Professor Markus Wagner was invited to present his work on trade and investment law at a joint research seminar between the Escuela de Direito of the school of law of the Fundação Getulio Varga and the Universidade Federal do Rio Grande do Sul in Sao Paulo, Brazil. His presentation was based on his forthcoming article titled "Policy Space in International Investment Law and International Trade Law," which compares the global trade and investment regimes. The paper, to be published in the University of Pennsylvania Journal of International Law, addresses the question to what extent states can claim policy space before international trade and investment tribunals. It finds that the experience of the WTO regime can serve as a useful blueprint for international investment law in situations in which states demand the ability to take policy decisions in public health or environmental matters. Professor Wagner teaches and writes in the areas of international law, constitutional law and comparative law. His recent scholarship has focused on the development of autonomous weaponry and its compatibility with international humanitarian law and various aspects of international economic law.
