产品差异化、竞争类型与合谋稳定性分析

Product Differentiation,Competition Type and the Stability of Collusion

在分析产品差异化的问题上引入合谋成本,修正了以往认为古诺竞争比伯川德竞争的合谋更容易维持的认识,得出在合谋成本的临界值之上,伯川德竞争比古诺竞争的合谋更容易维持的结论,这为经济参与者和决策制定者分析合谋问题提供一个更加全面的视角.

This paper analyzesd the issue of product differentiation with the cost of collusion.The analysis shows that the past knowledge that the collusion is easier to maintain in Cournot competition than in Bertrand competition should be modified as follows： when the collusion cost is above some critical value,the collusion is easier to maintain in Bertrand competition than in Cournot competition,which provides a more comprehensive perspective for the economic analysis of collusion participants and decision makers.
