Optimal Contracts under Moral Hazard and Costly Lying
Keeyoung Rhee (Korea Development Institute)Year 2021Vol. 37No. 1
AbstractWe present a model in which the agent reports a privately observed signal about the stochastic outcome of her action, while bearing a cost of misreporting her private information. If the agent receives a low payment contingent on her performance, it is very costly for the agent to misreport her information to the principal so that the principal makes a decision favorable to the agent. However, if the contingent compensation is too high, the principal will terminate the project unless the agent truthfully reports that the project is likely to give a high return. The optimal outcome is achieved by a contract with the fee structure loosely tied with the outcome, but the cost of lying is necessarily high.
