Rebecca Haw Allensworth

David Daniels Allen Professor of Law

Rebecca Haw Allensworth studies antitrust and professional licensing. Her work on antitrust focuses on how to adapt competition policy to address competition problems posed by tech platforms and her research on professional licensing explores how lawmakers should balance the need for expertise in regulating the professions with the problems that can arise from self-regulation. She is currently writing Board to Death, a book about professional licensing and self-regulation. Her article about medical licensing boards and unethical prescribers, “Licensed to Pill,” appeared in The New York Review of Books in July 2020. Her work has been cited by the U.S. Supreme Court and has received the thirteenth annual Jerry S. Cohen Memorial Fund Writing Award for groundbreaking antitrust scholarship.

Professor Allensworth earned her undergraduate degree from Yale and an M.Phil. from Cambridge University before earning her J.D. at Harvard Law School, where she served as articles editor of the Harvard Law Review. She served as law clerk to Judge Richard A. Posner of the U.S. Court of Appeals for the Seventh Circuit and then as a Climenko Fellow at Harvard Law School before coming to Vanderbilt. She held the Tarkington Chair of Teaching Excellence before her appointment to a David Daniels Allen Chair in Law in 2022.

Allensworth teaches Contracts, Antitrust Law and an advanced antitrust course focused on Big Tech. She is a five-time winner of the Hall Hartman Outstanding Professor Award for excellence in teaching and was also selected by the class of 2019 to be their Commencement speaker.
