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....

"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...

Authorities often lack information for efficient regulation of the commons. This paper derives a criterion comparing prices versus tradable quantities in terms of expected welfare, given uncertainty, optimal policy and endogenous cost structure. I show that one cannot determine which regulatory...

Climate physics predicts that the intensity of natural disasters will increase in the future due to climate change. One of the biggest challenges for economic modeling is the inherent uncertainty of climate events, which crucially affects consumption, investment, and abatement decisions. We...

Regulators often seek to promote the use of improved, cleaner technology when new investments occur; however, technology mandates are suspected of raising costs and delaying investment. We examine investment choices for electricity generation under a strict emissions rate performance standard...

This paper considers investments in cost-reducing technology in the context of contributions to climate protection. Contributions to mitigating climate change are analyzed in a two-period model where later contributions can be based on better information, but delaying the contribution to the...

We analyse effects of uncertain climate change and technological development on cost-effective abatement of nitrogen and phosphorus for a eutrophied sea. A dynamic model is developed which accounts for differences in the sea’s adjustment to the loads of the two nutrients, uncertainty in...

Non-point-source (NPS) pollution refers to a form of pollution in which neither the source nor the size of specific emissions can be observed or identified with sufficient accuracy. In NPS pollution the ambient concentration of pollutants associated with the individually unobserved emissions is...

Climate physics predicts that the intensity of natural disasters will increase in the future due to climate change.  One of the biggest challenges for economic modeling is the inherent uncertainty of climate events, which crucially affects consumption, investment, and abatement decisions.  We...
