TL;DR: In this article, a comparison between instant runoff and Coombs rule is made, and it is shown that Coombs is always as good as AV with respect to two of the four criteria.

TL;DR: The authors used the 1966 NBC survey of candidates for the House of Representatives and the SRC national election survey to examine the electoral impact of policy positions of candidates and found that the importance of candidates' policy positions is affirmed.
Abstract: Previous research and common wisdom holds that issues are not significant in congressional elections. This paper uses the 1966 NBC survey of candidates for the House of Representatives and the SRC national election survey to examine the electoral impact of policy positions of candidates. The importance of candidates' policy positions is affirmed. Party defection is higher when voters are closer to the opposition candidate. The importance of incumbency decreases and the importance of issues increases in elections with larger ideological distances between candidates. The effects of relative issue proximity to the candidates, although less than the influence of partisanship and incumbency, are nevertheless sufficiently large that constituency issue preferences should be a major consideration for rational vote-seeking candidates for Congress.

TL;DR: Using cross-sectional and longitudinal data, this article reported on the effects of changes in voting systems in Florida and Michigan and found that every change from old to new technology resulted in a decline in residual votes that was significantly greater than in areas that did not change voting equipment.
Abstract: Problems in the 2000 presidential election, especially in Florida, initiated a large-scale shift toward new voting technology. Using cross-sectional and longitudinal data, we report on the effects of changes in voting systems in Florida and Michigan. The variety of initial conditions and the numerous changes make these excellent case studies. We find that reforms succeeded in reducing the residual vote. Every change from old to new technology resulted in a decline in residual votes that was significantly greater than in areas that did not change voting equipment. The percentage of residual votes in the 2004 presidential race in localities that changed voting systems was well under 1 percent, representing a 90 percent reduction in error in Florida and a 35 percent reduction in Michigan. We run these analyses separately for undervotes and overvotes. Using ecological-inference techniques, we investigate the persistence of residual votes when technology changed and find very little persistence.

TL;DR: This work considers elections where the chair replaces either candidates or votes, with the goal of making a specific candidate win or lose (destructive control), and studies its computational complexity for several scoring rules, as well as for approval voting.
Abstract: We consider elections where the chair replaces either candidates or votes, with the goal of making a specific candidate win (constructive control) or lose (destructive control). We call this ``replacement control'' and study its computational complexity for several scoring rules (plurality, veto, Borda, k-approval), as well as for approval voting.
