I am wondering if anyone has come across peer-reviewed studies that explore how election winners can vary depending on which voting system is used. Specifically, I am looking for experiments, not hypothetical scenarios. For example, we (at PolicyInteractive) invited MTurkers to each complete four presidential primary mock ballots within the systems of plurality, approval, range, and instant-runoff voting. We then compared who the resulting winners would be within each of those systems. I am wondering if anyone else has done something like that in the year or so since I last checked with you voting system authorities.
BTW, I will be sharing the results of the above-mentioned study as soon as I finish the report, which should be in a week or two.
Thanks in advance!
