The consequences of environmental taxation on the supply of air transportation services by a profit-maximizing monopolist are examined. We consider both a passenger related tax and an aircraft related tax, highlight their respective impact on prices and frequency and derive their optimal...

We characterize sequential (preemption) and simultaneous (coordination) equilibria, as well as joint-value maximizing (cooperation) solutions, in a model of investment timing allowing for externalities in both flow pro...ts and investment costs. For two ex-ante symmetric ...rms, either...

In a real option model, we show that the standard analysis of vertical relationships transposes directly to investment timing. Thus, when a firm undertaking a project requires an outside supplier (e.g., an equipment manufacturer) to provide it with a discrete input to serve a growing but...

Collusion sustainability depends on firms' aptitude to impose sufficiently severe punishments in case of deviation from the collusive rule. We characterize the ability of oligopolistic firms to implement a collusive strategy when their ability to punish deviations over one or several periods...

Au sein des entreprises, la notion de RSE (Responsabilité Sociale des Entreprises) accroît notamment le besoin de pilotage de la performance environnementale. Dans ce contexte, cet article présente un outil d'évaluation mis en place de façon expérimentale au sein de la société TOTAL. Cet...

L'évolution des contextes décisionnels liés aux infrastructures de transport ets telle que, désormais, le décideur public est constamment soumis aux exigences de deux catégories de préoccupations: rationaliser l'utilisation des ressources publiques et faire des choix acceptables du point...

This paper presents the application of an approach designed to evaluate non-financial performance in companies. Within a defined perimeter, the approach called EPISSURE produces an "evaluation of non-financial performance with a hierarchical set of synthesis indicators co-constructed during a...

L'analyse coûts avantages est un outil d'évaluation des impacts potentiels des choix d'investissements publics. Dans de nombreux pays, en particulier la France, il est notamment mobilisé dans le cadre de processus de décision publique portant sur les investissements en infrastructures de...

We formulate some questions that may help an analyst to choose a multicriteria decision aiding method well adapted to the decision context. These questions take into account several aspects of the decision process and of the cooperation between the analyst and the decision maker. We present...
