Time consistency is an important property of any solution to a cooperative dynamic game. If the solution satisfies this property, players do not need to revise it and break a cooperative agreement. Strong time consistency is a stricter property which is applicable to cooperative set solutions. In this paper, the authors examine a class of linear-state games which come into use in many applications of dynamic games. Considering the core as the solution of the game, the authors provide sufficient conditions for its strong time consistency. In case of its inconsistency, the authors show how core elements can be realized using a strong time-consistent imputation distribution procedure.
