Researchers conducted two randomized evaluations in Bangladesh to study the impact of a new irrigation method and different pricing schemes on water use and conservation. The new irrigation method reduced water consumption and costs for farmers who were already paying for water by the hour, or by volume.

In partnership with country governments and the World Bank, the research team has been evaluating how different productive packages impact the wellbeing and economic stability of safety net beneficiaries in Burkina Faso, Mauritania, Niger, and Senegal. In Niger, a multi-faceted economic inclusion program delivered to women beneficiaries of a national cash transfer program improved women’s consumption and food security, increased their off-farm business activities, and improved their psychosocial well-being.

To better understand the connection between BTB policies and racial discrimination in hiring, researchers tested the impact of applicant race and criminal history on hiring decisions both before and after BTB policies came into effect in New Jersey and New York City. The results confirmed that criminal records are a barrier to employment and supported the concern that BTB policies encourage racial discrimination.

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 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.
