问题如下:
With respect to an investor’s utility function expressed as:U=E(r)-1/2Aσ2 , which of the following values for the measure for risk aversion has the least amount of risk aversion?
选项:
A.-4.
B.0.
C.4.
解释:
A is correct.
A negative value in the given utility function indicates that the investor is a risk seeker.
Risk averse 的A不应该是正数吗?Risk seeking才是负数。那对于risk averse的人来说不是在大于0的情况下最小的那个数吗?
