CHANGE IN AGGREGATE DEMAND: A shift of the aggregate demand curve caused by a change in one of the aggregate demand determinants. In essence, a change in aggregate demand is caused by any factor affecting aggregate demand EXCEPT the price level. This concept should be contrasted directly with a change in aggregate expenditures. You might also want to review the terms change in quantity demanded and change in demand, as well. The change in aggregate demand is comparable to the change in market demand. A change in aggregate demand is a change in ALL price level-aggregate expenditure combinations, meaning that each price level is matched up with a different aggregate expenditure (which is illustrated as a shift of the aggregate demand curve). This change in aggregate demand is caused by a change in any of the aggregate demand determinants. In contrast, a change in aggregate expenditures is a change from one price level-aggregate expenditure combination to the another (which is illustrated as a movement along a given aggregate demand curve).

CONCENTRATION RATIOS

A family of measures of the proportion of total output in an industry that is produced by a given number of the largest firms in the industry. The two most common concentration ratios are for the four largest firms and the eight largest firms. The four-firm concentration ratio is the proportion of total output produced by the four largest firms in the industry and the eight-firm concentration ratio is proportion of total output produced by the eight largest firms in the industry. Concentration ratios are commonly used to indicate the degree to which an industry is oligopolistic and the extent of market control of the largest firms in the industry. A related measure is the Herfindahl index.
