Should you need a license for that? For law professor and antitrust expert Rebecca Haw Allensworth, there are huge problems with professional licensing in America—and her solutions might not make anyone completely happy.

 In her new book, The Licensing Racket: How We Decide Who Is Allowed to Work, and Why It Goes Wrong, Allensworth takes a deep dive into the history and function of licensing in the United States. While licensing boards are put forth as a way to protect consumers, Allensworth says that in practice, their decisions can be arbitrary and their disciplinary functions flawed.

In this episode of the Modern Law Library, Allensworth and the ABA Journal’s Lee Rawles chat about a range of professions that currently require licenses, from hairdressing to law and medicine. While disciplinary procedures for lawyers are not open to the public, she was able to attend a number of proceedings for health care workers accused of wrongdoing, and what she found sometimes shocked her—and even shocked some of the people responsible for making those disciplinary decisions. She shares some of those stories in the episode.

The Licensing Racket argues that licensing should be done away with for many professions. For those that remain, however, Allensworth believes much more must be done by government agencies rather than allowing professions to self-police themselves through volunteers and licensing boards
