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? -- ※ 發信站: 批踢踢實業坊(ptt.cc), 來自: 114.27.104.56 ※ 文章網址: http://www.ptt.cc/bbs/Economics/M.1396454887.A.AD2.html

當然不行，題目說oligopolistic，是寡占，怎可看成完競。

equilibrium is competitive equilibrium, where p= mc.
