Abstract

It is suggested that the most natural mathematical model for a market with “perfect competition” is one in which there is a continuum of traders (like the continuum of points on a line). It is shown that the core of such a market coincides with the set of its “equilibrium allocations,” i.e., allocations which constitute a competitive equilibrium when combined with an appropriate price structure.
