ADJUSTMENT, LONG-RUN AGGREGATE MARKET: Disequilibrium in the long-run aggregate market induces changes in the price level that restore equilibrium. If the price level is above the long-run equilibrium price level, economy-wide product market surpluses cause the price level to fall. If the price level is below the long-run equilibrium price level, economy-wide product market shortages cause the price level to rise. In both cases long-run equilibrium is restored. Price level changes induce changes in aggregate expenditures but NOT changes in real production. The reason is that long-run aggregate supply is full-employment real production, which is unaffected by the price level.

PERFECT COMPETITION, LONG-RUN ADJUSTMENT: A perfectly competitive industry undertakes a two-part adjustment to equilibrium in the long run. One is the adjustment of each perfectly competitive 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 eliminate economic profit or economic loss. The end result of this long-run adjustment is a multi-faceted equilibrium condition that price is equal to marginal cost and average cost (both short run and long run).

MARGINAL REVENUE PRODUCT AND FACTOR DEMAND A perfectly competitive firm's factor demand curve is that negatively-sloped portion of its marginal revenue product curve. A perfectly competitive firm maximizes profit by hiring the quantity of input that equates factor price and marginal revenue product. As such, the firm moves along its negatively-sloped marginal revenue product curve in response to changing factor prices.
