We consider a population of agents, either finite or countably infinite, located on an arbitrary...
Trees and Extensive Forms (with Klaus Ritzberger), Journal of Economic Theory (2008)

Nash Equilibria for Non-Binary Choice Rules (with José Carlos R. Alcantud), International Journal of Game Theory (2007)
(Also known as <strong>Choice-Nash Equilibria</strong>) We prove the existence of equilibria in games with players...

We consider partial bandwagon properties in the context of coordination games to capture the idea...
A Simple Characterization of Approval Voting, Social Choice and Welfare (2006)
This note provides a characterization of Approval Voting as the only ballot aggregation function satisfying...

We consider a model of evolution and local interactions in a circular city as in...
The Discretization of Continuum Strategy Spaces, International Game Theory Review (2006)
When the strategy set of a game is a continuum, its discretization may not conserve...
Some Remarks on Pseudotrees (with Klaus Ritzberger), Order (2005)
This paper provides new results on pseudotrees. First, it is shown that pseudotrees are precisely...

Random Matching of Several Infinite Populations, Annals of Operations Research (2002)
Random matching models with infinite populations present formal difficulties due to the lack of a...
Local Equilibria in Economic Games (with Ana B. Ania), Economics Letters (2001)
We study solution concepts for economic games that are resistant to local deviations. Strategy spaces...
An Evolutionary Model of Bertrand Oligopoly (with Ana B. Ania and Klaus R. Schenk-Hoppé), Games and Economic Behavior (2000)
