The quest for large and small fluctuations in minority games: financial and technological applications.
Dr Damien Challet, Nomura Centre for Quantitative Finance, Oxford

Abstract:
We first provide two alternative explanation on the relevance of Minority Games to financial markets. Then we build various models of financial markets on one of them, extending thebasic Minority Games to new realms. Under what conditions large price fluctuations arise in these models will be the central part of my talk.

Whereas one expects financial market models to produce large fluctuations, small fluctuations are a better outcome in a technological setting, for instance in the case of Internet routers trying to transmit efficiently packages. The second part of my talk proposes new stochastic strategies for the basic Minority Game that lead to minimal fluctuations.
