Researchers partnered with a tea company in Malawi to study the effects of a savings product that allowed workers to defer payment of a part of their wages. The deferred wages program was generally popular and increased savings; in the longer run, it helped workers improve their houses.

Researchers partnered with an employer in Addis Ababa to assess the impact of a small monetary incentive to apply for a job or a higher wage offer on the quality of applicants to a vacancy for a clerical position. Both of these changes increased the quality of applicants by similar amounts.

Researchers tested whether a monitoring system that recorded employees’ fingerprints at the beginning and end of each day could improve staff attendance and patient health in primary health centers in Karnataka. The monitoring system increased attendance among medical staff, but not doctors, and absence penalties were not widely enforced. Though imperfectly implemented, the system led to a large increase in baby birth weight.

Researchers evaluated the impact of a residential energy efficiency program on energy savings and carbon emissions in the United States. They found that energy savings equaled only about half of the upfront cost of the program, which were far less than projected.

In Uganda, researchers examined the impact of a combination of life skills and vocational training on adolescent girls’ engagement in income-generating activities, control over their bodies, and aspirations. The bundled provision of hard vocational and soft life skills training led to substantial advances in economic empowerment and control over the body for adolescent girls, which persisted for four years.

In Lusaka, Zambia, researchers compared the effect of financial and non-financial reward schemes on sales of female condoms. They found that non-financial incentives were more effective than financial rewards at motivating hair stylists to sell female condoms to their customers.

Researchers in Kenya collaborated with the NGO International Child Support to measure the returns to different types of fertilizer among local farmers. While results show that all interventions led to increases in yield, rate-of-return calculations indicate that not all were profitable for the average farmer.

In Vadodora, India, researchers studied the impact of supplementing classroom instruction with computer-assisted learning (CAL) in primary schools. CAL significantly improved student’s math scores, but was less cost-effective than the remedial tutor-based program, Balsakhi.

Researchers evaluated the effects of a program designed to improve parental knowledge about students’ opportunities at the end of middle school on schooling decisions and dropout behavior. The program helped parents and their children make more realistic educational choices, reducing grade repetition and high-school dropouts.

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.

In Bangladesh, researchers evaluated the impact of different selling schemes on demand for water testing, and the impact of test results on switching to a safer well. Although group test sales and well safety placards increased substantially the likelihood that households switched to a possibly safer well, demand for testing was very low.

Researchers used a randomized evaluation to measure the impact of introducing credit scores on lending to small enterprises in Colombia. The adoption of credit scores increased productivity in the loan approval process and improved credit allocation.

Researchers conducted a randomized evaluation in Mali to study the role of giving information to different people within a network in the spread of that information. People who were social and more closely connected to those who were trained had more information. Female farmers were less likely to receive information, indicating that disseminating information through social networks may reinforce existing gender inequalities.

Researchers partnered with a Protestant church district in metropolitan Bavaria, Germany, to conduct a field experiment to reveal taxpayers’ motivations to comply with a local church tax. Researchers found that simplifying the tax notification, highlighting the possibility of tax enforcement, and offering rewards and recognition for timely payment affected taxpayers’ compliance behavior.

In Uganda, researchers studied the demand for rainwater storage devices, the effectiveness of various marketing strategies in promoting them, and their impact on indicators such as school attendance and women’s participation in the labor market.
