摘要
We consider the implementation problem under incomplete information and interdependent values. This paper provides a necessary and sufficient condition for a social choice function to be ex post self-implementable in general environments. A social choice function is ex post self-implementable if it is fully ex post implemented by the associated direct revelation mechanism. We introduce a new monotonicity condition called restricted monotonicity and show that this and ex post incentive compatibility are necessary and sufficient for ex post self-implementation.
