The supply curve for each firm is simply its marginal cost MC curve above the minimum point on the average variable cost AVC curve. Carrying on, what about the items that dictate and influence long run decision making? Forces in a competitive industry ensure that firms earn zero economic profits in the long-run.

Competitive industries will adjust in two ways: Entry and exit, 2. Changes in plant size Entry and Exit: The prospect of persistent profit of loss causes firms to enter or exit an industry. If firms are making economic profits, other firms enter the industry. This graph shows how where there is room for new entrants in the market and how it eliminates industry profits in the long run.

If firms are making economic losses, some of the existing firms exit the industry. This entry and exit of firms influences prices, quantities, and economic profits. This graph depicts economic losses in the industry. As firms leave an industry, the price rises and the economic loss of each remaining firm decreases.

When a firm changes its plant size, it can lower its costs and increase its economic profit. Therefore, in the long-run equilibrium for a competitive industry, all firms must be: Unable to increase profits by altering its scale of operations. And that concludes our intro into profit maximization and shut down points for firms.Class 12 Economics Notes.
