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: 1A1 = 0.5%. Er 1) = 1.5%. Ein) = 7.2% E4n) - 7.556 Using the unbiased expectations theory, calculate the current (long-term) rates for one, two, three-, and four-year-maturity Treasury securities.
