LONG-RUN EQUILIBRIUM, MONOPOLISTIC COMPETITION: Relative freedom of entry and exit ensures that, in the long run, every firm in a monopolistically competitive industry earns exactly a normal profit, receiving neither an economic profit, nor incurring an economic loss. This result is achieved because entry and exit affects the market supply curve, which affects the overall market price, each firm's demand curve, and the range or prices it can charge. Each firm's demand curve adjusts until the profit-maximizing price is exactly equal to average total cost (both short run and long run).

MARGINAL COST AND LAW OF DIMINISHING MARGINAL RETURNS Decreasing then increasing marginal cost, reflected by a U-shaped marginal cost curve, is the result of increasing then decreasing marginal returns. In particular the decreasing marginal returns is caused by the law of diminishing marginal returns. As such, the law of diminishing marginal returns affects not only the short-run production of a firm but also the cost of short-run production. This translates into a positively-sloped supply curve for profit-maximizing competitive firms.
