Official description:
This workshop brings together leading experts from mathematics, economics, operations research and engineering departments to discuss recent developments in the theory of many player games and their applications to finance and engineering. The workshop follows up on series of similar events in a recent ZiF Research Group held at Bielefeld University (ZiF - Robust Finance) where the impact of uncertainty and ambiguity for optimal economic decision making were explored. 

The workshop was held on August 29 - August 31, 2022 at the Humboldt University Berlin. It is sponsored by Springer publisher, the Collaborative Research Center CRC 1283 at Bielefeld University, the Berlin-Oxford International Research Training Group IRTG 2544, and the Transregio Collaborative Research Center TRCRC 190 at Humboldt University and LMU Munich. The workshop is jointly organized by the Humboldt University at Berlin and the Center for Mathematical Economics at Bielefeld University.

Online talk by Manuel Förster at Paris 1 Panthéon-Sorbonne

Veröffentlicht am 17. Mai 2021
On May 20, Manuel Förster gives an online talk with the title "Strategic transmission of imperfect information: Why revealing evidence (without proof) is difficult" at the University Paris 1 Panthéon-Sorbonne.
Abstract: In our cheap-talk setting, an expert privately observes multiple binary signals, her soft evidence, about a continuous state of the world and then communicates with a decision-maker. While direct transmission of evidence entails communicating details on and potentially revealing each signal, indirect transmission of evidence entails communicating a summary statistics of her evidence. We first establish that fully informative equilibria exist if the conflict of interest is small. Otherwise, direct transmission of evidence is impossible, as neglecting one part of the soft evidence in the communication necessarily induces incentives to manipulate the report on the other part. On the contrary, indirect transmission of evidence remains partially informative for intermediate conflicts of interest. Finally, we introduce the possibility of verification. We show that, if the costs of verification are low, the expert can fully reveal her evidence regardless of the conflict of interest.
