I mean "good" as in "what someone desires", not whether it adequately fits some model. The reason is: If someone defines a particular price increase as "good", that person will try to manipulate the underlying model.

They still want it...and so they can still get it by artificially introducing more buyers into the market. Utter insanity. [1] A gross simplification.
