英文摘要:
The addition of wealth-attained advantage (WAA) to the Yard-Sale Model (YSM) of asset exchange has been demonstrated to induce wealth condensation. In a model of WAA for which the bias is a continuous function of the wealth difference of the transacting agents, the condensation was shown to arise 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 logistic equation in time.

中文摘要:
已证明,将财富获得优势(WAA)添加到资产交换的场内销售模型(YSM)中会导致财富凝聚。在一个WAA模型中,偏差是交易主体财富差异的连续函数,结果表明,凝聚是从二阶相变到共存状态产生的。本文通过证明凝聚财富在时间上服从logistic方程,给出了该模型的第一个与时间相关的分析结果。
