When the change in equilibrium level of real GDP equals 9 and change in autonomous aggregate expenditures equals 3, then, the multiplier will be 3.
Multiplier helps to measures how much a changes is in response to a change in other variable.
Given Information
Change in equilibrium level of GDP = 9
Change in autonomous expenditure = 3
Multiplier = (9 /3)
Multiplier = 3.
Therefore, when the change in equilibrium level of real GDP in the aggregate expenditures model is 9 and the change in autonomous aggregate expenditures is 3, then, the multiplier will be 3.
