| Abstract: | We develop a model with two types of electricity producers, fossil fuel utilities generating emissions, and suppliers of electricity from renewable resources such as wind energy. We account for the vertical structure of the wind-energy sector by considering wind-turbine producers engaged in learning by doing and selling their turbines to turbine operators. We show that in the absence of learning spillovers a first-best policy requires Pigouvian taxes only. We also study second-best optimal subsidies on electricity generated by wind power when (optimal) emission taxes are ruled out. We further investigate the impact of subsidies on prices, output, the number of firms, and environmental damage. It turns out that, in the case of purely private learning, secondbest optimal subsidies should only account for the environmental damage but are not necessary to spur learning. |

| Abstract: | In response to oil price rises and carbon emission concerns, policies promoting increased ethanol usage in gasoline blends are being implemented by many countries, including major energy users such as USA, EU and Japan. As a result, Brazil, as the largest ethanol producer and exporter in the world, can expect growing foreign demand for ethanol exports. Also, the introduction of flex-fuel vehicles in Brazil is causing domestic sales of ethanol to increase steadily. In this paper, we investigate the regional and industrial economic consequences of rapid growth in Brazilian ethanol consumption and exports. For this, we use a disaggregated multi-regional computable general equilibrium (CGE) model with energy industry detail. Our modelling emphasises a number of features of ethanol production in Brazil which we expect to be important in determining the adjustment of its regional economies to a substantial expansion in ethanol production. These include regional differences in ethanol and sugar production technologies, sugarcane harvesting methods and the elasticity of land supply to sugarcane production. |

| Abstract: | Currently informal and formal international negotiations on climate change take place in an intensive way since the Kyoto Protocol expires already in 2012. A post-Kyoto regulation to combat global warming is not yet stipulated. Due to rapidly increasing greenhouse gas emission levels, industrialized countries urge major polluters from the developing world like China and India to participate in a future agreement. Whether these developing countries will do so, depends on the prevailing incentives to participate in international climate protection efforts. This paper identifies ancillary benefits of climate policy to provide important incentives to attend a new international protocol and to positively affect the likelihood of accomplishing a post-Kyoto agreement which includes commitments of developing countries. |

| Abstract: | This paper investigates in how far equity preferences may matter for climate negotiations. For this purposes we conducted a simple experiment with people who have been involved in international climate policy. The experiment, which was run via the Internet, consisted of two simple non-strategic games suited to measure the parameters of inequity aversion in a Fehr and Schmidt (1999) utility function. We find that our participants show aversion against advantageous as well as disadvantageous inequity to a considerable amount. Moreover, the degree of inequity aversion is higher compared to that of students in the similar study of Dannenberg et al. (2007). Regarding the geographical variety in our sample, we cannot confirm significant differences in the degree of inequity aversion between different regions in the world, which is in line with previous findings from the experimental literature. This finding lends support to the hypothesis that equity preferences are "hard-wired" and not much influenced by socio-economic or cultural circumstances. |

| Abstract: | Ce article est issu de présentations et d'un débat menés lors d'un atelier de dialogue tenu le 27/04/2007 dans le cadre des projets de recherche SOCECO2 et METSTOR. Cet atelier de dialogue rassemblait des représentants des différents acteurs concernés par la problématique du captage et stockage du CO2 : scientifiques, industriels, pouvoirs publics, collectivités, associations, journalistes. L'objectif de cet atelier de dialogue était de réfléchir ensemble sur les conditions nécessaires au développement de cette nouvelle technologie. Le présent article reprend de manière simplifiée les principaux enjeux identifiés et les questions qu'il reste à résoudre. |
