An investor in Treasury securities expects inflation to be 3 percent in Year 1, 4 percent in Year 2, and 5 percent each year thereafter. Assume that the real risk-free rate is 3 percent, and that this rate will remain constant over time. Two-year Treasury securities yield 6.8 percent, while 4-year Treasury securities yield 7.6 percent. What is the difference in the maturity risk premiums (MRPs) on the two securities, that is, what is MRP₄ - MRP₂?
