On the Evolution of Individualistic Preferences: Complete Versus Incomplete Information Scenarios.

We study the evolution of preferences via payoff monotonic dynamics in strategic environments with and without complete information. It is shown that, with complete information and subgroup matching, empirically plausible interdependent preference relations may entail the local instability of individualistic preferences (which target directly the maximization of material payoffs/fitness). The said instability may even be global if the subgroup size is large enough. In contrast, under incomplete information (unobservability of preference types), we show that independent preferences are globally stable in a large set of environments, and locally stable in essentially any standard environment, provided that the number of subgroups that form in thesociety is large. Since these results are obtained within the context of a very general model, they may be thought of as providing an evolutionary rationale for the prevalence of individualistic preferences.EVOLUTION; PREFERENCES; INCOMPLETE INFORMATION.

Revealed Group Preferences on Non-Convex Choice Problems.

This paper studies the conditions under which the basic results of the re vealed preference theory can be established on the domain of choice problems which include non-convex feasible sets, the exercice is closely related to the works of Peters and Wakker (1991) and Bossert (1994).BARGAINING;RATIONAL CHOICE

Evolution of Interdependent Preferences in Aggregative Games

We study the evolution of preference interdependence in aggregative games which are symmetric with respect to material payoffs but asymmetric with respect to player objective functions. Specifically, some players have interdependent preferences (in the sense that they care not only about their own material payoffs but also about their payoffs relative to others) while the remainder are (material) payoff maximizers in the standard sense.PREFERENCE CHOICES
