Researchers estimated the impact of a microcredit program, which was randomly rolled out in rural areas of Morocco. Thirteen percent of the households in treatment villages took a loan, and none in comparison villages did. Among households identified as more likely to borrow, microcredit access led to a significant rise in investment in assets used for self-employment activities, and an increase in profit, but also to a reduction in income from casual labor. Overall, there was no gain in income or consumption.

Researchers evaluate whether single women exhibit these tendencies in an elite US MBA program by testing whether students reported different ambitions privately and publicly, or if their responses varied when the audience was largely male. Researchers found that when they expected their answers to be shared, single women reported wanting US$18,000 less in annual compensation, jobs with less frequent travel, and work with fewer hours per week than when they thought their answers would be private.

In Kazakhstan, researchers tested whether offering youth community service grants and training impacted their level of community engagement, pro-social behavior, life skills, and labor market outcomes. Engaging youth in civic service and/or training had little to no effect on these outcomes one-year post-program, with some evidence of negative training effects on labor market outcomes.

Researchers conducted long-term follow-ups a mass school-based deworming program in western Kenya, which had substantially improved health and school participation of treated children, as well as of untreated children in treatment schools and children in neighboring schools in the short-term. Approximately ten years after treatment, researchers found that the program increased women’s educational attainment and men’s labor supply, with accompanying shifts in occupation choice. Twenty years after treatment, earnings, spending, and time spent working outside of agriculture had improved.

Researchers evaluated a mass school-based deworming program in Western Kenya, and found that deworming substantially improved health and school participation of treated children, as well as of untreated children in both treatment schools and neighboring schools. The program reduced school absenteeism by more than one-quarter, and was far cheaper than alternative ways of boosting school participation.
