Price elasticity of demand (PED) measures the degree of responsiveness of the quantity demanded of a good to a given change in price of the good itself, ceteris paribus. It is found by taking the percentage change in quantity demanded of good X divided by the percentage change in the price of good X.
The numerical value of the price elasticity of demand is always negative due to the inverse relationship between quantity demanded and price as stated in the law of demand. When we interpret the value of the price elasticity of demand, we just quote the absolute value. The absolute value of PED range from zero to infinity.
When PED is greater than one, the demand for the good is said to be price elastic. It means that a proportionate change in price causes a more than proportionate change in quantity demanded, ceteris paribus.
When PED is less than one, demand for the good is said to be price inelastic. This means that a proportionate change in price of the good causes a less than proportionate change in quantity demanded, ceteris paribus.
Different products have different price elastic ties due to a number of factors. Firstly the availability and closeness of substitutes. The more easily available and closer the substitutes for the good, the more price elastic will be the demand for the good. The availability of substitutes can be affected by the definition of market and the time span under consideration.
The elasticity of demand in any market depends on how we draw boundaries of the market. Broadly defined goods such as sports shoes tend to have higher price inelastic demand than narrowly defined goods for example Nike sports shoes, because it is more difficult to find good substitutes for sports shoes.
The demand for a product tend to be price inelastic in the short run but becomes more price elastic in the long run. This is because consumers will replace...
