SanBlas Jewels has requested is that of equation (21) in the text: Nominal interest rate = real risk-free interest rate + inflation premium + default-risk premium + maturity-risk premium + liquidity-risk premium Some agreed-upon procedures related to generating estimates for key variables in equation (2-1) follow. b. The real risk-free rate of interest is the difference between the calculated average yield on 3-month Treasury bills and the inflation rate. c. The default-risk premium is estimated by the difference between the average yields on AAA-rated bonds and 30 -year Treasury bonds. d. The maturity-risk premium is estimated by the difference between the average yields on 30-year Treasury bonds and 3-month Treasury bills. What is the real risk-free interest rate? % (Round to two decimal places.) What is the inflation premium? \% (Round to two decimal places.) What is the default-risk premium? \%( (Round to two decimal places.) What is the maturity-risk premium? \% (Round to two decimal places.)
