In this paper we analyze a model of proportional representation that allows for both sincere and strategic voting. We prove that strategic voters vote only for the extreme parties in any equilibrium, if the electorate is large. Moreover, we show that there is an effect of sincere voters'...

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...

In this paper we analyze a model of proportional representation that allows for both sincere and strategic voting. We prove that strategic voters vote only for the extreme parties in any equilibrium,if the electorate is large.

Using the spatial theory of voting, this paper describes an institutional structure where there are two branches of the government: the executive, elected by plurality rule, and the legislative elected by proportional rule. The resulting policy outcome is described through a compromise between...

In this paper we show that in a simple spacital model where the government is chosen under strict proportional rule, if The outcome function is a linear combination of parties' positions, with coefficients equal to their share of seats, only a two-party voting equilibrium basically exists. The...

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.

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. Copyright Springer-Verlag Berlin/Heidelberg 2005

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...
