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 in a strict linear order. A social choice function is a rule which, to every finite committee of voters with specified preference orders, assigns a nonempty subset of A, interpreted as the set of “winners”. A social choice function is consistent if, whenever two disjoint committees meeting separately… 
Scoring rules and social choice properties: some characterizations
In many voting systems, voters’ preferences on a set of candidates are represented by linear orderings. In this context, scoring rules are well-known procedures to aggregate the preferences of the
Variable-population voting rules
Scoring Rules and Consensus
TLDR
This paper considers that voters rank order a set of alternatives and a scoring rule is used for obtaining a setOf winning alternatives, which is not previously fixed, and analyzes how to select one of them in such a way that the collective utility is maximized.
On the role of distances in defining voting rules
TLDR
It is demonstrated that if a rule is rationalized via a distance from this class, many important properties of this rule can be easily expressed in terms of the underlying distance, which enables a new characterization of scoring rules and to establish a connection with the MLE framework.
On the likelihood of Condorcet's profiles
Abstract. Consider a group of individuals who have to collectively choose an outcome from a finite set of feasible alternatives. A scoring or positional rule is an aggregation procedure where each
Separable Voting Rules and the Strong Referendum Paradox
This paper provides a model of indirect elections where voters having weak orders as preferences over finitely many alternatives are distributed across a given set of districts. In each district
Stable Rules for Electing Committees and Divergence on Outcomes
TLDR
This paper describes all the voting situations under which a committee selected by a stable rule may differ from the committee made by the best candidates of the corresponding classical rule from which this stable rule is adapted and evaluates the likelihood of this event using the impartial anonymous culture assumption.

TLDR
This talk argues that the language of committee scoring rules is sufficiently rich to capture many interesting interpretations of this phrase, and shows that exact meaning of the phrase “most satisfying” strongly depends on the context.
The Copeland Decision Mechanism
The so called Copeland preference rule is characterized. A preference rule is a function which assigns to every profile or combination of individual preferences over a fixed finite population N a
