A fixed point theorem for discontinuous functions

Herings, Peter Jean-Jacques; Laan, Gerard van der; … - 2004

Any function from a non-empty polytope into itself that is locally gross direction preserving is shown to have the fixed point property. Brouwer's fixed point theorem for continuous functions is a special case. We discuss the application of the result in the area of non-cooperative game theory.

Perfection and stability of stationary points with applications to noncooperative games

Laan, Gerard van der; Talman, Dolf; Yang, Zaifu - 2002

well known refinements of the Nash equilibrium, namely, perfect Nash equilibrium and proper Nash equilibrium, are special … Nash equilibrium is shown to exist for every game. In symmetric bimatrix games, our results imply the existence of a … symmetric proper equilibrium. Applying our results to the field of evolutionary game theory yields a refinement of the …

Static stability in games

Milchtaich, Igal (contributor) - 2008

Static stability of equilibrium in strategic games differs from dynamic stability in not being linked to any particular … dynamical system. In other words, it does not make any assumptions about off-equilibrium behavior. Examples of static notions of …-discrete strategy spaces. -- Stability of equilibrium ; static stability …

Voting in small networks with cross-pressure

Andina-Díaz, Ascensión (contributor); … - 2006

We present a model of participation in elections in small networks, in which citizens suÞer from cross-pressures if voting against the alternative preferred by some of their social contacts. We analyze how the existence of cross-pressures may shape voting decisions, and so, political outcomes;...
