Large-scale environmental programs generally commit substantial societal resources, making the evaluation of their actual effects on the relevant outcomes imperative. As the example of the subsidization of energy-saving appliances illustrates, much of the applied environmental economics...

Political feasibility of emission trading systems may crucially depend on the free initial allocation of emission allowances to energy-intensive industries in order to ameliorate adverse production and employment effects. We investigate the potential trade-off between such compensation and...

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...

This paper deals with a special type of voluntary approach to protect the environment, for example, that we would like to term voluntary commitment. Its major characteristic is that it represents a unilateral declaration without a decisively active role of regulators. In other words, voluntary...

This paper advocates computable general equilibrium models as a methodological tool that is particularly suitable for measuring the impacts of policy interference on the three dimensions of sustainable development, i.e. environmental quality, economic performance (gross efficiency) and equity....

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...

We compare two options of integrating discrete working time choice of heterogenous households into a general equilibrium model. The first, known from the literature, produces household heterogeneity through a working time preference parameter. We contrast this with a model that directly...

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...

Germany has committed itself to reducing its carbon emissions by 25 percent in 2005 as compared to 1990 emission levels. To achieve this goal, the government has recently launched an environmental tax reform which entails a continuous increase in energy taxes in conjunction with a...

Our paper deals with the welfare and employment effects of green tax reforms. In the first part we develop a flexible, interactive simulation model which is accessible under http://brw.zew.de. Users can specify their own green tax reforms or emission quotas and quantify welfare and employment...
