We report numerical simulation results using a multiyear global multi country modeling framework which we use to assess the impacts of alternative emissions cuts which will likely come under consideration for the process to follow the December 2009 UNFCCC negotiation in Copenhagen. The...

In the CGE based policy modeling literature, especially recent literature on policy modeling for global climate change, nested CES production functions over multiple inputs have been widely used. Although lack of reliable estimates of substitution elasticities for nested structures has been...

Seminal work by Weitzman (1974) revealed prices are preferred to quantities when marginal benefits are relatively flat compared to marginal costs. We extend this comparison to indexed policies, where quantities are proportional to an index, such as output. We find that policy preferences hinge...

This paper discusses the role that trade can potentially play in both negotiating and operating a post Kyoto/post 2012 global climate policy regime. As an addition to the bargaining set for a global climate negotiation, trade in principle widens the range of jointly beneficial potential outcomes...

In a world where the prospects of a global agreement to control greenhouse gas emissions are bleak, the idea of using trade policy as an implicit regulation of foreign emission sources has gained many supporters in countries contemplating unilateral climate policies. Embodied carbon tariffs tax...

The UNFCCC process of negotiating multilateral carbon emissions reductions thus far has focused on approximately equiproportional cuts in annual carbon emissions by country along the lines of the Kyoto Protocol agreement. But now, with the objective of involving large developing countries such...

Does temperature affect economic performance? Has temperature always affected social welfare through its impact on physical and cognitive function? While many economic studies have explored the indirect links between climate and welfare (e.g. agriculture, conflict, sea-level rise), few address...

This research examines the climatic origins of the diffusion of Neolithic agriculture across countries and archaeological sites. The theory suggests that a foraging society s history of climatic shocks shaped the timing of its adoption of farming. Specifically, as long as climatic disturbances...

In the paper we discuss China's participation in both the 2009 Copenhagen negotiations on a post-Kyoto global climate change regime currently under way and out beyond Copenhagen in further negotiations likely to follow. China is now both the largest and most rapidly growing carbon emitter, and...

Regional liberalization sweeps the globe like wildfire while multilateral nude talks proceed at a glacial pace. Why are countries eager to liberalize regionally but reluctant to do so multilaterally? The answer of the GATT-is-dead school is that multilateralism is too cumbersome for contemporary...
