Assume the following: The real risk-free rate, r* is expected to remain constant at 3%. Inflation is expected to be 3% next year and then tobe constant at 2% a year thereafter. The maturity risk premium is zero. Given this information, which of the following statements is CORRECT? The yield curve for U.S. Treasury securities will be upward sloping. O A 5-year corporate bond must have a lower yield than a 5-year Treasury security. O A 5-year corporate bond must have a lower yield than a 7-year Treasury security. The real risk-free rate cannot be constant if inflation is not expected to remain constant. O This problem assumed a zero maturity risk premium, but that is probably not valid in the real world
