MARGINAL PROPENSITY TO SAVE: The proportion of each additional dollar of household income that is used for saving. Or alternatively, this is the change in saving due to a change in disposable income. Abbreviated MPS, the marginal propensity to save is the slope of the saving or propensity-to-save line. It also takes center stage for the multiplier effect. In particular, the inverse of the MPS is the simple expenditure multiplier. The sum of the marginal propensity to save and the related concept, the marginal propensity to consume, is equal to one.

LONG-RUN AVERAGE COST CURVE, DERIVATION The long-run average cost curve is the envelope of an infinite number of short-run average total cost curves, with each short-run average total cost curve tangent to, or just touching, the long-run average cost curve at a single point corresponding to a single output quantity. The key to the derivation of the long-run average cost curve is that each short-run average total cost curve is constructed based on a given amount of the fixed input, usually capital. As such, when the quantity of the fixed input changes, the short-run average total cost curve shifts to a new location.
