What does price elasticity of demand measure?

• A. The responsiveness of quantity supplied to changes in price
• B. The responsiveness of quantity demanded to a change in price
• C. The effect of minimum prices on demand
• D. Consumer preferences over time

Answer: (B)

Price elasticity of demand measures how sensitive the quantity demanded of a good or service is to a change in its price. This concept is critical in understanding consumer behavior, as a high elasticity indicates that consumers will significantly change their purchasing habits in response to price changes. Conversely, low elasticity suggests that demand remains relatively stable despite price fluctuations. For example, if the price of a product decreases, a highly elastic demand means that a large number of consumers will buy much more of that product. Conversely, if demand is inelastic, a change in price will result in a smaller proportionate change in the quantity demanded. Understanding this relationship helps businesses and economists predict how alterations in pricing will impact overall sales and revenue. The other options address different concepts that are not the main focus of price elasticity of demand.
