Dan at Predictably Irrational further discusses the results of his FREE! experiment.  Basically, the simple fact that something is made available free creates a preference for that good even when the relative difference in price between that good and a presumably better one stays constant.  However Dan recounts the results of some different variations on [...]

More on a Data-driven World: Links & Commentary
