e Cridpter. 32. Suppose that the current one year rate (one-year spot rate) and expected one ear T-bill rates over the following three years (i.e, years 2, 3, and 4, respec tively) are as follows: IR,26% E(2A) 7% E(3r.) 7.5% E(4r1) 7.85% Using the unbiased expectations theory, calculate the current (long-term) rates for one, two, three, and four-year-maturity Treasury securities. Plot the resulting yield curve
