INTRADE are following the global financial crisis. Although this is not meant to be a free ad, 'Intrade, is The Prediction Market where you can buy and sell "shares" in financial, political, weather and other important subjects'.
Their latest email from John Delany on 28 January claims:
The Intrade World Crisis Index will tell us whether the Davos World Economic Forum Matters!
A higher post meeting index means our markets predict a more disastrous 2009 than before. A lower post-meeting index means our markets predict global leaders have reduced the probability that 2009 will be the disaster we previously thought.
We hope the global leaders convince our traders that 2009 will not be as bad as previously thought. We hope to see the index react to the keynote addresses.
