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...

We study how environmental regulation in the form of a cap on aggregate emissions from a fossil fuel (e.g., coal) interacts with the arrival of a clean substitute (e.g., solar energy). The cost of the substitute is assumed to decrease with cumulative use because of learning-by-doing. We show...

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...

In this paper, we show that the potential for endogenous technological change in alternative energy sources may alter the behaviour of resource-owning firms. When technological progress in an alternative energy source can occur through learning-by-doing, resource owners face competing incentives...

Biofuels have received a lot of attention as a substitute for gasoline in transportation. They have also been blamed for recent increases in food prices. Both the United States and the European Union have adopted mandatory blending policies that require a sharp increase in the use of biofuels....

More than 40% of US corn is now used to produce biofuels, which are used as substitutes for gasoline in transportation. Biofuels have been blamed universally for recent increases in world food prices. Many studies have shown that these energy mandates in the US and EU may have a large (30-60%)...
