主导厂商定价之后.外围厂商积极参与市场价格制定.被称作为数量领先模型.而在主导厂商定价后,外围厂商仅仅作为价格接受者而不参与价格制定.则被称作为价格领先模型.通过比较不同外围厂商行为的两种模型.发现当外围厂商参与市场价格确定时,稳定的Cartel规模较大.而当外围厂商不参与价格确定,只是价格接受者时.Cartel规模较小.最后用数值计算的方法对比检验了在两种模型下Cartel稳定值的大小.
After the dominant firm pricing, the peripheral manufacturers actively involved in the market price is called the number-leading model.And in the dominant manufacturer pricing, the peripheral manufacturers only as a price taker and not involved in price-making is called the price-leading model.By comparing We find that Cartel is stable when the peripheral firms participate in the market price determination, while Cartel is smaller when the peripheral firms do not participate in the price determination but only the price recipients. Finally, The method contrasts the size of the Cartel stability under both models.
