标题[请益] 研究所考题-寡占
时间Thu Apr 3 00:08:05 2014
An oligopolistic market consists 3 firms which involve price competition
and produce an identical product. They have the same marginal cost mc=25
and no other costs. The market demand is P = 625 - 2Q. The equilibrium
demand of each firm is ? And the price is ?
想请问这个可以看成完全竞争市场,然後用P=MC解吗?
