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...

Many countries are promoting biofuels as a substitute for scarce oil. This paper develops a dynamic model of land allocation between food and energy and shows how the model can be calibrated using standard optimization techniques. Some possible implications of the trade-offs between food and...

More than 40% of US grain 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%)...

More than 40 percent of US corn is now used to produce biofuels, which are used as substitutes for gasoline in transportation. Biofuels have been blamed universally for past increases in world food prices, and many studies have shown that energy mandates in the United States and European Union...

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

Can nuclear power, which is carbon free, solve the global warming problem? It is a tough sell in the advanced countries, but many new nuclear power plants are under construction in the developing world. We develop an empirical Hotelling model that accounts for the limited stock of uranium,...

The Kyoto Protocol is now a legally binding treaty signed by 141 nations, although not by major polluting nations such as the United States, China and India. Can nuclear power, which is carbon free, save Kyoto and solve the global warming problem? Nuclear energy is a tough sell in the developed...
