In a Ramsey policy regime, heterogeneity in beliefs about the potential costs of climate change is shown to produce policy ambiguities that alter carbon prices and taxation. Three sources of ambiguity are considered: (i) the private sector is skeptical, with beliefs that are unknown to the...

This paper contributes to the empirical literature on the relationship between environmental regulation and firm behavior. In particular, we ask whether and how strongly investment decisions of firms respond to stringency in environmental regulation. Environmental stringency is measured as (i)...

Mit der Einführung des europäischen Emissionshandelssystems kommt es zwangs-läufig zu einer Überschneidung der Regelungsbereiche mit der in Deutschland be-reits existierenden Ökosteuer. In diesem Artikel wird diskutiert, inwieweit durch die direkte und indirekte Interaktion beider...

In this paper we study political-economy determinants of the differentiation of environmental taxes between sectors. Using a common-agency model, we provide predictions on tax differentiation which are then tested using data from the German Ecological Tax Reform. As the reform is revenue neutral...

The combination of emissions trading and emissions taxes is usually rejected as redundant or inefficient. This conclusion is based on the restrictive assumption that both policies are exclusively meant to control pollution. However, particularly taxes may pursue a variety of other policy...

Economists generally hold that environmental regulations impose constraints on the production possibilities set and are therefore potentially harmful to economic growth. In recent years, however, it has been recognized that environmental regulation can enhance the prospects for growth if...

This paper deals with an assessment of the economic costs of environmental policies in the Netherlands, using a dynamic Applied General Equilibrium model with bottom-up information on abatement techniques. Empirical abatement cost curves are used to determine substitution possibilities between...

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 consider a simple dynamic model of environmental taxation that exhibits time inconsistency. There are two categories of firms, Believers, who take the tax announcements made by the Regulator to face value, and Non-Believers, who perfectly anticipate the Regulator's decisions, albeit at a...

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...
