P6-2 Unbiased Expectations Theory Suppose that the current one-year rate (one- year spot rate) and expected one-year T-bill rates over the following three years (.e., years 2, 3, and 4, respectively) are as follows: Ri=7%, E2n) =9%, (3n) -6.0% (17)=4% Using the unbiased expectations theory, calculate the current (long-term) rates for one-, two-, three-, and four-year-maturity Treasury securities. Show your answers in percentage form to 3 decimal places. Note that: Rate for a two year security [(1 + R) (1 + E(21)/2 - 1 Rate for a three year security [(1 + R) (1 + E(212) (1 + E(sn))/3 - 1 Rate for a four year security = [(1 + R.) (1 + E(2n) (1 +E(31) (1 + E())}/4 - 1
