The George Mason Journal of Law, Economics, and Policy has a splendid symposium coming up on January 27, "Perspectives on Insider Trading." The symposium commemorates the 40th Anniversary of the publication of Henry Manne's book, "Insider Trading and the Stock Market." In addition to Henry, participants include Jonathan Macey, Fred McChesney, David Haddock, and others. The program will be at George Mason Law School and the papers will be published in the journal.
The full program and registration information is available here.
Also, for those who can't attend, the talks will be available downloading later as a podcast. Earlier JLEP programs are also available as podcasts. I'm the faculty advisor to the journal and I've been quite impressed at the number of podcasts downloads of prior programs there have been.
