In a system of proportional representation, we study the interaction between a voter's turnout decision and her party choice, and how these relate to party polarization. Quantal response equilibria predict such interaction effects. In particular they predict (i) a Polarization Effect: reduced...

In this paper we analyze the consequences of the fairness recommendation of the Venice Commission in allocating voting districts among larger administrative regions. This recommendation requires the size of any constituency not to differ from the average constituency size by more than a fixed...

There are many situations in which different groups make collective decisions by committee voting, with each group represented by a single person. A natural question is what voting system such a committee should use. Concepts based on voting power provide guidelines for this choice. The two most...

We experimentally study the impact of adding an explicit nil vote option to the ballot in both compulsory and voluntary voting settings. We investigate this issue in an informational voting setting, in which some voters are uninformed and face the swing voter’s curse, implying that they can...

We propose a two-stage process called minority voting to allocate public projects in a polity. In the first period, a society decides by a simple majority decision whether to provide the public project. If the proposal in the first period is rejected, the process ends. Otherwise the process...

Increasing concern over corporate governance has led to calls for more shareholder in uence over corporate decisions, but allowing shareholders to vote on more issues, such as executive compensation, may not affect the quality of governance. We should expect instead that, under current rules,...

We extend approval voting so as to elect multiple candidates, who may be either individuals or members of a political party, in rough proportion to their approval in the electorate. We analyze two divisor methods of apportionment, first proposed by Jefferson and Webster, that iteratively...

In two laboratory surveys run in France during the 2014 European Elections, we asked the participants to provide their personal evaluations of the parties in terms of ideological proximity, and asked how they would vote under three proportional, closed-list voting rules: the (official)...
