Explain why the industry supply curve is not the long-run industry marginal cost curve. The industry supply curve is not the long-run industry marginal cost curve because OA. production will only occur along the long-run marginal cost curve for prices above average variable cost. ● B. at prices above the minimum long-run average cost of production, firms will exit the industry. OC. production will only occur along the long-run marginal cost curve when profits are earned. OD. firms cannot change fixed inputs in the long run, resulting in an industry supply curve that equals a short-run marginal cost curve. OE. at prices above the minimum long-run average cost of production, firms will enter the industry.
