Infinite-Horizon Choice Functions
(Université de Montréal. Département de sciences économiques., 2006)
We analyze infinite-horizon choice functions within the setting of a simple linear technology. Time consistency and efficiency are characterized by stationary consumption and inheritance functions, as well as a transversality ...
Strategy-proof preference aggregation
(Université de Montréal. Département de sciences économiques., 2012-08)
An aggregation rule maps each profile of individual strict preference orderings
over a set of alternatives into a social ordering over that set. We call such a rule strategyproof if misreporting one’s preference never ...
Every Choice Function is Backwards-Induction Rationalizable
(Université de Montréal. Département de sciences économiques., 2013-01)
A choice function is backwards-induction rationalizable if there exists a finite perfect-information extensive-form game such that, for each subset of alternatives, the
backwards-induction outcome of the restriction of ...
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 ...
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 ...
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 ...
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 ...
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. ...
