Topic:
Four Market Models
281.
Competitive firms are price takers largely because of intensive advertising by their
competitors.
282.
For a purely competitive firm, the demand curve facing it is the same as its marginal
revenue curve.
283.
In pure competition, the industry demand curve is infinitely price elastic.
284.
For an individual firm in pure competition, the firm‘s average revenue and marginal
revenue at any output level are both equal to the product’s price.
285.
If a purely competitive firm is producing a level of output greater than its profit-
maximizing output, then its profits must be negative.
286.
As long as its total revenues are greater than its total costs, a firm will earn positive
economic profits.
287.
If the firm produces an output level below its break-even point, then the firm will earn
negative economic profits.
288.
If a purely competitive firm is producing a level of output where the marginal revenue is
less than the marginal cost, then its profits must be negative.
289.
As long as an additional unit of output yields a marginal revenue larger than its marginal
cost, it will be adding to total profits of the firm.
290.
If MR > MC for a competitive firm, it should reduce its level of output in order to make
MR equal to MC.

291.
In the short run, a competitive firm will not produce unless price is at least equal to
average total costs.
292.
In the short run, fixed costs are important in determining a competitive firm‘s optimal level
of output.
293.
In pure competition, a competitive firm‘s supply curve is that section of its marginal cost
curve above ATC, and at any price below the average cost,
the firm will produce nothing.
