We show that manipulation is not desirable for the society, and the candidates’ incentives for manipulating can be mitigated by appropriately sequencing the order of manipulations. We present some results of a manipulation game which may rather unexpected under the assumption that the candidates have prior beliefs about each others’ manipulations. Finally we determine the set of manipulations which can be prevented by informed voters for a given composition of society.vi, 76 leavesEnglishinfo:eu-repo/semantics/openAccessVotingManipulationSocial WelfareVoter TurnoutTrust RatioJF1001 .S49 2006Elections.Manipulation via information in large electionsThesisBILKUTUPB096136
