The document introduces the Means-End Chain Model, which assumes that consumers value products based on the ends or abstract values that the products can attain. The model proposes that products have attributes that provide benefits or consequences, which in turn allow consumers to achieve higher-level personal values. It outlines the three levels of the model - attributes, benefits/consequences, and values - and provides examples of how different attributes of products can enable benefits that help consumers achieve values like health, pleasure, and self-respect.
