Es wird aufgezeigt, wie sich der umweltpolitische Lenkungsmechanismus einer Kohlendioxydabgabe in effezienter Weise auf eine Reihe weiterer Treibhausgase ausdehnen läßt (Methan, Distickstoffoxyd, Fluorchlorkohlenwasserstoffe). Mit Hilfe eines Optimierungsmodells werden die theoretischen...

Conventional analysis of the economics of environmental policy usually claims that emission taxes induce a stronger incentive for an improvement in pollution abatement technologies compared to emission standards. In contrast, recent empirical studies reveal that there is no systematic...

The probability that an agent takes a certain action or a certain event occurs depends often on the actions taken by some agents. If this probability depends not only on current actions but on the sum of all past actions, these stock-dependent risks imply an intertemporal effect. In the present...

We incorporate the process of policy diffusion (i.e. the uncoordinated dissemination of policies among countries) into a probabilistic two-country-model of strategic environmental policy. Contrary to the usual setting with simultaneous decision making we consider the impact of sequential...
