Price elasticity of supply
The price elasticity of supply (PES or Es) is commonly known as “a measure used in economics to show the responsiveness, or elasticity, of the quantity supplied of a good or service to a change in its price.” Price elasticity of supply, in application, is the percentage change of the quantity supplied resulting from a 1% change in price. Alternatively, PES is the percentage change in the quantity supplied divided by the percentage change in price.
