We present a model where a society elects a parliament by voting for candidates belonging to two parties. The electoral rule determines the seats distribution between the two parties. We analyze two electoral rules, multidistrict majority and single-district proportional. In this framework, the...

We introduce a model with strategic voting in a parliamentary election with proportional representation and uncertainty about voters’ preferences. In any equilibrium of the model, most voters only vote for those parties whose positions are extreme. In the resulting parliament, a consensus...

We present a model where a society elects candidates belonging to two parties to a national parliament. The electoral rule determines the seats distribution between the two parties. The policy outcome is a function of the number of seats the two parties win in the election. We analyze two...

In this paper we propose a model in which there are ideological and strategic voters who vote under poportional rule. We prove that the behavior of ideological voters matters, in that it a¤ects the outcome. We also show how a subset of strategic voters changes his voting be- havior to balance...

Most of the voting models limit their analysis to the investigation of symmetric equilibria where "similar" voters make "similar" voting decisions. In this paper we examine the validity of this restriction in a model with costly plurality voting. We first show that in any pure strategy...

We prove that for generic plurality games with positive cost of voting, the number of Nash equilibria is finite. Furthermore all the equilibria are regular, hence stable sets as singletons.

We study the strategic behavior of voters in a model of proportional representation, in which the policy space is multidimensional. Our main finding is that in large electorate, under some assumptions on voters' preferences, voters essentially vote, in any equilibrium, only for the extreme parties.

Most of the voting models restrict themselves to the analysis of symmetric equilibria, i.e. equilibria in which "similar" voters make "similar" voting decisions. In this paper we investigate this assumption under costly plurality voting. In any pure strategy equilibrium, if two active voters...
