摘要
信息不对称理论是微观经济学研究的一个核心内容,用来说明在不完全信息市场上,相关信息在交易双方的不对称分布对市场交易行为的影响,以及由此而产生的市场运行效率问题,经济学家为了解决这个问题提出了若干理论和模型,一定程度上解决了由于信息不对称带来的逆向选择和道德败坏问题,为合理利用市场资源要搜寻信息、市场信号、契约设计以及建立健全法律法规,不断改善宏观干预手段和方法、加强道德教育和社会监督的解决措施。
Asymmetric information theory is a core in Microeeonomics, which is used to describe the influence of information asymmetries on the market transactions in the uncompleted information market, as well as the resulting efficiency of market operations. In order to solve this problem, economists put forward a number of theoretical models. To a certain extent these models resolve the problem of adverse selection and moral hazard due to the asymmetric information, and to provide a solution for the rational use of available resources in the market .
