3.1.2.6 The interrelationship between markets NOTES

What does the term "joint demand" refer to in economics?

• The demand for products that are used independently of each other.

• The demand for products that are used together, such that an increase in demand for one increases the demand for the other.

• The demand for a product that decreases as the price of another product decreases.

• The demand for products that are unrelated in use and consumption.

Which of the following best describes the concept of "demand for substitute goods"?

• Demand for goods that decreases when the price of another good decreases.

• Demand for goods that increases when the price of another good increases.

• Demand for goods that increases when the price of a complementary good increases.

• Demand for goods that increases when the price of another good increases, because the goods are interchangeable.

What is "composite demand"?

• Demand for a good that is influenced by its use in multiple different products.

• Demand for a good that is only used for one specific purpose.

• Demand for a good that is unaffected by market changes.

• Demand for a good that is derived from the demand for a related service.

"Derived demand" refers to the demand for a good or service that arises from:

• The direct consumption or use of the good itself.

• The demand for another good or service.

• The supply of substitute goods.

• The price elasticity of the good.

What does "joint supply" mean in the context of economics?

• The supply of a product that decreases as the supply of another increases.

• The supply of a product that is unaffected by changes in market conditions.

• The supply of two or more products that are produced from the same resources.

• The supply of products that are completely independent of each other.

How might a change in the market for electric cars impact the market for lithium batteries?

• It would have no impact since they are unrelated markets.

• It could decrease the demand for lithium batteries as electric cars are not dependent on these batteries.

• It could increase the demand for lithium batteries due to derived demand.

• It could decrease the demand for gasoline, which is unrelated to lithium batteries.

If there is an increase in the price of beef, what is the likely effect on the demand for chicken, assuming chicken is a substitute for beef?

• Demand for chicken will decrease.

• Demand for chicken will increase.

• Demand for chicken will remain unchanged.

• Demand for chicken will fluctuate unpredictably.

What effect does an increase in the demand for new houses typically have on the market for construction materials?

• Decreases the demand for construction materials.

• Increases the demand for construction materials.

• Has no effect on the demand for construction materials.

• Decreases the supply of construction materials.

In the context of joint supply, if the production of wool increases, what is a likely effect on the supply of mutton?

• The supply of mutton will decrease.

• The supply of mutton will increase.

• The supply of mutton will remain unchanged.

• The supply of mutton will become more expensive.

Which scenario exemplifies composite demand?

• Demand for sugar increases as more people start baking at home.

• Demand for smartphones decreases as the price of tablets decreases.

• Demand for petrol increases as the number of cars increases.

• Demand for steel increases due to its use in both automobiles and construction.
