International environmental agreements aiming at correcting negative externalities generated by transboundary pollution are difficult to achieve for many reasons. Important obstacles arise from asymmetry in costs and benefits, and instability may occur due to the fact that coalitions of...

In this paper we test empirically with the Nordhaus and Yang (1996) RICE model the core property of the transfer scheme advocated by Germain, Toint and Tulkens (1997). This scheme is designed to sustain full co-operation in a voluntary international environmental agreement by making all...

Calling upon both positive and normative economics, we attempt to characterise the issues at stake in the current international negotiations on climatic change. We begin (Section 2) by reviewing the main features of the Protocol. Then (Section 3), we identify by means of an elementary economic...

The paper proves the existence and uniqueness of a noncooperative steady state in the context of a model of climate change. It also explores the possibility of cooperation and attainment of an optimal steady state. It is shown that the problem is similar to that in the static model (Chander and...

In this paper we introduce the CLIMNEG World Simulation (CWS) model for simulating cooperative game theoretic aspects of global climate negotiations. The model is derived from the seminal RICE model by Nordhaus and Yang (1996). We first state the necessary conditions that determine optimal...

[fre] Nous testons économétriquement l’existence d’interactions fiscales entre les communes belges pour deux types d’impôts : les additionnels à l’impôt sur le revenu des personnes physiques (IPP) et au précompte immobilier (PrI). Un modèle dynamique est spécifié et estimé sur...

A discrete time "resource allocation process" bearing on international negotiations relating to SO2 transfrontier pollution between Finland, Russia and Estonia is formulated here as a sequence of solutions to successive non linear programs. A novel assumption concerning local information on...

On présente ici le point de vue de la science économique contemporaine sur l’alternative "structure unitaire" en matière d’organisation de l’Etat. Partant des objectifs économiques assignés à celui-ci, on examine comment ses fonctions allocatives, redistributives, macroéconomiques...
