Firms in a perfectly competitive market can make supernormal profits but only in the short run. Supernormal profit is made where average revenue exceeds average cost.
Why can’t firms make supernormal profit in long run?
In the long-run, profits and losses are eliminated because an infinite number of firms are producing infinitely-divisible, homogeneous products. Firms experience no barriers to entry, and all consumers have perfect information.
Is it possible for monopolistic firms to make supernormal profit Positive profit in long run?
Monopolies can maintain super-normal profits in the long run. As with all firms, profits are maximised when MC = MR. Given that price (AR) is above ATC at Q, supernormal profits are possible (area PABC).
Do oligopolies make supernormal profit?
However, if firms collude, they can agree to restrict industry supply to Q2, and increase the price to P2. This enables the industry to become more profitable. At Qc, firms made normal profit. But, if they can stick to their quotas and keep the price at P2, they make supernormal profit.
Can a firm in perfect competition earn supernormal profit?
It is impossible for a firm in perfect competition to earn supernormal profit in the long run, which is to say that a firm cannot make any more money than is necessary to cover its economic costs. If a firm is earning supernormal profit in the short term, this will act as a trigger for other firms to enter the market.
Can a monopoly firm earn Super Normal profit in the long run?
Hence, a monopoly firm can earn the supernormal profit in the long run as well as a short run because the seller has control over the prices to be fixed of the product and the entry of new firms is also restricted. Was this answer helpful?
Why are firms attracted to an industry with perfect competition?
In the short run Under perfect competition, firms can make super-normal profits or losses. However, in the long run firms are attracted into the industry if the incumbent firms are making supernormal profits. This is because there are no barriers to entry and because there is perfect knowledge.
How does competition affect the long run profit?
The arrival of new firms shifts the supply curve to the right, as shown in the diagram below, and pushes the price down. The lower price shifts the average revenue curve downwards until all the supernormal profit has been competed away and the firms are making just normal profits. This long-run equilibrium is shown in the diagram below.
