Perfectly inelastic
Situation in which the price elasticity of demand is zero
Perfectly Elastic
Situation in which the price elasticity of demand is infinite
Income elasticity of demand
The percentage change in quantity demanded at a specific price divided by the percentage change in income that produced the demand change, all other things unchanged
Cross Price elasticity of demand
It equals the percentage change in the quantity demanded of one good or service at a specific price divided by the percentage change in the price of a related good or service
