Identifying high-potential microentrepreneurs in low-income countries remains a challenge due to lack of verifiable information. Researchers conducted a randomized evaluation to test the value of community knowledge in identifying high-potential microentrepreneurs.

By running a Facebook public health campaign, researchers found that social media messaging from doctors and nurses reduced holiday travel and subsequent Covid-19 infection rates. This suggests that social media campaigns may be an impactful and cost-effective way to slow the spread of Covid-19 and enact behavior change.

Researchers conducted a randomized evaluation to gauge whether a short-term reading tutoring program could improve a range of student educational outcomes in the short- and medium-term (up to eight years after the program). They found that the program increased language test scores in the short term and improved several outcomes in the medium term, including reducing students’ probability of dropout, increasing their probability of graduating on time from primary and secondary school, and improving attendance, grades and test scores.

Researchers evaluated whether providing low-stakes diagnostic tests and feedback to teachers led to improved student learning outcomes in India. They found that teachers in intervention schools exerted more effort when observed in the classroom but students in these schools performed no better on independently-administered tests than students in schools that did not receive the program.

Researchers evaluated the impact of access to a package of free dental services on employment levels for urban residents of Santiago, Chile. Results found that participants with access to these services had better dental health, and that self-esteem and short-term employment increased among women, particularly those who had previously been missing front teeth or with lower levels of self-esteem.

Researchers evaluated whether an alternative teacher incentive scheme, providing rewards based on the performance of all students, could help reduce dropout and improve student math learning. Introducing the pay-for-percentile incentive scheme reduced overall student dropout rates. However, these reductions were driven almost entirely by students at intervention schools with math textbooks. Among schools with math books, the incentive scheme also improved the math achievement for higher performing students.

Researchers are measuring the impact of a quiz-style information strategy on people’s learning and adherence to Covid-19 health protocols. This study is part of a three-country research program in Ghana, the US, and Zambia aiming to find evidence on the best strategies to communicate health measures.

This study is part of a three-country research program in Zambia, Ghana, and the US aiming to find evidence on the most effective strategies to communicate health measures.

Much economic activity in low-income countries takes place through cooperative or collective organizations. Researchers in the Indian state of Karnataka conducted a randomized evaluation to study whether collective incentive payments to village cooperatives of dairy farmers could increase milk quality by reducing microbial contamination. Incentive payments increased cleanliness and point to the importance of leadership and social networks in cooperative production. However, a third of cooperative managers declined payments when they had to publicly disclose them.

Researchers conducted three randomized evaluations to measure the degree of competition among wholesale maize traders, understand the implications for social welfare, and test whether new traders could make a market more competitive. Researchers found that traders did not pass through much of a randomly administered cost reduction by lowering prices to consumers and, instead, colluded with other traders to maximize their profits.

Researchers partnered with a large payday lender in Indiana to conduct an evaluation to better understand consumers’ decision-making. The results suggest that average borrowers can anticipate their probability of taking loans in the future. However, people focus too much on the present when making decisions about payday loans, a behavior that they would like to change.

Responsive governments have the ability to make laws and decisions that reflect their constituents’ preferences. However, legislators may lack necessary information about constituents’ opinions and may therefore be unable to meet their demands. Researchers measured whether providing targeted information about citizens’ and firms’ preferences to members of the Vietnamese National Assembly (VNA) increased legislators’ responsiveness. VNA delegates who received information about their citizens’ preferences were more prepared and likely to speak in debates ; however, delegates did not appear to be responsive to information about local firms’ preferences. In addition, delegates grew more responsive as other delegates received the same information.

Using data from a previous randomized evaluation in rural India that tested the effect of asset transfers to low-income households on overall consumption, researchers analyzed whether an increase in household wealth led to changes in energy use. While households consumed significantly more energy after the asset transfer, they did not reduce their use of dirty fuels.
