Should principals explain and justify their evaluations? Suppose the principal s evaluation is private information, but she can provide justification by sending a costly unverifiable message. If she does not provide justification, her message space is restricted, but the message is costless. I...

We analyze optimal labor contracts when the worker is inequity averse towards the employer. Welfare is maximized for an equal sharing rule of surplus between the worker and the firm. That is, profit sharing is optimal even if effort is contractible. If the firm can make a take-it-or leave-it...

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...

This paper analyzes two-stage rank-order tournaments. A principal decides (i) how to spread prize money across the two periods, (ii) how to weigh performance in the two periods when awarding the second-period prize, and (iii) whether to reveal performance after the rst period. The information...

Humans reciprocate. We want to return favors we have received, but also respond appropriately to behavior that we regard as unfair against us. Whereas previous research has typically tried to isolate the most prominent explanations for reciprocal behavior - inherent preferences for reciprocity...

This paper investigates whether the timing of rewards affects behavior in multi-stage contests. Abstracting from discounting, theory predicts that it is irrelevant for behavior whether agents are immediately rewarded for succeeding on a particular stage, or whether the reward is delayed until...

We study a setting in which one or two agents conduct research on behalf of a principal. The agents binary performance level (suc- cess or failure) depends on their invested research e ort, and their choice of a research technology that is uncertain in respect of its apt- ness to generate a...

I consider a setting of complete but unverifiable information in which two agents enter a contractual relationship to induce mutually beneficial investments. As my main result, I establish that the famous irrelevance of contracting paradigm, that arises due to the detrimental effect of...

This paper analyzes the relationships between the degree of decentralization of public policy and the emergence of horizontal strategic interactions. We analyze the structural funds allocation process in determining how the structure of governance of cohesion policy a ects the development of...

We propose a theory of ex post inefficient renegotiation that is based on loss aversion. When two parties write a long-term contract that has to be renegotiated after the realization of the state of the world, they take the initial contract as a reference point to which they compare gains and...
