Election theorists have postulated that elections might be drawn from various stochastic preference models, including the IC and IAC conditions, but these models induce empirically contradicted predictions. We use two distinct data sets, FairVote and German Politbarometer survey. Based on the data information, we suggest approaches that differ from those probabilistic models to better approximate the actual data in Chapter 3 and 4. Chapter 5 applies the spatial model for four-candidate in a three-dimensional setting. We also offer a significant gap between the actual and simulated data under the IAC conditions by comparing their statistical characteristics.ETDenCreative Commons Attribution-NonCommercial 4.0 InternationalCondorcet paradoxVoting paradoxSocial choiceAlternative voteCollective decision makingInstant-Runoff VotingElectionAgent-based modelingDissertation
