George Tziralis should have refined a bit the statement he made in the first video below &#8212-statement which I have slightly modified in the title above. We need inputs from the primary, advanced indicators, the experts, and the prediction markets. We need all of that. The prediction markets will never eliminate either the polls or the experts. The prediction markets come as a supplement in the mix.




Ask Markets

Lets face it. The political world doesnt give the first fig about the prediction markets, InTrade, BetFair, Betdaq, NewsFutures, HubDub, Robin Hanson, Justin Wolfers, and the rest of our little clique.

No GravatarSome of our luminaries have had their vapors and have boldly stated that the public [*] prediction markets would soon take over the free world and become the forecasting tool of choice for decision makers. Since our movement has started, in 2003, that has not happened &#8212-and will never happen (let alone in the year 2020). We were duped by those cocky misleaders. In the coming weeks, I&#8217-m going to try to launch a big intra-industry initiative to find the right usage for the public prediction markets. Stay tuned&#8230- and I hope I&#8217-ll get you on board with me.

[*] as opposed to the enterprise prediction markets, which is not the topic of my bombastic rant above, which is a horse of another color, and which would deserve a completely different analysis.

Polls Vs. Prediction Markets

Asia Times:

[&#8230-] Outperforming Taiwan&#8217-s polls shouldn&#8217-t be hard. They&#8217-re notoriously bad as a forecast of election outcomes. In late 2006, for example, many media polls underrated the pro-independence party&#8217-s support – a recurring problem. Taiwan&#8217-s prediction markets did a much better job of estimating vote shares (the island&#8217-s two markets both called the Kaohsiung mayoral election wrong, but that contest was a statistical dead heat). &#8220-Most opinion polls usually have 20 to 30% &#8216-no answer&#8217-,&#8221- said Lin Jih-wen, director of the Center for Prediction Markets. &#8220-We don&#8217-t have missing data or a sampling bias, that&#8217-s our strength.&#8221-

The market has now picked the strong likelihood of victory by the China-friendly candidate Ma Ying-jeou. Time will tell if it&#8217-s got the right guy. But even if it doesn&#8217-t, the markets&#8217- enthusiastic reception shows how Asia – like the US and Europe – has embraced such markets as a powerful fortune-telling tool.

A &#8220-powerful fortune-telling tool&#8221-? Jesus. :-D

&#8220-Outperforming&#8221- the Taiwanese advanced indicators which they are feeding on? Humm&#8230- :-D

[Mike Giberson will write a comment, below, reminding me of Prof Koleman Strumpf&#8217-s work (PDF file) showing that the historical prediction markets were accurate enough, even though the scientific polls were not invented yet. Yes, I know of that, Mike, but I still don&#8217-t get whether it&#8217-s a puzzle or a mystery. :-D &#8230- Do you?]

When Markets Beat The Polls – Scientific American Magazine

No Gravatar

Via Mat Fogarty of Xpree (an innovative firm providing software for enterprise prediction markets), the Scientific American magazine on prediction markets &#8211-&#8221-When Markets Beat the Polls&#8221-.

Ask me by e-mail to get a copy of the PDF file.

Abstract:

When Markets Beat the Polls– March 2008- Scientific American Magazine- by Gary Stix- 8 Page(s)

In late March 1988 three economists from the University of Iowa were nursing beers at a local hangout in Iowa City, when conversation turned to the news of the day. Jesse Jackson had captured 55 percent of the votes in the Michigan Democratic caucuses, an outcome that the polls had failed to intimate. The ensuing grumbling about the unreliability of polls sparked the germ of an idea. At the time, experimental economics&#8211-in which economic theory is tested by observing the behavior of groups, usually in a classroom setting&#8211-had just come into vogue, which prompted the three drinking partners to deliberate about whether a market might do better than the polls.

A market in political candidates would serve as a novel way to test an economic theory asserting that all information about a security is reflected in its price. For a stock or other financial security, the price summarizes, among other things, what traders know about the factors influencing whether a company will achieve its profit goals in the coming quarter or whether sales may plummet. Instead of recruiting students to imitate buyers or sellers of goods and services, as in other economics experiments, participants in this election market would trade contracts that would provide payoffs depending on what percentage of the vote George H. W. Bush, Michael Dukakis or other candidates received.

Robin Hanson had more.

The GOP SC and Dem NV Showdown: Intrade v. Zogby

No Gravatar

If McCain wins SC, the GOP contest will be called for Intrade. If Thompson or Romney wins, that contest will be called for Zogby. If any other GOP candidate wins, the contest will end in a draw.

If Obama wins NV, the Dem context will be called for Intrade. If Edwards wins, that contest will be called for Zogby. If H.Clinton or another candidate wins, the contest will end in a draw.

