Pop Up GLOSS*arama: SHORT-RUN SUPPLY CURVE, MONOPOLISTIC COMPETITION

SHORT-RUN SUPPLY CURVE, MONOPOLISTIC COMPETITION: Market control by a monopolistically competitive firm means that it does not have a supply relation between the quantity of output produced and the price. By way of comparison a perfectly competitive firm DOES have a short-run supply curve. The small amount of market control by a monopolistically competitive firm means that its' price is NOT equal to marginal revenue, and thus it does NOT equate marginal cost and price. As such, a monopolistically competitive firm does not move along it's marginal cost curve. A monopolistic competition does not necessarily supply larger quantities at higher prices or smaller quantities at lower prices.
