Network Externality and Commercial Software Piracy


  • Sougata Poddar

    () (Department of Economics, National University of Singapore)


Contrary to the earlier findings under end-users piracy where the existence of strong network externality was shown to be a reason for allowing limited piracy, we find when the piracy is commercial in nature the optimal policy for the original software developer is to protect its product irrespective of the strength of network externality in the software users market.
