Restricted domains, Arrow social welfare functions and noncorruptible and nonmanipulable social choice correspondences: The case of private and public alternatives
An n-person social choice problem is considered in which the alternatives are \((n+1)\)-dimensional vectors, with the first component of such a vector being that part of the alternative affecting all the individuals together, while the \((i+1)\) component is the part of the alternative affecting individual i alone. Assuming that individuals are selfish, that they may be indifferent among alternatives and that each individual may choose his preferences out of a different set of permissible preferences, we prove that any set of restricted domains of preferences admits an n- person nondictorial Arrow-type social welfare function if and only if it admits an n-person nondictatorial, nonmanipulable and noncorruptible social choice correspondence.
