The application of prediction markets to business

Abstract

According to financial theory, open markets efficiently and effectively aggregate all available information about future events into their prices. Recent empirical evidence has shown that speculative markets, from gambling to web-games, are better at predicting the future than more commonly used statistical or survey-based forecasting methods. As a result, a number of companies have conducted experiments to evaluate the use of prediction markets as an alternative forecasting methodology. This paper offers a comprehensive framework for determining when and how prediction markets should be employed in a business context.
