From Minority Games to real markets
D. Challet, A. Chessa, M. Marsili +1
We address the question of market efficiency using the Minority Game (MG) model. First we show that removing unrealistic features of the MG leads to models which reproduce a scalin…
Replica symmetry breaking in the minority game
Andrea De Martino, Matteo Marsili
We extend and complete recent work concerning the analytic solution of the minority game. Nash equilibria (NE) of the game have been found to be related to the ground states of a d…
Trading behavior and excess volatility in toy markets
M. Marsili, D. Challet
We study the relation between the trading behavior of agents and volatility in toy markets of adaptive inductively rational agents. We show that excess volatility, in such simplifi…
Data clustering and noise undressing of correlation matrices
M. Marsili
We discuss a new approach to data clustering. We find that maximum likelyhood leads naturally to an Hamiltonian of Potts variables which depends on the correlation matrix and whose…
Nonequilibrium phase transition in a model for social influence
Claudio Castellano, Matteo Marsili, Alessandro Vespignani
We present extensive numerical simulations of the Axelrod's model for social influence, aimed at understanding the formation of cultural domains. This is a nonequilibrium model wit…
