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.
Influences the elasticity of demand to a larger extent. The main reason for change in the elasticity of demand with change in price of some goods is the availability of their competing substitutes. The larger the number of close substitutes of a good available in the market, greater the elasticity for that good. For example, tea and coffee are close substitutes.
