Advertising Content
实证表明多数广告信息量少，甚至不标价格。本文分析垄断企业如何选择广告内容（产品信息、价格信息或两者），发现企业倾向于只提供有限产品信息，强制提供全部信息可能有害。
Empirical evidence suggests that most advertisements contain little direct information. Many do not mention prices. We analyze a monopoly firm's choice of advertising content and the information disclosed to consumers. The firm advertises only product information, price information, or both, and prefers to convey only limited product information if possible. It is socially harmful to force it to provide full information if it has sufficient ability to parse the information imparted, nor does it help to restrict the information voluntarily provided.
