Why majoritarian election methods should be Condorcet-efficient

  title={Why majoritarian election methods should be Condorcet-efficient},
  author={James Green-Armytage}
This paper introduces a new Condorcet-efficient voting method that uses ordinal information to determine the direction of pairwise defeats, and cardinal information to determine the strength of pairwise defeats. In this paper, I attempt to explain why Condorcet-efficient methods are desirable, identify the areas in which heretofore-proposed Condorcet-efficient methods could be improved, define the cardinal-weighted pairwise method, provide an example computation, discuss the rationale behind… 


Better Voting Methods Through Technology: The Refinement-Manageability Trade-Off in the Single Transferable Vote
The Single Transferable Vote (STV) is an attractive way of achieving representation that is proportional in terms of whatever characteristics of candidates voters value. Increasingly sophisticated
A New Monotonic and Clone-Independent Single-Winner Election Method
A more detailed motivation and explanation of the method is overdue because this method immediately attracted a lot of attention and very many enthusiastic supporters.
Manipulation of Voting Schemes: A General Result
It has been conjectured that no system of voting can preclude strategic voting-the securing by a voter of an outcome he prefers through misrepresentation of his preferences. In this paper, for all
Social Choice Scoring Functions
Let a committee of voters be considering a finite set $A = \{ {a_1 ,a_2 , \cdots ,a_m } \}$ of alternatives for election. Each voter is assumed to rank the alternatives according to his preferences
Independence of clones as a criterion for voting rules
Abstract“Independence of clones” is a generalization of the condition of not being subject to the perverse consequences of vote splitting that arise under plurality voting. A new voting rule that is
Monotonicity of Single-seat Preferential Election Rules
Condorcet's principle implies the no show paradox
The logic of collective choice
A modal logic that extends propositional logic with a binary modality so that a formula can express not only properties of alternatives but also priorities of individuals over the properties and develops a model checking algorithm to automatically generate individual and collective choices in the logic.
The Single Transferable Vote
The single transferable vote (STV) is a family of vote-counting procedures that use voters' rankings of candidates as input and achieve proportional representation. This paper compares STV with other
