Spatial Model Of Voting
In social choice theory, the spatial model of voting is used to simulate the behavior of voters in an election, either to explain voter behavior, or to estimate the likelihood of desirable or undesirable outcomes under different voting systems. This model positions voters and candidates in a one- or multi-dimensional space, where each dimension represents an attribute of the candidate that voters care about. Voters are then modeled as having an ''ideal point'' in this space, and voting for the nearest candidates to that point. (As this is a mathematical model that can apply to any form of election, including non-governmental elections, each dimension can represent any attribute of the candidates, such as a single political issue sub-component of an issue, or non-political properties of the candidates, such as perceived corruption, health, etc.) A political spectrum or compass can therefore be thought of as either an attribute space itself, or as a projection of a higher-dimension ...

Social Choice Theory
Social choice theory or social choice is a theoretical framework for analysis of combining individual opinions, preferences, interests, or welfares to reach a ''collective decision'' or ''social welfare'' in some sense.Amartya Sen (2008). "Social Choice,". ''The New Palgrave Dictionary of Economics'', 2nd EditionAbstract & TOC./ref> Whereas choice theory is concerned with individuals making choices based on their preferences, social choice theory is concerned with how to translate the preferences of individuals into the preferences of a group. A non-theoretical example of a collective decision is enacting a law or set of laws under a constitution. Another example is voting, where individual preferences over candidates are collected to elect a person that best represents the group's preferences. Social choice blends elements of welfare economics and public choice theory. It is methodologically individualistic, in that it aggregates preferences and behaviors of individual member ...

Thermometer Scale
A feeling thermometer, also known as a thermometer scale, is a type of visual analog scale that allows respondents to rank their views of a given subject on a scale from "cold" (indicating disapproval) to "hot" (indicating approval), analogous to the temperature scale of a real thermometer. It is often used in survey and political science research to measure how positively individuals feel about a given group, individual, issue, or organisation, as well as in quality of life research to measure individuals' subjective health status. It typically uses a rating scale with options ranging from a minimum of 0 to a maximum of 100. Questions using the feeling thermometer have been included in every year of the American National Election Studies since 1968. Since its inclusion in a national forum, the tool has developed and become popular in both the political sphere and for medical and psychological research purposes. As it is a relatively new method of research and is still being studi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Location Model
In economics, a location model or spatial model refers to any monopolistic competition model that demonstrates consumer preference for particular brands of goods and their locations. Examples of location models include Hotelling’s Location Model, Salop’s Circle Model, and hybrid variations. Traditional vs. location models In traditional economic models, consumers display preference given the constraints of a product characteristic space. Consumers perceive certain brands with common characteristics to be close substitutes, and differentiate these products from their unique characteristics. For example, there are many brands of chocolate with nuts and others without them. Hence, the chocolate with nuts is a constraint of its product characteristic space. On the other hand, consumers in location models display preference for both the utility gained from a particular brand’s characteristics as well as its geographic location; these two factors form an enhanced “product ...

