Exponential wealth distribution in a random market. A rigorous explanation (1103.5703v3)
Published 29 Mar 2011 in q-fin.GN, cs.MA, and nlin.AO
Abstract: In simulations of some economic gas-like models, the asymptotic regime shows an exponential wealth distribution, independently of the initial wealth distribution given to the system. The appearance of this statistical equilibrium for this type of gas-like models is explained in a rigorous analytical way.
