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...

We consider weak preference orderings over a set An of n alternatives. An individual preference is of refinement ≤ n if it first partitions An into subsets of ‘tied’ alternatives, and then ranks these subsets within a linear ordering. When n, preferences are coarse. It is shown that, if...

In a simple parametric general equilibrium model with S states of nature and K · S ¯rms |and thus potentially incomplete markets|, rates of super majority rule ½ 2 [0; 1] are computed which guarantee the existence of ½{majority stable production equilibria: within each ¯rm, no alternative...

When aggregating individual preferences through the majority rule in an n-dimensional spatial voting model, the worst-case scenario is a social choice conÞguration where no political equilibrium exists unless a super majority rate as high as 1−1/n is adopted. In this paper we assume that a...
