Why doesn't a monopolistically competitive firm produce where \(P=M C\), as a perfectly competitive firm does?
7-Eleven, Inc., operates more than 20,000 convenience stores worldwide. Edward Moneypenny, 7 -Eleven's chief financial officer, was asked to name the biggest risk the company faced. He replied, "I would say that the biggest risk that 7 -Eleven faces, like all retailers, is competition ... because that is something that you've got to be aware of in this business." In what sense is competition a "risk" to a business? Why would a company in the retail business need to be particularly aware of competition?
A student makes the following comment: I can understand why a perfectly competitive firm won't earn a profit in the long run because it charges a price equal to marginal cost. But a monopolistically competitive firm can charge a price greater than marginal cost, so why can't it continue to earn a profit in the long run?
(Related to the Don't Let This Happen to You on page 458) A student remarks: If firms in a monopolistically competitive industry are earning an economic profit, new firms will enter the industry. Eventually, a representative firm will find that its demand curve has shifted to the left until it is just tangent to its average total cost curve and the firm is earning zero profit. Because firms are earning zero profit at that point, some firms will leave the industry, and the representative firm will find that its demand curve will shift to the right. In long-run equilibrium, price will be above average total cost by just enough so that each firm is just breaking even. Briefly explain whether you agree with this analysis.
Is it possible for marginal revenue to be negative for a firm selling in a perfectly competitive market? Is it possible for marginal revenue to be negative for a firm selling in a monopolistically competitive market? Briefly explain.
