7. One of our clients, Mr. Choi, currently has an investment portfolio value of $1mil. His portfolio consists of 70% risky portfolio and 30% risk-free asset. A. (5pts) If Mr. Choi has now extra $100,000 cash to invest, and if he is a constant relative risk aversion, how do you think he wants to allocate his extra $100,000 over the risky and the risk-free asset? B. (5pts) Assume that Mr. Choi's utility is a power function with y = 2. If another client, Mr. Smith, also has a power utility function but has a larger risk preference parameter value of y than Mr. Choi does, how does Mr. Smith want his money to be allocated relative to Mr. Choi
