PayTech and the D(ata) N(etwork) A(ctivities) of BigTech Platforms

Why do BigTech platforms introduce payment services? Digital platforms often run business models where activities on the platform generate data that can be monetized off the platform. There is a trade-off between the value of such data and the privacy concerns of users, since platforms need to compensate users for their privacy loss by subsidizing  activities. The  nature  of  complementarities  between  data  and payments determines whether and how payment services are provided. When data help to provide better payments (data-driven payments), platforms have too little incentive to adopt. When payments generate additional data (payments-driven data), platforms may adopt payments inefficiently.
