Question 4 (14 marks) Lisbon is indifferent between investing all her wealth (which is $1 million) in the risky asset and the risk-free asset. The risky asset has an expected rate of return of 10% per year and a standard deviation of 20% per year. The risk-free lending rate is 4% per year. The risk-free borrowing rate is 6%. Answer the following questions. a) Compute Lisbon's risk aversion coefficient (A). [Hint: Note the meaning of lending rate and borrowing rate and recall the utility function that we covered in class. You may want to look at Bodie to get a better idea of the utility function to avoid calculation error.) (3 marks) b) Determine the optimal mix of the risky and the risk-free asset for Lisbon given your answer to (a). (3 marks) c) Mr. Jane (full name: Patrick Jane), a friend of Lisbon, is a hedge fund manager. He offers a truly risk-free investment opportunity of 7% per year to Lisbon, provided she can invest a minimum of $1 million. Lisbon realizes that in order to take advantage of this opportunity, she has to invest all her wealth with Patrick Should Lisbon invest all her wealth with Patrick earning a risk-free rate of 7% instead of holding the optimal mix computed in (b) above?
