Multiple institutional affiliations occur when an academic belongs to more than one organisation. Recent research shows an increase in multiple affiliations, but evidence on roles and motivations is mainly anecdotal. We develop in this study a typology of co-affiliations which identifies four...

In the transition to decarbonized energy systems, Power-to-Gas (PtG) processes have the potential to connect the existing markets for electricity and hydrogen. Specifically, reversible PtG systems can convert electricity to hydrogen at times of ample power supply, yet they can also operate in...

This paper deals with a special type of voluntary approach to protect the environment, for example, that we would like to term voluntary commitment. Its major characteristic is that it represents a unilateral declaration without a decisively active role of regulators. In other words, voluntary...

In the context of climate protection policy it has been suggested that global CO2 emissions should be reduced significantly (contraction) and that per capita emissions should gradually be equalized across countries (convergence). This paper uses a dynamic multi-region computable general...

The Kyoto Protocol marks a break-through in global warming mitigation policies as it sets legally binding emissions targets for major emitting regions. However, realisation of the Protocol depends on the clarification of several issues one of which is the permissible scope of international...

We decompose the economic implications of the Kyoto Protocol at the cross-country level, splitting the total economic impact for each region into contributions from its own emission abatement policy and those from other regions. Our analysis which is based on a large-scale computable general...

The allocation of emissions entitlements across countries is the single most controversial issue in international climate policy. Extreme positions within the policy debate range from entitlement based on current emission patterns (CEP) to equal-per-capita (EPC) allocations.Convergence (COV)...

Environmental tax schemes in OECD countries often involve tax rates differentiated across industrial, commercial and household sectors. In this paper, we investigate four potentially important arguments for these deviations from uniform taxation: pre-existing tax distortions, domestic equity...

This paper empirically examines price formation in the European Union Emissions Trading Scheme (EU ETS). Our analysis shows that unexpected allocations of European Union Allowances (EUAs) lead to pronounced price reactions of the expected signs. Moreover, we find evidence that the adjustment of...

This policy report studies the effects of a sudden stop of natural gas imports from Russia on the German economy. The analysis focuses on the supply-side effects that arise when a gas shortage affects production in the gas-intensive manufacturing sectors, with a corresponding production...
