Quantifying the Effects of Horizontal Mergers in European Competition Policy

Working Paper: CEPR ID: DP2697

Authors: Marc Ivaldi; Frank Verboven

Abstract: This Paper starts from a recent case studying how merger analysis in Europe may potentially be improved through simulation analysis. Starting from the product and geographic market definition in the Merger Decision, we formulate and estimate an oligopoly model with differentiated products. The model is simulated to account for the changed multiproduct ownership structure after the merger. We show how our first two tests, a potential and an actual market power test, produce useful information, complementary to the traditional dominance principle adopted in the European Union. A drastic revision of current merger principles is thus not required. We also show how simulation analysis can provide useful additional information that goes beyond the traditional dominance principle. This is illustrated through two examples. First, we analyse the effects of efficiencies through cost savings. Second, we compare alternative merger scenarios.
