Why does marginal cost always cross the ATC curve at its lowest point?

Why does marginal cost always cross the ATC curve at its lowest point?

The marginal cost curve always intersects the average total cost curve at its lowest point because the marginal cost of making the next unit of output will always affect the average total cost. As a result, so long as marginal cost is less than average total cost, average total cost will fall.

Why does the MC curve cut the AVC curve at the minimum point of the AVC curve?

It happens because when Average Variable Cost (AVC) falls, Marginal Cost (MC) is less than AVC. When AVC starts rising, MC is more than AVC. So, it is only curve cuts AVC is constant and at its minimum point, that MC is equal to AVC. Therefore, MC curve cuts AVC curve at is minimum point.

Where does the marginal cost curve intersect the average total cost curve?

The marginal cost curve intersects the average total cost curve exactly at the bottom of the average cost curve—which occurs at a quantity of 72 and cost of $6.60 in Figure 1. The reason why the intersection occurs at this point is built into the economic meaning of marginal and average costs.

What is the lowest point on the average total cost curve?

The lowest point on the average total cost curve is at a point where marginal cost is equal to average total cost that is, at point E in the diagram. The marginal cost curve cuts the average total cost curve at its lowest point.

When marginal cost is less than average total cost?

Whenever marginal cost is less than average total cost, average total cost is falling. Whenever marginal cost is greater than average total cost, average total cost is rising. The margianal cost curve crosses the average total cost curve at it’s minimum. 1.

When the marginal cost is below the average cost it pulls the average cost down?

If the marginal cost of production is below the average cost for producing previous units, as it is for the points to the left of where MC crosses ATC, then producing one more additional unit will reduce average costs overall—and the ATC curve will be downward-sloping in this zone.

When average cost decreases marginal cost?

When the average cost declines, the marginal cost is less than the average cost. When the average cost increases, the marginal cost is greater than the average cost. When the average cost stays the same (is at a minimum or maximum), the marginal cost equals the average cost.

When marginal cost is less than average cost average cost?

Marginal cost is the change in total cost given a one unit change in output. Since the change in total cost is more than average​ cost, average cost will be pulled higher. Whenever marginal cost is less than average​ cost, average cost is falling.

Why does average cost curve and average variable cost curve never intersect each other?

The difference between the AC and AVC curve is the AFC curve. As the level of output increases the AFC becomes smaller and smaller. Accordingly, the difference between AC and AVC tends to diminish. However, it must be noted that as AFC is a rectangular hyperbola the two curves would never intersect each other.

Why does marginal cost equal average cost at its minimum?

The point of intersection between the MC and AC curves is also the minimum of the AC curve. This can be explained by the fact that when the cost of the marginal output is equal to the average cost of the output, then the AC neither falls nor rises (i.e. it reaches its minimum).

When price is below the minimum point of the average variable cost curve the firm?

If price is below the minimum average variable cost, the firm would lose less money by shuting down. In contrast, in scenario 3 the revenue that the center can earn is high enough that the losses diminish when it remains open, so the center should remain open in the short run.

Why does the marginal cost curve always intersect the average cost curve?

The marginal cost curve always intersects the average total cost curve at its lowest point because the marginal cost of making the next unit of output will always affect the average total cost. As a result, so long as marginal cost is less than average total cost, average total cost will fall.

What is the difference between marginal cost and average product?

Marginal cost (MC) is the extra cost incurred when one extra unit of output is produced. Average product (AC) is the total cost per unit of output. When the MC is smaller the AC, the AC decreases. This is because when the extra unit of output is cheaper than the average cost then the AC is pulled down.

What is the point of intersection between MC and AC curves?

The point of intersection between the MC and AC curves is also the minimum of the AC curve. This can be explained by the fact that when the cost of the marginal output is equal to the average cost of the output, then the AC neither falls nor rises (i.e. it reaches its minimum).

How do you calculate marginal cost?

Marginal cost can be calculated by getting the change in total cost when one unit is produced or added. The cost is also affected by the principle of variable proportions given that it is derived from variable costs. Its curve will drop briefly at the start before rising sharply.
