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...

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...

Constitutional structures shape politicians' behaviour and hence policy outcomes through the di fferent incentive schemes at work. In this paper we analyse these mechanisms in parliamentary and presidential systems. Such a comparison is carried over by analysing how the two systems are able to...

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...

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 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. Minority candidate can illicitly...

In this paper we propose a model with uncertainty in which strategic voters vote, under poportional rule, for a Parliament and parties bargain to form a government. We prove that only consensus government form and only extreme parties take votes

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...

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...
