A natural mechanism to choose the deserving winner when the jury is made up of all contestants


  • Pablo Amorós

    () (Department of Economic Theory, Universidad de Málaga)


We analyze the problem of a jury choosing the winner from a set of agents when the identity of the deserving winner is common knowledge amongst the jurors but each juror is biased in favor of one di¤erent agent. We propose a simple and natural mechanism that implements the socially optimal rule (the winner is the deserving winner) in subgame perfect equilibria.
