Answer: The ex post real interest rate on this bond is 4%.
Ex post real interest rate refers to the real interest rate that accrues over a specific time period.
We can find the ex-post real interest rate on a bond by deducting the inflation rate from the nominal interest rate.
This is expressed as:
[tex]\mathbf{Ex post real interest rate = Nominal interest rate - inflation rate}[/tex]
[tex]\mathbf{Ex post real interest rate = 0.06 - 0.02}[/tex]
mathbf{Ex post real interest rate = 0.04}
