Understanding Change in Quantity Demanded
In economics, the term "change in quantity demanded" specifically refers to changes in the amount of a good or service that consumers are willing to purchase, primarily due to price fluctuations.
Movement Along the Demand Curve
- A change in quantity demanded is represented by a movement along the demand curve.
- When the price of a good decreases, the quantity demanded typically increases. Conversely, if the price increases, the quantity demanded decreases.
Illustrating Price Changes
- For instance, consider a product priced at $10. If the price drops to $8, consumers may decide to buy more of that product, thus increasing the quantity demanded.
- This change reflects a movement down the demand curve (to the right), rather than shifting the entire curve itself.
Difference from Demand Shifts
- It's important to differentiate this from a "change in demand," which involves a shift of the entire demand curve due to factors like consumer preferences, income changes, or external influences.
- A shift in demand indicates that at every price point, consumers are now willing to buy more or less of the product regardless of price.
Conclusion
- Therefore, option B accurately captures the essence of a change in quantity demanded as it illustrates how price changes directly impact consumer purchasing behavior, while other options describe different economic concepts.
