Change in demand vs. a change in quantity demanded
Distinguish between a change in demand vs. a change in quantity demanded: What factors besides price could cause a shift in the overall demand curve for cupcakes? (e.g., income levels, popularity of cupcakes)
Explain how this scenario might affect the supply of cupcakes: How might existing bakeries react? Would there be incentive for new entrants into the cupcake market? How would these changes be reflected in the supply curve?
Market Equilibrium: At the new equilibrium price point, why will the quantity demanded equal the quantity supplied?
Government Intervention: Suppose the local government, concerned about affordability, sets a price ceiling below the equilibrium price. Using graphs, illustrate the effects of this price ceiling on the market for cupcakes.
Who benefits and who suffers from the price ceiling?
Are there any potential unintended consequences?
Sample Answer
Change in Demand vs. Change in Quantity Demanded
A change in quantity demanded refers to a movement along a given demand curve, caused solely by a change in price. For instance, if the price of cupcakes decreases, consumers will demand a larger quantity at each price point. This is represented by a movement along the demand curve.
A change in demand refers to a shift of the entire demand curve, caused by factors other than price. These factors can include:
- Changes in consumer income: If consumer income increases, demand for normal goods like cupcakes will increase, shifting the demand curve to the right.
- Changes in consumer preferences: If cupcakes become more popular or trendy, demand will increase, shifting the demand curve to the right.
