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 - 0.58, E12r 1) - 1.58, (371) - 7.78, (471) - 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 3 decimal places. (e.g., 32.161)) Current (Long-Term) Rates 0.500 One-year Two-year 1.000 3.1801 Three-year Four-year 4.3801
