Researchers introduced a convenient and hygienic sanitary product, reusable menstrual cups, to Nepalese girls in the seventh and eighth grades. Their evaluation addressed several questions: Is menstruation as large a barrier to education as many believe? Does switching to modern sanitary products increase attendance and school performance among girls?

This evaluation measured the determinants of insurance enrollment as well as the impacts of having insurance for informal sector workers by randomly varying the costs and convenience of signing up for a government health insurance program available to formal and informal sector workers in Nicaragua. Overall, take-up of the insurance and retention rates were low, and enrolling in the program did not provide an absolute cost savings for participants.

Approximately 85 percent of primary school age children in western Kenya are enrolled in school, but only about one-third of students finish primary school. This project was introduced in part to assist families of high-achieving girls to cover the cost of school fees, supplies, and activities.

Researchers evaluated the Malawi Diffusion and Ideational Change Project (MDICP), which sought to explore the demand for, and the impact of, learning one’s HIV status. While even very small incentives encouraged people to return for their HIV test results, rapid testing in the home had the greatest impact on program take-up. However, for most people, learning their HIV status did not substantially change long-term behavior.

Researchers evaluated the impact of the Balsakhi Program, a remedial tutoring education intervention implemented in schools in Vadodara and Mumbai, India, on student learning. The program significantly improved student test scores in both locations.

Researchers examined the level of racial discrimination in the United States labor market by randomly assigning identical résumés black-sounding or white-sounding names and observing the impact on requests for interviews from employers. Results found that résumés with white-sounding names received 50 percent more callbacks than those with black-sounding names, indicating that, all other things being equal, considerable racial discrimination exists in the American labor market.

This evaluation studied the influence of information and social networks on university employees' decisions to enroll in a voluntary Tax Deferred Account (TDA) retirement plan in the United States. The results indicated that an individual’s decision to participate in the TDA is affected by small changes in their environment (i.e. in their social network), and not only by receiving increased information.
