[1] The core is a game theory solution concept that identifies a stable allocation of payoffs among players. In simple terms is a set of outcomes such that no group (coalition) of players can deviate and achieve a better payoff for all its members and, hence, where no coalition has an incentive to break away from the grand coalition. The idea is seminally attributed to the Anglo-Irish economist Francis Y. Edgeworth (1845-1926) when illustrating feasible allocations not improvable by individuals or groups of traders (1921). Later on, such a concept was generalized as “core of a cooperative game” (1959) by the Canadian computer scientist and mathematician Donald B. Gillies (1928-1975).
[2] Since the core is a solution concept that identifies stable payoff allocations among players, namely set of outcomes that no group of players can deviate from achieving a better payoff for all its members, in this situation no player can reasonably complain.
[3] Robert J. Aumann's (1964) core equivalence theorem states that the set of core allocations in an atomless economy (e.g. an economy with a continuum of players) coincides with the set of Walrasian equilibrium allocations, characterized by a general equilibrium price vector.
