We propose a theory-based experimental approach to compare the properties of approval voting (AV) with those of plurality. This comparison is motivated by the theoretical predictions that, in our aggregate uncertainty setup, AV should produce close to first-best outcomes, while plurality will...

Voting Theory generally concludes that -in first-past-the-post elections- 1) All votes should go to effective candidates (Duverger's Law); 2) Parties' platforms should converge (Median Voter Theorem). Observations, though, suggest that such predictions are not met in practice. We show that...

The majority runoff system is widely used around the world. Yet, our understanding of its properties and of voters' behavior is limited. In this paper, we fully characterize the set of strictly perfect voting equilibria in large three-candidate majority runoff elections. Considering all possible...
