By how much would government spending have to rise to shift the aggregate demand curve rightward by $30 billion?
Government spending multiplier:
To calculate government spending multiplier (Kg) using MPC:
(1-0.8)*30B
=$6B
The government should increase its spending by $6B in order to archives $30B increase in the level of output.
Tax Multiplier:
Calculate tax multiplier (Kt) by using MPC:
The government should decrease taxes by $7.5B to achieve $30B increase in the level of output.
