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 policy instruments for emissions reductions will be an integral part of a Post Kyoto Climate Regime. In this paper we compare a harmonized international carbon tax to a cap and trade system with different allocation rules for the emission caps. The caps are based either on the requirement...

In this paper we consider the impact of vertical integration on a retailer's choices of product variety and specific, brand-supporting investment. In an incomplete contract environment, vertical merger encourages investment in integrated supply, and foreclosure of non-integrated manufacturers....

Hybrid governance structures between markets and hierarchies in many industries, e.g., in energy and telecommunications, challenge antitrust and regulation policy. The paper focuses on the theoretical and methodological basis provided by the New Institutional Economics (NIE) for analyzing the...

The paper starts with a description of major reforms of EU policy in the network industries. Based on the normative economics of regulation, it then points out generic information and transaction cost problems of regulatory policy making. An appropriate allocation of regulatory competencies may...

A digressive tax like a variable rate sales tax or a tax on price gives firms an incentive for expanding output. Thus, unlike unit and ad valorem taxes which amplify the harm from monopoly, a digressive tax lessens the harm. We analyse a tax on price with respect to efficiency and practical...

Governments may draft contracts with market agents for allocating subsidies and pursuing specific policy goals. Contract enforcement via binding commitments is difficult, however, when exogenous (environmental) and endogenous (behavioural) risks interact. Analyzing the old debt compromise in...

The Fukushima Daiichi accident in Japan in March 2011 caused a fundamental change in Germany's energy policy which led to the immediate shut down of nearly half of its nuclear power plants. This paper uses data from Germany's largest internet platform for real estate to investigate the effect of...

The number of studies published focusing on people’s preferences for green electricity has increased steadily, making it more and more difficult to identify key explanatory factors that determine people’s willingness-to-pay (WTP). Based on results of a meta-regression our results indicate...
