متن کاملOn the Existence of Cournot Equilibrium without Concave Profit Functions*
This communication is concerned with the existence of equilibrium in Cournot’s model of oligopoly [2, Chap. VII]. This question, of course, has been examined often (see, e.g., [l-3]). To our knowledge, however, all previous treatments of the problem have assumed (either directly or indirectly) that the reaction curves of the firms are single-valued continuous functions or convex-valued, upper h...
متن کاملA Unifying Pair of Cournot-Nash Equilibrium Existence Results
For games with a measure space of players a tandem pair, consisting of a mixed and a pure Cournot–Nash equilibrium existence result, is presented. Their generality causes them to be completely mutually equivalent. This provides a unifying pair of Cournot–Nash existence results that goes considerably beyond the central result of E. J. Balder (1995, Int. J. Game Theory 24, 79–94, Theorem 2.1). Th...
متن کاملStackelberg versus Cournot Equilibrium
We reconsider Stackelberg’s classical critique of the Cournot duopoly, in the framework of endogenous timing for two-player games. For quantity duopoly we provide different sets of minimal conditions, directly on the demand and cost functions, yielding respectively the simultaneous and the two sequential modes of play. While our findings essentially confirm the predominance of the former, they ...
متن کاملExistence of Equilibrium and Comparative Statics in Differentiated Goods Cournot Oligopolies
We show that under horizontal differentiation pure symmetric Cournot equilibria exist if firms react to a rise in competitors’ output in such a way that their market price does not rise. This condition is related to strategic complementarity, but not to convexity or differentiability. We rule out multiple equilibria under some additional conditions and discuss stability and regularity of equili...
