Say it again: if everyone chose 1, then everyone's best response would be to choose 1, so that would be a Nash Equilibrium.

So if we know people are not going to play a best response that's never a best response, and we know if we people are not going to play something which is never a best response, and we know people are not going to play which is not a best response, which is not a best etc., etc., etc.

如果我们知道人们不会采用最佳对策,说错了,是不会采用非最佳对策,如果我们知道人们不会采用,非最佳对策的策略,就知道人们不会采用非最佳对策的策略,以此类推了

If Firm II is charging C, Then a best response for Firm 1 is to set price equal to marginal costs, and if Firm 1 is pricing at marginal cost, then conversely a best response for Firm 2 is to price at marginal cost.

如果公司2选择了C,公司1的最佳对策是,定价在边际成本,如果公司1定价在边际成本,同样的,公司2的最佳对策,也是定价在边际成本

If Player II chooses 4, then the synergy leads Player I to raise his best response all the way up to 2, but these strategies up here above 2 are never a best response for Player I. Is that right?

如果参与人II选4,协同导致,参与人I的最佳对策变成2,参与人I的那些大于2的策略,也永远不会成为最佳对策,对不对

So strategy ?i is a best response to the strategy S-i of the other players if my payoff from choosing ?i against S-i, is weakly bigger than that from choosing Si' against S- i, and this better hold for all possible other strategies I could choose.

策略?i是其他参与人策略S-i的,最佳对策,如果此时我选?i的收益,弱优于此情况下选Si'的收益,这对于所有我可以选择的策略都成立
