Review of Jerold Zimmerman and Daniel Forrester's Relentless: The Forensics of Mobsters' Business Practices, Littleton, CO: Willowcroft, 2021, 261pp

Jerrold Zimmerman, an Emeritus Professor at the University of Rochester’s Simon School of Business, and Daniel Forrester, a Rochester MBA graduate turned top-level management consultant, are not the first to note the similarities between lawful and unlawful organizations, and their book, "Relentless: The Forensics of Mobsters’ Business Practices," is not the first study of organized crime using the principles of microeconomics. But it is perhaps the only book targeting primarily c-level executives, directors, and leaders of small and large for-profit and nonprofits to argue that lawful managers can learn from the way blood-stained villains unwittingly apply core economic principles to create enduring organizations that can thrive in constantly changing environments, despite substantial efforts (by rivals and law enforcement) directed at their demise.
