Price Elasticity of Demand : Price elasticity of demand measures the quantitative response of demand to a change in price. This is the ratio of percentage change in demand to the percentage change in price. So the price elasticity of demand is, Here, ep = price elasticity of demand Here in the above given equation a negative sign has been used as the relation of price and demand is negative. So to avoid negative values the negative sign has been introduced. Example : Considering the price of X commodity is falling to $80 from $100 and the demanded quantity is rising to 3000 units from 1000 units. Thus,
The price elasticity of demand,
Thus, the price elasticity is 100.
