Approval Ballot
An approval ballot, also called an unordered ballot, is a ballot in which a voter may vote for any number of candidates simultaneously, rather than for just one candidate. Candidates that are selected in a voter's ballot are said to be ''approved'' by the voter; the other candidates are said to be ''disapproved'' or ''rejected''. Approval ballots do not let the voters specify a preference-order among the candidates they approve; hence the name ''unordered''. This is in contrast to ranked ballots, which are ordered. There are several electoral systems that use approval balloting; they differ in the way in which the election outcome is determined: * In approval voting, there is a single winner, and he/she is the candidate with the largest number of votes. * In multiple non-transferable vote (also called block voting) there is a fixed number (say ''k'') of winners, and they are the ''k'' candidates with the largest number of votes. * In other multiwinner approval voting systems, there i ...

Ballot
A ballot is a device used to cast votes in an election and may be found as a piece of paper or a small ball used in secret voting. It was originally a small ball (see blackballing) used to record decisions made by voters in Italy around the 16th century. Each voter uses one ballot, and ballots are not shared. In the simplest elections, a ballot may be a simple scrap of paper on which each voter writes in the name of a candidate, but governmental elections use pre-printed ballots to protect the secrecy of the votes. The voter casts their ballot in a box at a polling station. In British English, this is usually called a "ballot paper". The word ''ballot'' is used for an election process within an organization (such as a trade union "holding a ballot" of its members). Etymology The word ballot comes from Italian ''ballotta'', meaning a "small ball used in voting" or a "secret vote taken by ballots" in Venice, Italy. History In ancient Greece, citizens used pieces of broken pot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ranked Ballots
The term ranked voting (also known as preferential voting or ranked choice voting) refers to any voting system in which voters rank their candidates (or options) in a sequence of first or second (or third, etc.) on their respective ballots. Ranked voting systems differ on the basis of how the ballots are marked, how the preferences are tabulated and counted, how many seats are filled, and whether voters are allowed to rank candidates equally. An electoral system that uses ranked voting uses one of the many available counting methods to select the winning candidate or candidates. There is also variation among ranked voting electoral systems in that in some ranked voting systems, officials require voters to rank a set number of candidates, sometimes all of them; in others, citizens may rank as many candidates as they see fit. Election of single members using ranked votes is often instant-runoff voting. Election of multiple members using ranked votes is usually single transferab ...

Electoral System
An electoral system or voting system is a set of rules that determine how elections and Referendum, referendums are conducted and how their results are determined. Electoral systems are used in politics to elect governments, while non-political elections may take place in business, Nonprofit organization, non-profit organisations and informal organisations. These rules govern all aspects of the voting process: when elections occur, suffrage, who is allowed to vote, who can stand as a candidate, voting method, how ballots are marked and cast, how the ballots are counted, how votes translate into the election outcome, limits on campaign finance, campaign spending, and other factors that can affect the result. Political electoral systems are defined by constitutions and electoral laws, are typically conducted by election commissions, and can use multiple types of elections for different offices. Some electoral systems elect a single winner to a unique position, such as prime ministe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Approval Voting
Approval voting is an electoral system in which voters can select many candidates instead of selecting only one candidate. Description Approval voting ballots show a list of the options of candidates running. Approval voting lets each voter indicate support for one or more candidates. Final tallies show how many votes each candidate received, and the winner is the candidate with the most support. Effect on elections Approval voting advocates Steven Brams and Dudley R. Herschbach predict that approval voting should increase voter participation, prevent minor-party candidates from being spoilers, and reduce negative campaigning. FairVote published a position paper arguing that approval voting has three flaws that undercut it as a method of voting and political vehicle (the group instead advocates for Instant-runoff voting). They argue that it can result in the defeat of a candidate who would win an absolute majority in a plurality election, can allow a candidate to win who ...

Multiple Non-transferable Vote
The multiple non-transferable vote (MNTV) is a group of voting system, in which voters elect several representatives at once, with each voter having more than one vote. MNTV uses multi-member electoral districts or only one district, which contains all voters, which is used to provide at-large representation. MNTV systems are not designed towards obtaining proportional representation; instead the usual result is that where the candidates divide into definitive parties (especially for example where those parties have party lines which are whipped) the most popular party in the district sees its full slate of candidates elected, resulting in a landslide. The exceptions to this are Limited Voting or Cumulative Voting, both of which are brought in on purpose to produce diverse representation—minority representation as well as representation of the largest group. But other systems have proven themselves more dependable at producing Proportional Representation than those two - pa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Multiwinner Approval Voting
Multiwinner approval voting, also called approval-based committee voting, is a multi-winner electoral system that uses approval ballots. Each voter may select ("approve") any number of candidates, and multiple candidates are elected. The number of elected candidates is usually fixed in advance. For example, it can be the number of seats in a country's parliament, or the required number of members in a committee. Multiwinner approval voting is an adaptation of approval voting to multiwinner elections. In a single-winner approval voting system, it is easy to determine the winner: it is the candidate approved by the largest number of voters. In multiwinner approval voting, there are many different ways to decide which candidates will be elected. Majoritarian approval voting Versions Block approval voting (unlimited voting) The straightforward extension of approval balloting to multi-winner elections is called block approval voting and is a type of multiple non-transferable ...

Justified Representation
Justified representation (JR) is a criterion for evaluating the fairness of electoral systems in multiwinner voting, particularly in multiwinner approval voting. It can be seen as an adaptation of the proportional representation criterion to approval voting. Definitions One definition for "proportional representation" is that the candidates are partitioned into disjoint parties, and each voter approves all candidates in a single party. For example, suppose we need to elect a committee of size 10. Suppose that exactly 50% of the voters approve all candidates in party A, exactly 30% approve all candidates in party B, and exactly 20% approve all candidates in party C. Then, proportional representation requires that the committee contains exactly 5 candidates from party A, exactly 3 candidates from party B, and exactly 2 candidates from party C. If the fractions are not exact, then some rounding method should be used, and this can be done by various Apportionment (politics), appor ...

Dichotomous Preferences
In economics, dichotomous preferences (DP) are preference relations that divide the set of alternatives to two subsets: "Good" versus "Bad". From ordinal utility perspective, DP means that for every two alternatives X,Y: : X \preceq Y \iff X \in Bad \text Y \in Good : X \prec Y \iff X \in Bad \text Y \in Good From cardinal utility perspective, DP means that for each agent, there are two utility levels: low and high, and for every alternative X: : u(X) = u_ \iff X\in Bad : u(X) = u_ \iff X\in Good A common way to let people express dichotomous preferences is using approval ballots, in which each voter can either "approve" or "reject" each alternative. In fair item assignment In the context of fair item assignment, DP can be represented by a mathematical logic formula: for every agent, there is a formula that describes his desired bundles. An agent is satisfied if-and-only-if he receives a bundle that satisfies the formula. A special case of DP is single-mindedness. A sin ...
