Maximal sensitivity under Strong Anonymity

This paper re-examines the incompatibility of Strong Pareto, as an axiom sensitivity, and Anonymity, impartiality, when comparing well-being profiles with a countably infinite number components. We ask how far Paretian principle can be extended without contradicting Anonymity. show that Anonymity combined four auxiliary axioms has two consequences: (i) There is sensitivity for increase in one component if only co-finite set other components are at least ɛ (>0) higher, (ii) adding people to population cannot have positive social value.
