Accurate predictions are essential in many areas such as corporate decision making, weather forecasting and technology forecasting. Prediction markets help to aggregate information and gain a better understanding of the future by leveraging the wisdom of the crowds. Trading prices in prediction markets thus reflect the traders' aggregated expectations on the outcome of uncertain future events and can be used to predict the likelihood of these events. This book demonstrates that markets are accurate predictors. Results from several empirical studies reported in this work show the importance of designing such markets properly in order to derive valuable predictions. Therefore, the findings are valuable for designing future prediction markets.

This is the catalog of a joint exhibition by the two New York artists Andrea Geyer and Sharon Hayes. It also features dialogues with a number of central artists in the field of feminist enquiry.

Andrea Geyer was the prime discovery at documenta XII. In quietly revealing works made up of both image and text, photographs are combined with historical data, news, and fictional travel reports.

Sharon Hayes explores social realities by searching for historical parallels. She always chooses themes that have inscribed themselves in US history, with traumatic consequences. Hayes is included in the Whitney Biennial 2010.
