MAPP has participated in many merger proceedings before the European Commission and national competition authorities, in sectors including publishing, television, building materials, retailing, mining, transportation, energy and professional services.

Our contributions cover the entire range of issues raised in merger cases, namely:

  • market delineation;

  • coordinated effects;

  • non-coordinated effects;

  • vertical and conglomeral effects;

  • the likelihood of merger-specific efficiencies and the extent of their passing on to final consumers.

We also provide assistance for the design of remedy packages aiming to solve competition authorities' concerns.

In the course of their academic and consulting activities, our economists have developed a broad expertise that is of direct relevance to merger control:

  • Antoine Chapsal is the author of a seminal contribution on the delineation of geographic markets based on the 'hypothetical consumer method'. His proposed approach is gaining ground with competition authorities because it allows for a calculation of market shares that reflects competitive constraints more accurately than traditional methods.

  • Philippe Février’s specialization in auction theory and in quantitative microeconomics allows us to implement sophisticated econometric techniques that cast light on the functioning of competition in the markets under scrutiny. His experience in conducting merger simulations is of particular relevance, since it makes it possible to estimate the impact of a merger on prices and market shares, taking into account the possible efficiency gains. The merger simulation technique is also well suited to the comparison of alternative divestiture scenarios.

  • Anne Perrot has been working for many years on the various economic aspects of the competitive assessment of mergers, as an academic, in her capacity of Vice Chair of the French Competition Authority, and in the context of the International Competition Network.

  • David Spector is the author of many articles on the economics of mergers, on subjects including efficiency defenses, buyer power, the impact of potential entry on the likelihood of non-coordinated effects, and the proper application of the Airtours criteria to the assessment of coordinated effects. As a non-governmental advisor to the French Competition Authority, he regularly participates to the work of the International Competition Network on this subject.

These competencies allow us to address the entire range of economic issues that may be raised in merger proceedings, using a complete theoretical and quantitative toolkit.
