Answer #1

A.

Given,

risk aversion of the investor (A) = 4

standard deviation of portfolio (Sd) = 16%

Weight in the stock (W) = 1

weight of the risky portfolio formula:

W = (Rm - Rf)/A*Sd2

Rm - Rf = 1*0.04*16*16 = 10.24%

So, implied risk premium(Rm - Rf) = 10.24% (Answer)

B.

When A = 2

Implied risk premium (Rm - Rf) = 1*0.02*16*16 = 5.12% (Answer)
