A reduction in demand occurs when the quantities of a good or service demanded fall at each price. Here, the demand schedule shows a lower quantity of coffee demanded at each price than we had in Figure 3.1 “A Demand Schedule and a Demand Curve”. The reduction shifts the demand curve for coffee to D3 from D1. The quantity demanded at a price of $6 per pound, for example, falls from 25 million pounds per month (point A) to 15 million pounds of coffee per month (point A?).
A varying that change the quantity of a beneficial otherwise provider necessary at each price is called a demand shifter .
