Hence, there are two pure strategy equilibria, (H, D) and (D, H).In addition, there is a mixed strategy equilibrium in which each player selects H with probability 2/3..

Webthe strategy set S. i, let S − i (B i) be the set of mixed strategyprofiles s. − i such that B i = B i (s − i).We can find all mixed strategy equilibria as follows. Consider each profile B of subsets B. i, and calculate theprofile (S. − i (B i)) I. The mixed strategy s is a Nash Equilibrium if: s. − i belongs to S − i (B i) for all ... WebOkay. you know, we see there, there are going to be games that have mixed strategy equilibria. in particular, zero sum and competitive games will tend to have them in, in a lot of situations. players have to be indifferent between what they, the players that they're facing. That gives you some very, interesting comparative statics. you know?
