Prediction markets

The aim of this project was to develop and evaluate a prediction market tool that higher education institutions can use to rank outputs for potential REF submissions as part of their internal REF (Research Excellence Framework) planning. A prediction market is a bit like the stock market, except instead of investing in companies, participants invest in the outcomes of future events (in this case, ratings of research outputs). This presentation will give some background to the project and details of the prediction markets that have been tested with Units of Assessment at the University of Bristol. It will include a demo of the tool used and the lessons learned from the first round of markets.
