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 :
When the price of bread rises, the demand for toasters will likely increase, leading to a shift in the demand curve for toasters. To explain this, let’s break it down:
Explanation:
Toasters and bread are complementary goods. Complementary goods are items that are often used together, meaning an increase in the price of one can impact the demand for the other. In this case, bread and toasters are complementary goods because toasters are typically used to toast bread. If the price of bread increases, consumers will likely purchase less bread, but there may be a greater demand for toasters because people who continue to buy bread may seek to toast it more frequently, or there could be a behavioral shift where consumers substitute other types of bread or prefer toasted bread more.
Thus, a rise in the price of bread can increase the demand for toasters, shifting the demand curve to the right. A rightward shift of the demand curve signifies an increase in demand for toasters at each price level.
Supply-Demand Diagram:
Let’s visualize the supply-demand diagram for toasters:
- Initial Equilibrium: The original demand curve (D1) intersects with the supply curve (S) at the initial equilibrium price (P1) and quantity (Q1).
- Shift in Demand Curve: With the increase in the price of bread, the demand curve for toasters shifts to the right from D1 to D2.
- New Equilibrium: The new demand curve (D2) intersects the supply curve (S) at a higher equilibrium price (P2) and a higher equilibrium quantity (Q2).
This shift shows that as demand for toasters increases due to the rise in bread prices, both the equilibrium price and quantity of toasters increase.
Summary:
- Effect on demand: The demand for toasters increases because they are complementary goods with bread.
- New equilibrium: The equilibrium price and quantity for toasters rise as a result of the shift in demand.
