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...

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...

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%)...

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...
