Resource prices, and petroleum prices in particular, are volatile and difficult to predict, so government revenue in resource-producing regions is also uncertain and volatile. Adjusting government expenditure in response to these revenue movements involves economic, social and political costs....

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....

The declared long-term goal of the Intergovernmental Panel on Climate Change (IPCC) is the stabilization of carbon concentration in the atmosphere. In this paper we impose a carbon target concentration on a partial equilibrium model of the global energy sector. Specifically, we ask whether...

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

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 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...
