Researchers partnered with the Côte d'Ivoire government to measure the short- and long-term impacts of a public works program, along with complementary trainings on basic entrepreneurship and job search skills. In the short term, the program led to a shift toward wage jobs (as opposed to self-employment), higher earnings and savings, and improved well-being. However, most of these effects dissipated in the long-run.

Researchers evaluated the impact impact of both general exposure to mass media and an intensive family planning campaign on contraception. Increasing exposure to general mass media reduced contraception use in this context. However, a high-quality family planning radio campaign offset the negative effect of general mass media and increased contraception use, lowered births and misperceptions about contraception, and increased reported welfare.

In three related evaluations in India, researchers introduced an early childhood reading and comprehension program (Shishuvachan) in different contexts—integrated into first-grade classes in Mumbai public schools, implemented in preschools that were specifically designed to implement this program, and integrated into established preschool classes—in order to measure its impact on early literacy rates. Results show that the Shishuvachan program was very effective in improving students' reading skills.

Researchers evaluated whether cash transfers and decision-making nudges could help low-income pregnant women in Nairobi, Kenya deliver where they wanted and in a high-quality facility. They found that cash transfers, conditioned on precommitment to a delivery facility, led to more effective birth planning and increased the likelihood that women delivered at higher-quality facilities.

Researchers evaluated whether offering individuals financial incentives to maintain their HIV-negative status could be an effective HIV prevention strategy in rural Malawi. The conditional cash transfer had no effect on HIV status or on self-reported sexual behavior. The receipt of the cash incentive actually increased the likelihood of risky sex among men but decreased risky sex among women.

In the United States, many people who are eligible for social and economic benefits do not claim those benefits. Researchers partnered with the U.S. Internal Revenue Service (IRS) to test the effectiveness of different messages to taxpayers designed to encourage them to claim certain tax benefits.
