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...

We discuss a strategy for investigating the impacts of climate change on Earth’s physical, biological and human resources and links to their socio-economic consequences. As examples, we consider effects on agriculture and human health. Progress requires a careful understanding of the chain of...

First steps toward a broad climate agreement, such as the Kyoto Protocol, have focused on less than global geographic coverage. We consider instead a policy that is less comprehensive in term of greenhouse gases (GHGs), including only the non-CO2 GHGs, but is geographically comprehensive....

In 2003 Japan proposed a Climate Change Tax to reduce its CO<Subscript>2</Subscript> emissions to the level required by the Kyoto Protocol. If implemented, the tax would be levied on fossil fuel use and the revenue distributed to encourage the purchase of energy efficient equipment. Analysis using the MIT Emissions...</subscript>

*Chapter 8 of the forthcoming book "Economic Analysis of Land Use in Global Climate Change Policy," edited by Thomas W. Hertel, Steven Rose, and Richard S.J. Tol. We describe an approach for incorporating biomass energy production and competition for land into the MIT Emissions Prediction and...

This paper estimates the value of international emissions trading, focusing on a here-to-fore neglected component; its value as a hedge against uncertainty. Much analysis has been done of the Kyoto Protocol and other potential international greenhouse gas mitigation policies comparing the costs...

In this paper we investigate the potential production and implications of a global biofuels industry. We develop alternative approaches to consistently introduce land as an economic factor input and in physical terms into a computable general equilibrium framework. The approach allows us to...
