Relationship between Marginal Product and Total Product When the Marginal Product (MP) increases, the Total Product is also increasing at an increasing rate. This gives the Total product curve a convex shape in the beginning as variable factor inputs increase.

How does total product behave when MP rises?

Answer: Average Product increases as long as Marginal Product (MP) > Average Product (AP). Alternatively, when MP > AP, AP rises. Average Product is maximum and constant when Average Product (AP) = Marginal Product (MP).

Why does marginal cost increase as output increases?

Marginal Cost is the increase in cost caused by producing one more unit of the good. The Marginal Cost curve is U shaped because initially when a firm increases its output, total costs, as well as variable costs, start to increase at a diminishing rate. Then as output rises, the marginal cost increases.

What is called the increment of output from a one unit increase in the capital stock holding all other factors of production constant?

In economics, diminishing returns is the decrease in marginal (incremental) output of a production process as the amount of a single factor of production is incrementally increased, holding all other factors of production equal (ceteris paribus).

When the average product is rising?

If marginal product is less than average product, then average product declines. If marginal product is greater than average product, then average product rises. If marginal product is equal to average product, then average product does not change.

What is the slope of the total product curve?

The slope of a total product curve for any variable factor is a measure of the change in output associated with a change in the amount of the variable factor, with the quantities of all other factors held constant.

Why marginal cost is supply curve?

The marginal cost curve is a supply curve only because a perfectly competitive firm equates price with marginal cost. This happens only because price is equal to marginal revenue for a perfectly competitive firm. As such, the marginal cost curve is NOT the firm’s supply curve.

How do Increases in technology affect the aggregate production function?

How do increases in technology affect the aggregate production​ function? With increases in​ technology, the aggregate production function shifts​ up, indicating more output is produced from the same amount of inputs.

What happens when total product is increasing at a decreasing rate?

When total product is increasing at a decreasing rate, the total cost is increasing at an increasing rate.

Which cost increases continuously with increases in output?

Variable cost increases continuously with the increase in production.

What is the slope of total cost?

The slope of the total cost curve (and total variable cost curve) is marginal cost. As such, if the total cost curve has a positive slope (that is, is upward sloping), then marginal cost is positive.
