Competition for attention in the Information (overload) Age
研究了信息过载时代多个行业如何竞争消费者注意力，发现广告水平在中等注意力水平时最高，整体广告过度但行业间分配最优，信息传输成本低且利润低的产品类别最应被指责。
The Information Age has a surfeit of information received relative to what is processed. We model multiple sectors competing for consumer attention, with competition in price within each sector. Sector advertising levels follow a constant elasticity of substitution (CES) form, and within‐sector prices are dispersed with a truncated Pareto distribution. The “information hump” shows highest ad levels for intermediate attention levels. Overall, advertising is excessive, although the allocation across sectors is optimal. The blame for information overload falls most on product categories with low information transmission costs and low profits .
