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 ...
Deprivation and Social Exclusion
(Université de Montréal. Département de sciences économiques., 2004)
Social exclusion manifests itself in the lack of an individual’s access to functionings as compared to other members of society. Thus, the concept is closely related to deprivation. We view deprivation as having two basic ...
Anonymous Single-Profile Welfarism
(Université de Montréal. Département de sciences économiques., 2004)
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 ...
Relative Uncertainty and Additively Representable Set Rankings
(Université de Montréal. Département de sciences économiques., 2004)
This paper proposes a definition of relative uncertainty aversion for decision models under complete uncertainty. It is shown that, for a large class of decision rules characterized by a set of plausible axioms, the new ...
Reference Groups and Individual Deprivation
(Université de Montréal. Département de sciences économiques., 2004)
We provide an axiomatization of Yitzhaki’s index of individual deprivation. Our result differs from an earlier characterization due to Ebert and Moyes in the way the reference group of an individual is represented in the ...
Intertemporal Social Evaluation
(Université de Montréal. Département de sciences économiques., 2005)
Intertemporal social-evaluation rules provide us with social criteria that can be used to assess the relative desirability of utility distributions across generations. The trade-offs between the well-being of different ...
Critical-Level Population Principles and the Repugnant Conclusion
(Université de Montréal. Département de sciences économiques., 2002)
Critical-level generalized-utilitarian population principles with positive critical levels pro-vide an ethically attractive way of avoiding the repugnant conclusion. We discuss the axiomatic foundations of critical-level ...
Maximal-Element Rationalizability
(Université de Montréal. Département de sciences économiques., 2002)
We examine the maximal-element rationalizability of choice functions with arbitrary do-mains. While rationality formulated in terms of the choice of greatest elements according to a rationalizing relation has been analyzed ...
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 ...
