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...

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...

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. Assuming that knowledge...

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 proposes a Schumpeterian growth model generalizing the existing theory : we exploit the formalization of a circular product differentiation model of Salop (1979) to take into account the fact that knowledge inherent in a given sector can diffuse variously among R&D sectors, ranging...

The possibility of capturing and sequestering some fraction of the CO2 emissions arising from fossil fuel combustion, often labeled as carbon capture and storage (CCS), is drawing an increasing amount of attention in the business and academic communities. We present here a model of endogenous...

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 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...
