What can you substitute for elastic?

Elastic is used in economics to define a transformation in buyers' and sellers' behavior due to changes in a commodity or service price.

Demand elasticity or inelasticity is dictated by how much demand for the product varies as the price increases or decreases in the market.

The term elastic can be substituted for perfectly elastic where the percentage of variation in quantity demanded is infinite, even if the price variation is zero since it involves changes in demand due to changes in pricing.
