Environmental concerns are becoming increasingly popular and nowadays find their place on the policy-makers agenda. The basic question that arises in these circumstances is whether environmental theses are consistent or not with the economic theory. Environmental issues must go through the...

Because of large economic and environmental asymmetries among world regions and the incentive to free ride, an international climate Regime with broad participation is hard to reach. Most of the so far proposed Regimes base on an allocation of emission rights that is to be perceived as fair....

We study the introduction of new technologies when their costs are subject to idiosyncratic uncertainty and can only be fully learned through individual experience. We set up a dynamic model of clean experience goods that replace old polluting consumption options and show how optimal regulation...

The patchwork of laws designed to control air pollution from U.S. power plants has been criticized from a variety of different perspectives. Business groups argue that the laws are too complex and burdensome to industry. Environmentalists maintain that power plant emissions need to be further...

"The so-called Environmental Sector produces technologies, products and services that prevent or reduce environmental damages. On the background of growing environmental problems such as climate protection this sector seems to be more and more important. Contrary to that, a theoretical model...

Eine strengere Klimapolitik in einem Teil der Welt kann zu Verschiebungen der komparativen Vorteile führen und damit zur Verlagerung der Herstellung besonders CO2-intensiver Güter in Länder mit laxer Klimapolitik. Die Analyse einer Datenbank mit den Footprints von 40 Ländern zeigt, dass die...

Electric and natural gas are the two major sources of energy for residents of Washington State. Several states have adopted a policy whereby utility companies decide on the choice of mixes of resources by incorporating cost effectiveness, conservation and externalities. Externalities could...

In this paper, we study a two-country dynamic setup with environmental externalities and potential model misspecification in relation to this public good. Under model uncertainty, robust policies help to correct the inefficiencies associated with free riding on public good provision, implying...

We consider environmental regulation in a context where firms invest in abatement technology under conditions of uncertainty about subsequent abatement cost, but can subsequently adjust output in the light of true marginal abatement cost. Where an emission tax is the only available instrument,...

How is the optimal level of Pigouvian taxation influenced by distributive concerns? With second-best instruments, a higher level of income redistribution calls for a lower level of Pigouvian taxation. More redistribution implies higher distortions from income taxation. Pigouvian tax revenues...
