Instant Runoff Voting and the Reinforcement Paradox
David McCune, Jennifer Wilson
We analyze the susceptibility of instant runoff voting (IRV) to a lesser-studied paradox known as a \emph{reinforcement paradox}, which occurs when candidate wins under IRV in…
Multiwinner Elections and the Spoiler Effect
David McCune, Jennifer Wilson
In the popular debate over the use of ranked-choice voting, it is often claimed that the method of single transferable vote (STV) is immune or mostly immune to the so-called ``spoi…
The Negative Participation Paradox in Three-Candidate Instant Runoff Elections
David McCune, Jennifer Wilson
In this paper, we provide theoretical and empirical estimates for the likelihood of a negative participation paradox under instant runoff voting in three-candidate elections. We de…
Proportional Consistency of Apportionment Methods
Michael A. Jones, David McCune, Jennifer M. Wilson
We analyze a little-known property of apportionment methods that captures how allocations scale with the size of the house: specifically, if, for a fixed population distribution, t…
A Comparison of Sequential Ranked-Choice Voting and Single Transferable Vote
David McCune, Erin Martin, Grant Latina +1
The methods of single transferable vote (STV) and sequential ranked-choice voting (RCV) are different methods for electing a set of winners in multiwinner elections. STV is a class…
An Empirical Analysis of the Effect of Ballot Truncation on Ranked-Choice Electoral Outcomes
Mallory Dickerson, Erin Martin, David McCune
In ranked-choice elections voters cast preference ballots which provide a voter's ranking of the candidates. The method of ranked-choice voting (RCV) chooses a winner by using vote…
Paradoxical Oddities in Two Multiwinner Elections from Scotland
Adam Graham-Squire, David McCune
Ranked-choice voting anomalies such as monotonicity paradoxes have been extensively studied through creating hypothetical examples and generating elections under various models of…
Monotonicity Anomalies in Scottish Local Government Elections
David McCune, Adam Graham-Squire
Single Transferable Vote (STV) is a voting method used to elect multiple candidates in ranked-choice elections. One weakness of STV is that it fails multiple fairness criteria rela…
Ranked Choice Bedlam in a 2022 Oakland School Director Election
David McCune
The November 2022 ranked choice election for District 4 School Director in Oakland, CA, was very interesting from the perspective of social choice theory. The election did not cont…
An Examination of Ranked Choice Voting in the United States, 2004-2022
Adam Graham-Squire, David McCune
From the perspective of social choice theory, ranked-choice voting (RCV) is known to have many flaws. RCV can fail to elect a Condorcet winner and is susceptible to monotonicity pa…
A Mathematical Analysis of the 2022 Alaska Special Election for US House
Adam Graham-Squire, David McCune
The August 2022 Alaska Special Election for US House contained many interesting features from the perspective of social choice theory. This election used instant runoff voting (oft…
The Curious Case of the 2021 Minneapolis Ward 2 City Council Election
David McCune, Lori McCune
In this article we explain why the November 2021 election for the Ward 2 city council seat in Minneapolis, MN, may be the mathematically most interesting ranked choice election in…
Semigroups Arising From Asynchronous Automata
David McCune
We introduce a new class of semigroups arising from a restricted class of asynchronous automata. We call these semigroups "expanding automaton semigroups." We show that the class o…
