Efficiency in Uncertain Cooperative Games
(Université de Montréal. Département de sciences économiques., 2001)
A contingent contract in a transferable utility game under uncertainty specifies an outcome for each possible state. It is assumed that coalitions evaluate these contracts by considering the minimal possible excesses. A ...
A Representation Theorem for Domains with Discrete and Continuous Variables
(Université de Montréal. Département de sciences économiques., 2001)
This paper proves a new representation theorem for domains with both discrete and continuous variables. The result generalizes Debreu's well-known representation theorem on connected domains. A strengthening of the standard ...
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 ...
The Axiomatic Approach to Population Ethics
(Université de Montréal. Département de sciences économiques., 2001)
This paper examines several families of population principles in the light of a set of axioms. In addition to the critical-level utilitarian, number-sensitive critical-level utilitarian and number-dampened families and ...
Ranking Sets of Objects
(Université de Montréal. Département de sciences économiques., 2001)
We provide a survey of the literature on ranking sets of objects. The interpretations of those set rankings include those employed in the theory of choice under complete uncertainty, rankings of opportunity sets, set ...
