Question 2 (a) Consider a two-period consumption model consisting of now, t = 0, and next year, t = 1. There are two investors, Investor A who is patient and wants to wait and consume the maximum amount possible at t = 1, and Investor B who is impatient and wants to consume the maximum amount possible now. Both investors have an income of $200,000 today and no income at t = 1. Both investors have access to a real investment opportunity costing $200,000 now and returning a guaranteed $215,000 at t = 1. They also have access to risk-free borrowing and lending at an annual rate of 10%. Explain the investment decisions taken by each investor (both real and financial) and the resultant cash flows and consumption, including a brief discussion of the optimality of the net present value (NPV) rule.
