Elasticity of Demand Types

What is price elasticity of demand?

• Price elasticity of demand measures the supply of a good in response to a change in its price.

• Price elasticity of demand refers to the relationship between price and quantity supplied of a good.

• Price elasticity of demand is a measure of how much the quantity demanded of a good changes in response to a change in its price.

• Price elasticity of demand is a term used to describe the quantity supplied of a good.

Define income elasticity of demand.

• Income elasticity of demand is the ratio of total income to total demand in an economy.

• Income elasticity of demand is the percentage change in price divided by the percentage change in quantity demanded.

• Income elasticity of demand is the measure of how much consumers' incomes change due to demand shifts.

• Income elasticity of demand is the percentage change in quantity demanded divided by the percentage change in income.

Explain cross-price elasticity of demand.

• Cross-price elasticity of demand measures the responsiveness of the quantity supplied of one good to a change in the price of another good.

• Cross-price elasticity of demand measures the responsiveness of the quantity demanded of one good to a change in the price of another good.

• Cross-price elasticity of demand is only applicable to substitute goods.

• Cross-price elasticity of demand is used to calculate the total revenue of a firm.

What is meant by perfectly inelastic demand?

• Quantity demanded does not change with price.

• Quantity demanded is not affected by income changes.

• Quantity demanded is perfectly elastic.

• Quantity demanded increases with price.

Describe perfectly elastic demand.

• Perfectly inelastic demand is a situation where the quantity demanded does not change in response to any change in price.

• Perfectly elastic equilibrium is a situation where the market reaches a balance between supply and demand without any excess or shortage.

• Perfectly elastic demand is a situation where the quantity demanded changes infinitely in response to any change in price, while the price remains constant.

• Perfectly elastic supply is a situation where the quantity supplied changes infinitely in response to any change in price, while the price remains constant.

What is unitary elastic demand?

• Unitary elastic demand is when the demand curve is perfectly vertical.

• Unitary elastic demand is when the price changes by the same percentage as the quantity demanded.

• Unitary elastic demand is when the quantity demanded remains constant regardless of price changes.

• Unitary elastic demand is when the quantity demanded changes by the same percentage as the price.

What factors affect price elasticity of demand?

• Price of complementary goods, consumer income, consumer preferences

• Availability of substitutes, necessity of the good, proportion of income spent on the good, time period considered, brand loyalty

How is price elasticity of demand calculated?

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

• Price Elasticity of Demand = (Quantity Demanded) / (Price)

• Price Elasticity of Demand = (Price Change) / (Quantity Change)

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