Principal-agent problem
What is the principal-agent problem?
A principal-agent problem can arise when a person or organization delegates an action to another party whose interests differ, especially when relevant information or actions are difficult to observe. The delegating party is the principal; the acting party is the agent.
Hidden actions and incentives
Holmström’s analysis (1979) examines a hidden-action problem in which incentives must be balanced against risk sharing. Paying for measured outcomes can change effort incentives while exposing an agent to risks outside their control.
Principal-agent problem example
A homeowner may gain substantially from a higher sale price, while a commissioned agent receives only a fraction of that increase and must spend more time finding the buyer. They may therefore value a quick sale differently. This illustrates a possible incentive conflict; it does not tell us what a particular agent will do.
Responses to the principal-agent problem
Monitoring and compensation arrangements are possible responses, with costs and trade-offs. The useful task is to specify the delegated action, available information, incentives, and observed outcomes.
Moral hazard is one problem associated with actions that are difficult to observe.
