Cap and trade mechanisms enjoy increasing importance in environmental legislations worldwide. One of the important aspects of designing cap and trade mechanisms is the possibility of authorities to grant emission permits for free. Unlike analyzed in the seminal contributions on cap and trade...

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...

Political feasibility of emission trading systems may crucially depend on the free initial allocation of emission allowances to energy-intensive industries in order to ameliorate adverse production and employment effects. We investigate the potential trade-off between such compensation and...

There are different views with respect to the treatment of tradeable permits for greenhouse gases in cost-benefit analysis. This note aims at illustrating numerically within a simple general equilibrium model how to treat tradeable permits in economic evaluations of projects. The note looks at a...

There are conflicting views on how to handle permits for greenhouse gases in cost-benefit analysis. This paper aims at clarifying within a simple general equilibrium model how to treat different kinds of trade-able permits in economic evaluations of projects. Within a framework that reminds of...

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...

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...
