Suppose the real risk-free rate is 4.20%, the average expected future inflation rate is 4.20%, and a maturity risk premium of 0.10% per year to maturity applies, i.e., MRP = 0.10%(t), where t is the number of years to maturity. What rate of return would you expect on a 4-year Treasury security? Disregard cross-product terms.