Issue Voting
The term issue voting describes when voters cast their vote in elections based on political issues. In the context of an election, issues include "any questions of public policy which have been or are a matter of controversy and are sources of disagreement between political parties.” According to the theory of issue voting, voters compare the candidates' respective principles against their own in order to decide for whom to vote. Causes A voter does not need to have an in-depth understanding of every issue and knowledge of how a candidate stands on every issue, but rather a sense of which candidate they agree with the most. Voters use many different tactics to rationalize their view on a particular issue. Some people look at what has happened in the past and predict how they think a particular issue will affect them in the future. Issue voting is often contrasted with party voting. A 2010 University of California, Davis study found that voters switch between issue voting and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Median Voter Theorem
The median voter theorem is a proposition relating to ranked preference voting put forward by Duncan Black in 1948.Duncan Black, "On the Rationale of Group Decision-making" (1948). It states that if voters and policies are distributed along a one-dimensional spectrum, with voters ranking alternatives in order of proximity, then any voting method which satisfies the Condorcet criterion will elect the candidate closest to the median voter. In particular, a majority vote between two options will do so. The theorem is associated with public choice economics and statistical political science. Partha Dasgupta and Eric Maskin have argued that it provides a powerful justification for voting methods based on the Condorcet criterion. Plott's majority rule equilibrium theorem extends this to two dimensions. A loosely related assertion had been made earlier (in 1929) by Harold Hotelling. It is not a true theorem and is more properly known as the median voter theory or median voter model. It ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Duncan Black
Duncan Black, FBA (23 May 1908 – 14 January 1991) was a Scottish economist who laid the foundations of social choice theory. In particular he was responsible for unearthing the work of many early political scientists, including Charles Lutwidge Dodgson, and was responsible for the Black electoral system, a Condorcet method whereby, in the absence of a Condorcet winner (e.g. due to a cycle), the Borda winner is chosen. Biography Black was born in Motherwell, Scotland, an industrial town south east of Glasgow, to a working-class family. He graduated from the Dalziel High School in Motherwell and then studied mathematics and physics at the University of Glasgow. He then enrolled for a degree in economics and politics which he finished with first class honours in 1932. He started teaching at the newly formed Dundee School of Economics (later part of the University of Dundee). There Black was influenced by his colleague Ronald Coase, originator of the Theory of the Firm. He ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hotelling's Law
Hotelling's law is an observation in economics that in many markets it is rational for producers to make their products as similar as possible. This is also referred to as the principle of minimum differentiation as well as Hotelling's linear city model. The observation was made by Harold Hotelling (1895–1973) in the article "Stability in Competition" in ''Economic Journal'' in 1929. The opposing phenomenon is product differentiation, which is usually considered to be a business advantage if executed properly. Example Suppose there are two competing shops located along the length of a street running north and south, with customers spread equally along the street. Both shop owners want their shops to be where they will get most market share of customers. If both shops sell the same range of goods at the same prices then the locations of the shops are themselves the 'products'. Each customer will always choose the nearer shop as it is disadvantageous to travel to the fa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
2017 French Presidential Election
The 2017 French presidential election was held on 23 April and 7 May 2017. As no candidate won a majority in the first round, a runoff was held between the top two candidates, Emmanuel Macron of En Marche! (EM) and Marine Le Pen of the National Front (FN), which Macron won with a difference of more than 30% of the vote. The presidential election was followed by a legislative election to elect members of the National Assembly on 11 and 18 June. Incumbent president François Hollande of the Socialist Party (PS) was eligible to run for a second term, but declared on 1 December 2016 that he would not seek reelection in light of low approval ratings, making him the first incumbent head of state of the Fifth Republic not to seek reelection. François Fillon of The Republicans (LR)—after winning the party's first open primary—and Le Pen of the National Front led first-round opinion polls in November 2016 and mid-January 2017. Polls tightened considerably by late January; after ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cardinal Voting
Cardinal voting refers to any electoral system which allows the voter to give each candidate an independent evaluation, typically a rating or grade. These are also referred to as "rated" (ratings ballot), "evaluative", "graded", or "absolute" voting systems. ''Cardinal'' methods (based on cardinal utility) and '' ordinal methods'' (based on '' ordinal utility'') are two main categories of modern voting systems, along with plurality voting. Variants There are several voting systems that allow independent ratings of each candidate. For example: * Approval voting (AV) is the simplest possible method, which allows only the two grades (0, 1): "approved" or "unapproved". * Evaluative voting (EV) or combined approval voting (CAV) uses 3 grades (−1, 0, +1): "against", "abstain", or "for". * Score voting or range voting, in which ratings are numerical and the candidate with the highest ''average'' (or total) rating wins. ** Score voting uses a discrete integer scale, typic ...

Election
An election is a formal group decision-making process by which a population chooses an individual or multiple individuals to hold public office. Elections have been the usual mechanism by which modern representative democracy has operated since the 17th century. Elections may fill offices in the legislature, sometimes in the executive and judiciary, and for regional and local government. This process is also used in many other private and business organisations, from clubs to voluntary associations and corporations. The global use of elections as a tool for selecting representatives in modern representative democracies is in contrast with the practice in the democratic archetype, ancient Athens, where the elections were considered an oligarchic institution and most political offices were filled using sortition, also known as allotment, by which officeholders were chosen by lot. Electoral reform describes the process of introducing fair electoral systems wher ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electoral Reform Society
The Electoral Reform Society (ERS) is an independent campaigning organisation based in the United Kingdom which promotes electoral reform. It seeks to replace first-past-the-post voting with proportional representation, advocating the single transferable vote. It is the world's oldest operating organisation concerned with political and electoral reform. Overview The Electoral Reform Society seeks a "representative democracy fit for the 21st century." The Society advocates the replacement of the first-past-the-post and plurality-at-large voting systems with a proportional voting system, the single transferable vote. First-past-the-post is currently used for elections to the House of Commons and for most local elections in England and Wales, while plurality-at-large is used in multi-member council wards in England and Wales, and was historically used in the multi-member parliamentary constituencies before their abolition. It also campaigns for improvements to public elections ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
