对信息不对称问题的重新思考

Reconsiderations on the Issue of Information Asymmetry

自阿克洛夫以来,经济理论界在研究信息不对称问题时,由于受传统刻画不确定性方法的束缚,没有认识到个人在做出决策时对其他参与者的类型集的主观估计的重要作用,因此缺乏对某些问题的现实解释力。对传统理论的假设做出合理的改变,才能拓展对信息不对称问题的研究途径,得出新的结论。

Economic theory studies on issues of information since Akerlof, limited by the traditional way of describing uncertainties, is not capable of realizing the importance of the individual subjective estimation of the other participators＇ type sets, and consequently it cannot explain quite a lot of practical problems satisfactorily. In this paper, we change the hypothesis of traditional theory, open up research ways to Information asymmetry, and draw new conclusions.
