An investor in Treasury securities expects inflation to be 2.5% in Year 1, 3.35% in Year 2, and 4.25% each year thereafter. Assume that the real risk-free rate is 2.3% and that this rate will remain constant. Three-year Treasury securities yield 6.60%, while 5-year Treasury securities yield 8.15%. What is the difference in the maturity risk premiums (MRPs) on the two securities; that is, what is MRP5 - MRP3? Do not round intermediate calculations. Round your answer to two decimal places.
