The DOJ/FTC Horizontal Merger Guidelines (HMGs) state that they

will calculate post-merger Herfindahl-Hirschmann Indices (HHI) and change in HHI caused by

the merger to determine if the merger deserves additional scrutiny from antitrust authorities (i.e.,

a Second Request). Describe other measures of market structure and techniques that United

States antitrust authorities could use to determine if a merger deserves additional scrutiny or may

lead to the antitrust authorities challenging the merger. Make sure you discuss the advantage and

disadvantages of each measure/technique, including using HHI. In this discussion, describe why

the Guidelines use HHI instead of some other measure of market structure or technique as a

starting point to determine if a merger deserves additional antitrust scrutiny (i.e. why is HHI

better than these other measures).
