# Price Discrimination
Who / What
Price discrimination is a **microeconomic pricing strategy** employed by firms to maximize profits by charging different prices for the same or similar goods/services based on perceived market segments, such as willingness-to-pay and demand elasticity. Unlike product differentiation (where variations exist in production costs), price discrimination focuses solely on varying customer-relative value rather than physical differences.

Background & History
Price discrimination emerged as a theoretical concept in economic theory, rooted in the study of imperfect competition and consumer behavior. Early discussions appeared in the late 19th century with contributions from economists like Alfred Marshall and later formalized by Edward Chamberlin and Joan Robinson in the mid-20th century. The strategy became widely recognized as a practical tool for firms to exploit market inefficiencies, particularly in industries where demand curves varied across segments (e.g., airlines charging business vs. leisure travelers). Modern applications include digital platforms, subscription models, and dynamic pricing systems.

Why Notable
Price discrimination is significant because it allows firms to capture additional revenue by aligning prices with individual buyers’ willingness-to-pay, rather than relying solely on marginal cost. This strategy enhances profitability in competitive markets where price-sensitive demand exists (e.g., airlines, streaming services). Its ethical implications—including concerns about fairness and market power—spark ongoing debates in antitrust policy and consumer protection.
