Extensive Social Choice and the Measurement of Group Fitness in Biological Hierarchies
(Université de Montréal. Département de sciences économiques., 2012-07)
Extensive social choice theory is used to study the problem of measuring group fitness in a two-level biological hierarchy. Both fixed and variable group size are considered. Axioms are identified that imply that the group ...
Intertemporal Material Deprivation
(Université de Montréal. Département de sciences économiques., 2012-06)
Individual well-being is multidimensional and various aspects of the quality of life

Consistent Relations
(Université de Montréal. Département de sciences économiques., 2006)
Consistency, a natural weakening of transitivity introduced in a seminal contribution by Suzumura (1976b), has turned out to be an interesting and promising concept in a variety of areas within economic theory. This paper ...
Domain Closedness Conditions and Rational Choice
(Université de Montréal. Département de sciences économiques., 2005)
The rationalizability of a choice function on an arbitrary domain under various coherence properties has received a considerable amount of attention both in the long-established and in the recent literature. Because domain ...
Anonymous Single-Profile Welfarism

This note reexamines the single-profile approach to social-choice theory. If an alternative is interpreted as a social state of affairs or a history of the world, it can be argued that a multi-profile approach is inappropriate ...
Interpersonal Comparisons of Well-Being
(Université de Montréal. Département de sciences économiques., 2004)
This paper, which is to be published as a chapter in the Oxford Handbook of Political Economy, provides an introduction to social-choice theory with interpersonal comparisons of well-being. We argue that the most promising ...
The Possibility of Ordering Infinite Utility Streams
(Université de Montréal. Département de sciences économiques., 2004)
This paper revisits Diamond’s classical impossibility result regarding the ordering of infinite utility streams. We show that if no representability condition is imposed, there do exist strongly Paretian and finitely ...
