In the standard setting a system of tradable permits is effective and cost-efficient in attaining the policy objective of pollution reduction. This outcome is challenged in case of a tradable permit system in a federal system/constitution with individual states having discretionary power...

Cap and trade mechanisms enjoy increasing importance in environmental legislation worldwide. The most prominent example is probably given by the European Union Emission Trading System (EU ETS) designed to limit emissions of greenhouse gases, several other countries already have or are planning...

Given that the carbon price in the EU Emissions Trading System is only around 5€/tCO2 while consensus about a more stringent EU climate policy is very unlikely in the near future, we explore the potential scope and optimal design of additional national climate policies in the current EU policy...

Climate change economics mostly neglects sizeable interactions of carbon pricing with other fiscal policy instruments. Conversely, public finance typically overlooks the effects of future decarbonization efforts when devising instruments for the major goals of fiscal policy. We argue that such a...

In 2005, an EU-wide emissions trading scheme covering major CO2 producing sites shall come into power. The key objective of the trading scheme is to promote cost-efficiency of carbon reduction within the EU. We identify policy-relevant tradeoffs between overall efficiency, compensation and...

In the standard setting a system of tradable permits is effective and cost-efficient in attaining the policy objective of pollution reduction. This outcome is challenged in case of a tradable permit system in a federal system/constitution with individual states having discretionary power...

This essay revisits the question of instrument choice for the regulation of externalities in the context of climate change. The central point is that the Pigouvian prescription to equate marginal control costs with the expected marginal benefits of damage reduction should guide the design of...

While emissions trading schemes are developed by nations to mitigate their greenhouse gas emissions, behavioural studies have shown that the political and public acceptability of these market-based instruments depends on the way the associated revenues are used. One option the general public...

The social cost of carbon is the central economic measure for aggregate climate change damages and functions as a metric for optimal carbon prices. Previous literature shows that inequality significantly influences the level of the social cost of carbon, but mostly neglects a major source of...

The good intentions of COP21 are to be reached by novel climate policy instrumentation, beyond what has been developed till now. For the long term two fundamentally different strategies emerge, each leading to a set of instruments fit for the challenging task in principle. The first has a...
