The addition of wealth-attained advantage (WAA) to the Yard-Sale Model (YSM) of asset exchange has been demonstrated to induce wealth condensation. In models of WAA for which the bias is a continuous function of the wealth difference of the transacting agents, the condensation arises from a second-order phase transition to a coexistence regime. In this paper, we present the first analytic time-dependent ... read moreresults for this model, by showing that the condensed wealth obeys a simple logistic equation in time.read less
