Normal profit in perfect competition In perfect competition, there is freedom of entry and exit. If the industry was making supernormal profit, then new firms would enter the market until normal profits were made. This is why normal profits will be made in the long run.
Does perfect competition make profit in the long-run?
Firms in a perfectly competitive world earn zero profit in the long-run. While firms can earn accounting profits in the long-run, they cannot earn economic profits.
Why will perfectly competitive firms make zero profits in the long-run how are normal profits related to economic profits?
The existence of economic profits attracts entry, economic losses lead to exit, and in long-run equilibrium, firms in a perfectly competitive industry will earn zero economic profit. It will induce entry or exit in the long run so that price will change by enough to leave firms earning zero economic profit.
Why can a firm under perfect competition not earn abnormal profits in the long-run?
Under perfect competition, no firm can earn abnormal profits in the long run. This is because if any firm in the long run earns abnormal profits (that is price > minimum of average cost curve), then new firms are attracted into the market.
Does a monopolist firm always earn abnormal profit?
Yes. A monopoly firm can make abnormal profits in the long run because of lack of freedom of entry and exit of firms in the market. Due to freedom of entry and exit of firms under monopolistic competition, a firm cannot earn abnormal profits in the long run.
When should a perfectly competitive firm shut down?
Looking at Table 6, if the price falls below $2.05, the minimum average variable cost, the firm must shut down. The intersection of the average variable cost curve and the marginal cost curve, which shows the price where the firm would lack enough revenue to cover its variable costs, is called the shutdown point.
