Benefit-Cost Analysis And Distributional Weights: An Overview, Matthew D. Adler

Faculty Scholarship

Standard cost-benefit analysis (CBA) is insensitive to distributional concerns. A policy that improves the lives of the rich, and makes the poor yet worse off, will be approved by CBA as long as the policy’s aggregate monetized benefits are positive. Distributional weights offer an apparent solution to this troubling feature of the CBA methodology: adjust costs and benefits with weighting factors that are inversely proportional to the well-being levels (as determined by income and also perhaps non-income attributes such as health) of the affected individuals.

Indeed, an academic literature dating from the 1950s discusses how to specify distributional weights. And …

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. …

Well-Being, Inequality And Time: The Time-Slice Problem And Its Policy Implications, Matthew D. Adler

Faculty Scholarship

Should equality be viewed from a lifetime or "sublifetime" perspective? In measuring the inequality of income, for example, should we measure the inequality of lifetime income or of annual income? In characterizing a tax as "progressive" or "regressive," should we look to whether the annual tax burden increases with annual income, or instead to whether the lifetime tax burden increases with lifetime income? Should the overriding aim of anti-poverty programs be to reduce chronic poverty: being badly off for many years, because of low human capital or other long-run factors? Or is the moral claim of the impoverished person a …
