Abstract

The article presents an important application of spatial generalization of Shapley value for simple games. Proposition presented by Shapley and Owen enables very interesting empirical interpretations. It has also strong contribution in the research of spatial voting models’ properties when there is no stable solution. This theorem enables us to fi nd the least unstable solution and therefore this is the valuable answer to the problem presented in the McKelvey’s theorem. The article presents the main postulates of the spatial voting theory, a geometric insight on which the general proof of Shapley-Owen theorem is based and empirical illustration of the presented concepts.

Abstract

The paper presents the concept of reconstructing the ideological space in parliament on the basis of the MPs' voting. Problems arising during the study of ideology in political science were discussed. A concept of "ideology in action" was presented on the basis of the texts of the classics of modern theories of democracy. The concept was presented as contrasted with a traditional concept of ideology as the project of reality. The theoretical andempirical arguments justifying ex-post modeling of the ideological space were presented. The properties and interpretation of the ideological distances defined in accordance with the proposed approach were described. The results of the ideological space in the Sejm of sixth and seventh term were presented. Further analytical capabilities offered by the proposed approach were discussed as well.
