When the marginal unit costs more than the average, the average has to increase. By definition, then, the MC curve intersects the AVC curve at the minimum point on the AVC curve. At the intersection, MC and AVC are equal. If you flip the AVC and MC curves over, they become APL and MP curves.

What is the relationship between the average cost curve and the average variable cost curve?

The average total cost curve is typically U-shaped. Average variable cost (AVC) is calculated by dividing variable cost by the quantity produced. The average variable cost curve lies below the average total cost curve and is typically U-shaped or upward-sloping.

How does the marginal cost curve affect the average total cost curve?

The marginal cost curve represents how much more the next unit costs than the previous unit. As the costs of the next unit increase, they affect the average cost at that quantity, essentially flattening the curve when marginal cost is below average cost and pulling the curve up when marginal cost is above average cost.

What shifts the MC curve?

Shifting Cost Curves: Changing a variable cost like per unit taxes or subsidies, labor costs or raw material costs will shift the ATC, AVC, and MC upward if it is a cost increase or downward if it is a cost decrease.

Can AC fall when MC is rising?

Yes, AC can fall, when MC is rising. However, it is possible only when MC is less than AC. It means that as long as MC curve is below the AC curve, AC will fall even if MC is rising.

At what output is MC at the minimum?

9
The minimum of AVC always occurs where AVC = MC. At what quantity of output is marginal cost at its minimum? MC attains a minimum at an output of 9.

What is the relationship between average cost and marginal cost?

The various points of relationship between average cost and marginal cost are given below: Both average cost and marginal cost are derived from total cost. Average cost is obtained by dividing total cost by the number of units produced. Marginal cost is the cost of producing one additional unit of output.

What causes a rise in the cost curve?

This leads to a rise in the average cost curve, when the marginal cost is more than the average cost. Finally, if the additional unit of output produced costs same as the average cost incurred on the previous units, the overall average cost does not change and attains its minimum value.

When does the marginal cost curve slope upward?

Once diminishing marginal products is reached, the marginal cost of producing each additional unit will be greater than the marginal cost of the previous unit. In other words, the marginal cost curve for most production processes will eventually slope upward, as shown here. Shape of Average Cost Curves  Jodi Beggs

When does MC lie above the average cost curve?

When marginal cost curve MC lies above the average cost curve AC, the latter is rising. At the point of intersec­tion L where MC is equal to AC, AC is neither falling nor rising, that is, at point L, AC has just ceased to fall but has not yet begun to rise.
