Income elasticity of demand vs price elasticity of demand. Price elasticity of demand measures the responsiveness of quantity demanded of a particular product as a result of a change in price levels. However demand for inferior goods will decrease as income increases because consumers will be able to purchase better quality goods instead of purchasing cheap inferior ones. It can be elastic or inelastic for a particular commodity. The other major difference between elasticity of demand and elasticity of supply is that demand and supply respond differently to an increase decrease in price.

Normal goods have a positive income elasticity of demand so as consumers income rises more is demanded at each price i e. The difference between price elasticity of demand and income elasticity of demand is that income elasticity refers to the horizontal shift of the demand curve while price elasticity of demand. Price elasticity of demand and income elasticity of demand are two important calculations in economics. Elasticity of demand is of three types price income and cross.

It should be clear that the measure of the arc elasticity is an approximation of the true elasticity of the section ab of the de mand curve which is used. Price elasticity of demand. It is commonly referred to as. To understand the difference between elastic and inelastic demand see the article.

Demand tends to increase when price falls and supply tends to fall when price falls. They are elasticity is a measure of the average elasticity that is the elasticity at the mid point of the chord that connects the two points a and b on the demand curve defined by the initial and the new price levels figure 2 38.
