We present a model of endogenous growth in which the use of a non-renewable resource in production yields CO2 emissions whose accumulated stock negatively affects welfare. A CCS technology enables, via some effort, a partial reduction of these emissions.

The paper considers an endogenous growth model with climate change as well as three R&D sectors dedicated to energy, CCS (Carbon Capture and Storage) and backstop efficiency. First, we characterize the set of decentralized equilibria: a particular equilibrium is associated with any vector of...

[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...

There is a wide consensus among international institutions and national governments in favor of compact (i.e. densely populated) cities as a way to improve the ecological performance of the transport system. Indeed, when both the intercity and intra-urban distributions of activities are given, a...

We analyze the impact of input tariffs on the export status and export performance of heterogeneous processing firms. Using a theoretical model with downstream firms exhibiting different levels of productivity, we show that lower input tariffs may increase the export sales of high-productivity...
