Prediction Markets = Collective Forecasting = Collective Intelligence That Predicts

Can prediction markets help improve economic forecasts?

Contrary to the suggestion of Hendry and Reade, I don’t think “model averaging” is a useful explanation of what prediction markets do.

What’s the big deal about the fluff on prediction markets in The Economist?

Chris Masse has posted several times about the recent piece on prediction markets in The Economist. Among his recent grand pronoucements:
“If you are a prediction market consultant, and have nothing to say about the negative piece from The Economist, then you don’t matter anymore.”
Really?
What is it that The Economist said that prediction market consultants should [...]

Where is the post-election academic conference on prediction market performance?

Giberson asks, “Where is the 2008 post-election academic conference on prediction market performance going to be?”

Quit mulling over the VP-choice prediction markets, today’s real story is in the election winner markets.

I would suggest that the VP selections and the performance of the VP-choice markets at InTrade and elsewhere lend some validity to Chris Masse’s views on such markets. But enough about the VP markets, already. The interesting developments are in the election-winner markets.

Since just after 2 PM Irish time, when the NEW.REP.VP.PALIN contract [...]

What public interests are served by event contracts?

Comments continue to trickle in at the U.S. CFTC, in response to the agencies request for comments on its “concept paper on event contracts.” You can find the comments posted so far, all seven of them, on the CFTC’s website. Likely many more comments will be filed around the July 7 deadline, and [...]

Is the promise of prediction markets in the United States best explored in limited, small stakes markets under a CFTC safe harbor declaration?

I haven’t turned up the latest edition of Science magazine mentioned yesterday by Chris F. Masse, but a version of the Science article “The Promise of Prediction Markets“, is available from the AEI Center for Regulatory and Market Studies (find link to article on this page).
The first thing of note is that the extensive list [...]

The CFTC takes a necessary step toward sorting out its role with respect to prediction markets.

As noted here in multiple posts over the past few days, the U.S. Commodity Futures Trading Commission is thinking about prediction markets. Last week it released a “Concept Release on the Appropriate Regulatory Treatment of Event Contracts” and invited public comments on several questions as it attempts to sort out its proper role, if any, [...]

Who would you back, the market consensus or a book-writing pundit?

Tyler Cowen picks the market consensus over book-writing pundits:
Either the current market estimate of inflation is the best estimate available, or you know that it is wrong and you will be a very rich man. I find the former scenario more plausible.
Cowen is commenting on the Kevin Phillips book, Bad Money, recently out.
Of course book [...]

Super Tuesday = Free money, if you are smarter than the crowd

At Overcoming Bias, Eliezer Yudkowsky invites pundits, partisans, and anyone else with a nascent opinion about the limits of prediction markets to, in effect, put up or shut up. (Though he puts it in somewhat nicer words). Here is a selection, but read the whole thing:
If you think that Hillary is going to [...]

Better Pricing for Tournament Prediction Markets

Last year while working out a few thoughts on arbitrage opportunities in basketball tournament prediction markets at Inkling, it occurred to me that the Inkling pricing mechanism was just a little bit off for such applications. The question is whether something better can be done. An answer comes from the folks at Yahoo Research: yes.
Inkling’s [...]
