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. It is within this long-run framework that the relationship between price, cost, and production efficiency reaches its most definitive and instructive form.
Understanding Price Taker Firm Long Run Competitive Equilibrium and Zero Economic Profit
The assumption of free entry and exit means that new firms can easily enter the industry, increasing market supply. P = min LRAC Price equals minimum Long-Run Average Cost The firm is producing at the lowest possible average cost, achieving productive efficiency.
P = MC Price equals Marginal Cost The profit-maximizing output level is achieved. For the firm to be in equilibrium, it must produce the quantity of output where its marginal cost is exactly equal to this market price.
Long Run Competitive Equilibrium: Price Taker Firm at Minimum LRAC and Zero Economic Profit
Because the firm is a price taker, the market price is determined by the intersection of industry supply and demand. P = ATC Price equals Average Total Cost Total revenue covers all costs, resulting in zero economic profit.
