... and µ2 , and for any a = (a1 , a2 ) ∈ A, µ (a) = µ1 (a1 )·µ2 (a2 ) Yet another way to look at what is happening is to say that if we pick a ∈ A according to µ, then the random variables πAi (a) ... games, dominant strategies, rationalizable strategies, and correlated equilibria 2.1 Generalities about static games One specifies a game by specifying who is playing, what actions they can take, ... A caveat: a (s) is not defined for for any s’s having margS (p)(s) = By convention, an optimal plan can take any value in A for such s Notation: we will treat the point-to-set mapping s → a ...
