There is also, and mainly, the "hedonic adjustment" that is made in computing GDP - the price of computing devices, for instance is arbitrarily increased to reflect their increased "power", and this is taken to mean that their value to consumers is increased by the same amount. This year's phone is ten times as "powerful" as one from five years ago, therefore we multiply phone sales by ten. The same reasoning applies with cars, ignoring the fact that it's now nearly impossible to buy a car without power windows, power steering, automatic transmission, anti-lock braking, etc.
