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 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...

What is the social value of innovations in Schumpeterian growth models? This issue is tackled by introducing the concept of Lindahl equilibrium in a standard endogenous growth model with vertical innovations which is extended by explicitly considering knowledge diffusion on a Salop (1979)...

This paper analyzes the link between the fact that fully endogenous growth models exhibit (or not) the non-desirable scale effects property and assumptions regarding the intensity of knowledge diffusion. In that respect, we extend a standard Schumpeterian growth model by introducing explicitly...

We analyze the impact of the pollution generated by the use of non-renewable resources on the standard results of growth models. In this context, we obtain a Hotelling rule which is not a pure efficiency condition any longer. Subsequently, we show that some of the optimal paths’ standard...

This paper proposes a Schumpeterian growth model generalizing the existing theory: we exploit the Salop (1979) formalization of circular product differentiation to take into account the fact that knowledge can diffuse variously among R&D sectors, ranging from local to global diffusion. We...

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...
