Voting procedures focus on the aggregation of individuals' preferences to produce collective decisions. In practice, a voting procedure is characterized by ballot responses and the way ballots are tallied to determine winners. Voters are assumed to have clear preferences over candidates and...

Within the framework of the axiomatic approach three types of voting schemes are investigated according to the form in which the individual opinions about the alternatives are defined, as well as to the form of desired social decision. These types of rules are Social Decision Rules, Functional...

This chapter surveys the literature on strategy proofness from a historical perspective. While I discuss the connections with other works on incentives in mechanism design, the main emphasis is on social choice models.

The Qualified Majority Voting (QMV) used by the Council of the European Union developed to a high degree of complexity from one modifying treaty to another, until the latest definition stipulated in the Treaty of Lisbon. This paper analyses this EU intra-institutional voting method using a...

We estimate a model of strategic voting and quantify the impact it has on election outcomes. Because the model exhibits multiplicity of outcomes, we adopt a set estimator. Using Japanese general-election data, we find a large fraction [63.4%, 84.9%] of strategic voters, only a small fraction...

We introduce 'Balanced Voting', a new voting scheme that is particularly suitable for making fundamental societal decisions. Such decisions typically involve subgroups that are strongly in favor of, or against, a new fundamental direction, and others that care much less. In a two-stage...

Median voter theorem has been used in many economic environments including law enforcement. Assumptions of the median voter theorem, however, are generally violated in lawenforcement models. Moreover, it is impossible to have agents with "opposite equilibrium preferences" over enforcement levels...

Does redistribution in democracies cater to the will of the majority? We propose a direct empirical strategy based on survey data that needs not assume that voters are guided by pecuniary motives alone. We find that most democracies implement the median voter's preferred amount of redistribution...

This paper studies a collective decision problem in which a group of individuals with interdependent preferences vote whether or not to implement a public project of unknown value. A utilitarian social planner aggregates these votes according to a majority rule; but, unlike what is commonly...
