This story in the Wall Street Journal about the FTC's crackdown on a small non-profit association brings back memories of Goldfarb v. Virginia (i.e, in both cases, ethics codes contained provisions affecting price). The article is has a strong anti-FTC viewpoint, but for me the matter brought to mind Adam Smith's famous quote: "people of the same trade seldom meet together, even for merriment and diversion, but the conversation ends in a conspiracy against the public, or in some contrivance to raise prices."
Well into the story we learn that the FTC wanted the non-profit group to hire an antitrust compliance monitor who was a lawyer -- bringing to mind the recent articles Veronica Root has written about the new monitor-client relationship.
