PED and Determinants of Elasticity

Calculate the price elasticity of demand when the price increases by 10% and the quantity demanded decreases by 20%.

• 0.5

• 1.5

• 3

• -2

How do determinants such as availability of substitutes and necessity affect the price elasticity of demand?

• Availability of substitutes makes demand more elastic, while necessity makes demand more inelastic.

• Availability of substitutes makes demand more elastic, while necessity has no impact on price elasticity of demand.

• Availability of substitutes makes demand more inelastic, while necessity makes demand more elastic.

• Availability of substitutes has no impact on price elasticity of demand, while necessity makes demand more elastic.

If the price elasticity of demand for a product is -2.5, how would you interpret this coefficient?

• The price elasticity of demand is 2.5, indicating that consumers are not sensitive to price changes.

• The demand for the product is relatively inelastic, meaning that consumers are not responsive to price changes.

• The coefficient indicates that the demand for the product is perfectly elastic, meaning that any price change will result in no change in quantity demanded.

• The demand for the product is relatively elastic, meaning that consumers are very responsive to price changes.

Calculate the price elasticity of demand when the price decreases by 5% and the quantity demanded increases by 15%.

• Price elasticity of demand = (15% / 5%) = 0.75

• Price elasticity of demand = (15% / -5%) = -3

• Price elasticity of demand = (5% / -15%) = -0.33

• Price elasticity of demand = (15% / 5%) = 3

Discuss the impact of income level on the price elasticity of demand for luxury goods versus necessity goods.

• The impact of income level on the price elasticity of demand is that for luxury goods, the elasticity tends to be higher, while for necessity goods, the elasticity tends to be lower as income level increases.

• The impact of income level on price elasticity is the same for luxury and necessity goods

• Luxury goods have lower price elasticity as income level increases

• Necessity goods have higher price elasticity as income level increases

If the price elasticity of demand for a product is 0.8, how would you interpret this coefficient?

• The demand for the product is perfectly elastic.

• The demand for the product is inelastic.

• The demand for the product is unitary elastic.

• The demand for the product is elastic.

In what ways can businesses use the concept of elasticity to make pricing and production decisions?

• By analyzing price elasticity of demand, businesses can make informed decisions about pricing strategies and production levels.

• By assuming that demand is always perfectly elastic

• By ignoring the concept of elasticity and setting prices randomly

• By only focusing on production levels and ignoring pricing strategies

Explain how the availability of substitutes affects the price elasticity of demand.

• The availability of substitutes makes demand more elastic, as consumers have more options to switch to if the price of the product increases.

• The availability of substitutes makes demand more inelastic, as consumers have fewer options to switch to if the price of the product increases.

• The availability of substitutes has no impact on price elasticity of demand.

• The availability of substitutes makes demand more elastic, as consumers are not affected by the price changes of the product.

Explain how the concept of elasticity can help businesses in making pricing decisions.

• By analyzing price elasticity of demand, businesses can make informed decisions about pricing strategies and maximize their revenue.

• Businesses do not need to consider elasticity when making pricing decisions.

• By assuming that demand is always perfectly elastic, businesses can set any price they want.

• By ignoring the concept of elasticity and setting prices randomly, businesses can attract more customers.
