[On egalitarian values for cooperative games with a priori unions. TOP. 2020;28:672–688]. In this study, we provide new axiomatic characterizations of these values. Furthermore, using the equal surplus division value in two steps, we propose a new coalitional value. The balanced contributions and quotient game properties generate a different modification of the equal surplus division value.engAtribución-NoComercial 4.0 Internacionalhttp://creativecommons.org/licenses/by-nc/3.0/es/Cooperative gamesCoalitional valuesEqual division valueEqual surplus division valuejournal articleopen access10.1080/02331934.2021.1995731
