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.

ELASTICITY The relative response of one variable to changes in another variable. Elasticity is commonly used in the study of market exchanges to identify the relative response of quantity (demanded and supplied) to changes in price. The phrase "relative response" is best interpreted as the percentage change, such as, the percentage change in quantity measured against the percentage change in price. The most common notions of elasticity are the price elasticity of demand and the price elasticity of supply. Other notable economic elasticities are the income elasticity of demand and the cross elasticity of demand.
