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.
Marginal Cost and Average Cost curves. Average Total Cost is the sum of average variable cost and average fixed cost. or we can say, average cost is equal to the total cost divided by the number of units produced. Marginal Cost is the addition made to the total cost by producing 1 additional unit of output.
