Tim Pawlenty won’-t go in Dayton, Ohio. So, it’-s Mitt Romney.
The play-money and real-money prediction markets were easily fooled with the Pawlenty rumors, yesterday.
That vindicates my message that the VP prediction markets feed on unreliable primary indicators.
I said from day one to be careful with the VP prediction markets.
I told you so.
UPDATE: It’-s probably Sarah Palin.
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 briefly fell into the 20s (rumors had it that Palin wasn’-t on a plane to Dayton- subsequently established that the rumor was not true), the contract turned sharply up to about 98 and stayed there until the selection was made official.
During that same time period, the “-Obama wins”- contract has slipped down a few percentages and the “-McCain wins”- contract is up a few percentages. Since at most VP selections are typically expected to affect final vote totals by 2 or 3 percent, the fact that the Obama and McCain contracts (which are winner-take-all, not vote-share contracts) have moved by 2 or 3 percent themselves suggests the markets think Palin is a fairly strong choice.
(But as I write this, the Obama contract is rallying back. Live blogging the prediction markets is hazardous stuff.)
UPDATE: As of Tuesday morning, both presidential markets have slid back to their pre-Palin-announcement levels, but active trading suggests continued disagreement about the information trickling into the market. Also interesting, activity has continued on the NEW-REP-VP-PALIN contract, with the price dipping below 95 (but back to 97 as I write). Since that contract expires at the convention – i.e. in a day or two – some folks are betting Palin will be off the ticket fast.
The New York Times has a recount on how Barack Obama reached his decision on Joe Biden. The final decision was probably made 10 days ago, while Barack Obama was vacationing in Hawaii.
[…] Mr. Obama’s decision had as much to do with Mr. Biden’s appeal among white working-class voters and compelling personal story, and his conclusion that the Delaware senator was “-a worker.”-
The important information in the NYT piece is that Barack Obama personally called governor Bill Richardson “-late last week”- to announce him that he was not considered anymore. That’-s around the time the Joe Biden rumor began to have more weight in the media circles —-see the InTrade chart below.
Bo Cowgill, back in May 2008 (when I started to act as a prophet of doom):
This is dumb. Cover them if something interesting happens. Maybe your theory will turn out to be wrong. Anyhow: Although the decision is made in secrecy, the Presidential nominees have a number incentives which we have plenty of information about. Specifically:
* They want someone who will balance their tickets in terms of geography, race and class.
* They want someone who will help with weak areas of their campaigns.
* They want someone who will be a good campaign surrogate — giving good speeches and attacking the opponents effectively.
* They want to avoid a VP who will de-motivate or offend the base.
* They want to avoid someone with a bunch of skeletons in the closet such as angry ex-wives, out-of-wedlock kids, etc.
* Etc etc.
Anyhow, I don’t see any reason to ignore these markets in case something interesting happens. I read Midas Oracle so that I don’t *have* to read a whole bunch of other websites!
Bo Cowgill was on the right track, now that I think of it —-in a society where everything leaks out.
On the opposite of the spectrum, Tom Snee was too much extreme in his view:
According to Tom Snee of the Iowa Electronic Market, at Iowa University, futures markets need more hard information than they get in the veepstakes, to reliably predict a result.
Markets are very good at predicting elections, he says – but not choices being made inside Barack Obama’-s or John McCain’-s head.
Justin Wolfers was more measured.
So, Bo Cowgill and Justin Wolfers are the winners, on that one.
I was partially wrong. I am a bit too extreme, sometimes. (Did someone else notice that? 
) I need to learn more about…- granularity.

PS: On the Republican side, now…-
Who will be the Republican Vice Presidential Nominee?
As I explained in early June 2008, the VP speculations that appear in the Press should never be taken seriously. Most of them (and you don’-t know which ones) are a big orchestration of pure lies aimed at creating publicity, or wicked lies in the form of trial balloons. The aims of the political campaigns are to:
]All that means that there are no good primary indicators for the prediction markets on the Democratic and Republican VP-candidate selections.
I want to offer 6 remarks:
That said, I wish the very best of luck to our good friends Caveat Bettor (who is betting on Tim Kaine) and Nigel Eccles (who is predicting Joe Biden).
UPDATE: My (informal) Democratic VP-candidate bet is on Kathleen Sebelius. Hint, hint.
UPDATE: Gawker says that Joe Biden would be a horrible choice. I agree. Plus, he has denied to be the pick. He could have lied to reporters, though.
UPDATE: New York Times publishes portraits of all VP candidates.
DEVELOPING…-

The McLaughlin Group of mid-June (yes, I know, that’-s last month):
MS. BERNARD: Well, here’-s what I think. I think the dirty little secret is Barack Obama probably already knows who he’-s going to select to be his vice presidential running mate. You put out the search committee, probably because Hillary Clinton was all over his back last week –-
DR. MCLAUGHLIN: So this is a smokescreen. This is a smokescreen.
MS. BERNARD: I don’-t know if it’-s a smokescreen, but I think he has a good idea who his vice presidential running mate is going to be. And the search committee is much ado about nothing.

I told you so.
No good advanced, primary indicators.
Don’-t trade on VP prediction markets.

#1. Don’-t trade on the VP predictions markets.
I have stong reservations about those VP prediction markets. Only 2 men in the world know what is going to happen: Barack Obama, and John McCain.
You can’-t divine their final thoughts.
Politicians often lie about their intentions —-they also change mind, frequently.
The decision to name one VP nominee could be made in secret —-without any early warnings.
Surprise is a card that Barack Obama and John McCain could play. Don’-t bet against their final will.
–
#2. Don’-t believe in “-vice presidential selection committees”-.
Last time, in 2000, a man named Dick Cheney was appointed to head George W. Bush’-s vice presidential selection committee.
He was supposed to scout around to find and assess good candidates.
Surprise, surprise, that fake committee ended up putting Dick Cheney on the Republican ticket —-and the rest is history (Iraq war, etc.).
–
#3. Don’-t bet on Hillary Clinton as VP.
She does not have the slightest chance.
It’-s highly unlikely that Barack Obama selects her on the Democratic ticket.
Hillary Clinton as VP nominee (and as VP) would present many quasi insurmountable problems.
–
#4. Don’-t listen to betting bloggers who tell you that Hillary Clinton has a chance to be on the Democratic ticket.
They are clueless.
Don’-t read clueless people. They are a waste of time.
–
#5. Select well your primary, advanced indicators.
–
#6. Choose your bets (and trades) carefully.
Just because an event derivative is cheap doesn’-t mean that it’-s a good bet.
Don’-t pluck down money on a bet unless you’-ve seriously researched the topic by yourself —-and possesses some expertise or experience in that field.

Prediction markets produce dynamic, objective probabilistic predictions on the outcomes of future events by aggregating disparate pieces of information that traders bring when they agree on prices. Prediction markets are meta forecasting tools that feed on the advanced indicators (i.e., the primary sources of information). Garbage in, garbage out…- Intelligence in, intelligence out…-
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 can be interpreted as the objective probability of the future outcome (i.e., its most statistically accurate forecast). A 60% probability means that, in a series of events each with a 60% probability, then 6 times out of 10, the favored outcome will occur- and 4 times out of 10, the unfavored outcome will occur.
Each prediction exchange organizes its own set of real-money and/or play-money markets, using either a CDA or a MSR mechanism.

Don’-t you love the Web? Within 15 minutes after my posting my absolute and definitive refusal to publish any bits about the VP prediction markets, I received a long rebuttal by Google’-s Bo Cowgill —-whose great prediction market paper is still for you to download (PDF file), by the way.
Okay, Okay, Okay.
