No player is a dictator, so well only consider two and three player coalitions. Underlining the critical players to make it easier to count: \(\left\{\underline{P}_{1}, \underline{P}_{2}\right\}\), \(\left\{\underline{P}_{1}, \underline{P}_{3}\right\}\). Show that Sequential Pairwise voting can violate the Majority criterion. Likewise, without player 2, the rest of the players weights add to 15, which doesnt reach quota, so player 2 also has veto power. In the election shown below under the Borda Count method, explain why voters in the second column might be inclined to vote insincerely. A player is said to be critical in a coalition if them leaving the coalition would change it from a winning coalition to a losing coalition. It is not necessary to put numbers in all of the boxes, but you should fill them in order, starting at the upper left and moving toward the lower right. Consider the weighted voting system [6: 4, 3, 2]. \(\mathrm{P}_{1}\) is pivotal 3 times, \(\mathrm{P}_{2}\) is pivotal 3 times, and \(\mathrm{P}_{3}\) is pivotal 0 times. Create a method for apportioning that incorporates this additional freedom, and describe why you feel it is the best approach. Players one and two can join together and pass any motion without player three, and player three doesnt have enough weight to join with either player one or player two to pass a motion. Either arrow down to the number four and press ENTER, or just press the four button. When there are five players, there are 31 coalitions (there are too many to list, so take my word for it). Find the Banzhaf power distribution of the weighted voting system [27: 16, 12, 11, 3], Find the Banzhaf power distribution of the weighted voting system [33: 18, 16, 15, 2]. An election resulted in Candidate A winning, with Candidate B coming in a close second, and candidate C being a distant third. When this happens, we say that player 1 is a dictator. << /pgfprgb [/Pattern /DeviceRGB] >> \hline P_{3} \text { (Conservative Party) } & 5 & 5 / 27=18.5 \% \\ Previously, the coalition \(\left\{P_{1}, P_{2}\right\}\) and \(\left\{P_{2}, P_{1}\right\}\) would be considered equivalent, since they contain the same players. \(\begin{array}{l} xWM0+|Lf3*ZD{@{Y@V1NX` -m$clbX$d39$B1n8 CNG[_R$[-0.;h:Y & `kOT_Vj157G#yFmD1PWjFP[O)$=T,)Ll-.G8]GQ>]w{;/4:xtXw5%9V'%RQE,t2gDA _M+F)u&rSru*h&E+}x!(H!N8o [M`6A2.

If P1 were to leave, the remaining players could not reach quota, so P1 is critical. \(\begin{array}{|l|l|l|} xYMo8W(oRY, In a small company, there are 4 shareholders.

In the election shown below under the Plurality method, explain why voters in the third column might be inclined to vote insincerely. The total weight is .

A player will be a dictator if their weight is equal to or greater than the quota. /Parent 25 0 R Which apportionment paradox does this illustrate? >> endobj You will see the following: Now press the right arrow key to move over to the abbreviation PRB, which stands for probability. How many coalitions are there? The Ultimatum Game is a famous asymmetric, sequential two-player game intensely studied in Game Theory. In the winning two-player coalitions, both players are critical since no player can meet quota alone. The sequential coalition shows the order in which players joined the coalition. In fact, seven is one less than , 15 is one less than , and 31 is one less than . Set up a weighted voting system for this scenario, calculate the Banzhaf power index for each state, then calculate the winner if each state awards all their electoral votes to the winner of the election in their state. In the voting system [8: 6, 3, 2], no player is a dictator. Combining these possibilities, the total number of coalitions would be:\[N(N-1)(N-2)(3-N) \ldots(3)(2)(1)\nonumber \]This calculation is called a factorial, and is notated \(N !\) The number of sequential coalitions with \(N\) players is \(N !\). make a list of sequential . If in a head-to-head comparison a majority of people prefer B to A or C, which is the primary fairness criterion violated in this election? There is a motion to decide where best to invest their savings. stream Every sequential coalition has one and only one pivotal player. \hline \text { North Hempstead } & 21 \\ For a resolution to pass, 9 members must support it, which must include all 5 of the permanent members. When player one joins the coalition, the coalition is a losing coalition with only 12 votes. Notice that player 5 has a power index of 0, indicating that there is no coalition in which they would be critical power and could influence the outcome. First, we need to change our approach to coalitions. No player is a dictator, so we'll only consider two and three player coalitions. In the coalition {P1, P2, P4}, every player is critical. In a committee there are four representatives from the management and three representatives from the workers union. In situations like political alliances, the order in which players join an alliance could be considered the most important consideration. >> For the first player in the sequential coalition, there are 3 players to choose from. So player two is the pivotal player for this coalition as well. Legal. /D [24 0 R /XYZ 334.488 0 null] | For comparison, the Banzhaf power index for the same weighted voting system would be \(\mathrm{P}_{1}: 60 \%, \mathrm{P}_{2}: 20 \%, \mathrm{P}_{3}: 20 \%\). >> endobj Then press the MATH button. \hline P_{2} & 1 & 1 / 6=16.7 \% \\ Not all of these coalitions are winning coalitions.

The Banzhaf power index was originally created in 1946 by Lionel Penrose, but was reintroduced by John Banzhaf in 1965. In a primary system, a first vote is held with multiple candidates.
