Can cash crank up math test performance?


This study investigates whether incentives can improve the outcome of a test where subjects have to perform additions of two (easy) and four (difficult) numbers within a fixed time. Participants are randomly assigned to a treatment with monetary payment for each correct answer or no payment (hypothetical). The experiment is conducted in Ivory Coast, Czech Republic, Spain, Greece, and the Philippines. Overall, no impact of payments on performance (outcome) is observed, but there is a small effect on motivation (attempts)
