Chapter 9 - Monopolistic competition and oligopoly. In this chapter, the two market structures that fall between the extremes are discussed. Monopolistic competition contains a considerable amount of competition mixed with a small dose of monopoly power. Oligopoly, in contrast, implies a blend of greater monopoly power and less competition. | Monopolistic Competition and Oligopoly Chapter 9 McGraw-Hill/Irwin Copyright © 2014 by The McGraw-Hill Companies, Inc.

Monopolistic competition contains a considerable amount of competition mixed with a small dose of monopoly power. Oligopoly, in contrast, implies a blend of greater monopoly power and less competition. First, monopolistic competition is defined, listing important characteristics, typical examples, and efficiency outcomes. Next we turn to oligopoly, surveying the possible courses of price, output, and advertising behavior that oligopolistic industries might follow. Finally, oligopoly is assessed as to whether it is an efficient or inefficient market structure. Monopolistic Competition Relatively large number of sellers Differentiated products Easy entry and exit Advertising 9- In monopolistic competition, firms can differentiate their products by the product attributes, by service, with location, or with brand names and packaging. There is relatively easy entry and exit, just not as easy as with perfect competition. That is why the number of sellers is not as large as in perfect competition, but it is relatively large. This type of market experiences some pricing power due to the differentiated product. If a firm goes to the trouble and expense of differentiating their product, they should let people know about it. They can do this through advertising. Price and Output in Monopolistic Competition Demand is highly elastic Short-run profit or loss Produce where MR = MC Long-run normal profit Entry and exit Inefficient Product variety LO2 9- The firm’s demand curve is highly, but not perfectly, elastic. It is more elastic than the monopoly’s demand curve because the seller has many rivals producing close substitutes.
