The Critical Role of Price and Marginal Cost In the long run equilibrium, the firm operates on the perfectly elastic portion of its long-run average cost curve, where minimum efficient scale is achieved. In the neoclassical economic model, perfect competition represents a theoretical benchmark where no single participant can influence the market price, and all actors operate with perfect information.
Long Run Equilibrium Zero Economic Profit: Firms Covering All Costs
P = ATC Price equals Average Total Cost Total revenue covers all costs, resulting in zero economic profit. The assumption of free entry and exit means that new firms can easily enter the industry, increasing market supply.
This market price is then taken as given by the individual firm. Productive and Allocative Efficiency.
Achieving Zero Economic Profit in Long Run Equilibrium
At this point, the firm is covering all explicit costs, such as wages and materials, as well as implicit costs, like the return an owner could have earned by investing their capital elsewhere. Conversely, if firms are experiencing losses, some will exit the market, reducing supply and allowing the price to rise.
