Single-Peaked Choice
(Université de Montréal. Département de sciences économiques., 2006-09)
Single-peaked preferences have played an important role in the literature ever since they were used by Black (1948) to formulate a domain restriction that is sufficient for the exclusion of cycles according to the majority ...
Non-Deteriorating Choice without Full Transitivity
(Université de Montréal. Département de sciences économiques., 2006-08)
Although the theory of greatest-element rationalizability and maximal-element rationalizability under general domains and without full transitivity of rationalizing relations is well-developed in the literature, these ...
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 ...
Social Norms and Rationality of Choice
(Université de Montréal. Département de sciences économiques., 2007)
Ever since Sen (1993) criticized the notion of internal consistency of choice, there exists a wide spread perception that the standard rationalizability approach to the theory of choice has difficulties coping with the ...
Population Ethics
(Université de Montréal. Département de sciences économiques., 2006-09)
This paper reviews the welfarist approach to population ethics. We provide an overview of the critical-level utilitarian population principles and their generalized counterparts, examine important properties of these ...
Measuring Economic Insecurity
(Université de Montréal. Département de sciences économiques., 2009-03)
We provide a systematic treatment of the notion of economic insecurity, assuming that an individual’s sentiment of insecurity depends on the current wealth level and its variations experienced in the past. We think of ...
Multi-Profile Intertemporal Social Choice
(Université de Montréal. Département de sciences économiques., 2012-08)
We provide a brief survey of some literature on intertemporal social choice theory in a multi-profile setting. As is well-known, Arrow’s impossibility result hinges on
the assumption that the population is finite. For ...
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 ...
Revealed Preference and Choice under Uncertainty
(Université de Montréal. Département de sciences économiques., 2010-11-06)
We employ the theory of rational choice to examine whether observable choices from feasible sets of prospects can be generated by the optimization of some underlying
decision criterion under uncertainty. Rather than ...
Product Filters, Acyclicity and Suzumura Consistency
(Université de Montréal. Département de sciences économiques., 2010-11-25)
In a seminal contribution, Hansson (1976) demonstrates that the collection of
decisive coalitions associated with an Arrovian social welfare function forms an ultrafilter. He goes on to show that if transitivity is weakened ...
