Resumen de Marginality and the position value

C. Manuel, Eduardo Ortega Castelló, Miguel Angel Pozo Montaño

• We present a new characterization of the position value, one of the most prominent allocation rules for communication situations (graph-games or games with restricted communication). This characterization includes the PL-marginality property, an extension for communications situations of the classic marginality for TU-games, as well as component efficiency and balanced link contributions for necessary players.
