core coincides with the set of cost-minimized Walras allocations. Because of the indivisibility, the preference …

. We prove that the strong core coincides with the set of cost-minimized Walras allocations which satisfy both the …

We show that this equivalence holds only in an atomless … economy by giving two examples of the sequence of replica economies such that in any replica economy, there exists a core …
