Privacy as a Public Good: A Case for Electronic Cash
研究了支付隐私减少的福利影响，指出个人不保护支付隐私会降低社会福利，并讨论了电子现金等补救措施。
Privacy is a feature inherent to the use of cash. With steadily increasing market shares of digital payment platforms, privacy in payments may no longer be attainable in the future. We explore the potential welfare impacts of reductions in privacy in payments. In our framework, firms may use data collected through payments to price discriminate future consumers. A public good aspect arises because individuals do not internalize the full cost of failing to protect their privacy and reduce social welfare by suboptimally choosing not to protect their privacy in payments. We discuss potential remedies, including the issuance of electronic cash.
