英文摘要：
We present a model in which we investigate the structure and evolution of a random network that connects agents capable of exchanging wealth. Economic interactions between neighbors can occur only if the difference between their wealth is less than a threshold value that defines the width of the economic classes. If the interchange of wealth cannot be done, agents are reconnected with another randomly selected agent, allowing the network to evolve in time. On each interaction there is a probability of favoring the poorer agent, simulating the action of the government. We measure the Gini index, having real world values attached to reality. Besides the network structure showed a very close connection with the economic dynamic of the system.

中文摘要：
我们提出了一个模型，在该模型中，我们研究了连接能够交换财富的代理的随机网络的结构和演化。只有当邻居之间的财富差异小于定义经济阶层宽度的阈值时，才能发生经济互动。如果无法进行财富交换，代理将与另一个随机选择的代理重新连接，从而允许网络及时演化。在每一次互动中，都有可能偏向较穷的代理，模拟政府的行为。我们测量基尼指数，将现实世界的价值与现实联系起来。此外，网络结构与系统的经济动态有着非常密切的联系。
