[eng] Game Theory offers the natural tool for a theoretical analysis of markets. Its usefulness becomes evident in the analysis of imperfect competition. To illustrate this theme we first examine the analysis of price competition stemming from the Bertrand- Edgeworth model which has led to the...

[eng] Educational Choices, General Equilibrium and Economic Growth, . by Antoine d'Autume.. . A proper understanding of the role of human capital in economic growth is best achieved in a framework where microeconomic educational choices are imbedded in a general equilibrium model. We therefore...

[ger] Kointegration und dynamische Modelle, . von Antoine d'Autume.. . Die Integrations- und Kointegrationseigenschaften spiegeln wichtige dynamische Eigenschaften der makroökonomischen Modelle wider, die wir unter Aufzeigung der engen Beziehungen zwischen den deterministischen Eigenschaften...

[eng] A Medium-Run Model of the French Economy . by Antoine d''Autume and Alain Quinet . This paper presents a simple small-scale model of the French economy, which can be used for forecasting and assessing shocks and macroeconomic policies. We model a small open economy with fixed exchange...

This paper studies the maximin paths of the canonical Dasgupta-Heal-Solow model when the stock of natural capital is a direct argument of well-being, besides consumption. Hartwick's rule then appears as an efficient tool to characterize solutions in a variety of settings. We start with the case...

Following Stollery (1998), we extend the Solow-Dasgupta-Heal model to analyze the effects of global warming. The rise in temperature is caused by the use of fossil resources so that the temperature level can be linked to the remaining stock of these resources. The rise in temperature affects...

This article offers a new method of solution for linear difference equations with rational expectations. The author provides a description of the complete set of solutions, which is shown to depend on arbitrary martingales. The author thus avoids the use of "differences of martingales," as...

[fre] Nous nous intéressons à l'imposition du revenu, entendue dans un sens très large puisque nous y incluons l'impôt négatif que constitue le versement de subventions accordées sous conditions de revenu. Dans le barème actuel, les taux marginaux d'imposition ont un profil en U. La...
