Equity By The Numbers: Measuring Poverty, Inequality, And Injustice, Matthew D. Adler

Faculty Scholarship

Can we measure inequity? Can we arrive at a number or numbers capturing the extent to which a given society is equitable or inequitable? Sometimes such questions are answered with a “no”: equity is a qualitative, non-numerical consideration.

This Article offers a different perspective. The difficulty with equity measurement is not the impossibility of quantification, but the overabundance of possible metrics. There currently exist at least four families of equity-measurement frameworks, used by scholars and, to some extent, governments: inequality metrics (such as the Gini coefficient), poverty metrics, social-gradient metrics (such as the concentration index), and equity-regarding social welfare functions. …

The Social Value Of Mortality Risk Reduction: Vsl Vs. The Social Welfare Function Approach, Matthew D. Adler, James K. Hammitt, Nicolas Treich

Faculty Scholarship

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 various social welfare functions (SWFs). The SWFs are either utilitarian or prioritarian, applied to policy choice under risk in either an “ex post” or “ex ante” manner. We examine the conditions on individual utility and on the SWF under which these frameworks display sensitivity to wealth and to baseline risk. Moreover, we discuss whether these frameworks satisfy related properties that have received some attention in the literature, namely equal value of …

Inequality And Uncertainty: Theory And Legal Applications, Matthew D. Adler, Chris William Sanchirico

Faculty Scholarship

"Welfarism" is the principle that social policy should be based solely on individual well-being, with no reference to 'fairness" or "rights." The propriety of this approach has recently been the subject of extensive debate within legal scholarship. Rather than contributing (directly) to this debate, we identify and analyze a problem within welfarism that has received far too little attentioncall this the "ex ante/ex post" problem. The problem arises from the combination of uncertainty-an inevitable feature of real policy choice-and a social preference for equality. If the policymaker is not a utilitarian, but rather has a "social welfare function" that is …
