2024 DGVFM-Workshop for Young Mathematicians

Professor Dr. An Chen (Ulm University) co-organized the Workshop for Young Mathematicians on Nov 13-15, 2024 in Castle Reisensburg for German Society for Insurance and Financial Mathematics (DGVFM). Eight renowed speakers from academia and practice have provided extremely interesting up-to-date insights in various fields of actuarial science: Prof. Dr. Hansjörg Albrecher (Université de Lausanne), Prof. Dr. Jan-Philipp Schmidt (TH Köln),  Prof. Dr. Manuel Rach (Universität St. Gallen),  Prof. Dr. Luitgard Veraart (London School of Economics and Political Science), Dr. Dorothee Riemann (Gen Re),  Constantin Papaspyratos (Bund der Versicherten), Prof. Dr. An Chen (Universität Ulm) and Prof. Dr. Jörn Saß (RPTU Kaiserslautern-Landau). The topics vary from reinsurance and how to price for a catastrophe cover as well as the challenges of climate change for insurers, dynamic pricing approaches, valuation and design of sustainability-linked bonds, compression of insurance portfolios, to issues related to supervisory and contractual aspects.  Around 30 master, bachelor and Ph.D students attended the workshop and enjoyed fruitful discussions with the speakers and the cozy atmosphere of the workshop.

SCOR Actuarial Award 2024

6th Fudan-Ulm Symposium on Finance and Insurance

The 6th Fudan-Ulm Symposium on Finance and Insurance took place at the School of Economics, Fudan University, from September 5 to 6, 2024. Co-hosted by Fudan University’s School of Economics and Ulm University’s Faculty of Mathematics and Economics, with support from the International Finance and Insurance Association (IFIA), this event showcased cutting-edge research across a range of topics including asset allocation, risk management, insurance product design, and more.

This year's symposium was a significant event for the insurance discipline in Fudan and Ulm, attracting participants from various universities and industry professionals, and fostering lively discussions and future collaboration. We look forward to the next edition at Ulm University!

FADeRiS 2024 @Ulm

This year's Foundations and Applications of Decentralized Risk Sharing (FADeRiS) conference took place over three days from May 27-29 at Universität Ulm at the beautiful 10th century historic Reisensburg Castle - organized by An Chen (Ulm University) and Peter Hieber (University of Lausanne - HEC Lausanne).

FADeRiS is a conference series dedicated to the theory and practical application of decentralized risk-sharing schemes. Decentralized risk-sharing refers to risk-sharing mechanisms under which the participants in a pool decide to share their risks among themselves, as opposed to classical insurance where an insurance provider takes relevant risks. Examples include peer-to-peer (P2P) insurance, pooled annuity funds or tontines.

Many thanks to all participants for this wonderful conference!

Further information about the conference can be found in the expandable text field.

Detailed information

The first day of the conference featured inspiring presentations on user-friendly metrics for annuitants and the ethics of mortality risk sharing. The second day focused on various aspects of risk sharing and risk management. Morning sessions covered topics such as efficient uncertainty sharing, risk under ambiguity, and the impact of climate change on natural catastrophe risk pooling. In the afternoon, sessions explored the nuances of tontines, including their financial guarantees and actuarial fairness, as well as the impact of mortality dynamics on mutual risk sharing. The third day concluded the conference with presentations on economics and mathematics of risk sharing, as well as belief-neutral Pareto efficiency and robust peer-to-peer risk sharing

In addition to cutting-edge scientific presentations, there were many opportunities for scientific exchange and networking.

The full program, more information about this year's conference and also about the first edition - initiated by Jan Dhaene, Mario Ghossoub, and Michel Denuit - which took place at KU Leuven, can be found here:

DGVFM Weiterbildungstag

On March 5th 2024 the 15th DGVFM CPD Day took place. The workshop was hosted by SV SparkassenVersicherung in Stuttgart and organized by the HAW-Ausschuss DGVFM (lead: Prof. Dr. An Chen (Universität Ulm) and Prof. Dr. Stefan Weber (Leibniz Universität Hannover)) and Dr. Michael Kochanski (appointed actuary SV SparkassenVersicherung) with the topic "Financial Planning for Retirement: Analyzing Costs and Strategies".

Participants were able to gain insights from research and practice through the following presentations:

  • Inroduction, Prof. Dr. An Chen (Universität Ulm) and Dr. Michael Kochanski (SV SparkassenVersicherung)
  • Value for Money, Dr. Tobias Rieck (Allianz Life)
  • Financial Literacy and Retirement Planning, Prof. Dr. Tabea Bucher-Koenen (Universität Mannheim)
  • Retirement planning - what should it cost or what must it achieve?, Prof. Dr. Ralf Korn (Rheinland-Pfälzische Technische Universität Kaiserslautern-Landau (RPTU))

The recordings of the presentations will be available soon via actuview: Link
Many thanks to the speakers for their excellent presentations and to SV SparkassenVersicherung for being a great host!

Chris Daykin Prize 2023 for the best pension related paper

The International Actuarial Association (IAA) has awarded the Chris Daykin Prize 2023 for the best pension relatd paper in the ASTIN Bulletin to Prof. Dr. An Chen and former IVW PhD student Dr. Fangyuan Zhang (joint work with Prof. Dr. Motonobu Kanagawa, EURECOM). The ASTIN Bulletin is one of the most prestigious journals in the field of actuarial science.

In their paper, they analyze a collective defined contribution pension system with multiple overlapping generations. They solve a mathematically complex Bayesian optimization problem and analyze for which persons and under which conditions the welfare can be improved by intergenerational risk sharing. In particular, the results show that intergenerational risk sharing in volatile financial markets leads to an increase in welfare for risk-averse individuals. The analyses are highly relevant for both research and practice, e.g. for pension funds.

Congratulations!
