Admissible Hierachic Sets
(2005-05)
In this paper we present a solution concept for abstract systems called the admissible hierarchic set. The solution we propose is a refinement of the hierarchic solution, a generalization of the von Neumann and Morgenstern ...
The Stability of the Roommate Problem Revisited
(2007-09)
The lack of stability in some matching problems suggests that alternative solution concepts to the core might be applied to find predictable matchings. We propose the absorbing sets as a solution for the class of roommate ...
The Supercore for Normal Form Games
(2003-10)
We study the supercore of a system derived from a normal form game. For the case of a finite game with pure strategies, we define a sequence of games and show that the supercore of that system coincides with the set of ...
The von Neumann-Morgenstern stable sets for 2x2 games
(Departamento de Fundamentos del Análisis Económico IDepartamento de Economía Aplicada IV, 2012-11)
We analyze the von Neumann and Morgenstern stable sets for the mixed extension of 2 2 games when only single profitable deviations are allowed. We show that the games without a strict Nash equilibrium have a unique vN&M ...
