We modify the principal-agent model with moral hazard by assuming that the agent is expectation-based loss averse according to Köszegi and Rabin (2006, 2007). The optimal contract is a binary payment scheme even for a rich performance measure, where standard preferences predict a fully...

This paper studies collusion in one-shot auctions, where a buyer can bribe his competitors into lowering their bids. We modify the single-unit Vickrey auction to incite deviations from the designated-winner scenario and thus undermine collusion. The construction of mechanism does not require the...

We study experimentally the effectiveness of communication in common value committees exhibiting publicly known heterogeneous biases. We test models assuming respectively self-interested and strategic, joint payoff-maximizing and cognitively heterogeneous agents. These predict varying degrees of...

The paper develops a technique for studying incentive problems with unidimensional hidden characteristics in a way that is independent of whether the type set is nite, the type distribution has a continuous density, or the type distribution has both mass points and an atomless part. By this...

We consider a principal-agent model with moral hazard where the agent’s knowledge about the performance measure is ambiguous and he is averse towards ambiguity. We show that the principal may optimally provide no incentives or contract only on a subset of all informative performance measures....

Consider managers evaluating their employees’ performances. Should managers justify their subjective evaluations? Suppose a manager’s evaluation is private information. Justifying her evaluation is costly but limits the principal’s scope for distorting her evaluation of the employee. I...
