Abstract

Information is an important issue in financial markets since information advantage leads to increased profits. This paper investigates whether those with less risk aversion or more risk aversion would like to be informed when there is private information which can be acquired for a certain cost. The CARA utility function and normal return assumptions were used to get the closed form solution of the absolute risk aversion coefficient which is indifferent to whether a person wants to be informed, which shows that the less risk aversion investor would like to be informed. The results further show that in financial markets, those people with lower risk aversion (for instance, institutional investors) are more favorable to information and price discovery of risky assets, which is consistent with intuition as well as empirical studies.

谁想要获得信息——更少的风险厌恶还是更多的风险厌恶?*
信息是金融市场中的一个重要问题,因为信息优势会导致利润的增加。本文考察了风险厌恶程度较低或风险厌恶程度较高的个体,在存在可以以一定成本获得的私人信息时,是否愿意被告知。利用CARA效用函数和正态收益假设,得到与是否愿意被告知无关的绝对风险厌恶系数的闭形式解,表明风险厌恶程度较低的投资者愿意被告知。结果进一步表明,在金融市场中,风险厌恶程度较低的人群(如机构投资者)更倾向于风险资产的信息和价格发现,这与直觉和实证研究一致。
