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).
