We present a decomposition approach for integrated assessment modeling of climate policy based on a linear approximation of the climate system. Our objective is to demonstrate the usefulness of decomposition for integrated assessment models posed in a complementarity format. First, the...

This paper quantifies the macroeconomic impacts of the Clean Development Mechanism (CDM) under the Kyoto Protocol based on a computable general equilibrium (CGE) model of international trade and energy use. Employing project-based CDM supply data we assess the relative importance of transaction...

In the tax policy debate, differentiation of value-added taxes is often justified by distributional concerns. Our quantitative analysis for Germany indicates that such concerns are misplaced. We find that the abolition of VAT differentiation has only negligible redistributive effects. Instead,...

Energy markets and energy-intensive industries in all EU member states - especially in Germany - are subject to a diverse set of policies related to climate change. We analyse the potential efficiency losses from simultaneous application of emission taxes and emissions trading in qualitative and...

The formulation of market equilibrium problems as mixed complementarity problems (MCP)permits integration of bottom-up programming models of the energy system into top-down general equilibrium models of the overall economy. Despite the coherence and logical appeal of the integrated MCP approach,...

From 1 January 2005 onwards the European Union has launched the first large-scale international carbon emissions trading program. As the EU Emissions Trading Scheme (EU-ETS) covers only part of domestic carbon emissions, it implies a hybrid environmental regulation scheme: Each EU Member State...
