Stefan Mittnik (born November 29, 1954) is a German economist, currently holds the Chair of Financial Econometrics at the Ludwig Maximilian University of Munich. He is a fellow of the Center for Financial Studies and known for his work on financial market and financial risk modeling as well as macroeconometrics. He is also a co-founder of the German-British robo-advisor Scalable Capital.
Stefan Mittnik received a degree in business and engineering in 1981 from the Technical University Berlin in Germany. He continued his studies in the UK, earning an MA in development economics at the University of Sussex, and the U.S., earning his Ph.D. in economics and applied mathematics from Washington University in St. Louis in 1987.
After his graduate studies, Mittnik taught at Stony Brook University (1987-1994) and the University of Kiel in Germany (1994-2003). Since 2003 he is Professor of Financial Econometrics at the Ludwig Maximilian University of Munich (LMU Munich) in Germany where he currently also heads the Center for Quantitative Risk Analysis (CEQURA).
Mittnik was research director at the Ifo Institute for Economic Research, Fulbright Program Distinguished Scholar for German Studies at the Department of Economics at Washington University in St. Louis, Theodor Heuss Professor at The New School in New York, member of the Economics Review Board (Fachkollegium) of the Deutsche Forschungsgemeinschaft (German Science Foundation), member of the scientific advisory board of the Deutsche Bundesbank, and served on the editorial boards at a number of scientific journals. The German newspaper Frankfurter Allgemeine Zeitung listed him among the most influential German economists.
Mittnik's main research contributions have been in econometrics, time series analysis, finance, and risk management. Influenced by Benoit Mandelbrot, who was the first to criticize financial economists for relying on the normal distribution and ignoring fat tails in asset returns, he has developed methods for more realistic financial risk modeling, portfolio optimization and option pricing.
