古诺模型与伯川德模型的区别有哪些?为什么同是对寡头垄断厂商的均衡的解释却有不同的结论？

最好能附上参考文献

Answer 1

古诺模型是厂商选择产量，价格由市场决定。伯川德是厂商选择价格，且在给定价格的情况下每个厂商生产足够的产品来迎合市场需求

Answer 2

Two classical models in the theory of oligopoly are those of Cournot (1838) and Bertrand (1883). In both models the equilibrium concept is the noncooperative equilibrium of Nash (1950). In the former firms set quantities. In the latter prices are the strategy variables. In a duopoly situation where firms produce a homogeneous good and marginal costs are constant and equal for both firms, the Bertrand price equals marginal cost and the Cournot price is above it. With differentiated products, Bertrand prices are above marginal cost. In this case Cournot competition is still viewed as more "monopolistic" than Bertrand competition.
