IEM Data Used To Analyze Upcoming Election

An opinion piece about the presidential race draws heavily from data provided by the UNIVERSITY OF IOWA HENRY B. TIPPIE COLLEGE OF BUSINESS-RUN IOWA ELECTRONIC MARKETS (IEM), including a graphic comparing the 2004 presidential vote share market vs. the S&P 500. The writer states, "As a measure of Sen. John Kerry's likelihood of election, data is used from the trading of real money future contracts based on election outcomes run by the Iowa Electronic Market. Academic research has shown that this market has been a very accurate predictor of elections -- better than large-scale polling services."
