Abstract (distribution restricted)
In an exchange economy with a continuum of traders, we establish the equivalence theorem on the core and the set of competitive allocations without assuming monotonicity of traders' preferences. Under weak assumptions we provide two alternative core equivalence theorems. The first one is for irreducible economies under Debreu's assumption on quasi-equilibria. The second one is an extension of Aumann's theorem under weaker assumptions than monotonicity.
