Suppose the elasticity of demand for cereal is 1. If cereal increases in price by 25 percent, the percentage decrease in quantity demanded will be 25%.
What is the elasticity of demand?
- The quantity sought for a good is measured according to its price elasticity of demand.
- Almost all goods see a decrease in quantity demanded when prices rise, however certain goods experience this decrease more than others.
- When a price increases by 1% while all other factors remain constant, the price elasticity provides the percentage change in the quantity required.
- If the elasticity is 2, a 1% increase in price results in a 2% decrease in the amount demanded.
- Other elasticities gauge how changes in other factors affect the quantity needed
- For example - the income elasticity of demand for consumer income changes.
