Those self-employed in microenterprises, who often report low profits and own few assets, account for fifty percent of the labor force in low-income countries. Researchers are conducting a randomized evaluation to test the effect of relieving constraints to microenterprise relocation on business income in Kampala, Uganda.

Researchers conducted a randomized evaluation in Colombia to assess the effects of emergency cash assistance on the well-being of households. Recipients of the UCT experienced improved financial health, food access, and psychological well-being. Colombia’s newly implemented mobile money system allowed for quick fund disbursement, but its effectiveness for vulnerable populations may have been weakened by nascent digital systems.

The researcher evaluated an opposition party’s door-to-door information campaign regarding increases in executive power or executive performance to determine the impact of widespread, non-state-authorized information on voter partisanship. In neighborhoods with majority opposition supporters, opposition increased; in neighborhoods with majority incumbent supporters, incumbent support increased.

Firms in low- and middle-income countries tend to hire mainly from referral networks, which may limit hiring. Online job portals can expand recruitment networks, but firms may be hesitant to hire unfamiliar candidates outside of their network. Researchers partnered with an online job portal in India to evaluate the impact of promotional advertising for job postings, candidate identity verification, or both services on hiring by firms. Only the combination of advertising and verification led to firms hiring more, suggesting that it is important to not only give firms access to a larger candidate pool but also provide them with the opportunity and tools to screen candidates.

Researchers evaluated the impact of an early childhood psychosocial stimulation program on child development outcomes in urban Odisha, India. They found that a home-visiting stimulation program led to greater development outcomes, particularly for boys, stunted children, and children with more educated mothers.

Researchers are partnering with Bridge International Academies to evaluate the impacts of interleaved problem sets, which allow for rapid performance feedback, on students’ learning outcomes in Nigeria.

Researchers are partnering with Bridge International Academies to evaluate the impact of an SMS-based information provision program on students’ learning outcomes in Kenya.

Researchers are conducting a randomized evaluation to test the impact of Chile’s economic stimulus package on the profits and survival of SMEs.

Researchers are conducting a randomized evaluation to test the impact of providing emergency job retention assistance to firms and workers on firm survival, worker-firm match survival, and labor market outcomes for firm owners and workers in Ghana’s informal sector. Research is ongoing; results are forthcoming.

Researchers conducted a randomized evaluation to test the impact of providing cash transfers to female entrepreneurs during the pandemic on their business outcomes and behavior. Firm profit, inventory spending, and food expenditures all increased for business owners that received the cash transfer. Additionally, the transfers caused a re-opening of previously closed businesses; however, PPE spending and precautionary management practices only increased among those who perceived Covid-19 as a major health risk.

The proliferation of mobile money across low- and middle-income countries has led to increased availability of mobile payment systems, which can potentially allow more flexible payment terms for customers. Subsidies increased the use of mechanized desludgings, while pre-paid deposit requirements had no impact on their use. The flexibility of being able to save in advance in an earmarked savings account through the save-at-will treatment increased take-up through the program, but did so at the expense of take-up outside the program.

Researchers evaluated the impact of practicing sustained cognitive activity on cognitive endurance and school performance in Lucknow, India. Students that spent additional time engaging in sustained cognitive effort received higher grades in all of their classes, improved their performance on tests, and appeared more attentive in the classroom.

Researchers are conducting a randomized evaluations to test the impact of different types of public health messaging on the practice of social distancing.

Although conflicting recommendations have been issued, recent evidence suggests that face masks may significantly reduce the spread of SARS-CoV-2. However, questions remain on how to effectively promote mask adoption. Research are conducting a randomized evaluation to evaluate the impact of free mask distribution combined with educational interventions on mask adoption in Kenya.

Low-income populations throughout the world often consume very few calories. At the time of this intervention in 2013, over 800 million people globally consumed fewer calories than were recommended to maintain a healthy weight. However, the impact of low caloric intake on economic productivity is not well researched. Researchers conducted a five-week randomized evaluation to test the impact of increased caloric intake on hours worked, earnings, and physical and cognitive ability for cycle-rickshaw drivers in Chennai, India. Drivers who consumed daily snacks worked and earned more and performed better on cognitive and physical tasks relative to drivers that received an equivalent value of cash. Supplemental survey data suggests that inaccurate beliefs and knowledge about the returns to calories and the caloric content of food may drive lower than recommended calorie consumption.
