Optimal Incentives under Moral Hazard: From Theory to Practice
George Georgiadis, Associate Professor of Strategy, Kellogg School of Management, Northwestern University,

Abstract: This paper addresses the following practical question: given an existing incentive contract, what information must a manager acquire to determine how to improve upon that contract? We use a canonical principal-agent framework under moral hazard and assume the principal has productivity data corresponding to some status quo contract. Our main result shows that if the principal has a priori information about the agent's marginal utility function, and she carries out an experiment in which she perturbs the existing contract, she can estimate how the agent will respond to a change in his marginal incentives, as well as how the agent's marginal incentives will respond to any other perturbed contract. The information provided by such an experiment, therefore, serves as a sufficient statistic for the question of how best to locally improve upon the existing contract. The same informational requirements hold, and an analogous sufficient statistic result is obtained, when the principal is restricted to choosing from a lower-dimensional parametric class of contracts; e.g., linear contracts. We also describe the informational requirements for assessing global optimality, where local information like the type we described above is insufficient.
