This paper studies the duality between the blocking power and producing ability of all sub-coalitions in coalitional TU and NTU games, and it establishes three main results: 1) the usual TU (NTU) core is empty if and only if (if) sub-coalitions can produce a higher payoff than the grand coalition’s payoff; 2) the new core is always non-empty; and 3) optimal (efficient) coalitions will form in coalitional TU (NTU) games in a manner determined by their shadow values.
