When quantity demanded decreases in response to a change in price:

Question

BlackTom AI · Accepted Answer

The question asks about what happens to quantity demanded when price changes and causes a decrease in quantity demanded.
Option: 'there is a movement up along the demand curve.' When the price of a good changes, holding all else constant, the quantity demanded responds along the same demand curve. A higher price leads to a smaller quantity demanded, which is represented as movement up and to the left along the demand curve; a lower price leads to a larger quantity demanded, moving down along the curve.
This behavior reflects the law of demand: inverse relationship between price and quantity demanded, with the demand curve itself remaining stationary.
Note that a shift of the entire demand curve would occur if a non-price determinant changed (for example, income, prices of related goods, tastes, expectations, or the number of buyers). In such cases, the quantity demanded at every price would change, causing the curve to shift rather than a movement along it.
Since the question specifies a change in price causing a decrease in quantity demanded, the appropriate description is a movement along the demand curve rather than a shift of the curve.
