Arrow's Impossibility Theorem

Friday, October 2, 2015, 5:00pm
Ungar Building Room 402


In this talk, we will offer a proof of Arrow's impossibility theorem, which states that there is no rank order voting system that satisfies certain "fairness" criteria. While Arrow's theorem is popularly interpreted as "there is no perfect voting system," we will also address the limitations of this interpretation of the theorem. We will also see how various common voting systems violate Arrow's theorem.
