摘要翻译：
宏观价格演化模型是投资策略常用的模型。首先，在定义基于微观agent的模型以达到相同的目的方面取得了一些有希望的成就。微观模型比纯粹现象学的宏观模型能够更深刻地理解市场机制，从而为市场监管提供了更好的模型。我们在一个案例研究中举例说明了这一策略，从一个与伊辛模型密切相关的微观纺纱市场模型推导出一个宏观的朗之万方程。微观和宏观观点的相互作用使得我们能够更好地理解微观模型，并可以指导作为宏观价格模型基础的基于代理的市场模型的构建。

英文摘要：
  Macroscopic price evolution models are commonly used for investment strategies. There are first promising achievements in defining microscopic agent based models for the same purpose. Microscopic models allow a deeper understanding of mechanisms in the market than the purely phenomenological macroscopic models, and thus bear the chance for better models for market regulation. We exemplify this strategy in a case study, deducing a macroscopic Langevin equation from a microscopic spin market model closely related to the Ising model. The interplay of the microscopic and the macroscopic view allows for a better understanding of the microscopic model, as well, and may guide the construction of agent based market models as basis of macroscopic price models.
