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 ...
Fair Allocation of Production Externalities: Recent Results
(Université de Montréal. Département de sciences économiques., 2005)
We survey recent axiomatic results in the theory of cost-sharing. In this litterature, a method computes the individual cost shares assigned to the users of a facility for any profile of demands and any monotonic cost ...
Nearly Serial Sharing Methods
(Université de Montréal. Département de sciences économiques., 2004)
A group of agents participate in a cooperative enterprise producing a single good. Each participant contributes a particular type of input; output is nondecreasing in these contributions. How should it be shared? We analyze ...
Rationalizability of Choice Functions on General Domains without Full Transitivity
(Université de Montréal. Département de sciences économiques., 2001)
The rationalizability of a choice function by means of a transitive relation has been analyzed thoroughly in the literature. However, not much seems to be known when transitivity is weakened to quasi-transitivity or ...
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 ...
Sharing a River
(Université de Montréal. Département de sciences économiques., 2000)
A group of agents located along a river have quasi-linear preferences over water and money. We ask how the water should be allocated and what money transfers should be performed. We are interested in efficiency, stability ...
Core Retionalizability in Two-Agent Exchange Economies
(Université de Montréal. Département de sciences économiques., 2000)
We provide a characterization of selection correspondences in two-person exchange economies that can be core rationalized in the sense that there exists a preference profile with some standard properties that generates the ...
Non-Deteriorating Choice
(Université de Montréal. Département de sciences économiques., 2001)
We analyze an alternative to the standard rationalizability requirement for observed choices by considering non-deteriorating selections. A selection function is a generalization of a choice function where selected ...
What Is a Commody? Two Axiomatic Anwers
(Université de Montréal. Département de sciences économiques., 2001)
We identify conditions under which preferences over sets of consumption opportunities can be reduced to preferences over bundles of \"commodities\". We distinguish ordinal bundles, whose coordinates are defined up to ...
Fair Production and Allocation of an Excludable Nonrival Good
(Université de Montréal. Département de sciences économiques., 2002)
We study fairness in economies with one private good and one partially
excludable nonrival good. A social ordering function determines for each profile of
preferences an ordering of all conceivable allocations. We propose ...
