Lina Khan, the legal wunderkind who is reshaping the global debate over competition and corporate power. Her breakthrough came two years ago with “Amazon’s Antitrust Paradox”. Khan set out a simple but powerful argument: that it doesn’t matter if companies such as Amazon are making things cheaper in dollars if they are using predatory pricing strategies to dominate multiple industries and choke off competition and choice. Robert Hockett, a Cornell professor, has been impressed with Khan’s undogmatic approach to policy ideas. “She hasn’t been in an ivory tower for years.” If she and her contemporaries have their way, law — along with the economy and society at large — may be about to reach another dramatic turning point.
