Unbiased Expectations Theory Suppose that the current one-year rate (oneyear 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=7%, E(2r1) =9%, E(3r1) =6.0% E(4r1)=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 + 1R1)(1 + E(2r1))] 1/2 - 1

Rate for a three year security = [(1 + 1R1)(1 + E(2r1))(1 + E(3r1))] 1/3 - 1

Rate for a four year security = [(1 + 1R1)(1 + E(2r1))(1 + E(3r1))(1 + E(4r1))] 1/4 - 1
