Measurement of Price Elasticity (Percentage method)
Price elasticity of demand measures how responsive the quantity demanded changes in response to a change in the price of a good or service.
The percentage method involves calculating the percentage change in quantity demanded divided by the percentage change in price. This method allows us to compare the magnitude of the percentage changes in both the quantity demanded and price.
The percentage change in quantity demanded is calculated as:
Percentage change in quantity demanded = (Change in quantity demanded / Original quantity demanded) x 100
Similarly, the percentage change in price is calculated as:
Percentage change in price = (Change in price / Original price) x 100
The price elasticity of demand can be calculated using the following formula:
Price elasticity of demand = Percentage change in quantity demanded / Percentage change in price
For example, if the quantity demanded changes by 10% when the price changes by 5%, the price elasticity of demand would be calculated as:
Price elasticity of demand = 10% / 5% = 2
This means that, on average, for a 1% increase in price, the quantity demanded decreases by 2%.
The price elasticity of demand can be classified into different categories:
Elastic: If the price elasticity of demand is greater than 1, the quantity demanded changes more than the price changes.
Semi-elastic: If the price elasticity of demand is between 0.5 and 1, the quantity demanded changes slightly more than the price changes.
Inelastic: If the price elasticity of demand is less than 0.5, the quantity demanded changes very little in response to changes in price.
The price elasticity of demand is an important tool for understanding how demand responds to changes in price. It can be used to inform business decisions, such as pricing strategies and marketing efforts
