Existence of pseudo-equilibria in a financial economy
Résumé
We prove the existence of a pseudo-equilibrium in a financial economy with incomplete markets in which the agents may have nonordered preferences. We use a fixed-point-like theorem of [5] that generalizes the results by Hirsch, Magill and Mas-Colell [18] and Husseini, Lasry and Magill [19] to encompass the framework considered by Gale and Mas-Colell ([14], [15]).
