Answer:
increase by $800
Explanation:
if taxes decrease by 200 then
GPD x tax multipler = net impact on GDP
the tax multiplier is calculated as follows:
[tex]\frac{MPC}{1 - MPC}[/tex]
[tex]\frac{0.8}{1 - 0.8} = \frac{0.8}{0.2}[/tex]
multiplier = 4
tax variation x multiplier
200 x 4 = 800
As the taxes decreases the effect on the GDP is positive.
