You are hired as the consultant to a monopolistically � competitive firm. The firm reports the following � information about its price, marginal cost, and � average total cost. Can the firm possibly be � maximizing profit? If not, what should it do to � increase profit? If the firm is profit maximizing, is � the firm in a long-run equilibrium? If not, what will� happen to restore long-run equilibrium?
To determine if the firm is maximizing profit, you need to compare its price (P) to its marginal cost (MC) and average total cost (ATC).
If P > MC, the firm can increase its profit by producing and selling more output. In this case, the firm can increase its production level until MC = P to maximize profit.
If P < MC, the firm is producing at a quantity where production costs exceed revenues. To maximize profit, the firm should decrease its output level until MC = P.
If P = MC, the firm is already maximizing profit at the given quantity level.
To determine if the firm is in long-run equilibrium, you need to consider its average total cost (ATC) in relation to the market price.
If the market price is higher than the ATC, the firm is earning positive economic profits in the short run. Other firms may enter the market attracted by these profits, causing an increase in market supply. This increased supply will eventually drive down the market price until it is equal to the ATC of each firm. At this point, the firm will not earn economic profit, but will earn zero economic profit, which is considered a long-run equilibrium for a monopolistically competitive firm.
If the market price is below the ATC, the firm is experiencing losses. In the long run, firms will exit the market due to these losses, causing a decrease in market supply. This decrease in supply will eventually drive up the market price to a level equal to the ATC, restoring long-run equilibrium.
Therefore, if the firm is not maximizing profit, it should adjust its output level to align with MC = P. If the firm is not in long-run equilibrium, market forces will work to restore equilibrium by adjusting the market price.
