Demand elasticity is the sensitivity of the demand for a good or service due to a change in another factor. There are many factors that influence a change in demand elasticity. These factors include price, income level and availability of substitutes. One factor that can affect demand elasticity of a good or service is its price level. For example, the change in the price level for a luxury car can cause a substantial change in the quantity demanded.
The elasticity of demand (Ed) , also referred to as the price elasticity of demand, measures how responsive demand is to changes in a price of a given good. More precisely, it is the percent change in quantity demanded relative to a one percent change in price, holding all else constant (ceteris paribus). Demand of goods can be classified as either perfectly elastic, elastic, unitary elastic, inelastic, or perfectly inelastic based on the elasticity of demand.
