Answer:
equilibrium GDP increase by 1 as well.
Step-by-step explanation:
As government spending multiplier is:
1/(1 - marginal propensity to consume)
while taxes is:
marginal propensity to consume / ( 1 - marginal propensity to consume)
the multiplier when considering an increase in government spending financed with taxes will be:
government multiplier - tax multiplier
( 1 - marginal propensity to consume)/ ( 1 - marginal propensity to consume) = 1
as the multiplier is 1 and increase of 1 will mean an increase of 1 unit in the equilibrium GDP as weill
