The consumer welfare standard (CWS) has been a staple in antitrust analysis for the better part of 40 years, surviving relatively unharmed through both Democratic and Republican administrations over its lifetime. A shift has occurred in the past few years, and when reflecting on the ABA Antitrust Spring Meeting last week I realize that the days of a wholesale defense of the CWS are likely behind us.
In an attempt to correct this mistake, I have focused this month on pushing back against detractors of the consumer welfare standard. First, I kindly put forth edits to the recent letter from the Antitrust Division to the Judiciary Committee Leadership, supporting proposed antitrust legislation. Next, I lay out a path forward for thinking about the CWS in a dynamic economy and defend the CWS in a pair of responses in ProMarket and the Wall Street Journal. Finally, Andrew Mercado and Christopher Kaiser discuss why monopoly fears in the economy are overblown and why there is no cause for alarm.
