Abstract We develop a unified derivation of asymmetric pure strategy equilibria and their optimality in the canonical common interest voting model Austen-Smith Banks (Am Polit Sci Rev 90(1):34–45, 1996). also study relationship between most efficient equilibria, which have remarkably simple intuitive structure, symmetric mixed equilibrium that has been commonly studied literature. In particular, while efficiency under unanimity rule is known to be decreasing number voters, does not depend on voters above threshold equilibria.
