论文摘要
我们考虑发件人接收器游戏，其中发件人和接收器是通信网络中的两个不同节点。因此，发件人和接收器之间的通信是间接的。我们询问何时有可能将直接通信游戏的均衡成果稳健地作为网络上间接通信游戏的均衡结果。强大的实施要求：（i）实施独立于中介机构的偏好，（ii）在所有历史上保证实施与中介机构单方面偏差一致。当且仅当发送者和接收器直接连接或在发件人和接收方之间存在两个不相交的路径时，才有可能进行直接通信的强大实现。
We consider sender-receiver games, where the sender and the receiver are two distinct nodes in a communication network. Communication between the sender and the receiver is thus indirect. We ask when it is possible to robustly implement the equilibrium outcomes of the direct communication game as equilibrium outcomes of indirect communication games on the network. Robust implementation requires that: (i) the implementation is independent of the preferences of the intermediaries and (ii) the implementation is guaranteed at all histories consistent with unilateral deviations by the intermediaries. Robust implementation of direct communication is possible if and only if either the sender and receiver are directly connected or there exist two disjoint paths between the sender and the receiver.
