Answer: The answer is as follows:
Explanation:
Potential GDP = consumption + investment + government purchases + net export
= 300 + 50 + 100 + 20
= $470
If the full-employment level of GDP for this economy is $620 billion.
In this situation, potential GDP is less than the real output or GDP at full employment level. From the above calculation, the potential GDP is $470 and GDP at full employment is $620. So, there is a gap of $150 between Potential GDP and real output.
Therefore, government should increase the spending and cut down taxes to reduce the GDP-gap.
