No. There are lots of other things you CAN do with SSH that people don't do that often. > > Do you have any actual > > data or did you just pull 2-5 out of the air? > > > There is a middle ground between data and the air, > which is analysis.

Elasticity is about how much consumption changes when price changes, not about what people who were already going to buy choose to buy. Look at it this way: If Pepsi cut their price by 50%, it might affect their market share but would have only a very small amount of effect on how much fluid people consume overall. The market for beverages is competitive but not particularly elastic. That could easily be happening here. Ian, it's a major econometrics project to determine how elastic a given good has. To imagine that you can do it with a little handwaving is simply naive. -Ekr -- [Eric Rescorla [EMAIL PROTECTED] http://www.rtfm.com/ --------------------------------------------------------------------- The Cryptography Mailing List Unsubscribe by sending "unsubscribe cryptography" to [EMAIL PROTECTED]
