Manipulation of single-winner large elections by vote pairing

Abstract

Manipulation of indirect elections by vote pairing occurs when a group of voters in different electoral bodies secures a jointly preferred winner by performing pairwise exchanges of votes. We show that in elections involving a large enough number of districts, each with a large enough size, no reasonable constitution is immune to vote-pairing. (C) 2017 Elsevier B.V. All rights reserved.
