注意力经济模型：数据、平台与发现
A Model of the Attention Economy: Data, Platforms, and Discovery
摘要
This paper develops a dynamic model of the attention economy featuring two interlinked markets: a product market, where consumers have limited awareness of firms, and an attention market, where platforms attract attention by investing in free services (e.g., social media, streaming, podcasts) and sell targeted ads using data on consumer preferences. The model provides a tractable framework in which platform investment, ad-driven discovery, product demand, and ad revenue are jointly determined. The effects of data and interoperability policies can reverse over time, platform quality may be inefficiently high or low, and the rise of data-rich digital advertising can coincide with a declining ad revenue-to-GDP ratio.
中文摘要
本文构建了一个注意力经济的动态模型，该模型包含两个相互关联的市场：产品市场（消费者对企业的认知有限）和注意力市场（平台通过投资免费服务（如社交媒体、流媒体、播客）吸引注意力，并利用消费者偏好数据销售定向广告）。该模型提供了一个易于处理的框架，其中平台投资、广告驱动的发现、产品需求和广告收入是共同决定的。数据与互操作性政策的效果可能随时间逆转，平台质量可能处于低效的高或低水平，而数据丰富的数字广告的兴起可能与广告收入占GDP比重的下降同时发生。
