Justin Fox at HBR has an interesting analysis of the recent rash of insider trading cases, in the course of which he comments that:
... the insider trading prohibition has been elaborated through Supreme Court decisions and SEC orders in the U.S., and has spread to many other countries as well. It has also been the source of unending discussion and controversy among legal scholars. Just in the past few months, the Columbia Business Law Review has come out with an entire issue devoted to the topic (based on a symposium held at Columbia last fall), and Edward Elgar has published a 512-page Research Handbook on Insider Trading edited by UCLA Law Professor (and prolific blogger) Stephen Bainbridge.
I will not claim to have read all or even most of the contributions to these volumes (law professors write long), but just dipping into them is an educational if bewildering experience. (The Langevoort article cited above is from the Columbia Business Law Review; my brief history of insider trading law is partly cribbed from Bainbridge’s introduction to the Handbook.)
