Answer:
The correct answer is option A.
Explanation:
An economy is operating below its potential level.
The marginal propensity to consume is 0.8.
The amount of new government spending is $600 billion.
The change in the GDP will depend on the size of the spending multiplier.
ΔGDP
= [tex]\frac{1}{1-MPC}\ \times\ \Delta G[/tex]
= [tex]\frac{1}{1-0.8}\ \times\ 600[/tex]
= [tex]\frac{1}{0.2}\times\ 600\[/tex]
= $3,000 billion
