As tradeable permit programmes mature, two inter-related issues are becoming more critical in creating viable responses to a long-term, highly uncertain environmental problem such as climate change. First, we need to update policies in response to new information; and second, we need to design...

We analyse the optimal design of unilateral climate policy in an open economy where the government is committed to a target for reduction of domestic CO2 emissions but where it is also concerned about carbon leakage. We highlight the importance of distinguishing between leakage at the extensive...

Scientific expertise suggests that mitigating extreme world-wide climate change damages requires avoiding increases in the world mean temperature exceeding 2° Celsius. To achieve the two degree target, the cumulated global emissions must not exceed some limit, the so-called global carbon...

Climate change ranks high on the policy agenda of the European Union (EU) which considers itself as a leading force in the battle against anthropogenic climate change. The EU is committed to the objective of limiting the rise in global average temperature to no more than 2°C above...

We employ the footloose capital model to examine and compare how two countries decide on their emission permits non-cooperatively under domestic and international emissions trading in the presence of capital mobility. We find that even if two countries are symmetric and have the same carbon...

Energy system and power market models refrain from distinguishing between private and social discount rates. We devise a strategy to account for diverging private and social discount rates in intertemporal optimization frameworks, resulting in an optimal carbon tax above the marginal damage when...

Internalizing the global negative externality of carbon emissions requires flattening the extraction path of non-renewable fossil-fuel resources (= world carbon emissions). Following Eichner and Pethig (2011b) we set up a two-country two-period model in which one of the countries represents a...

Economic thought on climate policy as an instance of environmental regulation is strongly influenced by the principle of a uniform carbon price. Economists acknowledge that this principle breaks down in a second-best world with other distortions, such as taxes and market power in domestic and...
