Chair of Financial Econometrics & Asset Management
Research at the Chair of Financial Econometrics & Asset Management focuses on the development and estimation of econometric and financial models for banking network analysis, asset allocation, endowment management, hedge fund replication and risk management, with particular focus on operational risk.
- Asset Allocation
Our research interests are on the development of robust and reliable investment strategies, with a focus on regularization methods and volatility strategies, for index tracking and multiobjective optimization. Moreover, we develop optimization heuristics to deal with high dimensionality problems and real-world problems, typically characterized by non-convex objective functions and non-linear constraints.
- Risk Management
We focus on the development of quantitative risk-management tools to improve Value-at-Risk and tail-related risk measures in market, credit and operational risk. Moreover, tools that allow to get robust estimates and include dependence modelling are proposed to better deal with noisy data and explicitly capture dependences.
- Financial Networks
Our research aims at understanding the portfolio holdings and the interconnections among monetary financial institutions (MFI) in the financial markets, as well as to put forward regulatory suggestions to improve the resilience of the overall system. Current research projects, in cooperation with Deutsche Bundesbank, focus on identifying systemic relevant and highly concentrated MFI in the German bank equity market and on analyzing the risk and diversification of banks sovereign bond holdings both, at the level of single MFI and of the entire system.
