| Abstract: | This paper tests a theorem to the effect that the difference in nominal interest rates between two securities of the same maturity but different risk is an increasing linear function of the expected rate of inflation. When inflation is modelled in a way which is rational in the sense of Muth, the evidence is highly consistent with the theorem's inferences. Estimates are also obtained of the real risk premiums that certain types of securities generate over the three-month treasury bill rate (which is assumed to be risk-free). These range from three basis points for three-month finance paper to 16 basis points for three-month Eurodollar deposits. |
