On the welfare effects of compatibility with Hotelling competition

Author

  • Paolo Bertoletti

Abstract

In a setting with Hotelling differentiation and (weak) network effects, when the market is already covered duopoly adoption of compatibility leads to anti-competitive effects and tends to be welfare excessive. We show that the latter result is reversed if the market is not assumed to be covered even under incompatibility (a condition which depends on the value of the intrinsic/stand-alone beneÂ…ts).
