Answer:
$5,000 billion
Explanation:
We know that
Government spending multiplier = 1 ÷ (1 - marginal propensity to consume)
Government spending multiplier = 1 ÷ (1 - 0.50)
Government spending multiplier = 1 ÷ 0.50
So, Government spending multiplier = 2
If the output is increased by $10,000 billion then, the government spending would rise by
= Output ÷ Government spending multiplier
= $10,000 ÷ 2
= $5,000 billion
