Prediction markets can be directly subsidized with a market maker, allowing all traders who provide info to improve the price to expect to profit. Also, the more fools the more informed traders should be attracted to profit from them, so the mix is endogenous.

Professor Koleman Strumpf explains the prediction markets to the countryland people.

Ah, Kansas&#8230- Barbecues, pickup trucks, rednecks, country music, and&#8230- the local FOX News.

Despite that one blip on the radar [New Hampshire], Strumpf said futures are still the best way to predict the way things will go from here.

The Marketing Of The Reading Of The Public Prediction Markets = What Robin Hanson has deep trouble with, and what the prediction exchanges (e.g., InTrade-TradeSports, BetFair-TradeFair) havent fully computed yet

Robin Hanson on &#8220-silly&#8221- research topics:

[M]ost people think futarchy (government by [prediction] markets) is silly, even though most think it has a decent chance of performing well […].

Decision markets and decision-aid markets are 2 great concepts pushed by Robin Hanson, the world&#8217-s #1 researcher in the field of prediction markets. But they are just inventions, not innovations. What is important is to find out which population segment or which class of business executives find this stuff productive and helpful.

In that perspective, his presidential prediction markets at InTrade are good ideas, and the liquidity there (helped by an AMM) is decent enough. But they are just betting supports, right now. I haven&#8217-t seen any opinion leaders taking them as a trusted source of information, which is the damn goal. We will see whether that comes true in the future.

If Robin Hanson were really serious in finding a killer app for his concept of decision-aid markets, he would of course come up with conditional prediction markets in the realm of sports, which is the most popular topic in the real-money prediction markets. Alas, I often have the impression that the academics in the field of prediction markets have profound disdain for sports prediction markets.

Robin Hanson on seeking decision advice:

[…] We rarely seek out advice, and when we do it is usually on much smaller decisions. […] One reason we avoid getting advice is that it lowers our status relative to those who give advice. Of course this is also makes asking for advice a good way to flatter and supplicate. Not sure if this explains the puzzle though. But all this doesn&#8217-t seem to bode well for fielding decision markets on the biggest organizational decisions.

Allow me to digress from there. I think that the reading from the prediction markets is like an advice &#8212-in that you have to accept the market message as an authority. If you are an expert with direct access to primary sources of information, I don&#8217-t think you&#8217-d rely on the message from the public prediction markets (which are information aggregation laggards). The big mistake from Robin Hanson and the others has been to sell the public prediction markets as tools for the decision makers. That could happen, but marginally, I believe. Experts and decision makers will firstly want to rely on their primary sources of information and on their analysis.

I think that the population segment which is the more likely to appreciate the consumption of market-generated probabilities would be composed of people who want a chopper view of world events. Prediction market journalism should satisfy this dashboard need.

[Please note that the thoughts expressed above refer to the public prediction markets (as stated in the post title –think BetFair-TradeFair, InTrade-TradeSports, Betdaq, HubDub, NewsFutures, and Hollywood Stock Exchange) —not the enterprise prediction markets, which is a horse of another color.]

Robin Hanson on decision-aid markets:

I don&#8217-t recall ever turning down a chance to consult on prediction markets for a Fortune-500 company. If you know of an opportunity that I&#8217-m missing, do let me know.

Doc, are there more Fortune-500 executives and managers attending a conference on extra-terrestrials or a conference on finance? :-D

??? charity-driven prediction markets OR social issue prediction markets ???

BOTH.

But, contrary to what Lucy Berholtz thinks, the former will go further than the latter &#8212-in my view.

My thoughts about the Financial Times article on Bet2Give:

  1. I have said from day one that it&#8217-s a great idea.
  2. This is a &#8220-unique&#8221- concept&#8230- until InTrade-TradeSports, Betdaq and BetFair-TradeSports decide to create a charity wallet for their traders. Complex, sure, but that might come, one day.
  3. I have the highest esteem for Lucy Berholtz, generally, but I&#8217-m with Emile Servan-Schreiber on the idea that Bet2Give is not a simple marketing trick. All the money but a small percentage goes to the traders&#8217- selected foundations. If all US betting were organized that way, that would mean a huge windfall for US foundations.
  4. Tyler Cowen makes sense.
  5. As for LongBets, it&#8217-s a failed experiment in my judgment. Too many one-sided &#8220-predictions&#8221- for only a fistful of agreed &#8220-bets&#8221-.

