今天在整理以前的东西的时候 翻到了以前的赛局理论考卷 这一题让我在考试的时候想了很久 最後还是放弃做答了 不知道板上的强者是否可以为我说明一下 这一题到底该怎麽解??? Consider a market with 10 firms. Simultaneously and independently, the firms choose between locating downtown and locating in the suburbs. The profit of each firm is influenced by the number of other firms that locate in the same area. Specifically, the profit of a firm that locates downtown is given by 5n – n2 + 50, where n denotes the number of firms that locate downtown . Similarly, the profit of a firm that locates in the suburbs is given by 48 – m, where m denotes the number of firms that locate in the suburbs. In equilibrium, how many firms locate in each region and what is the profit of each? 我那时候只有想到一个很基本的观念 就是如果今天有A和B两个人 假设其它条件相同 则店家会把店开在A和B的中点 但是这题是两个不同的地点 且有代数字下去算 不知道我想到的那个观念可不可以套进来应用?? --
