We examine how different welfarist frameworks evaluate the social value of mortality risk-reduction. These frameworks include classical, distributively unweighted cost-benefit analysis—i.e., the “value per statistical life” (VSL) approach—and three benchmark social welfare functions (SWF): a utilitarian SWF, an ex ante prioritarian SWF, and an ex post prioritarian SWF. We examine the conditions on individual utility and on the SWF under which these frameworks display the following five properties: i) wealth sensitivity, ii) sensitivity to baseline risk, iii) equal value of risk reduction, iv) preference for risk equity, and v) catastrophe aversion. We show that the particular manner in which VSL …

This short comment argues that both cost-benefit analysis (CBA) and cost-effectiveness analysis (CEA) should be seen as imperfect tools for evaluating health policy. This is true, not only for extra-welfarists, but even for welfarists, since both CBA and CEA can deviate from the use of social welfare functions (SWF). A simple model is provided to illustrate the divergence between CBA, CEA, and the SWF approach. With this insight in mind, the comment considers the appropriate role of contingent-valuation studies.
