Supermodular Games

چکیده
These notes develop the theory of supermodular games. Supermodular games are those characterized by “strategic complementarities” – roughly, this means that when one player takes a higher action, the others want to do the same. Supermodular games are interesting for several reasons. First, they encompass many applied models. Second, they have the remarkable property that many solution concepts yield the same predictions. Finally, they tend to be analytically appealing – they have nice comparative statics properties and behave well under various learning rules. Much of the theory is due to Topkis (1979), Vives (1990) and Milgrom and Roberts (1990).

A Survey on Supermodular Games
Supermodular games are an interesting class of games that exhibits strategic complementarity. There are several compelling reasons like existence of pure strategy nash equilibrium, dominance solvability, identical bounds on joint strategy space etc. that make them a strong candidate for game theoretic modeling of economics. Supermodular games give a sound framework for analysis as it is based o...
متن کاملMonotone Equilibria in Nonatomic Supermodular Games. a Comment * Lukasz Balbus †
Recently Yang and Qi (2013) stated an interesting theorem on the existence of complete lattice of equilibria in a particular class of large nonatomic supermodular games for general action and players spaces. Unfortunately, their result is incorrect. In this note, we detail the nature of the problem with the stated theorem, provide a counterexample, and then correct the result under additional a...
متن کاملOn equilibrium refinements in supermodular games
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 equilibria may contain weakly dominated actions. Moreover, in discontinuous supermodular games satisfying sequential better-reply security, perfect equilibr...
متن کاملMonotone and Local Potential Maximizers in Symmetric 3× 3 Supermodular Games∗
Generalized notions of potential maximizer, monotone potential maximizer (MP-maximizer) and local potential maximizer (LPmaximizer), are studied. It is known that 2 × 2 coordination games generically have a potential maximizer, while symmetric 4 × 4 supermodular games may have no MPor LP-maximizer. This note considers the case inbetween, namely the class of (generic) symmetric 3 × 3 supermodula...

متن کاملAbstract Interpretation of Supermodular Games
Supermodular games find significant applications in a variety of models, especially in operations research and economic applications of noncooperative game theory, and feature pure strategy Nash equilibria characterized as fixed points of multivalued functions on complete lattices. Pure strategy Nash equilibria of supermodular games are here approximated by resorting to the theory of abstract i...
