Ideology and existence of 50% majority equilibria in Multidimensional spatial voting Models .

By Utku Unver and Hervé Crès


When aggregating individual preferences through the majority rule in an n-dimensional spatial voting model, the ‘worst-case’ scenario is a social choice configuration where no political equilibrium exists unless a super-majority rate as high as 1 — 1/(n+1) is adopted. In this paper we assume that a lower d-dimensional (dideology, mean voter theorem, spatial voting, super majority;
