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 results for this model, by showing that the condensed wealth obeys a simple logistic equation in time. %[ 2018-10-10 %9 Text %~ Tufts Digital Library %W Institution
