答案和详解如下： Q1. Which one of the following statements best describes the components of the required interest rate on a security? A) The nominal risk-free rate, the expected inflation rate, the default risk premium, a liquidity premium and a premium to reflect the risk associated with the maturity of the security. B) The real risk-free rate, the default risk premium, a liquidity premium and a premium to reflect the risk associated with the maturity of the security. C) The real risk-free rate, the expected inflation rate, the default risk premium, a liquidity premium and a premium to reflect the risk associated with the maturity of the security. Correct answer is C) The required interest rate on a security is made up of the nominal rate which is in turn made up of the real risk-free rate plus the expected inflation rate. It should also contain a liquidity premium as well as a premium related to the maturity of the security. Q2. T-bill yields can be thought of as: A) nominal risk-free rates because they do not contain an inflation premium. B) real risk-free rates because they contain an inflation premium. C) nominal risk-free rates because they contain an inflation premium. Correct answer is C) T-bills are government issued securities and are therefore considered to be default risk free. More precisely, they are nominal risk-free rates rather than real risk-free rates since they contain a premium for expected inflation. Q3. The real risk-free rate can be thought of as: A) exactly the nominal risk-free rate reduced by the expected inflation rate. B) approximately the nominal risk-free rate reduced by the expected inflation rate. C) approximately the nominal risk-free rate plus the expected inflation rate. Correct answer is B) The approximate relationship between nominal rates, real rates and expected inflation rates can be written as: Nominal risk-free rate = real risk-free rate + expected inflation rate. Therefore we can rewrite this equation in terms of the real risk-free rate as: Real risk-free rate = Nominal risk-free rate – expected inflation rate The exact relation is: (1 + real)(1 + expected inflation) = (1 + nominal)
