LONG-RUN ADJUSTMENT: The combined adjustment of an industry and of each firm in the industry to an equilibrium condition that based on (1) profit maximization when all inputs are variable and (2) the entry and exit of firms. The complete adjustment is undertaken by both perfect competition and monopolistic competition. There are two parts of this adjustment process. One is the adjustment of each firm to the appropriate factory size that maximizes long-run profit. The other is the entry of firms into the industry or exit of firms out of the industry, to eliminated economic profits or economic losses. The end result of this long-run adjustment is different for the two market structures based on the fact that perfect competition has equality between price and marginal revenue, while monopolistic competition does not.

CONSUMER CONFIDENCE, AGGREGATE DEMAND DETERMINANT One of several specific aggregate demand determinants assumed constant when the aggregate demand curve is constructed, and which shifts the aggregate demand curve when it changes. An increase in consumer confidence causes an increase (rightward shift) of the aggregate demand curve. A decrease in consumer confidence causes a decrease (leftward shift) of the aggregate demand curve. Other notable aggregate demand determinants include interest rates, federal deficit, inflationary expectations, and the money supply.
