Characterization of domains admitting strategy-proof and non-dictatorial social choice functions: A reappraisal (Discussion paper no. 2007-1, CEPET - Central European Program in Economic Theory, Institute of Public Economics, Graz University)
We show, with an example, that the theorem on the characterization of domains admitting strategy-proof and non-dictatorial social
choice functions by Kalai and Muller (1977) does not hold when the
set of alternatives is infinite. Then, we introduce a class of social
choice functions for which it is possible to restore the validity of the
theorem also in this case.
