Researchers evaluated the impact of creating peer groups optimized to improve the academic achievement of lower-ability first-year students at the United States Air Force Academy. Placing lower-ability students in the optimized groups, which mixed them with a relatively large number of peers with high scores on the verbal portion of the SAT, caused the lower-ability students to perform worse, and actually led them to interact more with other lower-ability students.

Researchers used a randomized evaluation to measure the impact of a government program that gave groups of young people US$400 per person in return for a proposal to start a skilled trade. Recipients invested the cash and significantly increased their incomes for several years. However, nine years after the grants, non-recipients eventually caught up to grant recipients in terms of income and employment, suggesting that in this instance, grants acted more like a kick start than a lift out of poverty.

In Liberia, researchers examined the short and long-term impacts of introducing alternative dispute resolution (ADR) trainings on the rate at which community members resolved property disputes and the incidence of violence related to those disputes. In the long-run, dispute resolutions became less violent in communities that received the ADR workshops, despite no reduction in the overall incidence of property disputes.

In Liberia, researchers tested the effect of an intensive agricultural training program that also provided agricultural supplies and psychosocial counseling on employment activities, income, and socio-political integration. Fourteen months after the program, participants spent more time working in agriculture and less on illicit activities, and their income rose as a result.

Researchers partnered with five job centers to test whether health counseling targeted at youth increased insurance coverage and health care use, leading to better health and employment outcomes. Encouraging youth to meet with a social worker and with a physician increased enrollment in the public universal health insurance, but did not significantly affect youth’s understanding of their rights and of the insurance reimbursement procedures. The program almost doubled the number of youth that consulted a psychologist and increased the time spent participating in vocational training programs.

Researchers evaluated the impact of mailings that informed people with a record of felony conviction of their eligibility to vote on political participation. The mailing increased political participation, particularly among individuals that were active voters prior to incarceration.

Researchers present results from six randomized control trials of an integrated approach to improve livelihoods among the very poor. The impact on the poor households lasted at least a year after all implementation ended.

Kenya, East Africa's largest economy, is struggling with an ageing energy infrastructure and low connectivity to the power grid. William Jack and affiliate Tavneet Suri (MIT) study the impact of off-grid solar power on small retailers in Nairobi.

In India, researchers conducted a randomized evaluation to test how the provision of rainfall index insurance affected farmer production decisions, focusing on the decision to grow cash crops. They found that providing insurance led farmers to shift production towards higher-risk, higher-return cash crops.

Researchers evaluated the effect of randomly offering varied wages to bean-sorting workers in rural Malawi. While offering higher wages caused workers to increase their productivity, it did not attract more productive workers.

Researchers conducted a randomized evaluation to test the impact of offering interest-paying mobile money saving accounts to farmers, and in some cases farmers’ friends, on their financial behavior such as agricultural investment. Providing farmers access to interest-bearing mobile savings accounts increased both the amount of money they saved using these accounts and the likelihood they invested in fertilizer, while providing farmer’s closest farming friends the same incentivized mobile money accounts did not increase savings.
