Indicative Price Rise with synergies

Author

Listed:
  • Voudon, Benoît

Abstract

This paper extends the evaluation of mergers’ unilateral effect on prices to incorporate the effect of variable cost synergies. The Indicative Price Rise metric was first introduced by Shapiro (1995), which allows to estimate the price increase caused by a merger based on pre-merger metrics such as prices, margins and diversion ratios. We derive the IPR formula including synergies for linear demand and isoelastic demand.
