What determines entry and exit of firms in a perfectly competitive industry in the long run?

What determines entry and exit of firms in a perfectly competitive industry in the long run?

In a perfectly competitive market in long-run equilibrium, an increase in demand creates economic profit in the short run and induces entry in the long run; a reduction in demand creates economic losses (negative economic profits) in the short run and forces some firms to exit the industry in the long run.

How do the entry and exit of firms in a perfectly competitive industry affect resource flows and long run economic profits and losses?

The entry and exit of firms in a purely competitive industry affect resource flows and long-run profits and losses. This entry and exit helps to improve resource allocation. Firms that exit an industry due to low profits release their resources to be used more profitably in other industries.

When the process of entry and exit has ended in a competitive market are firms profits positive negative or zero?

At the end of the process of entry and exit, firms that remain must be making zero economic profit. The process of entry and exit ends only when price and average total cost are driven to equality. Long-run equilibrium must have firms operating at their efficient scale.

How does entries and exits affect supply?

Entry of many new firms causes the market supply curve to shift to the right. As the supply curve shifts to the right, the market price starts decreasing, and with that, economic profits fall for new and existing firms. Exit of many firms causes the market supply curve to shift to the left.

What is free entry and exit?
