Answer:
The appropriate solution is "100 billion".
Explanation:
The given values are:
Recessionary gap (Total change),
= $500
Marginal propensity consume (MPC),
= 0.8
Now,
Multiplier will be:
= [tex]\frac{1}{1-MPC}[/tex]
On putting the value of MPC, we get
= [tex]\frac{1}{1-0.8}[/tex]
= [tex]5[/tex]
As we know,
⇒ [tex]Total \ change=Government \ spending's \ increase\times Multiplier[/tex]
⇒ [tex]Government \ spending's \ increase=\frac{Total \ change}{Multiplier}[/tex]
On substituting the values, we get
⇒ [tex]=\frac{500}{5}[/tex]
⇒ [tex]=100 \ billion[/tex]
