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...

[fre] Nous présentons un modèle de croissance endogène dans lequel l’utilisation d’une ressource naturelle non renouvelable polluante génère des émissions de CO2, dont une partie peut être séquestrée. Ceci rompt l’habituel lien systématique entre utilisation de la ressource et...

[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...

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...

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)...
