Optimal policy design should maximize environmental benefits and minimize negative impacts of the environmental tax reform (ETR) on economy and society. Both researchers and policy makers are interested in potential impacts of ETR implementation as perceived by the relevant stakeholders....

This paper investigates the economic impacts of environmental tax reforms designed to reach given emission reduction targets for the German economy. Our focus is on the efficiency and employment implications of alternative schemes for emission tax differentiation between the production sector...

We develop an endogenous growth model with capital, labor and energy as production factors and three productivity variables that measure accumulated innovations for energy production, energy savings, and neutral growth. All markets are complete and perfect, except for research, for which we...

We develop an economic model for fossil-fuel and carbon-free energy supply and demand with capital and labor as production factors, and endogenous technological change through learning by research and learning by doing. We use the model to study inter-temporally efficient carbon taxes for...

We develop a partial one-sector model with capital, natural resources, and labor as production factors, and endogenous technological change through research. Production exhibits increasing returns to scale. We compare the response of output and resource use to a change in resource prices with...

There is a tendency among policy-makers and industry lobbyists toward "specific", "relative" or "output-based" quotas, i.e., freely distributed to firms proportionally to their output. With a stochastic analytical model, we demonstrate that relative quotas are dominated either by absolute quotas...

We develop an economic partial equilibrium model for energy supply and demand with capital and labor as production factors, and endogenous technological change through learning by research and learning by doing. Our model reproduces the learning curve typical for (bottom-up) energy system...

Environmental taxation very often comprises special provisions for parts of the business sector in order to attenuate effects on competitiveness of emissionintensive activities. This paper discusses motives, alternative designs and criteria for the evaluation of such safeguards and analyzes if...

In den vergangenen Jahren haben sich CO2-Emissionen als maßgebliche Bemessungsgrundlage von Kfz-Steuern in den meisten europäischen Ländern durchgesetzt. Auch Deutschland hat ab Juli 2009 die Pkw-Steuer für Neufahrzeuge an dieser Größe orientiert, um klimapolitische Ziele zu verfolgen. Das...
