There is a low but uncertain probability that climate change could trigger "mega-catastrophes," severe and at least partly irreversible adverse effects across broad regions. This paper first discusses the state of current knowledge and the defining characteristics of potential climate change...

This paper discusses short-run and long-run effects of "green stimulus" efforts, and compares these effects with "non-green" fiscal stimuli. Green stimulus is defined here as short-run fiscal stimuli that also serve a "green" or environmental purpose in a situation of "crisis" characterized by...

This paper explores two different conceptions of how an emerging climate regime might evolve to strengthen incentives for more vigorous cooperation in mitigating global climate change. One is the paradigm that has figured most prominently in negotiations to this point: the establishment of...

Since the onset of economic reforms in 1978, China has been remarkably successful in reducing the carbon dioxide intensities of gross domestic product and industrial production. Most analysts correctly attribute the rapid decline in the carbon dioxide intensity of industrial production to rising...

Energy intensity has declined significantly in four Chinese industries-pulp and paper; cement; iron and steel; and aluminum. While previous studies have identified technological change within an industry to be an important influence on energy intensity, few have examined how industry-specific...

This paper examines the possibility of environmental "development traps," or "brown poverty traps," caused by interactions between the impacts of climate change and increasing returns in the development of "clean-technology" sectors. A simple specification is used in which the economy can...
