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 outcome of the December 2011 United Nations climate negotiations in Durban, South Africa, provides an important new opportunity to move toward an international climate policy architecture that is capable of delivering broad international participation and significant global CO2 emissions...

We assess the effect of ITC in a global growth model, DEMETER-1CCS, with learning by doing where energy savings, an energy transition, and carbon capturing and sequestration (CCS) are the main options for emissions reductions. The model accounts for technology based on learning by doing embodied...

There is growing impetus for a domestic U.S. climate policy that can provide meaningful reductions in emissions of CO2 and other greenhouse gases. I describe and analyze an up- stream, economy-wide CO2 cap-and-trade system which implements a gradual trajectory of emissions reductions (with...

There is growing impetus for a domestic U.S. climate policy that can provide meaningful reductions in emissions of CO2 and other greenhouse gases. In this article, I propose and analyze a scientifically sound, economically rational, and politically feasible approach for the United States to...
