In the realm of microeconomics, perfect competition serves as an idealized model characterized by a large number of small firms, homogeneous products, free entry and exit from the market, and perfect information among market participants. This model plays a significant role in understanding market dynamics, especially the long-term equilibrium conditions where firms tend to earn zero economic profits. The phenomenon that results in zero economic profits or losses over the long run in perfect competition can be explained through the principles of economic theory, particularly the concepts of free market entry and exit, profit maximization, and the role of economic profits as signals for resource allocation.

At the core of perfect competition is the assumption of free entry and exit, which ensures that firms can enter a market when they observe profits and exit when they face losses (Mankiw, 2021). This entry and exit mechanism is central to the long-term equilibrium state where firms in a perfectly competitive market earn zero economic profits. When existing firms are earning positive economic profits, new entrants are attracted to the market because there are no barriers preventing their entry. The influx of firms increases the supply of the good, leading to a downward pressure on market prices (Demsetz, 2020). As prices decrease, individual firms see their profits diminish until they reach the point where price equals the minimum of their average total cost (ATC). At this point, firms are neither earning excess profits that would attract new entrants nor incurring losses that would compel them to leave the market.

Conversely, if firms experience economic losses—where price falls below average total costs—firms will exit the industry, reducing the supply of the product. This reduction causes an upward pressure on market prices until remaining firms can cover their average total costs, restoring the zero-profit equilibrium (Sloman, 2018). This dynamic adjustment process illustrates how the free movement of firms in and out of the industry ensures that, in the long run, economic profits are eliminated. Firms operate at their most efficient scale—the point where marginal cost (MC) equals marginal revenue (MR)—and their price equals the minimum of the ATC curve.

Moreover, the nature of perfect competition implies that firms are price takers; they have no power to influence the market price and must accept the prevailing market price determined by aggregate supply and demand (Pindyck & Rubinfeld, 2018). This characteristic reinforces the tendency for profits or losses to be eliminated in the long run because individual firms' output decisions do not impact the market price. Instead, market forces drive the economic environment toward a state of normal profit, where firms cover their opportunity costs but do not earn excess profits that could attract new entrants.

The elimination of economic profits in the long run under perfect competition can also be supported by empirical research. For instance, investigations into highly competitive markets such as agricultural industries show that, over time, prices tend to stabilize around the level that covers average costs, reflecting a long-run equilibrium state (Cook, 2019). These observations validate the theoretical prediction that perfect competition leads to zero economic profits in the long run, as the market self-curates through entry and exit mechanisms, balancing supply and demand.

In conclusion, perfect competition inherently discourages the persistence of economic profits or losses in the long run due to free entry and exit, firms operating at their most efficient scale, and competitive market forces. The continuous process of market entry when profits are above normal and exit when profits are below normal cements the tendency toward a balanced state where firms earn only normal profits, covering opportunity costs but earning no excess return. This equilibrium underscores the efficiency of perfect competition as a benchmark for ideal market performance, even though real-world markets rarely conform perfectly to this model.
