Common Questions Covered in the Answer Key

Sample Multiple-Choice Question

Q: Which of the following best describes the law of demand?

a) As the price of a good increases, demand increases.

b) As the price of a good increases, demand decreases.

c) Demand and supply are unrelated.

d) Demand is only affected by consumer income.

A: b) As the price of a good increases, demand decreases.

Explanation: The law of demand states that, all else being equal, there is an inverse relationship between price and quantity demanded.

Sample Short-Answer Question

Q: Explain how a subsidy affects the supply curve.

A: A subsidy increases producers' revenues, which lowers production costs. As a result, the supply curve shifts to the right, indicating an increase in supply. This shift tends to lower prices and increase quantity supplied.

Numerical Problem Example

Q: If the price of a product drops from $10 to $8, and the quantity demanded increases from 50 units to 70 units, calculate the price elasticity of demand.

Solution:

1. Calculate the percentage change in quantity demanded:

\[(70 - 50) / 50 = 0.4\ or\ 40%\]

2. Calculate the percentage change in price:

\[(8 - 10) / 10 = -0.2\ or\ -20%\]

3. Elasticity = (% change in quantity demanded) / (% change in price)

\[0.4 / -0.2 = -2\]

Interpretation: The absolute value of elasticity is 2, indicating elastic demand.
