It’s hard to overstate the importance of understanding the difference between shifts in curves and movements along curves. Remember, when we talk about changes in demand or supply, we do not mean the same thing as changes in quantity demanded or quantity supplied ..

A change in demand refers to a shift in the entire demand curve, which is caused by a variety of factors (preferences, income, prices of substitutes and complements, expectations, population, etc.). In this case, the entire demand curve moves left or right:.

A change in quantity demanded refers to a movement along the demand curve, which is caused only by a chance in price. In this case, the demand curve doesn’t move; rather, we move along the existing demand curve:.

Similarly, a change in supply refers to a shift in the entire supply curve, which is caused by shifters such as taxes, production costs, and technology. Just like with demand, this means that the entire supply curve moves left or right:.

A change in quantity supplied refers to a movement along the supply curve, which is caused only by a change in price. Similar to demand, a change in quantity supplied means that we’re moving along the existing supply curve:.

Here’s one way to remember: a movement along a demand curve, resulting in a change in quantity demanded, is always caused by a shift in the supply curve. Similarly, a movement along a supply curve, resulting in a change in quantity supplied, is always caused by a shift in the demand curve..
