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.

A key challenge to achieving universal health coverage is that non-poor informal workers are difficult to enroll and retain in government health insurance programs. Researchers conducted a randomized evaluation to test the impact of various programs, including subsidies, registration assistance and information campaigns on the enrollment and retention of non-poor informal workers in Indonesia’s national health insurance program. Registration assistance and subsidies both increased household enrollment, but overall enrollment rates remained low.

Researchers randomly provided free fertilizer to women rice farmers in southern Mali to measure how farmers chose to use the fertilizer, what changes they made to their agricultural practices, and the profitability of these changes. The fertilizer grants led to increased fertilizer use, use of complementary inputs such as herbicides and hired labor, and yields, yet did not lead to substantial increase in profit.

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 worked with a large nationwide retailer in the United States to test whether sharing information, and providing subsidies and sales incentives had an effect on the demand for energy efficient water heaters. Results showed that information alone did not increase demand, and a $100 rebate or the combination of a $25 sales incentives and a $100 rebate significantly increased purchases of the water heaters. In this context, providing more information alone was not an effective way of increasing demand for energy efficient durable goods.

Vaccination programs are considered to be cost-effective strategies to reduce child mortality and morbidity, but in many low-income countries, coverage for routine vaccines remains low. This is due to a range of possible factors including low parent knowledge about the benefits of vaccination, inadequate vaccine supply, and poor supply chain management. In Mozambique, researchers are examining the effectiveness of a mobile application-based solution that uses mobile technology to overcome these challenges and improve vaccination coverage.

Researchers conducted two randomized evaluations to test 1) the impact of providing public spending information on voter attitudes and 2) the impact of cash transfers on parental preferences for education.

Researchers evaluated the impact of providing schools with an unconditional cash grant, a teacher incentive program, or both on student learning. The cash grant had no impact on student learning, while the teacher incentive program had mixed results. However, combining both programs together had an even greater impact on student learning compared to the sum of the effects from each individual component alone.

Informational campaigns and price subsidies are common ways to increase the use of health products in developing countries, but little is known about the effect of combining these tools. In Zambia, researchers investigated whether households’ demand for chlorine at varying subsidy levels was dependent on their knowledge of the product. They found that providing additional information about chlorine significantly increased the impact of price subsidies on demand for the product. However, in the absence of a subsidy, information provision had no significant effect on take-up.

Finding effective strategies to prevent violence and systematic harassment at school can improve student outcomes and wellbeing. Researchers evaluated the effectiveness of two programs aiming to reduce violence and harassment in primary and middle schools in France. Overall, neither program reduced violence or harassment. However, social mediation was effective when the mediator was experienced, and particularly so for students who initially faced higher levels of violence.

Researchers contacted registered voters in a New England town by telephone and asked a portion of these voters to predict whether or not they would vote. This allowed researchers to use a randomized evaluation to measure the impact of making a prediction about future voting behavior on actual voting behavior. The study found no significant effect of prediction-making on voter turnout.

Researchers studied the short- and long-run effects of these reports on electricity use and found that reports reduced energy consumption by about 2 percent across twelve utilities. The reports had the strongest effect in the short-run, but the program had enduring effects among households that were dropped from the program after two years.

In rural Mexico, researchers examined whether conditional cash transfers (CCTs) protect families against income shocks and promote investment in children's education.
