4. According to the revision sheet, what is the Law of Demand?

A. Averse relationship between price and quantity demanded.

B. Direct relationship between price and quantity demanded.

C. Inverse relationship between price and quantity demanded.

D. No relationship between price and quantity demanded.

Answer: (C)

Spiegazione

The Law of Demand states there is an inverse relationship between price and quantity demanded, meaning as price decreases, demand increases.

5. At market equilibrium, which of the following is true?

A. Prices are fixed and do not change.

B. Quantity demanded exceeds quantity supplied.

C. Quantity supplied exceeds quantity demanded.

D. The price adjusts so that quantity demanded equals quantity supplied.

Answer: (D)

Spiegazione

Market equilibrium occurs when the quantity demanded equals the quantity supplied, and the price adjusts to reach this point, clearing the market of shortages or surpluses.

6. What causes the demand curve to shift to the right according to the revision sheet?

A. An increase in consumer income.

B. A decrease in the price of the good itself.

C. A rise in input costs for producers.

D. A technological regression.

Answer: (A)

Spiegazione

An increase in consumer income can lead to higher demand, shifting the demand curve to the right. The other options generally cause movements along the curve or shifts in supply.

7. Which of the following factors influences the shift of supply curves?

A. Input costs, technology, natural events, expectations.

B. Consumer tastes and income levels.

C. Prices of related goods demand.

D. Number of buyers in the market.

Answer: (A)

Spiegazione

Supply curves shift due to factors like technology, input costs, natural events, and expectations. Consumer tastes primarily affect demand.

8. What does the Price Elasticity of Demand (PED) measure?

A. The responsiveness of demand to changes in income.

B. The responsiveness of demand to changes in price.

C. The overall slope of the demand curve.

D. The responsiveness of supply to changes in price.

Answer: (B)

Spiegazione

PED measures how much demand responds to price changes, indicating demand elasticity or rigidity.

9. What is the market condition called when the quantity supplied exceeds the quantity demanded at a given price?

A. A surplus.

B. A shortage.

C. Market equilibrium.

D. Price floor.

Answer: (A)
