What is the Maturity risk premium( MRP) on all 5 yr bonds?

To calculate the Maturity Risk Premium (MRP) on all 5-year bonds, we need to subtract the risk-free rate from the yield of the Kelly Inc bond. The formula to calculate the MRP is as follows:

MRP = Yield on Kelly Inc Bond - Risk-Free Rate

Given the following information:
- Yield on Kelly Inc's 5-year bond = 7.50%
- Risk-Free Rate (r*) = 2.5%

Using the formula, we can calculate the MRP:

MRP = 7.50% - 2.5% = 5.00%

Therefore, the Maturity Risk Premium on all 5-year bonds is 5.00%.
