Social Transition Spectrum in Constant Sum 2x2 Games with Human Subjects

Abstract

In game, with the individual interactions, the social state is changing stochastically and governed by Nash Equilibrium in the strategy space. With the method from the physics of nonequlibrium steady state (NESS) and the data from experimental economics treatments (EET), we obtain the social transition spectrums and from which, the kink phenomena and the fluctuation theorem predictions in NESS are supported. The data comes from the fixed paired 2-person constant sum 2x2 games with unique mixed strategy Nash equilibrium (MSNE). These findings demonstrate the new experimetric for social dynamics, meanwhile, an indifference within social and physical systems.
