Electoral system: Difference between revisions

Voting systems can be abstracted as mathematical functions that select between choices based on the [[utility]] of each option for each voter. This greatly resembles a [[social welfare function]] as studied in welfare economics and many of the same considerations can be studied. For aspects such as simplicity, dispute, and fraud, the practical implementation is far more important than the abstract function. However, the choice of abstract function puts some constraints on the implementation. For instance, certain voting systems such as First Past the Post, [[Schulze method|Schulze]], or Borda Count can be tallied in one distributed step, others such as IRV require centralization, and others such as multi-round runoff require multiple polling rounds.
