We investigate whether having a unique equilibrium (or a given number of equilibria) is robust to perturbation of the payoffs, both for Nash equilibrium and correlated equilibrium. We show that the set of n-player finite games with a unique correlated equilibrium is open, while this is not true...

This article is devoted to a survey of results for differential games obtained through Viability Theory. We recall the basic theory for differential games (obtained in the 1990s), but we also give an overview of recent advances in the following areas : games with hard constraints, stochastic...

Alpha-Beta pruning is one of the most powerful and fundamental MiniMax search improvements. It was designed for sequential two-player zero-sum perfect information games. In this paper we introduce an Alpha-Beta-like sound pruning method for the more general class of “stacked matrix games”...

The article shows how Jean-Francois Mertens contributed to the development of game theory and microeconomics as we know them today. Along with about 80 articles, Mertens's topics go from the formulation of Bayesian decision making in games with incomplete information to the foundations of cost...

Questioning about game theory as an institutionalism theory could seem unsound at first glance. In game theory, the very basic concept of players’ strategies is quite individualistic and really independent on any social constraint and other institutional consideration. On another hand, the...

We examine the consequences on impairment testing disclosures of auditor-pair choice made by French listed companies where two (joint) auditors are required by law. Managers are likely to manipulate impairment-testing disclosures since it relies on unverifiable fair value estimates (e.g.,...
