What happens to the demand curve for toasters if the price of bread rises? Show in a supply-demand diagram how the equilibrium price and quantity of toasters change.
The correct answer and explanation is :
If the price of bread rises, the demand for toasters will likely increase. To understand why, it’s essential to recognize the relationship between goods that are complements, such as bread and toasters. Complements are products that are consumed together, so when the price of one good rises, it can affect the demand for the other. In this case, bread and toasters are complementary goods because people often use toasters to prepare bread, particularly in the form of toast.
Explanation:
- Complementary Goods: When the price of bread rises, people may continue to buy bread, but since toasters are used to prepare bread, they might also increase their demand for toasters. The rise in bread prices could make people want to enjoy more toast, increasing the need for a toaster. Therefore, the demand curve for toasters shifts to the right, indicating a higher quantity of toasters demanded at each price.
- Demand Curve Shift: In economic terms, an increase in the price of one complement (bread) causes the demand for the related product (toasters) to increase. The demand curve for toasters shifts to the right from D1 to D2.
- Equilibrium Changes: The increase in demand for toasters causes a new equilibrium to be established. As the demand curve shifts rightward, the quantity of toasters demanded at the initial price exceeds the quantity supplied. This creates upward pressure on the price of toasters. As a result, the equilibrium price of toasters rises, and the equilibrium quantity of toasters also increases. This can be shown in a supply-demand diagram, where the new equilibrium price and quantity are at a higher point compared to the original equilibrium.
Supply-Demand Diagram Explanation:
- Initial equilibrium: The supply and demand curves intersect at a point where the equilibrium price (P1) and quantity (Q1) are determined.
- New demand curve (D2): When the price of bread rises, the demand curve for toasters shifts rightward from D1 to D2, leading to a higher equilibrium price (P2) and quantity (Q2) of toasters.
Conclusion:
The increase in the price of bread leads to a rightward shift in the demand curve for toasters, resulting in an increase in both the equilibrium price and quantity of toasters.
