Researchers evaluated two approaches to improving the quality of Colombian preschools. Providing additional resources to preschools for materials and new staff did not benefit children’s development and, unintentionally, led teachers to reduce their involvement in classroom activities. However, the addition of teacher training focused on teaching methods offset the negative effects on teacher behavior, improved the quality of teaching, and raised children’s cognition, language and school readiness.

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 evaluated a computer-based adaptive learning platform (Mindspark) for secondary school students in urban India to measure the impact of customized learning technology on student test scores. The program increased test scores across all groups of students and was cost-effective compared to traditional schooling models.

A lack of access to finance can impede the potential for growth among small firms. To meet this finance gap and to encourage high-growth entrepreneurship, governments and multilateral agencies throughout the developing world often directly fund small and medium enterprises. Governments, however, have little guidance when it comes to choosing the firms with growth potential, and making sure that limited funds are targeted where they will spur the most growth. In Mexico, researchers are evaluating the impact of providing government funding to small enterprises, and whether different types of selection panels are more effective at selecting firms with high growth potential.

This study examines how reminders to file taxes affect tax filing decisions among low-income individuals who did not appear on a filed tax return. The results of two randomized evaluations demonstrate that one-time reminders increase tax filing—both to claim tax refunds as well as to voluntarily pay balances owed to the IRS.

Researchers conducted a randomized evaluation to test the impact of a savings lockbox, or SMS reminders, on household saving, spending, and the ability to cope with negative shocks in rural Niger. Take-up and usage of the lockbox were high, and while the lockbox intervention did not affect overall saving or spending, it helped households cope with the negative effects of a health shock. Conversely, there were no additional effects of the SMS reminders.

Researchers randomly assigned employees at garment factories in Bangladesh to either continue collecting their wages in cash, receive direct deposit wage payments into a payroll account, or receive an account but continued to receive wage payments in cash. Exposure to payroll accounts led to increased account use, consumer learning, savings, and trust in mobile banking.

In partnership with the Ethiopian Development Research Institute (EDRI), researchers are providing report cards that document citizen satisfaction with a range of public services to various levels of government officials to measure the impact of information and accountability on public service provision.

Researchers are conducting a lab-in-the-field study to measure the impact of a community-driven development program in Bangladesh on participants’ preferences and values about fairness, equity, civic engagement, and participatory decision-making.
