Researchers partnered with a local organization in Malawi to randomly vary the wages offered in a rural cash-for-work program, and evaluate the impact of wages on participants’ willingness to work. They found that nearly three-quarters of participants were willing to perform agricultural work even at very low wages and that wages had a limited impact on most participants’ decision to work.

In Mozambique, researchers evaluated if an information campaign using SMS, a hotline for electoral misconduct, and a free newspaper could affect voter turnout and other elections-related outcomes. All three programs increased voter turnout, while only distributing the newspaper strengthened demand for political accountability and reduced electoral problems.

Working in Botswana, researchers rapidly evaluated a phone-based remote learning program aimed at keeping children engaged with math during the Covid-19 pandemic. Students who received weekly SMS messages and phone calls to review math exercises increased their math skills after twelve weeks, while students who received only SMS messages did not.

Colombia used lotteries to distribute vouchers which partially covered the cost of private secondary school for students who maintained satisfactory academic progress. Three years after the lotteries, winners were about 10 percentage points more likely to have finished 8th grade, primarily because they were less likely to repeat grades, and scored 0.2 standard deviations higher on achievement tests. In the long-run, the PACES program increased secondary school completion rates by 15 to 20 percent.

Researchers conducted a randomized evaluation to measure the impact of an information program on parental school choice and long-term student achievement. They found that the intervention shifted household school choices of those who were not enrolled before the intervention toward establishments with higher average test scores, higher value add, higher prices, and schools that tend to be further from their homes.

Understanding the factors that influence voting behavior is a central policy issue. Often voting outcomes directly determine funding of critical public goods such as public education.

Self-control problems can lead people to fall short of their personal and professional goals, often resulting in lower than desired workplace productivity. Researchers, in partnership with an Indian data entry firm, conducted a randomized evaluation to test whether self-control problems existed in the workplace and strategies mitigate these problems.

Understanding workplace incentives and the motivations of workers is important for increasing workplace productivity and organizational efficiency. Many have suggested that employees are altruistic, willing to work harder when they believe that the amount of effort they exert in their job directly translates into value for their organization. Researchers conducted a randomized evaluation to measure the impact of different employee and employer payoffs on the productivity of workers hired to stuff envelopes for either one of several charities or for a grocery store. The results indicate that employees were more productive when compensated, in part, for the number of envelopes they completed. Furthermore, workers were more likely to exert effort when their work was of value to their employer but did not increase their effort when the value to their employer was greater. Workers did not change their effort in response to receiving a surprise increase or decrease in pay.
