The aggregate demand curve is
Similar to the normal demand curve
The AD curve can
Shift
It might shift to the right
It might shift to the left
The multiplier effect leads to
A larger increase in aggregate demand
Average propensity to consume or save
Shows what happens to incomes
The marginal propensity to consume or save
Affects the size of the multiplier
Learn the formula for
Calculating the multiplier from the MPC
Multiplier =
1 / 1 - MPC
The marginal propensity to withdraw can also
Be used to find the multiplier
MPW =
withdraw
MPS + MPT + MPM
Save
Tax
Import
Learn formula for calculating multiplier from the MPW
MPC + MPW = 1
Multiplier = 1/MPW
