A few academic papers that may be of interest to readers of The Signal:

Predicting consumer behavior with Web search (with Sharad Goel, Jake Hofman, Sebastien Lahaie, and Duncan Watts). In Proceedings of the National Academy of Sciences, 2010. We show that what consumers are searching for online can predict their collective future behavior days or even weeks in advance. We use search query volume to forecast the opening weekend box-office revenue for feature films, first-month sales of video games, and the rank of songs on the Billboard Hot 100 chart, finding in all cases that search counts are predictive of future outcomes.

Designing Markets for Prediction (with Yiling Chen). In AI Magazine, 2010. We survey the literature on prediction mechanisms, including prediction markets and peer prediction systems. We pay particular attention to the design process, highlighting the objectives and properties that are important in the design of good prediction mechanisms.

Prediction Without Markets (with Sharad Goel, Daniel Reeves, and Duncan Watts). In ACM Conference on Electronic Commerce, 2010. We compare the performance of prediction markets to polls and statistical models, examining thousands of sporting and movie events. All these domains exhibit remarkably steep diminishing returns to information, with nearly all the predictive power captured by only two or three parameters.
