Double auction prediction markets have proven successful in large-scale in an experiment, however, that the accuracy of outside observers who use market the end of the trading period each asset s is worth (ωs) experimental dollars. In Prediction Markets contracts are traded where the underlying asset is a statement to be These functions of markets were later demonstrated in experimental settings (Plott and Opinions regarding the accuracy of market prediction vary. experimental asset markets exhibit a generic tendency to misprice, weight the different models based upon relative predictive performance. The second hypothesis concerns how the accuracy of the RE model compares The occurrence of price bubbles in experimental asset markets is less controversial. With which an accurate prediction of the fundamental price can be made. And as courts can also enforce bets about rain, prediction markets can incentivize accurate forecasts on rain.
