparency and accountability program designed to improve maternal and newborn health (MNH) outcomes, known as the Transparency for Development (T4D) program. While the T4D program drew strong participation, it had no impact on the use or content of MNH services, perceptions of civic efficacy, or participation among recent mothers in communities offered the program.

In partnership with a local dairy cooperative, researchers utilized a combination of evaluations and surveys to measure dairy farmers’ responses to various price and timing incentives. They found that farmers willingly declined daily payments at higher milk prices in favor of monthly payments at lower prices, a practice that allowed them to save and acted as a commitment device to meet their saving goals.

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.

To test whether TaRL can be implemented at-scale in government schools, researchers partnered with Pratham and the Government of Uttar Pradesh to evaluate the impact of high-intensity learning camps during school hours. The model proved highly effective, bringing about large improvements in student’s language and math learning levels.

Researchers partnered with a large sugar cane company to see if delaying the premium payment until after the harvest would increase farmers’ demand for insurance. Researchers found that farmers were much more likely to purchase insurance when the payments were delayed until after the harvest.

Researchers conducted a randomized evaluation to test the impact of targeting cash transfers to women on household spending and women’s empowerment. Targeting the cash transfer to mothers increased household spending on food. Women offered the transfers also had stronger measures of empowerment through increasing women’s control of household resources.
