DESCRIPTION:Alexander Mackay (University of Virginia)\, “Vertical Integrati
 on and Consumer Choice: Evidence from a Field Experiment”\, Industrial Org
 anization seminar\, TSE\, May 4\, 2026\, 14:15–15:30\, room Auditorium 4.
 \n\nDigital platforms offer consumers vertically integrated products along
 side third-party alternatives. Using a field experiment that hides Amazon 
 brands\, we quantify the impacts of vertical integration—through both the 
 availability of private labels and their placement in search results. In t
 heir absence\, consumers choose similar products with no increase in searc
 h effort or cross-platform substitution. Yet some consumers prefer Amazon 
 brands\, and removing these products reduces consumer welfare by 5.5 perce
 nt. Contrary to concerns about self-preferencing\, demoting Amazon brands 
 in search results does not increase welfare\, as heterogeneous preferences
  make their prominent placement valuable to a meaningful share of consumer
 s.
