We consider the large range of estimated costs of meeting U.S. climate policy targets. Some of this range is due to different studies using different cost measures, and in principle such differences could be eliminated by more careful comparisons and greater transparency in studies that estimate...

Two computable general equilibrium models, one global and the other providing U.S. regional detail, are applied to analysis of the future of U.S. natural gas. The focus is on uncertainties including the scale and cost of gas resources, the costs of competing technologies, the pattern of...

We use an economy-wide model to estimate the impact of a representative climate policy on fuel prices and economic activity, and a partial equilibrium model of the aviation industry to estimate changes in aviation carbon dioxide emissions and operations. Between 2012 and 2050, with reference...
