Researchers conducted a randomized evaluation to test the impact of offering frequent HIV testing on rates of marriage and pregnancy. Offering high-frequency, opt-out HIV testing to young women and their partners changed beliefs of partner’s sexual safety, accelerated marriage, and increased the probability of pregnancy.

Researchers introduced text message reminders to evaluate their effect on Kenyan patients taking their antiretrovirals consistently and not skipping doses. Patients who received weekly text messages were more likely to take their medicine 90 percent of the time and were less likely to skip doses for more than 48 hours than their counterparts in the comparison group.

In Bangladesh, researchers conducted a randomized evaluation to test whether helping selected farmers set up demonstration plots could increase awareness in the community about a new rice variety by triggering information exchanges through new interactions. Demonstration plots comparing new versus traditional seed varieties improved farmers’ knowledge about the new rice variety. The new interactions induced by the demonstration plots were most effective for farmers who were least socially connected before the intervention was delivered.

Researchers are conducting an evaluation of the Government of Kenya’s G-United youth volunteer program to test the effect of randomly placing students in locations they prefer on the retention of volunteers in the program, their job performance, and their employment outcomes after the program.

Researchers conducted a randomized evaluation to test the impact of an all-expense-paid three-day leadership training workshop on incentivizing honest and competent youth to run for a village youth council.

Building on previous research, researchers in this study evaluated the impact of several targeted instruction programs on the learning outcomes of primary school students in Ghana’s public schools. Researchers found significant improvements in numeracy and literacy on average; of the four interventions, in-school and after-school remedial lessons delivered by Teacher Community Assistants had the largest impact on pupil achievement.

Researchers are partnering with Lahore Transport Company (LTC), the public vehicle operation regulator, to introduce routes for small vehicles, known as wagons, that feed into a bus rapid transit system and will reserve a portion of wagons for women only. Researchers will evaluate the impact of these investments in public transportation on employment outcomes as well as on women’s empowerment.

To better understand barriers to COVID-19 testing for underserved communities, researchers evaluated the impact of varying flyer messaging and survey incentive rates on survey responses. Researchers will use survey responses to identify the most important barriers to testing and potential community leaders to effectively disseminate vital public health information. This research is ongoing. Results forthcoming.

In Sierra Leone, researchers evaluated the effect of publicly-screened debates during the run-up to parliamentary elections. Debates impacted voters’ political knowledge and voting decisions, and also caused candidates to invest more in their constituencies, both during the campaign and one year later.

In collaboration with China’s National Environmental Inspection Program, researchers are evaluating the impact of reporting firms’ hourly emissions data to environmental inspectors on the likelihood of firms being inspected, local air pollution, local economic output, and health outcomes.

In partnership with International Child Support, researchers designed and evaluated an incentives program that provided salary bonuses to teachers in Kenya based on the performance of their school as a whole on annual district exams. While results show that the incentives program led to an increase in student test scores, researchers believe that this increase was due to improved test-taking strategies and "cramming," rather than an increase in overall knowledge. The program did not have an impact on test scores in the long-run.
