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...

The "green paradox" literature points out that environmental policies which are anticipated to become gradually more stringent over time may induce a more rapid extraction of fossil fuels, thus having a detrimental effect to the environment. The manifestation of such phenomena has been...

We study an economy in which a final good is produced by two sectors. One uses a non-renewable and polluting resource, the other a renewable and clean resource. A specific type of research is associated to each sector. The public authorities levy a carbon tax and simultaneously subsidize both...

We study how the availability of an abatement technology affects the optimal use of polluting exhaustible resources, and optimal climate policies. We develop a Romer endogenous growth model in which the accumulated stock of greenhouse gas emissions harms social welfare. Since the abatement...

This paper examines the implications of an environmental policy for growth performances. We develop a model where growth is driven by human capital accumulation. Firms invest in research to develop new technologies to reduce their pollution emissions and education is treated as product which not...

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...

Cet article présente un modèle de croissance schumpetérien, qui généralise la théorie existante : nous utilisons la différenciation circulaire du modèle de Salop [1979] pour prendre en compte le fait que la connaissance se diffuse, avec plus ou moins d’ampleur, entre les secteurs de...

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...
