    Abstract: Organizations often use financial incentives to boost employees’ commitment to work-relevant goals in an effort to increase persistence and goal achievement (e.g., to improve organizational efficiency or sales). We introduce and test a novel incentive scheme designed to enhance persistence by increasing commitment to the goal of maximizing earnings. Specifically, we test “streak incentives,” or rewards that offer people increasing payouts for completing multiple consecutive work tasks. Across six pre-registered studies (total N = 4,493), we show that, contrary to standard economic models suggesting people will complete more piece-rate work for larger rewards, people actually complete more work when compensated with streak incentives than with larger, stable incentives. We theorize that this occurs because, by encouraging consecutive task completion, streak incentives increase commitment to a goal of maximizing earnings, which in turn increases persistence. We also show that this effect is not driven by providing increasing rewards; rather, people’s goal commitment and motivation are boosted by the requirement that they complete work tasks consecutively to earn escalating payments. Taken together, our results suggest that designing incentives to encourage streaks of work is a low-cost way to increase goal commitment and therefore persistence in organizations and other contexts.
