人类集体行为的计算建模:以金融市场为例

Computational modeling of collective human behavior: Example of financial markets

Andy Kirou, Blazej Ruszczycki, Markus Walser, Neil F. Johnson

摘要:

我们讨论了如何最小的金融市场模型可以通过弥合两个现有的,但不完整的市场模型之间的差距:一个模型中,人口的虚拟交易者作出决定的基础上共同的全球信息,但缺乏当地的信息,从他们的社会网络,和一个模型中,交易者形成一个动态发展的社会网络,但缺乏任何决策的基础上,全球信息。我们表明,这两种模型的适当组合-特别是,人口的虚拟交易者访问全球和本地信息-产生的价格回报分布的结果更接近报告的程式化的事实。我们认为,这种类型的模型可以应用于广泛的系统中,其中集体人类活动被观察到。

英文摘要:

We discuss how minimal financial market models can be constructed by bridging the gap between two existing, but incomplete, market models: a model in which a population of virtual traders make decisions based on common global information but lack local information from their social network, and a model in which the traders form a dynamically evolving social network but lack any decision-making based on global information. We show that a suitable combination of these two models -- in particular, a population of virtual traders with access to both global and local information -- produces results for the price return distribution which are closer to the reported stylized facts. We believe that this type of model can be applied across a wide range of systems in which collective human activity is observed.
