By the time they reach primary school, disadvantaged children often lag behind their more advantaged peers in the skills and concepts of formal math. To address this issue, researchers examined the impact of math games, played in preschools and exercising early emerging, universal and intuitive numerical and spatial abilities, on children’s learning of school math in Delhi, India. They found that the games led to long-term increases in children’s intuitive math abilities. The games also bolstered children’s mastery of the spatial and numerical language used in the preschools, but they did not enhance children’s subsequent learning of primary school mathematics.

Researchers evaluated the effect of an unconditional cash transfer program targeting mostly men on intimate partner violence in a context where nearly forty percent of households are polygamous. Polygamous households receiving the transfer experienced less physical and emotional violence, while monogamous households experienced no change.

Researchers examined whether intra-household risk-sharing mechanisms such as financial transfers between spouses operate efficiently in Western and Nyanza Provinces of Kenya and found that intra-household insurance to protect against economic shocks was inefficient among daily income earners.

Researchers sought to test whether intensive job counseling with a private provider is an effective means of increasing employment rates, even for a population with such a low attachment to the labor market. Results suggested that job-counseling increased employment rates among counseled individuals, and somewhat reduced their dependence on welfare. However, take-up of the service was low, and the cost of the program exceeded the savings generated from lower welfare payments.

In Western Kenya, researchers evaluated the impact of two preventive approaches—community-based testing and free condom provision—on behavioral and biological outcomes. Neither community-based testing, free condoms, nor these interventions offered together reduced the prevalence of sexually transmitted infections or risky sexual behaviors among youth.

In India, researchers partnered with Bandhan Konnagar to evaluate the impact of a multi-faceted livelihoods program known as the Graduation approach, which aims to encourage occupational change among people living in extreme poverty. The Graduation approach had large and positive effects on economic well-being and health over the long term, even ten years after the productive asset transfer.

Researchers conducted a randomized evaluation to look at the effect of private connections in a setting where most households already had access to high-quality water through public taps. They found that households had a high willingness to pay for piped water, and while home water connection had no impact on waterborne illness, households' self-reported happiness improved substantially.

In Indonesia, researchers conducted a randomized evaluation with seaweed farmers to observe both the impact of participating in a program that determined optimal seaweed production methods and receiving summarized results of the program on the adoption of optimal farming inputs. They find that simply participating and observing outcomes in the program did not change key input choices in the production of seaweed. Instead, farmers changed their practices only after they were presented with summaries on results from the program.

Career counseling for young, college-educated job seekers in France helped them find work sooner, but this improvement came at the expense of jobs for those who did not receive counseling, and it did not translate into a long-term increase in employment rates.

Researchers examined the impact of doubling teacher salary on student and teacher performance in Indonesia. This intervention had some positive effects on teachers: they reported higher levels of satisfaction with their jobs and less financial stress and were less likely to have a second job. However, doubling teacher salary had no effect on teacher knowledge, student test scores, or self-reported teacher attendance.
