Tax incidence under imperfect competition: Comment


  • Reny, Philip J.
  • Wilkie, Simon J.
  • Williams, Michael A.


Delipalla and O'Donnell (2001) contains a formula for the incidence of specific and ad valorem taxes in a conjectural variation oligopoly model with potentially asymmetric firms. The formula is incorrect. We derive the correct formula and provide a discussion of the error and its implications for empirical studies of pass-through.
