The researchers in the department International Economic Policy, Financial and Real Estate Markets deal with current issues of international economic and monetary policy, examine the economic significance of financial markets and real estate markets, and address questions of European integration and international trade policy. The researchers get involved in economic policy debates, be it the discussion on rent control and housing shortages, on the future of the WTO and how to deal with China, or on the ECB's interest rate policy and the Stability and Growth Pact.
