Abstract

En esta nota se generalizan los conceptos clásicos de núcleo y Equilibrio de Edgeworth de una economía de intercambio. Para ello, se introducen las nociones de S-Núcleo y S-Equilibrio de Edgeworth, donde S es un conjunto de coaliciones permitidas, y se estudian algunas propiedades. Se aporta una caracterización del concepto S-Equilibrio de Edgeworth, mediante la definición de los conceptos equivalentes de S-Nucleo fuzzy y S-Nucleo fuzzy en con coeficientes racionales. Se prueba que, bajo determinadas hipótesis, para conseguir asignaciones del nucleo, de equilibrio walrasiano, equilibrios de Edgeworth 0 asignaciones del nucleo fuzzy de una economía, no es necesario considerar la formación de todas las coaliciones, sino que es suficiente permitir el veto de un subconjunto de coaliciones S, distinto del total. Estos resultados se obtienen tanto para economías definidas sobre un espacio de mercancias de dimensión finita, como para el caso infinito-dimensional.
