Textbook Question
Chapter 15.2, Problem 20E
Irrelevant Alternatives in a Hare Method Election For the profile of voters in Exercise 13(a), Atlanta is selected by the Hare method in the preliminary non-binding decision.
(a) If the losing city, Chicago, withdraws after the nonbinding vote, which city wins the official vote? Use the voter profile in Exercise 13(a) with Chicago deleted for the official Hare method election.
(b) Does the Hare method violate the irrelevant alternatives criterion in this selection process?

An election is held among four candidates (A, B, C, and D). Using a voting
method we will call X, the winner of
the election is candidate A. However, candidate D has more than 50% of the
possible votes. Based on this
information, we can say that voting method X violates the
O Condorcet criterion
O monotonicity criterion.
O independence of irrelevant alternatives criterion.
O majority criterion.
Majority Criterion and Borda Method
A group of teachers are planning a conference. They are
members of Teachers for Tomorrow. They are coming from four
different states. The choices for holding the conference are:
• Atlanta (A),
• Perdido (P),
• Biloxi (B), and
Panama City (C).
Below are the results of the votes of all the teachers.
• Use the Borda method to determine the location the teachers chose.
• Determine if the Borda method violates the majority criterion.
