摘要翻译：
本文研究了N个主体系统中的两种经济交换：加法交换和乘法交换。该工作分为两个部分，在第一部分中，代理之间可以自由地进行交互。系统演化为具有加性交换的Boltzmann-Gibbs分布，并与乘法交换的Boltzmann-Gibbs分布凝聚。如果引入破产，两种类型的交换都会导致凝结。对凝结时间进行了研究。在第二部分中，代理被放置在一个社会网络中。我们分析了财富在时间上的分配行为，并在一定的网络连通性值下观察到经济阶级的形成。

英文摘要：
We study two kinds of economic exchange, additive and multiplicative, in a system of N agents. The work is divided in two parts, in the first one, the agents are free to interact with each other. The system evolves to a Boltzmann-Gibbs distribution with additive exchange and condenses with a multiplicative one. If bankruptcy is introduced, both types of exchange lead to condensation. Condensation times have been studied. In the second part, the agents are placed in a social network. We analyze the behavior of wealth distributions in time, and the formation of economic classes was observed for certain values of network connectivity.
