Who Is the Dominant Actor Under the US Merger Regulation?

The US appears to lean towards the model of unconcentrated and distributed competition regulation agencies, instead of a single concentrated one. Aside from the states and private litigants, in practice, this model mainly runs through the Department of Justice (DOJ), via its Antitrust Division, and the Federal Trade Commission (FTC)’s enforcement. Traditionally, under developments of the regulatory approach, the ‘quasi-judicial’ FTC could be understood to be a cornerstone of US antitrust law, particularly in its practical enforcement. However, it appears that the DOJ contributes far more policies on the specific regulation of mergers as well as consumption of merger remedies. By analysing the US model of ‘inter-agency competition’ under perspectives of merger control, this writing leads to proof that the DOJ is a dominant actor to some extent. More significantly, the DOJ’s performances partially bring the FTC and others to the uniformity of stipulated mergers as well as approved remedy fashions.
