Suppose that the current 1-year rate (1-year spot rate) and expected 1-year T-bill rates over the following three years (l.e. years 2.3, and 4 , respectively) are as follows: 1R1=6%,E(2r1)=7%,E3)=7.70%,E(ar1)=8.05% Using the unbiased expectations theory, calculate the current (long-term) rates for one-, two-, three-, and four-year-maturity Treasury securities. (Round your answers to 2 decimal places.)
