Fuzzy Choice Functions

The book delves into welfare economics, focusing on consumer rationality in decision-making amidst varying prices and incomes. It explores the theory of consumption, emphasizing how consumers establish preferences among commodity bundles to make optimal choices within budget constraints. Key concepts include Samuelson's theory of revealed preference and the foundational Weak and Strong Axioms of Consumer Behavior. The discussion extends beyond consumer choices, illustrating rational decision-making across various fields such as economics, social life, and psychology, including voting behavior in elections.
