Prof. Dr. Achim Hagen

“My primary research focus is to enhance our understanding of the economic implications of domestic and international climate policy-making, particularly in relation to the political economy, transition risks, and the interaction with financial regulation. I aim to provide insights that can aid the transition towards a sustainable, carbon-neutral future.”
