THE PRICE ELASTICITY OF DEMAND

The price elasticity of demand is the percentage change in the quantity of a good demanded divided by the corresponding change in its price.

Whenever economists speak of the demand elasticity they mean the price elasticity of demand.

If 1 per cent price increase reduces the quantity demanded by 2 per cent, the demand elasticity is — 2. If a price fall of 4 per cent increases the quantity demanded by 2 percent, the demand elasticity is — 1/2, since the quantity change of 2 per cent is divided by the price change of — 4 per cent.

Demand is elastic if the price elasticity is more than 1. In other words, we say that the demand elasticity is high when it is a large number. The quantity demanded is then very sensitive to the price.

We say that the demand elasticity is low when it is a small number and the quantity demanded is relatively insensitive to the price. So, demand is inelastic if the price elasticity lies between 0 and 1.

The relation between demand elasticity and total spending can equally be applied to any problem. Total spending is equal to the price multiplied by the quantity demanded. If we know the demand elasticity, then we know in which direction to change price in order to increase profits. If elasticity of demand is more than 1, then a rise in price will reduce total profit. Conversely, if the demand elasticity is less than 1, raising prices will improve revenue.
