In , author Matthew D. Adler provides readers with a comprehensive, philosophically grounded argument for the use of social welfare functions as a framework for governmental policy analysis--a framework that is welfarist but not utilitarian, and sensitive to the distribution of human well-being.

addresses a range of relevant theoretical issues, including the nature of well-being and the possibility of interpersonal welfare comparisons; the moral value of equality, and how that bears on the form of the social welfare function; social choice under uncertainty; and the integration of individual responsibility into the social-welfare function approach. Adler also explores issues of implementation by looking at how survey data and other sources of evidence might be used to calibrate both a well-being metric and a social welfare function, and discussing whether distributive goals are ever best pursued through regulation rather than the tax system. In working through this range of theoretical and practical issues, draws from a wide variety of literatures, including philosophical scholarship on equality, "prioritarianism," responsibility, 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-analytic scholarship on cost-benefit analysis, environmental justice, and the choice between regulation and taxation; and the burgeoning field of "happiness studies."
