What should be the West's top priority for climate-change policy? This article is a revised and updated version of my talk to the Potsdam Global Sustainability Symposium (which drafted the Potsdam Declaration presented to the 2007 UN Climate Change Conference in Bali).

We design a global refunding scheme as a new international approach to address climate change. A global refunding system allows each country to set its carbon emission tax, while aggregate tax revenues are partially refunded to member countries in proportion to the relative emission reductions...

We propose a blueprint for an international emission permit market such as the EU trading scheme. Each country decides on the amount of permits it wants to offer. A fraction of these permits is grandfathered, the remainder is auctioned. Revenues from the auction are collected in a global fund...

We suggest a development-compatible refunding system designed to mitigate climate change. Industrial countries pay an initial fee into a global fund. Each country chooses its national carbon tax. Part of the global fund is refunded to developing and industrial countries, in proportion to the...

This paper examines future energy and emissions scenarios in China generated by the Integrated Assessment Model WITCH. A Business-as-Usual scenario is compared with five scenarios in which Greenhouse Gases emissions are taxed, at different levels. The elasticity of China’s emissions is...

We study the political economy of social insurance in a world where individuals differ in both income and risk. Social insurance is financed through distortionary taxation and redistributes across income and risk. Individuals vote on social insurance that they can complement with insurance...

We derive conditions of individual preferences and technology that give rise to a negative correlation between income inequality and environmental protection. We present a class of models (which captures a static model as well as an overlapping-generations model) in which individuals differ in...

We analyse how, in representative democracies, income distribution influences the stringency of environmental policy and economic growth. Individuals (who differ in abilities) live for two periods, working when young and owning capital when old. Externalities are caused by a polluting factor....

The analysis provides a new explanation for two widespread problems concerning European unemployment policy: the disappointingly small effect of many past reform measures on unemployment; and the political difficulties in implementing more extensive reform programmes. We argue that the heart of...

This paper is the concluding chapter of Rights, Rents and Fairness: Allocation in the European Emissions Trading Scheme, edited by the co-authors and forthcoming from Cambridge University Press. The main objective of this paper is to distill the lessons and general principles to be learnt from...
