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. …

Introduction: Toward Voice And Reflexivity, Olivier De Schutter, Katharina Pistor

Faculty Scholarship

In their introductory chapter, De Schutter and Pistor argue that in light of increasing absolute and relative scarcity of land and fresh water there is urgent need to improve the governance of these and other essential resources. Emphasizing “essentiality” shifts the debate from allocative efficiency to normative concerns of equity and dignity. Essential resources are indispensable for survival and/or for meaningful participation in a given community. Their allocation therefore cannot be left to the pricing mechanism alone. It requires new parameters for governance. The authors propose Voice and Reflexivity as the key parameters of such a regime. Voice is …

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 …
