Forthcoming (and open-access) in the Journal of Political Philosophy from Walter Bossert (University of Montreal), Susumu Cato (University of Tokyo), and Kohei Kamaga (Sophia University), "Critical-Level Sufficientarianism" supplements the utilitarian basis of normative policy-oriented economics with the requirement that no one ends up with too little:
In this article, we employ an axiological approach to identify a class of sufficientarian principles. Our starting point is the notion of absolute priority, a requirement that we consider to be at the very core of sufficientarian ideas. Absolute priority postulates that attention is to be focused on those whose well-being is below the threshold, and the utilities of those above the threshold only matter as a tie-breaker if the criterion to be applied below the threshold fails to be decisive. The feature that is novel to our approach is that we combine this fundamental sufficientarian principle with axioms that have a distinctly utilitarian flavor. This allows us to develop a sufficientarian theory that is based on utilitarian principles. Our most important observation is that our theory, which we refer to as critical-level sufficientarianism, necessarily follows as a consequence of adding the absolute-priority requirement to utilitarian axioms.
