ELASTICITY: The relative response of one variable to changes in another variable. The phrase "relative response" is best interpreted as the percentage change. For example, the price elasticity of demand, one of the more important applications of this concept in economics, is the percentage change in quantity demanded measured against the percentage change in price. Other notable economic elasticities are the price elasticity of supply, income elasticity of demand, and cross elasticity of demand.
