#1
2. Which factor does NOT affect the elasticity of demand?
Consumer preferences
ExplanationUnlike factors such as price and substitutes, consumer preferences do not directly impact demand elasticity.
#2
10. What is the key determinant of the elasticity of supply?
Time period
ExplanationThe time period is a key determinant of supply elasticity, as it influences the ability of producers to adjust their production levels.
#3
20. The concept of elasticity is equally applicable to both demand and:
Supply
ExplanationElasticity is equally applicable to both demand and supply, helping analyze the responsiveness of quantity to changes in price.
#4
1. What is elasticity of demand?
The measure of responsiveness of quantity demanded to a change in price
ExplanationIt gauges how much the quantity demanded changes in response to a change in price.
#5
3. If the cross-price elasticity of two goods is positive, it indicates that they are:
Substitute goods
ExplanationA positive cross-price elasticity suggests that an increase in the price of one good leads to an increase in demand for the other, indicating substitution.
#6
5. The concept of income elasticity of demand is important in understanding the impact of changes in:
Consumer income
ExplanationIt focuses on how changes in consumer income affect the quantity demanded for a good.
#7
7. In the context of elasticity, what does the term 'unitary elastic' mean?
Percentage change in quantity demanded equals percentage change in price
ExplanationUnitary elastic describes a situation where the percentage change in quantity demanded is exactly equal to the percentage change in price.
#8
9. The concept of cross-price elasticity is particularly relevant for which type of goods?
Substitute goods
ExplanationCross-price elasticity is crucial for substitute goods, as it measures how the price change of one good affects the quantity demanded for another.
#9
4. What is the formula for calculating the price elasticity of demand?
PED = (Q2 - Q1) / (P2 - P1)
ExplanationPrice Elasticity of Demand (PED) is calculated by dividing the percentage change in quantity demanded by the percentage change in price.
#10
6. What does a perfectly elastic demand curve look like?
Horizontal line
ExplanationA perfectly elastic demand curve is represented by a horizontal line, indicating consumers are willing to buy any quantity at a specific price.
#11
8. If the price of a good increases by 10% and the quantity demanded decreases by 5%, what is the price elasticity of demand?
2.0
ExplanationThe price elasticity of demand is calculated as the percentage change in quantity demanded divided by the percentage change in price, which in this case is 5% / 10% = 0.5. The absolute value of this ratio is 2.0.
#12
12. Which of the following is an example of a necessity with an inelastic demand?
Bottled water
ExplanationNecessities like bottled water often have inelastic demand, meaning consumers are less responsive to price changes.
#13
14. How does the elasticity of demand vary along a linear demand curve?
Increases
ExplanationElasticity of demand tends to increase along a linear demand curve, with different sections having varying degrees of responsiveness.
