Single-Peaked Choice
(Université de Montréal. Département de sciences économiques., 2006-09)
Single-peaked preferences have played an important role in the literature ever since they were used by Black (1948) to formulate a domain restriction that is sufficient for the exclusion of cycles according to the majority ...
Non-Deteriorating Choice without Full Transitivity
(Université de Montréal. Département de sciences économiques., 2006-08)
Although the theory of greatest-element rationalizability and maximal-element rationalizability under general domains and without full transitivity of rationalizing relations is well-developed in the literature, these ...
Flippable Pairs and Subset Comparisons in Comparative Probability Orderings and Related Simple Games
(Université de Montréal. Département de sciences économiques., 2006-10)
We show that every additively representable comparative probability order on n atoms is determined by at least n - 1 binary subset comparisons. We show that there are many orders of this kind, not just the lexicographic ...

Sharing the Cost of a Public Good without Subsidies
(Université de Montréal. Département de sciences économiques., 2006-07)
We study the construction of a social ordering function for the case of a public good financed by contributions from the population, and we extend the analysis of Maniquet and Sprumont (2004) to the case when contributions ...
A Characterization of Consistent Collective Choice Rules
(Université de Montréal. Département de sciences économiques., 2006-08)
We characterize a class of collective choice rules such that collective preference relations are consistent. Consistency is a weakening of transitivity and a strengthening of acyclicity requiring that there be no cycles ...
Free Triples, Large Indifference Classes and the Majority Rule
(Université de Montréal. Département de sciences économiques., 2007-03)
Self-Selective Social Choice Functions
(Université de Montréal. Département de sciences économiques., 2006-11)
It is not uncommon that a society facing a choice problem has also to choose the choice rule itself. In such situation voters’ preferences on alternatives induce preferences over the voting rules. Such a setting immediately ...
