This paper has three messages mainly, which are observed in a simple model of climate change, international trade and regional adaptation. First, trade can be viewed as a kind of adaptation to climate change and variability, as trade can help to reduce direct impacts of global climate change on a region’s welfare. In particular, the less affected and the(More)
Mitigation and adaptation are the most important strategies in combating global climate change. It is expected that in a post Kyoto world industrialized countries have to engage in greenhouse gas abatement, and to support developing countries in adapting to climate change. Within the framework of a non-cooperative Nash game we analyze, whether funding(More)
This paper discusses the interplay between the choice of the discount rate, greenhouse gas mitigation and endogenous technological change. Neglecting the issue of uncertainty it is shown that the green golden rule stock of atmospheric carbon is uniquely determined, but is not affected by technological change. More general it is shown analytically within the(More)
This paper analyses banking and borrowing of carbon emission rights within the framework of a simple, integrated assessment model. Breaking the world economy in just two regions it will be shown: (1) Increasing when-flexibility in greenhouse gas abatement through banking and borrowing of carbon emission permits has a positive effect on welfare for regions(More)
This paper analyses the interplay between international trade, regional adaptation and Northto-South transfers for funding adaptation within the framework of a dynamic computable general equilibrium model, where impacts of climate change depend on changes in precipitation and temperature. If all regions, even the least developed ones, own the necessary(More)
Within the framework of a dynamic Computable General Equilibrium model this paper analyses the impact of trade restrictions on regional rates of return on capital, marginal costs of abatement and optimal climate policy. It will be shown that regional differences both in marginal costs of abatement and in the marginal productivity of capital are driven by(More)
