Question

Use the Banzhaf power index to determine the power index for each player. Consider the voting system {18: 9, 6, 3, 3, 2}. Use the winning coalitions below to find each player’s power index.

  • {P1, P2, P3}
  • {P1, P2, P4}
  • {P1, P2, P3, P4}
  • {P1, P2, P3, P5}
  • {P1, P2, P4, P5}
  • {P1, P2, P3, P4, P5}
 a
P1 = 33.3%, P2 = 33.3%, P3 = 11.1%, P4 = 11.1%, P5=0%
 b
P1 = 37.5%, P2 = 31.5%, P3 = 11.1%, P4 = 11.1%, P5 = 8.8%
 c
P1 = 33.3%, P2 = 33.3%, P3 = 11.1%, P4 = 11.1%, P5 = 3%
 d
P1 = 33.5%, P2 = 37.5%, P3 = 11.1%, P4 = 11.1%, P5 = 6.8%
