1. The real risk-free rate is 4%. Inflation is expected to be 2% this year, 3% next year, and then 4% thereafter. The maturity risk premium is estimated to be 0.0003 x (t - 1), where t = number of years to maturity. What is the nominal interest rate on a 7-year Treasury security? Round your answer to two decimal places.

2. Assume that the real risk-free rate, r*, is 3% and that inflation is expected to be 7% in Year 1, 5% in Year 2, and 3% thereafter. Assume also that all Treasury securities are highly liquid and free of default risk. If 2-year and 5-year Treasury notes both yield 10%, what is the difference in the maturity risk premiums (MRPs) on the two notes; that is, what is MRP5 minus MRP2? Round your answer to two decimal places.
