Chris does alot of research into prediction markets, and has assembled an awesome collection of data and links at his meta-page. If you want more info on the subject, its a good place to start.
Chris and I have been having a debate about the efficacy of prediction markets; He was nice enough to make some informative comments about the Michael Jackson verdict, as well as sending us along another chart:
Announcement stating P. Purcell’s MWD resignation on/before 30 June 2005

Let me add that although neither of these two outcomes support Chris’ views, he did not hesitate to pass along the info. That’s the sign of a scholar, who’s interest lies in furthering the debate in order to determine the workings of market mechanism — as well as a gentleman.
I want to thank him for the pointer to the Purcell chart and for being such a good sport about this. (And how could it be anything but French Champagne?).
