不完全信息下贝叶斯纳什均衡的转化

Transformation of Bayesian Nash Equilibrium under Incomplete Information

本文从古诺特模型的一般分析出发,在完全信息和不完全信息两种条件下分别得出厂商各自的均衡利润,然后通过比较两种均衡下的利润大小去分析不完全信息条件下的均衡转化问题。之后把此结果推向一般情况,进一步分析了不完全信息贝叶斯纳什均衡向完全信息纳什均衡转化的条件以及其结论的意义。

From the general analysis of Coumot model ,this paper come to the profits of the two firms respectively under the conditions of complete information and incomplete information , then analyzes the equilibrium transformation of the incomplete information game by comparing two firms＇ profits under the two different conditions. At the last, after put the results to general cases it further analyzes the condition of the transformation from incomplete information Bayesian Nash equilibrium to complete information Nash equilibrium and also explains its practical application.
