Exclusionary Pricing and Rebates When Scale Matters

  • Karlinger, Liliane
  • Motta, Massimo

We consider an incumbent firm and a more efficient entrant, both offering a network good to several asymmetric buyers. The incumbent disposes of an installed base, while the entrant has a network of size zero at the outset, and needs to attract a critical mass of buyers to operate. We analyze different price schemes (uniform pricing, implicit price discrimination - or rebates, explicit price discrimination) and show that the schemes which - for given market structure - induce a higher level of welfare are also those under which the incumbent is more likely to exclude the rival.
