DESCRIPTION:Paul Heidhues (Dusseldorf Institute for Competition Economics)\
 , “A Theory of Digital Ecosystems”\, Economics of Platforms Seminar\, Octo
 ber 1\, 2024\, 14:00–15:00\, Zoom Meeting.\n\nWe develop a model of digita
 l ecosystems based on the assumption that a multimarket firm can use a sal
 e in or data from one market to steer users toward its products\nin other 
 markets. Due to this “cross-market leverage\,” a market leader at an “acce
 ss\npoint” (where users begin their online journeys) has a high value from
  offering services in connected markets (where users continue their journe
 ys)\, and can thus make\nprofitable takeovers. Indeed\, because the firm h
 as the threatening outside option of\nacquiring\, and steering users towar
 d\, its target’s competitor\, it can take over the target at a discount. I
 n contrast\, other firms have no or smaller incentives for takeovers\,\nex
 plaining why ecosystems grow out of market leaders at access points. Conve
 rsely\,\ncross-market leverage also implies that once an ecosystem has gro
 wn\, it has an increased value of controlling access points\, so it may go
  to great lengths to dominate\nthese markets.\nOur theory’s logic suggests
  that ecosystems have mixed implications for consumer\nwelfare. Under plau
 sible assumptions\, a to-be ecosystem takes over market leaders\,\nand thi
 s consolidation of good services across markets benefits consumers in the 
 short\nrun. But an ecosystem’s takeovers and dominance of access points lo
 wer incentives for\nentry and innovation\, and lower the efficiency of acc
 ess-point markets with superior\nalternatives. Hence\, the long-run welfar
 e implications of ecosystem growth are often\nnegative.
