Purcell & Prediction Markets

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.

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?).

    Best regards,

    Chris. F. Masse
