Advertising is a powerful tool for consumers.
Calfee shows how advertising brings consumers information they would otherwise not get. Consumers find out about better prices, higher quality, and ways to improve their lives. For example, advertising from drug companies about allergies, cholesterol, and high blood pressure leads consumers to get needed health care. Advertising corrects flaws in the marketplace. Advertisers often tell consumers what's wrong with competitors' products and services, creating demand for better ones.
