In this seminar, we study international climate policy in a globalized world. We identify threats to the effectiveness of international climate policy initiatives such as the Paris Agreement or the EU Emission Trading Scheme, learn how climate policy, international trade, and trade policy interact and which measures can be taken to avoid free-riding or the relocation of emission-intensive industries. The course will cover recent theoretical and quantitative research papers in this area and students will reproduce the arguments and critically assess the insights from these state-of-the-art contributions in the literature.