Homer's brain

Unlike InTrade and NewsFutures, BetFair does not deliver any chart after that the prediction market has expired &#8212-leaving the blog post that linked to it totally blank (in a digital world where old content is King, and where Google sends traffic to old blog posts).

The BetFair marketing department is staffed by arrogant incompetents who are incapable of establishing a working relationship with prediction market bloggers like me.

There is nothing more important for our industry than the uprising of new blogs that would hot-link to the charts of prediction markets. The BetFair marketing team hasn&#8217-t computed that yet, in spite of all efforts made in their direction.

Of all the prediction market firms I talk with, BetFair is the most impermeable to the prediction market approach: their degree of arrogance is inversely proportional to their level of competency.

US Masters 2008 prediction markets

STRAIGHT FROM THE DOUBLESPEAK DEPARTMENT: NewsFutures CEO Emile Servan-Schreiber, well known to chase tirelessly the Infidels who dare calling prediction markets their damn polling system, is eager to sell the confusion to his clients and whomever would listen.

Emile&#8217-s made up a phrase that means nothing (except in his fertile imagination), &#8220-a proprietary prediction market variant&#8220- &#8212-sounds like a red herring to me.

Unlike Consensus Point, Inkling Markets and Xpree, NewsFutures is the only prediction market software vendor not to have adopted Robin Hanson&#8217-s MSR &#8212-a simplified trading technology now in use in most enterprise prediction markets.

Prediction Markets: Co-Creating An Organization&#8217-s Future – (PDF file) – by Inside Knowledge Magazine&#8217-s Victoria Axelrod and Jenny Ambrozek – 2008-05-10

David Perry of Consensus Point:

Yes, markets are early warning systems for many things, they give you a sense of what your people know and do not know.

Prediction markets are not necessary if everyone has perfect knowledge- markets are designed to tell people what they do know, to be quiet when they do not
know and are designed to get around take place over time, allowing for prices to fluctuate depending on traders’ confidence.

The longer the markets run, the more informed. They are like wine, they get better with time.

Emile Servan-Schreiber of NewsFutures is cited too.

Speculating on event derivative markets is not investing.

No GravatarUltra pertinent remark from the Club For Growth blogger:

[The New York Post video] is an informative video, but I want to quibble about two things. I view the term &#8220-investing&#8221- as the act of buying an asset with the hopes of it appreciating in value sometime in the future. Used correctly, you &#8220-invest&#8221- in a new home, a company on the stock exchange, or a baseball card collection.

However, you can&#8217-t &#8220-invest&#8221- in politics as the New York Post reporter said you could. The reason why you can&#8217-t is because contracts sold on prediction markets like InTrade.com are not assets– they are derivatives. Their value is based on the outcome of some event. Like futures contracts for frozen concentrated orange juice. [&#8230-]

I have been blogging about that for years, here, on Midas Oracle.

Video on InTrades political prediction markets

Via Yahoo! Research scientist David Pennock (pictured in the video, with, in the background, a whiteboard full of complex mathematical equations, which impressed the young New York Post journalist)&#8230- this New York Post video (embedded just below).



John Delaney&#8217-s statement that people (did he say &#8220-pundits&#8221- or &#8220-people&#8221-?&#8230-) were predicting a John Kerry victory in November of 2004 (while InTrade was predicting that George W. Bush would be re-elected) should be backed by supportive evidence. It&#8217-s difficult to quantify the chatter in newspapers, magazines, TVs, blogs, etc. Did someone do that for the 2004 presidential elections? I know that the polls were favoring Bush, slightly, but I don&#8217-t know whether the political buzz was quantified scientifically, really.
