An increase in the price of petrol causes a decline in the market demand for motor cars, whereas an expansion in motor car manufacturing leads to a higher demand for steel. What types of demand are illustrated by petrol for cars, and steel for car production, respectively?
- Joint demand and derived demandAnswer
- BCompetitive demand and joint demand
- CDerived demand and composite demand
- DComposite demand and competitive demand
Answer
The demand relationship between petrol and cars is joint (complementary) demand, while the demand for steel used in vehicle manufacturing is derived demand.
Petrol and motor cars are complementary goods consumed together to provide transportation, making their relationship an example of joint demand. Conversely, steel is an intermediate input whose demand depends directly on the production volume of finished motor cars, which represents derived demand.
