In the July 9 Washington Post article “Uber-Postmates merger will deliver only bad tidings for restaurants, consumers,” AAI President Diana Moss says 4-3 mergers can harm consumers. From the article:
“We know that 4-to-3 mergers are pernicious in the harm they cause to competition and consumers,” explained Diana Moss, president of the American Antitrust Institute. “And as an economist, I can tell you that there is no efficiency justification for this merger: Its only purpose is to enhance market power, eliminate a disruptive competitor and expand Uber’s ecosystem. It’s the perfect case to make a course correction in [the antitrust agencies] approach to platforms.”
