【摘要】:社会网络从微观层面刻画了交易者的信息交流,对资产价格的研究具有重要意义。考虑到交易者交流的不确定性,本文基于金融市场中交易者的社会网络构建随机信息交流网络,并探究随机信息交流对资产价格及波动的影响。应用带噪音的理性预期均衡模型,本文推导出资产价格是信息共享度的函数。理论分析发现随机信息交流是影响资产价格波动的重要因素,数值模拟结果进一步验证了这一结论。
[Abstract]:Social network depicts the information exchange of traders from the micro level, which is of great significance to the study of asset prices. Based on the social network of traders in financial markets, this paper constructs a stochastic information exchange network, and explores the impact of random information exchange on asset prices and volatility. This paper deduces that asset price is a function of the degree of information sharing, and finds that random information exchange is an important factor affecting the fluctuation of asset price. The numerical simulation results further verify this conclusion.
