In economics, a specific condition arises when the percentage change in quantity demanded or supplied is exactly equal to the percentage change in price. This situation indicates that total revenue remains constant regardless of price fluctuations. For example, if a product’s price increases by 10%, the quantity demanded decreases by 10%, leaving the total revenue unchanged.
Understanding this concept is crucial for businesses in pricing strategies. It allows them to anticipate how changes in price will affect their revenue and make informed decisions accordingly. Historically, recognizing this relationship has been vital in competitive markets where accurately predicting consumer response to price alterations is essential for profitability and market share maintenance.
