More analysis on Jane Siberry's music store

From the Freakonomics guys:

Even more cleverly, Siberry posts the average payment rate for each song as you pull your payment option from the drop-down menu—another reminder that, Hey, you’re more than welcome to steal this music but here’s how other people have acted in the recent past. Methinks Ms. Siberry grasps the power of incentives quite well. This allows for at least a couple of interesting things to happen: people can decide what to pay after they hear the music, and see how much it’s worth to them (it looks like people generally pay the most per song under this option); and it takes the variable-pricing scheme that economists love and puts it in the hands of the consumer, not the seller.
