Se propone un concepto de solución para los juegos cooperativos que consiste en una estructura de coaliciones estable con su correspondiente vector de pagos a los jugadores basado en el valor de Shapley. La definición de estabilidad está ligada a la idea del equilibrio (fuerte) de Nash para los juegos no cooperativos.

El valor de Shapley asigna un pago a cada jugador de un juego cooperativo suponiendo que todos los jugadores forman, finalmente, la coalición global y tienen que repartirse la utilidad que esta coalición puede conseguir. Sin embargo, en algunos juegos cooperativos, los jugadores prefieren otras maneras de organizarse (formando una estructura de coaliciones que no necesariamente contempla la unión global de todos ellos) que permite a algunos de ellos mejorar el pago que les otorgaba el valor de Shapley inicialmente.

Nos preguntamos también cómo son los juegos en los cuales la gran coalición es la mejor opción para los jugadores.

Keywords: juego cooperativo, valor de Shapley, estructura de coaliciones, equilibirio de Nash, estabilidad.
