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 business plan competition to test whether panel judges or questionnaires answered by firm owners could more accurately identify the fastest growing firms in Ghana. Both survey assessments and judging of business plans through panels selected firms with the potential for faster growth.

In this randomized evaluation in Romania, researchers compared the roles of preferences and information in households’ decision-making, with regard to high school selection. Results suggest that households provided with information on school quality tend to choose schools that have a greater academic impact on their children. However, households’ preferences for other school attributes also factor into their decision-making, including peer quality, location, and, most importantly, curriculum.
