Movement along the Supply Curve
A movement along the supply curve occurs when the only thing that changes is the price of that particular good.
The diagrams referred to in this section are from the Biz/ed Demand and Supply PowerPoint.
Pay particular attention to Slide 11 in the presentation
The effect of a movement can be illustrated in these diagrams.
When the price falls from P1 to P2, the quantity supplied decreases from Q1 to Q2.
When the price rises from P1 to P2, the quantity supplied increases from Q1 to Q2.
Remember: the only thing which has changed is the price of the good. Everything else remains the same.
