STRATEGY-PROOF ALLOTMENT RULES

We consider the problem of allotting shares of a task or good among ag ents with single peaked preferences over their own shares. Previous ch aracterizations have examined rules, such as the uniform rule, which s atisfy various symmetry requirements. We consider the case where agent s might begin with natural claims to minimal or maximal allotments, or might be treated with different priorities. We provide characterizati ons of the rules which are strategy-proof and efficient, but which may treat individuals asymmetrically. (C) 1997 Academic Press.
