Abstract

En este artículo se obtienen dos caracterizaciones de las asignaciones de equilibrio walrasiano en economías de intercambio con un número finito de consumidores. Ambas caracterizaciones se establecen en términos del poder de veto de la "gran coalición", formada por todos los agentes de la economía. En un primer resultado probamos que una asignación es de equilibrio si y sólo si no está dominada por la "gran coalición" en cualquiera de las economías que resultan de alterar las dotaciones iniciales, tan poco como se quiera, en una dirección precisa. Nuestro segundo resultado de equivalencia establece que cualquier asignación no walrasiana está vetada por la "gran coalición" en la que todos los individuos participan con recursos arbitrariamente próximos a sus dotaciones iniciales.
