International differences in fuel taxation are huge, and may be justified by different local negative externalities that taxes must correct, as well as by different preferences for public spending. In this context, should a worldwide unique carbon tax be added to these local taxes to correct the...

In this paper, we study the real and financial effects of insider trading in the spirit of Jain and Mirman (1999). Unlike the previous works that address this issue, we suppose that the production of the real good is costly and depends mainly of the price of an intermediate good produced locally...

If raising and educating children is a private cost to households, while the availability of skilled labor supply resulting from the households' fertility and education choices is a public good, then competitive equilibria typically deliver a suboptimal mix of size and skills of the population....

This paper analyzes the environmental tax policy issues when labor is heterogeneous. The objective is to assess whether an environmental tax policy could be Pareto improving, when the revenue of the pollution tax is recycled by a change in the labor tax properties. We show that, depending on the...

This paper tries to go beyond regulation regimes to depict national uses of flexibility. On the basis of a company survey we are able to assess that a significant number of Danish firms applies a mix of internal and external modes of flexibility simultaneously. The second part of our analysis...

The aim of this paper is twofold : to highlight the relationship between the types of change affecting organisations and modes of job separation (economic redundancy, dismissal on personal grounds or resignation), and to cast light on the process that leads to job separation. It relies upon both...

The core of a cooperative game on a set of players $N$ is one of the most popular concepts of solution. When cooperation is restricted (feasible coalitions form a subcollection $\cF$ of $2^N$), the core may become unbounded, which makes its usage questionable in practice. Our proposal is to make...

The collective model assumes that decisions taken inside the family are Pareto optimal. However, empirical studies cast doubts upon the efficiency assumption, especially on the production side of household decision making. In this paper, we present a model of household behavior including a...

We study the situation of an agent who can trade on a financial market and can also transform some assets into others by means of a production system, in order to price and hedge derivatives on produced goods. This framework is motivated by the case of an electricity producer who wants to hedge...

La simulation informatique a permis aux disciplines dépourvues de la possibilité de réaliser des expériences de se doter d'outils leur permettant d'évaluer leurs hypothèses et leurs modèles. Elle reste toutefois cantonnée à l'intégration numérique de modèles mathématiques ou...
