摘要：
We establish the existence of a competitive equilibrium in a two -period stochastic economy with incomplete financial markets by using Sperner's lemma. Our existence result covers (but is not limited to) several results in the literature, including the cases of nominal and num & eacute;raire assets. Moreover, there may exist a continuum of equilibrium prices.
