Thus, a firm earning zero economic profits is still earning a normal or competitive return. Positive economic profits therefore indicate that a firm is earning more than the competitive norm. Economic profits are not the same as accounting profits. In accounting, profits are simply the excess of revenues over the explicit costs of obtaining the revenues. Costs are not calculated as opportunity costs and do not include a normal return on capital. Moreover, accountants calculate different categories of profits which may differ from country to country.

Key Takeaways In neoclassical economics, perfect competition is a theoretical market structure that produces the best possible economic outcomes for both consumers and society.

In the long-run, all of the possible causes of economic profits are eventually assumed away in the model of perfect competition.

In contrast, accounting profit is the difference between total revenue and explicit costs- it does not take opportunity costs into consideration, and is generally higher than economic profit. Economic profits may be positive, zero, or negative. If economic profit is positive, other firms have an incentive to enter the market. If profit is zero, other firms have no incentive to enter or exit. When economic profit is zero, a firm is earning the same as it would if its resources were employed in the next best alternative.
If the economic profit is negative, firms have the incentive to leave the market because their resources would be more profitable elsewhere. The amount of economic profit a firm earns is largely dependent on the degree of market competition and the time span under consideration. In competitive markets, where there are many firms and no single firm can affect the price of a good or service, economic profit can differ in the short-run and in the long-run.

Despite earning an economic profit of zero, the firm may still be earning a positive accounting profit. Long-Run Profit for Perfect Competition : In the long run for a firm in a competitive market, there is zero economic profit.
Graphically, this is seen at the intersection of the price level with the minimum point of the average total cost ATC curve.
