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 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 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.

Researchers evaluated the impact of trainings for brick kiln owners and operators on air pollution, CO2 emissions, and kiln profitability.

Researchers conducted a randomized evaluation to investigate whether an expanded and more thorough version of an orientation program in the Philippines improved socioeconomic outcomes and facilitated settlement for migrants upon moving to the United States. The research team found that though the program did not have many sizable impacts, migrants who received the new orientation program acquired fewer social network connections in the United States.

In this randomized evaluation, researchers partnered with Planned Parenthood of Michigan to give vouchers for contraception to evaluate the impact of contraceptive costs on method choice. Those who received the vouchers were more likely to buy contraceptives and buy more expensive methods than those who did not receive vouchers. They also chose longer-lasting and more effective methods

Researchers conducted a randomized evaluation testing the impact of monthly cash transfers of $1,000 to low-income individuals in Texas and Illinois on household expenditures, debts and assets, and financial health. The study found that receiving the cash transfer increased spending by $310 per month, primarily on expenses related to housing, food, and cars.

Researchers leveraged existing randomization to evaluate the impact of ERA programs during the pandemic in four urban areas in the United States on measures of housing stability, financial security, and mental health. Receipt of rental assistance increased rent payment in the short term and modestly improved self-reported mental health. However, it had limited impacts on housing stability and financial security.

Workers with criminal records face substantially lower chances of securing employment compared to similar workers without such records. Researchers evaluated the effectiveness of different approaches, including wage subsidies, crime and safety insurance, past performance reviews, criminal record history, and objective information on worker performance, on managers’ willingness to hire people with criminal records. The study found that policies which directly addressed hiring managers’ concerns about productivity and risk effectively increased demand for workers with criminal records.

Researchers are working with a large bank in the Philippines, using random assignment to offer loans to SME applicants who fall just below the threshold to be automatically approved for a loan. Comparing firms that received the loans to a similar group that did not will allow for a better understanding of the impact of loans on firm performance and growth as well as any additional effects on firms in the same market or in the loan recipient’s supply chain.

Researchers conducted a randomized evaluation to test the impact of leveraging social networks to disseminate information about two technologies, pit planting and “Chinese composting,” on farmers’ adoption of these methods. Providing performance-based incentives to peer farmers had the biggest effect on technology adoption.
