The Proportional Lottery Protocol is Strongly Participatory and VNM-Strategy-Proof


  • Stefano Vannucci



A voting protocol is said to be strongly participatory if for any player i and any strategy profile either the outcome is i‘s preferred one or has a strategy which would ensure her a better outcome, and VNMstrategy proof if at any preference profile the set of sincere strategies of each player is a VNM-stable set. It is shown that the proportional lottery (PL) modular voting protocol is both strongly participatory and VNMstrategy proof.
