Q9. Consider butter and margarine, which are substitutes. When the price of butter falls, the demand curve for margarine is likely to:

Background

Topic: Substitutes and Demand Shifts

This question tests your understanding of how the demand for one good changes when the price of a substitute changes.

Key Terms:

• Substitute Goods: Goods that can replace each other in consumption.

• Demand Curve Shift: A change in demand at every price, represented by a shift of the curve.

Step-by-Step Guidance

1. Recall what happens to the demand for a good when the price of its substitute falls.

2. Think about consumer behavior: if butter becomes cheaper, what happens to the demand for margarine?

3. Identify which direction the demand curve for margarine will shift.

Q11. Suppose that some resource X is necessary to produce some good Y. If the price of X falls, what happens?

Background

Topic: Input Prices and Supply

This question tests your understanding of how changes in input prices affect the supply of a good.

Key Terms:

• Input (Resource): A factor used in the production of goods or services.

• Supply Curve: Shows the relationship between price and quantity supplied.

Step-by-Step Guidance

1. Recall how a decrease in the price of an input affects the cost of producing the final good.

2. Think about whether this change would shift the supply curve for the final good, and in which direction.

3. Eliminate answer choices that do not relate to the supply of the final good.

Q15. Suppose that supply for some good increases and that simultaneously the demand for the same good decreases. The result would be:

Background

Topic: Simultaneous Shifts in Supply and Demand

This question tests your ability to predict changes in equilibrium price (P) and quantity (Q) when both supply and demand curves shift.

Key Terms:

• Equilibrium Price (P): The price at which quantity supplied equals quantity demanded.

• Equilibrium Quantity (Q): The quantity bought and sold at the equilibrium price.

Step-by-Step Guidance

1. Recall what happens to equilibrium price and quantity when supply increases (holding demand constant).

2. Recall what happens when demand decreases (holding supply constant).

3. Combine the effects to determine the overall impact on price and quantity.

4. Remember that one effect may be indeterminate without more information.

Q16. Suppose that in Montreal in December, 2018, 10,000 ski helmets were sold at a price of $60 each. And in Montreal in December, 2019, 20,000 ski helmets were sold at a price of $80 each. One possible explanation for the change is that, ceteris paribus, from 2018 to 2019 the ________ curve for ski helmets shifted to the ________.
