Empirical studies of the principal-agent relationship find that extrinsic incentives work in many instances, linking rewards to performance increases effort, but that they can also backfire, reducing effort. Intrinsic motivation, the internal drive to work to master a skill or to improve one's...

We conduct a field experiment among 189 stores of a retail chain to study dynamic incentive effects of relative performance pay. Employees in the randomly selected treatment stores could win a bonus by outperforming three comparable stores from the control group over the course of four weeks....

How does effort respond to being graded and ranked? This paper examines the effects of non-financial incentives on test performance. We conduct a randomized field experiment on more than a thousand sixth graders in Swedish primary schools. Extrinsic non-financial incentives play an important...

This paper shows that the incentive effects of heterogeneity may be positive rather than negative in dynamic contests with multiple stages. In particular, the well-studied adverse effects of heterogeneity in static interactions are compensated by positive continuation-value and selection...

We derive a natural definition of responsibility in a formal model where employees care for their career prospects: A superior holds a subordinate responsible for a task, when she announces her beliefs that this subordinate contributes most to this task. We show, that those announced beliefs...

How does the tax system's complexity affect people's reaction to tax changes? To answer this question, we conduct a real-effort experiment in which subjects receive a piece rate and face a set of taxes. In one treatment the tax system is simple; in the other treatment it is highly complex. The...

An investor's choice between safe and risky assets has long been seen as a behavior toward risk: more risk-averse investors buy more of the safe asset. Applying this intuition to incentive pay contracts, we develop a model and an experiment that show, in a very general setting, that the choice...

Optimal team composition has been the focus of exhaustive analysis, academic and otherwise. Yet, much of this analysis has ignored possible dynamic effects: e.g., anticipating that team formation is based on prior performance will affect prior performance. We test this hypothesis in a lab...

A previous literature cautions that paying workers for performance might crowd out non-monetary motives to work hard. Empirical evidence from the field, however, has been based on between-subjects designs that are best suited for detecting crowding out due to low-powered incentives. High-powered...

We develop a new approach to quantify how patients respond to dynamic incentives in health insurance contracts with a deductible. Our approach exploits two sources of variation in a differences-in-regression-discontinuities design: deductible contracts reset at the beginning of the year, and...
