“…The respective literature has produced several appealing results on the existence of Nash equilibrium, the order structure of the equilibrium set, and monotone comparative statics without resorting to the standard topological assumptions on players' strategy sets or utility functions (see Amir, 1996; Milgrom & Roberts, 1990; Milgrom & Shannon, 1994; Roy & Sabarwal, 2008, 2010; Topkis, 1979; Vives, 1990; Zhou, 1994).
