Researchers conducted a randomized evaluation in Uganda to test the impact of a mobile phone-based marketplace for agricultural commodities on local market prices, entry of traders, farmer revenue, and trader profits. Overall, the platform increased trade flows and decreased price variation across markets, especially among markets close to each other.

How important are the returns to education in determining schooling decisions? Do students have accurate information about these returns when they choose whether to continue schooling? In partnership with the Ministry of Education in the Dominican Republic, researchers are evaluating the impact of informational videos about the benefits of education on the decision of students to invest in additional schooling. Preliminary results suggest that exposure to the videos lead to a decrease in dropout for 8th grade students.

Researchers partnered with a large Indonesian Islamic bank to evaluate the impact of sending moral appeals in reminder text messages to late-paying credit card holders. Messages stating that non-repayment of debts by someone who is able to repay is an injustice increased the number of clients meeting minimum payments, proving more effective than substantial financial incentives for repayment.

Researchers worked with the state government to evaluate the impact of three programs to build demand for vaccination: local immunization ambassadors, small, non-financial incentives, and tailored SMS reminders. The most effective policy option increased measles vaccination by approximately 55 percent by combining local immunization ambassadors selected by the community, incentives that increased in amount across the immunization schedule, and SMS reminders to caregivers about the next scheduled vaccine.

Researchers in Kenya conducted multiple lab studies at the Busara Center for Behavioral Economics to explore the degree of ethnic bias in the local population and assess how bias may affect participants’ behavior. Contrary to existing assumptions about ethnic preferences in Kenya, researchers found no evidence of ethnic bias in decision-making related to sharing of economic benefits and political alignment.

Technology adoption often requires investments over time. As farmers realize new information about the costs and benefits of investments, they may abandon the newly adopted technology shortly after. Researchers partnered with the non-governmental organization Shared Value Africa and Dunavant Cotton Ltd to investigate the effects of subsidies and follow-through rewards on the adoption of an agroforestry tree species.

Researchers are using a randomized evaluation in Mexico to study the incentives media stations face when choosing to provide voters with indicators of their incumbent party’s performance in office.

Researchers introduced a price regulation on poultry vaccines in Tanzania to evaluate the impact of reducing service providers’ discretion over prices on the number of recipients served, prices charged, and the overall welfare of beneficiaries. The price-cap reduced the average price of vaccinations, thereby making the product more accessible for smaller-scale and lower-income farmers. However, without discretion to raise prices, providers reduced coverage to more remote areas. On net, introducing price-caps reduced welfare.

The researcher used a randomized evaluation in Papua New Guinea to study the impact of the Community Auxiliary Police (CAP), a program that devolves policing powers to carefully selected community members. Results suggest increased state presence may have widened the gap between men and women’s preferences for state versus customary authorities but did not reduce crime.
