Answer:
Differences in expected inflation, and on expected changes in the real exchange rate.
Step-by-step explanation:
Interest rate is the rate charged by a lender on monies borrowed
For example if 100 is borrowed, and the lender expects the borrower to pay 10 every month. The interest rate = (10/100) = 10%
According to the taylor equation
(1 + Nominal interest rate) = ( 1 + real interest rate) + (1 + inflation rate)
the higher the real interest rate and inflation rate, the higher the nominal interest rate
Real interest rate is interest rate less inflation rate
Nominal interest rate includes inflation rate
