Individuals with heterogeneous incomes occupy a territory divided into zones with unequal levels of amenities. Using the concept of land rent à la Ricardo, we propose a model determining the land rent in the different zones as well as the distribution of individuals across them. A land tax...

Nous introduisons le concept d'empreinte carbone dans un mod èle o ffre globale et demande globale avec formation imparfaitement concurrentielle des prix et salaires et en examinons les propriétés de l' équilibre en présence d'une politique climatique. Nous étudions deux instruments...

The paper focuses on the interactions between investment and non-cooperative wage bargaining when the investment decision of the firm bears irreversibly both on the size of the productive capacity and on the capital intensity of the technology used by the firm. The paper first shows how a given...

We survey the issue of environmental limits to growth in macroeconomic theory. We first analyse to what extent economic growth may be constrained in a world with finite natural resources. We next cover the topic of growth-induced environmental degradation. For both themes, we present the...

We reassess the issue of limits to growth in an endogenous growth model of a decentralized economy where final productions require a recyclable essential material input. The model relies on technological assumptions consistent with the material balance principle and on an explicit distinction...

We introduce the concept of carbon footprint into an aggregate demand and supply model with imperfectly competitive price and wage formation. We analyse the properties of the short-term macroeconomic equilibrium in the presence of a climate policy, which may take the form either of a carbon tax...

Dans un modèle de croissance endogène reposant sur le concept de soutenabilité forte et intégrant une ressource de matière (naturellement recyclable) dont la productivité marginale est bornée, cet article reconsidère la "conjecture de Ricardo", à savoir l'éventualité d'une hausse...

We study optimal carbon capture and storage (CCS), taking into account damages incurred from the accumulation of carbon in the atmosphere and exhaustibility of fossil fuel reserves. High carbon concentrations call for full CCS. We identify conditions under which partial or no CCS is optimal. In...
