Threshold voting leads to Type-Revelation

Author

Listed:
  • Núñez, Matías

Abstract

Under Threshold voting, voters casts ballots which include a vector of cardinal utilities (a type) and a real number (a threshold). We prove that a voter has an incentive to reveal his type: for each insincere ballot, there is a sincere ballot that the voter prefers.
