基于前景理论的交易行为如何影响价格波动
文章 arXiv papers · 作者: Yipeng Yang et al.
总结
本文提出一种微观经济模型,其中市场参与者作为前景理论主体,对收益和损失作出反应。价格由供需之间的暂时均衡形成,因此参与者的决策会反馈到价格过程中。该模型将交易行为的这种反馈与价格波动联系起来。
作者认为,这种机制可以解释实际市场中观察到的隐含波动率偏斜和微笑形态。本文提供的是概念性解释,没有涉及校准或实证检验的细节。文中没有说明资产、数据,也没有说明模型的推论能否转化为交易策略。
核心观点
- 模型将市场价格视为供需暂时均衡的结果。
- 前景理论主体会根据收益和损失调整自身行为。
- 参与者的交易行为会反馈到价格过程及其波动中。
- 研究用所提出的反馈机制解释隐含波动率偏斜和微笑形态。

# Prospect Agents and the Feedback Effect on Price Fluctuations # Prospect Agents and the Feedback Effect on Price Fluctuations A microeconomic approach is proposed to derive the fluctuations of risky asset price, where the market participants are modeled as prospect trading agents. As asset price is generated by the temporary equilibrium between demand and supply, the agents' trading behaviors can affect the price process in turn, which is called the feedback effect. The prospect agents make actions based on their reactions to gains and losses, and as a consequence of the feedback effect, a relationship between the agents' trading behavior and the price fluctuations is constructed, which explains the implied volatility skew and smile observed in actual market.
