Why are time series data unlikely to give an accurate estimate of demand?
Demand may have shifted over time, so that instead of obtaining points on a single demand curve, one is connecting points from several demand curves. One needs to obtain several price, quantity points at a single point in time to be assured of an accurate estimate of a single demand curve.
