We first show that(More)
We show that supermodular games satisfying sequential better-reply security possess a pure strategy perfect equilibrium and a strategically stable set of pure strategy equilibria. We illustrate that in continuous supermodular games, perfect equi-libria may contain weakly dominated actions. Moreover, in discontinuous supermod-ular games satisfying sequential(More)
