Purcell & Prediction Markets

Monday, June 13, 2005 | 09:24 PM

You may recall that I previously mentioned Chris Masse's informative Prediction Markets Vortal.

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:

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?).

Hello Barry Ritholtz,

When it comes to assessing whether some official will quit under pressure, it is the second time that prediction markets fail us. On the link that I provide above, you will find the graph of the George Tenet futures market ---a miss.

We, guys in the field, should reflect on that. I will soon.

Best regards,
