Strategic Voting with Almost Perfect Signals

Author

Listed:
  • Venturini, Andrea

Abstract

A standard assumption in the literature of strategic voting is the independence of signals. Each juror observes a signal at the interim stage of the game. Then she votes according to her private information in order to maximize her expected utility. This work introduces a dependency between signals, reflecting a more realistic situation, in which evidences can be incontrovertible. We give a full characterization of the symmetric equilibria in non-weakly dominated strategies and we provide a benchmark between the classical approach and this new one.
