Rationalizability and Efficiency in an Asymmetric Cournot Oligopoly.
Desgranges, Gabriel; Gauthier, Stéphane - Centre d'Économie de la Sorbonne, Université Paris 1 … - 2014
We study rationalizable solutions in a linear asymmetric Cournot oligopoly. We show that symmetry across firms favors multiplicity of rationalizable solutions: A merger (implying a greater asymmetry across firms) makes out-of-equilibrium behavior less likely and should dampen &lquo;coordination&rquo;...

On the Structure of Rationalizability for Arbitrary Spaces of Uncertainty
Penta, Antonio - Department of Economics, University of Pennsylvania - 2008
This note characterizes the set A¡∞ of actions of player ¡ that are uniquely rationalizable for some hierarchy of beliefs on an arbitrary space of uncertainty. It is proved that for any rationalizable action a¡ for the type t¡, if a¡ belongs to A¡∞ and is justified by conjectures...

Dominance-solvable common-value large auctions
Azrieli, Yaron; Levin, Dan - In: Games and Economic Behavior 73 (2011) 2, pp. 301-309
We consider second-price common-value auctions with an increasing number of bidders. We define a strategy of bidder i to be (ex-post, weakly) asymptotically dominated if there is another strategy for i that does, in the limit, as well against any sequence of strategies of iʼs opponents, and...

Local contraction-stability and uniqueness
Hefti, Andreas M. - 2013
In this paper we analyze R&D collaboration networks in industries where firms are competitors in the product market. Firms' benefits from collaborations arise by sharing knowledge about a cost-reducing technology. By forming collaborations, however, firms also change their own competitive...

Local contraction-stability and uniqueness
Hefti, Andreas M. - Institut für Volkswirtschaftslehre, … - 2013
This paper investigates the relationship between uniqueness of Nash equilibria and local stability with respect to the …, local stability and uniqueness are the same formal properties of the game. With equilibrium substitutes, local stability is … equilibria of symmetric games more stable. Finally, the relationship between the stability of the Nash best-response dynamics is …
