New Prediction Market: Dominique Strauss-Kahn
Tuesday, May 17, 2011

On May 16th 2011 Dominique Strauss-Kahn appeared in New York City Criminal Court and was charged with two counts of a criminal sexual act in the first degree , first-degree attempted rape, first-degree sexual abuse, second-degree unlawful imprisonment, forcible touching, and third-degree sexual abuse. These seven charges are detailed in the criminal court complaint found HERE.

Intrade has opened a market for Dominique Strauss-Kahn to be found guilty of, or plead guilty to, at least one of the charges laid against him. This market can be found under Legal &gt- D. Strauss Kahn.

InTrades prediction markets on secretive events are just an Irish scam. – [ANALYSIS]

Paul Hewitt:

How do we know the Intrade price was not accurate? Well, the raid wasn’t just executed on a whim. It had been planned for quite some time. Therefore, the true likelihood must have been much higher than the four or five percent chance the market was telling us.

Many people knew of the plans, albeit they were very high ranking, sworn-to-secrecy types. Since the market did not reflect the potential success of the planned raid, either the market was inefficient or the market, in an aggregate sense, did not possess enough information to make a reasonably informed prediction. In this case, I have to believe the market participants (every last one of them) knew next to nothing about the outcome being predicted.

The Intrade market prediction was nothing more than an aggregation of guesses. This is very different from an accurate prediction (based on calibration) that turns out to be wrong.

Markets such as these have no use, whatsoever, in decision-making. The useful information was that gathered by the SEALs and other secret services, and that was the information provided to the real decision-maker, The President. I would argue that these types of markets have no place as betting markets either. There is no way to test the calibration, so we don’t know whether they are “fair” markets (unlike the accurate calibration of horse races and casino games).

In other words, stop wasting our time operating and analyzing these markets. They are never going to be useful.

InTrade on the elimination of Osama Bin Laden – [ANALYSIS]

Mike Giberson:

How do we know, now, that Intrade&#8217-s market price was not an accurate estimate of the probability bin Laden was killed or captured by September 2011? Is an prior estimate of 50 percent likelihood that a tossed coin will come up heads wrong if the coin comes up as &#8220-100 percent&#8221- heads (and not half-heads and half-tails)?

I&#8217-m not buying Chris&#8217-s implied definition of success and failure.

However, one might ask Robin Hanson about what the Intrade market&#8217-s performance implies about the usefulness of his Policy Analysis Market idea.

Note that I was contrasting the InTrade-Bin-Laden failure with the high expectations set by Robin Hanson, Justin Wolfers and James Surowiecki.

Also, other than statisticians, most people don&#8217-t have a probabilistic approach of InTrade&#8217-s predictions. That&#8217-s the big misunderstanding, which is one part of the big fail of the prediction markets.

InTrade was not able to predict the elimination of Osama Bin Laden. – [PREDICTION POST-MORTEM]

I already blogged about the big fail of the prediction markets. Here&#8217-s more from the NYT, Eddy Elfenbein, and Barry Ritholtz.

Cold Fusion Prediction Markets – [HISTORY]

In April 1989, Robin Hanson created this prediction market:

By 1/1/91 a &lt-1 liter device will have generated over 1 watt of power output more than input from room-T fusion, including amortized power to create/separate components.

I suppose that InTrade will be willing to float E-cat contracts. We&#8217-ll see.

Justin Wolfers pumped up the shitty, play-money prediction exchange run by InTrade/WSJ.

Shit here.

The fake-money exchange is pitiful, and to have a professor pumps up that shit is pitiful too.

UPDTE: That was the 2008 election. Fortunately, this crappy exchange is dead. Here&#8217-s Freakonomics on the 2010 election.

David Pennock wants you to believe that InTrade needs Robin Hansons automated market maker.

&#8220-Our market maker automatically adjusts its level of liquidity depending on trading volume. Prices start off very responsive and, as volume increases, liquidity grows, obviating the need to somehow guess the &#8216-right&#8217- level before trading even starts.&#8221-
