In Ghana, researchers worked with a bank that provides services to low-income customers with limited access to mainstream banking to evaluate the impact of sending pre-recorded informational voice calls and text messages on the adoption of mobile banking. Clients that received messages encouraging mobile banking were more likely to use mobile banking services and repay loans on time, while clients that received messages encouraging savings only had no measurable change in behavior.

Researchers are conducting a randomized evaluation to test the impact of a package of interventions with the aim of improving the quality of nurseries, enhancing nutrition, and empowering women to address poverty and promote early childhood development in Egypt.

Increasing levels of migration to the European Union have created significant challenges for governments to ensure migrants fully integrate and thrive in their host societies, but there is little rigorous evidence that evaluates current programs that promote social inclusion. Researchers are conducting a randomized evaluation to test the impact of a peer matching program that aims to increase information and improve social capital on migrants’ social attitudes, Swedish language skills, employment, education levels, and general feeling of belonging in Sweden.

Researchers conducted a randomized evaluation to test the impact of different types of labels to signal product quality on sellers’ ability to develop a reputation for consistently selling high-quality watermelons in China. The more expensive laser-cut label influenced sellers to provide higher quality watermelons than the sticker label. The use of the laser-cut label also led to higher sales profits, whereas the cheaper sticker label had no effect on profits.

Researchers conducted a randomized evaluation to study if Democratic climate advocates recruit others for climate advocacy and whether they reach out across party lines to increase bi-partisan support. While Democrats were motivated to mobilize others to email Congress on climate action, they were more likely to do so when they believed their efforts would influence like-minded, Democratic-leaning individuals.

Researchers conducted two randomized evaluations to test the impact of coaching teachers on integrating CAL in their elementary and middle school mathematics instruction in two large, diverse school districts in the United States. The intervention led to improved math performance in one evaluation and mixed results in the other, with test-score gains observed in classrooms with higher weekly CAL practice time.

Researchers conducted a randomized evaluation during the summer months of 2023 to test the impact of using contracts or contests to encourage energy savings and assess their cost-effectiveness. Researchers found that contests and contracts achieved similar levels of energy savings. However, contests were nearly twice as cost-effective compared to contracts.

Researchers used survey data to evaluate short-term outcomes for Boston’s SYEP participants in 2015. They found that the program significantly improved participants’ community engagement and social skills, many job readiness skills, and some academic aspirations.

Researchers are conducting a randomized evaluation to test the impact of emissions reductions-focused loan support to small and medium firms in Türkiye on reducing these firms’ greenhouse gas emissions and protecting firm growth.

In India, researchers conducted a randomized evaluation to test the impacts of providing long-range, seasonal weather forecasts on farmers’ investments on and off the farm, and their well-being. They found that farmers who had access to the forecast updated their beliefs about the upcoming agricultural season, tailored their investments accordingly, and this ultimately improved welfare.

Building off of previous quasi-experimental research, researchers conducted three randomized evaluations to test the impact of providing farmers with land tax subsidies, different ways of monitoring water access and the canal’s operations and maintenance, or farming minikits on farmers' use of irrigation on their cultivated land. Researchers found that none of the interventions affected farmers’ choices to adopt irrigation, suggesting that there were more binding factors that constrained farmers’ decision-making.
