Working with the Ministry of Health and Sanitation in Sierra Leone, researchers evaluated the impact of incentivizing community health workers (CHWs), their supervisors, or both on health care provision. Sharing the incentive between CHWs and their supervisors resulted in more health care visits than providing the incentive just to one group or the other; only the shared incentive improved overall health care provision and outcomes.

Researchers tested the impact of a meritocratic promotion system and beliefs about pay progression on the productivity of Community Health Workers in Sierra Leone. A combination of meritocracy and the promise of a steep salary increase after promotion led workers to make more health care visits, while non-meritocratic promotions with higher pay progression demotivated workers, reducing their productivity.

Researchers conducted a randomized evaluation to test the impact of expected earnings on candidates’ perception of a community health worker position in Uganda, and on the resulting size and composition of the applicant pool. Fewer socially motivated participants applied when advertised wages were particularly high. Although higher wages increased the total number of applicants and workers hired, workers attracted by the potential for higher earnings also had lower performance and retention.

Researchers conducted a randomized evaluation to test both the impact of BRAC’s extension program on economic outcomes and the role of social incentives in shaping the delivery of the program to farmers. While they found that overall, farmers in villages that received the program had higher agricultural profits, the number and type of farmers who were targeted depended on the political alignment between the selected and non-selected delivery agents.

Researchers in rural Western Uganda tested whether a microfinance program can help women borrowers switch out of subsistence agriculture to other labor activities, such as entrepreneurship or small-scale trading. While microloans helped women switch into service-based jobs including small-scale trading, they had no impact on income, spending, savings, and overall wealth.
