Relative Egalitarianism and Related Criteria
(Université de Montréal. Département de sciences économiques., 2009-02)
We reconsider the problem of aggregating individual preference orderings into a single social ordering when alternatives are lotteries and individual preferences are of the von Neumann-Morgenstern type. Relative egalitarianism ...
An Axiomatization of the Serial Cost-Sharing Method
(Université de Montréal. Département de sciences économiques., 2009-12)
We o¤er an axiomatization of the serial cost-sharing method of Friedman and Moulin (1999). The key property in our axiom system is Group Demand Monotonicity, asking that when a group of agents raise their demands, not all ...
A Note on Ordinally Equivalent Pareto Surfaces
(Université de Montréal. Département de sciences économiques., 1997)
Assuming at least three individuals and some regularity conditions, we construct a set S* of Pareto surfaces which is an ordinal basis of the set S of all surfaces: every surface in S is ordinally equivalent to some surface ...
Size invariant measures of association: characterization and difficulties
(Université de Montréal. Département de sciences économiques., 2014-08)
A measure of association is row-size invariant if it is unaffected by the multiplication of all entries in a row of a cross-classification table by a same positive number. It is class-size invariant if it is unaffected by ...
Ordinally consistent tournament solutions
(Université de Montréal. Département de sciences économiques., 2016-03)
A set ranking method assigns to each tournament on a given set an ordering of the subsets of that set. Such a method is consistent if (i) the items in the set are ranked in the same order as the sets of items they beat and ...
Ranking by rating
(Université de Montréal. Département de sciences économiques., 2016-02)
Each item in a given collection is characterized by a set of possible performances. A (ranking) method is a function that assigns an ordering of the items to every performance profile. Ranking by Rating consists in evaluating ...
Relative Nash welfarism
(Université de Montréal. Département de sciences économiques., 2017-09)
Relative Nash welfarism is a solution to the problem of aggregating von Neumann-Morgenstern preferences over a set of lotteries. It ranks such lotteries according to the product of any collection of 0-normalized von ...
Strategyproof Choice of Acts : Beyond Dictatorship
(Université de Montréal. Département de sciences économiques., 2017-05)
We model social choices as acts mapping states of nature to (public) outcomes. A social choice function (or SCF) assigns an act to every profile of subjective expected utility preferences over acts. A SCF is strategyproof ...
Top-Cycle Rationalizability
(Université de Montréal. Département de sciences économiques., 2005)
We identify necessary and sufficient conditions for the choice set from every subset A of a (finite) universal set X to coincide with the top cycle in A of some fixed tournament on X.
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 ...
