Sequential Elimination vs. Instantaneous Voting
نویسندگان
چکیده
Voting procedures eliminating candidates sequentially and one-at-a-time based on repeated ballots are superior to well-known single-round voting rules: if voters are strategic the former will induce the Condorcet winner in unique equilibrium, whereas the latter may fail to select it. In addition, when there is no Condorcet winner the outcome of sequential elimination voting always belongs to the ‘top cycle’. The proposed sequential family is quite large, including an appropriate adaptation of all single-round voting procedures. The importance of one-by-one elimination and repeated ballots for Condorcet consistency is further emphasized by its failure for voting rules such as plurality runoff rule, exhaustive ballot method, and instant runoff voting. JEL Classification Numbers: P16, D71, C72.

Multi-stage voting, sequential elimination and Condorcet consistency
A class of voting procedures based on repeated ballots and elimination of one candidate in each round is shown to always induce an outcome in the top cycle and is thus Condorcet consistent, when voters behave strategically. This is an important class as it covers multi-stage, sequential elimination extensions of all standard one-shot voting rules (with the exception of negative voting), the sam...

Introduction: This study presents a computerized analyzing method for detection of instantaneous changes of far and near walls of the common carotid artery in sequential ultrasound images by applying the maximum gradient algorithm. Maximum gradient was modified and some characteristics were added from the dynamic programming algorithm for our applications. Methods: The algorithm was evaluat...
متن کاملVoting by sequential elimination with few voters
We define a new class of low-communication voting rules, tailored for contexts with few voters and possibly many candidates. These rules are defined by a predefined sequence of voters: at each stage, the designated voter eliminates a candidate, and the last remaining candidate wins. We study deterministic and randomized versions of these rules. We first investigate their axiomatic properties. T...
متن کاملE¢ ciency, Equity, and Timing of Voting Mechanisms1
We compare the behavior of voters under simultaneous and sequential voting rules when voting is costly and information is incomplete. In many political institutions, ranging from small committees to mass elections, voting is sequential, which allows some voters to know the choices of earlier voters. For a stylized model, we generate a variety of predictions about the relative e¢ ciency and part...
