Existence of pure strategy equilibria among geographically dispersed firms
نویسنده
چکیده
This paper gives a proof of existence of price equilibria under certain parameters for a model of product differentiation commonly used in the empirical geographic differentiation literature. This proof is needed because the assumptions of Caplin and Nalebuff (1991) are not generally satisfied once data is introduced to geographic models. The theorem also has implications for existence in mixed−logit demand models. Citation: Thomadsen, Raphael, (2005) "Existence of pure strategy equilibria among geographically dispersed firms."

Price and capacity competition
We study the efficiency of oligopoly equilibria in a model where firms compete over capacities and prices. Our model economy corresponds to a two-stage game. First, firms choose their capacity levels. Second, after the capacity levels are observed, they set prices. Given the capacities and prices, consumers allocate their demands across the firms. We establish the existence of pure strategy oli...
متن کاملOn the existence of equilibria in discontinuous games: three counterexamples
We study whether we can weaken the conditions given in Reny [4] and still obtain existence of pure strategy Nash equilibria in quasiconcave normal form games, or, at least, existence of pure strategy ε−equilibria for all ε > 0. We show by examples that there are: 1. quasiconcave, payoff secure games without pure strategy ε−equilibria for small enough ε > 0 (and hence, without pure strategy Nash...
متن کاملOME WORKING PAPER SERIES Supply Function Equilibria Always Exist
Supply function equilibria are used in the analysis of divisible good auctions with a large number of identical objects to be sold or bought. An important example occurs in wholesale electricity markets. Despite the substantial literature on supply function equilibria the existence of a pure strategy Nash equilibria for a uniform price auction in asymmetric cases has not been established in a g...
متن کاملOligopoly with Capacity Constraints and Thresholds
Abstract Extended Oligopoly models will be introduced and examined in which the firms might face capacity limits, thresholds for minimal and maximal moves, and antitrust thresholds in the case of partial cooperation. Similar situation occurs when there is an additional cost of output adjustment, which is discontinuous at zero due to set-up costs. In these cases the payoff functions of the...
متن کاملOn the Existence of Pure Strategy Nash Equilibria in Large Games∗
We consider an asymptotic version of Mas-Colell’s theorem on the existence of pure strategy Nash equilibria in large games. Our result states that, if players’ payoff functions are selected from an equicontinuous family, then all sufficiently large games have an ε – pure, ε – equilibrium for all ε > 0. We also show that our result is equivalent to Mas-Colell’s existence theorem, implying that i...
