The purpose of this paper is to show that not taking into account clearing costs does not allow to describe correctly the cultivated land dynamics when food demand would require to devote to agriculture an increasing fraction of available land. We also show that the validity of the conclusions...

This paper examines the sequence of optimal extraction of nonrenewable resources in the presence of multiple demands. We provide conditions under which extraction of a nonrenewable resource may be discontinuous over the course of its depletion.

The one-demand Hotelling model fails to explain the observed specialization of nonrenewable resources. We develop a model with multiple demands and resources to show that specialization of resources according to demand is driven by Ricardian comparative advantage while the order of resource use...

A well-known theorem by Herfindahl states that the low-cost nonrenewable resource must be exploited first. Consider resources that are differentiated only by their pollution content. For instance, both coal and natural gas are used to generate electricity, yet coal is more polluting. We show...

In the context of ever-increasing petroleum prices combined with concerns about climate change, timing of adoption and rate of diffusion of land-based fuels and backstop technologies for transportation use are examined in this paper. A global model of land allocation joined with a Hotelling...

Many regions such as the European Union and states in the U.S. have introduced mandates aimed at restricting carbon emissions. On the other hand, the stated goal of the Intergovernmental Panel on Climate Change (IPCC) which provides the science behind the current global climate negotiations is...

Nous analysons l’impact de deux politiques américaines sur la production et les échanges d’éthanol (biocarburants de première génération) et d’éthanol ligno-cellulosique (biocarburant de seconde génération) aux Etats-Unis et au Brésil ainsi que sur les émissions directes et...
