摘要:

This paper investigates the implication of correlation ambiguity for investors' decision making and limited participation under market equilibrium. In our multi-asset model with inside, sophisticated, naive, and noise investors, individual decision making incorporates both risk and ambiguity. Sophisticated and naive investors trade in the same direction as inside investors, while naive investors trade in the same direction as sophisticated investors. Furthermore, noise investors trade in the same direction as sophisticated and naive investors. We demonstrate that limited participation arises from the rational decision by sophisticated and naive and noise investors to avoid correlation ambiguity. Comparative static analysis of the equilibrium result suggests that changes in the ambiguity level for sophisticated and naive investors and the fraction of four types of investors can alter equilibrium types and affect equilibrium prices. We also observe flight to quality phenomenon. Under equilibrium, the investors with less information could trade more intensively than the investors with more information in one of the risky assets.

本文研究了在市场均衡下投资者决策与有限参与间相关系数暧昧性的含义。在我们的多资产模型中,内幕、成熟、天真和噪音四种类型的投资者,其个人决策既有风险又具有暧昧性。成熟和天真的投资者与内幕投资者的交易方向保持一致,同时天真投资者与成熟投资者的交易方向相同。此外,噪音投资者也与成熟和天真的投资者的交易方向相同。我们证明,有限参与是由成熟、天真和噪音的投资者的理性决策所引起的,用以避免相关系数的暧昧性。均衡结果的静态比较分析表明,成熟和天真的投资者的暧昧性水平变化和四种类型投资者所占比例可以改变均衡类型并影响均衡价格。我们同时也观察到逃往质量现象的影响。在均衡状态下,获得信息较少的投资者比获得信息较多的投资者在风险资产中交易更为集中。
