how responsive or sensitive consumers are to a change in price
What are the three types of elasticity of demand?
elastic, inelastic, unitary
What is when the consumers are relatively responsive to a change in price and the percentage change of quantity demanded is greater than the percentage change in price?
elastic: price elasticity of demand
What is when the consumers are relatively unresponsive to a change in price and the percentage change in quantity demanded is less than the percentage change in price?
inelastic: price elasticity of demand
What is when the consumer's demand is equal to the percentage change in price?
unitary: price elasticity of demand
What is when consumers are completely unresponsive to a price change and the equity demanded equals zero?
perfectly inelastic
What is when consumers are completely responsive to a price change and firms can sell as much as it wants at a constant price? The equity demanded is infinite.
perfectly elastic
The total revenue method states that if demand price is elastic, then price and total revenue move in the ______ direction.
opposite
The total revenue method states that if demand price is inelastic, then price and total revenue move in the ______ direction.
same
The total revenue method states that if demand price is unitary, then a change in price ______ total revenue.
does not change
What are the determinants of price elasticity of demand?
proportion (%) of consumers income or budget spend on a product, number of close substitutes available, type of product, amount of time consumer has to adjust to price change
What measures how responsive or sensitive producers are to a change in price?
price elasticity of supply
What is when producers are relatively responsive to a change in price and the quantity supplied is greater than zero?
elastic: price elasticity of supply
What is when producers are relatively unresponsive to a change in price and the quantity supplied is less than zero?
inelastic: price elasticity of supply
What is when the percentage change in quantity supplied is equal to the percentage change in price?
unitary: price elasticity of supply
What is when the producer is completely responsive to a price change, and the supply curve is parallel to the quantity axis?
perfectly elastic: supply
What is when the producer is completely unresponsive to a price change, and the supply curve is parallel to to the price axis?
perfectly inelastic: supply
What is the determinant of price elasticity of supply?
The amount of time producers have to adjust resources in response to price change. The longer the time period, the greater the price elasticity of supply.
