Media Futures Market Achieves "Astonishing Accuracy"

The passage below is quoted from a WSJ summary of an article that appeared in the July 9-16, 2007 issue of The New Yorker:

(p. B8) The most successful media prediction market is the Hollywood Stock Exchange. According to a study by Harvard Business School professor Anita Elberse, the markets' forecasts of box-office performance are off by 16% on average. That's astonishing accuracy for an industry which, despite all kinds of attempts to predict what will work, assumes that the vast majority of its product will fail at the box office.
