I am a researcher in the Department for World Economy and Development Finance at the German Development Institute / Deutsches Institut für Entwicklungspolitik (DIE). I am mainly interested in the political economy of international investment with a special focus on developing and emerging countries. I am currently working on diffusion processes of international investment agreements. In the past I have worked on the effects of international investment agreements on international investment flows and the global impact of China, especially with regard to renewable energy and development cooperation. Please visit my DIE homepage for more information about publications and research projects. I also tweet at @ax_berger. And, of course, everything I say here is in my personal capacity.
