Figure 3.3: FIGURE 3-3 Movement Along the Demand Curve versus Shift of the Demand Curve
Figure 3.3: The rise in quantity demanded when going from point A to point B reflects a movement along the demand curve: it is the result of a fall in the price of the good. The rise in quantity demanded when going from point A to point C reflects a shift of the demand curve: it is the result of a rise in the quantity demanded at any given price.
