Answer: Japan has the higher real interest rate.
Step-by-step explanation:
Japan:
Nominal interest rate = 5%
Inflation rate = 2%
Real interest rate = Nominal interest rate - Inflation rate
= 5 - 2
= 3%
United States:
Nominal interest rate = 7%
Inflation rate = 6%
Real interest rate = Nominal interest rate - Inflation rate
= 7 - 6
= 1%
∴ Japan has the higher real interest rate.
