英文摘要：
We study the collective behavior of interacting agents in a simple model of market economics originally introduced by N{\\o}rrelykke and Bak. A general theoretical framework for interacting traders on an arbitrary network is presented, with the interaction consisting of buying (namely, consumption) and selling (namely, production) of commodities. Extremal dynamics is introduced by having the agent with least profit in the market readjust prices, causing the market to self--organize. We study this model market on regular lattices in two--dimension as well as on random complex networks; in the critical state fluctuations in an activity signal exhibit properties that are characteristic of avalanches observed in models of self-organized criticality, and these can be described by power--law distributions.

中文摘要：
我们在一个简单的市场经济模型中研究相互作用主体的集体行为，该模型最初由N{\\o}rrelykke和Bak提出。提出了一个任意网络上交易者交互的一般理论框架，交易者的交互包括商品的购买（即消费）和销售（即生产）。极值动态是通过让市场中利润最少的代理调整价格，使市场自我组织而引入的。我们研究了二维正则格和随机复杂网络上的市场模型；在临界状态下，活动信号的波动表现出自组织临界模型中观察到的雪崩特性，这些特性可以用幂律分布来描述。
