Anyone interested in the psychology of negotiation is likely to be well acquainted with the scholarship of Professor Russell Korobkin, who is Vice Dean for Academic and Institutional Affairs and Richard C. Maxwell Professor of Law at UCLA Law School (for the breadth of his scholarship, see here). Professor Korobkin recently gave the 2019 Chris Beecroft Jr. Lecture at the UNLV William S. Boyd School of Law, entitled “Behavioral Ethics and Legal Negotiation.” The lecture provides a wonderful overview of the field of behavioral ethics and how it relates to types of ethical issues that arise during legal negotiations (as an added benefit, the lecture is introduced by Professor Jean Sternlight, Director of the Saltman Center for Conflict Resolution at UNLV Law School, whose work essentially co-founded the field of Behavioral Legal Ethics).
