Suppose that the current one-year rate (one-year spot rate) and expected one-year T-bill rates over the following three years (i.e., years 2, 3, and 4, respectively) are as follows: 1R1 - 0.5*, B(271) - 1.54, (3-1) = 8.71, 8(451) - 9.054 Using the unbiased expectations theory, calculate the current (long-term) rates for one, two, three-, and four-year-maturity Treasury securities.
