A few months ago I had a post describing information markets, a system
of buying and selling securities that pay off if a given future event
happens. Based on the price of a security, one can get an estimate of
the probability that that event will occur. Studies have shown that
information markets are better predictors than polls or experts.
Information markets have taken a blow in the past few days. The US
Department of Defense has cancelled a program that would have set up
limited futures markets on securities based on terroristic
activities. They bowed to pressure from senators who consider it
morally wrong to bet on events on future terrorist attacks. I
understand their concerns but computer scientists and economists have
produced what could have been a powerful tool in controlling
terrorism and it is quite a shame to see it discarded so easily.
David Pennock sent me some links on a more positive point of view from
CNN,
Fortune and
Wired and a fun
CNN piece
on the Tradesports Poindexter future.
