Suppose that the current 1-year rate (1-year spot rate) and expected 1-year T-bill rates over the following three years (i.e., years 2 , 3, and 4 , respectively) are as follows: 1R1=2.50%,E(2r1)=3.75%,E(3r1)=4.25%,E(4r1)=5.75% Using the unbiased expectations theory, calculate the current (long-term) rates for one-, two-, three-, and four-year-maturity Treasury securities. (Do not round intermediate calculations. Round your answers to 2 decimal places.)
