Re: Jonathan Barnett
Jonathan Barnett wrote an op-ed piece, based on his forthcoming paper to be published in the University of Chicago Business Law Review, about antitrust regulations and the effects it has on merger review processes. "This inquiry raises serious concerns that legislators and regulators have embarked on a course of action that has an insufficient factual foundation in the digital markets on which competition policymakers have focused," Barnett wrote.
