This report characterizes the regulation of energy markets in general and focuses on the electricity and natural gas markets of Québec. Markets are regulated if they are deemed to represent natural monopoly situations or if unregulated firms would not take into account externalities that they...

Ce rapport aborde la question de la réglementation des marchés de l'énergie en général en mettant l'accent sur les marchés de l'électricité et du gaz naturel. On réglemente des marchés si l'on juge qu'ils représentent des situations de monopole naturel ou si l'on a des raisons de...

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...

(Sous la direction de Michel Poitevin) Impartition et sous-traitance apparaissent souvent comme des synonymes : pourtant, les deux termes recoupent des réalités distinctes. La sous-traitance renvoie aux modalités - économiques ou légales - de toute forme de délégation. L'impartition...

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...

We model capacity-building investments in a homogeneous product duopoly facing uncertain demand growth. Capacity building is achieved through the addition of production units that are durable and lumpy and whose cost is irreversible. While building their capacity over time, firms compete à la...

The general interest would require that the use of major equipments be priced at their marginal cost, including all opportunity costs such as congestion and pollution costs. At least, prices should be lowered until full utilization of these equipments is obtained. This is a result that...
