Dynamic Privacy Choices
研究消费者隐私与平台数据收集的动态模型，分析平台承诺能力对隐私保护水平和消费者行为的影响，发现强承诺下平台逐步降低隐私保护，长期消费者隐私受损但活动水平高。
I study a dynamic model of consumer privacy and platform data collection. In each period consumers choose their level of platform activity. Greater activity generates more information about the consumer, thereby increasing platform profits. When the platform can commit to the future privacy policy, it collects information by committing to gradually decreasing the level of privacy protection. In the long run consumers lose privacy and receive low payoffs but choose high activity levels. In contrast, the platform with weaker commitment power may attain the commitment outcome or fail to collect any data depending on consumer expectations regarding future privacy protection.
