We analyze the aggregation problem without the assumption that individuals and society have fully determined and … utilities, where it basically reduces to utilitarianism. In particular, aggregation rules may differ by the relationship between … individual and social indeterminacy. We characterize several subclasses of neutral aggregation rules and show that utilitarian …
