Duality in an asset exchange model for wealth distribution

Abstract

Asset exchange models are agent-based economic models with binary transactions. Previous investigations have augmented these models with mechanisms for wealth redistribution, quantified by a parameter χ, and for trading bias favoring wealthier agents, quantified by a parameter ζ. By deriving and analyzing a Fokker–Planck equation for a particular asset exchange model thus augmented, it has been shown that it exhibits a second-order phase transition at ζ∕χ=1, between regimes with and without partial wealth condensation. In the “subcritical” regime with ζ∕χ<1, all of the wealth is classically distributed; in the “supercritical” regime with ζ∕χ>1, a fraction 1−χ∕ζ of the wealth is condensed. Intuitively, one may associate the supercritical, wealth-condensed regime as reflecting the presence of “oligarchy,” by which we mean that an infinitesimal fraction of the total agents hold a finite fraction of the total wealth in the continuum limit.
