Best Buy Taps 'Prediction Market'†

Imaginary Stocks Let Workers Forecast Whether Retailer's Plans Will Meet Goals

Wall Street Journal, September 16, 2008 — When executives at electronics retailer Best Buy Co. want to know if a new product or idea is likely to succeed, they can seek the opinion of rank-and-file employees by turning to the company's "prediction market."

The market, called TagTrade, allows Best Buy's workers to trade imaginary stocks based on answers to managers' questions. The market's judgment has often proved to be more accurate than the company's official forecasts.
