'For the Public Benefit' : Who Should Control Our Data?

We consider a platform that collects data from users. Data has commercial benefit to the platform, personal benefit to the user, and public benefit to other users. We ask whether the platform, or users, should have the right to decide which data the platform commercializes. We find that when users differ in their disutility from the commercialization of their data and the public benefit of data is high (low), it is welfare enhancing to let the platform (users) control the data.nIn contrast, when heterogeneity is in the disutility from the commercialization of different data items, it is welfare enhancing to let users (the platform) control the data when the public benefit of data is high (low). Furthermore, we find that allowing the platform to compensate users for their data is not always welfare enhancing and competition does not necessarily result in the efficient outcome
