When prices change from one year to the next, they do not all change proportionately; some prices rise more than others. Consumers respond to these differing prices by buying less. When a new good is introduced, consumers have more variety from which to choose, and this in turn reduces the cost of maintaining the same level of economic well being: unmeasured quality change.
