摘要

本文讨论了大技术与数据隐私。首先，我们展示了自千禧年以来科技公司的迅速崛起。以Facebook为例(2022年最受欢迎的社交网络)，我们展示了它对个人身份数据收集和广告的依赖。其次，我们调查剑桥分析公司的数据泄露事件。我们使用事件研究方法表明，股票价格会因数据泄露而下跌。事件窗口期累计异常收益下降约9.8%。第三，我们讨论了应对数据隐私问题的政策选择。GDPR为保护个人可识别数据提供了立法模式。

Big technology and data privacy

This paper discusses big technology and data privacy. First, we show the rapid rise in technology firms since the millennium. Using Facebook as a case study (the most popular social network in 2022), we show its reliance on personally identifiable data collection and advertising. Second, we investigate the Cambridge Analytica data breach. We show that stock prices fall in response to the data breach using event study methods. Cumulative abnormal returns decline by about 9.8% in the event window. Third, we discuss policy options in response to data privacy concerns. The GDPR provides a legislative model for protecting individually identifiable data.
