№3 слайд![Price Elasticity of Demand](/documents_6/919252bdab825e89b7228a6646ae83e1/img2.jpg)
Содержание слайда: Price Elasticity of Demand
Price elasticity of demand is the percentage change in quantity demanded given a percent change in the price.
It is a measure of how much the quantity demanded of a good responds to a change in the price of that good.

Price Elasticity of Demand
Demand tends to be more elastic :
if the good is a luxury.
the longer the time period.
the larger the number of close substitutes.
the more narrowly defined the market.

Содержание слайда: Summary
Price elasticity of demand measures how much the quantity demanded responds to changes in the price.
If a demand curve is elastic, total revenue falls when the price rises.
If it is inelastic, total revenue rises as the price rises.
