PED and PES Flashcards
what is PED?
Responsiveness of quality demanded to a change in price
What is the equation for PED/PES?
%Change in Quantity/%Change in Price
What is perfectly inelastic?
any %change in price, no %change in quantity
What is inelastic?
%Change in Quantity < %Change in Price
What is elastic?
%Change in Quantity > %Change in Price
What is perfectly elastic?
any %change of quantity, no %change in price
What is PES?
responsiveness of quantity supplied to a change in price
What does it mean when the PED/PES is more than one?
It’s Elastic
What does it mean when the PED/PES is less than one?
It’s Inelastic
What is Unitary PED/PES?
When the Price Elasticity is 1, and the %Change in Quantity is equal to the Percentage Change in Price
What is the Formula for Percentage Change?
((New Value - Old Value)/Old Value)*100
