How does renegotiation affect contracts between a principal and an agent subject to persistent private information and moral hazard? This paper introduces a concept of renegotiation-proofness, which adapts to stochastic games the concepts of weak renegotiation-proofness and internal consistency...

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...

Abstract Traditionally in economics the actions of agents have been viewed as driven exclusively by individuals' interest in their own wealth. Nonetheless experimental evidence shows that agents enjoy being richer than their peers or, in other words, agents are interested in their status within...

I study a continuous time principal-agent model in which an unknown parameter and the agent's hidden effort affect the distribution of observable outcomes. The principal and the agent learn about the parameter by observing past outcomes. The agent's current effort has an implicit long-term...

We consider how a principal can optimally outsource information acquisition to an agent in a dynamic environment when the principal can observe neither the agent's effort of collecting information nor signal realizations. Neither initial transaction nor interim payments are allowed to prevent...
