三、主要内容：This paper demonstrates the possibility of a symmetric “binary-action mixed-strategy equilibrium” in the nested Tullock contest model (Clark and Riis, 1996, 1998b) with multiple nonmonotone prizes. In this symmetric equi- librium, every player adopts the same mixed strategy: Each exerts zero effort with some probability and a constant positive effort otherwise. This new type of equilibrium can coexist with the pure-strategy equilibria established in the literature; it may exist even when those pure-strategy equilibria do not. The coexisting (mixed and pure-strategy) equilibria may induce different levels of effort supply.
