金融经济学中的层次因果关系

Hierarchical causality in financial economics

Diane Wilcox, Tim Gebbie

摘要:

为了探讨金融经济学中的因果性、机会性和复杂性,考虑了层次分析,提出了一个多层次模型。一个耦合的模型系统被用来描述多层次的相互作用,与市场数据相一致:最低层是由代理人占据的,产生单个交易资产的价格;下一层需要将股票聚集到市场中;第三层将共同的风险因素与信息变量和自下而上的代理人产生的结构相结合,与无套利定价理论的条件相一致;第四个层次描述的是源于更大经济的市场因素,最高层次则是受管制的市场结构以及界定可接受交易性质的习俗和道德。出现或创新的机制被认为是和因果关系的来源进行了讨论的五个因果关系类。

英文摘要:

Hierarchical analysis is considered and a multilevel model is presented in order to explore causality, chance and complexity in financial economics. A coupled system of models is used to describe multilevel interactions, consistent with market data: the lowest level is occupied by agents generating the prices of individual traded assets; the next level entails aggregation of stocks into markets; the third level combines shared risk factors with information variables and bottom-up, agent-generated structure, consistent with conditions for no-arbitrage pricing theory; the fourth level describes market factors which originate in the greater economy and the highest levels are described by regulated market structure and the customs and ethics which define the nature of acceptable transactions. A mechanism for emergence or innovation is considered and causal sources are discussed in terms of five causation classes.
