This paper provides a model of indirect elections where voters having weak orders as preferences over finitely many alternatives are distributed across a given set of districts. In each district preferences are aggregated into a district preference, and a voting rule selects one or several...

We establish a new sufficient condition for avoiding a generalized Anscombe’s paradox. In a situation where votes describe positions regarding finitely many yes-or-no issues, the Anscombe’s α-paradox holds if more than α% of the voters disagree on a majority of issues with the outcome of...

We introduce a new consistency condition for neutral social welfare functions, called hyperstability. A social welfare function a selects a complete weak order from a profile PN of linear orders over any finite set of alternatives, given N individuals. Each linear order P in PN generates a...

We define generalized (preference) domains <InlineEquation ID="IEq1"> <EquationSource Format="TEX">$\mathcal{D}$</EquationSource> </InlineEquation> as subsets of the hypercube {−1,1}<Superscript> D </Superscript>, where each of the D coordinates relates to a yes-no issue. Given a finite set of n individuals, a profile assigns each individual to an element of <InlineEquation ID="IEq2"> <EquationSource Format="TEX">$\mathcal{D}$</EquationSource> </InlineEquation>. We prove that, for any domain <InlineEquation ID="IEq3"> <EquationSource...</equationsource></inlineequation></equationsource></inlineequation></superscript></equationsource></inlineequation>

The purpose of the model is to analyse the genesis and evolution of consumption oriented chat rooms in the Web space. We study an endogeneous consumption dynamics in which individuals make their buying decisions on the basis of a threefold information: their own consumption past experience...
