There’s a new information quasi-market called SciCast based on “crowd sourcing” methods and reputation effects, not on prices–i.e. participants who make the most accurate predictions move up a symbolic scoreboard but are not paid with real money. You could argue that one well-designed quasi-market is better than a thousand partisan pundits, but without real stakes or wagers, are fake prediction markets doomed to fail in the long run?

Another fake prediction market?
