Elasticity (economics)

Price elasticity of demand = -2

Price elasticity of demand measures how much the quantity demanded of a good responds to a change in price. A price elasticity of -2 indicates that for every 1% increase in price, the quantity demanded decreases by 2%. This concept helps to understand consumer behavior in response to price changes.

Example

If the price elasticity of demand for a product is -2, and the price increases by 10%, the quantity demanded will decrease by 20%.

Understanding price elasticity is crucial for businesses and policymakers to predict changes in demand and make informed decisions about pricing strategies and tax policies.
