Answer:
The answer is:
1. consumers' expenditure increases by $150 billion
2. output will decrease by $600 billion
Step-by-step explanation:
Tax impact:
$300 billion x 0.5
= $150 billion.
If taxes are lowered by $300 billion, consumers' expenditure increases by $150 billion because with lower tax, there is money money to be spent because their disposable income has increased.
Government spending impact:
$300/(1-0.5)
$300/0.5
=$600 billion.
Due to government spending that has increased by this amount, output will decrease by this amount too because government has directly competed with firms that should have used this money to increase the total output.
Therefore, net effect on total output is $300billion($600 - $300)
