Title : Re-examining the foundations of voting theory
Abstract : The theory of voting is built on the social choice theory. The latter, in turn, is based on a notion of voter as a utility maximizer. For reasons of incomparability of the utility values of different individuals the utilities are typically measured on an ordinal scale. We shall discuss the nature of some well-known results of the social choice theory and comment on the significance of them from the view-point of institution design. Particular emphasis is paid to the incompatibilities of various social choice desiderata. Given that all voting procedures are associated with some serious flaws, is it possible to design opinion aggregation systems in a context-regarding manner, i.e. taking into account the environment where the procedure is to be applied? This possibility invokes the notions of the difficulty of constructing examples, the frequency of criterion violations and the plausibility of the ordinal utility maximizing individual.
