Answer:
1) 6% , 2) 5% , 3) As inflation rate ise higher than expected inflation rate, real interest rate would be lower than expected real interest rate
Explanation:
Real Interest Rate is the interest rate, which accounts for the impact of inflation.
Real Interest Rate = Nominal Interest Rate - Inflation
1) 14% - 8% = 6%
2) 14% - 9% = 5%
3) In case of variation in expected & actual inflation rate
1 + nominal interest rate = (1 + real interest rate) (1 + expected inflation rate)
1 + 14% = (1 + r) (1 + 3%)
1.14 = (1 + r) (1.03)
1.14 = 1.03 + 1.03r
0.11 = 1.03r
r = 8.82 {If inflation is higher at 9%}
If inflation could have been at expected 3%, real interest rate could have been 14% - 3% = 11%.
So : As inflation rate turned out to be higher than expected inflation rate, real interest rate turned out to be lower than expected real interest rate
