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. ...
Efficient and Non-Deteriorating Choice
(Université de Montréal. Département de sciences économiques., 2002)
We analyze collective choice procedures with respect to their rationalizability by means of profiles of individual preference orderings. A selection function is a generalization of a choice function where selected alternatives ...
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 ...
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 ...
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 ...
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.
Efficient Strategy-Proof Allocation Functions in Linear Production Economies
(Université de Montréal. Département de sciences économiques., 1998)
In a linear production model, we characterize the class of efficient and strategy-proof allocation functions, and the class of efficient and coalition strategy-proof allocation functions. In the former class, requiring ...
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 ...
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 ...
