　　讲座摘要：In this paper, we propose an instrument for stabilizing the grand coalitions in unbalanced cooperative games via cost vector adjustment (CVA). To study the CVA instrument, we define its associating problem as a constrained inverse optimization problem (CIOP), and then formulate the optimization problem as a linear programming. We investigate the sufficient, the necessary and the sufficient and necessary conditions under which the CIOP is feasible: in the infeasible case, suggest to unify the CVA instrument with some existing instruments for stabilizing the grand coalitions; while in the feasible case, we study the computational complexity of the CIOP and propose two types of solution methods, namely, the cutting plane and the cone optimization methods, to solve it. In the end, we demonstrate the applicability of the CVA instrument to the weighted matching and uncapacitated facility location games.
