Key Claims

• Behavioral economics is useful when textbook rationality fails to describe how people actually react to money, price, risk, and identity.
• The same amount of money can feel different depending on whether it is framed as loss, gain, compensation, discount, budget, or sunk effort.
• Commercial design often works by arranging reference points: buffets, refills, free services, subsidies, and coupons all change what the buyer thinks they are paying.
• Everyday behavioral economics should improve agency, not become cynical proof that all markets are manipulation.
