DESCRIPTION:Thomas Philippon (New -York University)\, “Data Sharing and Mar
 ket Power with Two-Sided Platforms”\, Economics of Platforms Seminar\, Oct
 ober 5\, 2021\, 14:00–15:00\, Zoom Meeting.\n\nWe study an economy where c
 onsumers and merchants interact on a two-sided platform. The platform gath
 ers consumer data and sells it to merchants. Data sharing increases gains 
 from trade by improving match quality\, but also generates two externaliti
 es which increase the market power of the platform and lower merchant entr
 y. The gatekeeper externality arises from the platform’s control over acce
 ss to consumers. The copycat externality derives from its ability to compe
 te with its own merchants. These effects are not internalized by consumers
  and data sharing can be socially excessive. We study implications for the
  regulation of digital versus traditional platforms.
