Welfare and the Act of Choosing

The standard revealed-preference approach to welfare economics encounters fundamental difficulties when the act of choosing directly affects welfare through emotions such as guilt, pride, and anxiety. We address this problem by developing an approach that redefines consumption bundles in terms of the sensations they produce, and measures welfare by blending choice-based methods with self-reported well-being techniques. In applications to classic social preferences paradigms, our approach shows that standard revealed-preference methods, including those that exploit choices over menus, mismeasure welfare because preferences depend on choice sets, while self-reported happiness and satisfaction are not sufficient statistics for welfare.
