We study experimentally voluntary contributions to public goods when none, some, or all previous decisions are observable. When agents observe previous moves, they tend to condition their cooperation on observed cooperation. This leads to two effects of increased transparency: on the one hand,...

This paper investigates the optimal design of incentives when agents distort probabilities. We show that the type of probability distortion displayed by the agent and its degree determine whether an incentivecompatible contract can be implemented, the strength of the incentives included in the...

Incentives often distort behavior: they induce agents to exert effort but this effort is not employed optimally. This paper proposes a theory of incentive design allowing for such distorted behavior. At the heart of the theory is a trade-off between getting the agent to exert effort and ensuring...

We present a model in which a motivator can take costly actions - or what we call motivational effort - in order to reduce the effort costs of a worker, and analyze the optimal combination of motivational effort and monetary incentives. We distinguish two cases. First, the firm owner chooses the...

This paper models two key roles of subjective performance evaluations: their incentive role and their feedback role. The paper shows that the feedback role makes subjective pay feasible even without repeated interaction, as long as there exists some verifiable measure of performance. It also...

I develop an agency model in which performance measurement and compensation contracts are jointly used to shape incentives. When an agent has extensive control over firm value, there tend to be many optimal measures — each implying a unique optimal contract with a strikingly simple closed form...

This paper is an extensive review of agency theory applied to labour incentives. It introduces a generalised principal-agent model that goes through a certain degree of critical assessment. The analysis of the optimality within the trade-off of insurance against incentives is enriched by...

In many organizations, employees enjoy significant discretion regarding project selection. If projects differ in their informativeness about an employee’s quality, project choices will be distorted whenever career concerns are important. We analyze a model in which an organization can shape...

We study optimal incentive contracts for workers who are reciprocal to management attention. When neither worker's effort nor manager's attention can be contracted, a double moral-hazard problem arises, implying that reciprocal workers should be given weak financial incentives. In a...
