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 ...
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 ...
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 ...
Every Choice Function is Backwards-Induction Rationalizable
(Université de Montréal. Département de sciences économiques., 2013-01)
A choice function is backwards-induction rationalizable if there exists a finite perfect-information extensive-form game such that, for each subset of alternatives, the
backwards-induction outcome of the restriction of ...
Inclusive fitness maximization: an axiomatic approach
(Université de Montréal. Département de sciences économiques., 2013-05)
Kin selection theorists argue that evolution in social contexts will lead organisms to behave as if maximizing their inclusive, as opposed to personal, fitness. The inclusive fitness concept allows biologists to treat ...
Single-basined choice
(Université de Montréal. Département de sciences économiques., 2013-06-03)
Single-basined preferences generalize single-dipped preferences by allowing for multiple worst elements. These preferences have played an important role in areas such as voting, strategy-proofness and matching problems. ...
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 ...
