Abstract

I introduce the notion of circular domains and prove that on any circular domain there is no strategy-proof and nondictatorial social choice function. Moreover, I show that on any proper subset of a minimal circular domain, there exists a group strategy-proof and essential social choice function. These results together detect the minimal size of the domains over which the incompatibility arises with respect to pairs of democratic-incentive requirements (nondictatorial, strategy-proof) and (essential, group strategy-proof).
