Answer:
increase by 400 billion dollars
Explanation:
marginal propensity to consume = mpc
tax multiplier = -mpc/1-mpc
from our question we were given mpc to be 0.8
-0.8/1-0.8
= -0.8/0.2
= -4
change in output = -4(-100)
= 400 billion dollars
for a $100 tax decrease, output will increase by $100 billion x 4
= $400 billion
