回答1：

这属于一种动态博弈，相依为邻，双方的策略和活动都能够及时反馈到对方那边，情报准确而及时，能够随时调整自我战略，另外，这又是一种合作竞争的关系，两者之间售卖的产品类似而不相同，能形成一种产品的销售氛围，达成良性竞争，做到相对平衡，在服务一个大类客户的同时又能在一定范围内提供差异化服务。

a famous application from politics

there are two candidates,they are choosing their political positions for an election.they are the players,and the strategies are going to be they're going to choose positions on a spectrum,on a political spectrum.we're going to assume that this political spectrum has ten positions,1 to 10.1 to left wing positions,then change into right wing positons when it's 10.we're assume that there are 10% of the voters at each of these positions,voters will eventually vote for the closest candidate,if there's a tie then the voters split.the payoff are that the candidates aim to maximize their share of the vote.

choosing 2 always gave 5% more votes than choosing 1,so we can conclude that 2 strictly dominates 1.so similarly,9 strictly dominates 10,regardless of what the other person chooses.but if we delete the strategies 1 and10,which were dominated,then does 3 dominated 2?2 and 9 are not dominated,but they are dominated once we realize 1 and 10 won't be played.so if we do the procedure of interative of deletion of dominated strategies,all that's left is 5 and 6.in the end,"it del" leads to deleting all except 5 and 6.that the candidates are going to be squeezed towards the middle.this is the "Median Voter Theorem".for example,the Kennedy Nixon Election in 1960.

in politics,this is about candidates crowding close together towards the center,to try and get as many voters who are close to them.in economics,this is about firm's crowding together to try and get shoppers who are close to them.

不好意思，今天有点晚了，这是我自己做的点笔记，你将就看吧，简单说就是个中间投票定理，在政治上是表现为候选人表现出趋向中间的立场以获取更多的选民，在经济上就是商家聚集以某些人流密集处以获取客源。我是自学的，表达的不是很清楚，给你地址，是耶鲁的公开课，这节是在第三课后半部分。
