Suppose a company creates its own differentiated type of sneaker and is thus considered a monopolistically competitive firm. This firm has a constant marginal cost curve. For each unit of output that the monopolistically competitive firm produces, it costs an additional $50. The firm's marginal revenue curve is MR=200−30Q, where Q is the quantity produced. The firm's perceived demand curve is P=200−15Q.
What is the monopolistically competitive firm's profit-maximizing output and price?
Suppose that you are a manager for a firm like EBC Brakes, which manufactures brakes for automobiles and motorcycles. Your company has two plants, one in the United States and the other in the United Kingdom. The following tables include estimated demand and marginal revenue for your brakes, along with the marginal costs at the two factories.

A friend has just started up her own business. Her firm asks you how much to charge for her product to maximize profits. The demand schedule for it is given by the first two columns in the table below; its total costs are given in the third column. For each level of output, you can calculate total revenue, marginal revenue, average cost, and marginal cost. The profit-maximizing level of output can be found at the point where TR - TC is greatest, or where MR = MC, (or the last quantity where MR is still greater than MC.)

- In the figure to the right, let D be the demand for a monopolistically competitive firm's output. Its marginal revenue is represented by MR. The firm's average cost of production is AC and its marginal cost of production is MC. A monopolistically competitive firm maximizes profit by producing the quantity where marginal cost (MC) equals marginal revenue (MR). Price is then set according to the demand curve (D), indicated by point maximum in the figure. The full-capacity average cost and quantity occur at the minimum point on the firm's average cost curve, indicated by @emclent in the figure A monopolistically competitive firm maximizes its profit where it is operating at less than full capacity or minimum efficient scale, which is the smallest quantity at which the average cost curve reaches its minimum (the bottom of a U-shaped average cost curve).
