Résumé
Standard empirical tools for merger analysis assume price data, which may not be readily available. This paper characterizes sufficient conditions for identifying the unilateral effects of mergers without price data. I show that revenues, margins, and revenue diversion ratios are sufficient for identifying the gross upward pricing pressure indices, impact on consumer/producer surplus, and compensating marginal cost reductions associated with a merger. I also describe assumptions on demand that facilitate the identification of revenue diversion ratios and merger simulations. I use the proposed framework to evaluate the Staples/Office Depot merger (2016).
