Shifts in Privacy Concerns
利用八年间超过三百万份在线营销调查数据，研究发现消费者拒绝透露收入的比例随时间上升，且老年人与年轻人的差距在扩大，部分原因是人们对隐私相关情境的认知在拓宽。
This paper explores how digitization and the associated use of customer data have affected the evolution of consumer privacy concerns. We measure privacy concerns by reluctance to disclose income in an online marketing research survey. Using over three million responses over eight years, our data show: (1) Refusals to reveal information have risen over time, (2) Older people are less likely to reveal information, and (3) The difference between older and younger people has increased over time. Our results suggest that the trends over time are partly due to broadening perceptions of the contexts in which privacy is relevant.
