Solution :
Given :
The bonds offer a 
of 4.5% per year
Tax rate = 10% = 0.10
Inflation rate = 2
= + 
= 2 + 4.5
= 6.5
= 
= 
= 5.85
After tax real interest rate = 
-
= 5.85 - 2.0
= 3.85
= 7.0
= +
= 7 + 4.5
= 11.5
= 
= 10.35
= 11.5 x (1 - 0.10)
= 11.5 x 0.90
= 10.35
= -
= 10.35 - 7.0
= 3.35
Putting all the value in table :
Real interest Nominal interest After tax nominal After tax
rate rate interest rate interest rate
2.0 4.5 6.5 5.85 3.85
7.0 4.5 11.5 10.35 3.35
Comparing with the 
, a 
will increase the after after tax real interest rate when the government taxes nominal interest income. This tends to encourage saving, thereby increase the quantity of investment in the economy and the increase the economy's long-run growth rate.
Macroeconomics is important because it allows the public to understand the economy as a whole, fiscal policy and global economic policy.
Answer:
the real GDP in 2019 is $200
Explanation:
The computation of the real GDP is shown below;
= Base year price × quantity produced in 2019
= $1 × 200
= $200
Hence, the real GDP in 2019 is $200
The above should be used to determine the real GDP in 2019 and the same should be relevant
