The volume contains papers presented at a conference "On the International Dimension of Environmental Policy". It deals with two issues: international environmental agreements; environmental policies in open economies. Both issues are hot topics. The debate on how to cope with global climate change has become increasingly heated and controversial, and the relationship between trade and the environment is on the WTO agenda. The book contains review papers in which leading scholars in the field summarise the state of the art and original research extending the state of the art. Most of the papers are theoretically oriented, but some papers also present empirical results, using new econometric methods and new data. The book contains material for those students of economics and researchers who wish to deepen their knowledge in the area of International Environmental Economics, but also for those who endeavour to break new ground in this important field of research.
