Suppose that the current 1-year rate (1-year spot rate) and expected 1-year T-bill rates over the following three years (i.e., years 2, 3, and 4, respectively) are as follows: ₁R₁ = 6%, E(₂r₁) = 7%, E(₃r₁) = 7.60%, E(₄r₁) = 7.95% Using the unbiased expectations theory, calculate the current (long-term) rates for 1-, 2-, 3-, and 4-year-maturity Treasury securities. (Round your answers to 2 decimal places.)
