Researchers worked with the state government to evaluate the impact of three programs to build demand for vaccination: local immunization ambassadors, small, non-financial incentives, and tailored SMS reminders. The most effective policy option increased measles vaccination by approximately 55 percent by combining local immunization ambassadors selected by the community, incentives that increased in amount across the immunization schedule, and SMS reminders to caregivers about the next scheduled vaccine.

Working with the Rwandan Education Board, Educate!, and Akazi Kanoze Access, researchers are examining the impact of a program that trains teachers in Rwanda’s revised secondary school entrepreneurship curriculum on student academic, economic, and labor market outcomes.

Researchers are conducting an evaluation that randomized the provision of information in a survey to improve the likelihood that citizens paid their municipal property taxes and understood the role that unequal tax burdens played in determining the likelihood of people paying their full tax burden in Manaus, Brazil.

In Senegal, researchers are testing a new contract arrangement between farmers and cooperatives that includes credit, training, and a price premium for certified low-aflatoxin groundnuts on farmers’ decisions to adopt Aflasafe, aflatoxin levels, and output 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.

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.

Uninformed elected leaders or voters can negatively affect political accountability, such as decision-making on what and how public services are delivered to citizens. The researcher partnered with the Pakistan Muslim League-Nawaz party in Lahore to evaluate the demand and responsiveness of local politicians to information about their citizens’ preferences.

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.

Researchers are conducting a randomized evaluation of a subsidized housing assistance program for refugees in Jordan to assess its impact on their economic outcomes, psychological well-being, long-term migration decisions, and social integration into their host community.

Young job seekers in many countries face higher rates of unemployment, underemployment, and unstable employment than older groups, caused in part by information barriers. Researchers conducted an evaluation to test the impact of LinkedIn training on labor market outcomes for young, low-income job seekers in South Africa. Providing LinkedIn training increased end-of-program employment rates by 10 percent (7 percentage points), with effects persisting for twelve months.

In Bangladesh, researchers partnered with BRAC to evaluate the impact of repayment flexibility in loan contracts for microentrepreneurs. Repayment flexibility benefited traditional microfinance borrowers primarily through the provision of insurance, enabling riskier investments at lower default rates.

In partnership with the Latvian tax authority, researchers tested several types of emails to investigate the effect of behaviorally-informed messages on tax compliance. Messages that aimed to deter bad behavior by highlighting taxpayers’ moral obligations towards action increased on-time tax declaration submissions. In contrast, messages meant to induce social pressure did not increase on-time compliance, though they increased overall submission rates (i.e., the submission of on-time as well as late declarations).

In partnership with Bridges to Prosperity, the researchers are conducting a randomized evaluation across 23 districts in Rwanda to determine the impact of building footbridges on wages and agricultural technology adoption and production.
