摘要
信息经济学是非对称信息博弈论在经济学中的应用 ,主要研究什么是非对称信息情况下的最优契约。经济学中的委托———代理关系泛指任何一种涉及非对称信息的交易 ,即在交易过程中 ,拥有信息优势的一方被称为代理人 (agent)而另一方则称为委托人 (principal)。参与人在动态博弈中的行为可能完全不同于静态博弈中的行为。这一结论对于委托代理关系而言 ,同样是成立的。道德风险是信息经济学中委托———代理关系的核心问题。类似锦标制度的激励合同可能是解决委托人道德风险问题的一个有效办法。如果存在着信息不对称问题 ,委托权的分配就复杂得多了 ;此时 ,最优委托权的安排不仅要考虑到风险态度的问题 ,而且还要考虑到激励问题。经营者之所以是委托人 ,是因为经营者的行为最为重要又最难监督。
The Information Economics is a result of asymmetric information Game theory application into economics. It is study what is a most action contract. The principal-agent relation in economics is the exchange that relate to asymmetric information. In the course trade-off, have information advantage is agent, and that another is principal. The action of player can complete be differ from in dynamic game then static game. The result is tenable for principal-agent relation. Moral hazard is a core issue in the principal-agent relation. An incentive contract resemble rank-order may is an efficiency moth to solve the moral hazard of principal. If have asymmetric problem, the distribution of principal is more complexity, for the most action principal arrange not only considering the attitude for risk, and considering the incentive problem. The manager is principal, for the manager's action most importance and most hard supervise.
