What is composite demand?

When one good is demanded for two or more different uses.

Give one example of a good with composite demand.

Crude oil is used for petrol and for making plastics.

Why do different uses compete when a good has composite demand?

Because the same limited good must be shared, so more for one use means less for others.

If demand for one use rises but supply stays the same, what happens to the price of the good?

The price rises for all uses because total demand is higher.

When a new use is found for a good, what happens to its market demand curve?

It shifts to the right, because total demand increases.

When milk is used to make cheese, what is given up in other uses?

Using that milk for drinking or for other dairy goods.

How is composite demand different from joint demand?

Composite demand is one good with many uses. Joint demand is two goods used together, like printers and ink.

How is composite demand different from derived demand?

Composite demand is one good wanted for many uses. Derived demand is demand for something because another good is wanted, like workers to make cars.

If the government subsidises one use of a good with composite demand, what might happen to other uses?

Total demand rises, so the price may rise and less is left for other uses.

If one use disappears, what happens to the demand for the good?

Total demand falls, the demand curve shifts left, and the price may fall.
