A small open economy produces a consumer good, green and black energy, and imports fossil fuel at an uncertain price. Unregulated competitive markets are shown to be inefficient. The implied market failures are due to the agents' attitudes toward risk, to risk shifting and the uniform price for...

We analyse optimal environmental policies in a market that is vertically differentiated in terms of the energy efficiency of products. Considering energy taxes, subsidies to firms for investment in more eco-friendly products, and product standards, we are particularly interested in how...

Taxing internationally mobile factors of production has been dismissed as an inefficient means of raising tax revenue. This paper addresses the question of whether it is efficient to tax capital at source when labor markets and the taxation of lumpsum income suffer from imperfections. Four...

The purpose of this paper is to extend the dynamic resource allocation problem by including stock externalities like accumulated CO2 and SO2 emissions as well as flow externalities like waste of energy or pollutants which can be abated (SO2). The objective is to examine how the evolution of...

Zwischen 2002 und 2007 verabschiedete die Bundesregierung die Nationale Nachhaltigkeitsstrategie und das Integrierte Energie- und Klimaprogramm. Beide Programme enthalten klare energie- und klimapolitische Zielsetzungen: So sollen die Treibhausgasemissionen bis zum Jahr 2020 um 40% gesenkt...

Between 2002 and 2007, Germany introduced its National Strategy for Sustainable Development and its Integrated Climate Protection Program, which both defined clear energy and climate-related objectives, setting an emissions reduction trajectory of 40% below the 1990 level by 2020. This spurred...

We consider a global externality of resource use, with the example of greenhouse gas emissions from fossil fuels. A region concerned about climate change may reduce its fuel deposit offer, reduce fuel consumption, and withdraw investments into global fuel extraction. We study leakage rates and...

This paper first reviews the conceptual case for, and appropriate design of, fiscal policies to address major externalities associated with energy use-global warming, local air pollution, and various side effects (e.g., congestion) from motor vehicles. Techniques for (roughly) estimating the...
