SIMPLE EXPENDITURE MULTIPLIER: The ratio of the change in aggregate output (or gross domestic product) to an autonomous change in an aggregate expenditure (consumption expenditures, investment expenditures, government purchases, or net exports) when consumption is the only induced expenditure. This is the least complicated expenditure multiplier possible, based exclusively on induced consumption, and is the inverse of the marginal propensity to save. This simple multiplier becomes more complicated by adding other induced expenditures.

PERFECTLY INELASTIC

An elasticity alternative in which changes in one variable (usually price) do NOT cause any changes in another variable (usually quantity). Quantity is totally, completely unresponsive to price. Quantity just does not change, regardless of changes in price. This characterization of elasticity is most important for the price elasticity of demand and the price elasticity of supply. Perfectly inelastic is one of five elasticity alternatives. The other four are perfectly elastic, relatively elastic, relatively inelastic, and unit elastic.
