Question

In the long run, the competitive firm's supply curve is the a. entire marginal-cost curve. b. portion of the marginal-cost curve that lies above the average-total-cost curve. c. upward-sloping portion of the average-total-cost curve. d. upward-sloping portion of the average-variable-cost curve. e. portion of the marginal-cost curve that lies above the average-variable-cost curve.

Answer 1

The long run will see the supply curve of a completive firm changing to the b. portion of the marginal-cost curve that lies above the average-total-cost curve.

What is the long-run supply curve in a perfect competition?

In a perfect competition, a company will only produce goods and services at a level where the marginal cost curve is above the average total cost in the long run.

This means that the supply curve will be the marginal cost curve but only the portion of this curve that is above the long-run average total cost curve.

The reason for this is that in the long-run., all the costs in a perfectly competitive firm are considered variable and so they can afford to avoid supply mishaps in the short term.

In conclusion, option B is correct.
