Decisive Coalitions and Coherence Properties
(Université de Montréal. Département de sciences économiques., 2009-03)
In a seminal contribution, Hansson has demonstrated that the family of decisive coalitions associated with an Arrovian social welfare function forms an ultrafilter. If the population under consideration is infinite, his ...
Quasi-Transitive and Suzumura Consistent Relations
(Université de Montréal. Département de sciences économiques., 2009-03)
We examine properties of binary relations that complement quasi-transitivity and Suzumura consistency in the sense that they, together with the original axiom(s), are equivalent to transitivity. In general, the conjunction ...
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 ...
Maximal-Element Rationalizability
(Université de Montréal. Département de sciences économiques., 2002)
We examine the maximal-element rationalizability of choice functions with arbitrary do-mains. While rationality formulated in terms of the choice of greatest elements according to a rationalizing relation has been analyzed ...
Domain Closedness Conditions and Rational Choice
(Université de Montréal. Département de sciences économiques., 2005)
The rationalizability of a choice function on an arbitrary domain under various coherence properties has received a considerable amount of attention both in the long-established and in the recent literature. Because domain ...
Rational Choice on Arbitrary Domains: A Comprehensive Treatment
(Université de Montréal. Département de sciences économiques., 2005)
The rationalizability of a choice function on arbitrary domains by means of a transitive relation has been analyzed thoroughly in the literature. Moreover, characterizations of various versions of consistent rationalizability ...
Upper Semicontinuous Extensions of Binary Relations
(Université de Montréal. Département de sciences économiques., 2002)
Suzumura shows that a binary relation has a weak order extension if and only if it is consistent. However, consistency is demonstrably not sufficient to extend an upper semi-continuous binary relation to an upper semicontinuous ...
Consistent Rationalizability
(Université de Montréal. Département de sciences économiques., 2002)
Consistency of a binary relation requires any preference cycle to involve indifference only. As shown by Suzumura (1976b), consistency is necessary and sufficient for the existence of an ordering extension of a relation. ...
