Introduction to Elasticities
Elasticity is an economic concept which refers to the responsiveness among consumers or producers to a change in a variable which affects either the market demand or the market supply.
There are four types of elasticity that we will study in this unit:
• Price Elasticity of Demand (PED): Measures the responsiveness of consumers of a particular good to a change in the good’s price.
• Cross-price elasticity of Demand (XED): Measures the responsiveness of consumers of one good to a change in the price of a related goo (either a substitute or a complement).
• Income Elascity of Demand (YED): Measures the responsiveness of consumers of a particular good to a change in their income.
• Price elasticity of Supply (PES): Measures the responsiveness of producers of a particular good to a change in the price of that good.
