Why do firms make supernormal profit in the short run in perfect competition?
Suppose there is a rise in demand, price rises and a firm can make supernormal profit in the short-term. Because there are no barriers to entry, firms will be encouraged to enter the market until price falls back down to P1 and normal profits are made.
Is there supernormal profit in perfect competition?
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.
How can perfect competition make profits in the short run?
In order to maximize profits in a perfectly competitive market, firms set marginal revenue equal to marginal cost (MR=MC). MR is the slope of the revenue curve, which is also equal to the demand curve (D) and price (P). In the short-term, it is possible for economic profits to be positive, zero, or negative.
What is short run in perfect competition?
The short-run (SR) supply curve for a perfectly competitive firm is the marginal cost (MC) curve at and above the shutdown point. Portions of the marginal cost curve below the shutdown point are not part of the SR supply curve because the firm is not producing any positive quantity in that range.
What is meant by supernormal profit?
In economics, abnormal profit, also called excess profit, supernormal profit or pure profit, is “profit of a firm over and above what provides its owners with a normal (market equilibrium) return to capital.” Normal profit (return) in turn is defined as opportunity cost of the owner’s resources.
In which condition under perfect competition would a firm maximize profit in the short run?
The profit-maximizing choice for a perfectly competitive firm will occur at the level of output where marginal revenue is equal to marginal cost—that is, where MR = MC. This occurs at Q = 80 in the figure.
Do monopoly firms get a normal profit or supernormal profit in the short run explain how?
In the short run, firms in competitive markets and monopolies could make supernormal profit. Therefore, in the long-run in competitive markets, prices will fall and profits will fall. However in the long-run in monopoly prices and profits can remain high.
Why will supernormal profits fall in the long run?
This is because, although in the short run, one firm may create a technical advantage and reduce it’s costs (creating supernormal profit), in the long run, because of the perfect information, every single firm will be able to copy the first firm and everyone’s total costs will fall but will be the same as eachother’s.

What is meant by abnormal profit?
Abnormal profit means there is an incentive for other firms to enter the industry. (if they can) When the price is P3, the firm makes supernormal profit. This is because at P3, Average revenue is greater than average total cost. (ATC) The theory of perfect competition suggests that supernormal profit can only be earned in the short term.
