[eng] Worksharing : from legal constraint to bargaining. . . The purpose of this paper is to study the effect of various worksharing policies on employment. The first part is devoted to a partial equilibrium analysis. A compulsory reduction in work hours, compulsory negotiation on hours, and...

[eng] Joint production and general equilibrium theory . . As it invalidates the Non-Substitution Theorem the joint production assumption was bound to create some problems for NeoRicardian theory. Our aim is to show that most of the paradoxes encountered in this approach disappear if one is...

[fre] Cet article présente une introduction critique à la nouvelle macro-économie classique, fondée sur l'hypothèse d'anticipations rationnelles. Nous reprenons un ensem­ble de modèles macro-économiques à la Sargent-Wallace pour analyser les thèmes caractéristiques de cette école et...

The first aim of this report is to present a synthesis of the analysis of pension schemes. We neglect any individual heterogeneity and focus on intertemporal trade-offs. The Diamond model shows that a pay-as- you-go pension scheme exerts a negative effect on saving and capital accumulation...

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...

Despite numerous efforts at interpretation and exposition, the standard Real Business Cycle model remains somewhat misterious. Its dynamic porperties are by now familiar, at least to those who made the effort to run simulation by themselves. Many extention of the basic model have been developed,...

Following Stollery (1998), we extend the Solow-- Dasgupta--Heal model to analyze the effects of global warming The rise of 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 of temperature affects...

The now standard WS- PS (wage-setting, price-setting) introduced by Layard-Nickell-Jackman(1991) and recently developped by Cahuc-Zylberberg(1999), provides simple foundations to the equilibrium unemployment rate. We provide a complete exposition of the model. We stress the importance of...
