Abstract This paper covers the activities of the Economic Analysis Group of the

economic analysis undertaken by EAG in several important investigations and other
activities as an advocate for competition.
Keywords Antitrust · Competition policy · Mergers
The past year has been an active and exciting one for economists in the Economic
Analysis Group (EAG) of the Antitrust Division, U.S. Department of Justice (DOJ).
As in years past, a substantial share of their efforts were devoted to reviewing proposed
mergers and acquisitions. The economic analyses that were performed in several of
these are described in this article. In addition, EAG has been actively involved in a
variety of competition advocacy efforts, including the presentation of the Department
of Justice’s views in regulatory ﬁlings with sister agencies and in the preparation of
amicus briefs ﬁled with the Supreme Court. EAG economists also continue to provide
training, both domestically and in international settings, and to engage in substantial
individual research, the results of which are often presented at academic conferences
and/or published in academic journals and other publications.
The views contained herein are solely those of the authors and do not necessarily represent those of the
U.S. Department of Justice.
