American politicians often take it for granted that national security would be enhanced by accelerating domestic oil production, through policies such as subsidies, tax advantages, opening up federal lands for drilling at artificially low charges, and relaxing environmental regulation. This note...

Gasoline taxes can be employed to correct externalities associated with automobile use, to reduce dependency on foreign oil, and to raise government revenue. Our understanding of the optimal gasoline tax and the efficacy of existing taxes is largely based on empirical analysis of consumer...

Emissions of greenhouse gases linked with global climate change are affected by diverse aspects of economic activity, including individual consumption, business investment, and government spending. An effective climate policy will have to modify the decision calculus for these activities in the...

The BP Deepwater Horizon oil spill highlighted the glaring weakness in the current liability and regulatory regime for oil spills and for environmental catastrophes more broadly. This article proposes a new liability structure for deep sea oil drilling and for catastrophic risks generally. It...

Cap-and-trade systems have emerged as the preferred national and regional instrument for reducing emissions of greenhouse gases throughout the industrialized world, and the Clean Development Mechanism--an international emission-reduction-credit system--has developed a substantial constituency,...
