摘要翻译：
研究了一个混合种群信任博弈的动力学问题，在这个博弈中，具有购买者角色的个体被迫与预定数量的销售者进行博弈，销售者是他们动态选择的。作为销售商的代理商也可以根据收益调整其产品的物有所值水平。在战略更新率的特定值下，动态经历了一个转变，超过这个值，就会观察到一个新兴的卡特尔组织，在那里卖方有类似的低于最优货币价值的价值。这种卡特尔组织不是由于代理人之间的明确勾结；相反，它是从个人收益最大化中自发产生的。这种动态的特点是大部分参数空间的波动很大，而且高度不可预测，这是对某些商品价格所观察到的高水平和波动的一种合理的定性解释。

英文摘要：
  We investigate the dynamics of a trust game on a mixed population where individuals with the role of buyers are forced to play against a predetermined number of sellers, whom they choose dynamically. Agents with the role of sellers are also allowed to adapt the level of value for money of their products, based on payoff. The dynamics undergoes a transition at a specific value of the strategy update rate, above which an emergent cartel organization is observed, where sellers have similar values of below optimal value for money. This cartel organization is not due to an explicit collusion among agents; instead it arises spontaneously from the maximization of the individual payoffs. This dynamics is marked by large fluctuations and a high degree of unpredictability for most of the parameter space, and serves as a plausible qualitative explanation for observed elevated levels and fluctuations of certain commodity prices.
