Suppose that the current 1-year rate (1-year spot rate) and expected 1-year T-bill rates over the following three years (le, years 2,3. and 4, respectively) are as follows 1H1=318%,(2r1)=4.60%,E(3r1)=5.10%,E(4r1)=6.60% 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 onswers to 2 decimal places.)