Zogby does not have recent information posted about the GOP in NV nor the Dems in SC, so a meaningful contest with Intrade cannot be had. While it&#8217-s not a forfeiture by Zogby, at least it&#8217-s a tiebreaker for Intrade.

The Future of the Prediction Markets

No GravatarEven a prediction market fanboy feeds on the polls &#8212-first and foremost. Steve Dubner, the journalist and co-author of Freakonomics, is, along with his two blog colleagues (Steve Levitt and Justin Wolfers), a strong supporter of the prediction markets. They all have blogged enthusiastically on prediction markets, since the inception of their blog. Steve Levitt calls the InTrade-TradeSports people in Ireland his &#8220-friends&#8220-. Wow. The Freakonomics blog even has a &#8220-Prediction Markets&#8221- blogroll (i.e., a list of external weblinks to the best resources on prediction markets) &#8212-where, of course :-D , Midas Oracle is the cornerstone. :-D To sum it all up, Steve Dubner and his colleagues are true believers in the predictive power of the prediction markets. Good.

Until you analyze this Steve Dubner&#8217-s Freudian lapsus:

[&#8230-] (Fascinating aside: according to a recent Times poll cited in the article linked above, the Florida G.O.P. race is as of now a virtual deadlock between four candidates: Huckabee, Giuliani, McCain, and Romney. This will almost certainly shift as a result of interceding activity, but still, what a spectacle!)

Which forecasting tool does Steve Dubner use to get a sense of the political race du jour? Not the prediction markets&#8230- but the polls.

That speaks volume on the nature of the prediction markets, as forecasting tools.

  1. The polls and the surveys are the primary purveyors of crucial political information, which the political analysts (and&#8230- Steve Dubner :-D ) use to write their reports.
  2. The political prediction markets feed on polls, aggregate them (and other disparate pieces of information), and delivers &#8220-the consensus opinion in a much finer and dynamic way than all the amorphous media buzz&#8220-. They are secondary forecasting tools. They are taken seriously only by the free-market believers (like us) &#8230- but, as the Steve Dubner&#8217-s quote shows, even the prediction market true believers check the polls first.

I think that:

  1. Because of its nature, the prediction market prism, which quantifies the impact of the news, will never be the dominant forecasting tool.
  2. Prediction market journalism will remain on the fringe. It should be developed to serve a targeted audience &#8212-the free-market believers, the busy people, and the event derivative traders.
  3. Conditional prediction markets (a.k.a. decision-aid markets) will never be taken seriously by the decision makers and the public. Robin Hanson&#8217-s tool is very smart, though. Applications should be found within the community of free-market believers, rather.
  4. Enterprise prediction markets (a la Google, Inkling Markets, Consensus Point, etc.) are very interesting because they reflect inside information that can&#8217-t be conveyed by the corporations&#8217- internal media.
  5. The prediction market approach (embodied by InTrade) will always be weaker than the betting exchange approach (embodied by BetFair). I still believe, though, that each prediction exchange should employ both &#8212-which is not the case, right now.

&#8212-

ADDENDUM: In fairnesses to Steve Dubner, it should be noted that, in the same post, he put up a blunt challenge to polling methodology:

[&#8230-] As for the discrepancy between the two polling questions, take note: that’s the difference between a fill-in-the-blank polling question (i.e., “Which is the most important problem …”) versus a leading polling question (”Do you view crime as a ‘very serious problem’?”). The next time you read a poll and think it may be hinky, ask yourself what question the pollsters actually asked. [&#8230-]

We have witnessed a backlash against the prediction markets just after the Hew Hampshire fiasco. Some bloggers and journalists picked on the prediction markets (InTrade, that is), even though both the polls and the pundits were awfully wrong too. [*] Here are the persons who participated in the pro-PM side of the debate:- Robin Hanson at Overcoming Bias (the best pro-PM piece so far, although his phrasing is a bit too long and a bit too complicated for the average citizen)-

– Justin Wolfers in the Wall Street Journal (who did not convince Felix Salmon, who in tun did not convince me :-D )-

– Chris Masse at Midas Oracle (see Tim Harford&#8217-s new post to discover how irrational Chris Masse really is :-D )-

VENERABLE LAW SCHOLAR CASS SUNSTEIN REBUTS PAUL KRUGMAN AND COMES OUT TO DEFEND THE PREDICTION MARKETS.

No GravatarCass Sunstein:

[&#8230-] Some people are now doubting not only the prediction markets but also the polls, saying that no one knows anything, and that anything is as likely as anything else. Don&#8217-t believe it. To be sure, we are continuing to obtain information about how prediction markets perform and when they do well and poorly. Perhaps they will turn out to be less reliable than they seem &#8212- and in all likelihood, we will obtain a better understanding of when they work. And of course no one has a crystal ball. But the polls are generally pretty good &#8212- and if you want to have a sense of the probabilities, you&#8217-d probably do best to consult Intrade.
