Based on the current economic output and the potential output, the government should decrease spending by $12 billion.
First find the difference between the potential output and the current output:
= 2.42 - 2.40
= $0.02 trillion
= $20 billion
Then find the expenditure multiplier:
= 1 / ( 1 - Marginal propensity to consume)
= 1 / ( 1 - 0.4)
= 1.67
The government should reduce spending by:
= Difference between potential and current / Multiplier
= 20 / 1.67
= $12 billion
In conclusion, the government should reduce spending by $12 billion.
