摘要：
Four axioms are placed oil a correspondence from smooth, non-atomic economies to their allocations. We show than thr axioms categorically determine, the (coincident) competitive-core-value correspondence. Thus any solution is equivalent to the above three if, and only if, it satisfies the axioms. In this sense our result is tantamount to an ''equivalence principle.'' At the same time, our result implies that the three solutions themselves are determined by the axions and so serves as an axiomatic characterizational of the well-known competitive (or core, or value) correspondence.
