Suppose there is some hypothetical closed economy in which households spend $0.80 of each additional dollar they earn and save the remaining
$0.20.
The marginal propensity to consume (MPC) for this economy is
and the spending multiplier for this economy is
Suppose the government in this economy decides to increase government purchases by $400 billion. The increase in government spending will lead
to an increase in income, creating an initial change in consumption equal to
. This increases income yet again, leading to a second
change in consumption equal to
The total change in demand resulting from the initial change in government spending is
The following graph shows the aggregate demand curve (ADI) for this economy before the change in government spending.
Use the green line (triangle symbol) to plot the new aggregate demand curve (AD₂) after the multiplier effect takes place. For simplicity, assume that
there is no "crowding out."
Hint: Be sure that the new aggregate demand curve (AD₂) is parallel to the initial aggregate demand curve (AD₁). You can see the slope of AD₁ by
