- PublicationCoordination in markets with consumption externalities : the role of advertising and product qualityThis paper studies advertising in vertically differentiated product markets with positive consumption externalities. In markets with consumption externalities, the value of the product to the consumer depends on the purchasing decisions of other consumers. In such markets, we show that firms will engage in advertising competition in order to convince consumers of their popularity only as long as they produce goods of similar quality. The firm with the lower quality product will have a greater incentive to advertise. If it is not the brand to provide the greater consumption externality it will have very low market share due to its low intrinsic quality. Hence, in equilibrium, the lower quality product will often be more popular. This provides an additional explanation for the empirical observation that in some markets high quality is associated with lower levels of advertising.
179 - PublicationConsumption externalities, coordination and advertisingThe aim of this Paper is to demonstrate that advertising can have an important function in markets with consumption externalities, apart from its persuasive and informative roles. We show that advertising may function as a device to coordinate consumer expectations of the purchasing decisions of other consumers in markets with consumption externalities. The implications of advertising as a coordinating device are examined in the pricing and advertising decisions of firms interacting strategically. While, at times, the one period advertising expense can exceed the one period monopoly profit, in equilibrium consumers will pay a premium for the more heavily advertised brand.
