问题如下:
Belen Zapata is a risk-seeking investor. He will apply utility theory to choose the investment portfolio. The table shows the expected return and expected standard deviation of several investments, assuming the measure of risk aversion is -3, he is most likely to invest:
选项:
A.2
B.3
C.4
解释:
C is correct
Investment 4 has the highest Utility Value(0.3738).
U=E(R)-0.5*A*(standard deviation)^2
0.19-0.5*3*(0.03)^2=0.18865
0.21-0.5*3*(0.09)^2=0.19785
是我算错了吗?所有的U的结果都不对
