Suppose that, holding yield constant, investors are inditferent as to whether thoy hold bonds issued by the lederal govemment or bonds issued by state and local governments (that ib, they consider the bonds the same with respect to defauit risk. information costs, and liquidity).

(Assume that the relovant federal income tax rate is 34.71%.) The pre-tax yleld on the state perpetuity will be 9 \%. (Round your response fo hwo decimai piaces.) The pre-tax yield on the federal perpetuity wis be *. (Round your response to two decimal places) Assuming that the liquidity premium theory is correct, on March 5,2010 , what did investors expect the interest rate to be on the one-year Treasury bill two years from that date if the term premium on a two-year Treasury note was 0.02% and the term premium on a three-year Treasury note was 0.07% ?
