The current financial crisis is characterized by a massive deterioration of liquidity and trust among participants. This can be witnessed especially in the interbank markets, which after the Lehman Brother’s debacle essentially completely dried up. How can markets be made functioning again? How can trust be restored? How can the financial system be repaired? What should be the pillars of a new financial order? These are the main issues the project attempts to address. Three main themes will be pursued:

1. How does market information affect market liquidity and the informational content of market prices? How can such prices be useful for regulatory policies. For example,  which role should they play for accounting purposes?

2. How should securities be priced, when arbitrage is impaired, e.g. for lack of liquidity?

3. How do behavioural features such as ambiguity aversion and loss aversion affect market prices and market liquidity?

Ultimately, the insights from basic research about individual behaviour and the reactions of the marekt system will provide guidance into the basic pillars a new financial order might be based upon.
