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,然后用P=MC解吗?

当然不行，题目说oligopolistic，是寡占，怎可看成完竞。

还是用MC=MR?这个应该是bertrand model吧

可用p=mc

这似乎是同质Bertrand 的样子...

P=MCWhen firms are selling identical products, the Bertrandequilibrium is competitive equilibrium, where p= mc.
