The paper deals with a measure theoretic model of a pure exchange economy. There are two kinds of traders: "big" traders, represented by atoms of the measure space, and "small" traders, represented by the atomless part of the measure space. The restriction of an allocation to the atomless sector is called competitive if there exists a price vector such that the consumption of every "small" trader is a maximal element (in terms of his preference) in the budget set defined by that price vector and by his initial endowment. We consider the set of allocations that are not blocked by any atomless coalition, or by the complement of any atomless coalition, and call it the $\scr{I}^{2}\text{-core}$. The main results of the paper consist in defining sufficient conditions under which allocations in the $\scr{I}^{2}\text{-core}$ have a competitive restriction to the atomless sector, and vice versa. The economic implications and significance of the results are briefly discussed.
