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 ...
Flippable Pairs and Subset Comparisons in Comparative Probability Orderings and Related Simple Games
(Université de Montréal. Département de sciences économiques., 2006-10)
We show that every additively representable comparative probability order on n atoms is determined by at least n - 1 binary subset comparisons. We show that there are many orders of this kind, not just the lexicographic ...
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 ...
First-Degree Discrimination by a Duopoly: Pricing and Quality Choice
(Université de Montréal. Département de sciences économiques., 2005-01)
Sharing a River among Satiable Countries
(Université de Montréal. Département de sciences économiques., 2006-07)
With diminishing global water reserves the problem of water allocation becomes increasingly important. We consider the problem of efficiently sharing a river among a group of satiable countries. Inducing countries to ...
Sharing the Cost of a Public Good: an Incentive-Constrained Axiomatic Approach
(Université de Montréal. Département de sciences économiques., 2006-07)
We study the problem of provision and cost-sharing of a public good in large economies where exclusion, complete or partial, is possible. We search for incentive-constrained efficient allocation rules that display fairness ...
Resource egalitarianism with a dash of efficiency
(Université de Montréal. Département de sciences économiques., 2007-05)
Preference Heterogeneity in Monetary Policy Committees
(Université de Montréal. Département de sciences économiques., 2007-05)
On Complexity of Lobbying in Multiple Referenda
(Université de Montréal. Département de sciences économiques., 2006-10)
In this paper we show that lobbying in conditions of “direct democracy” is virtually impossible, even in conditions of complete information about voters preferences, since it would require solving a very computationally ...
