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 ...
Resource egalitarianism with a dash of efficiency
(Université de Montréal. Département de sciences économiques., 2007-05)
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 ...
Relative Egalitarianism and Related Criteria
(Université de Montréal. Département de sciences économiques., 2009-02)
We reconsider the problem of aggregating individual preference orderings into a single social ordering when alternatives are lotteries and individual preferences are of the von Neumann-Morgenstern type. Relative egalitarianism ...
An Axiomatization of the Serial Cost-Sharing Method
(Université de Montréal. Département de sciences économiques., 2009-12)
We o¤er an axiomatization of the serial cost-sharing method of Friedman and Moulin (1999). The key property in our axiom system is Group Demand Monotonicity, asking that when a group of agents raise their demands, not all ...
Top-Cycle Rationalizability
(Université de Montréal. Département de sciences économiques., 2005)
We identify necessary and sufficient conditions for the choice set from every subset A of a (finite) universal set X to coincide with the top cycle in A of some fixed tournament on X.
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 ...
Aumann-Shapley Pricing : A Reconsideration of the Discrete Case
(Université de Montréal. Département de sciences économiques., 2004)
We reconsider the following cost-sharing problem: agent i = 1,...,n demands a quantity xi of good i; the corresponding total cost C(x1,...,xn) must be shared among the n agents. The Aumann-Shapley prices (p1,...,pn) are ...
Responsibility and Cross-Subsidization in Cost Sharing
(Université de Montréal. Département de sciences économiques., 2002)
We propose two axiomatic theories of cost sharing with the common premise that agents demand comparable -though perhaps different- commodities and are responsible for their own demand. Under partial responsibility the ...
