Michael Guttentag, the John T. Gurash Fellow in Corporate Law and Business, focuses on the intersection of law and markets, and specifically on how law can be used as a tool to share resources fairly and efficiently. A former corporate insider, much of his research considers how securities markets should be regulated and why insider trading should be prohibited. He has used a variety of methods to carry out this research, including conducting experiments and developing mathematical models, has published numerous articles, and recently received a research grant from the Progress and Poverty Institute.
Guttentag’s most recent work calls for legislation to establish a comprehensive federal insider trading ban in the U.S. In a chapter published in 2025 in the “Research Handbook on Insider Trading,” Guttentag laid out the economic case for insider trading law reform. He also continues to explore ways legal rules can be used to simultaneously address inequality and enhance productivity, publishing in the Boston University Law Review and in the evolutionary psychology peer-reviewed publication, Evolution and Human Behavior.
In 2024, Guttentag was featured on the Business Scholarship Podcast to discuss “What Insider Trading is Worth and Why It’s Valuable.” He has given presentations on various aspects of securities regulation at the National Business Law Scholars Conference, the Association of American Law Schools Conference, the Southeastern Association of Law Schools, and the American Law and Economics Association.
Prior to his career in academia, Guttentag worked as an executive in the public and private sectors, where he held senior management positions in the Internet, entertainment, and financial services industries. From 2005 to 2008, he was a member of the faculty of the Boyd School of Law, UNLV, and has visited at the Emory University School of Law, UCLA School of Law, and USC Gould School of Law. He joined the Loyola Law School faculty in 2008. Guttentag is a member of the American Law and Economics Association, the Society for Empirical Legal Studies, the Bar of the State of California, and a past Chair of the Association of American Law Schools Section on Securities Regulation.
