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 ...
Consistent Rationalizability
(Université de Montréal. Département de sciences économiques., 2002)
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. ...
Similarity of Options and the Measurement of Diversity
(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 ...
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 ...
Upper Semicontinuous Extensions of Binary Relations
(Université de Montréal. Département de sciences économiques., 2002)
Suzumura shows that a binary relation has a weak order extension if and only if it is consistent. However, consistency is demonstrably not sufficient to extend an upper semi-continuous binary relation to an upper semicontinuous ...
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 ...
Rational Choice on Arbitrary Domains: A Comprehensive Treatment
(Université de Montréal. Département de sciences économiques., 2005)
The rationalizability of a choice function on arbitrary domains by means of a transitive relation has been analyzed thoroughly in the literature. Moreover, characterizations of various versions of consistent rationalizability ...
Dynamic Measures of Individual Deprivation
(Université de Montréal. Département de sciences économiques., 2005)
We introduce and axiomatize a one-parameter class of individual deprivation measures. Motivated by a suggestion of Runciman, we modify Yitzhaki’s index by multiplying it by a function that is interpreted as measuring the ...
Population Ethics and the Value of Life
(Université de Montréal. Département de sciences économiques., 2003)
Public policies often involve choices of alternatives in which the size and the composition of the population may vary. Examples are the allocation of resources to prenatal care and the design of aid packages to developing ...
Harsanyi’s Social Aggregation Theorem : A Multi-Profile Approach with Variable-Population Extensions
(Université de Montréal. Département de sciences économiques., 2003)
This paper provides new versions of Harsanyi’s social aggregation theorem that are formulated in terms of prospects rather than lotteries. Strengthening an earlier result, fixed-population ex-ante utilitarianism is ...
