"Approval Voting and Scoring Rules with Common Values. / Ahn, David; Oliveros, Santiago.


Research output: Working paper



Consider the problem of deciding a winner among three alternatives when voters have common values, but private information regarding the values of the alternatives. We compare approval voting with other scoring rules. For any nite electorate, the best equilibrium under approval voting is more ecient than either plurality rule or negative voting. If any scoring rule yields a sequence of equilibria that aggregates information in large elections, then approval voting must do so as well.
