We pursue the analysis of the Path Serial Cost Sharing Rule by examining how the cost share of an agent varies with respect to its own demand and the one of other agents. We also provide bounds for cost shares under an appropriate assumption on the cost function.

Cet article illustre les difficultés inhérentes au processus démocratique à partir des résultats d'une consultation tenue à l'Université Laval, dans le cadre de la nomination d'un doyen. Lors de ce scrutin, les votants devaient en principe ordonner tous les candidats, au nombre de quatre....

The Serial Cost Sharing Rule was originally conceived for situations where the demands of agents pertain to a homogeneous private good, produced by an unreplicable technology. In this context, it is endowed with a variety of desirable equity and coherency properties. This paper investigates the...

Drissi-Bakhkhat and Truchon ["Maximum Likelihood Approach to Vote Aggregation with Variable Probabilities," Social Choice and Welfare, 23, (2004), 161-185.] extend the Condorcet-Kemeny-Young maximum likelihood approach to vote aggregation by relaxing the assumption that the probability of...

If individual voters observe the true ranking on a set of alternatives with error, then the social choice problem, that is, the problem of aggregating their observations, is one of statistical inference. This study develops a statistical methodology that can be used to evaluate the properties of...

We approach the social choice problem as one of optimal statistical inference. If individual voters or judges observe the true order ona set of alternatives with error, then it is possible to use the set of individual rankings to make probability statements about the correct social order. Given...

The question addressed in this paper is the order of magnitude of the difference between the Borda rule and any given social choice function. A social choice function is a mapping that associates a subset of alternatives to any profile of individual preferences. The Borda rule consists in asking...

A voting situation, in which voters are asked to rank all candidates pair by pair, induces a tournament and a weighted tournament, in which the strenght of the majority matters. Each of these two tournaments induces in turn a two-player zero-sum game for which different solution concepts can be...
