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 ...
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 ...
Sharing the Cost of a Public Good without Subsidies
(Université de Montréal. Département de sciences économiques., 2006-07)
We study the construction of a social ordering function for the case of a public good financed by contributions from the population, and we extend the analysis of Maniquet and Sprumont (2004) to the case when contributions ...
A Characterization of Consistent Collective Choice Rules
(Université de Montréal. Département de sciences économiques., 2006-08)
We characterize a class of collective choice rules such that collective preference relations are consistent. Consistency is a weakening of transitivity and a strengthening of acyclicity requiring that there be no cycles ...
