[fre] Certains auteurs, tels P. Schou ou P. Aghion et P. Howitt, ont caractérisé les sentiers optimaux de croissance dans un modèle schumpétérien en présence d'une ressource non renouvelable. Le premier objectif de cet article est de montrer comment ces sentiers peuvent être implémentés...

Cet article étudie les effets sur l’efficacité de l’économie du choix des taxes environnementales nationales, en présence d’une pollution globale. Nous proposons un modèle dynamique à deux pays, où l’utilisation d’une ressource non-renouvelable génère des flux...

This paper extends the literature on the taxation of polluting exhaustible resources by taking international heterogeneities and national tax-setting into account. We propose a two-country Romer model of endogenous growth in which the South is endowed with the stock of an essential polluting...

We study the effects of an economic policy in an endogenous growth general equilibrium framework where production of consumption goods requires two resource inputs: a polluting non-renewable resource and a non-polluting labour resource. The use of the former contributes to the accumulation of...

This paper explores the trade-off between economic growth and environmental quality along two paradigms of endogenous growth theory: variety expansion (HIP) and quality improvements (VIP). We compare the policies that match the decentralised economies' paths with the optimal "strong sustainable"...

The paper considers a climate change growth model with three R&D sectors dedicated to energy, backstop and CCS (Carbon Capture and Storage) efficiency. First, we characterize the set of decentralized equilibria: A particular equilibrium is associated to each vector of public tools which includes...

We borrow standard assumptions from the non-renewable-resource-taxation and from the directed-technical-change literatures, to take a full account of the incentives to perform R&D activities in a dirty-resource sector and in a clean-resource-substitute sector. We show that a gradual rise in the...

This article deals with the impacts of national environmental taxes on economic efficiency when pollution is global. We propose a dynamic, two-country model where the use of a non-renewable resource generates emissions accumulating in a world stock of atmospheric pollution. We assume that the...
