On September 24, 2019, AAI President Diana Moss testified on the issue of acquisitions of nascent or potential competitors by digital platforms. Moss summarized recent research by AAI on the record of weak merger enforcement in the digital technology sector and explained the possible reasons for it. Her testimony outlines a plan for invigorating merger enforcement for the benefit of competition, consumers, and innovation, including stronger merger presumptions and the need for merger retrospectives and enhanced agency transparency. Moss also suggests a blue ribbon panel to evaluate the need for and scope of a potential oversight authority for the digital technology sector.
