Average costs are U-shaped, and the marginal cost curve intersects the average cost curves at their respective minimum points. In the competitive model of the firm, the minimum average variable cost is termed the shutdown point because a firm will not produce in the short run if price is below average variable cost.
CHARACTERISTICS OF THE MARGINAL COST CURVE interval and from 76.7 percent to 85.5 percent for the 800-pound interval. As the interval is moved to the right, the marginal cost increases from $18.52 to $20.61 for the 1000-pound interval and from $15.38 to $17.12 for the 800-pound interval.
