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...

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...

The effect of constitutional structures (such as the effect of a presidential vs. a parliamentary system) over policy outcomes has been widely studied in the economic literature. In this paper, we investigate whether stable parliamentary systems and unstable parliamentary systems behave...

In this paper we experimentally investigate the consequences of electoral fraud on voter turnout. The experiment is based on a strategic binary voting model where voters decide whether to cast a costly vote in favour of their preferred candidate or to abstain. The minority candidate can...

In this paper we refine the interpretation of the European two-dimensional political space and the investigation of its determinants compared to the approach commonly adopted in the spatial voting literature. Specifically, we take into account heterogeneity and cross-correlation among...

In this study, we implement a series of voting games in the laboratory to test whether a strategic voting behavior in a proportional system would arise and induce a two-party system. In each voting game, a finite number of subjects with single-peaked preferences, uniformly distributed on a...

This paper compares the ability to select the efficient policy of a parliamentary and a presidential constitutional setup. In order to do it we build a dynamic theoretical model with asymmetric information that succeeds in addressing both the politicians accountability and the competence...

Motivated by the need of understanding voting behavior under different electoral rules, Laslier et al. (2015) have conducted an online experiment in several European countries during the three weeks before the 2014 elections for the European Parliament, the EuroVotePlus experiment. This paper...
