La plupart des organisations, sinon toutes, répartissent d'une manière ou d'une autre des coûts communs entre leurs diverses composantes ou encore entre leurs différents partenaires. Ces problèmes de partage de coûts communs se posent avec de plus en plus d'acuité car les règles de...

Une véritable valorisation des infrastructures communes doit reposer sur une approche rigoureuse du partage de leurs coûts et de leur tarification implicites sinon explicites. D'où l'intérêt et la pertinence du présent ouvrage qui se veut à la fois un regroupement en un seul lieu et une...

In this paper, we present the different cost sharing methods one can find in the economic literature. We regroup the methods into three sets : the proportional methods, the cooperative game theory methods and the serial cost sharing methods. All those methods are presented through the stylized...

It is important that the choice of a cost sharing method be made on the basis of its general equity and consistency properties rather than on the basis of the results it may generate in a given application. In this paper, we partition the different methods according to whether they satisfy a...

In order to choose the proper size of an infrastructure and to save as much as possible on investment costs, it is necessary for the responsible party (the Centre in the language of this report) to have access to information that is typically known only by some agents or partners who may use...

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...
