Traditionally, mechanism design focuses on simultaneous-move games (e. g. , Myerson (1981) ). In this paper, we study mechanism design with sequential-move games, and provide two results on revelation principles for general solution concepts (e. g. , perfect Bayesian equilibrium, obvious dominance, strong-obvious dominance). First, if a solution concept is additive, implementation in sequential-move games is equivalent to implementation in simultaneous-move games. Second, for any solution concept ho and any social choice function f, we identify a canonical operator ^ (ho, f), which is defined on primitives. We prove that, if ho is monotonic, f can be implemented by a sequential-move game if and only if ^ (ho, f) is achievable, which translates a complicated mechanism design problem into checking some conditions defined on primitives. Most of the existing solution concepts are either additive or monotonic.
