英文摘要：
  A dynamic agent model is introduced with an annual random wealth multiplicative process followed by taxes paid according to a linear wealth-dependent tax rate. If poor agents pay higher tax rates than rich agents, eventually all wealth becomes concentrated in the hands of a single agent. By contrast, if poor agents are subject to lower tax rates, the economic collective process continues forever.

中文摘要：
引入了一个动态代理模型，该模型具有年度随机财富乘法过程，然后根据线性财富相关税率缴纳税款。如果贫穷的代理人比富有的代理人支付更高的税率，最终所有的财富都集中在一个代理人手中。相比之下，如果贫困代理人的税率较低，那么经济集体进程将永远持续下去。
