Value exchange is an important concept in marketing that involves understanding what consumers value and need in exchange for products and services. It is based on the fundamental transaction of exchanging data for better experiences to facilitate commercial transactions and engagement. The concept of exchange value helps marketers position offerings by understanding how consumers evaluate the worth of products compared to alternatives. Perceived conspicuous value and perceived quality value also influence customers, where social and reputational factors drive consumption behaviors across all classes, and perceived ability of products to meet wants and needs determines their success.
