This paper explores risk-sharing and equilibrium in a general equilibrium set-up wherein agents are non-additive expected utility maximizers. We show that when agents have the same convex capacity, the set of Pareto-optima is independent of it and identical to the set of optima of an economy in...

We show that essentially every communication equilibrium of any finite Bayesian game with two players can be implemented as a strategic form correlated equilibrium of an extended game, in which before choosing actions as in the Bayesian game, the players engage in a possibly fin nitely long (but...

On the basis of the concept of compromise, this research in progress deals with the development of an Information System of competencies management. Based on the Actor Network Theory approach (Law, 1992; Callon, 2001; Akrich, Callon and Latour, 2002a,b; Latour, 2005), the concept of compromise helps us...
