Assume that the real risk-free rate, r*, is 4 percent, and that inflation is expected to be 9% in Year 1, 6% in Year 2, and 4% thereafter. Assume also that all Treasury bonds are highly liquid and free of default risk. If 2-year and 5-year Treasury bonds both yield 12%, what is the difference in the maturity risk premiums (MRPs) on the two bonds, i.e., what is MRP₅ MRP₂?
