Suppose that the yield to maturity for all of these bonds changed instantaneously to 7%.What is the fair price of each bond now?c. Suppose that the yield to maturity for all of these bonds changed instantaneously again,this time to 9%. Now what is the fair price of each bond?d. Based on the fair prices at the various yields to maturity, is interest-rate risk the same,higher, or lower for longer- versus shorter-maturity bonds?
