INSIGHTSElasticity of demand quantifies the sensitivity of consumer demand in response to price changes. Specifically, it is calculated as the percentage change in quantity demanded divided by the percentage change in price. If the elasticity is greater than one, demand is considered elastic, meaning consumers significantly alter their purchasing behavior with price changes. Conversely, if the elasticity is less than one, demand is inelastic, indicating that price changes have a lesser effect on quantity demanded.
For example, a luxury item may exhibit elastic demand; a price increase could lead to a notable decrease in sales. In contrast, essential goods such as food often display inelastic demand, where price fluctuations have a minor impact on consumer purchases. Understanding demand elasticity helps traders and businesses make informed pricing and inventory decisions. Related concepts include price elasticity, income elasticity, and cross-price elasticity, each providing insights into different dimensions of consumer behavior.
