内容简介:

Prior studies suggest that platform owners’ appropriate use of information disclosure can enhance user engagement and facilitate market exchanges. Disclosure of personal information, however, introduces privacy concerns related to its identifiability. This study examines how the identifiability of personal information (deidentified vs. identifiable) disclosed by a platform affects users’ engagement with sellers. To identify the causal effect, we ran a randomized field experiment on a major online marketplace with two app interfaces identical except for their information‐disclosure settings. We find that disclosure of deidentified personal information enhances user engagement—more clicks, product views, and seller views—compared to those exposed to fully identifiable information. This positive effect is amplified for dual-role users who also sell on the platform, particularly those selling personal products. Our study has important implications for platform owners to manage the identifiability of users’ personal information and highlights the need for privacy management to consider users’ dual roles as both buyers and sellers.
