This paper studies a dynamic adjustment process in a large society of forward-looking agents where payoffs are given by a normal form supermodular game. The stationary states of the dynamics correspond to the Nash equilibria of the stage game. It is shown that if the stage game has a monotone...

We show that in all (whether generic or nongeneric) binary-action supermodular games, an extreme action profile is robust to incomplete information if and only if it is a monotone potential maximizer. The equivalence does not hold for nonextreme action profiles
