Spherical grand-canonical minority games with and without score discounting
Alex Bladon, Thomas Richardson, Tobias Galla
We present a spherical version of the grand-canonical minority game (GCMG), and solve its dynamics in the stationary state. The model displays several types of transitions between…
On the transition to efficiency in Minority Games
Tobias Galla, Andrea De Martino
The existence of a phase transition with diverging susceptibility in batch Minority Games (MGs) is the mark of informationally efficient regimes and is linked to the specifics of t…
Anomalous fluctuations in Minority Games and related multi-agent models of financial markets
Tobias Galla, Giancarlo Mosetti, Yi-Cheng Zhang
We review the recent approaches to modelling financial markets based on multi-agent systems. After a brief summary of the basic stylised facts observed in real-market time-series w…
