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 ...
Strategy-proof preference aggregation
(Université de Montréal. Département de sciences économiques., 2012-08)
An aggregation rule maps each profile of individual strict preference orderings
over a set of alternatives into a social ordering over that set. We call such a rule strategyproof if misreporting one’s preference never ...
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
need to be jointly considered in its measurement. The axiomatic literature on the
subject has proposed many indices of multidimensional ...
Single-plateaued choice
(Université de Montréal. Département de sciences économiques., 2012-05)
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 ...
Proximity-Sensitive Individual Deprivation Measures
(Université de Montréal. Département de sciences économiques., 2012-12)
We propose and characterize a generalization of the classical linear index of individual deprivation based on income shortfalls. Unlike the original measure, our class allows for increases in the income of a higher-income ...
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 ...
