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 ?
想請問這個可以看成完全競爭市場,然後用P=MC解嗎?

當然不行，題目說oligopolistic，是寡占，怎可看成完競。

還是用MC=MR?這個應該是bertrand model吧

可用p=mc

這似乎是同質Bertrand 的樣子...

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