问题如下图:

选项:

A.

B.

C.

解释:

这个题为什么只用考虑S open/prop,然后就比较表格上方的左右两列。不用继续讨论T open/prop嘛?

纳什均衡的题目做法可以先假定一个不变 对比该情况下的另外两个。即先考虑S open,之后对比在S open 的情况下T利润最大的是哪个。

需要讨论T的,我们会在之后进行讨论,这种题目不要着急,慢慢比对就好。可参考下面的具体方法:

首先我们先假定SigmaSoft-Open,也就是说先只看第一列。在S-Open的情况下来寻找ThetaTech利润的最大化。(此时忽略S后的数字,只看T后的数字)。第一列下T数字最大的是600。锁定第一个大方框。

其次假定S-Prop。也就是说看第二列。第二列下只看T后的数字,最大为700。锁定第二个大方框。

第三部就是比较第一个方框和第二个方框。假定T-open,找出S后面的最大值,即650.为第二个方框。因此最终确定是SigmaSoft-Prop,ThetaTech-open

这个感觉跟先找的比较对象关系很大,比如: 如果先假定T-Prop,那么锁定第一列下面方框,S-open; 其次假定T-open,那么锁定第二列上面方框,S-prop; 接下来怎么比较?
