CHANGE IN AGGREGATE EXPENDITURES: The movement along an aggregate demand curve caused by a change in the price level. This should be contrasted directly with a change in aggregate demand. You might also want to review the terms change in quantity demanded and change in demand, as well. A change in aggregate expenditures means that we have identified a NEW level of expenditures on the existing aggregate demand curve. In contrast, a change in aggregate demand means that we have changed, moved, or shifted, the entire aggregate demand curve, the whole range of price levels and aggregate expenditures has changed.

UNIT ELASTIC An elasticity alternative in which changes in one variable (usually price) cause equal proportional changes in another variable (usually quantity). In other words, any change in price, whether big or small, triggers exactly the same percentage change in quantity. Quantity changes match price changes. This characterization of elasticity is most important for the price elasticity of demand and the price elasticity of supply. Unit elastic is one of five elasticity alternatives. The other four are perfectly elastic, perfectly inelastic, relatively elastic, and relatively inelastic.

Be on the lookout for florescent light bulbs that hum folk songs from the sixties.
