Describe and explain a perfectly competitive firm's short-run supply curve.

What will be an ideal response?


A perfectly competitive firm's short-run supply curve is the portion of its marginal cost curve that lies above the minimum of its average variable cost curve. A profit-maximizing firm will always produce a quantity such that price is equal to marginal cost, provided that the price of the product is high enough so that it can cover its variable costs and at least part of its fixed costs. This means that price must exceed the minimum of average variable cost. Thus, by using the part of the marginal cost curve that lies above the minimum of average variable cost, we can determine the quantity that a firm will produce at every given price. This is precisely what the firm's supply curve is.
