U=E(r)-1/2Aσ^2, 已知measure for risk avesion is 2,也就是A=2,

以investment 1为例,U=0.18-1/2*2*(0.02)^2=0.1796

If investor’s utility function is expresseanthe measure for risk aversion ha value of 2。这句话的意思不是utility function=2?‘utility function的公式,A表示utility function还是U表示utility function?

老师好,想问下这种题为什么都要代入公式呢如果厌恶风险为什么不选择sigma最小的就好了呢,还是因为风险厌恶的人可以承担风险只不过相应的要得到更多的收益所以进行utility的比较吗,谢谢
