Cooperative VS. Non-cooperative Truels: Little Agreement, but Does that Matter?
(Université de Montréal. Département de sciences économiques., 2000)
It is well-known that non-cooperative and cooperative game theory may yield different solutions to games. These differences are particularly dramatic in the case of truels, or three-person duels, in which the players may ...
Ranking Sets of Objects
(Université de Montréal. Département de sciences économiques., 2001)
We provide a survey of the literature on ranking sets of objects. The interpretations of those set rankings include those employed in the theory of choice under complete uncertainty, rankings of opportunity sets, set ...
In Defense of Welfarism
(Université de Montréal. Département de sciences économiques., 2002)
This paper characterizes welfarist social evaluation in a multi-profile setting where, in addition to multiple utility profiles, it is assumed that there are several profiles of non-welfare information. We prove new versions ...
Efficient and Non-Deteriorating Choice
(Université de Montréal. Département de sciences économiques., 2002)
We analyze collective choice procedures with respect to their rationalizability by means of profiles of individual preference orderings. A selection function is a generalization of a choice function where selected alternatives ...

Consistency of a binary relation requires any preference cycle to involve indifference only. As shown by Suzumura (1976b), consistency is necessary and sufficient for the existence of an ordering extension of a relation. ...

(Université de Montréal. Département de sciences économiques., 2002)
This paper analyzes the measurement of the diversity of sets based on the dissimilarity of the objects contained in the set. We discuss axiomatic approaches to diversity measurement and examine the considerations underlying ...
