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 ...
Revealed Preference and Choice under Uncertainty
(Université de Montréal. Département de sciences économiques., 2010-11-06)
We employ the theory of rational choice to examine whether observable choices from feasible sets of prospects can be generated by the optimization of some underlying
decision criterion under uncertainty. Rather than ...
Product Filters, Acyclicity and Suzumura Consistency
(Université de Montréal. Département de sciences économiques., 2010-11-25)
In a seminal contribution, Hansson (1976) demonstrates that the collection of
decisive coalitions associated with an Arrovian social welfare function forms an ultrafilter. He goes on to show that if transitivity is weakened ...
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. ...

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 ...
Expected utility without full transitivity
(Université de Montréal. Département de sciences économiques., 2014-05)
We generalize the classical expected-utility criterion by weakening transitivity to Suzumura consistency. In the absence of full transitivity, reflexivity and completeness no longer follow as a consequence of the system ...
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 ...
