This book addresses a range of relevant theoretical issues, including the possibility of an interpersonally comparable measure of well-being, or “utility” metric; the moral value of equality, and how that bears on the form of the social welfare function; social choice under uncertainty; and the possibility of integrating considerations of individual choice and responsibility into the social-welfare-function framework. This book also deals with issues of implementation, and explores how survey data and other sources of evidence might be used to calibrate (...) both a utility metric and a social welfare function, and whether distributive goals are ever best pursued through regulation rather than the tax system. In working through this range of theoretical and practical issues, the book draws from a wide variety of literatures, including philosophical scholarship on equality, responsibility, the nature of well-being, and personal identity over time; the social choice literature within economics; applied economic literatures concerning the measurement of inequality and poverty; legal and policy-analysis scholarship on cost-benefit analysis, environmental justice, and the choice between regulation and taxation; and the burgeoning field of “happiness studies”.

This Article provides a comprehensive, critical overview of proposals to use happiness surveys for steering public policy. Happiness or “subjective well-being” surveys ask individuals to rate their present happiness, life-satisfaction, affective state, etc. A massive literature now engages in such surveys or correlates survey responses with individual attributes. And, increasingly, scholars argue for the policy relevance of happiness data: in particular, as a basis for calculating aggregates such as “gross national happiness,” or for calculating monetary equivalents for non-market goods based (...) on coefficients in a happiness equation. But is individual well-being equivalent to happiness? The happiness literature tends to blur or conflate important concepts: well-being, subjective well-being, happiness, utility, satisfaction. A preference-realization account of well-being denies the equivalence of happiness and welfare, since someone can have preferences for non-mental attributes, such as health, autonomy, goal-fulfillment, knowledge or the quality of her relationships. It is critical, therefore, to differentiate two potential policy roles for happiness surveys. First, the survey response may provide prima facie evidence of the respondent’s preference-utility: the extent to which her preferences are realized. Second, it may indicate her experience-utility: the quality of her mental states. The Article clarifies these two, very different, ideas. It then criticizes, in turn, the preference-utility and the experience-utility defenses of the policy relevance of happiness surveys. Enthusiasm about happiness is premature. (shrink)
