Marginal propensity to consume (mpc = c = AC/AY): the change in consumption expendi-
ture caused by a change in income.
Marginal propensity to import (mpm = m = AIM/AY): the change in imports caused by a
change in income.
Induced expenditure (c-m)Y: planned consumption and imports expenditures that change
when income changes.
Autonomous expenditure (A): planned expenditure that is not determined by current income.
Aggregate expenditure (AE): the sum of planned induced and autonomous expenditure in
the economy.
Short-run equilibrium output: Aggregate expenditure current output are equal (Y = AE).
Unplanned changes in business inventories: indicators of disequilibrium between planned
and actual expenditures incentives for businesses to adjust levels of employment and output
(Y).
Multiplier (AY/AA): the ratio of the change in equilibrium income Y to the change in au-
tonomous expenditure A that caused it.
