John Delaney – InTrade – US Politics – Fox News – YouTube – 2007-02-27
Very good explainer.
John Delaney mentions Justin Wolfers and Robin Hanson. It could be that the papers he refers about were written by the Iowa Electronic Markets scholars, instead. (I could be damn wrong, possibly.)
As for the metaphor with the NYSE, I disagree [...]

Our good friend Barry Ritholtz is quick to draw funest conclusions:
While the Political futures got the House right, it appears they were wildly wrong about the Senate. That would be quite a blow to these thinly traded, tiny markets. And of all the things they tend to get right, elections are their forte. If [...]

OPEN LETTER TO THE COMMENTERS OF THE MARGINAL REVOLUTION BLOG
