摘　　要：采用一个三阶段价格领先博弈模型研究Cartel的稳定值特征.发现当产业规模较小的时候,Cartel稳定值可以是全联盟或者包含大多数厂商.另外,稳定Cartel的规模受厂商的成本水平影响,产业中的厂商越是成本有效,结果越趋于全合作.然而,当产业规模足够大且厂商成本足够高时,均衡结果只包含3个厂商.In this paper,the size of stable cartel in the symmetric price leadership model is characterized.It is found that the stable cartel could be a grand coalition or a large coalition with most of firms involved in the industry when the size of the industry is small.Moreover, the size of stable dominant cartel varies according to cost levels of firms,the more cost-efficient the firms are,the more likely full cooperation appears.However,full cooperation would not be supported as an equilibrium outcome when the industry size is large and the cost of production is high enough.In this case,a unique small cartel with only three firms prevails.
