Price Mechanism & its Application (Part II) - Elasticity

The Price Elasticity of Demand (PED) can be a positive value, but less than 1.

• True

• False

Answer explanation

False. The price elasticity of demand coefficient is always negative because the law of demand states that the quantity demanded of a good or service is inversely related to its price. An increase (fall) in price will lead to a fall (increase) in the quantity demanded, ceteris paribus. By convention, the negative sign is often ignored.

How do you calculate price elasticity of supply?

• Price Elasticity of Supply = (% Change in Quantity Supplied) / (% Change in Price)

• Price Elasticity of Supply = (Change in Price) / (Change in Quantity Supplied)

• Price Elasticity of Supply = (Change in Quantity Demanded) / (Change in Price)

• Price Elasticity of Supply = (Change in Quantity Supplied) / (Change in Price)

Price level and consumer preference affects the price elasticity of demand (PED). The higher the price, the higher the PED. Similarly, the stronger the preference, the higher the PED.

• True

• False

Answer explanation

False. The price level of a good does not determine the PED value, since PED value is calculated in 'percentages changes.'

Instead, PED is dependent on the proportion of income, availability and closeness of substitutes, degree of necessity and time period for consumption.

Explain the importance of elasticity in market analysis.

• Elasticity in market analysis is important for understanding consumer and producer behavior in response to price changes, aiding in pricing strategies, demand forecasting, and market evaluation.

• Elasticity in market analysis is irrelevant for pricing strategies

• Market evaluation does not require an understanding of elasticity

• Elasticity does not impact consumer and producer behavior

How does the availability of substitutes affect price elasticity of demand?

• Availability of substitutes increases price elasticity of demand.

• Availability of substitutes decreases price elasticity of demand.

• Availability of substitutes has no impact on price elasticity of demand.

• Availability of substitutes only affects supply, not demand elasticity.

Which of the following is an example of application of cross elasticity of demand (XED)?

• Examining the relationship between price and quantity demanded

• Studying the impact of supply on demand

• Analyzing the elasticity of supply

• Examples of applications of cross elasticity of demand include analyzing the relationship between the demand for related goods when prices change.

Answer explanation

The cross elasticity of demand (XED) measures the responsiveness of the demand of a good to a change in the price of another good, ceteris paribus.

Hence, it is useful for analysing the relationship between the demand for related goods when prices of one good change. E.g. Producers can predict how and to what extend the demand for their goods will change, when price of competitors' good changes.

How does the elasticity of demand vary for different products?

• The elasticity of demand varies for different products based on factors such as availability of substitutes, necessity, brand loyalty, and price relative to income.

• The elasticity of demand is the same for all products

• The elasticity of demand is higher for luxury products compared to essential goods

• The elasticity of demand is only influenced by the price of the product

What role does time play in determining price elasticity of supply?

• Time allows producers to adjust production levels, making supply more elastic in the long run.

• Time decreases the availability of substitutes, affecting supply elasticity.

• Time increases demand, not supply elasticity.

• Time has no impact on price elasticity of supply.

What is the relationship between price elasticity of demand and total revenue?

• No relationship

• Inverse relationship

• Direct relationship

• Positive relationship

Give an example of a product with elastic demand.

• Luxury goods like designer handbags

• Low-cost generic products

• Basic necessities like rice

• Fast-moving consumer goods like toothpaste
