We know that digital platforms can be very powerful, but how does their use of data relate to power?
In three ways that derive from the datafication and digitisation affordances of platforms:
- Addressing Information Failure. Platforms succeed in part by finding ways to overcome information failures in existing markets. These failures may be sources of power for incumbents. For example, estate agents (realtors) hold power in real estate markets due to information asymmetries; such as knowledge of house sale prices. Real estate platforms put such data into the public domain, thus undermining the power of incumbents. Information failures may also be a source of weakness in existing markets. For example, riders with traditional taxi firms don’t know exactly when their cab will arrive. Platforms provide such data and so, again, undermine incumbents.
- Mashing Up. As they deal with digitised data, platforms can gain power by integrating different data streams onto the platform. Real estate platforms integrate online information about neighbourhoods. Ride-hailing platforms integrate online maps to show cab location and routes to riders and drivers.
- Controlling New Data. By digitising transactions and associated processes, platforms create, capture and control new data. This bolsters their power; typically by creating new information asymmetries: the platforms know things that others don’t. Real estate platforms can monitor search behaviours of buyers to understand more about which features of house listings they value most. Ride-hailing platforms understand spatio-temporal patterns of supply and demand alongside many other behavioural characteristics of riders and drivers.
This simple framework can usefully be applied in order to analyse the role of data in platforms, and its contribution to power.Follow @CDIManchester
