The goal of this paper is to contribute to the economic literature on ethnic and cultural diversity by proposing a new index that is informationally richer and more flexible than the commonly used ‘ethno-linguistic ...
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 ...
An axiomatic characterization of the MVSHN group fitness ordering
(Université de Montréal. Département de sciences économiques., 2012-09)
In order to analyze a unicellular-multicellular evolutionary transition, a multicellular organism is identified with the vector of viabilities and fecundities of its constituent cells. The Michod–Viossat–Solari–Hurand–Nedelcu ...
Single-Plateaued Choice

Single-plateaued preferences generalize single-peaked preferences by allowing for multiple best elements. These preferences have played an important role in areas such as voting, strategy-proofness and matching problems. ...
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 ...
Multi-Profile Intertemporal Social Choice
(Université de Montréal. Département de sciences économiques., 2012-08)
We provide a brief survey of some literature on intertemporal social choice theory in a multi-profile setting. As is well-known, Arrow’s impossibility result hinges on
the assumption that the population is finite. For ...
