We consider a model with two energy sources, a non-renewable one, cheap but polluting, and a renewable one, expensive but clean, let’s say coal and solar. The aim of environmental policy is to maintain atmospheric carbon concentration under a given ceiling, chosen to prevent an excessive rise...

Consider a general equilibrium framework where the marginal cost of extraction from several deposits of an exhaustible resource is constant in terms of an inexhaustible perfect substitiute and differs between deposits. The instantaneous rate of productionfrom the inexhaustible resourcce is...

Using the Chakravorty et al. (2006) ceiling model, we characterize the optimal consumption paths of three energy resources: dirty oil, which is non-renewable and carbon emitting; clean oil, which is also non-renewable but carbon-free thanks to an abatement technology, and solar energy, which is...

[eng] Is there Cause for Concern over the Drop in Aquifer Levels ? . by Jean-Pierre Amigues, Pascal Favard and Michel Moreaux . This paper analyses the problems raised when managing continental aquifers replenished by the trickledown of surface water. These aquifers can be regarded as natural...

Using the Chakravorty et al. (J Econ Dyn Control 30:2875–2904, <CitationRef CitationID="CR6">2006</CitationRef>) ceiling model, we characterize the optimal consumption paths of three energy resources: dirty oil, which is non-renewable and carbon emitting; clean oil, which is also non-renewable but carbon-free thanks to an abatement...</citationref>

Inside a standard growth model with exhaustible resources, we study the optimal growth policy of an economy submitted to a climate constraint, taking the form of a ceiling over admissible atmospheric carbon concentrations. The optimal scenario is a three phases path: a rise of carbon...
