论文摘要
为了描述财富分配的演变，几种模型考虑了以二元方式交流财富的相互作用的经济代理人的合奏。有趣的是，考虑到一个公正的市场的模型，这给每个代理商带来了同样的机会在游戏中获胜的机会，始终是均衡的，直到达到最终状态的完美不平等为止。在这里，我们提出了一个严格的分析证明，即任何由公正的二进制交换驱动的系统都注定要驱动系统以完善不平等和零迁移率。
Aiming to describe the wealth distribution evolution, several models consider an ensemble of interacting economic agents that exchange wealth in binary fashion. Intriguingly, models that consider an unbiased market, that gives to each agent the same chances to win in the game, are always out of equilibrium until the perfect inequality of the final state is attained. Here we present a rigorous analytical demonstration that any system driven by unbiased binary exchanges are doomed to drive the system to perfect inequality and zero mobility.
