Abstract

This paper defines the extensive form correlated equilibrium (EFCE) for extensive games with perfect recall. The EFCE concept extends Aumann’s strategic-form correlated equilibrium (CE). Before the game starts, a correlation device generates a move for each information set. This move is recommended to the player only when the player reaches the information set. In two-player perfect-recall extensive games without chance moves, the set of EFCE can be described by polynomial number of consistency and incentive constraints. Assuming P 6= NP, this is not possible for the set of CE, or if the game has chance moves.
