Abstract: | For ? an anonymous exactly strongly consistent social choice function (ESC SCF) and x an alternative, define to be the size of a minimal blocking coalition for x. By studying the correspondence between ? and , we establish the existence, uniqueness and monotonicity of ESC SCF's. We also prove the following conjecture of B. Peleg: A non–constant anonymous ESC SCF depends on the knowledge of every player's full preference profile. |
