Suppose that the current one-year rate (one-year spot rate) and expected one-year T-bill rates over the following three years (ie, years 2.3, and 4, respectively) are as follows: 1R1 - 0.50, E12r 1) - 1.51, (371) - 7.71, (471) - 8.058 Using the unbiased expectations theory, calculate the current (long-term) rates for one, two, three-, and four-year-maturity Treasury securities.
