The paradox of voting, also called Downs’ paradox, is that for a rational, self-interested voter, the costs of voting will normally exceed the expected benefits.
What does Condorcet winner mean?
The Condorcet winner is the person who would win a two-candidate election against each of the other candidates in a plurality vote.
What is a quadratic voting system?
Quadratic voting is a collective decision-making procedure which involves individuals allocating votes to express the degree of their preferences, rather than just the direction of their preferences. For example, a voter with a budget of 16 vote credits can apply 1 vote credit to each of the 16 issues.
What is pairwise voting?
For each possible pair of candidates, one pairwise count indicates how many voters prefer one of the paired candidates over the other candidate, and another pairwise count indicates how many voters have the opposite preference.
What is Anthony Downs rational choice theory?
In An Economic Theory of Democracy (1957), an early work in rational choice theory, Downs posited the paradox of voting, which claimed that significant elements of political life could not be explained in terms of voter self-interest.
What is the unanimity criterion?
Unanimity is agreement by all people in a given situation. Groups may consider unanimous decisions as a sign of e.g. social, political or procedural agreement, solidarity, and unity. Unanimity may be assumed explicitly after a unanimous vote or implicitly by a lack of objections.
What is the pairwise method?
Pairwise comparison generally is any process of comparing entities in pairs to judge which of each entity is preferred, or has a greater amount of some quantitative property, or whether or not the two entities are identical. In psychology literature, it is often referred to as paired comparison.
How does liquid democracy work?
The concept of liquid democracy describes a form of collective decision-making, which combines elements of direct democracy and representative democracy through the use of software. This allows voters to either vote on issues directly, or to delegate their voting power to a trusted person or party.
How does quadratic voting differ from the one person one vote majority voting system quizlet?
Quadratic voting is more likely (but not guaranteed) to result in economically efficient decisions than traditional one-person-one-vote (1p1v) majority voting systems. The part of game theory concerned with designing the rules of a game so as to maximize the likelihood of players reaching a socially optimal outcome.
Does Copeland’s method satisfy the Condorcet criterion?
The winner of the election under Copeland’s method is the candidate with the highest Copeland score; under Condorcet’s method this candidate wins only if he or she has the maximum possible score of n –1 where n is the number of candidates. Hence victory under this system amounts to satisfying the Condorcet criterion.
What is the IIA criterion?
Approval voting, range voting, and majority judgment satisfy the IIA criterion if it is assumed that voters rate candidates individually and independently of knowing the available alternatives in the election, using their own absolute scale.
What is the meaning of the Condorcet paradox?
Condorcet paradox. Jump to navigation Jump to search. The Condorcet paradox (also known as voting paradox or the paradox of voting) in social choice theory is a situation noted by the Marquis de Condorcet in the late 18th century, in which collective preferences can be cyclic, even if the preferences of individual voters are not cyclic.
What is the difference between Condorcet winner and definition?
Definition (Condorcet Winner) A Condorcet Winner is an alternative such that it gains a majority of votes when paired against each of the other alternatives. Definition (Condorcet Cycles) A Condorcet Cycle occurs when there is a violation of transitivity in the social preference ordering.
When does a Condorcet cycle occur what happens?
A Condorcet Cycle occurs when there is a violation of transitivity in the social preference ordering. With three alternatives x˜y ˜z ˜ . With four alternatives, you could have x˜y ˜z ˜q ˜ . If a Condorcet Cycle occurs, then there is no Condorcet Winner.
When does Condorcet always elect someone from the Smith set?
The Condorcet methods which always elect someone from the Smith set when there is no Condorcet winner are known as Smith-efficient. Note that using only rankings, there is no fair and deterministic resolution to the trivial example given earlier because each candidate is in an exactly symmetrical situation.
