THE LATEST NEWS

-

- The media are running stories about future “record turnout” among young voters. I am a bit prudent, since the media ran this kind of stories in 2004, saying that the voting youth would favor John Kerry —we know how it all ended up. Let’s wait and see.

- The stock markets are slightly up this Thursday morning. However, once the stock investors have read the New York Times investigation of how A.I.G. is rapidly burning all of the $123 bilion in “emergency lending” they received from the Treasury, I bet that the Dow Jones will end up South.

- Karl Rove tells the Wall Street Journal readers that voters should not believe in polls, since “they were wrong in 2000 and 2004″. Hummm… His Op-Ed is not convincing, because the 2000 election was a very close election and the 2004 election was a somewhat close election. It seems different today. Some pundits are predicting a “landslide” for Barack Obama.

- The man running the popular site “Electoral-Vote.com” website deflates the big egos of the crétins who assume that InTrade is a magical tool. Very likely, the [InTrade] bettors are prime consumers of polling data.” He is right. If you haven’t done already, please read the analysis I have done about the real utility of the InTrade prediction markets on the US elections.

- The online magazine Slate has run a poll inside its news desk —asking employees for whom they are going to vote. All of the Slate journalists will vote for Barack Obama —except one who will vote for John McCain, and another one (Jack Shaffer) who will vote for the Libertarian Party. So now you know we have a liberal Press.

- Speaking of the Press, I spotted 2 negative stories about John McCain’s character. One by David Broder in the Washington Post. Another one by Andrew Sullivan.

- The most surprising thing I have read this morning in the Press is a short affidavit from Francis Fukuyama telling his fellow conservative citizens that he is going to vote for Barack Obama, on the ground that both George W. Bush and John McCain are not Reaganian enough. But what about voting for a Socialist, then?

- If you read my first story on the “Reverse Bradley Effect”, please read the follow-up post that takes a second look on whether race will play a role in the November 4 elections.

- Right-click on this link, and open it in another browser tab —it’s a short, rolling, historical panorama of how the US states voted since the inception of America.

- The HubDub traders are predicting that more than 50 million people have watched the Barack Obama informercial.

- Here’s the video of the (Socialist) informercial run Thursday nite by the Barack Obama campaign:

#1. Explainer On Prediction Markets

-

A prediction market is a market for a contract that yields payments based on the outcome of a partially uncertain future event, such as an election. A contract pays $100 only if candidate X wins the election, and $0 otherwise. When the market price of an X contract is $60, the prediction market believes that candidate X has a 60% chance of winning the election. The price of this event derivative represents the imputed perceived likelihood of the partially uncertain event (i.e., its aggregated expected probability). A 60% probability means that, in a series of events each with a 60% probability, the favored outcome is expected to occur 60 times out of 100, and the unfavored outcome is expected to occur 40 times out of 100.

Each prediction exchange organizes its own set of real-money and/or play-money markets, using either a CDA or a MSR mechanism —with or without an automated market maker.

Prediction markets enable us to attain collective intelligence. Prediction markets produce dynamic, objective probabilistic predictions on the outcomes of future events by aggregating disparate pieces of information that the traders bring when they agree on prices. The event derivative traders are informed by the primary indicators (i.e., the primary sources of information), like the polls, for instance. These informed speculators then execute their transactions based on their anticipations about the future —anticipations that will be either confirmed or infirmed.

The value of a set of prediction markets consists in the added accuracy that these prediction markets provide relative to the other forecasting mechanisms, times the value of accuracy in improved decisions, minus the cost of maintaining these prediction markets, relative to the cost of the other forecasting mechanisms. According to Robin Hanson, a highly accurate prediction market has little value if some other forecasting mechanism(s) can provide similar accuracy at a lower cost, or if very few substantial decisions are influenced by accurate forecasts on its topic.
