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.
